Description

A bag dust collector for galvanizing industry

Technical Field

The utility model relates to the technical field of dust removal, in particular to a bag type dust collector for the galvanizing industry.

Background Art

Bag filter is a dry dust filter device used to capture 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 dust-containing gas. When the dust-containing gas enters the bag filter, the large particles and heavy dust settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, so that the gas is purified.

Existing bag dust collectors generally use compressed air to spray and clean the filter bags, but the effect is not very good. Some dust still adheres to the surface of the filter bags, thus affecting the filtering effect of the filter bags.
