[0002] Electrolysis modules can decompose harmful substances in wastewater or liquids, thereby reducing the corresponding indicators in the discharged wastewater and ensuring compliance with emission standards. The electrolysis module contains alternating positive and negative electrode plates. When energized, an electrolysis space is formed between the positive and negative electrode plates, thus decomposing the flowing wastewater. For example, publication CN214990851U provides a treatment device for electrolytically removing ammonia nitrogen from wastewater.
[0003] However, in existing electrolysis modules, the ends of the electrode plates are joined with the tank walls to form a liquid flow channel, resulting in a cantilever structure for the electrode plates.

Furthermore, the electrode plates need to be assembled alternately as disclosed in the aforementioned documents, and the tank needs to be equipped with a structure to fix the electrode plates, making the assembly process complex and increasing production costs. Therefore, improvements are needed. Utility Model Content

In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.
[0026] like Figures 1 to 3 As shown, this utility model provides an electrode plate device, which includes a positive electrode assembly 10 and a negative electrode assembly 20. The positive electrode assembly 10 and the negative electrode assembly 20 are respectively connected to a power source, thereby enabling the decomposition of harmful substances contained in wastewater within the electrolysis zone; or the decomposition of additives in wastewater through electrolysis to form a gas with bactericidal effect.
[0027] The positive electrode assembly 10 includes a positive electrode conductive plate 12 and multiple positive electrode plates 11 arranged at intervals. The positive electrode conductive plate 12 is connected to the conductive portion of the positive electrode plate 11, and the positive electrode plate 11 has a through-hole 113. The positive electrode plate 11 is a multi-plate structure, wherein the positive electrode conductive plate 12 connects the multiple positive electrode plates 11 in series to form a unified conductive connection. For example, the positive electrode plate 11 is inserted into the positive electrode conductive plate 12 and welded to the positive electrode conductive plate 12 for fixed connection; or, the positive electrode plate 11 is locked to the positive electrode conductive plate 12 by fasteners to achieve adjustable connection. Alternatively, the positive electrode plate 11 is connected to the positive electrode conductive plate 12 by an adapter to form an adapter connection.
[0028] Multiple positive electrode plates 11 are arranged in parallel at intervals. Preferably, the positive electrode plates 11 are distributed at equal intervals.
[0029] The positive electrode plate 11 has a plate-like structure, and a first channel 113 penetrates the plate, thereby connecting the spaces on both sides of the positive electrode plate 11. Optionally, the first channel 113 is an elongated hole; or, the first channel 113 is formed by a combination of multiple holes. Specifically, the first channel 113 is eccentric relative to the center of the positive electrode plate 11. The length direction of the elongated hole is parallel to one side of the positive electrode plate 11; the distance between the elongated hole and this side is much smaller than the distance to the opposite side, thus forming an offset opening structure.
[0030] The negative electrode plate 21 and the positive electrode plate 11 are arranged in an alternating manner. The negative electrode assembly 20 includes a negative electrode conductive plate 22 and multiple negative electrode plates 21 arranged at intervals. The negative electrode conductive plate 22 is connected to the conductive part of the negative electrode plate 21, and the negative electrode plate 21 has a through second channel 211.
[0031] The structure and layout of the negative electrode component 20 are similar to those of the positive electrode component 10. They can be understood by referring to the structure and connection layout of the positive electrode component 10, and will not be described in detail here.
[0032] like Figures 1 to 3 As shown, the positive electrode assembly 10 and the negative electrode assembly 20 are interleaved, so that the positive electrode plate 11 and the negative electrode plate 21 are alternately arranged, and a reaction space 14 is formed between the positive electrode plate 11 and the negative electrode plate 21. The first channel 113 and the second channel 211 are staggered, and adjacent reaction spaces 14 are connected through the first channel 113 or the second channel 211, thereby forming a staggered flow path.
[0033] The positive electrode plate 11 and the negative electrode plate 21 are alternately arranged, and the edges of the positive electrode plate 11 and the negative electrode plate 21 can be confined to the cavity wall of the electrolysis chamber 33. The adjacent reaction spaces 14 are connected through the first channel 113 or the second channel 211. All the reaction spaces 14 are connected by the staggered first channel 113 and the second channel 211 to form a continuous tortuous flow path, thereby realizing liquid flow. This not only extends the reaction time but also avoids large local pressure shocks.
[0034] The structure of the positive electrode plate 11 is the same as that of the negative electrode plate 21. The following description uses the positive electrode plate 11 as an example. The negative electrode plate 21 can be understood by referring to it.
[0035] In one embodiment, the positive electrode plate 11 includes an electrode portion 111 and an extension portion 112 that partially protrudes from one side of the electrode portion 111. The electrode portion 111 and the extension portion 112 are an integral structure. The electrode portion 111 is used to connect to the positive electrode conductive plate 12 to form a conductive connection portion. The electrode portion 111 serves as a reaction surface with a large reaction area. The extension portion 112 is a convex plate structure formed by the partial protrusion of the electrode portion 111. As a conductive connection portion, the extension portion 112 can reduce the installation contact area between the positive electrode plate 11 and the housing, thereby improving the sealing effect.
[0036] The first channel 113 is disposed on the electrode plate portion 111 and spaced apart from the extension portion 112, so that the liquid flow portion and the conductive contact portion of the first channel 113 are misaligned. Optionally, the first channel 113 and the extension portion 112 are located on the same side of the electrode plate portion 111.
[0037] Preferably, the first channel 113 and the extension 112 are located on opposite sides of the electrode portion 111 to create a misalignment of maximum distance.
[0038] More preferably, one side of the extension 112 is flush with one side of the electrode plate 111 to form an approximately L-shaped structure, thereby placing the conductive connection portion of the positive electrode plate 11 at the edge, further increasing the spacing between the positive electrode conductive plate 12 and the negative electrode conductive plate 22, and reducing interference.
[0039] Preferably, the first channel 113 is a rectangular elongated hole, and the first channel 113 and the extension 112 are spaced apart. The length direction of the first channel 113 is parallel to the protrusion direction of the extension 112. The first channel 113 is disposed on the electrode portion 111 and is located away from the extension 112. The first channel 113 can increase the flow area. Optionally, the two ends of the first channel 113 can be rounded.
[0040] Preferably, the positive electrode assembly 10 further includes a bent conductive element 13, which connects the positive electrode plate 11 and the positive electrode conductive plate 12. The conductive element 13 is made of a conductive metal material and can connect the positive electrode plate 11 and the positive electrode conductive plate 12, which facilitates the internal space layout and conductive connection method.
[0041] Preferably, the conductive element 13 is an L-shaped structure, the positive electrode plate 11 is a flat plate structure, the first folded edge 131 of the conductive element 13 is attached and fixed to the side of the extension 112, and the second folded edge 132 of the conductive element 13 is connected to the positive electrode conductive plate 12 so that the positive electrode plate 11 and the positive electrode conductive plate 12 are arranged perpendicularly, and multiple positive electrode plates 11 can be distributed at intervals on the positive electrode conductive plate 12.
[0042] Preferably, the positive electrode conductive plate 12 and the negative electrode conductive plate 22 are arranged side by side with intervals, and the number of positive electrode plates 11 and the number of negative electrode plates 21 are the same, so as to form positive and negative electrodes that conduct electricity and form an electrolysis region. Optionally, the conductive element 13 can be made of copper metal. The number of positive electrode plates 11 and negative electrode plates 21 can be increased to meet the requirements of rapid and efficient electrolysis.
[0043] In one embodiment, the positive conductive plate 12 and the negative conductive plate 22 are on the same plane; the positive conductive plate 12 and the negative conductive plate 22 are arranged side by side at intervals on the same plane, which facilitates the consistency of wiring.
[0044] In another embodiment, the positive conductive plate 12 and the negative conductive plate 22 have a height difference, and the wiring positions of the positive conductive plate 12 and the negative conductive plate 22 have a height difference, which can form a positive and negative wiring part with identification effect. At the same time, it can also be adapted to the changes in the external box space, improving identification and space utilization.
[0045] like Figure 1 and Figure 4 As shown, the electrode plate device disclosed in the above embodiments is applied to an electrolysis module, wherein the electrolysis module includes an electrolysis chamber 30 and the electrode plate device as described above.
[0046] The electrolysis chamber 30 is provided with an electrolysis chamber 33, an input port 32 connected to the electrolysis chamber 33, and an output port 31. The input port 32 is used to input the liquid to be electrolyzed, and the output port 31 is used to output the electrolyzed liquid. The alternating positive electrode plate 11 and negative electrode plate 21 divide the electrolysis chamber 33 to form a continuously tortuous flow path.
[0047] The flow path is approximately S-shaped in three consecutive reaction spaces 14. The three or more reaction spaces 14 are connected by the first channel 113 and the second channel 211, thus forming a continuous tortuous flow path with a long flow path and sufficient liquid electrolysis.
[0048] Specifically, the electrode plate portion 111 of the positive electrode and the electrode plate portion 111 of the negative electrode are located inside the electrolysis chamber 33, and the electrode plate portion 111 is connected to the cavity wall of the electrolysis chamber 33 on all sides, which facilitates the flow of liquid along the flow path and improves the support effect of the electrolysis chamber 33 on the electrode plate portion 111.
[0049] The extension 112 extends through the wall of the electrolysis chamber 33, reducing the opening size of the wall of the electrolysis chamber 33.
[0050] The positive electrode conductive plate 12 and the negative electrode conductive plate 22 are located outside the electrolysis tank 30 for easy power connection. Notably, the positive and negative terminals of the power supply connected to the positive electrode conductive plate 12 and the negative electrode conductive plate 22 are interchangeable, enabling a reversal function. This function automatically removes deposits from the positive electrode plate 11 and the negative electrode plate 21, which are then automatically discharged from the electrolysis tank with the liquid flow, improving electrolysis efficiency and reducing energy consumption.
[0051] In one embodiment, the input port 32 and the flow path channel are misaligned, and the output port 31 and the flow path channel are also misaligned. This misalignment of the input port 32 and the output port 31 extends the path for both initial input and final output, thereby improving the initial reaction time of the electrode plate assembly.
[0052] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of this application and include common knowledge or customary technical means in the art that are not disclosed in this invention.
