Background

A filter bag dust collector is a dry dust filter which is suitable for collecting fine, dry and non-fibrous dust. The filter screen is made of woven filter cloth or non-woven felt, the dust-containing gas is filtered by utilizing the filtering action of the fiber fabric, after the dust-containing gas enters the filter bag dust collector, the 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 screen, the dust is blocked, so that the gas is purified. For the filter screen, due to the effects of screening, collision, retention, diffusion, static electricity and the like, a layer of dust is gathered on the surface area of the filter screen, and the efficiency of the dust collector is reduced along with the accumulation of the dust on the surface of the filter screen. In addition, the air volume of the dust removal system is significantly reduced due to the excessively high resistance of the dust collector. Therefore, after the dust on the surface of the filter screen reaches a certain value, the dust is removed in time. In order to remove dust on the surface of a filter screen, an existing filter screen dust collector generally adopts a pulse back blowing system, high-pressure gas is periodically sprayed into the filter screen, and the dust attached to the surface of the filter screen is shaken off.
