Description
Technical field
The present invention relates to automobile exhaust gas purifying installation technical fields, and in particular to a kind of tail gas of anti-vehicle exhaust diffusion is net
Change system and its working method.
Background technique
It is directly discharged in air currently, the engine exhaust of nearly all fuel combustion vehicle is vented exhaust pipe by it,
These tail gas contain the pernicious gases such as a large amount of sulfide, nitrogen oxides, carbon, lead and pellet, these exhaust emissions
Object distributivity diffuses in air, is continuously increased the degree of pernicious gas in air, floating dust, haze, serious ground contamination
The living environment of the mankind threatens the health of the mankind.
Automobile manufacture industry mainly takes emission controls by improving combustion and external purification (exhaust aftertreatment) measure, machine to the purification of exhaust gas
It is inside electronic control system to be sprayed using closed loop fuel, that is, lean on lambda sensor feedback control, there are also exhaust gas to recycle (EGR
Valve) system inhibits the generation of nitrogen oxides.External purification is discharge can be made useless by three unique catalytic converter (exhaust aftertreatment)
Harmful components CO, HC, NO in gasxThere is certain decline.Due to factors, automobile will cause after travelling one section of mileage
Lambda sensor and ternary catalyzing unit poison deactivation, ternary catalyzing unit blocking and EGR valve are deposited the failures such as object obstruction clamping stagnation, from
And cause the problems such as engine emission controls by improving combustion is abnormal, tail gas is exceeded.It many times arises a problem that and is not also noticeable,
Motor Maintenance also and is changed without correlated parts, causes not to be purified with disease still traveling discharge.Even if ternary catalyzing unit
It does not fail, still has part pernicious gas and be discharged and spread in air, or even thick smoke is caused to have no to block.This is
Because being holding idle stability without exhaust gas recirculatioon, full load during general exhaust gas recycling system warming-up and when idling
With to make engine have enough dynamic property also without exhaust gas recirculatioon, inevitably still have so more when high speed
The discharge of NOx can not limit.
In order to inhibit NOxDischarge, someone has developed SCR system, i.e., automobile-used selective catalytic reduction exhaust aftertreatment
(SCR) system, a kind of technology reacted again with vehicle exhaust by the ammonia that urea reaction generates, but SCR is one
Complicated system, there is also following deficiencies other than structure is complicated: 1, SCR installation is complicated, at high cost, must dispatch from the factory in automobile
Preceding installation.2, production urea can also cause secondary pollution.3, SCR does not have effect must the pollutants such as CO, CH, particle in tail gas
Other equipment must be installed additional.4, SCR requires automobile intelligent high, is easy to cause automobile that can not light a fire.5, it is assembled with SCR post-processing system
Most of vehicles all cause the new fault point of vehicle after system, not high so as to cause present SCR popularity rate.Soot is used in diesel vehicle
Particle purification, also only uses millipore filter.Filter work a period of time will also remove the particle accumulated on filter core in time,
Otherwise it will increase exhaust resistance.Also fan is installed in exhaust ports to prevent from blocking in filter, also some with spraying again
Gasoline puts the substance burn-up that torch gets lodged in filter port again.But these methods, which exist, generates new harmful components release, Bu Nengjing
Change exhaust gas, cannot especially prevent Tail Gas from spreading in urban environment and pollute, and environment temperature is increased.
Summary of the invention
The purpose of the present invention is to provide the exhaust gas purification systems and its working method of a kind of anti-vehicle exhaust diffusion, this is

1) when automobile engine works, activation system, electrodynamic pump is started to work;
2) electrodynamic pump extracts aqueous out from water tank, is transported to injection spray pipe by pressure piping after pressurization;
3) injection spray pipe ejects water mist by distribution pipe thereon and nozzle, blocks vehicle exhaust, and with the powder in vehicle exhaust
Dirt, exhaust gas sufficiently collide cohesion, reaction;
4) water mist of vehicle exhaust is absorbed by the blocking of spraying baffle, is converged into collector tube, is then back to catch box.
7. a kind of working method of the exhaust gas purification system of anti-vehicle exhaust diffusion according to claim 6, feature exist
In the setting angle set on each nozzle of injection spray pipe rear end tilts set angle to spraying tube hub, to work as all nozzles simultaneously
When spraying water mist, contraction-like water mist wall is formed, vehicle exhaust is sufficiently blocked.
8. a kind of working method of the exhaust gas purification system of anti-vehicle exhaust diffusion according to claim 6, feature exist
In added with nitric acid tobacco inorganic agent in the water of the water tank.
