Description
Technical field
The utility model relates to a kind of hyperchannel automobile exhaust purifier pick-up unit, the clarifier that this device is mainly used in being installed in the vehicle exhaust exhausr port carries out performance test, and by analyzing, relatively draw evaluation, the work efficiency during with raising people detection, screening clarifier to the clarifier changing effect.
Background technology
Along with The development in society and economy, the surge of the demand of automobile, the annual turnover of China's automobile is near 2,000 ten thousand, and the tail gas of motor vehicle emission simultaneously also becomes one of primary pollution source of atmosphere.In order to reduce the pollution that vehicle exhaust causes, China has formulated strict Abgasgesetz in succession.Wherein, catalytic cleaner is installed and reduces that the discharging of dusty gas is one of main solution in the waste gas in vehicle exhaust system.
The existing catalytic cleaner catalyzer of normally packing in purifier shell, the tail gas of during use automobile being discharged are introduced in the clarifier, and tail gas is discharged in the air after through the catalyzer purified treatment again.At present, the equipment that is used for the catalyst performance in the test purifier also relatively lacks, the general mode of artificial distribution that adopts is carried out performance test more, be about to the main harmful gas that CO, NOx, HC etc. constitute motor-vehicle tail-gas, be mixed with the vehicle exhaust of simulation by the physics control structure according to certain ratio, vehicle exhaust with simulation is input in the clarifier again, by the gas after handling through clarifier is carried out the content of harmful test, draw evaluation at last to performances such as clarifier inner catalyst activity, permanance.Though performances such as the activity that this traditional mode can more accurate ground evaluate catalysts, permanance, but, the simulated automotive tail gas of artificial preparation need dispose special source of the gas, flow control to gas requires very strict, the gentle physique control valve of its pipeline configuration piece is more complicated also, and higher to the gaseous mass purity requirement; In addition, the simulated automotive tail gas of artificial preparation is not the real emission gases of engine after all, and test result has certain limitation; In addition, most of catalyst test devices have only been used a reactant gas source, this single relatively sampling and sampling system, can only test out the catalytic performance of a kind of catalyzer under some working conditions at every turn, therefore the efficient of its screening catalyzer is very low, generally only is suitable for laboratory study and uses.
The utility model content
The utility model is at the existing deficiency that does not also have a cover to be specifically designed to the equipment that detects the automobile exhaust purifier performance at present, introduce and a kind ofly can under identical conditions, carry out performance test to a plurality of exhaust purifiers simultaneously, and the higher hyperchannel automobile exhaust purifier pick-up unit of detection efficiency.
The technical solution of the utility model: a kind of hyperchannel automobile exhaust purifier pick-up unit, it is characterized in that, comprise the gas piping that is used to connect the vehicle exhaust exhausr port, be parallel with some on the described gas piping by stop valve, exhaust purifier, air strainer, exsiccator and flow controller detection branch by constituting after the pipeline series connection, the output terminal of the flow controller in described each detection branch all is connected to exhaust gas analyzer, is connected with gas outlet at the output terminal of described exhaust gas analyzer; The pipeline that the output terminal of the stop valve in described each detection branch connects all passes temperature control box and corresponding exhaust purifier connection, and the pipeline that the output terminal of the exhaust purifier in described each detection branch connects all passes condenser and corresponding air strainer connection; Exhaust purifier in described each bar detection branch all is arranged in the insulation can.

More preferably, on described gas piping, also be connected with an exhaust branch pipe, surplus valve and sound suppressor are installed on described exhaust branch pipe.When the purpose that exhaust branch pipe is installed was that the tail gas force value of discharging when automobile surpasses setting value, vehicle exhaust overflowed by surplus valve, again emptying after sound suppressor is eliminated the noise.Unnecessary tail gas can be drained by exhaust branch pipe, prevent that the tail gas flow velocity from causing catalytic reaction insufficient too soon, influence testing result, the noise pollution when sound suppressor can also reduce exhaust simultaneously.
More preferably, also be parallel with a single channel detection branch that constitutes after by stop valve, three-way catalytic converter, the gentle series connection of pumps of air strainer on the described gas piping, the output terminal of described air pump connects the input end of exhaust gas analyzer.Single channel detection branch in the utility model is mainly used in test traffic and all bigger catalytic reactor of volume, enters the reacted gas of three-way catalytic converter after air strainer filters, again by testing in the air pump suction exhaust gas analyzer.
With respect to prior art, the utlity model has following beneficial effect:
1, be provided with a plurality of independently sense channels in the pick-up unit of the present utility model, each sense channel can be installed respectively and connect an exhaust purifier and carry out independently Performance Detection, thereby can reach the purpose of carrying out a plurality of exhaust purifier performance tests simultaneously, improved test, the efficient of screening, and in whole device, owing to adopted all-in-one-piece temperature control box and insulation can, therefore the environmental baseline of each sense channel is basic identical, this under identical conditions the resulting test result of test have more comparability, the evaluation result that therefore detects after the contrast is also more intuitive and reliable.
2, the vehicle exhaust that does not need complicated gas distribution pipeline and operation valve piece to generate simulation in the utility model, but directly adopt motor exhaust as detecting medium, and utilize the hyperchannel exhaust analyzer to carry out the testing result assessment, it both can detect in real time at the catalytic performance under the identical conditions the less exhaust purifier of a plurality of volumes, compare, also can test and assess in real time to the bigger three-way catalytic converter of full flow volume, its scope of application is wider, also helps improving the accuracy of testing result.
