[0018] Figure 1 This is a schematic diagram of the structure of a modular combined electrolytic cell according to an embodiment of this application. Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0020] like Figure 1 As shown, its structure includes a modular combined electrolytic cell according to an embodiment of this application, specifically including an outer shell 2 and several combined shells 1;

[0021] An electrolysis unit 10 is provided on the combined shell 1. The combined shell 1 is connected to the outer shell 2 so that the electrolysis unit 10 is disposed inside the outer shell 2. Each of the combined shell 1 forms a first electrolysis cavity 3, and the outer shell 2 forms a second electrolysis cavity 4. The first electrolysis cavity 3 and the second electrolysis cavity 4 are separated from each other.

[0022] The beneficial effects of this embodiment are:

[0023] The modular combined electrolytic cell of this application uses the combined shell 1 as the structure constituting the first electrolytic chamber 3, and the outer shell 2 as the structure constituting the second electrolytic chamber 4. By installing the combined shell 1 onto the outer shell 2 and installing the electrolytic unit 10 on the combined shell 1, the overall structure of the electrolytic cell is formed. This allows for the separate design of the flow channel structure of the two electrodes, thereby eliminating the complex flow channel structure of existing electrode-separated electrolytic cells. It can be quickly stacked and installed as needed, realizing large-scale assembly and production, resulting in lower construction and maintenance costs and a longer service life for the electrolytic cell.

[0024] Regarding the electrolytic structure, in one embodiment, the electrolytic unit 10 includes a first electrode 11, a diaphragm 12, and a second electrode 13. The surface of the first electrode 11 is exposed to the first electrolytic cavity 3, and the surface of the second electrode 13 is exposed to the second electrolytic cavity 4. The diaphragm 12 is disposed between the first electrode 11 and the second electrode 13, separating the spaces on both sides. That is, the first electrode 11, the diaphragm 12, and the second electrode 13 are mounted on the combined shell 1, and the diaphragm 12 separates the spaces on both sides, so that the combined shell 1 forms an independent first electrolytic cavity 3. The combined shell 1 is mounted on the outer shell 2, so that the outer shell 2 forms an independent second cavity. The surface of the first electrode 11 is exposed to the first electrolytic cavity 3 for reaction, and the surface of the second electrode 13 is exposed to the second electrolytic cavity 4 for reaction. This enables large-scale assembly and production.

[0025] For ease of description, the water flow path passing through the first electrode 11 is referred to as the first water path, and the water flow path passing through the second electrode 13 is referred to as the second water path.

[0026] Regarding the flow channel structure, in one embodiment, the combined shell 1 has an inlet end 5 and an outlet end 6, which are connected to the first electrolysis chamber 3. This allows the combined shell 1 itself to form a complete water flow path for the first water path (i.e., water enters the first electrolysis chamber 3 through the inlet end 5, reacts in the first electrolysis chamber 3, and then flows out from the outlet end 6), while the outer shell 2 does not participate in the formation of the first flow path. This allows for a separate design of the flow channel structures for the first and second water paths (i.e., a separate design for the cathode and anode flow paths) to achieve modular production and assembly.

[0027] Regarding the electrolytic structure, in one embodiment, the outer shell 2 is detachably connected to the combined shell 1. This allows the combined shell 1 to be easily installed and removed from the outer shell 2 for maintenance or replacement.

[0028] Regarding the electrolytic structure, in one embodiment, the first electrode 11 and / or the second electrode 13 are connected to conductive terminals, or the first electrode 11 and / or the second electrode 13 extend to form conductive terminals, which are electrically connected to an external power source. That is, for example, the first electrode 11 and / or the second electrode 13 are connected to conductive terminals, such as conductive sheets, conductive pillars, or other conductive structures, with the conductive terminals extending out of the first electrolytic cavity 3 and connected to an external power source; or, for example, the first electrode 11 and / or the second electrode 13 themselves extend to form conductive terminal portions, which extend out of the first electrolytic cavity 3 and are connected to an external power source.

[0029] Based on the above embodiments, in one embodiment, the modular combined electrolytic cell further includes a first electrical connector, wherein the conductive terminal of the first electrode 11 of each of the combined shells 1 is connected to the first electrical connector, and the first electrical connector is electrically connected to an external power source. In this embodiment, the first electrical connector is connected to the conductive terminal of each first electrode 11, and the external power source supplies power to each first electrode 11 through the first electrical connector.

[0030] Based on the above embodiments, in one embodiment, the modular combined electrolytic cell further includes a second electrical connector, wherein the conductive terminal of the second electrode 13 of each of the combined shells 1 is connected to the second electrical connector, and the second electrical connector is electrically connected to an external power source. In this embodiment, the second electrical connector is connected to the conductive terminal of each second electrode 13, and the external power source supplies power to each second electrode 13 through the second electrical connector.

[0031] In the above embodiments, the circuit connection of the electrolysis unit 10 is independently installed in the combined shell 1 and separated from the outer shell 2, making the electrical connection structure simpler. In modular production and assembly, the circuit installation is more convenient and efficient when the combined shell 1 is assembled or disassembled onto the outer shell 2.

[0032] Regarding the electrolytic structure, in one embodiment, the combined shell 1 is provided with a plurality of electrolytic units 10. For example, the combined shell 1 may have one electrolytic unit 10, two electrolytic units 10, or four electrolytic units 10. In this embodiment, they will not be described in detail.

[0033] It should be understood that in order to achieve the installation and connection of the combined shell 1 and the outer shell 2, and to enable the combined shell 1 to form the first electrolytic cavity 3, the combined shell 1 is cylindrical. For example, the combined shell 1 is cylindrical, for example, the combined shell 1 is polygonal, or for example, the combined shell 1 is spherical. In this embodiment, they will not be described one by one.

[0034] In a preferred embodiment, the combined shell 1 is cylindrical and has a mounting surface. The diaphragm 12 is mounted on the mounting surface and separates the spaces on both sides of the diaphragm 12, so that the combined shell 1 forms an independent first cavity inside the diaphragm 12. For example, the combined shell 1 is cylindrical and has an annular mounting surface. The diaphragm 12 is disposed along the mounting surface, so that the diaphragm 12 separates the spaces on both sides, and the combined shell 1 forms an independent first cavity inside the diaphragm 12. As another example, the combined shell 1 is rectangular and has multiple mounting surfaces. Each mounting surface has a diaphragm 12 separating the spaces on both sides, so that the combined shell 1 forms an independent first cavity inside the diaphragm 12.

[0035] For example, a connecting port is formed on the mounting surface, and the diaphragm 12 is installed on the connecting port to separate the spaces on both sides. There can be multiple connecting ports, with one diaphragm 12 installed on each connecting port to separate the spaces on both sides, thus isolating the cavities on both sides.

[0036] Furthermore, in a preferred embodiment, the first electrode 11 and / or the second electrode 13 are planar electrodes or curved electrodes. For example, the combined shell 1 is cylindrical, and the first electrode 11 and / or the second electrode 13 are curved electrodes (such as arc-shaped or annular). Alternatively, the combined shell 1 is a multifaceted three-dimensional cylindrical shape, and the first electrode 11 and / or the second electrode 13 are planar electrodes. In this embodiment, these are not described in detail.

[0037] Regarding the structure of the electrolytic cell, in one embodiment, the outer shell 2 has several mounting ports 7, and the combined shell 1 is assembled with the outer shell 2 through the mounting ports 7. By assembling the combined shell 1 onto the outer shell 2 through the mounting ports 7, the modular combined electrolytic cell of this application is formed. Its cathode and anode cavities are separated, and the assembly is convenient and simple. The number of electrolytic units 10 can be easily adjusted according to production needs.

[0038] Regarding the structure of the electrolytic cell, for example, a sealing ring is provided between the combined shell 1 and the outer shell 2 to ensure the airtightness of the combined shell 1 when installed in the outer shell 2.

[0039] The structure of this application is applicable to various electrolytic cells for separating anode and cathode products. Under the premise of ensuring the reliability of anode and cathode product separation, the electrolytic cell structure is redesigned to achieve simple and efficient production and assembly, improve the efficiency of large-scale production, and reduce the cost of system maintenance.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
