A bag filter is a box in which a short electric field is installed at the front end and a filter bag field is installed at the back end. The dust is introduced from the left end and first passes through the electric field area. The dust particles are charged by the electric field area and 80%~90% of the dust is collected.
(Play to the advantages of electric dust removal, reduce bag load).
Part of the flue gas passing through the electric field enters the bag area and enters the inner cavity of the filter bag through the outer surface of the filter bag. The dust is blocked in the outer surface of the filter bag, and the pure gas is discharged from the inner cavity exhaust flue.
Material of filter bag:
Natural fiber, chemical synthetic fiber, glass fiber, metal fiber.
Form:
The gas goes from the outside of the filter bag to the inside, and the dust is on the outside of the filter bag
Gas from the filter bag to the outside, dust in the inner surface of the filter bag
Service temperature:
For the bag filter, its use temperature depends on two factors, the first is the filter material's maximum bearing temperature, the second is the gas temperature must be above the dew point temperature.
Due to the large selection of glass fiber filter material, its maximum temperature can reach 280℃. Cooling measures must be taken for the gas above this temperature, and heating measures must be taken for the gas below the dew point temperature.
