Abstract
The invention relates to the field of motor vehicle tail gas purifying, in particular to a tail gas particle washing centrifugal device. The tail gas particle washing centrifugal device comprises a gas inlet pipe connected to the outlet of a silencer, and a cylindrical separating tank connected with the gas inlet pipe. The gas inlet pipe is arranged at the upper portion of the side wall of the separating tank and arranged in the tangential direction of the side wall, an exhaust pipe installed in the axial direction of the separating tank is arranged above the separating tank, the inlet of the exhaust pipe extends into the separating tank, washing water is arranged at the bottom of the separating tank, the bottom of the separating tank is in an inverted cone shape, and a sprayer is arranged at the conical tip position and communicated with the gas inlet pipe through a branch pipe. The tail gas particle washing centrifugal device with the technical scheme can effectively separate and remove particles in the tail gas and can reduce the temperature of the tail gas.
Description
Technical field
The present invention relates to motor vehicle tail-gas purifying field, relate in particular to a kind of exhaust particulate washing centrifugal device.
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.At present by the quality improving catalytic reactor, EGR Technology, engine technology, fuel qualities improve air, particularly adopt three-way catalytic converter.Concrete way is that 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, makes 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 exhaust particulate to wash centrifugal device, can effectively be separated and remove the particle in tail gas, and reduce the temperature of tail gas.
Exhaust particulate washing centrifugal device in this programme, include the suction tude being connected to muffler outlet, and the cylindrical shape knockout drum to be connected with suction tude, tangent direction above the sidewall that described suction tude is arranged on knockout drum and along sidewall is arranged, installation outlet pipe is in its axial direction provided with above described knockout drum, the entrance of outlet pipe stretches in knockout drum, wash water is equipped with in the bottom of knockout drum, in an inverted cone bottom knockout drum, the position of cone point is provided with shower nozzle, and described shower nozzle is connected in suction tude by arm.
The exhaust particulate of this programme washing centrifugal device is adopted to have following advantage: after tail gas is discharged from silencing apparatus, it is by three-way catalyst process, harmful gas is less, but still containing exhaust particulate, major part tail gas enters knockout drum along suction tude, fraction tail gas enters shower nozzle along arm, shower nozzle is heaved a large amount of water smoke and is filled the air in knockout drum from wash water, and the tail gas that suction port enters rotates deceleration along knockout drum sidewall, particle in this part tail gas is combined with water smoke and becomes heavy, then be thrown to knockout drum sidewall to separate, clean tail gas enters air after knockout drum discharged by outlet pipe.
The sidewall of described outlet pipe is provided with helical baffles, and the direction of spiral is identical with suction tude direction, and such arranging can guide tail gas better along knockout drum sidewall rotating centrifugal, makes the particle that is combined with water smoke more easily separated.
The top of described knockout drum is provided with a water-supplying mouth, and this water-supplying mouth is connected to water tank, and such arranging can make wash water obtain certain compensation, avoids causing wash water not enough because the tail gas of high temperature takes away wash water.
Be provided with sewage draining exit bottom described arm, such arranging can allow wash water emit timely after by a large amount of particle contaminations, avoids particle to gather in knockout drum.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment of the present invention exhaust particulate washing centrifugal device.
Embodiment
Below by embodiment, the present invention is further detailed explanation:
Reference character in Figure of description comprises, suction tude 1, knockout drum 2, outlet pipe 3, deflection plate 4, shower nozzle 5, arm 6, sewage draining exit 7.
The exhaust particulate of embodiment washes centrifugal device as shown in Figure 1: include the suction tude 1 being fixed on muffler outlet by Flange joint, and the cylindrical shape knockout drum 2 to weld with suction tude 1, tangent direction above the sidewall that suction tude 1 is arranged on knockout drum 2 and along sidewall is arranged, installation outlet pipe 3 is in its axial direction provided with above knockout drum 2, the lower end of outlet pipe 3 is stretched in knockout drum, the sidewall of outlet pipe 3 is provided with helical baffles 4, the direction of the spiral of deflection plate 4 is identical with suction tude 1 direction, to guide tail gas better along knockout drum 2 sidewall rotating centrifugal, wash water is equipped with in the bottom of knockout drum 2, in an inverted cone bottom knockout drum 2, the position of cone point is provided with shower nozzle 5, shower nozzle 5 camber is arranged, and flooded by wash water, preferred distance is shower nozzle 5 is 1cm with wash water water surface spacing, shower nozzle 5 is connected in suction tude 1 by arm 6.Make the particle that is combined with water smoke more easily separated, the top of knockout drum 2 is provided with a water-supplying mouth 8, this water-supplying mouth 8 is connected to water tank by flanged pipe, certain compensation is obtained to make wash water, finally bottom arm 6, be provided with sewage draining exit 7, so that wash water can be emitted timely, particle is avoided 2 to gather in knockout drum.
The exhaust particulate washing centrifugal device of this programme is work like this: after tail gas is discharged from silencing apparatus, be divided into two parts, major part tail gas enters knockout drum 2 along suction tude, fraction tail gas enters shower nozzle 5 along arm, shower nozzle 5 is heaved a large amount of water smoke and is filled the air in knockout drum 2 from wash water, and the tail gas that suction port enters rotates deceleration along knockout drum 2 sidewall, particle in this part tail gas is combined with water smoke and becomes heavy, then be thrown to knockout drum 2 sidewall to separate, clean tail gas enters air after knockout drum 2 discharged by outlet pipe 3.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the embodiment in specification etc. record the content that may be used for explaining claim.
