Because the filter material is folded into a cylinder, the filter material layout density is large, so the dust removal mechanism is compact and the volume is small. The height of the filter cartridge is small, the installation is convenient, and the maintenance workload is small; The filter area of the same volume dust collector is relatively large, the filter wind speed is small, and the sniper is not big; Filter material folding requires strict sealing at both ends and no air leakage, otherwise it will affect the dust removal effect. The filter drum type dust collector is composed of air inlet pipe, air exhaust pipe, box, ash hopper, ash cleaning device, filter barrel and electric control device. The filter cylinder in the dust collector arrangement is very important, the filter cylinder can be vertically arranged in the dust collector box flower plate, can also be inclined arranged on the flower plate, fixed with bolts, and with rubber pads, the lower part of the flower plate is divided into filter chamber, the upper part is divided into clean gas chamber, the filter cylinder treatment is fixed with bolts, the convenient method is automatic locking device and rubber compression device, these two methods, It is convenient for installation and maintenance. The tilt Angle of the dust hopper should be fixed according to the rest Angle of the dust, and generally should not be less than 60 degrees.
Analysis of the relationship between filter material and dust quality of pulse bag dust collector:
First, when the water content is large and the dust concentration is large, it is appropriate to choose not afraid of water, filter material (or anti-condensation filter material) or coated filter material (the base cloth should be needled felt that is not afraid of water treatment).
When the dust-containing gas contains acid and alkaline and the gas temperature is less than 190°C, Ryton (polyphenylene sulfide) needle felt is often used. When the gas temperature is less than 240°C and the sex requirement is not too high, P84 (polyimide) needle felt is selected.
Third, when the dust-containing gas is flammable and explosive gas, choose to prevent electrostatic tapefibre needle felt, when the dust-containing gas has the corresponding water and flammable and explosive gas, choose not afraid of water to prevent electrostatic (three prevention) tapefibre needle felt.
The filtration speed is the key factor in the selection of dust collector, which should be determined according to the properties of dust or dust, application occasions, dust particle size, viscosity, gas temperature, water content, dust concentration and different filter materials.
Fifth, when the dust particle size is fine, the temperature and humidity are good, the concentration is large, and the viscosity should be low. Such as ≤1m/min; On the contrary, the optional high value is generally not more than 1.5m/min. For dust particle size is very large.
6, normal temperature, dry, non-viscous, and low concentration, 1.5~2m/min can be selected. When the filtration speed is selected, it should be calculated that the net filtration wind speed should not exceed the above value when reducing the filtration area of one room (when cleaning).
7. The filter material should be considered according to the temperature of the dust-containing gas, the amount of water, the properties of acid and alkali, the viscosity, concentration and grinding of the dust.
8, generally in the small water content, no acid according to the dust gas temperature to choose, normal temperature or ≤130°C, commonly used 500~550g/m2 polyester needle felt. <250°C, use aramong Nomex needle felt or 800g/m2 glass fiber needle felt or 800g/m2 double glass fiber fabric or Flumas [FMS] high temperature filter material (fluorine gas can not use glass fiber material).
grinding dust collector exporter Dust properties include specific resistance, particle size, true density, bailing property, hydrophobicity and hydrohardness, flammability, explosion, etc. The specific resistance is too large or too small dust should not be used electric dust collector, bag dust collector is not affected by the specific resistance of dust; The influence of dust concentration and particle size on the rate of electrostatic precipitator is obvious, but the influence on the bag dust collector is not obvious. When the dust concentration of the gas is good, the pre-dust removal device should be set up before the electric dust collector; The type of bag dust collector, cleaning method and filtering wind speed depend on the nature of dust (particle size, scoop property); Wet dust collector is not suitable for purifying hydrophobic and hydraulic dust: the true density of dust has obvious influence on gravity dust collector, inertia dust collector and cyclone dust collector; For the dust with large new adhesion, it is easy to cause the working face of the dust collector to tie or clog, so it is not suitable to use dry dust removal; When dust purification meets water and can produce combustible or explosive dangerous mixture, wet dust collector can not be used.
