Background
Along with the improvement of living standard of people, the requirement on air quality is higher and higher, and the dust remover is widely applied to industries such as electric power, chemical engineering and the like. After the filter material in the dust collector is used for a period of time, a layer of dust is accumulated on the surface of the filter bag due to the effects of screening, collision, detention, diffusion, static electricity and the like, 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. In addition, the air volume of the dust removal system is significantly reduced due to the excessively high resistance of the dust remover. Therefore, the dust is removed in time after the resistance of the dust remover reaches a certain value. The initial layer cannot be damaged during ash removal so as to avoid efficiency reduction
At present, the structure of the prior bag-type dust collector is inconvenient to dismantle and clean, and the dust can not be thoroughly cleaned when the dust in the bag-type dust collector is cleaned. Therefore, we improve this and propose a dust recycling mechanism and a filter cartridge dust remover.
