Dust treatment equipment for building materials processing bag dust collector pulse bag dust collect

The dusty air flow enters the cylindrical dust removal cloth bag from the lower part
When passing through the hole of the filter material, the dust is blocked by the filter material, and the clean air flow passing through the filter material is discharged from the outlet
The dust layer deposited on the material falls off from the material surface under the action of mechanical vibration and falls into the ash hopper

The dust mechanism of bag filter includes separation, inertial collision, interception, diffusion, electrostatic and force action
Screening is one of the main dust mechanisms of bag filter
When the particle size of dust is larger than the pores between fibers in the filter material or the pores between dust deposited on the filter material, the dust is screened and filtered
Because the pores between fibers are much larger than the particle size of dust, the screening effect of common fabric filter cloth is very small at the beginning of filtration, mainly due to the fiber dust filtering mechanism & mdash& mdash; Inertia, interception, diffusion and electric action
However, when a dust adhesion layer is gradually formed on the filter cloth, the effects of collision and diffusion become very small, but mainly rely on screening

General dust or filter material may have charge
When they have opposite charge, electrostatic attraction appears, which improves the dust filtering efficiency, but makes it difficult to remove the dust
People have been experimenting with the method of electrifying filter cloth or dust to strengthen the electrostatic effect, so as to improve the dust filtering efficiency of particles
Gravity works only on quite large particles
Inertial collision, interception and diffusion should increase with the decrease of fiber diameter and pore of filter material
Therefore, the finer and denser the fiber of filter material, the better the dust filtering effect
