The steel slag bag filter includes air intake, air duct, air duct slanting partition board, filter bag and ash bucket. The dust collector is also equipped with a flow guide plate and an inverted "V" shaped plate. The diversion plate is located in the middle and lower part of the air duct. The inverted "V" shaped plate is located at the bottom of the duct, and the lower end of the diversion plate and the inverted "V" shape board and the ash bucket rank. Then, the upper end of the deflector is connected with the dust bag pocket chamber. One side of the air duct inclined baffle is directly contacted with the flue gas and is coated with a quartz abrasive wear resistant layer. Compared with the prior art, the utility model has the advantages of simple and scientific structure and long service life.
A group of relative side walls of the steel slag bag type dust collector box are provided with air intake and air outlet. The air outlet is connected with the suction port of the blower, and a filter bag is arranged in the longitudinal direction of the box. The box is in the same row and the adjacent box is connected to the middle of the wall. The filter bag has a different aperture in each box, and the air inlet is different from the intake port. The pore diameter of the side to outlet side decreases in turn, and the particles in the steel slag dust are separated gradually and the separation efficiency is high.
Advantages of steel slag bag type dust collector
Usually, when the temperature of the flue gas is below 120 degrees C and the filter material is resistant to acid and durability, the pet flannelette and polyester needled felt are often selected. In the treatment of high temperature smoke (<250 C), the main selection of graphitized glass cloth; in some special cases, the selection of carbon fiber filter material and so on. Under the condition of needing coal and iron, anti explosion and anti static treatment is also needed.
Dedusting effect of steel slag bag type dust collector
The dedusting effect of steel slag bag filter is related to many factors, but mainly depends on filter material. The filter material of bag filter is cloth or felt woven from synthetic fiber, natural fiber or glass fiber. The cloth or felt should be stitched into a cylinder or flat filter bag as needed. According to the nature of flue gas, filter material suitable for application conditions is selected.
