For wet gas in the selection of filter bag matters needing attention


(1) the wet gas makes the dust collected on the surface of the filter bag wetting bond, especially for the water-absorbing, dehumidifying and wetting dust, will cause the paste bag. For this, should choose the filter bag with smooth surface such as polyamide fiber and glass fiber, long fiber is easy to clear ash, and appropriate to filter bag use silicon oil, carbon fluoride resin for impregnation treatment, or use acrylic acid, polytetrafluoroethylene and other materials on the surface of the filter bag coating treatment. Plastic - fired board and film - coated materials have excellent properties of moisture resistance and dust - cleaning.


(2) when high temperature and high humidity exist at the same time, the temperature resistance of the filter bag will be affected, especially for materials with poor hydrolysis stability such as polyamide, polyester, amide, should be avoided as far as possible.


(3) for wet gas in the dust removal bag design appropriate use of circular filter bag, try not to use the shape of complex, very compact layout of the flat filter bag and diamond filter bag (except plastic burning board).


(4) the dust gas inlet temperature of the dust collector should be 10 ~ 30 ℃ higher than the dew-point temperature of the gas.
