Description
Technical field
The present invention relates to a kind of water fog charge device of realizing purifying vehicle exhaust integrated with plasma, and the structural design of this purification plant.
Background technique
Along with the sharply increase of automobile quantity, automobile exhaust pollution problem is extremely urgent.Vehicle exhaust mainly comprises carbon monoxide, hydrocarbon, nitrogen oxide and PM(particulate, soot) etc. harmful gas.Granular material discharged pollution in tail gas is the one of the main reasons affecting air quality.According to research to urban area of Beijing pollution of atmosphere in 2010, coal-fired and automobile pollution may be cause air-polluting main cause, and tail gas pollution of motor-driven vehicle endangers and exceeds fire coal, up to 22.2%.The contribution amount of current motor vehicle exhaust emission to PM2.5 remains dispute.But certainly, exhaust emissions is the key factor causing pollution of atmosphere.The deleterious particle of exhaust emissions not only comprises PM2.5, also includes PM10.
Chinese Government pays much attention to the city environmental pollution that improvement motor vehicle exhaust emission causes.By 2015, each place started progressively to implement Light-Duty Gasoline Vehicle state V emission standard.Along with the increasingly stringent of Abgasgesetz, purifying automobile tail gas discharge will be the study hotspot of a period of time from now on.Catalytic purification is a research direction of purifying vehicle exhaust technology, but the thermal stability problems etc. of blowdown when Problems existing mainly comprises cold-starting automobile and idling, catalyzer.From the eighties in 20th century, impulse electric corona plasma purification technics is developed fast.Research report shows, and plasma for purification technology can remove sulfur dioxide, nitrogen oxide and particulate pollutant.But the road promoting catalytic purification or plasma for purification technology at automotive field is not sailed right before the wind, and still there are some problems has to be solved.One is rational structural design.Due to the limited space at exhaust emissions position, the size of purification plant is little, avoids the larger change to original vehicle structure simultaneously; Purification plant can not impact the resistance of exhaust emissions in addition, otherwise affects the output power of motor; Two is durable high-field electrode or electrode method for cleaning easily.High-field electrode surface dirt there will be back corona phenomenon time more, and damaging dust removal apparatus even affects automotive safety.The method of current clearing electrode is vibratory drilling method, but in vehicle traveling process, electrode often can not get timely cleaning; Three is cost factors.Comprehensive, at present also not to the efficient apparatus of all kinds of purifying vehicle exhaust process.
Chinese Patent Application No. is 201110172175.7, publication date: on November 02nd, 2011, title: one realizes light-catalysed automobile exhaust gas purifying installation in vitro based on waiting.The method process vehicle exhaust that this invention utilizes plasma to be combined with Titanium Dioxide effect, titanium dioxide both produced plasma as a kind of insulating medium, and the aura again by plasma generation plays its light-catalysed effect.This invention can remove the toxic gases such as the nitrous oxide in tail gas, but does not provide the removal efficiency of PM particulate matter.
Summary of the invention
The object of the present invention is to provide a kind of simple and reasonable, simultaneously can the device of high-efficient purification vehicle exhaust, purification target comprises and reduces toxic gas in vehicle exhaust and PM particulate matter.
This device comprises water spray projector, plasma generator, purification controller and inclination injection pipe.
This device is installed do not need to carry out special transformation to former automobile exhaust pipeline, only needs to open a mouth in the upper rear end of outlet pipe.This mouth communicates with bottom inclination injection pipe, and such charged water spray can fully contact with tail gas from top to bottom.Getting exhaust emissions direction is forward, then the angle of inclination injection pipe and outlet pipe is 90 ° ~ 135 °.
The electrode of plasma generator is positioned at the middle part of inclination injection pipe, is close to tube wall.Electrode is clavate, passes to High Level AC Voltage.The conducting of High Level AC Voltage and cut-off can be controlled completely by purification controller.
The front end nozzle of water spray projector is placed in the upper end of inclination injection pipe.The centre of water spray projector is solenoid valve, and the closedown of solenoid valve and unlatching can be controlled completely by purification controller.The rear end of water spray projector is fixed on vehicle frame, is connected with water pump.
When vehicle exhaust flows to outlet pipe rear end, purification controller opens the solenoid valve of water spray projector respectively, and the high-voltage ac power of plasma generator.Water smoke, before injection enters exhaust duct, mixes with the electronics be ionized, Ion Phase, forms charged water spray, finally enters exhaust duct and be combined with vehicle exhaust, reaches the object reducing toxic gas and PM particulate matter in tail gas.
Compared with prior art, during apparatus of the present invention work, automobile exhaust resistance is not affected, thus harmful effect is not had to the Power output of motor.Better purifying space of the present invention is positioned at outlet pipe, avoids the back corona phenomenon of high-field electrode and the inconvenience of clearing electrode.
