1. The installation of the shot blasting machine filter bag is not correct: A. The installation process of the worker is disordered, the storage of the bag cage and the filter bag is irregular, and the filter bag or the bag cage is deformed by deformation. 2. The equipment of the shot blasting machine is made. Not fine: A, bag cage processing is rough, if there is rust, welding, burr, open welding, etc., will accelerate the mechanical wear of the filter bag;
3. The temperature of the dust-removing equipment of the shot blasting machine is unstable: A. The higher the temperature of the flue gas, the faster the chemical reaction speed, and the filter material sensitive to oxidation and other chemical reactions is easily damaged under such operating conditions. As a result, its service life is greatly reduced. B. When the dust removal equipment is in operation, the temperature must be kept above the knot. If the temperature is lower than this limit, the water vapor in the flue gas will be concentrated. The concentrated water vapor will be contaminated with dirty soot, which may cause corrosiveness. Acid dew, corrosion filter bag or paste bag, resulting in shortened filter bag life or increased resistance of dust removal equipment, which will seriously prevent the dust collector from running. C, the effect of dust removal temperature, sparks in the smoke will often burn out the filter bag
