Carbon fiber electric heater

The working principle of bag filter and bag filter is that the dusty flue gas passes through the filter material, and the dust particles are filtered. The filter material mainly catches the coarse dust by inertial collision, and the fine dust by diffusion and screening. The dust layer of the filter material also has a definite filtering effect

the dust removal effect of bag filter is related to many factors, but mainly depends on the filter material. The filter material of bag filter is a cloth or felt made of synthetic fiber, natural growth fiber or glass fiber. Sew the cloth or felt into a cylindrical or flat filter bag as needed. According to the properties of flue gas, the filter material suitable for application conditions is selected. Generally, polyester flannelette and polyester needle felt are often used when the flue gas sales are good and the temperature is lower than 120 ℃ and the filter material is required to have acid resistance and stable performance; Graphitized glass fiber cloth is mainly used to treat high-temperature flue gas (& lt; 250 ℃); In some special cases, carbon fiber filter material shall be selected

it is very important to control the speed of flue gas passing through the filter material (called filtration speed) in the operation of bag filter. Generally, the filtration speed is 0.5-2m / min. for particles greater than 0.1 µ m, the efficiency can reach more than 99%, and the resistance loss of the equipment is about 980-i470pa.
