Bag pulse dust collector is selected, and high temperature bag is used in the bag, which has long service life and simple maintenance. The dust removal effect is much better than the original atmospheric blowback, and the water curtain dust removal effect is poor, which will also cause secondary pollution.

Dust collector equipment refers to the equipment that separates dust from flue gas, which is called dust collector or dust collection equipment. Dust removal equipment is to use underground dust removal pipes and compressed air pipes, add certain additives to the water, and introduce wind pressure. Through special equipment, a series of technological processes such as material absorption, material mixing and foaming are completed to generate foam, which is sprayed on the dust source through the distributor and nozzle bracket assembly. Foam acts on dust through good covering, wetting and adhesion, which effectively reduces the dust concentration in the mining face, greatly improves the working environment of the mining face, improves the working efficiency of underground workers, and effectively reduces the incidence of pneumoconiosis among front-line workers.
