Steel slag bag filter

The steel slag bag type dust collector includes an air inlet, an air duct, an inclined partition of the air duct, a filter bag, and an ash hopper. The feature is that the dust collector is further equipped with a guide plate and an inverted "V" shaped plate. The guide plate is located in the middle and lower part of the air duct, and the inverted "V" shaped plate is located directly below the air duct. The lower end of the guide plate and the inverted "V" shaped plate is connected to the ash hopper, and the upper end of the guide plate is connected to the dust collector bag chamber. The side of the inclined baffle of the air duct that directly contacts the flue gas is coated with a layer of quartz diamond sand. Compared to existing technologies, this utility model has the advantages of simple structure and long service life.

A set of opposite side walls of the steel slag bag filter box are respectively equipped with inlet and outlet ports. The outlet port is connected to the exhaust port of the blower, and a filter bag is longitudinally arranged inside the box; The box body is arranged in series with multiple units in the same row, and a ventilation hole is set in the middle of the connecting wall of adjacent boxes; The pore size of the filter bag is different in each box, and the pore size decreases sequentially from the inlet side to the outlet side, gradually separating and separating the particles in the steel slag dust.

Dust removal effect of steel slag bag filter:

The dust removal effect of steel slag bag filter is related to various factors, but mainly depends on the filter material. The filter material of a bag filter is a cloth or felt woven from synthetic fibers, fibers, or glass fibers. Sew the fabric or felt into cylindrical or flat filter bags as needed. Select filter media suitable for application conditions based on the properties of the flue gas.

Advantages of steel slag bag filter:

Usually, when the flue gas temperature is below 120 ℃ and the filter material is required to have acid resistance and properties, polyester velvet cloth and polyester needle punched felt are often used; When dealing with high-temperature flue gas (<250 ℃), graphite glass fiber cloth is mainly used; In some cases, carbon fiber filter materials may be used. When coal, iron, and stone are needed for processing, the filter material for dust removal bags needs to be selected as silk.
