Discharge gas, and then deficienter for the governance efficiency before and after administering and the measurement of concetration before improvement, and, market is existing
It is applied to administer compared with control system, being primarily present problems with is, 1, stability：Existing system stability is not typically high,
The analysis result causing in chromatography is not accurate.2nd, accuracy：Because before administering, gas concentration is big, constituent species
Many, relatively difficult in measurement.
Content of the invention
For the problem of existing measuring system, the present invention provides a kind of volatile organic contaminant to administer contrast post case, leads to
After crossing before detection is administered and administering, the total amount contrastive detection of gas can be governed efficiency and discharge capacity, concrete technical scheme
It is that a kind of volatile organic contaminant administers contrast post case, quantitative loop sampler, improvement before post case before including administering, improvement
Front detector, administer before chromatographic column, administer after post case, administer after quantitative loop sampler, administer after detector, administer after chromatograph
Post and switching valve it is characterised in that：Post case before improvement, administer after post case all by casing, heat-insulation layer, zone of heating structure from outside to inside
Become, interior for cavity, in cavity respectively fixing administer before chromatographic column, administer after chromatographic column, quantitative loop sampler, improvement before improvement
Front detector and administer after quantitative loop sampler, administer after detector be fixed on outside casing, the air inlet pipe of chromatographic column before improvement
With before improvement, quantitative loop sampler gas outlet is connected, escape pipe is connected with detector air inlet before improvement, chromatographic column after improvement
Air inlet pipe with administer after quantitative loop sampler gas outlet is connected, escape pipe is connected with detector air inlet after improvement, improvement
Front detector is connected with switching valve respectively with the air inlet pipe of detector after improvement.
Using method includes, step one, when need measurement administer before concentration when, before improvement, gas is entered into by switching valve
Fixed administer before in quantitative loop sampler, subsequently in chromatographic column before the internal empty improvement of post case before administering, before finally administering
Detector measures to gas concentration before administering；Step 2, when need measurement administer after concentration when, 1. measurement administer after total amount
Concentration, after improvement gas after threeway and switching valve enter partly into improvement the air inlet pipe of quantitative loop sampler, enter administer
Afterwards in chromatographic column after the internal empty improvement of post case, after finally administering, detector measures to total amount concentration after administering；2. measure
After improvement during concentration of component, after after improvement, gas carries out separating, enter in quantitative loop sampler by component by threeway, so
In chromatographic column after the internal empty improvement of post case after entrance is administered afterwards, finally by detector after administering, the component after improvement is carried out
Measurement；Step 3, by calculate administer before gas total amount concentration and administer after gas total amount concentration ratio, export and protect
Deposit governance efficiency, and export the composition component of gas after preservation is administered.
The solution have the advantages that, stable and reliable for performance, precision is good, efficiency high, low cost, install and debugging safety,
Convenient.
