It is including exhaust gas collection pipe, support, fan, cowling panel, grain catcher, plenum chamber, urea tank and injection system and the jet that can stretch out and draw back, on the well position support of exhaust gas collection pipe, its both ends are connected respectively by measuring vehicle blast pipe and fan, the outlet pipe of fan is equipped with the cowling panel at well intersegmental part, at the intramural grain catcher of end -to -end connection plenum chamber side, the upper portion of plenum chamber is equipped with the jet, and this jet management is said and is linked to each other with urea tank and injection system. Compared with the prior art, the utility model discloses the exhaust gas collection union coupling starts the fan and just can collect tail gas to the blast pipe to the processing can all be collected to the tail gas of gasoline car, diesel vehicle, neither influences detection line normal operating, has also realized the target of testing process environmental protection, has also guaranteed that measurement personnel avoids tail gas and pollutes simultaneously.
Description
Technical field
The utility model belongs to field of environment engineering technology, specifically, relates to a kind of exhaust collection treating apparatus for vehicle inspection and test station.
Background technology
Motor vehicle must carry out annual test and Tail gas measuring according to the rules, commerial vehicle also needs to carry out inspect on colligated-function, the vehicle fleet size carrying out detecting is needed to increase year by year, tail gas number ratio is produced larger in testing process, adverse influence is caused to the environment of surrounding, measuring station staff is in the environment of this high pollution every day simultaneously, very unfavorable to health.From control atmosphere pollution and the angle protecting labourer's health, the tail gas that must produce tested vehicle must carry out collection process.And existing vehicle exhaust collection and treatment device adopts armstrong's patent to be clamped in the exhaust pipe mouth of engine exhaust system mostly, sometimes two people's cooperations are needed just can to clamp, waste time and energy, efficiency is lower, and poorly sealed, interface position leakiness gas, the waste gas collected is usually untreated with regard in the direct air entered by pipeline outside workshop, contaminated environment, does not meet the requirement that national energy-saving reduces discharging yet.
Summary of the invention
For solving the problems of the technologies described above, the utility model provide a kind of easy for installation, be easy to operate the exhaust collection treating apparatus for vehicle inspection and test station.
A kind of exhaust collection treating apparatus for vehicle inspection and test station described in the utility model, described exhaust collection treating apparatus comprises retractable exhaust collection pipe 1, support 2, blower fan 3, cowling panel 4, grain catcher 5, plenum chamber 6, urea tank and spraying system 7 and jet 8; On the middle position support 2 of described exhaust collection pipe 1, its two ends connect detected blast duct for vehicle and blower fan 3 respectively; The outlet of described blower fan 3 is provided with cowling panel 4 in inside, connects the grain catcher 5 in plenum chamber 6 sidewall at end; The top of described plenum chamber 6 is provided with jet 8, and this jet 8 is connected with urea tank and spraying system 7 by pipeline.
A kind of exhaust collection treating apparatus for vehicle inspection and test station described in the utility model, described exhaust collection pipe 1 arrival end is horn mouth.
A kind of exhaust collection treating apparatus for vehicle inspection and test station described in the utility model, the upper and lower on the right side of described plenum chamber 6 is respectively equipped with air bleeding valve 9 and discharge outlet 10.
A kind of exhaust collection treating apparatus for vehicle inspection and test station described in the utility model, the air-tightness that described connection is band sealing ring connects.
Compared with prior art, the exhaust collection pipe of the exhaust collection treating apparatus for vehicle inspection and test station described in the utility model is connected to blast pipe, start blower fan and just can collect tail gas, and the tail gas of gasoline car, diesel vehicle can carry out collection process, neither affect detection line normally to run, also achieve the target of testing process environmental protection, also ensure that testing staff is from tail gas pollution simultaneously.This utility model global design is novel, easy for installation, is easy to operation.
Accompanying drawing explanation
Fig. 1: for the exhaust collection treating apparatus figure of vehicle inspection and test station; Exhaust collection pipe-1, support-2, blower fan-3, cowling panel-4, grain catcher-5, plenum chamber-6, urea tank and spraying system-7, jet-8, air bleeding valve-9, discharge outlet-10.
Detailed description of the invention
Below in conjunction with specific embodiment, the exhaust collection treating apparatus for vehicle inspection and test station described in the utility model is described further, but protection domain of the present utility model is not limited to this.
Embodiment 1
For an exhaust collection treating apparatus for vehicle inspection and test station, comprise retractable exhaust collection pipe 1, support 2, blower fan 3, cowling panel 4, grain catcher 5, plenum chamber 6, urea tank and spraying system 7 and jet 8; On the middle position support 2 of described exhaust collection pipe 1, its two ends connect detected blast duct for vehicle and blower fan 3 respectively; The outlet of described blower fan 3 is provided with cowling panel 4 in inside, connects the grain catcher 5 in plenum chamber 6 sidewall at end; The top of described plenum chamber 6 is provided with jet 8, and this jet 8 is connected with urea tank and spraying system 7 by pipeline.
Exhaust collection pipe 1 connects detected blast duct for vehicle, start blower fan 3 and urea injection system 7, tail gas is collected while detecting, tail gas is after cowling panel 4, gas flow is stablized, enter grain catcher 5, remove particle in tail gas, wherein particle is maximum to harm, gas through grain catcher is finally retained in plenum chamber 6, and urea solution spraying system can spray vaporific urea solution by jet 8, carries out chemical reaction with the tail gas be trapped in plenum chamber, produce nitrogen and water, the remaining nitrogen oxide in removing tail gas.The nitrogen produced after reaction can be accumulated, and when the pressure in plenum chamber is greater than atmospheric pressure, in case, gas can be discharged by air bleeding valve 9, and the chemical reaction in case can produce certain moisture, needs regularly by discharge outlet 10 draining.Exhaust collection pipe 1 end is horn mouth, and diameter slightly larger than blast pipe, and has good retractility, heat resistance, also should have good air-tightness.Quickly and easily exhaust collection pipe can be connected to blast pipe.Each connecting portion has sealing ring, prevents exhaust gas leak, ensures higher vent gas treatment effect.
Compared with prior art, the exhaust collection pipe of the exhaust collection treating apparatus for vehicle inspection and test station described in the utility model is connected to blast pipe, start blower fan and just can collect tail gas, and the tail gas of gasoline car, diesel vehicle can carry out collection process, neither affect detection line normally to run, also achieve the target of testing process environmental protection, also ensure that testing staff is from tail gas pollution simultaneously.This utility model global design is novel, easy for installation, is easy to operation.
