Conveyor equipment selection factors Dust

Principles and characteristics of dust removal equipment due to a variety of different types of choice, but its collection efficiency, investment and maintenance costs, running

costs, system layout, structure, materials and space requirements are all different. For no experience in the use of special dust problem, and Metal detector for food equipment manufacturing

Manufacturers of filter selection process.
Factors affecting removal equipment selection
(1) dust concentration and particle size
Dust concentration in the air and the dust particle size range is large, can be 0.22 ~ 45g/ms dust concentration or higher, the average particle size difference (big or less

than the average) also varies with the material.
(2) the degree of removal required
Requirements dust depends on the study of specific issues, clean air after the dust is recycled or discharged directly into the atmosphere. Equipment to be considered in the

evaluation of the need for high efficiency, high cost of equipment such as electrostatic precipitators; efficient, medium-cost equipment such as dust bag

Or wet scrubbers and low-cost primary dedusting devices such as cyclones and so on. If at the outset that the first two precipitators consider any one, you may want to consider

associated with the main primary dust removal equipment.
Discharged outside through the dust after cleaning air, dust depends on device location, to compare the way different types of dust into the atmosphere and its amount of dust;

nature of the pollutant and the relevant laws and regulations requirements.
The number of fugitive dust affect device choice for a certain concentration of the gas, the greater the volume of emissions, requires greater the better dust removal equipment.

General equipment selection, require fugitive dust allowed to limit the amount of pollutants in the atmosphere to a minimum, reasonable construction investment and

Maintenance costs and the need to conform to the total air pollution provisions.
(3) the characteristics of flow
Airflow characteristics have a greater impact on equipment selection, weaving baghouse filter bag can only be used for a lower temperature of the air, over 80 degree heat flow

can not be used through the condensation of water vapor can cause dry dust dusty air produce agglomeration and clogging. Corrosive chemicals containing gas

Stream of dry dust bag and also cause corrosion of metal; the wet dust collector, when mixed with water will cause great damage.
(4) dust characteristic
Dust with the kind of features will also affect the choice of equipment, such as: dust particle size, shape and density will exclude certain types of dust; such as metal

polishing dust adhesion material bonded to the filter element may be blocked on Channel; chemical substances and dust components may be

With wet scrubbers or cause corrosion; abrasive materials at moderate or high concentrations will quickly wear metal surfaces; combustible powder materials required to select

safe precipitator.
(5) energy requirements
Performance can be achieved for all types of dust, they need to get to the total energy consumption of the possibility of an electrostatic precipitator for example, you can

choose low pressure drop, low power consumption to compensate for the high investment.
(6) Method of ash
Precipitator ash discharge method with materials, process equipment, and the amount of dust precipitator design changes. Dry dust ash can be continuously or intermittently

through the flap valve, rotating or flashing unloader valve discharge to a Airport conveyor or containers. Dry material may be generated when the precipitator ash soil secondary play

Flying problem.
Wet scrubber ash can be intermittent or continuous extrusion dewatering conveyor wing material or slurry. Although the discharged slurry is also processed, but the second dust

problems can be eliminated.
