Dust filter filter bag

fiber

The working principle of bag filter is that the dusty air flow enters the cylindrical filter bag from the lower orifice plate. When passing through the pores of the filter material, the dust is trapped on the filter material, and the clean gas passing through the filter material is discharged from the outlet. The dust deposited on the filter material can fall off from the surface of the filter material and fall into the ash hopper under the action of mechanical vibration. Working principle: When the flue gas passes through the bag filter, the filter material fiber screens, intercepts, inertia, diffusion, adhesion, static electricity and weight the dust is kept on the surface of the filter bag to achieve the separation of dust and gas, and to achieve the purpose of dust removal and purification of flue gas. Flue gas into the bag dust catcher, interception, deposition of dust filter bag surface, when the dust layer after reaching a certain thickness, the resistance of the filter bag after rising, permeability decline, through the ash removal device at this time the settlement of powder layer peeling, restore the resistance of the filter bag, so the bag filter is a kind of periodic collect dust and soot cleaning work process, different types of soot cleaning bag filter structure and a different way.
