Description
Technical field
The utility model relates to automobile exhaust gas checking apparatus field, is specifically related to a kind of automotive check waste gas sampling device.
Background technology
Along with the development of auto industry and automobile pollution sharply increase, the pollutant of motor vehicle emission is one of consistent main pollution nuisance of urban atmosphere of generally acknowledging, has become serious social concern.Therefore, detect and control the concentration of automobile exhaust contaminant, becoming test item important in automotive check.
The pollutant of auto exhaust, mainly carbon monoxide (CO), hydrocarbon (HC), oxynitrides (NOx), sulfide (mainly SO
2), soot and other-a little objectionable impurities.Under identical operating mode, CO, HC and the NOx discharge of gasoline exhaust are larger than diesel engine, and therefore, current Abgasgesetz mainly limits the discharge capacity of CO, HC and NOx to gasoline engine.The pollution of diesel engine to air is light compared with gasoline engine, mainly produces carbon smoke pollution, and therefore Abgasgesetz mainly limits the smoke intensity of diesel exhaust gas.
When GB/T3845-1993 " the measurement slack speed method of pollutant of gasoline engine exhaust gas " specifies that pollutant of gasoline engine exhaust gas detects, NDIR (NDIR) should be adopted, and concrete regulation has been carried out to detection operating mode and trace routine.
Basic Cleaning Principle: CO, HC, NO and CO in auto exhaust
2deng gas, infrared ray is had respectively to the character absorbing certain wavelength, and have certain relation between the absorbed degree of infrared ray and exhaust gas concentration.Nondispersive infrared is exactly according to this principle, and namely the change of the certain wavelength infrared energy of waste gas absorption, detects the content of various pollutant in waste gas.When various gas mixes, this detection method has the impregnable feature of measured value.
Utilize the analyser that nondispersive infrared is made, both can make the single analysis instrument detecting separately CO or HC content, also can make the synthesis analyzer measuring these two kinds of gas contents.In exhaust, the concentration of CO directly measures, and the composition of HC emissions is very complicated, therefore the concentration conversion of various HC composition will be become normal hexane (n-C6H
14) concentration after be re-used as the measured value of HC concentration.
Carrying out analysis to vehicle exhaust to need to gather vehicle exhaust, is all manually utilize easy aspiration pump insertion gas outlet to extract a certain amount of gas the gas in aspiration pump to be entered in analyser at present again.This mode operational reliability is low, and hand sampling is unfavorable to the health of detection person, and the atomisation station gathered each time is different, also can have an impact to analysis result.
Therefore, need to design a kind of waste gas sampling device being specifically designed to analyser.
Utility model content
For solving the problems of the technologies described above, we propose a kind of automotive check waste gas sampling device, can reach the object that reliability is high, simple to operate, easy to use, work efficiency is high.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of automotive check waste gas sampling device, comprise sampling probe, sampling pump, filter cleaner, separator and conduit, described sampling probe is connected with described sampling pump, described sampling pump, described filter cleaner and described separator pass through tubes connection, this device gathers waste gas by sampling probe, conduit and pump from blast duct for vehicle, with filter cleaner and separator, carbon slag, dust and the moisture etc. in waste gas are removed again, only waste gas is sent into analytical equipment;
The stopple coupon of described sampling probe is draw-tube, described draw-tube is vertically provided with the backstay preventing draw-tube offside, and the length of described backstay is greater than the diameter of automobile exhaust pipe.
Compared with prior art, the utility model has the following advantages:
The utility model is when sampling, backstay is stuck in the end of automobile exhaust pipe just, make flexible stopple coupon go deep into draw exhaust in automobile exhaust pipe, through filter cleaner and separator, carbon slag, dust and the moisture etc. in waste gas are removed, then through Cemented filling in analytical equipment.Sample position is fixing, the error that whole sampling process can avoid manual operation to cause, and prevent widening of systematic error, improve the degree of reliability of test, meanwhile, sample rate is also significantly accelerated.
