Description

Technical Field

[0001] This utility model relates to the field of physiotherapy device technology, and in particular to a high-flow-rate cathode liquid circulation system for an electrolytic cell. Background Technology

[0002] Electrolytes are crucial equipment in many industrial sectors, including chemical and metallurgical industries, and are widely used in important processes such as metal extraction, electroplating, and water electrolysis for hydrogen production. The performance of an electrolyzer directly affects key indicators such as production efficiency, product quality, and energy consumption. Among these, the catholyte circulation system, as a vital component of the electrolyzer, plays a crucial role in maintaining the stability of the electrolytic reaction. During electrolysis, the catholyte not only provides the necessary reactant ions for the cathode reaction but also performs important functions such as removing reaction products and regulating temperature and concentration distribution within the electrolyzer. Therefore, factors such as the circulation flow rate, uniformity, and supply stability of the catholyte significantly affect the efficiency of the electrolytic reaction, current efficiency, product purity, and electrode life. With the continuous expansion of industrial production scale and increasingly stringent product quality requirements, traditional catholyte circulation systems are no longer sufficient to meet the demands of modern electrolysis processes. Especially in industrial settings with stringent electrolytic reaction conditions and large-scale production, achieving a high-flow-rate, uniform, and stable circulation supply of catholyte has become a key issue in improving electrolyzer performance and production efficiency.

[0003] Existing catholyte circulation systems for electrolytic cells have several design limitations. Most employ a single inlet method, typically placing inlets at one end or a few locations within the electrolytic cell. The catholyte enters through these limited inlets and distributes to the various cathode components via natural diffusion or simple agitation. This inlet method results in highly uneven catholyte distribution within the electrolytic cell. Cathode components closer to the inlet receive a relatively sufficient supply of catholyte, while those farther away are prone to insufficient supply. This uneven catholyte distribution leads to variations in electrolytic reaction conditions across different areas of the cell, resulting in reduced current efficiency and inconsistent product purity. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a high-flow-rate cathode liquid circulation system for electrolytic cells.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-flow-rate catholyte circulation system for an electrolytic cell, wherein multiple cathode assemblies are spaced apart along the length of the electrolytic cell, each cathode assembly including a cathode frame and a cathode plate, the cathode frame having a receiving space for the cathode plate; the high-flow-rate catholyte circulation system includes:

[0007] An inlet pipe is configured to extend below a plurality of cathode assemblies along the length direction, the inlet pipe having an inlet hole disposed below the cathode frame, and an inlet channel for injecting cathodic liquid into the accommodating space is formed between the inlet hole and the cathode frame.

[0008] The liquid inlet channel extends through the bottom of the cathode frame and is fluidly connected to the liquid inlet hole and the accommodating space to form a high-flow-rate circulating supply of cathodic liquid around the cathode plate.

[0009] Furthermore, the inlet pipe includes an inlet section arranged in a vertical direction and an outlet section arranged in a horizontal direction perpendicular to the vertical direction, and the inlet hole is disposed in the outlet section.

[0010] Furthermore, the liquid outlet includes at least one first liquid distribution pipe, which is provided with a liquid inlet hole and the liquid inlet hole is arranged along the width direction of the cathode frame.

[0011] Furthermore, the liquid outlet includes at least one second liquid distribution pipe and a connecting pipe for connecting the second liquid distribution pipe. The connecting pipe is arranged along the width direction of the cathode frame, and the connecting pipe has a liquid inlet along its own length direction.

[0012] Furthermore, each cathode frame corresponds to one or more liquid inlet holes, and the plurality of liquid inlet holes are arranged at different angles in the upward direction to enable the cathodic liquid to be injected into the corresponding cathode plate from different angles.

[0013] Furthermore, the liquid inlet hole is separately disposed from the cathode frame to avoid contact with the cathode frame during the installation of the liquid inlet pipe, thereby preventing the cathode frame from shifting.

[0014] Furthermore, the liquid inlet hole is spaced apart from the cathode plate to prevent the flow rate in the liquid inlet channel from being too fast, which would cause the cathodic liquid to wash over the cathode plate and thus cause defects in the cathode plate.

[0015] Furthermore, the high-flow-rate catholyte circulation system also includes an outlet suitable for circulating the catholyte from the electrolytic cell to the circulation tank, the outlet being disposed in the electrolytic cell.

[0016] Furthermore, the inlet hole is positioned below the outlet hole to achieve a bottom-in, top-out inlet liquid feeding method.

[0017] Furthermore, the high-flow-rate catholyte circulation system also includes an anode assembly, which includes an anode plate and an anode frame fitted outside the anode plate. A diaphragm bag is fitted outside the anode frame, and the diaphragm bag is configured to isolate the anolyte and the catholyte, thereby creating a liquid level difference between the anolyte and the catholyte.

[0018] Due to the adoption of the above technical solutions, this utility model has the following beneficial effects:

[0019] 1. This invention arranges multiple cathode components at intervals along the length of the electrolytic cell and provides a liquid inlet pipe extending below the cathode components along the length. A liquid inlet channel is formed between the liquid inlet hole and the cathode frame, penetrating the bottom of the cathode frame and fluidly communicating with the liquid inlet hole and the accommodating space. This design allows catholyte to be injected directly into the surrounding accommodating space of each cathode plate at a high flow rate. The ample supply of catholyte ensures that the reactant ions required for the cathode reaction can reach the electrode surface in a timely manner, thereby improving the reaction rate and making the electrolysis process more efficient.

[0020] 2. The present invention features a separate inlet pipe from the cathode frame. This design solves the problem in traditional processes where the inlet pipe is damaged by the metal plate (cathode plate) due to cathode frame adhesion or jamming. This avoids disruption to normal production caused by pipe damage. The independently positioned inlet pipe maintains a distance from the cathode frame, making the installation structure of the inlet pipe within the electrolytic cell more stable and unaffected by cathode frame movement or the removal of the metal plate (cathode plate), thus improving system reliability. Furthermore, the anode bagging process frees up space in the cathode chamber, allowing for high-flow-rate cathodic liquid circulation. Under high-flow-rate cathodic liquid circulation conditions, the inlet hole of the inlet pipe will not become blocked. Moreover, the temperature and composition of the high-flow-rate circulating solution are more uniform, which is beneficial for the electrowinning reaction.

[0021] 3. This invention offers flexible and diverse circulation methods. When the inlet component is positioned at the bottom of the cathode frame, below the outlet, a bottom-in, top-out inlet method can be achieved. This method ensures the catholyte is fully filled within the cathode frame and makes full contact with the cathode plate, improving the uniformity and efficiency of the electrolysis reaction. When the inlet component is positioned at the top of the cathode frame, above the outlet, a top-in, bottom-out inlet method can be achieved. This method utilizes the gravity of the catholyte to create a certain flow pressure within the cathode frame, promoting catholyte circulation.

[0022] 4. In this invention, each cathode frame corresponds to one or more liquid inlet holes. The multiple liquid inlet holes are arranged at different angles in the upward direction, which can realize the cathodic liquid being injected into the corresponding cathode plate from different angles, thereby further enhancing the contact effect between the cathodic liquid and the cathode plate.

[0048] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0049] Please see Figures 1-3This utility model discloses a high-flow-rate cathodic liquid circulation system for an electrolytic cell 100. The electrolytic cell 100 has multiple cathode assemblies 200 arranged at intervals along its length. Each cathode assembly 200 includes a cathode frame 210 and a cathode plate 220. The cathode frame 210 has a receiving space 211 for the cathode plate 220. The main function of the high-flow-rate cathodic liquid circulation system is to provide a high-flow-rate cathodic liquid circulation supply to the cathode plate 220, ensuring the stability and efficiency of the electrolysis process. The inlet pipe 300 is one of the key components of the high-flow-rate cathodic liquid circulation system, configured to extend below the multiple cathode assemblies 200 along the length of the electrolytic cell 100. The inlet pipe 300 includes a vertically arranged inlet section 310 and an outlet section 320 arranged in a horizontal direction perpendicular to the vertical direction. The inlet section 310 is used to connect to the external catholyte circulation tank and introduce catholyte into the inlet pipe 300; the outlet section 320 is used to distribute the catholyte to each cathode assembly 200. This high-flow-rate catholyte circulation system also includes an anode assembly 500, which includes an anode plate 510 and an anode frame 520 sleeved outside the anode plate 510. A diaphragm bag 600 is sleeved outside the anode frame 520, which is configured to isolate the anolyte and the catholyte and create a liquid level difference between the anolyte and the catholyte. In this embodiment, the inlet pipe 300 has an inlet state. In the inlet state, a power source pumps the catholyte from the external catholyte circulation tank, delivers it to the inlet pipe 300 via the electrolytic cell 100, and then distributes the catholyte to the cathode frame 210 corresponding to each cathode plate 220 through the inlet hole 301. The catholyte overflows from the electrolytic cell 100 and flows back to the circulation tank to achieve the circulation flow of the catholyte.

[0050] In this embodiment, the liquid outlet 320 includes at least one first liquid distribution pipe 321, on which a liquid inlet 301 is disposed, and the liquid inlet 301 is arranged along the width direction of the cathode frame 210. In this embodiment, the number of first liquid distribution pipes 321 can be reasonably set according to the size of the electrolytic cell 100 and the number of cathode assemblies 200. For example, for a medium-sized electrolytic cell 100, two first liquid distribution pipes 321 can be set, located on both sides of the electrolytic cell 100 respectively, to ensure that the cathodic liquid can be evenly distributed to each cathode assembly 200. A liquid inlet channel 400 suitable for injecting cathodic liquid into the accommodating space 211 is formed between the liquid inlet 301 and the cathode frame 210. The liquid inlet channel 400 penetrates the bottom of the cathode frame 210 and fluidly communicates with the liquid inlet 301 and the accommodating space 211. To ensure the unobstructed flow of the inlet channel 400, a corresponding flow guiding structure, such as a flow guide groove or flow guide hole, can be provided at the bottom of the cathode frame 210 to guide the catholyte smoothly into the receiving space 211. In other embodiments, the outlet section 320 includes at least one second distribution pipe 322 and a connecting pipe 323 for connecting the second distribution pipe 322. The second distribution pipe 322 is arranged along the length direction of the electrolytic cell, and the connecting pipe 323 is arranged along the width direction of the cathode frame 210 (electrolytic cell), and the connecting pipe 323 has an inlet along its own length direction. The function of the connecting pipe 323 is to connect the second distribution pipes 322 into a whole and distribute the catholyte to each cathode frame 210 through the inlet. In this embodiment, each cathode frame 210 corresponds to one or more inlet holes 301, and the multiple inlet holes 301 are arranged at different upward angles to realize that the catholyte is injected into the corresponding cathode plate 220 from different angles. This design can make the catholyte flow more uniformly around the cathode plate 220, thereby improving the electrolysis efficiency. For example, the angle of the liquid inlet 301 can be set to 30°, 45° and 60° to meet different electrolysis requirements.

[0051] To prevent excessively high flow rates within the inlet channel 400 from causing the cathode liquid to wash over the cathode plate 220 and thus create scratches, the inlet hole 301 is spaced slightly from the cathode plate 220. The high-flow-rate cathode liquid circulation system also includes an outlet 110 suitable for circulating the cathode liquid from the electrolytic cell 100 to the circulation tank. The outlet 110 is located within the electrolytic cell 100. The position and number of outlets 110 significantly affect the cathode liquid circulation effect. In this embodiment, the inlet hole 301 is positioned below the outlet 110 to achieve a bottom-in, top-out inlet configuration. This inlet configuration allows the cathode liquid to flow upwards within the electrolytic cell 100, thereby increasing the contact area and contact time between the cathode liquid and the cathode plate 220, and enhancing the electrolysis effect.

[0052] The following are specific embodiments of this application:

[0053] Example 1:

[0054] Please see Figure 4 , Figure 5 In this embodiment, the power source pumps the catholyte from the external catholyte circulation tank and into the electrolytic cell 100 via the inlet pipe 300.

The pipe has inlet holes 301 according to the position and spacing of the cathode frames. There are 1 to 3 inlet holes 301 corresponding to each cathode frame 210, and the inlet holes 301 are at different upward angles. The catholyte is distributed to the cathode frame 210 corresponding to each cathode plate 220 through the inlet holes 301. After that, the catholyte overflows through the outlet 110 and flows back to the circulation tank to realize the circulation of the catholyte.

[0055] Example 2:

[0056] Please see Figures 6-8 The difference between this embodiment and Embodiment 1 is that the power source pumps the catholyte from the external catholyte circulation tank and into the electrolytic cell 100 via the inlet pipe 300.

Inlet holes 301 are formed in the bottom pipes according to the position and spacing of the cathode frames 210. In this embodiment, each cathode frame 210 has 2 to 6 inlet holes 301, and the inlet holes 301 are at different upward angles. The catholyte is distributed to the cathode frame 210 corresponding to each cathode plate 220 through the inlet holes 301. The catholyte overflows through the outlet 110 and flows back to the circulation tank to achieve the circulation of the catholyte.

[0057] Example 3:

In this embodiment, the outlet section 320 includes two second distribution pipes 322 at the bottom, which are located on both sides of the center line in the width direction of the electrolytic cell 100. The outlet section 320 also includes connecting pipes 323 between the two bottom second distribution pipes 322, which are increased according to the position and spacing of the cathode frame 210. The connecting pipes 323 are horizontally connected to the bottom connecting pipes. Inlet holes 301 with different upward angles are opened along the length direction of each connecting pipe 323, and the number of inlet holes 301 on each connecting pipe 323 is 5 to 15. The catholyte is distributed to the cathode frame 210 corresponding to each cathode plate 220 through the inlet holes 301. Then, the catholyte overflows through the outlet 110 and flows back to the circulation tank to realize the circulation flow of the catholyte.

[0059] Example 4:

In this embodiment, the outlet section 320 includes two second distribution pipes 322 at the bottom, which are located on both sides of the center line in the width direction of the electrolytic cell 100. The outlet section 320 also includes connecting pipes 323 that increase between the bottom second distribution pipes 322 according to the position and spacing of the cathode frame 210. In this embodiment, the height of the connecting pipes 323 is higher than that of the bottom second distribution pipes 322. The height of the connecting pipes 323 can be adjusted as needed, and inlet holes 301 with different upward angles are opened along the direction of each connecting pipe 323. The number of inlet holes 301 on each connecting pipe 323 is 5 to 15. The catholy liquid is distributed to the cathode frame 210 corresponding to each cathode plate 220 through the inlet hole 301. Then, the catholy liquid overflows through the outlet 110 and flows back to the circulation tank to realize the circulation flow of the catholy liquid.

[0061] Example 5:

[0062] Please see Figure 17 , Figure 18 The difference between this embodiment and Embodiment 1 is that the power source pumps the catholyte from the external catholyte circulation tank, and it enters the electrolytic cell 100 downwards through the inlet pipe 300. In this embodiment, the outlet section 320 includes a second distribution pipe 322 at the bottom. Above the bottom second distribution pipe 322, an upper connecting pipe 323 is added according to the position and spacing of the cathode frame 210, and the upper connecting pipe 323 is higher than the bottom pipe 722. The height of the upper connecting pipe 323 can be adjusted as needed. Inlet holes 301 with different upward angles are opened along the direction of each upper connecting pipe 323, and the number of inlet holes 301 on each upper connecting pipe 323 is 5 to 15.
