Filter Cartridge Dust Collector
After the dust containing gas enters the dust hopper, due to the sudden expansion of the airflow section and the action of the airflow distribution plate, a part of the coarse particles in the airflow settle in the dust hopper under the action of dynamic and inertial forces.
After entering the filter chamber, the dust particles with fine particle size and small density are deposited on the surface of the filter material through brown diffusion and screening, and the purified gas enters the clean air chamber and is discharged by the exhaust pipe through the fan.
The resistance of cartridge filter increases with the increase of dust layer thickness.
Ash removal occurs when the resistance reaches a specified value.
At this time of PLC program control pulse valve opening and closing, lift valve closed, first one room will be truncated filtering flow, and then the electromagnetic pulse valve open, compressed air and a short time the case on the rapid expansion, the influx of cartridge, cartridge expansion deformation produces vibration, and under the action of reverse flow scouring, attached to the filter bag dust on the surface of the appearance, stripped fell into the hopper.
After the ash removal, the solenoid pulse valve is closed, the lifting valve is opened, and the filtration state of the chamber is restored.
Each room is carried out in turn, and the period from the first room to the next room is a cleaning period.
The dust falls into the dust hopper and is discharged by the ash discharge valve.
