Gas box pulse bag filter is a type of gas box dust collector. Its working principle is that the dust containing gas enters the dust collector through the inlet, and larger particles of dust directly fall into the ash hopper. The gas containing particulate dust passes through the filter bag, and the dust is retained on the outer surface of the filter bag, while the gas is purified and discharged into the atmosphere by the induced draft fan.
As the filtration process continues, the amount of dust adhering to the outer surface of the filter bag increases, and the operating resistance of the dust collector increases. The conversion valve of a certain filtration unit closes, and the filtration unit stops working. Compressed air is blown back into the filtration unit to blow off the dust on the outer surface of the filter bag. Then, the conversion valve plate opens, and the filtration unit resumes operation, and the cleaning of dust shifts to the next filtration unit.
The entire dust cleaning process is carried out alternately by each filtering unit.
The gas box pulse bag filter integrates the advantages of chamber back blowing and spray pulse bag filter, overcoming the shortcomings of insufficient cleaning ability of chamber back blowing and simultaneous spraying and filtering, expanding the application range of bag filter. It can not only purify general dusty gases, but also process gases with an inlet concentration of 1300g/m ³. It has become a finished product recovery equipment for O-sepa powder selection machine and vertical mill, improving the dust removal efficiency and progressiveness of the dust collector, extending the service life of the filter bag, and becoming an ideal product for enterprises to protect the environment.
The main body of the pneumatic pulse bag filter is divided into several box areas, with 32, 64, 96, and 128 filter bags per box. Compared with ordinary gas box pulse dust collectors, this device has a small volume, light weight, compact structure, good shell strength, and does not require ash unloading and conveying equipment. Therefore, it has low operating power consumption and low maintenance. It has the characteristics of low investment, low operating costs, and limited installation space for local dust source exhaust gas treatment.
The above are the advantages and working principles of the pneumatic pulse bag filter. The pneumatic pulse bag filter is just one type of pneumatic dust collector.
