Description

Technical Field

[0001] This utility model relates to a production device based on the process of producing hydrogen electrolyte through water electrolysis, and belongs to the technical field of electrolyte production devices. Background Technology

[0002] Electrolysis of water to produce hydrogen is a technology that converts electrical energy into chemical energy. Through an electrochemical reaction in an electrolyzer, water is decomposed into hydrogen and oxygen. This process is of great significance in energy conversion and storage, especially in the field of renewable energy. The electrolyte used in the electrolysis of water to produce hydrogen is mainly an alkaline solution, such as aqueous solutions of KOH and NaOH. When a direct current is passed through these alkaline solutions in the electrolyzer, water molecules undergo an electrochemical reaction at the electrodes, decomposing into hydrogen and oxygen.

[0003] In the production process of alkaline electrolytes, alkaline materials are mixed with pure water. The dissolution of sodium hydroxide releases a large amount of heat. If the solution is not cooled in time, the high temperature may accelerate the side reactions between sodium hydroxide and impurities in the water (such as calcium and magnesium ions), leading to turbidity or precipitation and affecting the purity of the electrolyte.

A second diversion pipe is fixedly connected to the left side of the second branch pipe, and a first diversion pipe is fixedly connected to the right side of the first branch pipe.

[0008] Preferably, the solution cooling mechanism further includes a coolant storage tank and a pump, wherein the coolant storage tank is fixedly installed on the top of the workbench, and the pump is fixedly installed on the top of the workbench and located in front of the coolant storage tank.

[0026] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the following detailed description, many specific details are set forth to facilitate explanation and provide a comprehensive understanding of the embodiments of the present invention. However, one or more embodiments may be practiced by those skilled in the art without these specific details.

[0027] like Figures 1-6 As shown, a production apparatus based on the process of producing hydrogen electrolyte by electrolysis of water includes a workbench 1, a preparation tank 11 fixedly installed on the top of the workbench 1, a discharge valve 12 fixedly connected to the bottom of the workbench 1, a solution cooling mechanism 2 provided on the workbench 1 and the preparation tank 11, and a solution mixing mechanism 3 provided on the top of the workbench 1.

[0028] In this embodiment, the solution cooling mechanism 2 includes a first branch pipe 24 and a second branch pipe 25. The first branch pipe 24 is fixedly installed on the right side of the preparation tank 11, and the second branch pipe 25 is fixedly installed on the left side of the preparation tank 11. An annular copper ring 28 is fixedly connected between adjacent sides of the first branch pipe 24 and the second branch pipe 25. Heat exchange fins 281 are fixedly connected to both the inner and outer surfaces of the annular copper ring 28. A second diversion pipe 26 is fixedly connected to the left side of the second branch pipe 25, and a first diversion pipe 23 is fixedly connected to the right side of the first branch pipe 24. The solution cooling mechanism 2 also includes a coolant storage tank 21 and a pump 22. The coolant storage tank 21 is fixedly installed on the top of the workbench 1, and the pump 22 is fixedly installed on the top of the workbench 1 and located in front of the coolant storage tank 21. The input pipe of the pump 22 is fixedly connected to the front of the coolant storage tank 21, and the output pipe of the pump 22 is connected to the first diversion pipe 23. The back of the second branch pipe 26 is fixedly connected to the back of the second branch pipe 26, and the return pipe 27 is fixedly connected to the left side of the coolant storage tank 21. During the preparation of electrolyte inside the preparation tank 11, the pump 22 is controlled to work and can draw coolant from inside the coolant storage tank 21. Through the design of the first branch pipe 23, the first branch pipe 24, the second branch pipe 25, the second branch pipe 26 and the return pipe 27, the coolant can flow back to the inside of the coolant storage tank 21 through the inner cavity of the annular copper ring 28, realizing the function of coolant circulation. During this process, the coolant will exchange heat with the solution inside the preparation tank 11 through the annular copper ring 28 to reduce the temperature of the solution and avoid the problem that the high temperature of the solution cannot be cooled in time, which will cause precipitation and affect the quality of the produced electrolyte. Through the design of the heat exchange fins 281, the overall heat exchange rate of the annular copper ring 28 can be improved.

[0029] In this embodiment, a flow guide baffle 211 is fixedly installed on the inner wall of the coolant storage tank 21. A straight copper pipe 212 is fixedly connected between the two sides of the inner wall of the coolant storage tank 21. A connecting cover 213 is fixedly connected to the right side of the coolant storage tank 21, and a cooling fan 214 is fixedly connected to the right side of the connecting cover 213. Both sides of the coolant storage tank 21 have round holes corresponding to the inner cavity of the straight copper pipe 212 to facilitate the passage of cooling air. During the operation of the pump 22, the cooling fan 214 is controlled to work simultaneously, and cooling air is delivered to the inside of the straight copper pipe 212 through the connecting cover 213 to dissipate heat from the coolant circulating inside the coolant storage tank 21, ensuring the cooling effect of the coolant on the solution inside the preparation tank 11. Through the design of the flow guide baffle 211, the coolant entering the coolant storage tank 21 in the return pipe 27 can be guided, so that the coolant can fully contact the outer wall of the straight copper pipe 212, improving the heat dissipation effect.

[0030] In this embodiment, the solution mixing mechanism 3 includes a column 31, which is fixedly installed on the top of the workbench 1. A horizontal plate 32 is fixedly installed on the front of the column 31, and a drive motor 33 is fixedly installed on the top of the horizontal plate 32. The output shaft of the drive motor 33 extends to the bottom of the horizontal plate 32 and is fixedly connected to an extension shaft 34. A stirring paddle 35 is fixedly installed on the outer wall of the extension shaft 34. The drive motor 33 is an existing slow-speed motor. By controlling the operation of the drive motor 33, the stirring paddle 35 can be driven to rotate slowly through the extension shaft 34 to perform small-amplitude stirring of the solution inside the preparation tank 11. This facilitates the dissolution of alkaline materials into the water. When sodium hydroxide dissolves, it releases a large amount of heat. This avoids the problem that rapid and uneven stirring can easily lead to a sharp increase in local temperature, causing the solution to boil or splash, resulting in the risk of burns, thus increasing safety.

[0031] In this embodiment, a bracket 36 is fixedly installed on the top of the column 31, a temporary storage cylinder 361 is fixedly installed on the inner wall of the bracket 36, a vibration motor 362 is fixedly installed on the outer wall of the temporary storage cylinder 361, and a branch tube 363 is fixedly connected to the bottom of the temporary storage cylinder 361. Powdered alkaline material is added to the inside of the temporary storage cylinder 361 in advance, and the alkaline material is then dispersed and input into the preparation tank 11 through the branch tube 363. Sodium hydroxide releases a lot of heat when it dissolves. This design avoids the problem of boiling or splashing of the solution when sodium hydroxide is added at one time, and further increases safety. The vibration motor 362 is controlled to drive the branch tube 363 to vibrate through the temporary storage cylinder 361, which improves the smoothness of material discharge from the branch tube 363.

[0032] The working principle of the production device based on the electrolysis of water to produce hydrogen electrolyte is as follows: In use, a certain amount of water is first added to the inner cavity of the preparation tank 11. Then, the drive motor 33 is controlled to operate, driving the stirring paddle 35 to rotate slowly through the extension shaft 34, thus stirring the solution inside the preparation tank 11 slightly. Next, a certain amount of powdered alkaline material is added to the interior of the temporary storage cylinder 361 in multiple batches. The alkaline material is then dispersed into the preparation tank 11 through the branch capillary tube 363. When the pH value inside the preparation tank 11 is approximately 10, the preparation is complete. During this process, the pump 22 is controlled to operate, drawing coolant from the storage tank 21. The coolant in the preparation tank 11 is circulated back through the inner cavity of the annular copper ring 28 to the interior of the coolant storage tank 21, thus achieving the function of coolant circulation. The coolant exchanges heat with the solution inside the preparation tank 11 through the annular copper ring 28, reducing the temperature of the solution. At the same time, the cooling fan 214 is controlled to work, delivering cooling air through the connecting cover 213 into the interior of the straight copper pipe 212 to dissipate heat from the coolant circulating inside the coolant storage tank 21, ensuring the cooling effect of the coolant on the solution inside the preparation tank 11. After the preparation is completed, the bottom of the discharge valve 12 can be connected to an external hose, and the discharge valve 12 can be opened to discharge the alkaline electrolyte for use.

It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
