Pleated filter bag
Pleated filter bag, dust collector can directly replace existing circle (oval) bags and keel without having to do a structural transformation of the main device according to system design and needs, normally 50-150% increase the filter area. Significantly reduce system pressure thereby improving overall system performance and bag life. A significant reduction in cleaning frequency or extend cleaning intervals, compared with ordinary bag pulse cleaning efficiency (same media) because of its special structure significantly improved, effectively increasing the bag spacing between bags of air rising rate of decline, greatly improving the Online cleaning effect. Specially designed bag / keel is greatly reduced due to fatigue damage caused by pulse jet and intermittent emissions. Keel no lateral support ring and effective contact area, to completely avoid the direct impact on the sack. Pressing need to increase the filter area while shortening the length of the bag system operation optimization, greatly reducing the amount of compressed air and air compressor, the load pulse valve ,, fan load is greatly reduced, significantly reduced energy consumption .. professional R & D in manufacturing corrugations and corrugations type bag type bag filter. Filter area can be achieved under the same circumstances 160-200% cylindrical bag, the equipment running resistance can be reduced to 600 to 800Pa, condition emission concentration can reach 10mg / m³ or less.
1. With low air-to cloth rate, sharply reduce the operating resistance.
2. Filter area is 1.5-2 times than normal round bag
3. Speed of airflow go down, easy for dust settling
4. Improve the compressor air pulse
5. Extend the pulse cycle
6. Reduce fatigue damage, increase the bag life
7. The composite cost reduced
1. Need to increase gas flow for more capacity: dement kiln, clinker cooler, cement mill, coal mill, power plant boiler, steel company, etc.
2. High dust load: cement mill, coal mill, FGD.
3. Need more time to stick dust on filter bags: Aluminum, FGD,demercuration, absorb Dioxin.
4. Need to reduce emission (Old bag house transform, reach the emission standard).
5. Need to reduce pressure drop
6. Need to reduce pressure drop
7. Need to reduce the cost of bag house
