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 micronic dust by special high-tension current device utilizes the electrostatic precipitation plate to adsorb utilizes water under high pressure to wash out, and also removes pernicious gas simultaneously.
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.
Because of burying the deficiency on ground, the less burning of mostly first-selected accessory substance is handled in recent years, and a lot of countries have dropped into a lot of funds in the construction of waste combustion factory.
But the dust or the pernicious gas that give off in the burning processing procedure of discarded object enter atmosphere, so need the antipollution purification facility of design.
Especially 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.
Facility precipitator for the air conservation of uses such as the dust that produces in the production process of removing the industry facility or the combustion plant and pernicious gas was to utilize the collecting plate positively charged in the past, electronegative by the waste gas between the collecting plate, pollutant such as absorption dust etc., but this method can not be removed the impurity in the combustion gas such as oxysulfide.
Therefore, developed the wet electrostatic dust arrester of water spray on the collecting plate being removed impurity such as oxysulfide when washing out adsorbed dust in recent years, but the main purpose of batch (-type) water spray is to remove the dust of collecting plate absorption, and is not high as for pollutant treatment effeciency in the gas.
Summary of the invention
The present invention studies in order to solve an above-mentioned difficult problem.For collecting plate continuity water spray is removed pernicious gas and dust simultaneously, electronegative discharge electrode and the fixed adsorption layer that is filled with active carbon and positively charged are set on the top of wet electrostatic dust arrester.Produce static in the time of not only can improving by discharge electrode like this and the absorption efficiency of electronegative pollutant, and the pollutant in the clean gases such as oxysulfide that are untreated during by the wet electrostatic dust arrester can be removed also.

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: in order to cool off and to purify the waste gas that enters along this machine 16 1 side air inlet pipe 1, the injector 3 of the water spray usefulness that below this machine 16, forms, the outlet 14 that the bottom has recovery to spray water, vertical discharge electrode 6 is being arranged on the upper strata of injector 3, in succession and keep vertical fixedly hammer 15 because of deadweight makes discharge electrode 6 in the lower end of discharge electrode 6, fixing hammer 15 is in and prevents between the lattice plate 17 to rock because of the flow velocity of waste gas, discharge electrode 6 is by accepting electric current by the insulator 7 on collecting plate 5 tops, discharge electrode 6 by insulator 7 ' accept electric current of electrostatic precipitator knoisphere 30 and electrostatic precipitator knoisphere 30 upper stratas ', and the adsorption layer 40 that is filled with a certain amount of granular active carbon 42.
The upper end of air inlet pipe 1 is provided with bend pipe 50, and the pernicious gas that passes through is at a high speed sprayed water, and the high concentrate dust that contains in the waste gas is tentatively removed.
The pernicious gas that reduces to some extent by dust content after the bend pipe 50 is during through discharge electrode 6, produces electrostatic interaction and electronegative.Therefore it can be attached on the collecting plate 5 that has positive electricity.
For on the collecting plate 5 of electrostatic precipitator knoisphere 30, forming moisture film and removing the dust layer that adheres to, injection valve 9 and washing valve 8 are installed.
In the another kind of structure of the present invention, under above-mentioned injector 3, 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.
In another structure of the present invention, above-mentioned 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.
The discharge electrode 6 of electrostatic precipitator knoisphere 30 and the discharge electrode 6 of adsorption layer 40 ' connection negative supply, collecting plate 5 is connected positive supply with adsorption layer 40, makes at discharge electrode 6,6 ' last 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.
Reach purification so pernicious gas that enters along air inlet pipe 1 and dust major part are adsorbed on after the cooling first in sprayer 3 on the collecting plate 5, the clean pollutants such as oxysulfide that wherein are untreated are adsorbed during by adsorption layer 40, discharge 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.
