Pulse Bag Filter

The gas purification method of the pulse bag filter is external filtration. The dust-containing gas enters the filter room of each unit through the draft tube. Because the bottom of the filter bag is designed with sufficient and reasonable vertical distance from the top of the air inlet, the airflow passes through the appropriate diversion And the natural flow direction distribution to achieve uniform air distribution in the entire filter room. The particulate dust in the dust-containing gas is separated by natural sedimentation and directly falls into the ash hopper. The rest of the dust is guided by the diversion system and enters the filter area of the middle box with the airflow. Adsorbed on the outer surface of the filter bag. The filtered clean gas is discharged through the filter bag through the upper box and the exhaust pipe.

The pulse bag filter uses compressed air to blow and clean the ash, and the ash removal mechanism is composed of an air bag, a blow pipe and an electromagnetic pulse control valve. A blowing pipe is installed at the top of the outlet of each row of filter bags in the filter chamber. The lower side of the blowing pipe is opposite to the middle of the filter bag with a blowing port. Each blowing pipe is equipped with a pulse valve and communicates with the compressed air bag. When cleaning the ash, the solenoid valve opens the pulse valve, and the compressed air is sprayed by the ash cleaning control device (differential pressure or timing, manual control) to open the electromagnetic pulse injection according to the set program, and the compressed gas passes through each pulse valve in sequence in a short time. The nozzle on the blowing pipe induces air several times the amount of injected air into the filter bag, forming an air wave, causing the filter bag to produce rapid expansion and shock vibration from the bag mouth to the bottom, resulting in a strong dust removal effect and shaking off the filter bag On the dust.

Pulse bag filter Uses compressed air as the driving force for dust removal, the compressed air is released in an instant by using the pulse blowing mechanism to induce several times the secondary air to be injected into the filter bag at a high speed, causing the filter bag to inflate sharply, relying on impact vibration and reverse airflow to clean the dust Bag filter.
