Description

Vehicle exhaust spray absorber purifier

Specification

Technical field

A kind of prevention and control of air pollution device is the utility model is related to, especially a kind of vehicle exhaust spray absorber purifier

Background technology

Existing purifying vehicle exhaust, is often carried out with installing the method for ternary catalyzing unit on automobile, when automobile discharge When tail gas passes through ternary catalyzing unit, three kinds of gases of nitrogen dioxide, nitric oxide, carbon monoxide in vehicle exhaust, are urged in ternary Change and redox reaction occurs in device under the action of catalyst, nitrogen dioxide, conversion of nitric oxide gas are converted into nitrogen, carbon monoxide Discharged into carbon dioxide, it is such a ternary catalyzing unit purify vehicle exhaust by way of can only there is shortcoming, nitrogen dioxide A part is removed, also has substantial portion of nitrogen dioxide to remove, sulfur dioxide can not remove, PM2.5 particulate matters It cannot remove, here it is, although automobile is assembled with ternary catalyzing unit to purify vehicle exhaust, two in vehicle exhaust Sulfur oxide, PM2.5 particulate matters, a part of nitrogen dioxide cannot still remove, and cause vehicle exhaust to become a master of atmosphere pollution Reason is wanted, vehicle exhaust ratio shared in atmosphere pollution source reaches 30-40%.

Now, purifying vehicle exhaust method, some generally make absorbent using calcium hydroxide solution, sodium hydroxide solution Vehicle exhaust is purified, these make vehicle exhaust absorbent with calcium hydroxide solution or sodium hydroxide solution, to purify vehicle exhaust Method there is also shortcoming, first, such a method can only remove sulfur dioxide, it is impossible to remove nitrogen dioxide, second, after absorption Product calcium sulfate because being precipitation, easily separate, purify from the waste liquid after absorption, still, product calcium nitrate after absorption, Sodium nitrate is not precipitation, it is not easy to separates, purifies from the waste liquid after absorption, cause the waste liquid after absorbing not handle, third, Even if separation, the calcium sulfate purified out, because limited to the needs of calcium sulfate in society, if the method is promoted on the automobile in the whole nation Use, must at least produce millions of tons of calcium sulfate, and hundreds of thousands ton is no more than to the demand of calcium sulfate in society, so Will result in calcium sulfate accumulation cannot efficiently use and pollute environment, just because of above-mentioned reason, illustrate calcium hydroxide solution Or sodium hydroxide solution is not suitable for making vehicle exhaust absorbent, why someone is after not accounting for absorption in this way Liquid waste processing it is difficult, good method should be the succession that can be removed in vehicle exhaust and make the waste liquid after absorption Easily carry out harmless treatment and beneficial to utilization.

The utility model, vehicle exhaust spray absorber purifier, absorbent used produce absorption waste liquid, easily into Row harmless treatment, the material purified from waste liquid can be used as field crops and the fertilizer of other crops, can largely use In proportion of crop planting, nearly 100% can be reached to the waste liquid after absorption beneficial to utilizing, nearly 0 discharge to sulfur dioxide in vehicle exhaust, Three kinds of PM2.5 particulate matters, nitrogen dioxide successions can reach near-zero release.

If this vehicle exhaust absorption cleaning method is promoted the use of in the whole nation, even if absorbing waste liquid purification reaches millions of Ton, or even up to ten million tons, are in great demand because it can do Crop fertilizer, utilize so also can all sell, reach 100% Beneficial to utilizing, the raffinate absorbed after waste liquid purification is pure water, is recycled available for absorbent is prepared, after so absorbing Waste liquid has reached zero-emission, and 100% beneficial to utilization.

Utility model content

In order to overcome in the prior art, sulfur dioxide, PM2.5 particulate matters cannot remove in vehicle exhaust, greatly The shortcomings of nitrogen dioxide cannot remove, the present invention provide a kind of device that vehicle exhaust is purified using spray absorber mode, will When vehicle exhaust is by this device, sulfur dioxide, PM2.5 particulate matters, these pollutant components of nitrogen dioxide and mist in vehicle exhaust The absorbent of shape is contacted and is predominantly absorbed, in this way, the vehicle exhaust of discharge is exactly clean.After testing, by vehicle exhaust After absorbing and purifying device, the content of sulfur dioxide, PM2.5 particulate matters, nitrogen dioxide realizes vapour all close to 0 in vehicle exhaust Nearly 0 discharge of three kinds of sulfur dioxide, PM2.5, nitrogen dioxide components in tail gas.

Embodiment

The utility model solves the technical solution that its technical problem uses：A kind of vehicle exhaust spray absorber purification dress Put, including Spray absorber, absorbent case, Spray absorber are diameter 10cm, long 40cm, horizontal positioned metal tube, sprays The vehicle exhaust air inlet of diameter 5cm is equipped with the left of absorber, right side is equipped with the vehicle exhaust gas outlet of diameter 5cm, shower head pipe From top, intermediate vertical extend into Spray absorber centre position, and nozzle is towards air inlet.

Absorbent case is long 40cm, width 40cm, the metal box of high 20cm, and Spray absorber is located at 5cm above absorbent case Place, both are connected by the metal tube of diameter 3cm, long 5cm, and absorbent bottom portion is equipped with the valve of discharge absorbent, top Addition mouth equipped with absorbent, is equipped with pump intake in absorbent bottom portion, water pump by hose respectively with water inlet, nozzle It is connected, in this way, water pump together form one by hose and nozzle, Spray absorber and absorbent case connecting tube, water inlet Absorbent liquid circulation loop.

Above-mentioned vehicle exhaust spray purification device, metallic conduit and former vapour of the Spray absorber air inlet by diameter 5cm Vehicle exhaust mouth is connected, and the vehicle exhaust after absorption cleaning is arranged by the metallic conduit of diameter 5cm in Spray absorber gas outlet It is put into air, on the left of air inlet, successively equipped with filter screen, small wind turbine, on the right side of gas outlet, successively equipped with filter screen, small wind turbine, Spray absorber is connected by metallic conduit with former automobile exhaust port, under the action of small wind turbine, forms a vehicle exhaust Introduce, the passage that spray absorber is purified, discharged, vehicle exhaust spray absorber purifier position is placed in automobile trunk.
