Air box pulse bag-type dust collector

1、 Introduction to Airbox Pulse Bag Filter

The air-box pulse bag-type dust collector is a large pulse bag-type dust collector manufactured by Parkway Technology. The dust collector combines the advantages of various bag-type dust collector such as chambered reverse blowing bag-type dust collector and pulse jet bag-type dust collector. The large electromagnetic pulse valve is used to filter the dust and gas by chambered so as to realize dust removal by pulse jet. It has many advantages such as large air volume, strong dust removal capacity, good dust removal effect, low emission concentration and long service life.

The air-box pulse bag-type dust collector can not only purify the general dust-containing gas, but also handle the high concentration gas with the inlet concentration up to 1300mg/Nm ³. It becomes the classic finished powder recovery equipment matched with O-Sepa powder concentrator and vertical mill, and is widely used in the large powder processing industry.

3、 Operating principle of air-box pulse bag-type dust collector

When the dust-containing gas enters the dust collector from the air inlet flue, a part of coarse dust particles fall into the dust hopper due to inertia, collision, natural sedimentation and flue wall blocking. Most of the dust sinks after being filled with the flue with air flow, and enters from the bottom of each dust removal room after being evenly distributed by the air distribution system. Due to the blocking of dust removal filter materials, friction electrostatic adsorption between the dust and other effects, the dust is retained on the outer surface of the filter bag, and is gradually covered and overlapped to form a dust layer, further improving the filtration capacity of the filter bag for subsequent dust.

Under the guidance of the air flow of the induced draft fan, the dust gas is purified by the filter bag, enters the air purification chamber box from the inside of the filter bag, and is discharged into the atmosphere through the valve plate hole and air outlet to achieve the purpose of dust removal.

With the continuous filtration process, the dust layer on the surface of the filter bag is gradually thickened, and the filtration resistance of the dust removal equipment is increased. When the resistance reaches the preset value, the ash removal control system sends a signal for ash removal. At this time, the lifting cylinder is opened, the valve plate hole is closed, the entire dust removal chamber is isolated, and the pulse controller guides the electromagnetic pulse valve for soot blowing. When the dust removal is completed, the lifting cylinder retracts, the lifting valve opens again, and the dust removal room enters the filtration working state again. Each dedusting room is conducted in turn to realize independent filtration and ash removal.

The dedusting control system of pulse-box bag-type dust collector of Parkway Technology has two control modes: timing and fixed resistance, which can be flexibly selected according toactual production conditions.
