Description
Technical field
The present invention relates to a kind of performance detecting system of automobile exhaust purifier, the system is mainly used in installed in automobile
The clarifier of tail gas exhaust outlet carries out performance test, and draws the evaluation to clarifier changing effect by analyzing, comparing, to carry
Operating efficiency when high people's detection, screening clarifier.
Background technology
With the development of the social economy, the demand of automobile surges, the annual turnover of China's automobile close to 20,000,000,
The tail gas of motor vehicle emission simultaneously also turns into one of primary pollution source of air.In order to reduce the pollution that vehicle exhaust is caused, China
Strict Abgasgesetz is formulated in succession.Wherein, catalytic cleaner is installed in vehicle exhaust system to pollute to reduce in waste gas
The discharge of gas is one of main solution.
Existing catalytic cleaner is typically to load catalyst in purifier shell, the tail gas for discharging automobile when using
Introduce in clarifier, tail gas is discharged into air again after catalyst cleaning processing.It is presently used for urging in test purifier
The equipment of agent performance also compares shortage, much more general to carry out performance test by the way of artificial distribution, i.e., by CO, NOx,
HC etc. constitutes the main pernicious gas of motor-vehicle tail-gas, is configured to the vapour of simulation by physical control structure according to certain ratio
Tail gas, then the vehicle exhaust of simulation is input in clarifier, have finally by the gas after the processing of purified device
The content measuring of evil material, draws evaluation this traditional mode of mouth to the performance such as catalyst activity, durability in clarifier
Although the performances such as activity, the durability of catalyst can be evaluated relatively accurately, the simulated automotive tail gas manually prepared is needed
Special source of the gas is configured, the flow control stopped to gas requires very strict, its pipeline configuration and gaseous mass control valve block
It is more complicated and higher to gaseous mass purity requirement:In addition, the simulated automotive tail gas manually prepared is not engine after all
Real discharge gas, test result has the limitation of a bandit;In addition, most of catalyst test devices have only used one
Reactant gas source, this single anti-sampling system of sampling relatively, can only test out a kind of catalyst in some operating mode bar every time
Catalytic performance under part, therefore the efficiency of its screening catalyst is very low, is typically suitable only for laboratory research and uses.
The content of the invention
The present invention is directed to now there is presently no a set of deficiency dedicated for detecting the equipment of automobile exhaust purifier performance,
Introduce one kind can be while carry out performance test, and the higher vapour of detection efficiency to multiple exhaust purifiers under identical conditions
Tailstock gas purifier performance detecting system.
Technical scheme:Performance detecting system for automobile tail gas purifier, it is characterised in that including for connecting vapour
The appendix of tail gas exhaust outlet, is parallel with some by stop valve, exhaust purifier, air filtration on the appendix
Device, drier and flow controller are by the detection branch that is constituted after placed in series, the flow in each detection branch
The output end of controller is all connected to exhaust gas analyzer, and blast pipe is connected with the output end of the exhaust gas analyzer;It is described each
The pipeline of the output end connection of stop valve in detection branch both passes through temperature control box and connected with corresponding exhaust purifier, described each
The pipeline of the output end connection of exhaust purifier in detection branch both passes through condenser and connected with corresponding air cleaner;Institute
The exhaust purifier stated in each bar detection branch may be contained within incubator.
Different catalyst can be prepared respectively in the present invention, in the exhaust purifier in each bar detection branch carrys out progressive
It can test, it is possible to the pattern worked simultaneously using a plurality of detection branch, because each bar detection branch is in temperature control box and condenser
In the presence of, the temperature of catalytic reaction is identical, can thus help people to compare test knot under same environmental conditions
The difference of fruit, so that fast and easy filters out the more excellent exhaust purifier of performance.
More preferably, an exhaust branch pipe is also associated with the appendix, overflow is installed on the exhaust branch pipe
Valve and silencer.When the purpose for installing exhaust branch pipe is the tail gas pressure value discharged when automobile more than setting value, vehicle exhaust
Overflowed, then emptied after being eliminated the noise through silencer by overflow valve.Unnecessary tail gas can be drained by exhaust branch pipe, prevent tail gas
Flow velocity causes catalytic reaction insufficient very much soon, influences testing result, while noise pollution when silencer can also reduce exhaust.
More preferably, be also parallel with the appendix one by stop valve, binary catalyst reactor, air cleaner and
The single channel detection branch constituted after air pump series connection, the output end of the air pump connects the input of exhaust gas analyzer.The present invention
In single channel detection branch be mainly used in testing flow and volume all larger catalytic reactors, into blue first catalytic reactor
After reacted gas is filtered through air cleaner, then by air pump be pumped into exhaust gas analyzer in tested.
Relative to prior art, the invention has the advantages that:
1st, multiple independent sense channels are provided with detecting system of the invention, each sense channel can be respectively mounted
One exhaust purifier of connection simultaneously carries out independent performance detection, so as to reach while carrying out multiple exhaust purifier performances
The purpose of test, improves test, the efficiency of screening, and in whole system, temperature control box as a result of monoblock type and
Incubator, therefore the environmental condition of each sense channel is essentially identical, it is this that resulting test knot is tested under identical conditions
The evaluation result that fruit is had more after comparativity, therefore detection contrast is also more intuitive and reliable.
2nd, the gas distribution pipeline and control valve block of complexity is not needed to generate the vehicle exhaust of simulation in the present invention, but directly
Connect using motor exhaust as detection medium, and using the progress testing result assessment of multichannel exhaust analyzer, it both can be with
The catalytic performance of the exhaust purifiers of multiple small volumes under identical conditions is detected in real time, compared, also can be to full stream
The larger three-way catalytic converter of amount volume is tested and assessed in real time, and its scope of application is wider, is also beneficial to improve testing result
Accuracy.
