Description
Technical field
This utility model belongs to field of gas detection, and in particular to a kind of multi-functional airbag cleaning, sampling device.
Background technology
Atmosphere organic pollutant species is various, composition is complicated, and organic pollutant category contained by different industries, disparity items is not
One, and analysis method can not be exhaustive with pollutant emission standard, therefore often with volatile organic matter (VOCs), general volatile
The comprehensive evaluation factor as organic pollution such as Organic substance (TVOC) or NMHC (NMHC).NMHC conduct
《Discharge standard of air pollutants》An important Con trolling index in (GB16297-1996), it fires essentially from oils
Burning, solvent evaporation, waste incineration, waste refine and transport the aspects such as loss.With Chinese oil refining industry, petrochemical industry, automobile
The fast development of the industry such as industry and waste incineration and generating electricity, atmospheric pollution will be further serious, the monitoring to NMHC
To be more frequent.National environmental protection portion《With regard to the suggestion for further strengthening new period environmental monitoring work》With《The Supreme People's Court,
The Supreme People's Procuratorate is with regard to handling the explanation of environmental pollution criminal case law of application Tianjin some problem》Monitoring number is indicated respectively
According to as the basis and the importance of environmental pollution criminal case evidence for formulating Environment Protection Policy and measure.It can be seen that, it is ensured that prison
It is to realize environmental supervision and administration work legalization, quantification, scientific and Monitoring Data " accurate, fast, complete " mesh to survey data accuracy
Target top priority.
Find in the real work that NMHC is determined using gas chromatography, the non-methane of chronicity monitoring site
There is fluctuation or larger exceptional value in a big way in total hydrocarbon concentration；Methane concentration is higher than total hydrocarbon concentration in gas sample；The total hydrocarbon peak of gas sample
, there is hangover, bifurcated or multiple peaks in peak shape exception, contradicts with the principle for only going out a total hydrocarbon peak on void column.Excluding operating mode
On the premise of disturbing with oxygen peak, its reason does not install particulate filter or glass cotton when mostling come from sampling, power of sampling
Device cross-reference, does not take lucifuge measure to transport, and instrument system is contaminated, and calibration trace drafting effect is poor, and Quality Control measure is not
Entirely, sampling container cleaning performance is not good or preserves improper etc..Most of influence factor therein can be according to the standard operation of GB
Or Quality Control measure is eliminated, only sampling container cleanliness factor integrates the impact for quantitatively judging with result and not yet has to target compounds
Efficient and practicable solution.
At present, gas to be checked frequently with collection container be aluminum-plastic composite membrane, Devex films, Tedlar (PVF) film,
Teflon (FEP) film, Fluode (PCTFE) film gas sampling bags and Su Ma tanks etc., collection container high cost, if single use
Then high cost and increased environmental pollution.Therefore, collection container is typically repeated and uses, and prevents last time from collecting using cleaning is front needed
Gas residual contamination next time detection.The cleaning method for often using at present is the multiple weight by high pure nitrogen or de- hydrocarbon air
Preset brings cleaning airbag, but the method purification capacity is weak, cleaning performance is poor and there is limitation, is only applicable to concentration low, dry
Disturb the few sample airbag cleaning of thing.Because waste gas sample is in higher temperatures, humidity and pressure environment, some easy vaporized liquid
The high component of state hydro carbons, difficult volatility and chemism is easily collected in airbag, when ambient temperature is reduced suddenly with air-flow
It is adsorbed on airbag inwall, conventional cleaning method is difficult to the material by absorption on airbag inwall and washes.
