Technical principle: The pulse bag filter consists of an upper box, a middle box, a lower box, an ash hopper, a frame, and a pulse blowing device. During operation, dusty gas enters the ash hopper through the inlet duct, and coarse dust particles directly fall into the bottom of the ash hopper. Dust accumulates on the outer surface of the filter bag, and the filtered gas enters the upper box to the clean gas collection pipe exhaust pipe, and is discharged to the atmosphere through the exhaust fan. The dust cleaning process involves first cutting off the clean air outlet duct of the room, so that the bag in the room is in a state of no airflow passing through (stopping the air and cleaning the dust in each room).

Then, the pulse valve is opened and compressed air is used for pulse blowing to clean the dust. The shut-off valve is closed for a sufficient time to ensure that the dust peeled off from the filter bag settles in the ash hopper after spraying, avoiding the phenomenon of dust adhering to the adjacent filter bag surface with the airflow after leaving the filter bag surface. The filter bag is cleaned, and the exhaust valve, pulse valve, and ash discharge valve are fully automatically controlled by a programmable controller. Applicable industries: Suitable for the purification of dusty gases and material recovery in metallurgy, building materials, cement, machinery, chemical, power, and light industry industries.
