[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 4 , the utility model provides the following technical solutions:

[0023] A gas-liquid separation liquid storage tank device includes a liquid storage tank body 1, a waste liquid discharge port 2 and an access circulation pump inlet 9. The access circulation pump inlet 9 and the waste liquid discharge port 2 are installed at the bottom of both sides of the liquid storage tank body 1. A gas-liquid mixing inlet 6 is opened on the top of the back of the liquid storage tank body 1, and a cover plate is provided on the top of the liquid storage tank body 1.

[0024] The quantitative solution is replenished from the electrolyte stock liquid replenishing port and enters the upper cavity of the gas-liquid separation liquid storage tank body 1 through the through hole. The solution accumulates to a certain height on the layered partition 3 and flows into the lower cavity of the liquid storage tank body 1 from the overflow hole 10. When the liquid level reaches the lower edge of the limit pipe cap 5, the liquid will play a sealing role and the gas will not enter the lower cavity. After the gas-liquid separation liquid storage tank body 1 is replenished, the ball valve B will be opened, and the pump A1 will extract the liquid from the bottom of the gas-liquid separation liquid storage tank body 1 and pump it into the electrolytic cell and the waste liquid recovery storage tank H. The regulating valve D is adjusted to control the liquid flow rate, and the flow meter C Record the liquid flow rate, pump A1 operates normally, start rectifier G, start electrolysis, and electrochemical reaction occurs inside the electrolytic cell, producing a large amount of mixed solution of auxiliary gas and electrolyte. The container material, circulating electrolyte capacity, and gas output are customized according to the circulating electrolyte and auxiliary products. The electrolysis in the closed electrolytic cell generates a pressure of ≤0.2MPa and a temperature of ≤75°C, which enters the upper layer of the liquid storage tank body 1 through the gas-liquid mixing inlet 6. During the normal electrolysis process, the liquid in the gas-liquid separation liquid storage tank body 1 can be replenished according to the liquid level height without affecting the normal electrolysis process.

[0025] Pump A2 extracts the liquid from the bottom of the gas-liquid separation storage tank body 1 and passes it through the 3P chiller F and the switch E to achieve heat exchange. The cooled liquid re-enters the interior of the storage tank body 1 through the electrolyte stock liquid replenishment port.

[0026] A layered partition 3 is installed inside the liquid storage tank body 1, and a limiting liquid return pipe 4 is installed on the layered partition 3. A limiting pipe cap 5 is installed on the limiting liquid return pipe 4. The limiting liquid return pipe 4 and the limiting pipe cap 5 cooperate with each other to separate gas and liquid. An overflow hole 10 is opened on the limiting liquid return pipe 4, and the limiting pipe cap 5 covers the overflow hole 10. The bottom of the limiting pipe cap 5 is lower than the bottom of the overflow hole 10. There is a gap between the limiting pipe cap 5 and the limiting liquid return pipe 4. The overflow holes 10 are opened at equal angles around the limiting liquid return pipe 4, and at least one overflow hole 10 is set.

[0027] Since the lower edge of the limiting pipe cap 5 is sealed by liquid, the gas will not enter the lower layer from the limiting liquid return pipe 4. The upper layer of auxiliary gas accumulates more and more over time. The tank body 1 of the gas-liquid separation liquid storage tank belongs to a sealed system. The upper layer of auxiliary gas will overflow from the exhaust hole on the cover when a certain pressure is formed. The auxiliary gas can be reused.

[0028] When the electrolysis of the electrolytic solution in the electrolytic cell is completed to the point where no more electrolysis is possible, forming waste liquid, the pump A1 is turned off, the rectifier G is stopped, the electrolysis is turned off, and the electrolytic waste liquid is discharged into the waste liquid recovery storage tank H.

[0029] A negative pressure tube 7 is installed on the layered partition 3. There is a gap between the top of the negative pressure tube 7 and the top of the liquid storage tank body 1. Installation and fixing holes 8 are opened on both sides of the liquid storage tank body 1.

[0030] When the pump is working, it extracts the electrolyte in the lower layer, so that the auxiliary gas above the liquid storage tank body 1 enters the lower cavity through the negative pressure pipe 7. The negative pressure pipe 7 prevents the lower cavity space from generating negative pressure.

[0031] There are exhaust holes and through holes on both sides of the cover plate. The exhaust holes and through holes pass through the top of the liquid storage tank body 1. The through holes are used to pass the electrolyte solution into the liquid storage tank body 1. A sealing plug is clamped inside the exhaust hole.

[0032] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
