Abstract
The present invention relates to a kind of automobile exhaust gas purifying installation.Comprise the suction tude of outlet pipe and the inlet end being connected to engine exhaust end, be connected to the baffler of outlet pipe tail end, be provided with exhaust gas particle segregating unit between described outlet pipe and baffler, described exhaust gas particle segregating unit is connected to suction tude by exhaust gas particle conveyance conduit pipeline through air filter.Tail gas after engine combustion is by outlet pipe inflow exhaust gas particle sorting apparatus, the diameter of sufficient combustion that do not have in tail gas is that 0.1 ~ 0.5 μm of burnable granule is separated by exhaust gas particle segregating unit, and the tail gas after separation is by being discharged in air after baffler noise reduction.The burnable granule be separated is input in suction tude by exhaust gas particle conveyance conduit, with diesel engine again burning by the burnable granule of separation being entered firing chamber after air filter filters during suction tude inhale fresh air in suction stroke, effectively to solve the insufficient exhaust emission caused of burning.
Description
Technical field
The present invention relates to a kind of purification plant, be specifically related to a kind of automobile exhaust gas purifying installation.
Background technique
When diesel vehicle is from process at one's side time, often can see afterbody over-emitting black exhaust, this is exactly the particulate matter (PM: ParticulateMatter) of motor partial combustion discharge in fact.The particle that motor is discharged can be divided into white cigarette, blue smoke and black smoke three kinds.White cigarette is from the fuel oil of condense steam and unburned.Blue smoke is from unburnt fuel oil and machine oil; These two kinds of cigarettes are all do not reach operating temperature because of motor and load is too low caused, after motor reaches operating temperature and load increases, and will Lock-out.Black smoke, then from fuel oil or machine oil, because the heavy sulphur content in the rough running of diesel engine, fuel can not perfect combustion, enters air with effluent, its diameter is at about 0.1 ~ 0.5 μm, not only cause the waste of the energy, and these small-particles are easy to be inhaled in respiratory tract, cause serious disease.
The research of diesel engines at present exhaust aftertreatment launches around elimination NOx and PM, but the formation of NOx and PM and content exist mutual restricting relation.Make great efforts to reduce one, another pollutant must be caused to increase.While reduction NOx, the particulate trap adopting cost high catches, then by regeneration techniques combustion particle thing.The waste gas treatment cost not only increased in this way, and cause the waste of the energy.
Summary of the invention
The present invention, in order to overcome the deficiency of above technology, provides the diesel engine exhaust purification plant of a kind of waste gas circulation burning.
The present invention overcomes the technological scheme that its technical problem adopts:
This diesel engine exhaust purification plant, comprise the suction tude of outlet pipe and the inlet end being connected to engine exhaust end, be connected to the baffler of outlet pipe tail end, be provided with exhaust gas particle segregating unit between described outlet pipe and baffler, described exhaust gas particle segregating unit is connected to suction tude by exhaust gas particle conveyance conduit pipeline through air filter.
Above-mentioned exhaust gas particle segregating unit is the exhaust-steam separator of pipeline twist, the inlet end of described exhaust-steam separator is connected to its outlet end of suction tude and is connected to exhaust gas particle conveyance conduit, the outer diameter tube of described waste gas exhaust pipe is less than the diameter of bore of exhaust-steam separator outlet end, and described exhausting waste gas tubular portion sealing is inserted in exhaust-steam separator outlet end also fixing.
Controlled in order to realize exhaust gas particle amount, the control damper also comprising ECU and be arranged on exhaust gas particle conveyance conduit 9, described control damper is connected to ECU
The invention has the beneficial effects as follows: the tail gas after engine combustion is by outlet pipe inflow exhaust gas particle sorting apparatus, the diameter of sufficient combustion that do not have in tail gas is that 0.1 ~ 0.5 μm of burnable granule is separated by exhaust gas particle segregating unit, and the tail gas after separation is by being discharged in air after baffler noise reduction.The burnable granule be separated is input in suction tude by exhaust gas particle conveyance conduit, with diesel engine again burning by the burnable granule of separation being entered firing chamber after air filter filters during suction tude inhale fresh air in suction stroke, effectively to solve the insufficient exhaust emission caused of burning.

Fig. 1 is structural representation of the present invention.
In figure, 1. air filter 2. outlet pipe 3. suction tude 4. exhaust-steam separator 5. control damper 6. baffler 7.ECU 8. waste gas exhaust pipe 9. exhaust gas particle conveyance conduit.
Embodiment
Below in conjunction with accompanying drawing 1, the present invention will be further described.
This diesel engine exhaust purification plant, comprise the suction tude 3 of the outlet pipe 2 and inlet end being connected to engine exhaust end, be connected to the baffler 6 of outlet pipe 3 tail end, be provided with exhaust gas particle segregating unit between described outlet pipe 2 and baffler 6, described exhaust gas particle segregating unit is connected to suction tude 3 by exhaust gas particle conveyance conduit 9 pipeline through air filter 1.Tail gas after engine combustion is by outlet pipe 3 inflow exhaust gas particle sorting apparatus, the diameter of sufficient combustion that do not have in tail gas is that 0.1 ~ 0.5 μm of burnable granule is separated by exhaust gas particle segregating unit, and the tail gas after separation is by being discharged in air after baffler 6 noise reduction.The burnable granule be separated is input in suction tude 3 by exhaust gas particle conveyance conduit 9, with diesel engine again burning by the burnable granule of separation being entered firing chamber after air filter filters during suction tude 3 inhale fresh air in suction stroke, effectively to solve the insufficient exhaust emission caused of burning.
Above-mentioned exhaust gas particle segregating unit is the exhaust-steam separator 4 of pipeline twist, the inlet end of described exhaust-steam separator 4 is connected to its outlet end of suction tude 3 and is connected to exhaust gas particle conveyance conduit 9, the outer diameter tube of described waste gas exhaust pipe 8 is less than the diameter of bore of exhaust-steam separator 4 outlet end, and described waste gas exhaust pipe 8 part sealing is inserted in exhaust-steam separator 4 outlet end also fixing.When the tail gas after burning enters exhaust-steam separator 4 from outlet pipe 8 time, due to exhaust-steam separator 4 twist, therefore waste gas forms eddy current in exhaust-steam separator 4, produce huge centrifugal force, particulate matter will be thrown to inner pipe wall, outer diameter tube due to waste gas exhaust pipe 8 is less than the diameter of bore of exhaust-steam separator 4 outlet end, therefore the burnable granule after being separated is from the space inflow exhaust gas particle transport pipeline 9 between waste gas exhaust pipe 8 and exhaust-steam separator 4, and remaining waste gas directly flows into baffler 6 by waste gas exhaust pipe 8.
Also comprise ECU 7 and be arranged at the control damper 5 on exhaust gas particle conveyance conduit 9, described control damper 5 is connected to ECU 7.ECU regulates the aperture of control damper 5 according to the information such as engine speed, controls exhaust gas particle enter capacity in suction tude 3, further Optimizing Combustion to reach.
