Description
Technical field
The present invention relates to a kind of dust arrester of purifying harmful gas, be mainly used in the pernicious gas that purifies discharges such as factory.Specifically, the area that is arranged on the collecting plate in the equal volume by increase improves dust catching efficiency.
Background technology
The waste gas in general thermal power plant, the combustion gas of heating boiler is provided, the pernicious gas that produces in the steel-making iron-smelter heat treatment process, the pernicious gas that produces in the sulphuric acid recovery process of chemical plant, the pernicious gas that produces in the waste combustion equipment, the waste gas that produces in smeltery's heavy metal reclaimer and the optical cable manufacture process are being carried high concentration dust and harmful heavy metal etc. secretly and are being discharged and contaminated environment in the lump with the form of cigarette.Therefore, to utilize the waste sorting that can utilize again again when discarded object that produces in the process for producing activity or municipal refuse, bury processing for the discarded object that can rot in the discarded object that can not utilize again, burn to handle or be cured and be sunken to the seabed for having flammable material in the discarded object that can not rot.So in burning is handled, also produce a lot of dusts and pernicious gas.
Pollutants such as dust that the wet electrostatic dust arrester can adsorb and remove in such waste gas to be contained and pernicious gas are established the area of collecting plate in its control of dust ability and processing capacity depend on.The content of pollutants such as the big more or dust of the air quantity of waste gas is high more, and then the area requirements for collecting plate is high more.In order to satisfy such requirement, need to increase the scale of wet electrostatic dust arrester, so the corresponding apparatus expense must increase, and can occupy bigger space.
In addition, sulphur composition that contains in the waste gas and airborne combination with oxygen are discharged with the form of oxysulfide.Thereby cause steel construction facility corrosion such as production equipment and bridge, durability reduces, and expense increases.Particularly this material is the main cause that forms smog, and its toxicity can stimulate respiratory apparatus even cause PUD D.
Summary of the invention
The present invention proposes in order to solve an above-mentioned difficult problem.That is, press appointed interval in this machine of dust arrester volume inside and form the electrostatic precipitator knoisphere,, purify the charged waste gas that passes through at the division pars intramuralis of cutting apart to form cancellate division wall.
Important use of the present invention is a dust arrester.

The specific embodiment
Be with reference to describing representative structural principle in detail below with the accompanying drawing.Illustrate when respectively scheming that the same structural element that occurs is represented with identical symbol as far as possible in different figure.
Structure of the present invention is as follows as shown in accompanying drawing 1: the injector 3 that purifies the pernicious gas that contains pollutants such as dust for the first time, the lower end that is provided with between the collecting plate 5 is connected and fixed the discharge electrode 6 of hammer 15, the fixing hammer 15 lattice plates 17 that are fixed on the certain position, the porous plate 11 that lattice plate 17 lower ends are provided with, utilize bath to remove the washing valve 8 that collecting plate 5 adheres to dust, form in collecting plate 5 and space moisture film injection valve 9 and this machine of precipitator 16 of constituting such as vortex board 20, the air inlet pipe 1 that is formed by bend pipe 50 is arranged on the space of this machine one side, top is by the bending wet electrostatic dust arrester of forming such as injector 3 ' wait of the water of the header tank 21 of the ejection water that can circulate, above-mentioned collecting plate 5 is rearranged in dust collector body by a plurality of bodys 30 of both ends open up and down, waste gas is passed through by body inside, remove the oxious component that contains in the waste gas.
The Cross section Design of particularly above-mentioned body 30 becomes quadrangle or hexagon, makes the adjacent body 30 can public outer wall.Save material like this, and unnecessary space is minimized, prevented the increase of dust arrester scale.
For above-mentioned discharge electrode 6 is not rocked with flowing of waste gas, the lower end has connected the fixedly hammer 15 that constant weight is arranged, and makes its tight arrangement with lattice plate 17.
In the another kind of structure of the present invention,, can in this machine 16, be uniformly dispersed, increase the porous plate 11 more than at least 1 in order to make the waste gas that enters under the injector 3.
In another structure of the present invention, injector 3 lower ends are designed to plane of bending, fill the mass filler 22 that has enlarged surface area, make the packing layer 20 of its formation more than 1 layer, increase the water of ejection and the contact area of waste gas like this, improved the absorption treatment effeciency of waste gas.
In the third structure of the present invention, the top of collecting plate 5 be provided with the adsorption layer 40 of filling a certain amount of active carbon 42 and the discharge electrode 6 by insulator 7 ' accept electric current ', make the pernicious gas that does not purify be adsorbed processing, further improved exhaust purification efficiency, waste gas is further purified.
The following describes job state of the present invention in the said structure.
The waste gas that enters dust arrester inside along air inlet pipe 1 runs into behind the water under high pressure of injector 3 ejections temperature and descends and purify first, again by porous plate 11 or packing layer 20, arrives collecting plate 5 afterwards.
The discharge electrode 6 that forms between the collecting plate 5 and the discharge electrode 6 ' connection negative supply of adsorption layer 40, collecting plate 5 is connected positive supply with adsorption layer 40, makes at discharge electrode 6,6 ' charged pernicious gas to be attracted to easily on collecting plate 5 or the adsorption layer 40.
This is to utilize the same sex to repel each other, the principle that there is a natural attraction between the sexes.
Pernicious gas that enters along air inlet pipe 1 and dust major part are adsorbed on collecting plate 5 after the cooling first and reach purification in sprayer 3, the clean pollutants such as oxysulfide that wherein are untreated are adsorbed during by adsorption layer 40, discharge than pure gas.
As mentioned above, the present invention has improved the treatment effeciency of dust in offal treatment process exhaust gas discharged, also can absorb the pollutant in the combustion gas such as handling oxysulfide simultaneously.
