The advantages of the bag filter: the dust removal efficiency is as high as 99%, and the dust concentration of the gas at the outlet of the dust collector is within 10 mg / m3, which has a higher classification efficiency for fine dust with a submicron particle size. Simple structure and easy maintenance operation. It is not sensitive to the characteristics of dust and is not affected by dust and resistance. The range of air volume to be processed is wide, reducing the emission of air pollutants. On the premise of the same high dust removal efficiency, the cost is lower than that of the electric dust collector.
Disadvantages of bag dust collectors: filter bags need to be replaced. Due to the low variety of filter materials and poor quality, the technology of sewing bags is not enough and the dust removal system causes the service life of filter bags to be short, especially at high temperatures In the case of highly corrosive flue gas, some months _ need to be replaced once, which increases the operating costs and maintenance workload, and brings inconvenience to users. The resistance is large, and cooling measures must be taken for high-temperature gases. In cold areas, the condensation of water vapor in compressed air will affect the blowing effect, so it should not be placed outdoors.
