Dust remover is mainly composed of enclosure, the enclosure, ash hopper, into the wind tube, filter bag and flow injection device, discharge device, etc. Dust gas from dust in the wind pipe flow into each room ash hopper, and the ash hopper guiding device, under the guide of large particles of dust is separated, directly into the hopper, and a fine dust evenly into the middle box body and adsorption on the outer surface of the filter pocket, clean gas through the filter bag into the box body, and the offline valve and exhaust duct into the atmosphere. As the working condition of filter, filter bag dust pile up, when a device to limit the resistance value of resistance (typically set to 1500 pa), controlled by the ash removal device according to the differential pressure value or soot cleaning time automatically closed one room offline after valve, open the electric pulse valve, according to the setup program to stop the wind blowing, the use of compressed air blowing moment so that the pressure in the filter bag together, to shake off the dust on the filter bag (although can more thoroughly clear stick fine dust ash) into the hopper, discharge from row of institutions.
1) The dust removing efficiency is over 99.9% and emission concentration is less than 30mg/Nm3.
2) High density dust air below 1000mg/Nm3 is available.
3) Off-line pulse cleaning method which can clean ash thoroughly and the running resistance is small.
4) It has stable and reliable performance, high degree of automation and low investment.
