Description

Technical Field

[0001] The utility model relates to the field of electrolytic hydrogen production, in particular to a gas-liquid separation device. Background Art

[0002] The important links in water electrolysis hydrogen production include power supply, electrolytic cell, separation, washing and cooling equipment and electrolyte. The electrolyte is very important here. It directly affects the efficiency of electrolysis and the quality of hydrogen produced. If there is a problem with the quality of the electrolyte, no matter how good the production equipment is, it will not be able to produce hydrogen normally and output qualified hydrogen. Selecting qualified electrolytes (such as potassium hydroxide, sodium oxide) as required and ensuring the purity of the water used are the first step to ensure the quality of the electrolyte. Otherwise, the quality of the electrolyte cannot be guaranteed.

[0003] However, since certain impurity gases may remain in the hydrogen produced by electrolysis, the purity of the hydrogen will be affected when it is directly collected. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a gas-liquid separation device to solve the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions: a gas-liquid separation device, comprising an electrolytic cell and an upper cover, wherein a hydrogen discharge structure is installed on one side of the upper surface of the upper cover, and an oxygen discharge structure is installed on the other side of the upper surface of the upper cover, the hydrogen discharge structure comprising: an outer sleeve, a conical through hole, an outer conical sleeve is arranged above the conical through hole, a connecting rod is connected between the outer conical sleeve and the conical through hole, an inner converging plate is installed on the inner side wall of the outer sleeve above the outer conical sleeve, an exhaust pipe is arranged above the inner converging plate, and a flexible sleeve is installed on one end of the exhaust pipe located close to the inner converging plate.

[0006] As a further solution of the present invention: a power supply is installed on the upper surface of the upper cover between the hydrogen exhaust structure and the oxygen exhaust structure, a cathode electrolysis wire is installed through the upper cover on the side of the power supply close to the oxygen exhaust structure, and an anode electrolysis wire is installed through the upper cover on the side of the power supply close to the hydrogen exhaust structure.

[0007] As a further solution of the present invention: a diaphragm is installed on the lower surface of the upper cover between the cathode electrolysis wire and the anode electrolysis wire.

[0008] As a further solution of the present invention: the tapered through hole is connected to the upper cover, and the outer tapered sleeve is fixedly connected to the tapered through hole via the connecting rod.

[0009] As a further solution of the present invention: the diaphragm is fixedly connected to the upper cover.

[0010] As a further solution of the present invention: the cathode electrolysis wire and the anode electrolysis wire are both electrically connected to the power supply.

[0011] As a further solution of the present invention: the outer sleeve is a transparent material component, and the outer sleeve and the upper cover are fixedly formed as one piece.

[0012] As a further solution of the present invention: a pipe clamp is installed at the connection between the outer side of the flexible sleeve and the inner converging plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. Use a pipe to insert from the inside of the inner converging plate to the bottom position of the outer sleeve and then inject the impurity removal solution so that the overall liquid level is lower than the upper end surface of the tapered through-hole. The hydrogen carrying any remaining impurities will pass through the outer sleeve as a whole. Under the blockage of the outer conical sleeve, the hydrogen will be adsorbed from the alkaline solution inside the outer sleeve to remove impurities. The hydrogen will then continue to move upward to ensure the purity of the collected hydrogen. BRIEF DESCRIPTION OF THE DRAWINGS

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] like Figure 1-5 As shown, this embodiment provides a gas-liquid separation device, including an electrolytic cell 1 and an upper cover 2, a hydrogen discharge structure 3 is installed on one side of the upper surface of the upper cover 2, and an oxygen discharge structure 4 is installed on the other side of the upper surface of the upper cover 2, the hydrogen discharge structure 3 includes: an outer sleeve 301, a tapered through hole 302, the outer sleeve 301 is a transparent material component, the outer sleeve 301 and the upper cover 2 are fixedly formed as a whole, the tapered through hole 302 is connected to the upper cover 2, an outer tapered sleeve 303 is provided above the tapered through hole 302, and an outer tapered sleeve 303 is provided above the tapered through hole 302. A connecting rod 304 is connected between the conical sleeve 303 and the conical through hole 302. The outer conical sleeve 303 is fixedly connected to the conical through hole 302 through the connecting rod 304. An inner converging plate 305 is installed above the outer conical sleeve 303 on the inner side wall of the outer sleeve 301. An exhaust pipe 306 is provided above the inner converging plate 305. A flexible sleeve 307 is installed at one end of the exhaust pipe 306 close to the inner converging plate 305. A pipe clamp is installed at the connection between the outer side of the flexible sleeve 307 and the inner converging plate 305.

[0023] like Figure 2-3 As shown, in this embodiment, a power supply 6 is installed on the upper surface of the upper cover 2 between the hydrogen exhaust structure 3 and the oxygen exhaust structure 4, a cathode electrolysis wire 601 is installed on the side of the power supply 6 close to the oxygen exhaust structure 4 and passes through the upper cover 2, and an anode electrolysis wire 602 is installed on the side of the power supply 6 close to the hydrogen exhaust structure 3 and passes through the upper cover 2, both the cathode electrolysis wire 601 and the anode electrolysis wire 602 are electrically connected to the power supply 6, and a diaphragm 5 is installed on the lower surface of the upper cover 2 between the cathode electrolysis wire 601 and the anode electrolysis wire 602, and the diaphragm 5 is fixedly connected to the upper cover 2.

[0024] The working principle of the present invention is as follows: when in use, after pouring the electrolyte into the interior of the electrolytic cell 1 as a whole, the upper cover 2 is sealed as a whole at the upper end position of the electrolytic cell 1, and different adsorption solutions are selected to be poured into the interior of the outer sleeve 301 according to the type of electrolyte. When the impurities in the hydrogen are acidic impurities, a high-concentration alkaline solution is injected from the interior of the inner convergence plate 305 to the bottom position of the outer sleeve 301, so that the liquid level is lower than the upper end surface of the tapered through hole 302. The flexible sleeve 307 at the lower end of the exhaust pipe 306 is completely covered on the upper end of the inner convergence plate 305 and then fastened with a clamp. 6 The cathode electrolysis wire 601 and the anode electrolysis wire 602 are powered respectively to energize the electrolyte inside the electrolytic cell 1. Hydrogen will be generated at the position of the cathode electrolysis wire 601, and oxygen will be generated at the position of the anode electrolysis wire 602. The hydrogen will be transmitted to the inside of the outer sleeve 301 through the tapered through hole 302. The hydrogen will pass through the outer sleeve 301 as a whole, carrying any remaining impurities. After the hydrogen is blocked by the outer conical sleeve 303, the hydrogen will be removed from the alkaline solution inside the outer sleeve 301 by adsorption. After that, the hydrogen will continue to move upward, and under the interception effect of the inner converging plate 305, the hydrogen will be transferred and collected from the position of the exhaust pipe 306.
