Qingyuan GMC Boiler Pulse Bag Dust Collector
1、 Boiler bag filterworking principle:
The GMC type high-temperature flue gas pulse bag dust collector consists of an ash hopper, a box, a filter bag, an automatic ash cleaning and blowing device, and other components. During operation, high-temperature flue gas enters the dust collector through the air inlet and first hits the inclined partition in the middle of the air inlet. The airflow then turns downwards and flows into 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 box with the airflow turning upwards. The dust is filtered and retained by the filter bag, and accumulates on the outer surface of the filter bag. The filtered clean gas enters the upper clean air chamber of the 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 or set pressure difference 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 valve.
2、 Boiler bag filterPerformance characteristics:
1Boiler bag filterThe air inlet and outlet are integrated and separated by inclined partitions, ensuring uniform airflow distribution and pre collecting dust and blocking sparks for dusty gases. This avoids direct erosion of the bag by dust, reduces the dust concentration of the dusty gas, and extends the lifespan of the dust removal bag and electromagnetic pulse valve.
2. The dust removal bag adopts a cloth bag with a working temperature of less than 200 ℃.
3. The sealing materials for the dust collector are all made of _ material.
4. The ash cleaning spray pipe adopts an elongated type to keep the pulse electromagnetic pulse valve away from high-temperature flue gas and avoid damage to the valve plate of the pulse electromagnetic valve due to high temperature.
5. The bag mouth of the dust removal bag adopts an elastic expansion ring, which has good sealing performance and is firm and reliable.
6. The framework of the dust collector adopts a circular shape, which reduces the friction between the filter bag and the framework, prolongs the service life of the filter bag, and facilitates the unloading of the bag.
7. Adopting the upper bag extraction method, when changing the bag, open the top cover door and extract the skeleton to replace the bag. This is the operating condition for changing the bag.
8. The dust cleaning control adopts timed, pressure controlled, and manual control. Every cleaning cycle, each row of filter bags is cleaned one by one.
9. The dust collector is wrapped with rock wool insulation layer to prevent condensation inside the dust collector.
10. Install a bypass valve at the air inlet to prevent damage to the dust bag from high temperatures.
11. Install high temperature alarm device and filter bag leak detection device.
