Description

TECHNICAL FIELD

[0001] The utility model relates to an electrolytic equipment, concretely relates to a sodium chlorate electrolytic cell. BACKGROUND

[0002] In the prior art field of sodium chlorate electrolytic cell, there are some significant technical problems, which not only affect the working efficiency of the electrolytic cell, but also increase the production cost and maintenance difficulty.

[0003] Firstly, from the structure, the spacing between the cathode and the anode in the prior art sodium chlorate electrolytic cell is relatively large. Although this design can reduce the risk of short circuit in the electrolysis process to some extent, it also brings the problem of low electrolysis efficiency. Because the increase of the spacing between the cathode and the anode means the increase of the transmission path of the electrolyte between the two poles, the resistance is increased, which leads to the increase of energy consumption and the decrease of electrolysis efficiency. In addition, the large spacing may also cause uneven distribution of current in the electrolytic cell, further affecting the electrolysis effect.

[0004] Secondly, in the selection and use of cathode material, the prior art also faces challenges. Many sodium chlorate electrolytic cells use cathode materials with relatively short service life, which are prone to corrosion or wear during electrolysis, resulting in the need to frequently replace the cathode rod, which not only increases the production cost, but also affects the continuous and stable operation of the electrolytic cell. More seriously, some cathode materials are prone to bubbling during electrolysis, which is due to the expansion of the pores or impurities in the material by the gas generated during electrolysis, causing deformation of the cathode surface, and thus affecting the electrolysis effect. This bubbling phenomenon not only reduces the effective working area of the cathode, but also may cause short circuit or leakage in the electrolytic cell, etc.

[0005] In summary, the prior art sodium chlorate electrolytic cell has obvious deficiencies in structure and cathode material, which need to be solved through technical innovation. Therefore, it is of great significance to develop a sodium chlorate electrolytic cell with smaller spacing between cathode and anode, higher service life of cathode material and less bubbling, in order to improve the electrolysis efficiency, reduce the production cost and ensure the safe and stable operation of the electrolytic cell. SUMMARY

[0006] The utility model aims at providing a sodium chlorate electrolytic cell to solve the problems of easy short circuit, low service life of cathode material and easy bubbling in the prior art.

[0007] In order to achieve the above purpose of the utility model, an embodiment of the utility model provides a sodium chlorate electrolytic cell, which comprises:

[0008] The electrolytic cell has two opposite side walls.

[0009] The cathode conductive rod and the anode conductive rod are symmetrically arranged on the inner sides of the two side walls.

[0013] As a further improvement of an embodiment of the utility model, the cathode rod is an iron alloy structure, and the content of iron is 99.50%-99.90%.

[0016] As a further improvement of an embodiment of the utility model, the electrolytic accommodation groove comprises a groove body with an accommodation cavity and a cover body, the upper end of the groove body is provided with an opening communicating with the accommodation cavity, and the cover body is connected with the groove body to cover the opening.

[0017] As a further improvement of an embodiment of the utility model, the sodium chlorate electrolytic cell further comprises an insulating member, and the cathode conductive rod and the anode conductive rod are connected with the two side walls through the insulating member respectively.

[0018] Compared with the prior art, the utility model has the beneficial effects that:

[0019] This invention reduces the electrode spacing between the cathode and anode by adjusting the arrangement of multiple cathode and anode rods and the distance between any two adjacent cathode and anode rods.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0034] In the utility model, in the case that no opposite statement is made, the orientation words such as '' upper, lower, top, bottom '' used are usually for the direction shown in the drawing or for the vertical, perpendicular or gravity direction of the components themselves; similarly, for the convenience of understanding and description, '' inner, outer '' refers to the inner and outer of the contour of each component itself, but the above orientation words are not used to limit the utility model.

[0035] In order to solve the problems of easy short circuit, low service life of cathode material and easy bubbling of sodium chlorate electrolytic cell in the prior art, the utility model provides a new sodium chlorate electrolytic cell.

[0036] The utility model will be further explained in detail in combination with the drawings and specific embodiments.

[0037] As Figures 1-4 shown, an embodiment of the utility model provides a sodium chlorate electrolytic cell, which comprises:

[0038] An electrolytic containing tank 1 is used for containing electrolyte and has two opposite side walls;

[0039] A cathode conductive rod 2 and an anode conductive rod 3 are symmetrically arranged on the inner sides of the two side walls and used for transmitting current to cathode rods 4 and anode rods 5 respectively;

[0040] A plurality of cathode rods 4 and a plurality of anode rods 5 are arranged in the electrolytic containing tank 1, the plurality of cathode rods 4 and the plurality of anode rods 5 are all arranged horizontally and fixedly connected with the cathode conductive rod 2 and the anode conductive rod 3 in an electrically connected manner.

[0041] Further, the plurality of cathode rods 4 and the plurality of anode rods 5 are configured to be spaced apart along the axial direction of the cathode conductive rod 2 and alternately arranged, forming an alternating arrangement mode of cathode and anode.

[0042] Further, as shown in the drawing, Figure 4 The distance d between any adjacent one cathode rod 4 and one anode rod 5 is accurately controlled to be 2.5-3mm, so as to optimize the electrolysis efficiency and reduce the energy consumption.

[0043] By arranging the cathode rods 4 and the anode rods 5 in the above mode, the inter-electrode distance between the cathode and the anode can be reduced, so that the cell voltage can be effectively reduced and the energy consumption in the electrolysis process can be reduced. This improvement not only improves the electrolysis efficiency, but also enables the electrolytic cell to process more sodium chlorate under the same conditions, thereby improving the production capacity.

[0044] Further, as shown in the drawing, Figure 3As shown, one end of the anode rod 5 is tightly connected to the anode conducting rod 3, ensuring stable transmission of current, while the other end extends towards the direction of the cathode conducting rod 2, but maintains a certain interval distance from the cathode conducting rod 2 to avoid short circuit caused by direct contact.

[0045] Similarly, one end of the cathode rod 4 is also firmly connected to the cathode conducting rod 2, and the other end extends towards the anode conducting rod 3 and maintains a corresponding interval distance from the anode conducting rod 3. This design not only ensures the smooth progress of the electrolysis process, but also further optimizes the electrolysis efficiency by precisely controlling the interval distance between the anode and cathode, ensuring the stable operation of the electrolytic cell.

[0046] Preferably, in order to further optimize the balance between electrolysis efficiency and energy consumption, the interval distance between any adjacent one of the cathode rod 4 and one of the anode rod 5 is finely adjusted to the range of 2.6-2.8mm. This fine tuning not only ensures the uniformity of current distribution during electrolysis, reduces energy loss caused by excessive or insufficient interval distance, but also further improves the overall stability and reliability of the electrolytic cell, providing a strong guarantee for long-term efficient operation.

[0047] Further, in order to solve the problem of bubbling of the cathode rod 4 during use, the utility model particularly adopts a cathode rod 4 made of ferrous alloy.

[0048] Specifically, in the cathode rod 4 of the ferrous alloy structure, the content of iron is precisely controlled between 99.50% and 99.90%, which not only ensures that the cathode rod 4 has good electrical conductivity and mechanical strength, but also effectively improves its corrosion resistance and high temperature resistance, thereby significantly reducing the occurrence of bubbling, prolonging the service life of the cathode rod 4, and ensuring the long-term stable operation of the electrolytic cell.

[0049] The cathode conducting rod 2 and the anode conducting rod 3 are stably arranged along the horizontal direction, which not only facilitates stable connection with the side wall of the electrolytic container 1, but also ensures uniform transmission of current in the horizontal direction to each cathode rod 4 and anode rod 5. At the same time, the horizontally arranged conducting rod helps to reduce the deformation caused by gravity, improves the overall structural stability and service life of the electrolytic cell, and provides reliable guarantee for the continuity and stability of the electrolysis process.

[0050] Further, the plurality of cathode rods 4 are precisely and evenly spaced along the axial direction of the cathode conductive rod 2, and similarly, the plurality of anode rods 5 are also evenly spaced along the axial direction of the anode conductive rod 3 (i.e. the axial direction of the cathode conductive rod 2). Such a layout design not only ensures that each cathode rod 4 and anode rod 5 can obtain equal current distribution, avoiding the problem of local overheating or excessive current density, but also further improves the overall electrolysis efficiency of the electrolytic cell, providing strong support for efficient electrolysis of sodium chlorate.

[0051] In the utility model, reference Figures 1-3 As shown in the figure, the electrolytic accommodation groove 1 is mainly composed of a groove body 11 with a spacious accommodation cavity and a cover body 12 matched therewith. The upper end of the groove body 11 is designed with an opening communicated with the accommodation cavity, facilitating the injection and discharge of electrolyte. The cover body 12 is tightly connected to the upper end of the groove body 11, effectively covering the opening, preventing the splashing of electrolyte and ensuring the closed nature of the electrolysis process, providing a solid guarantee for the safe and stable operation of the electrolytic cell.

[0052] Further, the sodium chlorate electrolytic cell also ingeniously incorporates the design of insulating pieces, which play a crucial role in isolation. The cathode conductive rod 2 and the anode conductive rod 3 are both stably and safely connected to the two side walls of the electrolytic accommodation groove 1 through these insulating pieces. The application of insulating pieces effectively prevents direct leakage of current, ensuring the electrical safety of the electrolysis process, while also improving the overall stability and durability of the electrolytic cell, laying a solid foundation for long-term efficient operation.

[0053] In summary, the embodiments of the utility model realize the following technical effects:

[0054] First, through the careful design of the cathode rod and anode rod arrangement, the distance between the cathode and anode is successfully reduced. This setting not only significantly reduces the cell voltage, but also effectively reduces energy consumption during the electrolysis process. More importantly, it greatly improves the electrolysis efficiency, enabling the electrolytic cell to handle a larger amount of sodium chlorate raw material under the same conditions, thereby significantly improving the production capacity.

[0055] Second, the cathode adopts a new type of alloy material, significantly improving its service life, and at the same time solving the problem of easy bubbling and short circuit of traditional cathode materials.
