Description
Technical field
It the utility model is related to normal temperature and pressure gas solubility measure device.
Background technology
The field that the solubility of gas in a liquid is related to is very extensive, such as：Chemical process design, Environmental Chemistry, biology
Medical technology, biophysics, geochemistry etc., it is industrial very important basic data.The solubility of gas is most
It is by vascular unloading technique experimental test, due to the solubility very little of general gas flow in a liquid, is brought to experiment very big
Difficulty, result of the test are not easy to measure accurately.Existing test device includes complicated solvent purification device and excessive switching
Head and valve, not only device airtight test is numerous and diverse, and pipeline cleaning is difficult.
The content of the invention
It is to be solved in the utility model to be to provide normal temperature and pressure gas solubility measure device, to realize at normal temperatures and pressures
The test of gas solubility, solve existing instrument test precision not enough and sealing technical problem.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：Normal temperature and pressure gas solubility measure dress
Put, including balance cylinder, balance cylinder upper end are connected by the first pipeline with vavuum pump, and the first valve is provided with the first pipeline,
Top cover is installed in balance cylinder's opening, pressure gauge is installed in top cap central, balance cylinder bottom passes through second pipe and cylinder
Connection, is provided with the second valve and the 3rd valve, the second pipe between the second valve and the 3rd valve on second pipe
On be communicated with the 3rd pipeline, the 4th valve is installed on the 3rd pipeline, support is fixedly connected with cylinder outer wall, in support
Displacement monitors are installed, displacement monitors thimble is resisted against on cylinder piston rod.
The beneficial effects of the utility model are：The utility model can take out the mode of pressure first by remaining in solution using vacuum
Gas evolution, then entered by gas from solution bottom, fully gas is dissolved in solution；On the other hand, this practicality is new
Type only can need to change gas in piston container into pure gas (such as O to different type gas test2、CO2Deng), it is operated
Mode is simple and efficient；On the other hand, the utility model can read pressure and piston by digital display manometer and displacement monitors
Change in displacement, improve the precision of monitoring.
Brief description of the drawings
The utility model is described further below in conjunction with the accompanying drawings：
Fig. 1 is structural representation of the present utility model.

D, gas solubility determines, and be zeroed displacement monitors 9, and opens the 3rd valve 11 and the second valve 10 successively, sees
The movement of push rod in piston container is examined, after push rod movement is stable, the record value of displacement monitors 9 is L1, pressure value P2。
E, the amount solubility s of substance for calculation：
In formula：PaRepresent standard atmospheric pressure 1.013 × 105Pa；P1、P2It is negative value to represent relatively large air pressure；R represents preferable
Gas constant 8.314J/molk；T represents absolute temperature, T=Celsius temperatures+273.15；V1Represent the volume of balance cylinder 1；
Unit：K, normal temperature state takes T=20+273.15=293.15k in the utility model；M represents gas molar quality,
Unit：g/mol.
