Abstract
The utility model relates to an automobile exhaust purification device, in particular to a waste gas purification device of a diesel engine. The waste gas purification device of the diesel engine comprises an exhaust pipe connected with the exhaust end of the engine, an air inlet pipe connected with the air inlet end of the engine and a silencer connected with the tail end of the exhaust pipe. A waste gas and particle separation device is installed between the exhaust pipe and the silencer and passes through an air filter to be connected with the air inlet pipe through a waste gas and particle conveying pipe. Tail gas generated by engine combustion flows in the waste gas and particle separation device through the exhaust pipe, the waste gas and particle separation device enables combustible insufficient-combusted particles with 0.1-0.5 mum diameter to be separated from the tail gas, and the separated tail gas is silenced by the silencer to be discharged in the air. The separated combustible particles are input in the air inlet pipe through the waste gas and particle conveying pipe. With a suction stroke of the diesel engine, the separated combustible particles are filtered by the air filter and then enter a combustion chamber to be combusted again when the air inlet pipe sucks fresh air so as to effectively solve the problem of emission pollution caused by insufficient combustion.
Description
Technical field
The utility model relates to a kind of purification plant, is specifically related to a kind of automobile exhaust gas purifying installation.
Background technique
When diesel vehicle from process at one's side the time, see the afterbody over-emitting black exhaust through regular meeting, this is exactly the particulate matter (PM: ParticulateMatter) of motor partial combustion discharging in fact.The particle that motor is discharged can be divided into three kinds of white cigarette, blue smoke and black smokes.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 all are not reach operating temperature and the too low institute of load causes because of motor, after motor reaches operating temperature and load and increases, and will Lock-out.Black smoke is then from fuel oil or machine oil, because the rough running of diesel engine, the heavy sulphur content in the fuel can not perfect combustions, enters atmosphere with effluent, its diameter is at about 0.1 ~ 0.5 μ m, not only cause the waste of the energy, and these small-particles are easy to be inhaled in the respiratory tract, cause serious disease.
The research of diesel engine vent gas reprocessing at present launches around eliminating NOx and PM, yet there are the mutual restriction relation in the formation of NOx and PM and content.Make great efforts to reduce one, must cause another pollutant to increase.When reducing NOx, adopt the high particulate trap of cost to catch, then by regeneration techniques combustion particle thing.Not only increase in this way the waste gas treatment cost, and caused the waste of the energy.
Summary of the invention
The utility model provides a kind of diesel engine exhaust purification plant of waste gas circulation burning in order to overcome the deficiency of above technology.
The technological scheme that its technical problem that overcomes the utility model adopts is:
This diesel engine exhaust purification plant, comprise the outlet pipe that is connected to the engine exhaust end and inlet end suction tude, be connected in the baffler of outlet pipe tail end, the exhaust gas particle segregating unit is installed between described outlet pipe and the baffler, and described exhaust gas particle segregating unit is connected in suction tude by the exhaust gas particle conveyance conduit 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 in its outlet end of suction tude and is connected in the exhaust gas particle conveyance conduit, also comprise outer diameter tube less than the waste gas exhaust pipe of the diameter of bore of exhaust-steam separator outlet end, described exhausting waste gas tubular portion sealing is inserted in the exhaust-steam separator outlet end and fixes.
Controlled in order to realize the exhaust gas particle amount, also comprise ECU and be arranged at control damper on the exhaust gas particle conveyance conduit 9 that described control damper is connected in ECU
The beneficial effects of the utility model are: the tail gas behind the engine combustion is by outlet pipe inflow exhaust gas particle sorting apparatus, the exhaust gas particle segregating unit is that 0.1 ~ 0.5 μ m burnable granule separates with the diameter that does not have sufficient combustion in the tail gas, and the tail gas after the separation is discharged in the atmosphere after by the baffler noise reduction.The burnable granule that separates is input in the suction tude by the exhaust gas particle conveyance conduit, when following diesel engine in suction stroke, to suck fresh air by suction tude the burnable granule that separates is entered the firing chamber after air filter filters and burn again, with the insufficient exhaust emission that causes of effective solution burning.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1. air filter 2. outlet pipes 3. suction tude 4. exhaust-steam separators 5. control dampers 6. baffler 7.ECU 8. waste gas exhaust pipes 9. exhaust gas particle conveyance conduits.
Embodiment
Be described further below in conjunction with 1 pair of the utility model of accompanying drawing.
This diesel engine exhaust purification plant, comprise the outlet pipe 2 that is connected to the engine exhaust end and inlet end suction tude 3, be connected in the baffler 6 of outlet pipe 3 tail ends, between described outlet pipe 2 and the baffler 6 the exhaust gas particle segregating unit is installed, described exhaust gas particle segregating unit is connected in suction tude 3 by exhaust gas particle conveyance conduit 9 through air filter 1.Tail gas behind the engine combustion is by outlet pipe 3 inflow exhaust gas particle sorting apparatus, the exhaust gas particle segregating unit is that 0.1 ~ 0.5 μ m burnable granule separates with the diameter that does not have sufficient combustion in the tail gas, and the tail gas after the separation is discharged in the atmosphere after by baffler 6 noise reductions.The burnable granule that separates is input in the suction tude 3 by exhaust gas particle conveyance conduit 9, when following diesel engine in suction stroke, to suck fresh airs by suction tude 3 burnable granule that separates is entered the firing chamber after air filter filters and burn again, with the insufficient exhaust emission that causes of effective solution burning.
The exhaust-steam separator 4 that above-mentioned exhaust gas particle segregating unit is pipeline twist, the inlet end of described exhaust-steam separator 4 is connected in suction tude 3 its outlet end and is connected in exhaust gas particle conveyance conduit 9, also comprise outer diameter tube less than the waste gas exhaust pipe 8 of the diameter of bore of exhaust-steam separator 4 outlet end, described waste gas exhaust pipe 8 parts sealing is inserted in exhaust-steam separator 4 outlet end and fixes.When the tail gas after the burning enters exhaust-steam separator 4 from outlet pipe 8, because 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, because the outer diameter tube of waste gas exhaust pipe 8 is less than the diameter of bore of exhaust-steam separator 4 outlet end, therefore the space inflow exhaust gas particle transport pipeline 9 of burnable granule between waste gas exhaust pipe 8 and exhaust-steam separator 4 after separating, remaining waste gas directly flows into baffler 6 by waste gas exhaust pipe 8.
Also comprise ECU 7 and be arranged at control damper 5 on the exhaust gas particle conveyance conduit 9, described control damper 5 is connected in ECU 7.The aperture that ECU regulates control damper 5 according to information such as engine speed enters capacity in the suction tude 3 to reach the control exhaust gas particle, further optimizes burning.
