Description
Technical field
The present invention relates to motor vehicle tail-gas purifying field, relate in particular to a kind of purification plant of motor-driven vehicle aerated particle.
Background technique
Current Motor Vehicle is many convenience that the mankind bring as the means of transportation that people are main, but along with the sharply increase of Motor Vehicle particularly automobile pollution, development for city brings certain atmospheric pollution, toxic emission in motor-vehicle tail-gas accounts for more than 40%, become main pollution source, wherein containing a large amount of CO, NO
x, harmful gas and the flue dust such as HC, be detrimental to health, a lot of scheme is put into effect in order to administer urban air pollution various places, comprise the measures such as vehicle is restricted driving, limit is purchased, water sprinkling path and water spray, indirectly improve the air quality in city, but these treatment measures limit the normal life of people, also bring some inconvenience to people's life.
Can certainly by the quality improving catalytic reactor, EGR Technology, engine technology, fuel qualities ensure air, particularly three-way catalytic converter effect is wherein better.Specifically the waste gas in outlet pipe is directed into this device, utilizes the platinum, palladium, rhodium etc. of the hot properties of waste gas itself and device inside as catalyzer, make CO, NO
x, there is chemical reaction in HC, is converted into the CO directly do not endangered personage
2, N
2, H
2o etc., but three-way catalytic converter well can not remove the particle in tail gas, and these particles can have a strong impact on the air quality in city equally, are therefore badly in need of further separating particles on the basis of three-way catalytic converter, to improve air quality further.
Summary of the invention
The object of the present invention is to provide a kind of purification plant of motor-driven vehicle aerated particle, under the prerequisite raised the cost not significantly, can effectively remove the particle in tail gas.
The purification plant of the motor-driven vehicle aerated particle in this programme, include the silencing apparatus be arranged on tailpipe, the cross section ovalisation of the housing of described silencing apparatus, the inner walls of silencing apparatus is also provided with demarcation strip, described demarcation strip comprises the first demarcation strip being arranged on muffler inlet, be arranged on second in the middle part of silencing apparatus and the 3rd demarcation strip and be arranged on the 4th demarcation strip of muffler outlet, the first suction port is provided with below described first demarcation strip, the first supporting network of fixing ternary catalyzing unit is provided with between described first demarcation strip and the second demarcation strip, described second demarcation strip top is provided with first row gas port, the second suction port is provided with bottom described 3rd demarcation strip, second exhaust port is provided with above described 4th demarcation strip, one deck tail gas distribution grid is provided with between 3rd demarcation strip and the 4th demarcation strip, and flood the cleaning water layer of tail gas distribution grid.
The purification plant of the motor-driven vehicle aerated particle of this programme is adopted to have following advantage: because ternary catalyzing unit is arranged between the first and second demarcation strips, cleaning water layer is arranged between the third and fourth demarcation strip, tail gas enters the rear ternary catalyzing unit that first passes and carries out chemical reaction bottom the first demarcation strip, harmful gas is changed into common gases, generating portion water simultaneously, tail gas is through second and the 3rd interlayer of demarcation strip, then enter from the second suction port, then through tail gas distribution grid bubbling in cleaning water layer, under particle in tail gas is cleaned washing, clean tail gas enters into air through second exhaust port, thus realize particulate burning purifying, owing to only consuming common water, therefore cost improves little.
Preferably, described second demarcation strip is equal with the aperture of the second suction port with the spacing of the 3rd demarcation strip, arranging like this can make the air inflow of the second suction port relatively suitable, thus avoids a large amount of rinse water oppositely to flow between the second demarcation strip and the 3rd demarcation strip.
Preferably, pitch-row on described tail gas distribution grid from the second suction port more away from closeer, arranging like this can make tail gas be more evenly distributed from tail gas distribution grid after entering from the second suction port, position near the second suction port is comparatively sparse, but now tail gas pressure is large, and bubbling is fast, position away from the second suction port is comparatively tight, but now pressure is relatively little, bubbling can be comparatively slow, and overall meeting is more even.
Preferably, the water intake being connected to water tank is provided with above described housing, this water intake is arranged between the 3rd demarcation strip and the 4th demarcation strip, arranging like this can make rinse water obtain certain compensation, avoid because high temperature causes rinse water to run out, can not at continuation cleaning of off-gas particle.
Accompanying drawing explanation
