Pulse Dust Collector

The pulse bag dust collector consists of parts such as the ash hopper, upper, middle, and lower boxes, which are segmented into separate chambers. During operation, dust-laden gas enters the ash hopper via the inlet duct, with coarse dust particles falling directly to the bottom of the hopper. Fine dust particles are carried upward by the airflow into the middle and lower boxes, accumulating on the outer surface of the filter bags. The filtered gas then enters the upper box and flows into the clean gas collection pipe-air outlet duct, where it is exhausted into the atmosphere by the exhaust fan. The cleaning process involves first cutting off the clean gas outlet duct of the chamber, causing the bags to be in a state without air flow (chamber stop-air cleaning). Then, the pulse valve is opened to use compressed air for pulse-jet cleaning, with the valve closure time sufficient to ensure that the dust detached from the filter bags settles into the ash hopper after the jetting, preventing the dust from reattaching to the surface of adjacent bags. This ensures thorough cleaning of the filter bags and is automatically controlled by a programmable controller for the exhaust valve, pulse valve, and ash discharge valve, etc.
