Large bag dust collector

Large bag dust collector

Large bag filter

Working mechanism of large bag filter:

1. Filtering principle:

The dust gas from the long bag low-pressure pulse dust collector enters through the inlet. When passing through the ash hopper, some large particles of dust in the gas are separated by inertial forces and directly fall into the ash hopper. Dust and gas enter the filter bag filtration area of the box through the ash hopper, and the gas passes through the filter bag, causing dust to clog the outer surface of the filter bag. The purified gas enters the box through the filter bag port and is discharged from the air outlet.

2. Dust cleaning principle:

As the filtration time prolongs, the dust layer on the filter bag continues to accumulate, and the resistance of the dust removal equipment continues to rise. When the resistance of the equipment rises to the set value, the dust removal device begins to remove dust. The electromagnetic pulse valve opens, and the compressed air expands appropriately in a short period of time, flowing into the filter bag, causing the filter bag to expand, deform, and vibrate. Under the action of reverse airflow scouring, the dust attached to the outer surface of the filter bag is peeled off and falls into the ash hopper. After cleaning the dust, the electromagnetic pulse valve is closed and the indoor filter returns to normal. Each room is cleaned in sequence, from the room with good sales to the next cleaning, which is a cleaning cycle.

3. Dust collection:

The dust cut off by the filtering and ash removal work falls into the ash hopper, which is discharged through the plug valve and the pneumatic dust control valve. Then it is transported centrally by a conveyor.

Characteristics of Large Long Bag Low Voltage Offline Pulse Dust Removal Equipment

By adopting pulse jet technology, the problems of low jet intensity, excellent performance, and thorough dust cleaning of the anti blowing machine have been solved.

Excellent intake manifold and ash hopper diversion technology ensure even distribution of air flow in the compartments and smooth ash discharge.

The pulse valve and gas storage bag have a large capacity to meet the different blowing needs of users.

4. The filter bag is easy to load in multiple areas, has good sealing performance, and enables external bag replacement

5 adopts an automated bag cage production line to meet the needs of users for various structures (circular, octagonal, etc.). ）Good quality and beautiful appearance.

6. Equipped with high-performance electromagnetic pulse valves, the lifespan of the vulnerable film exceeds 100 × 10 times.

7 adopts excellent PLC programmable controller, and can add alarm control of temperature, material level and other sensors according to different user needs.

Maintain large long bag low-pressure offline pulse dust collector

1. Dust collectors should be operated and maintained by dedicated personnel. Master the performance and structure of the dust collector, promptly address issues, and confirm the normal operation of the dust collector. The on duty personnel should record the on duty operations and related data.

2. Regularly lubricate the rotating parts.

3. Perform insulation and rainproof work on dust collectors, pipelines, and other related components.

4. Regularly check the air leakage in the gap between the upper cover of the dust collector, inspect the air leakage in the closed ash discharge valve under the dust collector, and check the air leakage at the flange connection of the pipeline to reduce air leakage.

5. The dust containing gas in the dust collector should be evenly distributed to prevent the reduction of local low temperature and condensation problems caused by the amount of gas passing through the vortex.

6. Take appropriate heating measures. Such as dust collector, ash hopper, electric heater, steam tracing device, etc. Strengthen temperature monitoring of dust collectors and dust removal systems, understand the usage conditions of bag filters, and prevent condensation.

7. If smoke and dust are found at the exhaust port, it indicates that the filter bag is leaking. During maintenance, open the upper cover room by room. If dust is found on the bag opening, it indicates that the filter bag is damaged and needs to be replaced in a timely manner or replaced with attentive service.

8. In general, the resistance of the dust collector is 1200-1500Pa, 1800Pa, and the cleaning cycle is adjusted according to the resistance to adjust the setting switch of the control cabinet.

9. The air filter of the compressed air system should be discharged regularly, and the drain valve with a lower airbag should be discharged regularly. The gas storage tank should also be regularly discharged.

10. The dedicated personnel should maintain the control valve and regularly inspect the electromagnetic pulse valve.
