Description

A kind of back blowing dust cleaning device for filter bag dust collector

technical field

The utility model relates to the technical field of dust collectors, in particular to a reverse blowing dust cleaning device for a filter bag dust collector.

Background technique

The bag filter is a dry dust filter device. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, and the dust-containing gas is filtered by the filtering effect of the fiber fabric. After the filter, the dust with large particles and heavy specific gravity settles down due to the action of gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is blocked and the gas is purified.

The filter bag filter needs to clean the dust on the surface of the filter bag after removing the dust. The existing cleaning method is to expand and retract the filter bag through back blowing, so that the dust on the surface falls off. The existing cleaning method cannot make the surface of the filter bag fall. The dust is cleaned very cleanly, which affects the subsequent dust removal.
