After the dust-laden gas enters the dust hopper of the multi cyclone separator, due to the sudden expansion of the airflow section and the action of the airflow distribution plate, part of the coarse particles in the airflow settle in the ash hopper under the action of dynamic and inertial forces; dust particles with fine particle size and small density enter After the dust filter chamber, the dust is deposited on the surface of the filter material through the combined effect of Brownian diffusion and sieving, and the purified gas enters the clean air chamber and is discharged by the exhaust pipe through the fan. The resistance of the cartridge type dust collector increases with the increase of the thickness of the dust layer on the surface of the filter material. When the resistance reaches a certain value, cleaning is carried out. At this time, the PLC program controls the opening and closing of the pulse valve. First, the lift valve of one sub-chamber is closed to cut off the filtered air flow, and then the electromagnetic pulse valve is opened, and the compressed air rapidly expands in the upper box in a short period of time, pouring into the filter cartridge, making the filter cartridge The expansion deformation produces vibration, and under the action of reverse airflow, the dust attached to the outer surface of the filter bag is peeled off and falls into the ash hopper.
After the multi cyclone separator is cleaned, 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. The falling dust falls into the ash hopper and is discharged through the ash-removing valve. In this process, the filter cartridge must be replaced and cleaned regularly to ensure the filtering effect and accuracy, because in the filtering process, in addition to being blocked, some of the dust will be deposited on the surface of the filter material, increasing the resistance, so the general correct replacement Time is three to five months!
