Description

Technical Field

[0001] The present invention relates to the technical field of batteries, and in particular to an electrolytic cell, an electrolytic cell group and an electrolytic cell system. Background Art

[0002] As alkaline electrolytic cells become larger and current density increases exponentially, the impact of the bubble effect in the electrolytic cell on energy consumption becomes increasingly greater. Energy-saving solutions to mitigate the increase in chamber resistance and energy consumption caused by the bubble effect have become issues that need to be urgently addressed.

[0003] The current solution to reduce the bubble effect is mainly to add vanadium pentoxide and potassium dichromate to the alkali solution to reduce bubble aggregation and avoid the appearance of large-diameter bubbles, thereby reducing overall power consumption.

[0004] However, vanadium pentoxide and potassium dichromate are carcinogenic hazardous chemicals, which are inconvenient to transport and difficult to treat as waste liquid. Summary of the invention

[0005] The present invention provides an electrolytic cell, an electrolytic cell group and an electrolytic cell system, which are used to solve the defects of the prior art that the method of slowing down the bubble effect by adding a chemical catalyst has the disadvantages of difficulty in waste liquid treatment and easy carcinogenesis, and realizes a method of slowing down the bubble effect in the electrolytic cell by a physical method, which can not only achieve the effect of energy saving, but also avoid the defects of difficulty in waste liquid treatment and carcinogenesis.

[0006] The present invention provides an electrolytic cell, comprising: The electrolytic cell body has an electrolytic chamber inside, and the inner wall of the electrolytic chamber is provided with a plurality of liquid inlets and a plurality of liquid discharge ports, and the liquid inlets and the liquid discharge ports are both connected to the electrolytic chamber; At least one partition is arranged inside the electrolysis chamber, and the partition is used to divide the electrolysis chamber into a plurality of areas, each of which has at least one liquid inlet and a liquid outlet.

[0007] According to the electrolytic cell provided by the present invention, the plurality of liquid discharge ports are distributed at intervals.

[0008] According to the electrolytic cell provided by the present invention, the liquid inlet and the liquid outlet are respectively located on both sides of the central plane of the electrolytic chamber.

[0009] According to the electrolytic cell provided by the present invention, one end of the barrier member is connected to the inner wall of the electrolytic chamber, and the other end of the barrier member extends to the center of the electrolytic chamber.

[0010] According to the electrolytic cell provided by the present invention, the barrier member is streamlined.

[0011] According to the electrolytic cell provided by the present invention, the plurality of liquid inlets are distributed at intervals.

[0012] According to the electrolytic cell provided by the present invention, both ends of the barrier member are connected to the inner wall of the electrolytic chamber.

[0013] According to the electrolytic cell provided by the present invention, the liquid discharge port comprises a liquid discharge channel, a plurality of flow dividers are provided at intervals at one liquid inlet end of the liquid discharge channel, and the flow dividers are used for flow diversion.

[0014] The present invention also provides an electrolytic cell group, comprising a plurality of electrolytic cells as described in any one of the above embodiments, wherein the plurality of electrolytic cells are connected in series or in parallel.

[0015] The present invention also provides an electrolytic cell system, comprising the electrolytic cell as described in any one of the above embodiments, or the electrolytic cell group as described in any one of the above embodiments.

[0016] In the electrolytic cell provided by the present invention, after the alkali solution enters each area through the liquid inlet, each area is provided with an independent liquid discharge port, so that the gas (mainly hydrogen and oxygen) generated during the electrolysis process can be quickly discharged from the nearest liquid discharge port, rather than staying in the reaction area for a long time to form large bubbles. This design effectively reduces the accumulation time and path of bubbles in the reaction area, thereby reducing the additional power consumption caused by the bubble effect, and achieving the goal of energy saving.

[0017] In addition, since separate flow channels are formed between the areas through the baffles, the alkali solution can be made to flow more evenly in the tank, reducing dead zones (i.e. areas where the fluid flows slowly or stagnates), thereby further promoting even heat dispersion. This makes the temperature distribution inside the electrolytic cell more even, further reduces the heat loss during the operation of the electrolytic cell, and improves the operating efficiency of the entire electrolytic cell.

[0018] Furthermore, since the present invention reduces the influence of the bubble effect by physical means, it can also avoid the problem of difficult waste liquid treatment and carcinogenicity caused by the method of using chemical catalysts to slow down the bubble effect.

[0019] Furthermore, since the electrolytic cell group and the electrolytic cell system provided by the present invention both include the above-mentioned electrolytic cells, they also have the above-mentioned beneficial effects. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0030] Combine the following Figure 1-Figure 3 The structure and working principle of the electrolytic cell of the present invention are described in detail.

[0031] Reference Figure 1 The electrolytic cell provided by the present invention includes an electrolytic cell body 100 and at least one partition member 200. The electrolytic cell body 100 has an electrolytic chamber 110 inside. The inner wall of the electrolytic chamber 110 is provided with a plurality of liquid inlets 120 and a plurality of liquid discharge ports 130. The liquid inlets 120 and the liquid discharge ports 130 are both connected to the electrolytic chamber 110. The partition member 200 is arranged inside the electrolytic chamber 110. The partition member 200 is used to divide the electrolytic chamber 110 into a plurality of areas, each area having at least one liquid inlet 120 and a liquid discharge port 130.

[0032] It should be noted that the multiple areas do not necessarily have obvious boundaries, as long as the flow of bubbles is orderly. That is, the multiple areas can be connected or closed and independent of each other. The liquid inlet 120 and the liquid discharge port 130 can be set in a one-to-one correspondence, or one liquid inlet 120 can correspond to multiple liquid discharge ports 130, or multiple liquid inlets 120 can correspond to one liquid discharge port 130, or multiple liquid inlets 120 can correspond to multiple liquid discharge ports 130. When multiple areas are connected, the liquid discharge ports 130 corresponding to each area can share one or more liquid inlets 120.

[0033] The present invention integrates an electrolytic cell body 100 and a barrier member 200. Multiple liquid inlets 120 and liquid discharge ports 130 are distributed inside the electrolytic cell body 100, and the barrier member 200 is used to divide the electrolytic chamber 110 into multiple areas. Each area is equipped with at least one liquid inlet 120 and a liquid discharge port 130. This structural design significantly improves the efficiency and energy-saving effect of the electrolysis process.

[0034] Specifically, after the alkali solution enters each area through the liquid inlet 120, each area is provided with an independent liquid discharge port 130, so that the gas (mainly hydrogen and oxygen) generated during the electrolysis process can be quickly discharged from the nearest liquid discharge port 130, rather than staying in the reaction area for a long time to form large bubbles. This design effectively reduces the gathering time and path of bubbles in the reaction area, thereby reducing the additional power consumption caused by the bubble effect, and achieving the goal of energy saving.

[0035] In addition, since separate flow channels are formed between the regions through the barrier 200, the alkali solution can be made to flow more evenly in the tank, reducing dead zones (i.e., areas where the fluid flows slowly or stagnates), thereby further promoting even heat dispersion. This makes the temperature distribution inside the electrolytic cell more even, further reduces the heat loss during the operation of the electrolytic cell, and improves the operation efficiency of the entire electrolytic cell.

[0036] It should be noted that, considering that the density of gas is relatively small relative to that of alkali solution, bubbles will naturally move vertically upwards. Therefore, when designing the positions of the electrolytic chamber 110 and its inlet 120 and drain 130, it is necessary to make the height of the inlet 120 in the same area lower than the drain 130. Such a setting can ensure that the gas in each reaction area can be quickly discharged from the drain 130 without being retained in the reaction zone for a long time to form larger bubbles. In addition, since the inlet 120 is located at a lower position, the alkali solution can flow smoothly into the reaction zone from the bottom, and the gas is smoothly discharged from the drain 130 above. This fluid dynamics optimization design helps to maintain the pressure balance inside the electrolytic cell, further improving the stability and efficiency of the electrolysis process. Furthermore, this structural design also helps to extend the service life of the electrolytic cell, because while reducing the bubble effect, it also reduces the impact of bubbles on the inner wall of the electrolytic cell and reduces equipment wear. In short, through the above setting, not only the energy consumption problem caused by the bubble effect is solved, but also the operating state of the electrolytic cell is optimized, and the overall work efficiency is improved.

[0037] Reference Figure 1 The present invention provides an electrolytic cell, wherein a plurality of drainage ports 130 are spaced apart. Specifically, the spacing between the plurality of drainage ports 130 is as large as possible, so that the drainage ports 130 are dispersedly arranged. The arrangement of the barrier 200 is arranged along with the arrangement of the drainage ports 130. By dispersing the drainage ports 130, the various areas separated by the barrier 200 from the electrolytic chamber 110 can be more balanced.

[0038] First, due to the large spacing between the discharge ports 130, the gas can be more evenly distributed to each discharge port 130 during the rising process, thereby reducing the accumulation time of bubbles in the reaction zone. This uniform gas discharge path not only reduces the increase in chamber resistance caused by the bubble effect, but also significantly reduces the energy consumption of the electrolytic cell and improves the overall operating efficiency.

[0039] Secondly, the barrier divides the electrolysis chamber 110 into a plurality of more balanced regions, and this balanced division method helps to optimize the fluid dynamics in the electrolyzer. The alkali solution and gas flow in each region are more uniform, avoiding the phenomenon of local flow rate being too fast or too slow. This uniform fluid distribution not only reduces the turbulence and eddy current of the fluid in the reaction zone, but also makes the electrolysis process more stable and controllable. The uniform fluid distribution also helps to maintain the temperature field inside the electrolyzer more uniform, reduces the energy loss caused by local temperature differences, and further improves the electrolysis efficiency.

[0040] Finally, by distributing the drain ports 130 and dividing the baffles evenly, the overall design of the electrolytic cell is more reasonable and scientific. This design not only optimizes the bubble effect management and fluid dynamics during the electrolysis process, but also improves the operating efficiency and reliability of the electrolytic cell. This design shows significant advantages in dealing with large-scale and high current density electrolysis requirements, providing a strong guarantee for the efficient and stable operation of the electrolysis process.

[0041] In some possible embodiments, multiple drain ports 130 may be provided in the same area. With such a configuration, in actual operation, even if a drain port 130 temporarily fails due to blockage or other reasons, other drain ports 130 may still continue to function to ensure smooth gas discharge. This redundant design improves the fault tolerance of the system, reduces the risk of downtime due to failure of a single drain port 130, and extends the service life of the electrolyzer.

[0042] Reference Figure 1 The present invention provides an electrolytic cell, wherein the liquid inlet 120 and the liquid outlet 130 are respectively located on both sides of the center plane of the electrolytic chamber 110. Specifically, when the electrolytic cell is a circular electrolytic cell. Figure 1 As shown, the center plane is a plane passing through the center of the circle, that is, Figure 1 The liquid discharge port 130 is arranged at the upper part of the vertical plane, and the liquid inlet 120 is arranged at the lower part of the vertical plane.

[0043] In the above structure, the liquid inlet 120 is arranged on one side of the central plane, and the liquid outlet 130 is arranged on the other side of the central plane. This layout enables the alkali solution to be evenly distributed along a predetermined path after entering the electrolysis chamber 110 from the liquid inlet 120. This distribution method not only reduces the phenomenon of excessively fast or slow local flow velocity, but also avoids the formation of eddy currents and dead zones in the electrolysis chamber 110, thereby improving the stability and efficiency of the electrolysis process.

[0044] Secondly, when the gas is generated from the reaction zone, it will quickly move to the drain port 130 on the other side of the center plane. Since the drain port 130 is located on the other side of the center plane, the gas can be discharged more directly from the nearest drain port 130 without staying in the reaction zone for a long time. This design effectively reduces the accumulation time of bubbles in the reaction zone and reduces the increase in chamber resistance caused by the bubble effect, thereby significantly reducing the energy consumption of the electrolytic cell and improving the overall operating efficiency.

[0045] Furthermore, this layout helps to maintain a more uniform temperature field inside the electrolytic cell. Since the liquid inlet 120 and the liquid outlet 130 are located on both sides of the center plane, the flow paths of the alkali solution and the gas are more reasonable, avoiding the situation where the local temperature is too high or too low. The uniform temperature distribution not only reduces the energy loss caused by temperature differences, but also prolongs the service life of the components in the electrolytic cell and improves the overall reliability of the system.

[0046] Reference Figure 1 In an electrolytic cell provided by the present invention, one end of the barrier member 200 is fixedly connected to the inner wall of the electrolytic chamber 110 , and the other end of the barrier member 200 extends to the center of the electrolytic chamber 110 .

[0047] It should be noted that, when the liquid inlet 120 and the liquid discharge port 130 are respectively located on both sides of the center plane of the electrolysis chamber 110, one end of the barrier 200 is connected to the inner wall of the electrolysis chamber 110, and the other end of the barrier 200 extends to the center of the electrolysis chamber 110. The center of the electrolysis chamber 110 refers to the middle area of ​​the electrolysis chamber 110. Since the arrangement of the barrier 200 needs to extend from the liquid discharge port 130 to the direction of the liquid inlet 120, and the liquid inlet 120 and the liquid discharge port 130 are respectively located on both sides of the center plane of the electrolysis chamber 110, the other end of the barrier 200 extends to the center of the electrolysis chamber 110 to accurately divide the electrolysis chamber 110. When multiple barrier 200 extend to the center of the electrolysis chamber 110, they are not connected to each other, but form a common area, and the liquid inlet 120 is located in the common area. In this way, multiple electrolytic chambers 110 can share the liquid inlet 120, thereby reducing the number of liquid inlets 120. When the alkali solution enters the electrolytic chamber 110 through the liquid inlet 120, it first enters the common area, then enters each area, and then is discharged through the corresponding liquid discharge port 130.

[0048] Reference Figure 1 In an electrolytic cell provided by the present invention, the barrier member 200 is streamlined.

[0049] The streamlined baffle design can significantly reduce the resistance of the fluid when it flows in the electrolytic chamber 110. Due to its streamlined profile, the alkali solution can flow more smoothly when passing through the baffle, avoiding the eddy currents and turbulence caused by the traditional right-angle or sharp edge design. Secondly, the design of the streamlined baffle helps to further reduce the bubble effect. After the gas is generated during the electrolysis process, it will naturally move upward. The streamlined baffle can guide the gas to be discharged more smoothly from the nearest drain port 130, reducing the residence time and path length of the bubbles in the reaction zone. This design effectively reduces the increase in chamber resistance caused by the bubble effect, thereby significantly reducing the energy consumption of the electrolytic cell and improving the overall operating efficiency.

[0050] In addition, the material selection of the baffle is crucial because it is directly related to the corrosion resistance and mechanical strength of the baffle. In the electrolytic cell, the alkali solution is highly corrosive, so the baffle material must have excellent corrosion resistance. Commonly used materials include: ① Stainless steel: has good corrosion resistance and high mechanical strength, and can be used in most electrolytic environments. ② Titanium alloy: has stronger corrosion resistance and can be used in high-concentration alkali solution and high-temperature environment. ③ Polytetrafluoroethylene (PTFE): has excellent chemical stability and low friction coefficient, and can be used in occasions requiring low friction and high chemical stability. ④ Glass fiber reinforced plastic (FRP): lightweight and corrosion-resistant, can be used in large-sized electrolytic cells.

[0051] In some other possible embodiments, a sealing strip may be provided at the edge of the barrier to ensure effective isolation between the reaction areas and prevent the electrolyte from penetrating each other. The sealing strip may be made of a corrosion-resistant elastic material, such as silicone rubber or fluororubber, to ensure sealing performance during long-term use. In addition, in order to ensure the stability of the barrier in the electrolytic cell, a supporting structure, such as a reinforcing rib or a fixing bracket, may be designed on the barrier. These structures can not only enhance the mechanical strength of the barrier, but also help it maintain a fixed position during the electrolysis process to avoid displacement due to fluid impact.

[0052] The connection between the baffle and the electrolytic cell body 100 may be bolt fixing, welding or snap connection. Bolt fixing is suitable for occasions that require regular maintenance and replacement, welding is suitable for permanent fixation, and snap connection is convenient for quick installation and disassembly, and is suitable for experimental environments that require frequent adjustments.

[0053] Reference Figure 1The present invention provides an electrolytic cell, wherein a plurality of liquid inlets 120 are distributed at intervals. The plurality of liquid inlets 120 are distributed at intervals, so that each area can be divided more evenly, thereby reducing the flow time of the alkali solution.

[0054] In some other possible embodiments, a plurality of guide members (not shown in the figure) may be provided on the liquid inlet 120 , each guide member being arranged toward a corresponding liquid discharge port 130 , so that the alkaline solution can flow directly to the corresponding liquid discharge port 130 .

[0055] In the above structure, by arranging a plurality of guides on the liquid inlet 120 and oriented each guide toward the corresponding liquid discharge port 130, it can be ensured that the alkali solution can flow directly to the corresponding liquid discharge port 130 after entering the electrolysis chamber 110. Since the alkali solution can flow along a preset path, the distribution of the fluid is more uniform and the flow rate is more stable, thereby improving the efficiency of the electrolysis process. It should be noted that when dealing with different current densities and reaction conditions, the performance of the electrolytic cell can be further optimized by adjusting the angle and number of the guides. For example, at high current density, the gas discharge efficiency can be improved by increasing the number of guides, while at low current density, the energy consumption can be reduced by reducing the number of guides.

[0056] Reference Figure 2 In some embodiments of the present invention, both ends of the barrier 200 are fixedly connected to the inner wall of the electrolysis chamber 110. The connection method between the barrier 200 and the electrolysis chamber 110 can be specifically referred to the above-mentioned related embodiments, which will not be repeated here.

[0057] In the above structure, by connecting the two ends of the barrier to the inner wall of the electrolysis chamber 110, complete isolation between each reaction area can be ensured. This strict isolation design prevents the electrolytes in different areas from penetrating each other, and the alkali solution and gas flow in each reaction area are more independent, ensuring the uniformity and consistency of the reaction conditions, thereby improving the stability and efficiency of the electrolysis process. Secondly, this connection design helps to optimize the fluid dynamics in the electrolysis chamber 110. Because the two ends of the barrier are tightly connected to the inner wall, a clear fluid channel is formed, and the alkali solution can be evenly distributed along a predetermined path after entering the electrolysis chamber 110.

[0058] Reference Figure 2 In some embodiments of the present invention, the drain port 130 includes a drain hole 131, and a plurality of flow dividers 132 are fixedly arranged at intervals at one end of the drain hole 131. The plurality of flow dividers 132 can divide the bubbles to avoid forming an air wall on the drain hole 131, so that the drain port 130 can drain better.
