Abstract
The invention relates to an electrostatic and fabric composite filter which comprises a housing, and an electrostatic precipitation region and a fabric filter region which are arranged in the housing, wherein a flue gas distributor is arranged between the electrostatic precipitation region and the fabric filter region, and an adjustable baffle plate is arranged at the lower part of the flue gas distributor. A gas flow direction is changed by the flue gas distributor, and thus gas flow is prevented from directly impacting a filter bag; by adjusting the opening of the adjustable baffle plate, a flow ratio of flue gas entering the fabric filter region from the side surface and the bottom can be controlled, so that the gas is reasonably distributed; meanwhile, the electrostatic and fabric composite filter is simple in structure, easy to manufacture and convenient to use and maintain, and the maintenance cost and dust precipitation cost are greatly reduced.
Description
Technical field
The present invention relates to a kind of industrial smoke deduster, be specifically related to a kind of electric-bag complex dust collector.
Background technology
For the dust arrester of industrial smoke processing, be mainly electric cleaner and bag type filtering deduster at present.Sack cleaner efficiency of dust collection is high, stable, but operating cost compared with high, maintenance workload is large, and be not suitable for that temperature is high, the dust of viscosity and high humidity.Electric cleaner resistance is little, operating cost is low, it is strong to adapt to flue gas changing capability, but the scope of application is subject to the impact of Dust Characteristics and dials, and has degradation problem under long-play behind efficiency.In recent years, developed electric bag composite dedusting technology in order to overcome the defect of above-mentioned two kinds of traditional cleaners, this technology organically combines two kinds of dedusting technologies, compared with single cleaner, have efficiency of dust collection high, efficiency of dust collection is not subject to dust properties influence, can be satisfied with the service requirement under different working conditions, efficient stable, running resistance is low, and filter bag dust load amount is few, dust size is little filter bag is washed away little, life of bag filter is long, the little technical characterstic that waits of maintenance.
But there is the defect of gas flowfield irrational distribution in existing electric-bag complex dust collector, reduce bag-type dusting effect, affect the life-span of filter bag, thereby improved customer using cost.
Chinese patent 200910261104.7 discloses a kind of electric-bag complex dust collector, has significantly improved the chargeability of dust, has improved efficiency of dust collection, and has effectively avoided leak-off pocket directly adjacent with discharge electrode, thereby has extended the leak-off pocket life-span, has reduced dedusting cost.But this invention complex structure, manufactures and designs difficulty large, install complicatedly, use, maintenance cost is high.
Summary of the invention
The object of the invention is the defect in order to overcome existing electric-bag complex dust collector, a kind of gas flowfield reasonable layout, electric-bag complex dust collector that cost is low are provided.
In order to achieve the above object, the technical solution used in the present invention is:
A kind of electric-bag complex dust collector, comprises casing and is arranged on electric precipitation district and the bag-type dusting district in casing, described electric precipitation district and bag-type dusting interval are provided with smoke distributor, and described smoke distributor bottom is provided with fender plate.
Further, described smoke distributor is the grid being made up of arc, and the filter bag in the grid of described smoke distributor and bag-type dusting district is contour.
Again further, described fender plate is venetian blind type.
The invention has the beneficial effects as follows: smoke distributor has changed gas flow, avoid air-flow directly to impact filter bag, by regulating the aperture of fender plate, can control flue gas from the side and enter the flow proportional in bag-type dusting district from bottom, make distribution of gas more reasonable, simultaneously simple in structure, easy to manufacture, use, easy to maintenance, greatly reduces maintenance cost and dedusting cost.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
In Fig. 1, casing 1, electric cleaner district 2, sack cleaner district 3, smoke distributor 4, fender plate 5;
Fig. 2 is smoke distributor 4 schematic diagrames of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
A kind of electric-bag complex dust collector as shown in Figure 1 and Figure 2, comprise casing 1 and be arranged on electric precipitation district 2 and the bag-type dusting district 3 in casing, between electric precipitation district 2 and bag-type dusting district 3, be provided with smoke distributor 4, the grid of smoke distributor 4 for being formed by arc, the filter bag in the grid of smoke distributor and bag-type dusting district is contour, smoke distributor 4 bottoms are provided with fender plate 5, and fender plate is venetian blind type.
Dusty gas passes through cathodic discharge by air inlet by the laggard people's electric precipitation of airflow uniform distribution device district 2, anode gathers dust, collect most of dust in flue gas, dust-collecting efficiency is greater than more than 80%, having collected gas after most of dust also contains some not collect the fine dust ionization of getting off charged, containing fine dust ionizes charged fine dust and controls into people's bag-type dusting district 3 through smoke distributor 4 and fender plate 5 with flue gas, filter, ash-laden gas passes through filter bag, dust is delayed at the outside of filter bag, after purifying, gas enters people top air-purifying chamber by filter bag inner chamber and then imports air draft flue and give vent to anger.
Claims (3)
