Description

Technical Field

[0001] The present application relates to the field of electrochemical technology, and primarily to an electrochemical device for an electrochemical reaction device. Background Art

[0002] Electrochemical technology has extremely wide applications in industries such as energy, chemical industry, and water treatment. The electrochemical test system consists of multiple components, such as electrolytic cells, product separation systems, frames, and electrical control systems. As the core of the electrochemical test system, the electrolytic cell is composed of multiple components with different functions to achieve uniform distribution of reactants, separation of products and electrode materials, good electrical contact of electrode components, material isolation of the anode and cathode chambers, and isolation of the electrolytic cell from the outside world. It is necessary to balance and optimize various performance requirements to achieve optimal overall performance. The two electrodes of the electrolytic cell can produce products of different properties, such as oxidation products produced by the anode and reduction products produced by the cathode. In production, most of the time, it is necessary to obtain electrode products of higher purity. Among them, the sealing between the anode and cathode and between the electrolytic cell and the outside world is crucial.

[0003] The electrolytic cells commonly used in industry are composed of at least two flat electrodes. The structural optimization of the electrolytic cell components can provide strong support for efficient production, testing, and research and development. In order to meet the needs of assembly, testing and production, the electrolytic cell needs to be easy to assemble and disassemble, easy to seal, and able to easily form good internal electrical contact to reduce the internal resistance of the electrolytic cell. The current electrolytic cell structure has problems such as inconvenient assembly, complex structure, poor performance repeatability, low heating efficiency and poor adaptability. In addition, the assembly of the electrolytic cell is prone to excessive impedance and fluid leakage, resulting in poor performance of the electrolytic cell or even unsafe operation.

[0004] In summary, it is of great significance to develop an electrochemical device that is easy to install, has good sealing, high heating efficiency, good performance repeatability and high adaptability. Utility Model Content

[0005] In response to the technical problems in the prior art, the present application proposes an electrochemical device for an electrochemical reaction equipment.

[0006] The utility model proposes an electrochemical device of an electrochemical reaction equipment, comprising: a first electrode plate, a second electrode plate and a connecting piece; the first electrode plate and the second electrode plate have opposite polarities; the first electrode plate is provided with a first reaction chamber, a first electrode column, a first liquid inlet and a first liquid outlet; the second electrode plate is provided with a second reaction chamber, a second electrode column, a second liquid inlet and a second liquid outlet; the first reaction chamber and the second reaction chamber form a reaction space for an electrochemical reaction; the first liquid inlet and the first liquid outlet are both connected to the first reaction chamber; the second liquid inlet and the second liquid outlet are both connected to the second reaction chamber; the first electrode plate and the second electrode plate are fixedly connected to a mounting platform via the connecting piece.

[0007] The electrochemical device has a simple structure and can construct an electrochemical reaction space with excellent sealing performance using only two electrode plates. At the same time, the simple structure increases the adaptability of the electrochemical device and can adapt to different installation platforms. The compact structure effectively reduces the volume, thereby making the heating efficiency higher.

[0008] Preferably, the first reaction chamber is arranged on the inner surface of the first electrode plate, and the second reaction chamber is arranged on the inner surface of the second electrode plate. The inner surface of the first electrode plate and the inner surface of the second electrode plate are respectively two contact surfaces of the first electrode plate and the second electrode plate.

[0009] The two reaction chambers are distributed over the same area, and when the two plates are fixed and installed, their boundaries completely overlap, forming a tightly closed electrochemical reaction space. This wide flow path within the electrochemical reaction space allows for good liquid flow, eliminating the need for excessive water pressure and extending the life of the electrolyte membrane.

[0010] Preferably, the first liquid inlet and the first liquid outlet are respectively arranged on the left and right opposite sides of the first electrode plate; the second liquid inlet and the second liquid outlet are respectively arranged on the left and right opposite sides of the second electrode plate.

[0011] The anode and cathode plates have their own liquid inlets and outlets, and are connected to their own internal reaction chambers, which greatly optimizes the fluid pipeline design and makes the fluid pipeline layout more simple and efficient. Moreover, compared with the arrangement method in which the liquid inlet and outlet are arranged at the connection between the electrochemical device and the electrochemical reaction equipment, this solution has higher adaptability to different installation platforms and is conducive to improving the disassembly and assembly efficiency.

[0012] Preferably, the interfaces of the first liquid inlet, the first liquid outlet, the second liquid inlet and the second liquid outlet are all provided with threads.

[0013] The threaded design of the liquid inlet and outlet can improve the efficiency of disassembly and assembly of the fluid pipeline and can effectively prevent fluid leakage.

[0014] Preferably, the first pole is arranged at the top of the first pole plate; the second pole is arranged at the top of the second pole plate.

[0015] This design facilitates the matching of banana sockets, making the overall structure easy to disassemble and assemble and highly adaptable. In addition, the pole is easy to install, low in cost, and has a large contact area and low contact resistance, which can improve the safety of the device.

[0016] Preferably, the connector is a threaded connector.

[0017] Further preferably, both the first electrode plate and the second electrode plate are provided with connecting through holes.

[0018] Further preferably, the connecting through-holes are arranged around the distribution area of the first reaction chamber and / or the second reaction chamber to avoid the distribution area of the first reaction chamber and / or the second reaction chamber, and the distribution area of the connecting through-holes is arranged at an angle to the distribution area of the first reaction chamber and / or the second reaction chamber.

[0019] The threaded connection structure is relatively simple and easy to install. The electrode plate is directly fixed on the installation platform of the electrochemical reaction equipment through the threaded connection parts, and can be easily disassembled and assembled. Multiple sets of threaded connection structures are dispersed around the distribution area of the reaction chamber to provide stable connections, ensure the formation of a well-sealed electrochemical reaction space, and avoid fluid leakage.

[0020] Preferably, the electrochemical device further comprises a proton exchange membrane containing a catalyst, and the proton exchange membrane is installed between the first reaction chamber and the second reaction chamber.

[0021] Compared with the prior art, this application has the following beneficial effects:

[0022] The electrochemical device of the electrochemical reaction equipment of this application features a simple structure, excellent sealing performance, a small size, high heating efficiency, easy assembly and disassembly, good test repeatability, and extremely high adaptability. Furthermore, the unique flow channel design and liquid inlet and outlet methods ensure good fluidity, eliminating the need for high water pressure during operation and effectively extending the service life of the proton exchange membrane.
