1. Filtration principle: Dust-laden gas enters from the air inlet, and when passing through the ash hopper, part of the large particle dust in the gas is separated by inertial force and falls directly into the bottom of the ash hopper. The dust-laden gas enters the upper box after passing through the ash hopper, and then is discharged from the air outlet.
2. Cleaning principle: With the prolongation of filtration time, the dust layer on the filter bag continues to accumulate, and the resistance of the dust removal equipment continues to rise. When the resistance of the equipment rises to the set value, the cleaning setting starts to clean the dust. First, a sub-chamber lift valve is closed to cut off the filtered airflow, and then the solenoid valve is opened, and the compressed air rapidly expands in the upper box in a very short time, pouring into the filter bag, causing the bag to expand and deform to generate vibration, and in the reverse airflow Under the action of scouring, the dust attached to the surface of the filter bag is peeled off into the ash hopper. After the cleaning is completed, the electromagnetic pulse valve is closed, the poppet valve is opened, and the chamber returns to the filtering state. The cleaning of each chamber is carried out in sequence, and a cleaning cycle starts from the cleaning of the first chamber to the beginning of the next cleaning.
3. Dust collection: The dust intercepted by filtration and ash cleaning will fall into the ash hopper, and then be discharged centrally from the ash hopper mouth.
