The dust-containing gas enters the dust bucket from the dust precipitator air intake unit, and under the guide of the dust trap, the dust of the big particles is separated and falls directly into the dust bucket, while the fine powder dust enters the central box evenly and adsorbs to the outer surface of the filter bag. The clean gas enters the upper box through the filter bag, the upper box exhaust pipe is discharged into the atmosphere, and the dust adsoption on the surface of the filter bag increase as the filter bag. The air permeability of the filter bag decreases, so that the resistance of the filter bag increases, when the resistance reaches a certain value, the pulse controller signals, turns on the eletromanetic pulse valve, so that the compressed air in the air bag is sprayed into the corresponding Vem tube by the nozzle holes, and induces the air around the filter bag, which is several times the wind speed of the air flow through the tube, to enter the filter bag contracted rapidly, so the dust accumulated on the outer wall of the filter bag was removed and the failling dust discharge system discharged.
