Description

Technical Field

[0001] The invention relates to the technical field of hydrogen production by electrolysis of water, and in particular to an electrolysis device. Background Art

[0002] A water electrolyzer is an electrochemical device. When direct current passes through an electrolyte containing water molecules, the water molecules undergo an electrochemical reaction on the electrodes. The water molecules lose electrons on the anode (positive electrode) and are oxidized to oxygen (O2). At the same time, they gain electrons on the cathode (negative electrode) and are reduced to hydrogen (H2). The purity of the electrolyzed water gas is an important indicator of alkaline water electrolysis. The gas crossover during alkaline water electrolysis is mainly caused by two phenomena: the dissolution of gas in the electrolyte and the diffusion of gas through the diaphragm. The hydrogen content on the oxygen-producing side of the membrane anode must be monitored to ensure that hydrogen and oxygen do not mix excessively, causing a potential explosion hazard.

[0003] In the prior art, when monitoring the hydrogen content on the oxygen-producing side of the membrane anode, a separate monitoring instrument needs to be set up, but such a setting will increase the overall cost. Summary of the invention

[0026] In the prior art, the concentration of hydrogen in oxygen is mainly determined by post-detection separation. Adding a hydrogen-oxygen separator to the external system connected to the electrolysis device will increase its equipment and operating costs. The method of reducing the concentration of hydrogen in oxygen in the electrolysis device is mainly to optimize the separator, but the industrial application of this method needs to be verified.

[0027] like Figure 1 As shown, the electrolysis device of this embodiment includes: a frame 10, an anode structure 20, a cathode structure 30, a separator 40 and a gas stopper 50. The frame 10 includes a first end plate 11 and a second end plate 12. The first end plate 11 is provided with a first electrolyte inlet 111 and a first outlet 112, and the second end plate 12 is provided with a second outlet 121. The anode structure 20 is arranged in the frame 10, and the anode structure 20 is connected with the first electrolyte inlet 111 and the first outlet 112. The anode structure 20 includes an anode plate 21 and an anode electrode 22. The cathode structure 30 is arranged in the frame 10, and the cathode structure 30 is connected with the second outlet 121. The separator 40 is arranged between the anode structure 20 and the cathode structure 30 to allow the electrolyte to flow through. The gas stopper 50 is arranged between the anode electrode 22 and the anode plate 21, and the gas stopper 50 is used to stop the gas from flowing out of the first outlet 112 at the position where the cathode structure 30 is located.

[0028] Applying the technical solution of this embodiment, the electrolysis device includes a frame 10, an anode structure 20, a cathode structure 30, a separator 40 and a gas stopper 50. The frame 10 includes a first end plate 11, on which a first electrolyte inlet 111 and a first outlet 112 are provided. The frame 10 also includes a second end plate 12, on which a second outlet 121 and a second electrolyte inlet 122 are provided. The anode structure 20, the cathode structure 30, the separator 40 and the gas stopper 50 are all arranged in the frame 10. The anode structure 20 is connected to the first electrolyte inlet 111. The anode structure 20 is connected to the first outlet 112. The anode structure 20 includes an anode plate 21 and an anode electrode 22. The cathode structure 30 is connected to the second outlet 121. The separator 40 is arranged between the anode structure 20 and the cathode structure 30 to allow the electrolyte to flow through. The gas stopper 50 is arranged between the anode electrode 22 and the anode plate 21, and the gas stopper 50 is used to stop the hydrogen from flowing out through the first outlet 112 at the location of the cathode structure 30. Through the above arrangement, the anode electrolyte can enter the anode structure 20 through the first electrolyte inlet, and the cathode electrolyte can enter the cathode structure 30 through the second electrolyte inlet 122, so that the oxygen generated after the electrolysis of the anode electrolyte can flow out through the first outlet 112, and the hydrogen generated by the electrolysis of the cathode electrolyte can flow out through the second outlet 121. The gas stopper 50 can stop the hydrogen from flowing out through the first outlet 112 at the location of the cathode structure 30, thereby reducing the probability of hydrogen mixing into oxygen, avoiding the risk, and also avoiding the problem of increased cost caused by separately setting up an instrument for monitoring the hydrogen concentration in oxygen on the anode side and setting up a hydrogen-oxygen separator on the anode side. Therefore, the technical solution of this embodiment effectively solves the problem of increased cost caused by the need to separately set up a hydrogen-oxygen separator in the related art.

[0029] There is water in the electrolyte.

[0030] The electrolysis device of this embodiment is an alkaline water electrolysis device.

[0031] The separator 40 is a separator film.

[0032] like Figure 1 As shown, in this embodiment, the gas stopper 50 includes a stopper film. The stopper film can stop hydrogen and reduce the concentration of hydrogen in oxygen.

[0033] Providing a stopper membrane in the electrolysis device does not increase the cost of subsequent hydrogen-oxygen separator equipment and can also ensure the safety of the electrolysis device.

[0034] The stopper membrane only isolates smaller hydrogen molecules, does not affect the passage of oxygen and electrolyte, and has no effect on the performance of the entire battery stack itself.

[0035] like Figure 1As shown, in this embodiment, the blocking film includes a metal organic framework film. The metal organic framework film can not only conduct electricity, but also block hydrogen.

[0036] Metal-organic framework membranes have good electron transport performance on the anode plate because their metal ligands are conductive.

[0037] In other embodiments, the stopper membrane comprises an ultrafiltration membrane.

[0038] like Figure 1 As shown, in this embodiment, the anode structure 20 further includes a gasket 23, a mounting hole 231 is provided on the gasket 23, the anode electrode 22 is disposed in the mounting hole 231, and the separator 40 is disposed between the gasket 23 and the anode plate 21. The gasket 23 can support the anode electrode 22. The gasket can also seal the water vapor of the electrolysis device.

[0039] The anode structure includes multiple anode structures, and the multiple anode structures are arranged in close contact with each other. The gasket has an insulating property, which can prevent arcs from being generated between the multiple anode structures, causing safety accidents, and ensure the safe use of the electrolysis device.

[0040] The gasket has the characteristics of high temperature resistance, high pressure resistance and alkali corrosion resistance, and also has a certain compression resilience, which is conducive to long-term testing of the electrolytic device without leakage of electrolyte and leakage of oxygen and hydrogen.

[0041] A layer of crystalline molecular sieve membrane is added between the anode plate 21 and the gasket 23 for filtering. The crystalline molecular sieve membrane can selectively pass oxygen but not hydrogen, thereby achieving the purpose of reducing the hydrogen concentration in oxygen.

[0042] The crystalline molecular sieve membrane is a stopper membrane.

[0043] The cathode structure is similar to the anode structure.

[0044] like Figures 2 to 4 As shown, in this embodiment, the electrolysis device further includes a connecting pipe 60 disposed on the frame 10, and the connecting pipe 60 is connected to the first outlet 112. Hydrogen and electrolyte can flow into the connecting pipe through the first outlet 112.

[0045] like Figure 2 As shown, in this embodiment, the connecting tube 60 includes a tube body 61 and a folded plate 62 disposed on the inner wall of the tube body 61, the folded plate 62 has at least one bent portion, and a plurality of through holes are disposed on the folded plate 62. When the electrolyte flows through the bent portion, it can impact the bent portion, thereby facilitating the separation of oxygen and the electrolyte.

[0046] By setting up the connecting pipe, the electrolyte and oxygen can be initially separated by band stratification in the pipe body to avoid the dissolution of gas in the electrolyte.

[0047] A gas tail gas collection bag was connected to the connecting pipe to collect the tail gas for gas chromatography. When the metal organic framework membrane was used, the volume concentration of hydrogen in the oxygen on the anode side was 0.08%, which was less than the 2% safety standard of hydrogen concentration on the anode side of the electrolyzer in industrial production. When the ultrafiltration membrane was used, the volume concentration of hydrogen in the oxygen on the anode side was 0.24%. When the metal organic framework membrane was not used, the volume concentration of hydrogen in the oxygen on the anode side was 1.31%.

[0048] like Figure 2 As shown, in this embodiment, the tube body 61 has an inlet end and an outlet end, the inlet end is connected between the first outlet 112 and the outlet end, the connecting tube 60 also includes a guide plate 63 and a partition plate 64, the guide plate 63 is connected between the folding plate 62 and the inner wall of the tube body 61, the partition plate 64 is connected to the inner wall of the tube body 61, and a plurality of first air outlet holes 641 are arranged at intervals on the partition plate 64, and the distance between the partition plate 64 and the axis of the tube body 61 gradually decreases in the direction from the inlet end of the tube body 61 to the outlet end of the tube body 61. The guide plate 63 can guide the flow of the electrolyte and oxygen. Hydrogen can flow out through the plurality of first air outlet holes 641 on the partition plate 64.

[0049] like Figure 2 As shown, in this embodiment, the middle portion of the guide plate 63 is arranged to protrude toward the partition plate 64. In this way, the electrolyte can flow more quickly toward the outlet end of the tube body after flowing through the middle portion of the guide plate.

[0050] like Figure 2 and Figure 3 As shown, in this embodiment, the guide plate 63 divides the tube body 61 into a first flow space 611 and a second flow space 612, the partition plate 64 divides the second flow space 612 into a first flow subspace 6121 and a second flow subspace 6122, the guide plate 63 is provided with a plurality of second air outlet holes 631, the connecting pipe 60 further includes a plurality of air outlet pipes 65, the first ends of the plurality of air outlet pipes 65 are arranged at intervals on the guide plate 63, the first ends of the plurality of air outlet pipes 65 are arranged one-to-one with the second air outlet holes 631, the second ends of the plurality of air outlet pipes 65 are arranged at intervals on the partition plate 64, and the second ends of the plurality of air outlet pipes 65 are connected with a part of the plurality of first air outlet holes 641, so that the gas in the first flow space 611 flows into the second flow subspace 6122 through the air outlet pipe 65. Through the above arrangement, the oxygen in the second flow space can flow into the second flow subspace through the air outlet pipe, thereby facilitating the separation of oxygen and electrolyte. When the electrolyte flows through the outlet pipe, it can collide with the outer wall of the outlet pipe, thereby facilitating the separation of the electrolyte and oxygen. The second ends of the plurality of outlet pipes 65 are connected to part of the plurality of first outlet holes 641, so that the gas in the first flow subspace can flow into the second flow subspace through the first outlet holes.

[0051] like Figure 4 As shown, in this embodiment, a plurality of convex thorns are also provided on the guide plate 63. By providing a plurality of convex thorns, it is convenient for bubbles to be punctured when flowing through the convex thorns, so as to facilitate the separation of oxygen and electrolyte.

[0052] The electrolysis device further includes a bent plate 66 , which is disposed on the inner wall of the tube body 61 .

[0053] The guide plate 63 includes a first plate body 632 and a second plate body 633 , and an obtuse angle is formed between the first plate body 632 and the second plate body 633 . The second air outlet 631 is disposed on the second plate body. The burr is disposed on the first plate body 632 .

[0054] The middle portion of the guide plate 63 protrudes toward the partition plate 64 and is located at the junction of the first plate body 632 and the second plate body 633 .

[0055] An obtuse angle is formed between the first plate 632 and the second plate 633 .

[0056] The bent plate 66 is connected between the first plate body 632 and the second plate body 633 .

[0058] The bent plate 66 has a similar structure to the folded plate 62. The bent plate 66 and the folded plate 62 are arranged in parallel.

[0059] The first end of the first plate body 632 is connected between the fourth plate body 622 and the fifth plate body 623 , and the second end of the first plate body 632 is connected between the fourth plate body 622 and the fifth plate body 623 of the bent plate 66 .

[0060] The bent plate 66 , the folded plate 62 and the partition plate 64 are sequentially arranged from the inlet end to the outlet end of the tube body 61 .

[0061] An obtuse angle is formed between the third plate 621 and the fourth plate 622. The intersection of the third plate 621 and the fourth plate 622 protrudes toward the inlet end of the tube.

[0066] The partition plate 64 and the second plate body 633 are arranged in parallel.

[0067] Some of the plurality of ridges are first ridges, and the other are second ridges.

[0068] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0069] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0070] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
