China Bag Type Dust Collector Industrial Dust Filter

Bag Type Dust Collector Industrial Dust Filter
Dust catcher makes up of frame, ash bucket, in-the-box, on-the-box, bag, frame, jet cleaning devices and PLC components such as control procedures. In -the -box is the sub-room structure, while working the gas spread out by the dust collecting duct in all ash bucket. Coarse particles directly fall into the ash bucket bottom for wind speed reducing and the ash bucket spoiler role in the collision, fine dust rose with the bag at all between the fine dust was blocked leaving the outer surface of the bag, cleaning gas clearance role with negative pressure ventilation through the bag into the mains from the body into the atmosphere, reaching the purpose of purification.
Bag Type Dust Collector Structure:

ZL series Long Bag Pulse dust collector is mainly composed of upper box, middle box, ash bucket, supporting legs, filtering bag and blowing device, ash discharging device. The features of this structure are:

1.Upper box is devided into thousands chambers. In order to realize off-line cleanign dust and maintenance, each chamber has equipment 1 lifting valve.

2.Pneumatic vent valve is controlled by air cylinder. The advantages are realiable operation, fast speed of on/off, without any leakage of air.

3.Compared with horizontal installation, the vertical installation fo pneumatic vent valve is easier during maintenance.

4.Filtering bag is self-locked and sealed on the board holes by the flexible ring on the bag. This can gurantee low emission density and easy for installation and replacement.

5.Optimized injection short tube can gurantee perfect dusting cleaning performance.

6.Safety guard and walking platform are equipped for regular maintenance.

Working Principle:
1. The dust-laden air enters the bag filter.
2. The dust /powder separates inside the bag filter chamber.
3. The air is uniformly distributed avoiding channelling while the powder is separated.
4. Initially a coat of material forms on the bags. Subsequently, the coat acts as the filtering medium.
5. The dust is accumulated on filter elements while the air passes through the filter bags from outside to inside.
6. The accumulated powder is dislodged from the bags by reverse pulsejet air intermittently.
7. The dislodged powder falls on bottom cone and is discharged through powder discharge valves.
8. The dust free air is sucked by induced draft fan and is exhausted to atmosphere.
