The gas purification method of the low-pressure pulse bag filter is external filtering. Dust-containing gas enters the filtering room of each unit through the diversion tube. Because the vertical distance between the bottom of the filter bag and the upper inlet of the air inlet is sufficient and reasonable, the air flow can be appropriately guided. And natural flow direction distribution, to achieve uniform distribution of air throughout the filter room, the particulate dust in the dust-containing gas is separated by natural sedimentation and directly falls into the ash hopper. The remaining dust is guided by the diversion system and enters the middle box filtering area with the airflow. Adsorbed on the outer surface of the filter bag. The filtered clean gas passes through the filter bag and is discharged through the upper box and the exhaust pipe.
Bag dust collector advantages
高 Dust removal efficiency is high, generally above 99%, and the dust concentration of the gas at the outlet of the dust collector is within tens of mg / m3, which has a higher classification efficiency for fine dust with a submicron particle size.
⑵The range of processing air volume is wide, the small one is only 1min to several m3, and the large one can reach tens of thousands of m3, which can be used for dust removal of flue gas from industrial furnaces and reduce the emission of atmospheric pollutants.
(3) Simple structure and convenient maintenance operation.
⑷On the premise of ensuring the same high dust removal efficiency, the cost is lower than that of the electric dust collector.
⑸ When using high-temperature-resistant filter materials such as glass fiber, polytetrafluoroethylene, and P84, it can operate under high temperature conditions above 200 ° C.
⑹Insensitive to the characteristics of dust, not affected by dust and resistance.
