Based on the advanced technology abroad and combined with the practical application in our country, the cartridge filter has been improved and perfected continuously. The utility model has the advantages of simple structure, small volume, saving land area, convenient maintenance, long service life and high dust removal efficiency of 99.9% . It can be used as a collector of fine dust, also suitable for all kinds of conditions of division filtration, can solve the ultra-fine, wet, fibrous filter material of the surface dust, the removal rate of more than 95% . The utility model has the advantages of simple operation, continuous dust cleaning, stable resistance, high filtering speed, no internal moving parts, simple design, etc. . High dust removal efficiency, can capture more than 0.1 um of dust, so that dust-containing gas purification to 15 mg/m ~ 3 or even less. With less subsidiary equipment and less investment, the technical requirement is not as high as that of electrostatic precipitator. It can capture the dust which is difficult to be recovered by electrostatic precipitator, and to some extent, it can collect nitrides, sulfides and other compounds. Good adaptability to load change, especially suitable for capturing fine and dry dust, the collected dust is easy to handle and recycle. The bag filter has a higher safety when it collects gas with explosion hazard or spark dust.
