Screw in the NID dry desulfurization system application

Dust on the distribution NID desulfurization system , usually electrostatic precipitator hopper bottom ash hopper designed to be boat , bottom ash hopper will connect 550-800mm

wide fluidized chute . The role of the fluidizing chute is in the flow of air under the action of the chute to the desulfurization transport fluidization bottom ash

Position , which is usually less than 10 degrees inclination . However, in the last ESP field , if the chute or the use of fluidized , then it is inevitable there will be a

small amount of fine dust raised by the wind streaming from the electrostatic precipitator outlet horn escape and, thus resulting in dust emissions exceeded.

So, finally a farm hopper ash gravity skatewheel conveyor design is mostly used .
Because circulating ash agglomeration and caking easily hardness after bigger, so will the spiral blade is designed for intermittent blade . Such rotation of the spiral blade is

not just a transport function , as well as for cutting the material caking crushing functions. If it is a material accumulation occurs elbow , can also be employed

Cleaning artificial way , used to extend the operating life of the spiral . NID reactor bottom roller conveyor , which is usually designed transport capacity of 10m3 / h,

diameter 400mm, spindle speed 30rpm.
NID dry desulfurization sorbent system is quicklime , which requires particle size ≤ 3mm. In fact, generally made ​​of limestone blocks burned lime , it was time to go through

two grinding process , it will become a particle size of several tens or even hundreds of microns, quicklime powder , and more

Plus the convenience of transportation and storage. Quicklime quicklime position is temporary storage device , the volume of the system generally designed to accommodate the

amount of lime used 3-10 days , but also the body close to the device as possible , thus reducing transport distances.

Belt conveyor

Continuous conveyor belt is a continuous Turn conveyor is fixed or migration lifting one of the main types of transport in which transport is characterized by the formation of a

mount point to mount a continuous material flow between points , relying on continuous material flow the overall movement to complete the logistics from the loading point to the

unloading

The delivery point . curve conveyor in industry, agriculture , transportation and other enterprises, the production process is continuous conveyor composed of rhythmic flow

transport line indispensable component.
Continuous conveyors can be divided into :
( A ) a flexible conveyor traction objects , such as belt conveyors, slat conveyors , scraper conveyors , bucket conveyors, escalators and ropeway , etc. ;
( 2 ) does not have a flexible traction conveyor objects such as screw conveyor , vibrating conveyors ;
( 3 ) Pipe conveyor ( fluid ) , such as air- conveying means and the hydraulic pipes.
Which is a continuous conveyor belt conveyor is the most widely used , reliable belt , transmission capacity , transmission distance is long , easy to maintain , to adapt to the

metallurgical coal , machinery and electric power, light industry, building materials, food and other departments .

Classification and characteristics of belt conveyor

< 1> There are several ways belt classification , according to material transport conveyor structure can be divided into two categories, one is the common type of conveyor, belt

conveyor belt transport of such materials in the process, the band was trough , the next band was flat shaped Belt conveyor rollers hold , conveyor belt

Exterior geometry are flat ; another one is special structure conveyor, each have their own transport features.
<2 > Various characteristics of belt conveyors
(1) QD80 light fixed belt conveyors QD80 light fixed belt conveyors with TD Ⅱ type compared with thinner , and lighter loads , transport distance is generally not more than

100m, the motor capacity not exceeding 22kw.
(2) DX -type steel cord conveyor belt which is a high strength , the conveyor belt core in parallel thin rope , a Mine conveyors transport distance of up to a few kilometers to tens

of kilometers.
(3) U -shaped trough conveyor belt it is called , which was characterized by the trough-shaped belt conveyor idler common angle are from 30 ° to 45 ° up to 90 ° to the

conveyor U-shape. Thus have squeezed between the conveyor belt and the material , causing the friction material on the tape

Increases, so that the transport of the conveyor inclination up to 25 °.
( 4 ) U-shaped tubular belt conveyor belt conveyor belt further into the groove , and finally form a circular tube , tubular belt conveyor is because the belt is rolled into a

tube , it can achieve close close transportation of materials, powdered materials can significantly reduce environmental pollution , and can be

In order to achieve the bending operation.
( 5) The air-cushion belt conveyor is not running on the conveyor roller on , but in the air film ( air ) on the run , eliminating the roller , with no moving a gas chamber with

a hole disk -shaped groove kindly room replaced the running rollers, moving parts reduces the total equivalent mass decreases resistance

Force decreases , efficiency and smooth running belt speed can be increased . But generally its fragmentation transportation of materials does not exceed 300mm. The method of

increasing the logistics section of the conveyor idlers except Forced into a trough , you can also change the belt itself , the conveyor belt carrying surface made of vertical

Edge , and with a transverse bulkhead. Generally the vertical side wall made ​​of wavy , so called wavy belt , this model applies to a large inclination angle of 30 ° or more ,

up to 90 °.
( 6 ) Pressure belt belt conveyor belt which is an auxiliary pressure on the material . This conveyor main advantages are: transport of materials up to a maximum angle of 90 °,

running speeds of up to 6m / s, transmission capacity does not change with the inclination can achieve loose materials and toxic

Material custody transfer . The main disadvantage is the complex structure , belt wear and energy consumption increase bigger.
( 7 ) It is boundless rope tow rope conveyor belt transport transport and a combination product , with both high strength rope , traction and flexible features, but also has a

continuous belt transportation , flexible benefits.

Pneumatic conveying and material properties of dust Profile

First, dust
Solid material called elementary solid particles, dispersed in the air for a certain time called solid particles of dust. International Organization for Standardization,

particle size less than 75 microns is defined as powered roller conveyor dust suspended solids.
1 generates
The production process of the solid material for mechanical crushing, grinding dust is generated. Such as: coal crushing.
Metal smelting or heating of the object, the physical and chemical processes of sublimation or vapor in the air condenses to form tiny particles or oxidation. Such as: coal or

coke oven coke pushing process.
Or incomplete combustion of organic matter combustion, emissions species contains a lot of tiny dust particles and smoke. Such as: coal spontaneous combustion or inadequate

supply of oxygen and other reasons can not fully burn, smoke exhaust material contains various forms of dust.
In the powder material mixing, transfer, screening, packaging and discharging the production process, a large number of dust particles escape from the device and so the gap.
(2) the nature of
(1) invasive
Dust invasive means of solid particles in contact with the cleansing liquid, the liquid surface of the infiltration of dust skate roller conveyor particles. This phenomenon performance liquid on the

surface of dust particles the size of the force. Usually the degree of infiltration of water on the dust particles of dust into the hydrophilic and hydrophobic categories.
(2) explosive
Reaches a certain concentration of industrial dust in the air to meet fire, discharge, temperature and friction effects, explosion may occur, a phenomenon called dust explosion.
(3) Abrasion resistance
Abrasive dust usually refers to the degree of abrasion of the device, wear dust with its own hardness and shape of the hardness, surface roughness of the large abrasive dust.
3 Classification
(A) by nature
Inorganic dust include: mineral dust (such as sand, coal); metal dust (such as iron, tin, lead and their compounds); artificial inorganic dust (such as silicon carbide, cement,

glass fibers).
Organic dust: Includes vegetable dusts (such as wood, tobacco, flour); animal dust (eg skins, skin, hair); artificial organic dusts (such as explosives, organic dyes, plastics,

chemical fiber).
Mixed dust, dust of the various mixtures (such as metal grinding, abrasive dust, metals and mixtures thereof).
(2) according to particle size classification
Dust: particle diameter greater than 10 microns, the electrostatic air to accelerate sedimentation, non-proliferation.
Sand and Fog: Dust particle diameter is between 10-0.1 microns in static air at constant speed landing, not spread.
Dust: particle diameter of 0.1 and 0.001 microns, because of its size is close to the air molecules, by the collision of air molecules showed Brownian motion, almost no

settlement or very slow and tortuous descent. Since dust particles of different sizes, the length of the residence time in the air is different, the processing side

Different method.
Second, the material properties
Pneumatic conveying system design, the material particle characteristics determine whether to adopt the pneumatic conveying and pneumatic conveying in what form. Material

properties including particle size and distribution, shape, density, hardness, brittleness, compressibility, permeability, viscosity, separation, explosive and electrostatic

Effects, etc..
1 particle shape
The shape of the suspended particles have a greater impact speed. The same kind of spherical particles of suspended material in the maximum speed, a variety of other irregularly

shaped particles suspended speed is smaller. Suspension rate is small, in the same transport gas velocity, the material will be deposited on the bottom of the tube, by the

movement of materials between the push

Or stationary. Polygonal particle friction, surface bumps and more particles tend to smoke and melt.
(2) Bulk density
The bulk density of the material the greater the energy consumption for transporting the greater. Such as the use of air power to transport, requires enhanced conveying

velocity. Gas velocity is too low, will inevitably result in the deposition of the bottom of the tube material, the residual amount of increase in transport Hou.
3 moisture
Increase the moisture content of materials, in addition to adhesion and prone to clogging pipes, but also affect the device transport capacity. For example, when the gas

conveying the water content of 0-3% of clay, each increase of 1% moisture, transport capacity is reduced by 15%. Generally use pneumatic conveying of material moisture content

of 6% to

Under high pressure to send a maximum moisture content of the material does not exceed 4%. Typically, the material from the vacuum blower can be compared using a slightly higher

moisture content of pressure-feeding. Water content, the material is difficult to produce static electricity, sticking down.
4 hygroscopicity
It is easy to agglomerate material is hygroscopic, it will affect the amount of transmission capacity and residual materials. Pneumatic conveying the greatest difficulty lies in

ashes, ashes contact with the atmosphere 1-2 hours hygroscopic sticky.
5 of viscous
The viscous material will directly affect the accumulation of material in the pipeline, thus affecting the normal transport. Sometimes sticky particles can cause serious

problems arise pipe blockage.
6 Wear
The physical characteristics of the material wear of the pipeline has a direct relationship between the amount of the wear degree of the material and conveying stone learning

function of speed.
7 compressibility
The compressibility of the material implies a material density of the gas and the material deposit and the relationship between permeability, which directly affects the material

movement in the pipeline, especially at high feed rate and under conditions of low-speed transport.

Spiral pneumatic pump working principle of the definition and

Spiral pneumatic conveying pressure feed pump is a pneumatic heavy duty conveyor equipment for the material can be used to transport cement, raw materials, coal, fly ash and other

powdered materials, transmission distance of 200m, the compressed air pressure of 0.2-0.4MPa. Aspirated pressure pneumatic Power Roller Conveyor equipment belonging to the high-voltage

transmission equipment.
Spiral pneumatic pump with cantilever arm-and-two types, each pair into a single pipe and double pipe screw pump two kinds.
The right part of the screw shaft with spiral, helix mounted in the sleeve, the left portion mounted in the bearing box, the end portion connected to the motor through the

coupling, speed 900-1000r/min. Material from the inlet port to join spiral, pushed to the discharge port, unloading into the mixing chamber. Lower loading of the mixing chamber

There are two rows of nozzles, the compressed air through the nozzle boxes from the spray nozzle into the mixing chamber, mixing with the materials and into the pipeline.
Mixing chamber air pressure is higher, likely to cause material along the helical gas inlet port and the sleeve to the back. To prevent backflow of gas feed, variable pitch

spiral coil manufactured, pitch direction gradually decreases towards the material, the material feed inlet orifice pitch pitch smaller than 30%, so that the material inside the

spiral is gradually

Tight squeeze in the discharge port formed dense material bolt, you can prevent the gas feed back. In order to ensure a certain degree of dense material bolt and prevent

inadequate or interrupted the feed gas feed back, in the discharge port is equipped with valves, valve arm hinged valve, the valve arm is fixed to the shaft, the shaft ends

protruding machine

In addition, and equipped with lever and weight, so that the valve on the discharge port to maintain a certain pressure. When the bolt material pushed to live relatively close

to the top to open the unloading valve in the feed inadequate or interrupted, the valve then promptly closed.
In order to prevent the intrusion of material feed inlet bearing, air sealing tube to pass into the air bearing, the formation of "air sealing."
Arm Spiral pneumatic pump as shown. It cantilevered spiral pneumatic pump is the main difference with a screw shaft supported at both ends, eliminating the spiral at the

discharge end of the swing, tend to reduce the wear sleeve and screw and removed the material outlet valve. In order to prevent the material

Entering the bearing, the bearing with compressed air to form a gas seal.
Spiral pneumatic pump The main advantage is that in the high pressure continuous-feed; throughput is easy to control, simple structure, compact structure, body height is small.

Can be used for continuous transportation of materials, and can be transported in the 0-100% of rated capacity under variable transmission, transportation process without

pulsation, throughput up to several

One hundred tons, transported in the same amount under the premise of its smallest.
Its main drawback is the power consumption, supply and consumption of compressed air power almost equal; screw and bushing wear quickly, maintenance workload, demands for long-

distance transport large amounts of process system should not be used.

Light conveyor technology status quo is what

Belt conveyor belt is the main component of the role of super-bearing materials, the use of belts as a transportation carrier and other modes of transportation, compared with

the safe operation, easy to use, easy maintenance, low cost and freight can achieve continuous and shorten the transport distance, etc. . Light Telescopic belt conveyor belt

Is a conveyor belt of fine products, its allowable working tension is less than 50N/mm, with a thin belt body, good dimensional stability, high tension, bright colors. Safe and

nontoxic characteristics. Widely used in food, medicine, electronics, tobacco, printing, packaging, wood, textiles, building materials, pay

Pass, postal, logistics and other industries. For goods, luggage, bulk material transfer and internal factory production assembly line and sideline products processing, also

known as the process zone. Fifteen period, the domestic production of light-duty conveyor belt a breakthrough, and gradually occupy in the Extendable conveyor belt industry

Important position, type specification has reached hundreds of different kinds, in many fields has been widely used.
A lightweight conveyor belt structure: light conveyor belt consists of cover, skeleton layer, the bottom, the skeleton is there mezzanine floor above the fabric. Cover is a

light conveyor belt conveying surface, according to the nature of the material transport, should have good heat resistance, oil resistance, water resistance

Resistance, aging resistance, corrosion resistance, antistatic, non-toxic, etc., materials are rubber, rubber blends, PVC, TPU, TPE, polyamide and fabrics. The core skeleton

layer fabric is generally one to three, the most commonly used for the floor. Warp the fabric material with a high modulus low stretch polyester filament as

More commonly used 1000D and 1500D two kinds. With polyester filament yarn, polyester monofilament nylon filament several, when the conveying transverse rigidity is required

when the choice yarn is a polyester monofilament as a skeletal layer of polyester fabric. Fabric structure by weaving style is plain, twill and straight through straight weft,

etc.

. To ensure that the cover layer and between the layers with good adhesion. Need to be activated or impregnated fabric processing. Bottom is lightweight belt transmission

surface, either supporting or roller support plate are in contact with the supporting material and transmission, usually skeleton fabric, and some light

Conveyor bottom layer is laminated and the cover layer or coating of the same material. Laminated material can be the same as or different from the coating. The thickness of the

light conveyor belt is generally 0. 5-4mm, between the thickness of not more than 7mm.
Two light conveyor belt production and processing technology either rubber or resin light light conveyor belts, production and processing methods used are produced in rolls

products available to users before the need for post-processing, ie cutting a certain length, width, and feed

OK annular joint processing. According to overlay different materials, ring joint approach beveled grinding pick, tooth welding, clinch lap and so on. Take a good head light

conveyor requires a uniform thickness, surface roughness, in order to ensure the accuracy of the material transported.

Conveyor belt and causes damage in the form of what is

Conveyor belt in our production often appears damaged, it is inevitable. But there is a problem we often do not sum up or improve, so often there will be some damage caused by

production disruptions conveyor reasons. Today we'll talk about the loss of Belt conveyor

Some common forms of injury and causes, in order to better identify problems in production, for these situations do better prevention. Here we are concerned about the situation

of several common Telescoping conveyors belt injury;
A conveyor belt longitudinal tear causes
      1 shock and vibration caused by fasteners loose and fell off, causing the coal chute liners, guide plate, etc. fall.
(2) within the inclusion of foreign material, foreign body rigid, angular, coal chute blockage Jisi.
3 roller defect, roller frame cause scratches.
4 belt running after being caught on the rack.
5 sweeper winding roll (return sweeper), loose bolts, there are a harbinger of spring.
Two reasons conveyor cracking
1 space due to size restrictions, the curved conveyor belt more times.
2 connectors for a variety of reasons when curing more than twice vulcanization.
Three reasons conveyor curing joint tear
1 small diameter bend pulley, conveyor withstand large bending stress.
(2) poor quality belt vulcanized joints, especially more than two vulcanized, decreased joint strength, or in the bonding layer is cut when the canvas, or sanding drain, where

intensity decreases.
3 for Reversible conveyor, lap top and bottom can only in one direction, it is easy on the belt cleaning device, and other equipment angular portion unloading scratches.
4 conveyor duty cycle is short, frequent starting, the instantaneous tension force.
Four belt cover rubber surface Injury
1 tape guide trough the gap between the liner and inappropriate, causing abnormal wear, or the gap at the embedded foreign body, causing abnormal wear or scratches.
2. Guide trough at the material flow and conveyor speed is inconsistent, a large gap, accelerated wear of the plastic surface.
3 roller damaged, causing abnormal wear or scratch tape.

PVC conveyor antistatic agent selected

Because PVC is a good insulator, the surface resistance, poor conductivity, made of PVC material with a Belt conveyor in the course of fire due to friction caused by the belt

body positive and negative charges lose balance and static charge generated in the coal that a place rich gas generated sparks, causing a fire

Or gas explosion. Therefore, we have chosen a suitable conductive material, antistatic agents and flame retardant PVC plastic cover to reduce the surface resistance, to ensure

that the spiral conveyor belt surface resistance of less than 3 × 108Ω. PVC plastic cover for the original formulation of the quaternary ammonium salt cationic antistatic agent CN-3

itself, heat resistance

Poor, vulnerable thermal decomposition, thereby reducing the thermal stability of PVC shortcomings, we used to reduce the dosage, adding special conductive carbon black

conductive material way to make flame-retardant PVC conveyor belt has good antistatic properties. Through the use of a reasonable match between the two, both the use of

antistatic agents CN-3 hydrophilic

PVC conveyor groups to increase the surface moisture, to form a conductive monomolecular film, to improve the surface conductivity PVC conveyor belt; while also taking advantage

of special conductive carbon black particles in the shear force, the particles become bonded covering the gel in contact with each other to form a large number of conductive

network by л electricity

Promoter in mesh chain movement and a conductive electron transition occurs, to reduce the volume resistivity of PVC flame retardant conveyor.

Conveyor belt Troubleshooting

A belt conveyor belt deviation runtime is the most common faults. To address such failures is important to note the dimensional accuracy of installation and daily maintenance.

There are several reasons for deviation, to be based on the difference between handling different reasons.

1 Adjust the Power Roller Conveyor idlers bearing belt in the middle of the entire belt conveyor idlers deviation, adjust the position to adjust the deviation; idlers in the manufacture

of both sides of the mounting holes are worked into holes for be adjusted. The specific method is belt

Bias which side, which side idlers forward direction toward the belt forward, backward, or the other side. Belt upward direction of deviation is lower roller group should be at

the left, the upper roller group moved to the right place.

2 Install aligning roller group aligning roller group has many types such as an intermediate shaft type, four-link, vertical roller type, etc. The principle is the use of block

or roller rotates in the direction in the horizontal plane lateral thrust block or generate the Automatic belt adjustment belt deviation reaches to the heart of the purpose.

Generally lose the belt

Sending machine or when the total length of the shorter run-time two-way conveyor belt using this method is more reasonable, because the shorter belt conveyors easier deviation

and not easy to adjust. And long belt conveyor is best not to use this method, because self-aligning roller group life belt use would yield

Students have been affected.

3 Adjust the drive pulley and the driven pulley and bend pulley position adjustment bend pulley belt deviation adjustment is an important part. Because a belt conveyor with at

least two to five rollers, all the rollers must be perpendicular to the installation location of the longitudinal direction of the Belt conveyor centerline, if the deflection

Too large deviation bound to happen. Adjustment Method and its group of similar idlers. For the head drum as the drum belt deviation to the right, the right of the bearing

should be moved forward, the belt deviation to the left of the drum, the left bearing housing should be moved forward, also the corresponding the left

Side or right side of the bearing housings after the shift after shift. Rear roller adjustment method and the head drum opposite. After repeated adjustments until the belt

transferred to an ideal location. Adjust the drive or bend pulley in the best pre-install its exact location.

4 tension belt tension adjustment at the adjustment at the conveyor belt deviation adjustment a very important part. Hammer at the upper two tensioning idler pulley in addition

to other than perpendicular to the longitudinal direction of the belt should be perpendicular to the vertical line of gravity, which is to ensure its axis horizontal centerline.

The use of spiral

Tensioned tensioning or hydraulic cylinders, two tensioning roller bearing shall simultaneously pan, to ensure the longitudinal axis of the drum and the belt perpendicular to

the direction. Specific method of adjusting the belt deviation adjustment of the drum at similar.

5 reprinted point blanking position on the belt deviation of reproduced material blanking at the point position on the belt deviation has a very big impact, especially in the

two belt conveyor in the horizontal plane perpendicular to the projection of a greater impact. Usually reproduced points should be considered down two belt conveyor relative

height

. The relative height of the lower horizontal velocity component of the material the greater the impact on the lower side of the belt is greater, while the material is difficult

to center. The cross section of the material on the belt deflection, resulting belt deviation. If the material is biased to the right, then the belt deviation to the left, and

vice versa

Contingent.
In the design process should be possible to increase the relative height of two belt conveyor. In space-constrained mobile bulk material handling machinery down funnel, guide

trough and other pieces of form and size should be seriously considered. General guidance for the width of the trough belt width should be about two-thirds compared together

Appropriate. In order to reduce or avoid the belt deviation increase blocking plate blocking materials, changing direction and position of the whereabouts of the material.

6-way running conveyor belt deviation adjustment bidirectional running belt conveyor belt deviation adjustment than the one-way conveyor belt deviation relative to the

adjustment much more difficult, specific adjustments should be adjusted in a certain direction, and then adjust another direction. Adjustment should be carefully observed

The belt movement direction and the relationship between the deviation tendency, one by one to adjust. Emphasis should be placed on the drive pulley and bend pulley adjustments,

followed by the adjustment of the roller and the material blanking point adjustment. Also note that the belt in the belt section vulcanized joints should be the length direction

of the force are

Uniform, the use of both sides of the chain traction force equal as possible.

Inclined belt conveyor belt repair and maintenance method resolution

  Inclined belt conveyor with a large open-pit resulting from the application, power plants, cement factories and ports, etc., but also has a large transmission capacity, low

energy consumption, easy maintenance, etc., will become dominant in the conveyor. However, at work due to improper use or belt unexpected, will lead skirt

Plastic bucket edges and tear or fall off, replace the belt will increase production costs. To reduce production costs, research and explore large angle belt conveyor belt

repair process points necessary.
  Inclined Turn conveyor belt repair and maintenance method resolution
  Inclined belt conveyor installed idling two hours after the first check the belt for cracks or fall off, if it should be timely treatment; early feeding of design capacity

load of about 50%, after a period of time to determine the correct operation of the normal load and then feeding operation; the course of the

Found that large angle belt conveyor and out side there aggregates, should be promptly stop treatment, to prevent skirts or plastic bucket off.
Inclined 90 degree turn conveyor belt cracking or peeling, repair should note the following:
    1, clean up the site sanitation, and to be bonded skirts, plastic bucket bonding surface and the belt surface clean.
    2, with a polishing machine will be uniform and thin belts, skirts and other bond hair and clean place to play, but the belt canvas layer or can not appear at the uneven

fight hair.
    3, gluing before the first binder with a hardening agent uniformly mixed by a certain percentage, so that the adhesive has cured with a quick, strong bond, heat resistance,

heat aging and bonding does not require a fixed pressure and so on.
    4, gluing coating is to be strong, thin and uniform coating, if the belt canvas fabric layer or other layers or particles to fight hair loss at the obvious, to brush more

than three.
    5, to be dried to a non-stick coating back when skirts or plastic bucket gradually pressed home with the coating, but with a hammer beating from the middle to the edge

ordered to rule out internal air.
