Pulse Jet Bag Dust Collector Working Principle

The pulse bag dust collector consists of parts such as the ash hopper, upper, middle, and lower cabinets, which are divided into separate compartments. During operation, dusty gas enters the ash hopper through the inlet duct, with coarse dust particles falling directly to the bottom of the hopper. Fine dust particles are carried upwards by the gas flow into the middle and lower cabinets, accumulating on the outer surface of the filter bags. The filtered gas then enters the upper cabinet to the clean gas manifold-exhaust duct, and is expelled into the atmosphere by the exhaust fan. The cleaning process involves first cutting off the clean gas outlet duct of the compartment, causing the bags to be in a state without gas flow (compartment stop airflow cleaning). Then, the pulse valve is opened to use compressed air for pulse-jet cleaning, with the valve closure time sufficient for the dust particles stripped from the bags during the jet to settle in the hopper, preventing the dust from re-attaching to the surface of adjacent bags. The filter bags are cleaned, and programmable controllers automatically control the exhaust valve, pulse valve, and ash discharge valve, etc.
