The bag filter is a dry dust filter device. It is suitable for capturing fine, dry, non-fibrous dust. Filter bag is made of textile filter cloth or non-woven felt, the use of fiber fabric filtration effect to filter the dust-containing gas, when the dust-containing gas into the bag filter, the large particles, the proportion of heavy dust, due to the action of gravity settle down, fall into the ash hopper, containing finer dust gas in the filter material when the dust is retained, so that the gas is purified.

The bag dust removal system is based on different dust properties using different filter materials to intercept and retain the dust in the dust-containing gas, and uses collision, diffusion, static electricity, sedimentation and other functions to purify the dust-containing air, and at the same time adopts ash cleaning methods such as pulse spray fisherman. Remove the dust adhered to the surface of the filter material and restore the filtration capacity again, and there is no shutdown during ash cleaning, which does not affect production. It has the advantages of high dust removal efficiency (dust removal efficiency 99.5, dust emission concentration <80mg/m3), wide adaptation range, no secondary pollution and convenient maintenance. The main body of the dust collector adopts a standard module combination mechanism, which can flexibly increase the processing air volume according to the needs of use. The original entity does not need to be changed. It has the advanced and advanced nature of the future development of the applicable user unit.
