[0038] In this embodiment, the circulation chamber 15 can serve as a mixing space for carbon dioxide gas and other gases. In some preferred embodiments, the circulation chamber 15 can also be equipped with a pressure control unit 2 (not shown in the figure, but installed inside the circulation chamber). The pressure control unit 2 is used to adjust the pressure inside the circulation chamber 15. The pressure control unit 2 here is the same as the pressure control unit 2 inside the reactor 1. In this embodiment, the gas circulation is achieved through the circulation drive 18 to ensure that the gas is fully dissolved in the liquid.

[0039] The first circulation pipe 16 can be directly or indirectly connected to the bottom of the reactor 1.

The specific connection method can be wired or wireless.

[0048] The working principle of the carbon dioxide solubility testing equipment in this embodiment is as follows:

[0049] Water flows from water tank 11 into mineralization adjustment unit 12, then into temperature control unit 13 to adjust the water temperature, and finally the liquid enters reactor 1; carbon dioxide first enters circulation chamber 15, then enters circulation flow rate control unit 14 through circulation drive 18, and then enters water to dissolve. In order to ensure complete dissolution, carbon dioxide will continuously repeat this step through circulation chamber 15 and circulation drive 18. If it is necessary to investigate the effect of other gases on carbon dioxide dissolution, the gas in the first gas container 3 is started and introduced into transfer chamber 21, and finally enters reactor 1 to mix with other substances.

[0050] Finally, the carbon dioxide solubility calculation mainly uses water level data and density data to calculate the mass of the liquid before and after the gas is introduced. According to the law of conservation of mass, the increase in the mass of the liquid is the mass of carbon dioxide dissolved.

[0051] The solubility testing device in this embodiment can detect the solubility of carbon dioxide under different atmospheres and physical environments (temperature, pressure, flow rate, mineralization). Compared with the existing technology, it has a richer and more comprehensive detection environment setting, which enables a more comprehensive study of the solubility characteristics of carbon dioxide, provides more effective technical means for related research, and can produce beneficial effects in carbon dioxide capture and collection.

The water tank 11, mineralization regulating unit 12, temperature control unit 13, and micro / nano bubble generator 24 are connected sequentially via pipes. The outlet end of the micro / nano bubble generator 24 is connected to the reaction vessel 1. One end of the first circulation pipe 16 is connected to the micro / nano bubble generator 24.
