Single Pulse Bag Filter

Single-pulse bag filter is widely used in mining and mining, electric furnace smelting, machinery manufacturing, chemical products, cement, building materials, grain processing and other industrial and mining enterprises warehouse top, bottom, belt transmission and local dust source dust. It has the advantages of small size, large air volume, compact structure and easy use. The structure is mainly composed of a fan, a box, an ash discharging device, a control system and the like. All of them are placed in a box made of welded steel plates, baked and rust-proof, beautiful in appearance, scientific in structure, and easy to operate. The lower flange of the unit is directly coupled to dust collection equipment such as the top of the warehouse, silo, and belt transportation to remove dust in situ, and the dust is directly recovered.

working principle

Dust-laden gas enters the box through the air inlet, and the purified gas filtered by the filter bag is directly discharged by the fan. With the increase of filtration time, more and more dust accumulates on the filter bag, which increases the resistance of the filter bag, resulting in a gradual decrease in the processing air volume. For normal operation, the filter bag must be cleaned in order to control the resistance within a certain range. When the ash is cleaned, each control valve is triggered by the pulse control device to open the pulse valve. The compressed air in the air bag is injected into the filter bag through the pulse valve to the holes of the injection pipe. The filter bag instantaneously expands rapidly and the product is attached to the filter. The dust on the surface of the bag falls off and the filter bag is regenerated. Cleared dust falls and ash buckets are discharged through the drain valve. In this way, the dust accumulated on the filter bag is periodically pulsed and cleaned so that the purified gas passes normally.
