BACKGROUND

[0002] In the electrolytic industry, electrolytic cell is the core equipment of electrolytic process, in which anode plate and cathode plate undergo electrochemical reaction through electrolyte to produce the required chemical products. The traditional electrolytic cell power supply system usually adopts single power supply loop, i.e. the anode conductive main plate and the cathode conductive main plate directly provide power for the anode plate and the cathode plate. However, this single power supply loop has obvious limitations. In actual operation, due to the poor electrical contact between the anode plate or the cathode plate and the conductive main plate caused by various reasons (such as corrosion, wear, improper installation, etc.), the electrolytic cell may have partial or overall power supply problems, which further affects the electrolytic efficiency and may even cause interruption of the electrolytic process.

[0003] In order to overcome this problem, various methods have been tried in the industry, such as strengthening the maintenance of electrical contact points and improving the performance of conductive materials, but these methods can only alleviate the problem to a certain extent and cannot fundamentally solve the power supply stability problem caused by poor electrical contact. In addition, with the expansion of the scale of electrolytic cell and the improvement of electrolytic efficiency, higher requirements are put forward for the stability and reliability of the power supply system.

[0004] Therefore, there is an urgent need for a power supply device that can ensure stable power supply of anode plate and cathode plate in electrolytic cell under any circumstances. The utility model is proposed based on this demand, by designing a multi-loop power supply device with a main power supply loop and a secondary power supply loop, when any electrical contact point in the main power supply loop appears poor contact, the secondary power supply loop can quickly take over the power supply task, thereby ensuring the continuity and stability of the electrolytic process. This design not only improves the electrolytic efficiency, but also greatly reduces the risk of electrolytic process interruption caused by poor electrical contact. CONTENT OF THE UTILITY MODEL

In the case of no conflict, the features in the following examples can be combined with each other.

[0041] Example one

[0042] The embodiment provides a kind of multi-loop power supply device of electrolytic system, its structure is as shown in Figures 1-11 The device mainly includes main power supply loop and vice power supply loop, for providing stable power supply for anode plate and cathode plate in electrolytic cell.

[0043] As shown in Figures 3-7 Main power supply loop is composed of anode conductive main plate 2 and cathode conductive main plate 3. The two conductive main plates are spaced apart in the width direction of electrolytic cell 1, to ensure that anode plate 10 in electrolytic cell and anode conductive main plate 2 are in good electrical contact, while cathode plate 11 and cathode conductive main plate 3 are in good electrical contact, to form a stable current path. Specifically, when anode conductive main plate 2, anode plate 10, electrolyte, cathode plate 11 and cathode conductive main plate 3 are connected in turn, a main power supply loop is formed.

[0044] Vice power supply loop is composed of anode conductive vice plate 4 and cathode conductive vice plate 5. The two conductive vice plates are also spaced apart in the width direction of electrolytic cell 1. When any anode plate 10 in main power supply loop and anode conductive main plate 2 are in poor electrical contact, or any cathode plate 11 and cathode conductive main plate 3 are in poor electrical contact, the corresponding anode plate 10 or cathode plate 11 will be converted to be powered by the corresponding anode conductive vice plate 4 or cathode conductive vice plate 5, to ensure the continuity of electrolysis process.

[0045] Anode conductive main plate 2 and anode conductive vice plate 4 are spaced apart in the width direction of electrolytic cell 1, as shown in Figure 1The anode conductive main plate 2 is configured to electrically contact one conductive end of the anode plate 10, and the anode conductive auxiliary plate 4 is configured to electrically contact another conductive end of the anode plate 10. This configuration ensures that when the electrical contact point in the main power supply circuit is poor, the auxiliary power supply circuit can quickly take over the power supply task, thereby ensuring the stable operation of the electrolytic cell.

[0046] The cathode conductive main plate 3 and the cathode conductive auxiliary plate 5 are also spaced apart in the width direction of the electrolytic cell 1, as shown in Figure 1 The cathode conductive main plate 3 is configured to electrically contact one conductive end of the cathode plate 11, and the cathode conductive auxiliary plate 5 is configured to electrically contact another conductive end of the cathode plate 11. This configuration ensures that the auxiliary power supply circuit can take over the power supply task in time when the main power supply circuit is poor in electrical contact, thereby maintaining the normal operation of the electrolytic cell.

[0047] In order to ensure the safety and reliability of the power supply system, the embodiment also adopts an insulation design and a flexible insulation pad.

[0048] The anode conductive main plate 2 and the cathode conductive auxiliary plate 5 are arranged on the same side of the electrolytic cell 1, and the cathode conductive auxiliary plate 5 is arranged above the anode conductive main plate 2, as shown in Figure 6 and Figure 7 In order to prevent electrical short circuit between them, a first insulation piece 6 is arranged between the anode conductive main plate 2 and the cathode conductive auxiliary plate 5. The cathode conductive auxiliary plate 5 is embedded in the groove in the first insulation piece 6, achieving effective electrical isolation. The first insulation piece 6 can be made of epoxy resin insulation material or other insulation materials to ensure its insulation performance and corrosion resistance.

[0049] A first flexible insulation pad 8 is arranged between the anode conductive main plate 2 and the cell rim of the electrolytic cell 1, as shown in Figure 6 and Figure 7 The first flexible insulation pad 8 not only provides electrical isolation, but also absorbs stress caused by temperature changes or mechanical vibrations, thereby protecting the anode conductive main plate 2 from damage. The first flexible insulation pad 8 can be made of rubber material or other flexible insulation materials to ensure that it has good elasticity and insulation performance.

[0050] Similarly, the cathode conductive main plate 3 and the anode conductive auxiliary plate 5 can also be arranged on the same side of the electrolytic cell 1, and the anode conductive auxiliary plate 5 is arranged above the cathode conductive main plate 3. At this time, a second insulation piece 7 needs to be arranged between the cathode conductive main plate 3 and the anode conductive auxiliary plate 5 to ensure electrical isolation between them. The anode conductive auxiliary plate 5 is embedded in the groove in the second insulation piece 7, as shown in Figure 8 and Figure 9

[0051] A second flexible insulation pad 9 is arranged between the cathode conductive main plate 3 and the cell rim of the electrolytic cell 1, as​Figure 8 and Figure 9 The second flexible insulating pad 9 can also be made of rubber or other flexible insulating material, ensuring good elasticity and insulation performance.

[0052] The embodiment also provides an electrolysis system having the above-mentioned multi-loop power supply device, which has the structure as shown in Figure 1 and Figure 2 The electrolysis system includes a plurality of electrolytic tanks connected in series, including at least two side tanks (an entry side tank 101 and an exit side tank 102) and at least one intermediate tank 103 arranged between the side tanks.

[0053] The entry side tank 101 arranged at the current entry side is provided with an anode conductive main plate 2 and a cathode conductive auxiliary plate 5 on its outer edge away from the intermediate tank 103, as shown in Figure 6 and Figure 7 The anode conductive main plate 2 is directly electrically connected to the positive pole of the power supply, thereby providing power input for the entire electrolysis system. In addition, the entry side tank 101 is also provided with a cathode conductive main plate 3 and an anode conductive auxiliary plate 4 on its inner edge close to the intermediate tank 103, to ensure stable power supply between adjacent intermediate tanks 103.

[0054] The intermediate tank 103 close to the entry side tank 101 is provided with an anode conductive main plate 2 and a cathode conductive auxiliary plate 5 on its edge close to the side tank, as shown in Figure 10 and Figure 11 In order to improve the power supply efficiency and stability, the anode conductive main plate 2 and the cathode conductive auxiliary plate 5 can be integrally arranged. Further, the anode conductive main plate 2 arranged on the intermediate tank 103 and the cathode conductive main plate 3 arranged on the adjacent electrolytic tank are also integrally arranged. This arrangement simplifies the power supply structure, reduces the number of electrical contact points, and thus reduces the risk of power supply interruption caused by poor electrical contact.

[0055] Meanwhile, the anode conductive auxiliary plate 4 arranged on the intermediate tank 103 and the cathode conductive auxiliary plate 5 arranged on the adjacent electrolytic tank are separately arranged, as shown in Figure 10 and Figure 11 This separate arrangement facilitates quick switching to the auxiliary power supply loop when needed, ensuring the continuity of the electrolysis process.

[0056] The exit side tank 102 arranged at the current exit side is provided with a cathode conductive main plate 3 and an anode conductive auxiliary plate 4 on its outer edge away from the intermediate tank 103, as shown in Figure 8 and Figure 9The cathode conductive main plate 3 is directly connected to the negative pole of the power supply, thereby providing power output for the entire electrolysis system. Similarly, the out-side side tank 102 can also be configured with additional anode conductive sub-plate 4 and cathode conductive sub-plate 5 (see Figure 4 as shown) on its inner edge close to the intermediate tank 103, to further balance the current distribution and improve the stability of power supply.

[0057] Embodiment Two

[0058] The present embodiment provides a multi-loop power supply device for an electrolysis system and an electrolysis system thereof, which is further optimized and improved on the basis of Embodiment One.

[0059] Specifically, the electrolysis system includes two electrolysis tanks connected in series, namely a first electrolysis tank and a second electrolysis tank, without an intermediate tank (see Figure 1 as shown, with the intermediate tank part removed). The inter-tank multi-loop conductive device between the two electrolysis tanks adopts the power supply device as in Figure 10 and 11 The anode multi-loop conductive device adopts the side tank conductive device as in Figure 6 and Figure 7 The cathode multi-loop conductive device adopts the side tank conductive device as in Figure 8 and Figure 9 The anode conductive main plate and the cathode conductive main plate are connected as one body, with the left part being the cathode conductive main plate and the right part being the anode conductive main plate. The cathode conductive sub-plate is configured above the anode conductive main plate, and the anode conductive sub-plate is configured above the cathode conductive main plate. This staggered connection helps to reduce the resistance and inductance on the current path, thereby improving the electrolysis efficiency. At the same time, the cathode conductive sub-plate configured on the first electrolysis tank and the anode conductive sub-plate 5 configured on the second electrolysis tank are still set separately, so as to quickly switch to the sub-power supply loop when needed.

[0060] In another embodiment, the anode conductive main plate and the cathode conductive main plate can also be set separately.

[0061] In the present embodiment, the first electrolysis tank is directly connected to the positive pole of the power supply, and the second electrolysis tank is connected to the negative pole of the power supply.

[0062] In order to further improve the insulation performance and reliability, the present embodiment selects an insulating material with higher insulation strength and temperature resistance to make the first insulating part and the second insulating part. These insulating materials can maintain stable insulation performance in harsh electrolysis environment, thereby prolonging the service life of the power supply device.

[0063] The flexible insulation pad is not only more elastic and wear-resistant, but also maintains stable insulation performance in a wider temperature range. In addition, the shape and size of the flexible insulation pad are precisely designed to ensure close fitting between the electrolytic cell rim and the conductive plate, thereby improving the insulation effect.

[0064] Due to the optimization and improvement of the embodiment based on embodiment one, the power supply stability and electrolysis efficiency are higher. The optimized configuration of the anode conductive main plate, the anode conductive auxiliary plate, the cathode conductive main plate and the cathode conductive auxiliary plate helps to balance the current distribution and improve the electrolysis efficiency. The optimized selection of the insulation material and the flexible insulation pad further improves the reliability and safety of the power supply system. These optimizations and improvements make the multi-loop power supply device and the electrolysis system of the embodiment more suitable for electrolytic cells of various scales and have strong adaptability and flexibility.

[0065] As can be seen from the above description, the multi-loop power supply device and the electrolysis system of the embodiment are further optimized and improved based on embodiment one, with higher power supply stability and electrolysis efficiency. The device is not only suitable for electrolytic cells of various scales, but also can maintain stable operation in harsh electrolysis environment, thereby improving the production efficiency and capacity of the entire electrolysis system.

[0066] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
