●FAQ:
Q. What are the applicable industries for high-temperature dust removal filter bags?
A.1. Dust removal at the end/head of cement kiln
2. Metallurgical steel sintering machine, blast furnace gas purification
3. Waste incineration power plant
4. Dust removal of thermal power boilers
5. Chemical, coking, carbon black production
6. Asphalt mixing station
Q. What are the precautions for filter bag installation?
A.1. Ensure that the bag mouth and the flower plate are tight and leak-free
2. The frame is smooth and burr-free to avoid scratching the filter bag
3. The filter bag is hung vertically and cannot be twisted or folded
4. Perform a pulse test after installation to check the sealing
5. Avoid dust and moisture in the installation environment
Q. How to determine whether the high-temperature filter bag needs to be replaced?
A.1. The pressure difference continues to increase or suddenly decreases
2. The chimney emission concentration exceeds the standard
3. System alarm (such as the differential pressure is too high)
4. The filter bag is found to be hardened, cracked, shrunk, and deformed during maintenance
5. The filter bag becomes brittle, powdered, and the appearance is seriously damaged
