In view of the above-mentioned technological deficiency of prior art, establish in the urgent need to developing a kind of novel dedustingStandby.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming existing in prior art, provides a kind of wetFormula electric cleaner, this wet electrical dust precipitator can avoid having trapped the flying upward again of dust, efficiency of dust collectionHeight, reliable, water consumption is little and the water that consumes is recyclable,, can not meanwhileCause secondary pollution.
To achieve these goals, the utility model provides following technical scheme: a kind of wet type electricityDeduster, it comprises housing, the side lower part of described housing is provided with air inlet, bottom is provided withSewage draining exit, top are provided with gas outlet, it is characterized in that, the top in described air inlet and described inBelow in gas outlet is all provided with spray system, is also provided with described in being positioned to enter in described housingThe deflector of gas port top, establishes between described deflector and the spray system of below, described gas outletBe equipped with two electric discharge cathode fixing devices setting up and down, two described electric discharge cathode fixing devicesOn be fixed with the electric discharge negative electrode of multiple vertical settings, between described electric discharge negative electrode, be provided with anode and receiveDirt plate, is provided with on the cathode fixing device that discharges described in one of them to described electric discharge negative electrode power supplyHigh pressure unit.
Further, wherein, the below of described housing is also provided with the support of supporting described housingPost.
Further, wherein, the two ends of described electric discharge cathode fixing device are provided with and are positioned at instituteState the seal of hull outside, described high pressure unit is arranged on described seal.
Compared with existing cleaner, wet electrical dust precipitator of the present utility model has as follows and hasBenefit technique effect:
1, adaptable to dust, can reach very high efficiency of dust collection, meanwhile, also suitableFor the treatment of the flue gas of high temperature, high humidity.
2, there is no reentrainment of dust.
3, there is no the easily worn parts such as hammering equipment, reliability is high.
4, can effectively remove submicron particles, SO3The micro-drop of aerosol and gypsum, to controllingPM2.5, blue smoke and gypsum rain are respond well.
5, due to higher in electric cleaner internal electric field air velocity, the inclination angle of ash bucket reduces,The characteristics of compact layout of equipment, reduces total water yield of carrying in flue gas, reduces the probability that gypsum rain formsThe problem existing.
Brief description of the drawings
Fig. 1 is the composition schematic diagram of wet electrical dust precipitator of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated the content of embodimentNot as the restriction to protection domain of the present utility model.
Fig. 1 shows the composition schematic diagram of wet electrical dust precipitator of the present utility model. As Fig. 1 instituteShow, wet electrical dust precipitator of the present utility model comprises housing 2. In the utility model, preferablyGround, described housing 2 adopts common straightcarbon steel, and inner surface adds coating with anticorrosion. And, peaceWhen dress, to control breakage, particularly pad, the member junction etc. of inner surface. Described housing2 outside does not need insulation, because flue-gas temperature is lower than saturation temperature, thereby its flue gas is also severalNot cooling.
In addition, preferably, the below of described housing 2 is also provided with the support of supporting described housing 2Post 1. More preferentially, be provided with multiple support columns 1.
The side lower part of described housing 2 is provided with air inlet 3, bottom is provided with sewage draining exit 4, topBe provided with gas outlet 5. Preferably, the bottom of described housing 2 is provided with two sewage draining exits 4.
Below in top and described gas outlet 5 in described air inlet 3 is all provided with spray systemSystem 6. By described spray system 6, can injection water.
In described housing 2, be also provided with the deflector 7 that is positioned at described air inlet 3 tops. Described leadingBetween stream plate 7 and the spray system 6 of 5 belows, described gas outlet, be provided with two setting up and down puttingElectricity cathode fixing device 8. On two described electric discharge cathode fixing devices 8, be fixed with and multiplely vertically establishThe electric discharge negative electrode 9 of putting. Between described electric discharge negative electrode 9, be provided with anode dust collection plate 10. And, itsIn be provided with the height of powering to described electric discharge negative electrode 9 on a described electric discharge cathode fixing device 8Press group 11.
In addition, in the utility model, preferably, two of described electric discharge cathode fixing device 8End is provided with the seal 12 that is positioned at described housing 2 outsides. Described high pressure unit 11 is arranged onOn described seal 12.
Wet electrical dust precipitator of the present utility model is to overcome Water spray dust remover and electrostatic precipitatorOn the basis of drawback, grow up, its operation principle is the same with common deduster, mainRelate to that suspended particles are charged, charged particle moves and traps, and will trap thing in electric fieldRemove these three basic processes from dust arrester surface. This process is roughly: will by air inlet 3Dust-laden coal gas is transported in housing 2, and water is vaporific and sprays under the effect of spray system 6.Wherein, air inlet 3 places of deduster, the dust in dust-laden coal gas can with the water smoke of spray system 6Collide, and drop in ash bucket with the form of particle. In electric field region, charged water droplet due toIt electrically can be caught and drop on anode dust collection plate 10 by anode dust collection plate 10 under the effect of electric field forceUpper, and dust in coal gas also can be brought electrically after wetting by charged water droplet, therefore it also canDrop on anode dust collection plate 10, after anode dust collection plate 10 captures abundant water droplet, canOn anode dust collection plate 10, form moisture film, therefore captive dust is first by the mobile inflow of moisture filmIn ash bucket, and then enter in sedimentation basin by ash bucket.
Wet electrical dust precipitator of the present utility model by electric field by charged the particle in flue gas, soRear heavy collection is to pole plate, under the dust of heavy collection on pole plate can be rinsed by water. WetFormula deashing can be avoided having trapped flying upward again of dust, reaches very high efficiency of dust collection. Without rappingDevice, moves also more reliable. Dust collecting electrode adopts anti-corrosion electric conducting material to make, wet-espDevice does not need long-term water spray or overflow water, only regularly rinses according to system operation situation, onlyThe water that consumes minute quantity, this part water is recyclable, and dust collecting system is substantially without secondary dirtDye.
Above-described embodiment of the present utility model is only by clearly illustrating that the utility model is doneFor example, and be not the restriction to embodiment of the present utility model. For affiliated fieldThose of ordinary skill, can also make that other is multi-form on the basis of the above descriptionChange or variation. Here cannot give exhaustive to all embodiments. Everyly belong to this practicalityThe apparent variation that novel technical scheme is extended out or variation are still new in this practicalityThe row of the protection domain of type.
