GMC type pulse bag filter

GMC type pulse bag filter; Performance characteristics:

1. It consists of ash hopper, upper box, middle box, cloth bag, ash cleaning and blowing device, and other parts.

2. By using downward air intake, it has a pre dust collection effect on the dusty gas, avoiding direct flushing of the bag by the dusty gas, reducing the dust concentration of the dusty gas, and extending the life of the filter bag and pulse solenoid valve.

3. The sealing materials for dust collectors are mainly based on actual reports.

4. The ash cleaning spray pipe adopts an elongated type to keep the pulse solenoid valve away from high-temperature flue gas and avoid damage to the valve disc of the pulse solenoid valve due to high temperature.

5. The filter bag adopts actual reports as the main filter bag to handle the temperature and humidity of the flue gas; Lt; 250 ℃.

6. The filter bag mouth adopts an elastic expansion ring, which has strong sealing and excellent firmness.

7. The filter bag skeleton adopts a circular shape, which reduces the friction between the filter bag and the skeleton, prolongs the service life of the filter bag, and facilitates the unloading of the bag.

8. Adopting the upper bag extraction method, when changing bags, open the top cover door and extract the skeleton to replace the bag. The actual effect mainly depends on the operating conditions of bag replacement.

9. The dust cleaning control adopts timed control. According to the set time, every cleaning cycle, each row of filter bags is cleaned one by one.

When the GMC type pulse bag filter is working, high-temperature flue gas flows into the ash hopper through the air inlet on the ash hopper. Due to the gravity settling effect, coarse dust particles directly fall into the bottom of the ash hopper, playing a role in pre dust collection. At the same time, the airflow speed slows down, and slight dust enters the middle box with the airflow turning upwards. The dust is filtered and retained by the high-temperature filter bag, and accumulates on the outer surface of the filter bag. The filtered gas enters the upper box through the filter bag to the air outlet, and is discharged to the atmosphere through the induced draft fan. The dust accumulated on the outer wall of the filter bag continues to increase. When the set time is reached, the pulse controller sequentially triggers the opening of the pulse solenoid valve at intervals, causing the compressed air in the compressed air bag to pulse blow and clean the dust of each row of filter bags through the blowing pipe, causing the filter bags to rapidly expand and shake off the dust accumulated on the outer wall of the filter bag in an instant. The dust peeled off from the filter bag settles in the ash hopper and is discharged through the ash discharge gate valve.
