Description

Technical Field

[0001] The utility model relates to the technical field of industrial dust removal, in particular to a bag dust collector. Background Art

[0002] The filter bag is a kind of dry dust filtering device, which is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter the dust-containing gas. When the dust-containing gas enters the bag filter, the dust with large particles and high specific gravity settles down due to the action of gravity and falls into the ash hopper. When the gas containing fine dust passes through the filter material, the dust is retained, so that the gas is purified. After the filter material has been used for a period of time, a layer of dust accumulates on the surface of the filter bag due to screening, collision, retention, diffusion, static electricity and other effects. As the dust accumulates on the surface of the filter material, the efficiency and resistance of the dust collector increase accordingly. When the pressure difference on both sides of the filter material is large, some fine dust particles attached to the filter material will be squeezed over, which reduces the efficiency of the dust collector. After a period of use, the surface of the filter bag will have a certain wear and tear, and the filter bag needs to be replaced regularly. However, the current bag-type dust collector filter bag is difficult to replace due to being fixed, and the cost is high.

[0003] Therefore, there is an urgent need for a bag filter that is easy to replace. Utility Model Content
