Off-Line Pulse Bag Filter SolidWorks

At present, the pulse bag dust collector dust removal method branches spray pulse blowing dust removal and air box pulse dust removal two ways. The characteristics of these two cleaning methods are as follows.

Line spray pulse blowing dust removal method: dust removal kinetic energy is large, can uniformly achieve thorough dust removal for each filter bag inside the dust collector row by row, small running resistance, longer filter bags (can exceed 6m) and large aspect ratio, small volume, small footprint and light weight. Air box pulse dust cleaning method: dust cleaning kinetic energy is larger, due to the use of one to two pulse valve to a bag chamber dust cleaning, to ensure clean dust cleaning, the bag chamber can not be too large, the filter bag can not be too long. Large air box pulse dust collector filter bag number, covers an area of large. The use of off-line cleaning method, but the negative pressure in the equipment is large, it is not easy to achieve online maintenance without stopping, changing bags.

Usually, according to the pressure of the gas source, the pulse blowing cleaning is divided into high pressure pulse blowing cleaning and low pressure pulse blowing cleaning, and the selected gas source pressure range for this project is 0.4~0.6Mpa, i.e. high pressure pulse blowing cleaning, based on the following.

???High-pressure dust cleaning is more thorough, requires less times of dust cleaning, saves high-pressure air source, brings in less external compressed air, reduces the load of dust collector tail discharge fan, thus low energy consumption and less operation cost.

???The pressure range of compressed air source used for dust collectors in cement plants is 0.4~0.6Mpa, which is convenient for unified management, etc.

???High-pressure ash cleaning induces more clean hot air after filtration with the least amount of compressed air, which is conducive to equipment anti-condensation
