Abstract
The utility model discloses an on-line component analysis device for rock core output liquid, which is designed to realize automatic sampling and sample introduction of the rock core output liquid and analyze and record components of the rock core output liquid on line. An output liquid outlet of the analysis device is communicated with a buffer pool; one path of the buffer pool is communicated with a blow-down pipe and the other path thereof is communicated with an injection pump; the other end of the injection pump is communicated with a sample gasification chamber in a closed container shape; one end of a heater in the sample gasification chamber is communicated with the injection pump and the other end thereof is communicated with an electric control multiport valve; and valve locations, switched under the control of a controller, of the electric control multiport valve are connected with a quantitative pipe, a carrier gas pipeline, a gas chromatograph and a multiport valve blow-down pipe. The device can automatically collect the rock core output liquid for on-line component analysis; the fixed quantity sampling every time is realized by the quantitative pipe; the repeated measuring precision can be ensured; and the unattended automatic sampling and sample introduction are realized during an experiment.
Description
Technical field
The utility model relates to the online proximate analysis device of a kind of rock core output liquid, belongs to the core analysis technical field.
Background technology
In core analysis test, adopt gas chromatograph to analyze the component of rock core output liquid usually, gather sample to be analyzed with containers such as syringe are artificial, manual injecting chromatograph then, this is a kind of analysis experiment method based on manually-operated.Usually contain liquid such as toluene, methenyl choloride or methyl alcohol in the rock core output liquid, the volatility height, toxicity is big, and is inflammable and explosive, and the experimenter is when sampling and commentaries on classics sample, and personal safety is on the hazard.When carrying out continuous sampling in 24 hours test, experimenter's duty fatigue is easy to occur maloperation.
Summary of the invention
The purpose of this utility model is to provide a kind of rock core output liquid online proximate analysis device, and it can realize unattended automatic sampling sample introduction in the experimentation, on-line analysis and record rock core output liquid component.
Concrete technical scheme of the present utility model is as follows:
The output liquid outlet of this analysis device is communicated with cache pool, and cache pool one tunnel is communicated with blow-down pipe, and one the tunnel is communicated with syringe pump, and the syringe pump other end is communicated with the sample vaporizer of closed container shape.Indoor well heater one end of sample gasification is communicated with syringe pump, and the other end is communicated with automatically controlled multiport valve.Each valve position of being controlled the automatically controlled multiport valve that switches by controller connects quantity tube, gas-carrier pipeline, gas chromatograph and multiport valve blow-down pipe respectively.
This device can be gathered rock core output liquid automatically, carries out online proximate analysis, relies on quantity tube to realize each fixed amount sampling, can guarantee the replication precision, realizes unattended automatic sampling sample introduction in the experimentation.
Description of drawings
Fig. 1 is the online proximate analysis apparatus structure of rock core output liquid synoptic diagram.
Embodiment
With reference to Fig. 1 embodiment of the present utility model is further specified:
Embodiment:
This analysis device comprises output liquid outlet 1, cache pool 2, syringe pump 3, well heater 4, gas-carrier pipeline 5, automatically controlled multiport valve 6, quantity tube 7, gas chromatograph 8, controller 9, multiport valve blow-down pipe 10, sample vaporizer 11 and blow-down pipe 12:
Output liquid outlet 1 is communicated with cache pool 2, and cache pool 2 one tunnel is communicated with blow-down pipe 12, a tunnel and is communicated with syringe pump 3, and syringe pump 3 other ends are communicated with the sample vaporizer 11 of closed container shape; Well heater 4 one ends in the sample vaporizer 11 are communicated with syringe pump 3, and the other end is communicated with automatically controlled multiport valve 6; Each valve position of controlling the automatically controlled multiport valve 6 that switches by controller 9 connects quantity tube 7, gas-carrier pipeline 5, gas chromatograph 8 and multiport valve blow-down pipe 10 respectively.
Cache pool 2 is provided in a side of the low capacity storage transition apparatus that output liquid exports 1 place, and rock core output liquid obtains renewal by the new liquid of output in the continuous inflow pond.Syringe pump 3 is used for the output liquid of suction and pumping test usefulness.Well heater 4 is used to vapourised liquid sample that the temperature support is provided, heated sample vaporizer 11, and the liquid sample that vaporization pumps into for automatically controlled multiport valve 6 insulations, prevents gas condensation in quantity tube 7 and automatically controlled multiport valve 6.Gas-carrier pipeline 5 is used for vaporized sample is blown to quantity tube 7 or multiport valve blow-down pipe 10.Automatically controlled multiport valve 6 is used for connecting and switching gas-carrier pipeline 5, quantity tube 7 and gas chromatograph 8, and the control carrier gas is blown sky quantity tube 7, carrier gas and blown the samples that sky chromatograph 8 and carrier gas blow in the quantity tube 7 and enter gas chromatograph 8.Controller 9 is used for realizing overall situation control and the data acquiring and recording of analytical equipment.
On-test and output liquid appears after, the output liquid of a constant volume is pumped to sample vaporizer 11 in the controller 9 instruction syringe pumps 3 suction cache pools 2.Behind output liquid heater via 4 high-temperature gasifications, be blown into quantity tube 7 by gas-carrier pipeline 5.Controller 9 switches valve position, sends trigger pip to gas chromatograph 8, makes its collection and record data, subsequently, the branch make-up carrier gas of gas chromatograph 8 flows to automatically controlled multiport valve 6, and the gaseous sample that quantity tube 7 collects is brought in the chromatographic column, and air feed chromatography 8 detects the peak.Behind the automatic storage data of setting of time, controller 9 is controlled syringe pump 3 suctions again, and above-mentioned steps is carried out in circulation.
