Detailed Description
In order to make the technical solutions and advantages of the present invention clearer, the following will describe embodiments of the present invention in further detail with reference to the accompanying drawings.
In one aspect, an embodiment of the present invention provides an apparatus for separating gas from a liquid under pressure, as shown in fig. 1, the apparatus comprising: an injector 1, a sampler 2 and a stripper 3 which are communicated in sequence through connecting pipelines.
Wherein, sampler 2 includes: a quantitative sampling tube 201, an inlet valve 202 and an outlet valve 203 respectively arranged at two ends of the quantitative sampling tube 201.
The stripper 3 comprises: a stripping pipe 301 communicated with the connecting pipeline, an air outlet pipe 302 communicated with the upper part of the stripping pipe 301, an air inlet pipe 303 communicated with the bottom of the stripping pipe 301, and a sieve plate 304 arranged at the lower part of the inner cavity of the stripping pipe 301.
The syringe 1 contains a solution, and the quantitative sampling tube 201 contains a pressurized liquid.
The device provided by the embodiment of the invention can be used for separating gas from liquid under pressure, when the device is applied, the inlet valve 202 is kept in a closed state, the outlet valve 203 is opened, and part of liquid under pressure in the quantitative sampling tube 201 enters the stripping tube 301 through the connecting pipeline for decompression flash evaporation to obtain flash evaporation gas, meanwhile, carrier gas is introduced through the gas inlet tube 303, and the flash evaporation gas is taken out of the stripping tube 301 by the carrier gas and is discharged and enriched through the gas outlet tube 302. Keeping the carrier gas continuously introduced, opening the inlet valve 202, pushing the analytic solution into the quantitative sampling tube 201 through the injector 1, allowing the analytic solution and the rest part of the liquid in the quantitative sampling tube 201 to enter the stripping tube 301 through the connecting pipeline for stripping treatment to obtain a stripping gas, carrying the stripping gas out of the stripping tube 301 through the carrier gas, and discharging and enriching the stripping gas through the gas outlet pipe 302. It can be seen that the enriched gas contains not only the gas component flashed off under reduced pressure but also the gas component remaining in the liquid after reduced pressure. Since the composition of the carrier gas is determined, the content of the above gas components separated from the enriched gas can be easily determined, so that accurate quantification of the content of the gas components in the pressurized liquid can be realized, and the process design and equipment selection for processing the gas components can meet the actual requirements.
It can be understood that the stripping treatment of the flash evaporation gas and the gas remained in the decompressed liquid by the carrier gas not only improves the stripping efficiency, but also can fully enrich the dissolved gas components in the pressurized liquid and improve the measurement accuracy.
In the case of the sampler 2, the volume of the quantitative sampling tube 201 is determined, that is, the content of the pressurized liquid in the quantitative sampling tube 201 is determined, so that the content of the gas component in the pressurized liquid can be easily determined when the content of all the gas components contained therein is obtained.
In the embodiment of the present invention, the quantitative sampling tube 201 may be a metal hose, and an inlet valve 202 and an outlet valve 203 are respectively installed at two ends of the metal hose. In the non-operating state, both the inlet valve 202 and the outlet valve 203 are in a closed state, i.e., a normally closed state.
In order to avoid errors in the determination of the gas composition content by the material of the sampler 2, e.g. gas penetrating into the inner wall of the sampler 2, etc., the sampler 2 is passivated with an pressurised liquid before use, e.g. the sampler 2 may be allowed to store the pressurised liquid for several hours, e.g. 10-24 hours, e.g. 12 hours, etc., before use. Further, prior to use, the liquid-passivated probe 2 is also passivated with a resolving liquid, e.g. the resolving liquid is stored for several hours, e.g. 10-24 hours, e.g. 12 hours, etc. with the liquid-passivated probe 2.
After the passivation process, a quantitative sampling tube 201 is used to store a quantitative amount of pressurized liquid for separating gas therefrom.
In view of the convenience of operation, as shown in fig. 1, the apparatus provided by the embodiment of the present invention further includes: a first support 4, wherein the first support 4 is adapted to support the sampler 2.

Further, as shown in fig. 1, the apparatus provided in the embodiment of the present invention further includes: a second support 5, the second support 5 being for supporting the stripper 3 to further improve the convenience of operation.
As an example, the second support 5 is a support platform with a storage compartment for receiving the stripping tube 301 and the inlet tube 303.
It is understood that the structure of the storage tank is determined according to the structure and arrangement relationship of the stripping pipe 301 and the air inlet pipe 303, so as to ensure that the stripping pipe 301 is in a vertical state and the air inlet pipe 303 is kept stable.
The inlet pipe 303 may include an upper horizontal section, a main vertical section, a lower horizontal section, and a mouthpiece vertical section connected in series. Wherein the interface vertical section is in communication with the bottom of the stripping tube 301 to facilitate the carrier gas to smoothly enter the stripping tube 301 without backflow.
In an embodiment of the invention, the sieve plate 304 is used to generate bubbles of gas as the carrier gas passes through, which contact the liquid under pressure to carry the gas out of it. The sieve plate 304 has a plurality of sieve holes, for example, 20-40 sieve holes, for example, 30 sieve holes, wherein the pore diameter of the sieve holes is 0.5 mm-1 mm, so as to achieve a good gas carrying effect.
In order to provide sufficient space for the reduced pressure flash and stripping process, in the present example, outlet pipe 302 is spaced 30 cm from the bottom of stripping pipe 301. Meanwhile, in order to obtain a better gas carrying effect, the distance between the sieve plate 304 and the bottom of the stripping pipe 301 is 3.5 cm.
In the embodiment of the invention, the inlet valve 202, the quantitative sampling tube 201 and the outlet valve 203 all require the pressure-bearing capacity to be not less than 15 Mpa. The connection line may be a hose, for example of teflon, which is inert and of high strength, ensuring an accurate measurement of the gas content. The stripping tube 301, the inlet tube 303 and the sieve plate 304 may all be of quartz. The outlet pipe 302 may be vertically connected to and communicated with the upper side wall of the stripping pipe 301. Furthermore, the top opening of the stripping tube 301 is provided with a sealing cap through which the end of the connecting line is sealed into the stripping tube 301 to ensure that the gas is collected in its entirety. For example, the sealing cap may be screwed with the stripping tube 301, and a sealing member may be disposed therebetween, or the sealing cap may be a rubber plug inserted into the top opening of the stripping tube 301.
