Description
Technical field
The present invention relates to a kind of purifying vehicle exhaust method and device thereof, relate in particular to vehicle exhaust static and water absorbing composite purification method and device thereof.
Background technique
Along with expanding economy, automobile use amount is more and more, and motor vehicle exhaust emission has become important atmospheric pollution sources.In vehicle exhaust, contain NOx(oxynitrides), CO(carbon monoxide), HC(hydrocarbon) and micronic dust material (PM), people healthy formed to very large threat.Common treating vehicle exhaust method is to use auto-exhaust catalyst purification method, and the problem of this method is that the tail gas after catalysis still contains outside a large amount of harmful matter discharge cars, and environment is still had to pollution.Along with increasing of haze sky in recent years, at present in the urgent need to a kind of method and the device that can effectively eliminate automobile exhaust pollution source.
Summary of the invention
The technical problem to be solved in the present invention is method and the device thereof of harmful matter in a kind of purification absorbing automobile exhaust to be provided, thereby to weaken the pollution of automobile to atmosphere.
The present invention is achieved by the following technical programs: utilize Electrostatic Absorption method to adsorb the harmful matter in vehicle exhaust, particulate, utilize water and the aqueous solution to absorb the harmful matter in vehicle exhaust, particulate, device includes but not limited to the corona generation utmost point, collector, the aqueous solution, high-voltage power, ozone catalytic agent, ring magnet.
There is very wire netting in described corona.
Described collector is immersed in below aqueous solution surface.
Harmful matter in described aqueous solution absorbing automobile exhaust, carries out Chemical composition proportioning according to the composition of tail gas.
Described ring magnet enters the magnetic field of the aqueous solution for generation of guiding charged corpuscle.
Described ozone catalytic agent is coated on and absorbs collection surface.
Owing to adopting technique scheme, the present invention has such beneficial effect: utilize Electrostatic Absorption and the magnetic field deflecting effect to motion charged corpuscle, comprehensive absorption of hydrous water solution again, the harmful matter in absorbing automobile exhaust makes it not enter atmosphere environment neatly.

Embodiment
Metal in the corona generation being extremely made up of wire netting can be iron, copper or other metal, and its external coating has corrosion-resistant, high temperature resistant conductive material; Metal part in absorbing extremely can be iron, copper or other metallic material.Metal part outer surface in absorbing is extremely wrapped in the such as polyethylene of insulating material of one deck high resistivity etc., on insulating material, apply the coating of one deck ozone catalytic agent, ozone catalytic agent can be selected nickel oxide, the manganese oxide etc. that AL2O3 (aluminium sesquioxide) is carrier again.Collector can be netted.What in absorbing automobile exhaust, pollutant was used can be water or the aqueous solution, wherein the aqueous solution can carry out corresponding chemical proportioning according to the composition feature of pollutant, for example, for sour gas, the aqueous solution can be that alkaline aqueous solution is as lime water, sodium hydrate aqueous solution etc.
This device can be installed on vehicle-exhaust exhaust pipe silencing apparatus rear.
Below in conjunction with embodiment and accompanying drawing, the invention will be further described.
With reference to Fig. 1, it is the embodiment's of vehicle exhaust static and water absorbing composite purification method and device thereof schematic diagram.Device mainly comprises the corona generation utmost point 1, collector 2, ring magnet 3, aqueous solution liquid level 4, tail gas outlet 5, tail gas import 6, high-voltage power 7, radiating fin 8.
When device work, vehicle exhaust enters from tail gas import 6, contaminant particle in tail gas is brought static near corona occurs extremely, and particulate is absorbed enter the aqueous solution rapidly under the double action of magnetic core logical circuit deflection and the corona generation utmost point-collector formation electric field in.For reducing tail gas self-temperature, can be near tail gas import 6 finned 8 in advance to the tail gas processing of lowering the temperature.
Fig. 2 is embodiment's ring magnet schematic diagram, and figure comprises a polarity 1 and another polarity 2 of ring magnet.According to the charged character of particulate, installation direction and then the corrective action magnetic direction in charged moving particles that can adjust ring magnet according to long-range navigation Ci Dinglv, make charged moving particles moving direction all the time to the deflection of liquid level direction.
In collector, apply ozone catalytic agent coating, can increase the concentration of ozone in the aqueous solution, make the aqueous solution become hyperoxia voltinism solution.And for example SO2 (sulfur dioxide), the CO(carbon monoxide that in vehicle exhaust, contain), NOx(oxynitrides) be all much lower valency material, convert thereof into high valence state material and react with water by the aqueous solution of hyperoxia voltinism.For example sulfur dioxide generates sulfur trioxide through peroxidating, and sulfur trioxide generation sulfuric acid soluble in water.
For keeping the absorption efficiency of the aqueous solution, the aqueous solution in device can regularly replace or use water pump to carry out inflow and outflow of water.
Although be example object, some mode of executions of the present invention are disclosed, but those of ordinary skill in the art will recognize, in the situation that not departing from by the disclosed scope and spirit of the present invention of appending claims, various improvement, increase and replacement are possible.
