With the national emphasis on environmental protection and treatment of atmospheric pollutants and the standard requirements, bag type dust collectors have been widely used in various industries. The bag type dust collector is a dry dust filtering component, after the filter material is used for a period of time, due to the effects of screening, collision, detention, diffusion, static electricity and the like, a layer of dust is accumulated on the surface of the filter bag, the layer of dust is called as a primary layer, in the later movement process, the primary layer becomes a main filter layer of the filter material, and the filter material with larger meshes can obtain higher filtering efficiency by virtue of the action of the primary layer. Along with the accumulation of dust on the surface of the filter material, the efficiency and the resistance of the dust remover are correspondingly increased, and when the pressure difference between two sides of the filter material is large, some fine dust particles attached to the filter material are extruded, so that the efficiency of the dust remover is reduced.
