Abstract
The utility model discloses a novel electrostatic bag dust collector which organically combines an electrostatic dust collector with a bag dust collector into a same air chamber. An electrostatic part (a discharging electrode and a dust-collecting electrode) and a filter bag part are alternately arranged. Flue gas firstly passes through an electric field, before reaching the filter bag, the majority of particles carried by the flue gas are adsorbed on a dust-collecting electrode plate, the primarily purified flue gas flows to the filter bag through a gap of the dust-collecting electrode plate, and the flue gas is further purified by the filtering effect. When the filter bag is used for cleaning dust, the electric field effectively prevents the dust from re-adhering to the filter bag, and the possibility of carrying the dust on the filter bag is greatly reduced. The electrostatic bag dust collector is efficient, compact, capable of capturing PM2.5 superfine particles and synergetically removing other pollutants, low in resistance and suitable for modification of the electrostatic dust collector, has great potential in the future development and greatly improves the filtering wind speed of the filter bag.
