Dust discharge method

The pulse dust collector is mainly composed of upper, middle and lower three boxes and platforms, electrical control equipment, ash hopper, ladder, dragon frame, pulse valve, gas storage tank, screw conveyor, air compressor, ash unloading valve, etc. The process has three stages: filtering, cleaning and conveying. The pulse bag filter uses an external filter structure, that is, when the dust-containing gas enters each filter unit, it can directly fall into the ash hopper under the action of inertia and gravity according to the different properties of the dust. The fine dust particles gradually enter the filter room as the airflow turns. The dust is filtered by the dust cake on the surface of the filter bag, and the fine dust accumulates on the surface of the filter bag. Only the clean gas can enter the upper box from the inside of the filter bag. The exhaust duct, which is gathered into the clean air collecting pipe, is discharged into the atmosphere by the fan, so as to truly restore the freshness of nature.
