Technical Field

[0002] The electrolyzer is a vital piece of equipment widely used in electrolysis processes. It uses an electric current to drive redox reactions between ions in the electrolyte, thereby producing hydrogen. With the continuous advancement of industrial technology, the requirements for electrolyzer efficiency and stability are becoming increasingly stringent. In industrial applications of hydrogen production by electrolysis of water, alkaline electrolyzers are widely used due to their low cost and mature technology.

[0003] However, the existing alkaline electrolytic cells still have some shortcomings in the design of the liquid inlet. Traditional alkaline electrolytic cells usually use multiple interfaces to introduce alkaline solution, which not only increases the complexity of installation and maintenance, but also takes up a large amount of space. It may also cause uneven distribution of alkaline solution and affect electrolysis efficiency.

[0004] To this end, the utility model provides a liquid inlet pipe joint for an electrolytic cell. Utility Model Content

[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] In the present utility model, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] Combined with Figure 1 and Figure 2 As shown, the present utility model provides a pipeline joint for the liquid inlet of an electrolytic cell, which evenly distributes the lye into the small chambers of the electrolytic cell through a primary shunt, improving the uniformity and efficiency of the lye distribution.

[0028] Combined with Figure 1 and Figure 2 As shown, one end of the main pipeline 1 of the liquid inlet is connected to the flange 11, and the main pipeline 1 of the liquid inlet is connected to the external pipeline through the flange 11, enabling the lye to smoothly enter the interior of the main pipeline 1 of the liquid inlet. The other end of the main pipeline 1 of the liquid inlet is connected with a pipe cap 12 to prevent the liquid from flowing out.

[0029] Combined with Figure 1 and Figure 2 As shown, a quick coupling 13 is provided on the main pipeline 1 of the liquid inlet. When the electrolytic cell needs to be repaired, the staff can conveniently release the lye through the quick coupling 13, thereby reducing the risks during the repair process and the inconvenience during the operation process.

[0030] Combined with [[ID=2८]] Figure 1 and Figure 2 As shown, the side wall of the main pipeline 1 of the liquid inlet is connected with a plurality of sub-pipelines 2 for the liquid inlet to ensure that the lye can smoothly enter each part of the electrolytic cell. There are a plurality of sub-pipelines 2 for the liquid inlet, and the sub-pipelines 2 for the liquid inlet connected to both sides of the main pipeline 1 of the liquid inlet are symmetrically arranged about the central axis of the main pipeline 1 of the liquid inlet. Among them, the sub-pipeline 2 for the liquid inlet close to the pipe cap 12 is relatively centered, and the sub-pipeline 2 for the liquid inlet far from the pipe cap 12 is relatively outward. The sub-pipeline 2 for the liquid inlet includes a sub-pipeline liquid inlet part 21 and a sub-pipeline liquid outlet part 22, etc. Among them, one end of the sub-pipeline liquid inlet part 21 is connected to the side wall of the main pipeline 1 of the liquid inlet, the other end of the sub-pipeline liquid inlet part 21 is connected to one end of the sub-pipeline liquid outlet part 22 through an elbow 23, and the other end of the sub-pipeline liquid outlet part 22 is connected to the electrolytic cell through a flange plate 3.

[0031] The sub-pipeline 2 of the liquid inlet adopts a modular design. The liquid inlet part 21 and the liquid outlet part 22 of the sub-pipeline are connected by an elbow 23 to form a complete liquid inlet system. When local problems occur in the sub-pipeline 2 of the liquid inlet and need to be repaired or replaced, the problematic pipeline can be flexibly replaced, without the need for overall replacement, which can save certain economic costs. This modular design makes the installation and disassembly of the sub-pipeline 2 of the liquid inlet more convenient, and at the same time ensures the uniformity of liquid inlet and the compactness of the structure. At the same time, the sub-pipeline 2 of the liquid inlet is arranged on both sides of the main pipeline 1 of the liquid inlet, making the pipeline joint of the electrolytic cell liquid inlet relatively more compact in structural design and reducing the space occupation. At the same time, the diameter of the main pipeline 1 of the liquid inlet is larger than that of the sub-pipeline 2 of the liquid inlet, which can ensure the efficiency of the caustic liquid inlet process.

[0032] As Figure 2 shown, the flange plate 3 is used to fix the sub-pipeline 2 of the liquid inlet. The ends of the sub-pipelines 2 of the liquid inlet on the same side of the main pipeline 1 of the liquid inlet are all connected to the same flange plate 3, which can improve the overall stability of the pipeline joint of the electrolytic cell liquid inlet. A tight connection is formed between the flange plate 3 and the electrolytic cell, ensuring a firm connection between the pipeline joint of the liquid inlet and the electrolytic cell, effectively preventing the problem of caustic liquid leakage caused by loose connection, and ensuring the smooth progress of the subsequent electrolysis process. At the same time, bolt holes are also provided on the flange plate 3 for placing bolts to further fix the connection between the sub-pipeline 2 of the liquid inlet and the electrolytic cell.

[0033] Combined with Figure 2 shown, a sealing line 31 is provided on the flange plate 3 to ensure good sealing performance at the connection between the electrolytic cell liquid inlet and the sub-pipeline of the liquid inlet 2, preventing the leakage of caustic liquid, and thus ensuring the smooth progress of the electrolysis process. At the same time, in order to enhance the sealing effect, the number of sealing lines 31 provided on the flange plate 3 is not less than 3. In addition, both the main pipeline 1 of the liquid inlet and the sub-pipeline 2 of the liquid inlet are made of stainless steel material, which can ensure the corrosion resistance and strength of the pipeline.

[0034] Combined with Figure 1 and Figure 2 shown, after adopting the pipeline joint of the electrolytic cell liquid inlet of the present utility model, the caustic liquid flow process is as follows: when the caustic liquid flows in through the external pipeline, it first passes through the main pipeline 1 of the liquid inlet, and then is divided by the sub-pipeline 2 of the liquid inlet and evenly flows into the electrolytic cell compartments.

[0035] Combined with Figure 1 and Figure 2As shown in the figure, the present utility model proposes an electrolytic cell inlet pipeline joint. By arranging a plurality of inlet sub-pipelines 2 on the main inlet pipeline 1, the alkali liquor is evenly distributed into the electrolytic cell compartments through one-time shunting, improving the uniformity and efficiency of alkali liquor distribution. At the same time, the electrolytic cell inlet pipeline joint is more compact in structural design, reducing space occupation; the inlet sub-pipeline 2 adopts a modular design, and the inlet part 21 and the outlet part 22 of the sub-pipeline are connected through an elbow 23, improving the convenience of installation and disassembly of the inlet sub-pipeline 2. If a local problem occurs in the inlet sub-pipeline 2 and needs to be repaired or replaced, the problematic pipeline can be flexibly replaced individually without the need for overall replacement, thus saving a certain amount of economic cost; the overall structure of the electrolytic cell inlet pipeline joint provided by the present utility model is simple and compact, and the later maintenance is convenient; by adopting the above pipeline joint at the inlet of the electrolytic cell, while ensuring the electrolysis efficiency, the safety and maintenance convenience of the electrolytic cell can be significantly improved, providing a strong guarantee for the stable operation of the electrolytic cell.

[0036] Of course, the above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any equivalent structural transformation made by using the description and drawings of the present utility model under the inventive concept of the present utility model, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model and should be protected by the present utility model.
