Description

Automobile tail vapour smoke purifier

The utility model relates to a kind of automobile tail vapour purification plant.

The most anury vapour of the motor purification plant of present automobile, the tail vapour that the motor operation produces directly is discharged in the environment by the motor steam-expelling port, and owing to being harmful to that oil inflame not exclusively produces, toxic substance is discharged in the lump with tail vapour environment is produced pollution.Although the service behaviour of the motor of various automobiles is good and bad different, it is low that the content of the harmful and noxious substance in the tail vapour of discharging has height to have, but along with rolling up that the development automobile of communication uses, the pollution that environment, particularly The Surroundings in Cities automobile tail vapour are produced more and more is serious, this threatens not only for city dweller's proper functioning and life, and people healthy also caused great infringement.

The purpose of this utility model provides that a kind of automobile, particularly car use, and can reduce harmful in the motor car engine discharging tail vapour, toxic substance content greatly, reduce the automobile tail vapour smoke purifier of automobile tail vapour environmental pollution.

Automobile tail vapour smoke purifier is installed base plate and is crossed central steam inlet pipe, an end closure the other end at steam vent place and be sealedly connected and fixed and have the tail vapour discharge pipe pipe joint the other end steam outlet pipe of installing on the base plate that is sealedly connected and fixed to constitute in that flame tube, an end on the base plate is installed by whole being connected of the installation base plate that had steam vent, sealing.Flame tube is sleeved on the central steam inlet pipe, and circumferentially there is vapor opening adjacent the company on the sidewall that base plate is installed of flame tube, and central steam inlet pipe peripheral wall surfaces and flame tube inner chamber wall surround the annular firing chamber.Steam outlet pipe is sleeved on the flame tube, and flame tube peripheral wall surfaces and steam outlet pipe inner chamber wall surround annular and go out the vapour passage, goes out the vapour passage and is communicated with the annular firing chamber of flame tube by the vapor opening on the flame tube.

The further improvement of automobile tail vapour smoke purifier is that axial screw type dividing plate is arranged in the annular firing chamber, automobile tail vapour passes through the annular firing chamber along the screw type passage after entering flame tube by central steam inlet pipe, make that tail steam flow journey by the annular firing chamber strengthens, the waiting time prolongs, be fully burned by harmful, the toxic substance of imperfect combustion generation in the tail gas and reduce harmful, toxic substance content in the tail vapour.

Further improving of automobile tail vapour smoke purifier be, the pollutant exhaust hole that has band to stop up on flame tube and the steam outlet pipe, by pollutant exhaust hole with in the burning cavity and go out the particular pollutant that deposits in the vapour passage and get rid of, to guarantee the normal purification operation of purifier.

Poisonous, harmful substance contents that the tail gas that utilizes automobile tail vapour smoke purifier that motor car engine is discharged is handled in the tail vapour that can make the automobile discharge by purification utensil significantly reduce, that actual road performance test shows, installs is poisonous in the tail vapour that automobile running is discharged behind the purifier, the harmful substance quality can reduce more than 90%, thereby greatly reduce the pollution of automobile tail vapour to environment.Secondly automobile tail vapour smoke purifier is installed in motor steam-expelling port place, the tail vapour that motor is discharged is discharged in the environment by exhaust steam pipe by purifier again, because the noise that the buffer function of purifier produced when making motor vehicle emission tail vapour reduces greatly, thus when having reduced automobile running to the noise pollution of environment.

Accompanying drawing is an embodiment of the present utility model, further specifies the utility model below in conjunction with embodiment.

Fig. 1 is an automobile tail vapour smoke purifier structural representation.

As shown in the figure, automobile tail vapour smoke purifier by with the installation base plate (1) of steam vent, sealing is whole to be connected and base plate is installed is crossed the central steam inlet pipe (3) at steam vent place, is sleeved on the end closure the other end on the central steam inlet pipe and is sealedly connected and fixed and flame tube (4) on the base plate is being installed, is being sleeved on the steam outlet pipe (5) that an end integral body on the flame tube is connected tail vapour discharge pipe pipe joint (7) and constitutes.Central authorities steam inlet pipe peripheral wall surfaces and flame tube inner chamber wall surround the annular firing chamber, and axial screw type dividing plate (6) is housed in the annular firing chamber, but automobile tail vapour is entered in the annular firing chamber by central steam inlet pipe and passes through the annular firing chamber along the spiral track.The contiguous installation on the base plate place side wall surface of flame tube circumferentially has vapor opening (2), and the automobile tail vapour by the annular firing chamber enters the annular that is surrounded by flame tube peripheral wall surfaces and steam outlet pipe inner chamber wall by vapor opening and goes out to enter in the exhaust steam pipe in the vapour passage and then by pipe joint and be discharged in the environment.Have pollutant exhaust hole (8) on the distolateral wall of flame tube adjacent central steam inlet pipe steam ouput, have pollutant exhaust hole (10) on the relative celebrating place side wall surface of steam outlet pipe with the flame tube pollutant exhaust hole, two pollutant exhaust holes are by plug stifled (9) sealing, open the stifled high speed tail steam flow of plug can with flame tube and steam outlet pipe by the granular sediments take the purification of combustion chamber out of and go out the vapour passage, to guarantee the purifier normal operation.Automobile tail vapour smoke purifier is installed in motor steam-expelling port place when using, the tail vapour that the motor operation produces is entered in the purifier by central steam inlet pipe, in tail vapour purification process, have surplus heat owing to containing, flame tube formation insulating lagging is incubated flame tube so annular goes out the vapour passage by the tail vapour in the steam outlet pipe.The high temperature tail vapour that is entered the annular firing chamber by central steam inlet pipe keeps high temperature, the unburned that contains in the tail vapour is harmful completely, further burning is complete for toxic substance thereby make, thereby harmful, toxic substance in the tail vapour of discharging are significantly reduced, and that actual driving proof is used is harmful in the tail vapour that discharges in the car running process behind the purifier, toxic substance content has reduced more than 90% before using.Because the noise that is produced during the buffer function motor vehicle emission tail vapour of purifier also obviously reduces.
