Technical Field

[0001] This utility model relates to the field of electrolytic cell technology, and in particular to an electrolysis device. Background Technology

[0002] The electrolytic cell is the core equipment in the electrolysis process. Based on the type of electrolyte, it can be divided into three categories: aqueous solution electrolytic cells, molten salt electrolytic cells, and non-aqueous solution electrolytic cells. When direct current passes through the electrolytic cell, an oxidation reaction occurs at the anode-solution interface, and a reduction reaction occurs at the cathode-solution interface, to produce the desired product.

[0003] An electrolytic cell generally includes pipes, electrodes, and an electrode frame located at the edge of the electrodes. The electrodes and the electrode frame together form an electrolytic chamber. The pipes are connected to the electrode frame and communicate with the electrolytic chamber. The pipes include an inlet pipe and an outlet pipe, both of which communicate with the electrolytic chamber. The electrolyte enters the electrolytic chamber through the inlet pipe, where an oxidation-reduction reaction occurs. The gas produced by electrolysis is discharged through the outlet pipe.

[0004] However, in the existing technology, the electrolyte in the electrolysis chamber is prone to leakage from the connection between the electrode frame and the pipeline, which affects equipment safety and pollutes the environment.

[0005] Therefore, this application provides a new electrolysis apparatus to address the above-mentioned problems. Utility Model Content

[0012] Furthermore, when the pipe is an inlet pipe, the second end is sealed, and the connecting pipe is provided with a through hole. After the connecting pipe is inserted into the through hole, it communicates with the electrolysis chamber through the through hole.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Example 1 Please see Figure 1 and Figure 2A This embodiment provides an electrolysis device, which includes a pipe 1, a first sealing ring 4, a locking mechanism, an electrode plate 6, and an electrode frame 7 disposed at the edge of the electrode plate 6. The electrode plate 6 and the electrode frame 7 together form an electrolysis chamber, and the electrode frame 7 is provided with a channel structure communicating with the electrolysis chamber. The first sealing ring 4 is disposed between the pipe 1 and the electrode frame 7, the pipe 1 is connected to the channel structure through the first sealing ring 4, and the locking mechanism can lock the electrode frame 7, the first sealing ring 4, and the pipe 1.

[0027] It should be noted that in the electrolysis device of this embodiment, the pipe 1 can be either the liquid inlet pipe 2 or the gas outlet pipe 3. When the pipe 1 is the liquid inlet pipe 2, the electrolyte can enter from the liquid inlet pipe 2 and enter the channel structure through the first sealing ring 4. Since the channel structure is connected to the electrolysis chamber, the electrolyte can enter the electrolysis chamber from the channel structure. When the pipe 1 is the gas outlet pipe 3, the gas generated by electrolysis in the electrolysis chamber can enter the gas outlet pipe 3 through the channel structure and the first sealing ring 4 in sequence and be discharged from the gas outlet pipe 3.

[0028] The first sealing ring 4 is placed between the pipe 1 and the electrode frame 7, and the first sealing ring 4 is locked between the electrode frame 7 and the pipe 1 by a locking mechanism. This arrangement enhances the sealing between the pipe 1 and the electrode frame 7 and reduces the risk of leakage of electrolyte and gas generated by electrolysis from the connection between the electrode frame 7 and the pipe 1.

[0029] In addition, it should be noted that the channel structure on the pole frame 7 can be either a through hole 71 or a connecting groove. The specific structural form is not limited in this embodiment, as long as it can achieve the connection between the electrolysis chamber, the first sealing ring 4 and the pipe 1.

[0030] Preferably, please refer to Figure 7 and Figure 8 and combined Figure 2A The pipe 1 bends outward on the side near the pole frame 7 to form a first fold 11, and the first sealing ring 4 is disposed between the first fold 11 and the pole frame 7.

[0031] With this configuration, the pipe 1 is connected to the first sealing ring 4 through the first fold 11. The first fold 11 increases the contact area between the pipe 1 and the first sealing ring 4, thereby increasing the pressure on the first sealing ring 4 and improving the sealing performance between the first sealing ring 4 and the pole frame 7 and the pipe 1.

[0032] Preferably, please refer to Figure 2A and Figure 5 In this embodiment, the locking mechanism includes a threaded connector (not shown in the figure), a gasket 51 and a sealing flange 52. The gasket 51 and the sealing flange 52 are both sleeved on the outside of the pipe 1. The threaded connector passes through the sealing flange 52, the gasket 51, the first folded edge 11 and the first sealing ring 4 in sequence and is then screwed onto the pole frame 7.

[0033] Optionally, the threaded connector is a bolt, screw, stud, or threaded rod, etc., which has external threads and can be tightened into a threaded hole structure.

[0034] It should be noted that, please refer to [link / reference needed]. Figure 10 The sealing flange 52, gasket 51, first folded edge 11 and first sealing ring 4 are all provided with connection holes 41, and the pole frame 7 is provided with screw holes. Therefore, the threaded connector can pass through the connection holes 41 on the sealing flange 52, gasket 51, first folded edge 11 and first sealing ring 4 in sequence and then be screwed into the screw holes on the pole frame 7, thereby fastening the sealing flange 52, gasket 51, first folded edge 11 and first sealing ring 4 to the pole frame 7, that is, locking the pipe 1, the first sealing ring 4 and the pole frame 7.

[0035] This configuration locks the first sealing ring 4 between the pole frame 7 and the pipe 1, thereby sealing the connection between the pole frame 7 and the pipe 1 and preventing leakage.

[0036] Optionally, in this embodiment, the sealing flange 52 and the first sealing ring 4 can have the same structure, both having a connection hole 41 and a liquid passage hole 42 for the electrolyte to flow through. It should be noted that the shape of the sealing flange 52 and the first sealing ring 4 is not limited here; they can be... Figure 10 The oblong structure shown, or is Figure 11 The rectangular structure shown, or is Figure 12 The elliptical structure shown, or is Figure 13 The square structure is shown. Furthermore, the number of connecting holes 41 is not limited here; the number of connecting holes 41 can be two or four, etc.

[0037] Preferably, in this embodiment, pipe 1 is a non-metallic pipe, that is, both the liquid inlet pipe 2 and the air outlet pipe 3 are non-metallic pipes, for example, both the liquid inlet pipe 2 and the air outlet pipe 3 are plastic pipes.

[0038] It should be noted that in the existing technology, the inlet pipe and outlet pipe of the electrolytic cell are both metal pipes. Since the inlet pipe is used to transport alkaline solution, and the gas generated by electrolysis inevitably contains a small amount of alkaline solution, as the entire electrolysis operation time is extended, the alkaline solution can easily corrode the metal pipe. The corroded metal pipe is prone to metal debris falling off. Once the fallen metal debris blocks the inlet pipe and outlet pipe, it will cause the inlet and outlet of the liquid and gas to be obstructed. In severe cases, it will greatly increase the hydrogen (HTO) content in the oxygen, leading to serious safety hazards.

[0039] In this embodiment, both the liquid inlet pipe 2 and the gas outlet pipe 3 are non-metallic pipes. Since they do not contain metallic materials, stray current can be greatly reduced and the service life of the electrolytic cell can be extended.

[0040] It should be noted that electrolytic cells include unipolar and bipolar types. In a unipolar electrolytic cell, the electrolytic chambers on both sides of electrode 6 have the same polarity, while in a bipolar electrolytic cell, the electrolytic chambers on both sides of electrode 6 have different polarities. Please refer to [link to relevant documentation]. Figure 1 In this embodiment, taking a bipolar electrolytic cell as an example, the electrolysis chambers on the front and back sides of the electrode plate 6 are the anode chamber and the cathode chamber, respectively. The pipe 1 includes an inlet pipe 2 and an outlet pipe 3. Both the inlet pipe 2 and the outlet pipe 3 are provided in two sets. One set of inlet pipe 2 and outlet pipe 3 is the anode inlet pipe 2 and anode outlet pipe 3, which are both connected to the anode chamber. The other set of inlet pipe 2 and outlet pipe 3 is the cathode inlet pipe 2 and cathode outlet pipe 3, which are both connected to the cathode chamber.

[0041] Please see Figure 1 For the same electrolysis chamber, to improve the uniformity of the electrolyte and the smoothness of gas flow, the inlet pipe 2 and the outlet pipe 3 are usually arranged diagonally. That is, in the cathode chamber, the inlet pipe 2 is located in the lower right corner, and the outlet pipe 3 is located in the upper left corner; in the anode chamber, the inlet pipe 2 is located in the lower left corner, and the outlet pipe 3 is located in the upper right corner. The pipes 1 in the cathode chamber and the anode chamber are structurally identical and arranged symmetrically.

[0042] Example 2 Please see Figure 1 This embodiment provides an electrolysis device. In the electrolysis device, the pipe 1 includes an inlet pipe 2 and an outlet pipe 3. It should be noted that the electrolyte can enter the electrolysis chamber through the inlet pipe 2. After the electrolysis reaction occurs in the electrolysis chamber, the generated gas can be discharged through the outlet pipe 3.

[0043] Optionally, a first sealing ring 4 is provided between the liquid inlet pipe 2 and the electrode frame 7, the liquid inlet pipe 2 is connected to the channel structure through the first sealing ring 4, and the locking mechanism can lock the electrode frame 7, the first sealing ring 4 and the liquid inlet pipe 2; or, a first sealing ring 4 is provided between the air outlet pipe 3 and the electrode frame 7, the air outlet pipe 3 is connected to the channel structure through the first sealing ring 4, and the locking mechanism can lock the electrode frame 7, the first sealing ring 4 and the air outlet pipe 3.

[0044] Preferably, in this embodiment, please refer to Figure 2A A first sealing ring 4 is provided between the inlet pipe 2 and the electrode frame 7. The inlet pipe 2 is connected to the channel structure through the first sealing ring 4, and the locking mechanism can lock the electrode frame 7, the first sealing ring 4, and the inlet pipe 2; please refer to Figure 4 A first sealing ring 4 is provided between the air outlet pipe 3 and the pole frame 7. The air outlet pipe 3 is connected to the channel structure through the first sealing ring 4, and the locking mechanism can lock the pole frame 7, the first sealing ring 4 and the air outlet pipe 3.

[0045] This configuration ensures good sealing between the inlet pipe 2 and the outlet pipe 3 and the electrode frame 7, reducing the risk of leakage of electrolyte and gas generated during electrolysis from the connection between the electrode frame 7 and the pipe 1.

[0046] As the first feasible method, please refer to Figure 4 The channel structure is a through hole 71, and the pipe 1 is connected to the through hole 71 through the liquid passage hole 42 on the first sealing ring 4.

[0047] With this configuration, when pipe 1 is the inlet pipe 2, the electrolyte can enter the inlet pipe 2, pass through the liquid passage hole 42 of the first sealing ring 4, and enter the through hole 71, and then enter the electrolysis chamber for electrolysis reaction; when pipe 1 is the outlet pipe 3, the gas formed in the electrolysis chamber can enter the through hole 71, pass through the liquid passage hole 42 of the first sealing ring 4, and then enter the outlet pipe 3, and be discharged from the outlet pipe 3.

[0048] As a second possible approach, please refer to Figure 2A The electrolysis device also includes a connecting pipe 8, the channel structure being a through hole 71, the connecting pipe 8 being inserted into the through hole 71, and the connecting pipe 8 communicating with the electrolysis chamber; the connecting pipe 8 includes a first end and a second end arranged opposite to each other, the end of the connecting pipe 8 closer to the pipe 1 being the first end, the first end protruding from the electrode frame 7 and inserted into the liquid passage hole 42 of the first sealing ring 4; wherein, the first end is connected to the pipe 1 through the liquid passage hole 42, or the first end is directly connected to the pipe 1 through the liquid passage hole 42.

[0049] Optionally, the connecting pipe 8 is inserted into the through hole 71 and is locked and snapped into the support structure inside the electrolysis chamber. Alternatively, it can be fixedly installed to the electrode frame 7 by means of screws or clamps. The support structure inside the electrolysis chamber can be a hole structure or a groove structure.

[0050] For example, when the connecting pipe 8 is inserted into the liquid passage hole 42 of the first sealing ring 4, and the first end is located inside the liquid passage hole 42, the first end of the connecting pipe 8 is connected to the pipe 1 through the liquid passage hole 42. Therefore, please refer to... Figure 2AWhen pipe 1 is the inlet pipe 2, the electrolyte enters through the inlet pipe 2, passes through the liquid passage hole 42 on the first sealing ring 4, and then enters the connecting pipe 8 from the first end, and finally enters the electrolysis chamber through the connecting pipe 8; please refer to Figure 2B When pipe 1 is the gas outlet pipe 3, the gas in the electrolysis chamber can enter the connecting pipe 8 from the second end, pass through the liquid passage hole 42 on the first sealing ring 4, and then enter the gas outlet pipe 3 and be discharged from the gas outlet pipe 3.

[0051] Alternatively, when the connecting pipe 8 is inserted into the liquid passage hole 42 of the first sealing ring 4, and the first end of the connecting pipe 8 is flush with the side of the liquid passage hole 42 near the liquid inlet pipe 2, or when the first end of the connecting pipe 8 passes through the liquid passage hole 42 and protrudes from the liquid passage hole 42, the connecting pipe 8 is directly connected to the pipe 1. Therefore, when the pipe 1 is the liquid inlet pipe 2, the electrolyte directly enters the connecting pipe 8 through the liquid inlet pipe 2 and then enters the electrolysis chamber through the connecting pipe 8; when the pipe 1 is the gas outlet pipe 3, the gas in the electrolysis chamber can enter the connecting pipe 8 from the second end and directly enter the gas outlet pipe 3 through the connecting pipe 8, and then be discharged through the gas outlet pipe 3.

[0052] The first end of the connecting pipe 8 protrudes from the pole frame 7 and is inserted into the liquid passage hole 42 of the first sealing ring 4. With this arrangement, the first sealing ring 4 is in contact with the pole frame 7 on one hand and with the part of the connecting pipe 8 protruding from the pole frame 7 on the other hand, which can form two contact sealing surfaces, thereby strengthening the sealing strength and further preventing electrolyte or gas leakage.

[0053] Preferably, in this embodiment, the connecting pipe 8 is a non-metallic pipe, for example, a plastic pipe. This design, since the connecting pipe 8 does not contain metallic materials, can further reduce stray current and extend the service life of the electrolytic cell.

[0054] Example 3 In this embodiment, pipe 1 is used as the inlet pipe 2 for illustration.

[0055] Please see below. Figure 2A The electrolysis device also includes a connecting pipe 8, the channel structure of which is a through hole 71. The connecting pipe 8 is inserted into the through hole 71 and is connected to the electrolysis chamber. The connecting pipe 8 includes a first end and a second end that are arranged opposite to each other. The first end protrudes out of the electrode frame 7 and is inserted into the liquid passage hole 42 of the first sealing ring 4. The first end is connected to the liquid inlet pipe 2 through the liquid passage hole 42, or the first end is directly connected to the liquid inlet pipe 2 through the liquid passage hole 42.

[0056] With this configuration, the electrolyte enters through the inlet pipe 2, passes through the liquid passage hole 42 on the first sealing ring 4, and then enters the connecting pipe 8, and finally enters the electrolysis chamber through the connecting pipe 8; or, the electrolyte directly enters the connecting pipe 8 through the inlet pipe 2, and then enters the electrolysis chamber through the connecting pipe 8.

[0057] Preferably, please refer to Figure 9 In this embodiment, the second end is sealed, and the connecting pipe 8 is provided with a connecting hole 81. After the connecting pipe 8 is inserted into the through hole 71, it communicates with the electrolysis chamber through the connecting hole 81. Multiple connecting holes 81 are provided, and the multiple connecting holes 81 are spaced apart along the axial direction of the connecting pipe 8.

[0058] The second end of the connecting pipe 8 is sealed. For example, a sealing baffle is fixedly connected to the second end of the connecting pipe 8, or the sealing baffle at the second end of the connecting pipe 8 is integrally formed with the connecting pipe 8.

[0059] This configuration allows the connecting pipe 8 to be connected to the electrolysis chamber via the connecting holes 81. The connecting pipe 8 has multiple connecting holes 81, which improves the efficiency of electrolyte entering the electrolysis chamber.

[0060] Optionally, the multiple connecting holes 81 are evenly distributed along the axial direction of the connecting pipe 8, or the distribution density of the multiple connecting holes 81 gradually decreases along the flow direction of the fluid in the connecting pipe 8.

[0061] Preferably, please refer to Figure 9 and Figure 14 The first end of the connecting pipe 8 is bent outward to form a second fold 82, and a second sealing ring 9 is provided between the second fold 82 and the pole frame 7.

[0062] The second fold 82 provides a certain degree of sealing between the connecting pipe 8 and the electrode frame 7, preventing electrolyte in the electrolysis chamber from leaking out through this gap. The second sealing ring 9 further enhances the sealing performance between the connecting pipe 8 and the electrode frame 7.

[0063] Preferably, please refer to Figure 5 A positioning boss 83 is provided at the end of the connecting pipe 8 away from the second fold 82. The positioning boss 83 plays a positioning role to prevent the connecting pipe 8 from being rotated during installation, which would cause the position of the connecting hole 81 at the top of the connecting pipe 8 to shift.

[0064] Optionally, please refer to Figure 5 Along the axis perpendicular to the connecting pipe 8, the cross-section of the positioning boss 83 is polygonal, such as triangular, quadrilateral, pentagonal, etc. The non-cylindrical structure of the positioning boss 83 makes it easier for technicians to observe the installation direction of the connecting pipe 8.

[0065] Preferably, please refer to Figure 3 and Figure 6 A sealing groove is provided on the pole frame 7 near the second folded edge 82, and the second sealing ring 9 and the second folded edge 82 are both provided in the sealing groove.

[0066] The sealing groove is designed so that the second sealing ring 9 and the second folded edge 82 are both located within the pole frame 7. After the second sealing ring 9 is located within the sealing groove, the pole frame 7, the second sealing ring 9, and the second folded edge 82 are locked together under the squeezing action of the second folded edge 82. The second sealing ring 9 is in contact with the pole frame 7 on one side, with the outer peripheral wall of the connecting pipe 8 on the other side, and with the second folded edge 82 on the third side. This increases the number of contact sealing surfaces, further enhancing the sealing strength and preventing electrolyte leakage.

[0067] Example 4 In this embodiment, pipe 1 is used as the air outlet pipe 3 as an example for explanation.

[0068] Please see below. Figure 2B As a first feasible method, the electrolysis device also includes a connecting pipe 8, the channel structure being a through hole 71, the connecting pipe 8 being inserted into the through hole 71 and communicating with the electrolysis chamber; the connecting pipe 8 includes a first end and a second end arranged opposite to each other, the first end protruding from the electrode frame 7 and being inserted into the liquid passage hole 42 of the first sealing ring 4; wherein, the first end is connected to the pipe 1 through the liquid passage hole 42, or the first end is directly connected to the pipe 1 through the liquid passage hole 42.

[0069] The connecting pipe 8 is inserted into the through hole 71 and then connected to the electrolysis chamber through its second end.

[0070] With this configuration, the gas in the electrolysis chamber can enter the connecting pipe 8 from the second end, pass through the liquid passage hole 42 on the first sealing ring 4, and then enter the gas outlet pipe 3 and be discharged from the gas outlet pipe 3. Alternatively, the gas in the electrolysis chamber can enter the connecting pipe 8 from the second end and directly enter the gas outlet pipe 3 through the connecting pipe 8 and be discharged from the gas outlet pipe 3.

[0071] The first end of the connecting pipe 8 protrudes from the pole frame 7 and is inserted into the liquid passage hole 42 of the first sealing ring 4. With this arrangement, the first sealing ring 4 is in contact with the pole frame 7 on one hand and with the part of the connecting pipe 8 protruding from the pole frame 7 on the other hand, which can form two contact sealing surfaces, thereby strengthening the sealing strength and preventing gas leakage.

[0072] As a second possible approach, please refer to Figure 4 The channel structure is a through hole 71, and the air outlet pipe 3 is connected to the through hole 71 through the liquid passage hole 42 on the first sealing ring 4.

[0073] With this configuration, the gas generated in the electrolysis chamber can enter the through hole 71, pass through the liquid passage hole 42 of the first sealing ring 4, and enter the gas outlet pipe 3, and be discharged from the gas outlet pipe 3.

[0074] The first sealing ring 4 enhances the sealing between the gas outlet pipe 3 and the electrode frame 7, reducing the risk of gas generated by electrolysis leaking from the connection between the electrode frame 7 and the gas outlet pipe 3.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
