The pulse bag filter is a bag filter that is cleaned by the pulse cleaning method. The cleaning system of the pulse bag filter is composed of a pulse valve, a blow tube, an air bag, and an impulse control instrument. With cylinders. One end of the pulse valve is connected to the compressed air bag, the other end is connected to the blow tube, the back valve of the pulse valve is connected to the control valve, and the pulse controller controls the opening of the control valve and the pulse valve. When the controller has no signal output, the exhaust valve of the control valve is closed and the pulse valve nozzle is closed. When the controller sends a signal, the control valve exhaust port is opened and the pressure of the pulse valve back pressure is reduced. The pressure difference occurs between the two sides of the diaphragm. The diaphragm is displaced due to the differential pressure. The pulse valve blows open. At this moment, the compressed air is discharged from the air bag through the pulse valve through the orifice of the blow pipe (the gas emitted from the blow pipe). For a wind). When the high-speed airflow induces several times of the ambient air entering the filter bag through the venturi inducer, the instant pressure in the filter bag causes a positive pressure to achieve pulse cleaning.
