Description
Technical field
The utility model relates to automobile VOC detection technique field, specifically a kind of VOC pick-up unit for automobile green reclaim.
Background technology
In VOC and car, air and car inside gadget material organic volatile detect, automobile all will be tested VOC when dispatching from the factory or scrap recovery, the volatile organic matter that automobile distributes is very large to the harm of people, when the VOC in car reaches finite concentration, in short time, people can feel headache, feel sick, tic is there will be time serious, and the liver of people can be hurt, kidney, brain and nervous system, domestic and Europe at present, beautiful, daily there is no the national standard of vehicle air quality, regulation, but there is data to show the control of external Main Auto company for in-car air quality, mainly through what realize the management of auxiliary component, when VOC in car reaches finite concentration, in short time, people can feel headache, feel sick, tic is there will be time serious, and the liver of people can be hurt, kidney, brain and nervous system, interior space is narrow and small, pollution level is large, the leakproofness of automobile is very strong, door and window is closed as a rule, be unfavorable for the diffusion of harmful gas, automobile is mobile traffic, large with extraneous convective heat exchange amount, the change of outside climatic condition greatly, the control difficulty of the conditions such as temperature is strengthened, vehicle glass door and window area occupied is large, long-time exposure in the sun, vehicle interior temperature amplitude of variation is larger.At high temperature, parts in car, and objectionable impurities in ornament materials is more out volatile, in car, the density of population is large, has increased the weight of pollution.Existing VOC test all adopts sampling to detect, and whole testing process is discontinuous, and intermediate link easily causes sampling contaminated, impact test effect.
Therefore, design to detect VOC and have good continuity for overcoming the deficiency of above-mentioned technology, avoid detecting sample contaminated, ensure a kind of VOC pick-up unit for automobile green reclaim of accuracy of the data detected, inventor's problem to be solved just.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of VOC pick-up unit for automobile green reclaim, and it detects VOC good continuity, avoids detecting sample contaminated, ensure the accuracy of the data detected, have extraordinary practical value.
The utility model solves the technical scheme that its technical matters adopts: a kind of VOC pick-up unit for automobile green reclaim, it is characterized in that: device comprises sampling mechanism, pre-service mechanism and testing agency, sampling mechanism is connected with processing mechanism, and pre-service mechanism is connected with testing agency.
Further, described sampling mechanism comprises sampling end, sample conduit, sampling pipe, Constant flow sample pump, and sample conduit one end is sampling end, and the sample conduit other end is Constant flow sample pump, is provided with sampling pipe in the middle of sampling end and Constant flow sample pump.
Further, described pre-service mechanism comprises sampler bag, source nitrogen, constant temperature oven, and described sampler bag is arranged in constant temperature oven, and sampler bag is connected with source nitrogen.
Further, described testing agency can survey spectrometer for gas phase.
Further, the quantity of described sampling end is at least two, and the quantity of the sample conduit be connected with sampling end is at least two.
The beneficial effects of the utility model are:
1, the utility model passes through the connection of three parts of sampling mechanism, pre-service mechanism, testing agency, the detection of the VOC to automobile is made to have more continuity, all continuity is achieved with detecting from the pre-service sampling sample of sample, guarantee sample is contaminated, ensure that the accuracy of the effect of detection simultaneously.
