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.

The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model comprises the housing 5 of sealing, and what be positioned at housing 5 comprises electric field part and filter bag part.These two parts are alternately arranged.After flue gas enters deduster, baffle plate 1 barrier air of filter bag front enters the filter bag district and guides flue gas to flow to electric field, electric field segment anode 3 is arranged on the filter bag both sides, discharge electrode 2 is between anode, the electric field deashing adopts mechanical vibrator, electromagnetic rapping or sound wave ashing, filter bag ash removal adopts the pulse valve deashing device.The positive plate 3 of positive plate part is perforate pole plate or stripe board, and when described positive plate 3 was the perforate pole plate, percent opening was 30-60%, and when positive plate 3 was stripe board, the gap of stripe board was 50-150mm.
After flue gas entered the utility model, because baffle plate 1 blocks the filter bag of front end, so flue gas made air ionization earlier by the static electric field of prickle wire 2 is arranged under the effect of high voltage electric field.After dust is charged, under the effect of electric field force, by charged polarity difference, move separately to opposite electrode.Flowed to filter bag 4 by the flue gas of preliminary purification hole or gap by positive plate 3 under the effect of air-introduced machine, the dust of being collected by positive plate 3 is not intercepted at outside the filter bag, the flue gas that purifies upwards enters air-purifying chamber from the filter bag the inside, enters chimney again, finishes dust removal process.Positive plate 3 is by the mode deashing of rapping or sound wave, and filter bag 4 is by the mode deashing of pulse.
Charged dust agglomeration is on the surface of filter bag 4, and change has taken place the dust proterties, and a part of dust cohesion has become bigger particle, because the charged dust of the same sex repels each other, the dust on filter bag surface is arranged in order loose, and filtration resistance and deashing resistance significantly reduce.Simultaneously, when the filter bag pulse dust cleaning, next-door neighbour's electric field energy captures the dust that is scattered effectively, has reduced the possibility that dust is entrained to filter bag once more, has greatly improved the condition of work of filter bag.The utility model has realized that resistance also is no more than 1500Pa when air cloth ratio 〉=2m/min.Under the condition of handling identical tolerance, the quantity that filter bag, bag cage and pulse valve require still less can reduce initial cost and operating cost.And the utility model has higher capture effect to the PM2.5 fine dust, causes the outlet concentration of emission lower, even can reach and be not more than 30mg/Nm 3, meet the demand for development of atmosphere polluting controling technology from now on.
