Description

Technical Field

[0001] The utility model relates to the field of hydrogen production by electrolyzing water and electrolytic cells, in particular to a transparent replaceable plate electrolytic cell. Background Art

[0002] Currently, in hydrogen production by electrolyzing water, an electrolytic cell is usually used for operation. The existing design and application technologies of electrolytic cells are relatively mature, but there are still some significant deficiencies, which limit the efficiency of the electrolysis process, the monitoring and control accuracy, as well as the maintenance and optimization of the equipment.

[0003] 1. Lack of visual monitoring: Traditional electrolytic cells are mostly made of opaque materials, making it impossible to directly observe the internal reaction process. As a result, researchers cannot monitor in real time phenomena such as the flow field, flow velocity, electrode reaction, bubble generation, and deposit formation during the electrolysis process, which limits the in-depth understanding of the reaction mechanism and the optimization of the performance of the electrolytic cell.

[0004] 2. Difficulty in detection and analysis:

[0005] Due to the lack of transparency, many phenomena inside the electrolytic cell can only be detected and analyzed indirectly, such as using electrochemical tests and sample analysis methods. This not only increases the complexity of experiments and operations, but may also lead to data errors, affecting the accuracy and reliability of the results.

[0006] 3. Limitations in equipment design and optimization:

[0007] When designing and optimizing an electrolytic cell, it is impossible to directly observe the internal reaction process, making the design improvement more dependent on the feedback of experimental results rather than real-time observation. This method is not only inefficient, but also prone to missing some potential problems, resulting in a slow process of equipment optimization.

[0008] 4. Difficulty in maintenance and troubleshooting:

[0009] During the long-term operation of the electrolytic cell, problems such as electrode corrosion and deposit accumulation may occur. Due to the closed nature of traditional electrolytic cells, maintenance personnel cannot directly view the internal condition of the electrolytic cell, making troubleshooting and maintenance work more difficult and time-consuming.

[0010] 5. Safety hazards:

[0011] It is difficult to detect abnormal phenomena in a timely manner during the operation of a closed and opaque electrolytic cell, such as overheating, leakage, or uneven reaction, increasing the safety risks of operation. Summary of the Utility Model

[0012] The technical problem to be solved by the present utility model is: in order to overcome the problems existing in the prior art, such as the inability to visually monitor, the difficulty in detection and analysis, the limitation in equipment design and optimization, the difficulty in maintenance and troubleshooting, and the potential safety hazards, the present utility model provides an electrolytic cell with a transparent shell and replaceable electrodes, which has a transparent property, enabling the internal reaction process to be visualized, thereby improving the monitoring and control accuracy of the electrolysis process, optimizing the design and maintenance efficiency, and enhancing the safety of operation.

[0013] The technical solution adopted by the present utility model to solve its technical problem is: an electrolytic cell with a transparent and replaceable electrode plate, comprising a cathode electrode plate, a diaphragm, and an anode electrode plate; the cathode electrode plate is hermetically arranged on one side surface of the diaphragm, and a cathode chamber is formed between the cathode electrode plate and the surface of the diaphragm. Liquid inlet and outlet openings are respectively provided on the cathode electrode plate corresponding to the cathode chamber; the anode electrode plate is hermetically arranged on the other side surface of the diaphragm, and an anode chamber is formed between the anode electrode plate and the surface of the diaphragm. Liquid inlet and outlet openings are respectively provided on the anode electrode plate corresponding to the anode chamber; perforated plates supported between the partition plate and the corresponding electrode plate are provided in both the cathode chamber and the anode chamber; the cathode electrode plate and the anode electrode plate are transparent electrode plates.

[0014] In the above solution, in view of the lack of visual monitoring means in the existing electrolytic cell, the electrode plates are designed as transparent electrode plates. The combined electrolytic cell has a transparent property, enabling the internal reaction process to be visualized, thereby improving the monitoring and control accuracy of the electrolysis process, optimizing the design and maintenance efficiency, and enhancing the safety of operation.

[0015] Preferably, the transparent electrode plate is a quartz glass electrode plate or a borosilicate glass electrode plate or a transparent polymer material electrode plate. The electrode plate made of quartz glass or borosilicate glass or transparent polymer material has high transparency, providing guarantee for the visual monitoring of the electrolytic cell.

[0016] Furthermore, the inner wall surface of the cathode electrode plate corresponding to the cathode chamber protrudes with a number of protrusions distributed at intervals; the inner wall surface of the anode electrode plate corresponding to the anode chamber also protrudes with a number of protrusions distributed at intervals; the protruding surfaces of the protrusions are respectively in contact with the surfaces of the corresponding perforated plates on the corresponding sides, and the arrangement is reasonable to ensure the uniform flow of the electrolyte and the uniform distribution of the electric field.

[0017] Even further, the protruding surfaces of the cathode electrode plate and the anode electrode plate both have electrode coatings.

[0018] Still further, the electrode coating is a platinum metal coating or a titanium metal coating or a ruthenium metal coating, which is used to ensure the stability and high efficiency of the electrode during the electrolysis process.

[0019] Further, to ensure the sealing of the cathode chamber and the anode chamber, the cathode plate and the diaphragm, as well as the anode plate and the diaphragm, are respectively sealed and connected through gaskets.

[0020] Furthermore, the gasket is in a frame structure, and the orifice plate is in a plate-like structure imitating the inner wall of the frame structure corresponding to the inner wall of the frame structure, and a plurality of holes are evenly spaced on the plate-like structure.

[0021] Based on the above structure, to ensure that the gas or precipitate generated during the electrolysis process does not affect the transparency, the large electrolytic cell can be divided into multiple small electrolytic cells, and the disassembly, installation and combination are reasonably arranged. Specifically, the transparent replaceable plate electrolytic cell further includes a plurality of electrolytic cells connected in series or in parallel, and the positions of the cathode and anode plates of two adjacent electrolytic cells are arranged in opposite directions. That is, the original large electrolytic cell can be divided into multiple small modular electrolytic cells, and the layout is reasonable to prevent mutual interference between different electrodes.

[0022] The beneficial effects of the present utility model are as follows: The transparent shell replaceable plate electrolytic cell provided by the present utility model has a reasonable structural design. By designing transparent plates, the electrolytic cell is visible, and it can be monitored and observed in real time during the electrolysis process, allowing direct observation of the changes occurring during the electrolysis process, such as bubble generation, electrode reaction, flow field velocity, precipitate formation, etc. This helps to study and understand the mechanism of the electrolysis process, enabling researchers to quickly identify and solve problems that occur during the electrolysis process, thereby optimizing process parameters and improving electrolysis efficiency and product quality. At the same time, on the premise of visualization, by reasonably arranging and combining the electrolytic cells, it can be ensured that the gas or precipitate generated during the electrolysis process does not affect the transparency, and the square plates of a single small electrolytic cell can be disassembled and replaced.

[0028] The utility model is now described in further detail in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, so they only show the components related to the utility model, and the directions and references (for example, up, down, left, right, etc.) can only be used to help describe the features in the drawings. Therefore, the following specific embodiments are not adopted in a restrictive sense, and the scope of the subject matter claimed is limited only by the attached claims and their equivalents.

[0029] Embodiment 1:

[0030] like Figure 1 and Figure 2 The transparent electrolytic cell with replaceable polar plates is the first embodiment of the utility model.

[0031] The transparent replaceable plate electrolytic cell comprises a cathode plate 1, a diaphragm 5 and an anode plate 2. In actual assembly, the cathode plate 1 and the anode plate 2 are fixedly connected by bolts.

[0032] The cathode plate 1 is sealed and arranged on the surface of one side of the diaphragm 5, and a cathode chamber is formed between the cathode plate 1 and the surface of the diaphragm 5. The anode plate 2 is sealed and arranged on the surface of the other side of the diaphragm 5, and an anode chamber is formed between the anode plate 2 and the surface of the diaphragm 5. A liquid inlet 3 and a liquid outlet 4 are respectively opened on the cathode plate 1 corresponding to the cathode chamber. A liquid inlet 3 and a liquid outlet 4 are also respectively opened on the anode plate 2 corresponding to the anode chamber. A connecting pipe is provided on the liquid inlet 3 and the liquid outlet 4 on the cathode plate 1 and the anode plate 2 for inputting and outputting electrolyte to and from the corresponding chamber.

[0033] The cathode chamber and the anode chamber are both provided with a perforated plate 7 supported between the separator and the corresponding plate. In order to ensure the sealing of the cathode chamber and the anode chamber, the cathode plate 1 and the diaphragm 5, and the anode plate 2 and the diaphragm 5 are sealed and connected by sealing gaskets 8. The sealing gasket 8 is a frame-shaped structure, and the perforated plate 7 corresponds to the inner wall of the frame-shaped structure and is a plate-shaped structure that imitates the inner wall of the frame-shaped structure, and a plurality of holes are evenly arranged on the plate-shaped structure.

[0034] The cathode plate 1 and the anode plate 2 are transparent plates. The material of the transparent plate needs to be corrosion-resistant, high-temperature-resistant and transparent, and can usually be made of, but not limited to, quartz glass, borosilicate glass or transparent polymer materials.

[0035] like Figure 3As shown, on this basis, in the setting of the electrodes, the corresponding electrode plates need to be designed in cooperation with the electrodes. In the first embodiment, the electrodes are provided with protrusions 6 protruding from the inner wall surface of the electrode plates, and the protrusions 6 are used as electrodes. The cathode electrode plate 1 has a number of protrusions 6 uniformly arrayed on the inner wall surface corresponding to the cathode chamber; the anode electrode plate 2 also has a number of protrusions 6 uniformly arrayed on the inner wall surface corresponding to the anode chamber. The protruding surfaces of the protrusions 6 are respectively in contact with the surfaces of the corresponding side orifice plates 7. In the actual electrode setting, the protrusions 6 themselves can be made of the metal materials required for the motor, or a coating can be designed on the surface of the protrusions 6 so that the protrusions 6 are used as electrodes.

[0036] In the first embodiment, the surfaces of the protrusions 6 of the cathode electrode plate 1 and the anode electrode plate 2 both have electrode coatings. The electrode coatings are metal coatings made of precious metals such as platinum, titanium, ruthenium or their metals, which are used to ensure the stability and high efficiency of the electrodes during the electrolysis process. In the actual assembly, the protrusions 6 of the cathode electrode plate 1 and the anode electrode plate 2 are arranged in one-to-one correspondence, and the holes of the orifice plates in the cathode chamber and the anode chamber are also arranged in one-to-one correspondence. Through the reasonable arrangement of the electrodes, the uniform flow of the electrolyte and the uniform distribution of the electric field are ensured.

[0037] The transparent replaceable electrode plate electrolytic cell provided in the above-mentioned first embodiment, with the electrode plates designed to be transparent and visual, has the following excellent effects:

[0038] 1. Real-time monitoring and observation

[0039] The transparent electrolytic cell allows direct observation of the changes occurring during the electrolysis process, such as bubble generation, electrode reactions, flow field flow rates, precipitate formation, etc., which helps to study and understand the mechanism of the electrolysis process.

[0040] 2. Process optimization

[0041] Real-time observation enables researchers to quickly identify and solve problems occurring during the electrolysis process, thereby optimizing process parameters and improving electrolysis efficiency and product quality.

[0042] Embodiment Two:

[0043] As Figure 2 shown, a transparent replaceable electrode plate electrolytic cell is the second embodiment of the present utility model.

[0044] In order to ensure that the gases or precipitates generated during the electrolysis process do not affect the transparency, in the second embodiment, based on the first embodiment, the large electrolytic cell can be reasonably arranged and separated into multiple small electrolytic cells through reasonable layout. The small electrolytic cells adopt the transparent replaceable electrode plate electrolytic cell provided in the first embodiment. By arranging multiple first embodiments and combining them with the bracket 8 to form the second embodiment, the production requirements of traditional large electrolytic cells can be met, and it is also convenient for maintenance and replacement.

[0045] The transparent replaceable plate electrolytic cell includes a number of electrolytic cells connected in series or parallel according to actual production requirements. The plate positions of the cathodes and anodes of two adjacent electrolytic cells are arranged in opposite directions. That is, the original large electrolytic cell can be divided into multiple small modular electrolytic cells, and a reasonable layout is adopted to prevent mutual interference between different electrodes. In the second embodiment, the number of electrolytic cells is four, arranged in a 2*2 array. In actual assembly, the electrolytic cell in the upper left corner has the cathode side facing the front, and the electrolytic cell in the upper right corner...

[0046] During the electrolysis process, the gas or precipitate generated by electrolysis may affect the transparency of the transparent plate. Through the design of the second embodiment, the large electrolytic cell is divided into multiple regions, so that the second embodiment can not only achieve the production of the large electrolytic cell, but also reduce the production of each small modular electrolytic cell, and can reduce the transparency impact of the gas or precipitate to an acceptable range, ensuring the smooth progress of visual monitoring. Even if there is too much gas or precipitate in a single small modular electrolytic cell, the single electrolytic cell can be quickly disassembled and replaced. At the same time, the installation positions of the divided electrolytic cells are reasonably distributed to prevent mutual interference between different electrodes, further ensuring the electrolysis stability and electrolysis efficiency after the division of the regions.

[0047] Taking the above ideal embodiment based on the present invention as an inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
