Background

The bag type dust collector is a dry type dust filtering device. It is suitable for trapping fine, dry, non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, the dust-containing gas is filtered by the filtering action of the fiber fabric, after the dust-containing gas enters the bag type dust collector, dust with large particles and large specific gravity falls into the dust hopper due to the sedimentation of the gravity, and when the gas containing fine dust passes through the filter material, the dust is blocked, so that the gas is purified. 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.
