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.

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.

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.
