Background

The bag type dust collector is a dry type dust filtering device. The dust collector is suitable for collecting fine, dry and non-fibrous dust, and has the working principle that dust-containing airflow enters a cylindrical filter bag from a lower hole plate, the dust is collected on the filter bag when the dust passes through the holes of the filter bag, and clean gas penetrating through the filter bag is discharged from a discharge port. The dust deposited on the filter bag can fall off from the surface of the filter bag under the action of mechanical vibration and fall into the dust hopper.

In the process of implementing the invention, the inventor finds that at least the following problems exist in the technology: after the filter bag is used for a period of time, due to the effects of screening, collision, detention, diffusion, static electricity and the like, a layer of dust is accumulated on the surface of the filter bag, the layer of dust is called as a primary layer, the primary layer forms a main filter layer of the filter bag in the later movement process, and the filter material with larger meshes can also obtain higher filtering efficiency under the action of the primary layer. However, as the dust accumulates on the surface of the filter material, the efficiency and resistance of the dust collector increase accordingly, and when the pressure difference between the two sides of the filter material is large, some fine dust particles attached to the filter material are extruded, so that the efficiency of the dust collector is reduced. In addition, the air volume of the dust removal system is significantly reduced due to the excessively high resistance of the dust remover. Therefore, the dust is removed in time after the resistance of the dust remover reaches a certain value. However, at present, the dust removal mainly adopts the modes of gas dust removal, mechanical vibration dust removal, manual vibration and the like, so that the initial layer on the filter bag is easy to damage, and the subsequent filtering efficiency of the filter bag is influenced.
