1. According to the shape of the cross section of the dust filter bag, it can be divided into: flat bags (trapezoidal and flat) and round bags (cylindrical).
2. According to the air inlet and outlet mode, it can be divided into: bottom air inlet and top air outlet, top air inlet and bottom air outlet, and direct current type (limited to plate-shaped flat bags).
3. According to the filtering mode of the dust filter bag, it can be divided into: external filtering type and internal filtering type.
4. According to the temperature tolerance of dust filter bags, they are divided into: high temperature type, medium temperature type, and normal temperature type. 5. Application fields Application fields: iron and steel mills, ferroalloy plants, refractory plants, foundries, power plants, cement plants, chemical plants, grain processing plants, carbon black plants, aluminum plants, etc.
(1) Low temperature type, suitable for bag dust collectors at local dust points such as raw material mills, cement mills, top and bottom of silos, etc., and when used under high humidity conditions, the surface needs to be treated with oil-repellent and waterproof treatment agents;
(2) Normal and high temperature type, suitable for bag dust collectors for high temperature exhaust gas treatment such as cement vertical kilns, rotary kiln tails, coolers, dryers, etc., and when used under high temperature and high humidity conditions, the surface needs to be treated with oil-repellent and waterproof treatment agents.
