Description

Pulse dust collector

Technical Field

The utility model relates to a dust removal field specifically is a pulse dust collector.

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. However, the filter bag which cannot timely clean the dust on the bag-type dust collector during working cannot clean the dust, which affects the use of the dust collector.

The pulse dust collector is a novel high-efficiency pulse dust collector improved on the basis of a bag type dust collector, integrates the advantages of various pulse blowing dust collectors with chamber back blowing, overcomes the defects of insufficient chamber dust cleaning strength, uneven distribution of inlet and outlet air and the like, and enlarges the application range. However, after the pulse is emitted by the existing pulse dust collector, the filter bag rapidly expands instantly to drop off the dust accumulated on the surface of the filter bag, but the contraction speed of the filter bag is poor, so that the dust dropping effect and the dust cleaning effect are influenced.
