The intelligent automatic pulse cleaning system is composed of PLC controller, electromagnetic pulse valve, compressed air bag and other components. The compressed air inlet of the pulse valve is connected with the air bag, and the electromagnetic valve nozzle is aligned with the filter cylinder filter outlet; The solenoid valve control line is connected with the PLC controller, the action of the solenoid valve is intelligent controlled by the PLC controller, when the controller gives the action command, the pulse solenoid valve begins to act, each spray cleaning in 0.1 ~ 0.3S or so to complete, at this moment the high-pressure air from the filter cylinder exhaust port into the filter cylinder at high speed, causing a shock vibration, The dust attached to the outer surface of the filter cylinder is shaken off in the dust collection bucket. The cleaning frequency can be set intelligently by PLC controller.
