Port valve reduces costs, more conducively the development of enterprise.
Detailed description of the invention
Fig. 1 is prior art construction schematic diagram；
Fig. 2 is schematic structural view of the invention.
In figure: 1 chromatographic column, 11 hydrogen flame detectors, 12 red press, 13 hydrogen generators, 2 valve bodies, 21 throttle parts.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 2, the present invention provides a kind of single detector list ten-way valve non-first total hydrocarbon benzene homologues online gc technology
Scheme: a kind of list detector list ten-way valve non-first total hydrocarbon benzene homologues online gc, including chromatographic column 1, heater strip, platinum resistance with
And the hydrogen flame detector 11 being connect with chromatographic column 1, the upper tube of hydrogen flame detector 11 connects air compressor machine 12, and hydrogen flame detects
The down tube of device 11 connects hydrogen generator 13, and the outlet side of hydrogen flame detector 11 is connected with total hydrocarbon column one and methane column one, and
The other end of total hydrocarbon column one and methane column one is connect with chromatographic column 1, and under normal circumstances, Normal practice is due to being different chromatography
Column cannot reach separation it is easy to appear different samples while appearance if conventionally using a detector
Purpose, if it is to be separated will carrier gas be tuned into different flow velocitys, detector sensitivity will receive influence again, and the testing time is very long；
The method that we invent uses special chromatographic column and vapour lock, reaches quick appearance, and sample separation is good, and test effect is more than double inspections
Survey device.
It further include the valve body 2 being connect with chromatographic column 1, and valve body 2 is connected separately with the import of sample gas and the outlet of sample gas, hydrogen flame
Benzene homologues one are additionally provided between detector 11 and chromatographic column 1, benzene homologues one are the pipeline for being passed through benzene homologues, subsequent benzene homologues
Two are also, and total hydrocarbon column one, methane column one and benzene homologues one are connect by triple valve one with hydrogen flame detector 11 respectively, valve body 2
Benzene homologues two for ten-way valve, and chromatographic column 1 are connect with valve body 2, eliminate a hydrogen flame detector 11 here, originally in addition
One hydrogen flame detector 11 is also logical benzene homologues, is changed to one here, saves cost, and the methane column two of chromatographic column 1 connects
On total hydrocarbon column two on to chromatographic column 1, and the end of total hydrocarbon column two is connect with valve body 2, and there are one six-way valve, chromatographic columns originally
1 benzene homologues two are connect with six-way valve, and then six-way valve is connect with sample air inlet and sample gas outlet respectively, save six here
Then benzene homologues two are connected on total hydrocarbon column two by port valve, thus effectively save a six-way valve, save cost, methane column
Two are connect by triple valve two with total hydrocarbon column two, facilitate connection, and hydrogen flame detector 11 between the import of sample gas by being provided with
Throttle part 21, throttle part 21 are needle-valve or vapour lock.
Principle is embodied: Normal practice is methane and total hydrocarbon uses carrier gas respectively, uses different basis weights ring respectively, is implemented
Sample introduction, benzene homologues also use independent carrier gas and a quantitative loop, thus inevitably need a ten-way valve 2 and one six
Chromatographic column 1 and vapour lock meeting needle-valve 21 is used herein in port valve, and total hydrocarbon column two and methane column two use the same carrier gas, and one double
Times quantitative loop, mean allocation air inflow guarantee that total hydrocarbon two and methane column two separate very well, effect and it is original, cost is lower.
