Description

Technical Field

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

[0002] An electrolytic cell is a device that uses an electric field applied between the anode and cathode to drive redox reactions in a solution, thereby achieving the preparation, separation, or energy conversion of substances. Existing electrolytic cells are typically composed of a single electrolysis unit or multiple electrolysis units stacked together.

[0003] Multi-layer stacked electrolytic cell structures require each pair of electrodes to be individually connected to a power source, resulting in complex internal wiring and a large space occupation. Furthermore, the number of units in a typical electrolytic cell is fixed after fabrication, making it impossible to flexibly adjust according to production needs. Moreover, if a unit or electrode fails, the entire electrolytic cell usually needs to be disassembled, leading to high maintenance costs, long downtime, and disruption to production continuity.

[0022] Figure 2 This is a schematic diagram of the structure of an electrode module according to an embodiment of this application. Detailed Implementation

[0023] 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.

[0024] like Figure 1 As shown, its structure includes an electrolysis device according to an embodiment of this application. Specifically, it includes a plurality of electrode modules 2, which are stacked sequentially along one direction.

[0025] The electrode module 2 includes an electrode sheet 4, which has an electrical connection terminal 41.

[0026] The adjacent electrode modules 2 are electrically connected to the positive or negative terminal of an external power source, and the electrical connection terminals 41 of the adjacent electrode modules 2 are staggered in the stacking direction.

[0027] In this application, the core structure of the electrolysis device consists of several identical electrode modules 2 stacked together. Each electrode module 2 includes an electrode sheet 4, which is provided with an electrical connection terminal 41 for electrical connection. When stacking the electrode modules 2, the electrical connection terminals 41 of adjacent electrode modules 2 are staggered, and the electrical connection terminals 41 of adjacent electrode modules 2 are respectively connected to the positive and negative terminals of an external power supply. For example, the electrode sheet of electrode module ① is electrically connected to the positive terminal of the external power supply, the electrode sheet of electrode module ② adjacent to electrode module ① is electrically connected to the negative terminal of the external power supply, the electrode module ③ adjacent to electrode module ② is electrically connected to the positive terminal of the external power supply, and so on, thereby forming a stacked arrangement with alternating polarities. These electrode modules are completely identical, and the electrical connection terminals of the electrode sheets of adjacent electrode modules are staggered (for example, the electrical connection terminals of electrode module ① and electrode module ② are staggered).

[0028] The beneficial effects of this application are as follows:

[0029] Using standardized electrode modules allows for the stacking or reduction of the number of modules according to actual needs, facilitating batch assembly. The uniform structure of the stacked electrode modules also promotes large-scale production and reduces costs. If a part of the electrolysis unit suffers localized damage, the corresponding individual electrode module can be replaced, reducing the construction and maintenance costs of the electrolysis components and extending their service life.

[0030] Standardized electrode modules are easy to assemble, and the circuit traces of the two poles are separated during the stacking process, avoiding complex internal wiring and improving reliability.

[0031] Regarding the electrolytic structure, preferably, the electrical connection terminals 41 of two electrode modules 2 spaced apart by one overlap in the stacking direction, facilitating the series connection of the synchronous circuit during the stacking of the electrode modules 2. For example, the electrical connection terminal of electrode module ① is located at the upper end of the projection direction, the electrical connection terminal of electrode module ② is located at the lower end of the projection direction, the electrical connection terminal of electrode module ③ is located at the upper end of the projection direction, the electrical connection terminal of electrode module ④ is located at the lower end of the projection direction, and so on. For example, electrode modules ① and ③ are connected to the positive terminal of the power supply, and electrode modules ② and ④ are connected to the negative terminal of the power supply. In this embodiment, these connections are not described in detail.

[0032] More preferably, for example, the electrical connection terminals 41 of adjacent electrode modules 2 are oriented in opposite directions in the stacking direction. For example, the electrical connection terminal of electrode module ① is located at the upper end in the projection direction, and the electrical connection terminal of electrode module ② is located at the lower end in the projection direction. Or, the electrical connection terminal of electrode module ① is located at the left end in the projection direction, and the electrical connection terminal of electrode module ② is located at the right end in the projection direction. In this embodiment, they will not be described in detail.

[0033] Regarding the electrical connection structure, in one embodiment, the electrolysis device further includes a first electrical connector 6 and a second electrical connector 7. Two adjacent electrode modules 2 are respectively connected to the first electrical connector 6 or the second electrical connector 7. That is, for example, the electrical connection end of electrode module ① is connected to the first electrical connector 6, the electrical connection end of electrode module ② is connected to the second electrical connector 7, the electrical connection end of electrode module ③ is connected to the first electrical connector 6, the electrical connection end of electrode module ④ is connected to the second electrical connector 7, and so on. Furthermore, the first electrical connector 6 and the second electrical connector 7 are electrically connected to the positive and negative terminals of an external power source, respectively, thereby supplying power to the electrode plates 4 of each electrode module 2.

[0034] The aforementioned electrical connection terminal 41 may be, for example, an electrical connection terminal 41 extending from the electrode plate 4 itself and connected to the first electrical connector 6 or the second electrical connector 7; or, for example, an electrical connection terminal 41 for mounting a conductive element 42, the conductive element 42 being connected to the first electrical connector 6 or the second electrical connector 7. In this embodiment, these will not be described in detail.

[0035] Regarding the electrode device structure, in one embodiment, the electrode module 2 further includes a mounting base 3 having a mounting surface 31 on which the electrode sheet 4 is mounted. The mounting base 3 provides a frame for mounting and fixing the electrode sheet 4. By mounting the electrode sheet 4 onto the mounting base 3 and stacking the mounting bases 3 sequentially, the electrode sheet 4 is arranged in a sequentially stacked manner.

[0036] Regarding the electrode device structure, in a preferred embodiment, the mounting base 3 has two opposing mounting surfaces 31, meaning that the mounting base 3 can mount two opposing electrode plates 4. Furthermore, the electrode plates 4 of the same mounting base 3 are electrically connected to the same pole of an external power source; that is, all electrodes mounted on the same mounting base 3 have the same polarity (both are anodes or both are cathodes). It should be understood that the mounting base 3 of the electrode module 2 may optionally mount one or two electrode plates 4. For example, electrode module ① has one electrode plate connected to the positive pole of the power source (i.e., the anode), electrode module ② has two electrode plates connected to the negative pole of the power source (i.e., the cathode), and electrode module ③ has one electrode plate connected to the positive pole of the power source (i.e., the anode). In this embodiment, two sets of unit slots are formed, and so on. By stacking and combining electrode modules with the same structure to form an electrolysis device, assembly is simple, facilitating the arrangement of multi-layer stacked circuit connection structures.

[0037] Regarding the electrode device structure, in one embodiment, the electrolysis device further includes an end cap 30, which is mounted on the outer side of the outermost electrode module 2. That is, the end cap 30 is mounted at both ends of the assembly composed of multiple electrode modules 2. Furthermore, the end cap 30 has a mounting surface 31 facing the electrode module 2, and electrode plates 4 are mounted on the mounting surface 31. The electrode plates 4 are connected to the positive or negative terminal of an external power supply, and their polarity is opposite to that of the adjacent electrode module 2. In this embodiment, the end cap and the electrode modules 2 together constitute an electrolysis assembly formed by multiple sets of unit cells. The structure is simple, easy to assemble, and facilitates the arrangement of multi-layer stacked circuit connection structures.

[0038] Regarding the structure of the electrolysis device, in one embodiment, the electrode module 2 further includes an electrolyte membrane 5, which is mounted on the surface of the electrode sheet 4. When the electrode modules 2 are stacked, the electrolyte membrane 5 is sandwiched between the electrode sheets 4 of the two electrode modules 2. In a preferred embodiment, the electrode module 2 has two mounting surfaces 31, on which the electrode sheets 4 are mounted, and the electrolyte membrane 5 is disposed on the surface of the electrode sheet 4 facing away from the mounting surfaces 31. When the electrode modules 2 are stacked, the electrolyte membrane 5 is sandwiched between the electrode sheets 4 of the two electrode modules 2. For example, the electrolyte membrane 5 is a proton exchange membrane (PEM), which functions to provide a hydrogen ion channel, i.e., the H generated at the anode. + The protons migrate through the proton exchange membrane 5 to the cathode, thereby increasing the reaction rate and the product formation rate.

[0039] Regarding the structure of the electrolysis device, in one embodiment, the electrolyte membrane 5 is a single sheet or multiple electrolyte membrane units spaced apart from each other. That is, the electrolyte membrane 5 is a single sheet membrane, or the electrolyte membrane 5 comprises multiple electrolyte membrane units spaced apart from each other. For example, the electrolyte membrane 5 comprises multiple spaced-apart strip-shaped electrolyte membrane units, or, as another example, the electrolyte membrane 5 comprises multiple spaced-apart dot-shaped electrolyte membrane units. This creates pathways 12 between the electrolyte membrane units, allowing water to flow and quickly remove products generated on the electrode surface.

[0040] Regarding the water flow path of the electrolysis device, in one embodiment, two adjacent electrode modules 2 are stacked to form a channel 11 for water flow. Water flows between the two electrode plates 4, is converted into electrolytic products, and carried away. For example, an electrolyte membrane 5 is disposed between the two electrode plates 4, and the electrolyte membrane 5 comprises multiple spaced electrolyte membrane 5 units. The electrolyte membrane improves electrolysis efficiency while forming a passage for water flow.

[0041] Regarding the structure of the electrolysis device, in one embodiment, the electrolysis device further includes a housing 1, the housing 1 forming an electrolysis chamber 10, each of the electrode modules 2 being installed in the electrolysis chamber 10, and the housing 1 having an inlet and an outlet communicating with the electrolysis chamber 10.

[0042] For example, the water flow at the inlet may be parallel to the direction of the electrode plate 4, or the water flow at the inlet may be perpendicular to the direction of the electrode plate 4. In this embodiment, these will not be described in detail.

[0043] In one embodiment, the material of the electrode sheet 4 includes one or more of conductive silicon, conductive diamond, or elements, alloys, or compounds of titanium, platinum, lead, tantalum, iridium, palladium, niobium, tungsten, molybdenum, and ruthenium.

[0044] The electrolysis device described in this application generates water containing oxidized groups through low-pressure electrolysis of water. This water is rich in oxidized groups, such as ozone, oxygen atoms, and hydroxyl radicals. It can effectively kill bacteria and viruses and can be widely used in household appliances, sanitary ware, and industrial fields.

[0045] 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.

[0046] 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.
