Description

Technical Field

[0001] This utility model relates to the field of activation spraying technology, and in particular to an integrated equipment for Raney nickel activation spraying for hydrogen production by water electrolysis. Background Technology

[0002] Electrolysis of water to produce hydrogen is a process that uses electrolysis to decompose water into hydrogen and oxygen. This process is typically carried out in an electrolytic cell, where direct current is passed through water, causing water molecules to undergo oxidation and reduction reactions at the anode and cathode, respectively, to produce oxygen and hydrogen. This method produces high-purity hydrogen and does not generate greenhouse gases, making it a clean hydrogen production method. However, common hydrogen production methods often require the application of Raney nickel. Raney nickel activation spraying is a highly efficient electrode preparation technology for water electrolysis to produce hydrogen. Raney nickel is a porous nickel-aluminum alloy. After aluminum removal through alkali treatment, a high specific surface area nickel framework is formed, exhibiting excellent catalytic activity. In water electrolysis to produce hydrogen, Raney nickel, as the cathode material, can significantly reduce the overpotential of the hydrogen evolution reaction and improve hydrogen production efficiency. Uniformly coating the electrode substrate with Raney nickel using spraying technology can further enhance its conductivity and stability, but the activation process requires the replenishment of activation solution.

[0003] Existing electrolyte replenishment systems typically include storage tanks, pumps, pipelines, and flow control systems. These systems can adjust the flow rate and concentration of the electrolyte in real time according to the operating status of the electrolyzer, ensuring that the electrode surface is always under optimal reaction conditions. The main function of the replenishment system is to continuously supply electrolyte to the electrolyzer to maintain the electrolysis reaction. The design of the replenishment system needs to consider corrosion resistance and sealing performance to adapt to strongly alkaline environments. Through automated control, the replenishment system can achieve precise liquid replenishment, avoiding the impact of excessive or insufficient electrolyte on electrode performance and hydrogen production efficiency. In addition, the replenishment system can be integrated with the electrolyzer's thermal management system to regulate the electrolyte temperature and further optimize the hydrogen production process. However, this replenishment method requires manual addition, which cannot accurately control the dosage, resulting in waste and increased production costs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an integrated Raney nickel activation and spraying equipment for hydrogen production by water electrolysis, which aims to improve the problem that the existing technology requires manual addition of liquid, which makes it impossible to accurately control the dosage, resulting in waste and increased production costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an integrated Raney nickel activation spraying device for hydrogen production by water electrolysis, comprising a housing, a drive frame fixedly connected to the rear end of the inner wall of the housing, multiple circular holes on the outer wall of the drive frame, a perforated bottom plate fixedly connected to the bottom of the drive frame, a sphere slidably connected to the top of the perforated bottom plate, a conical cylinder slidably connected to the top of the sphere, a connecting cylinder II connected near the middle of the top of the conical cylinder, a storage tank connected to the top of the connecting cylinder II, a side baffle fixedly connected to the rear end of the inner wall of the storage tank, a heating tube fixedly connected to the rear end of the side baffle, a discharge pipe connected to the front side of the housing, the rear end of the heating tube fixedly connected to the rear end of the inner wall of the storage tank, and a replacement mechanism provided on the front side of the housing for replacement and disassembly.

A square groove and an elongated groove are formed on the outer wall of the connecting cylinder. A connecting rod is fixedly connected inside the elongated groove. A spring is slidably connected to the outer wall of the connecting rod. A square stop is fixedly connected to the front side of the spring. A sliding column is fixedly connected to the top of the square stop. A fixed column is fixedly connected to the top of the front side of the outer wall of the discharge pipe.

[0008] As a further description of the above technical solution:

[0009] The top of the liquid storage tank is connected to a feed pipe, and the top of the feed pipe is connected to a feed inlet.

[0010] As a further description of the above technical solution:

[0011] The bottom of each box is fixedly connected to multiple connecting columns, and the bottom of each connecting column is fixedly connected to a fixing plate.

[0012] As a further description of the above technical solution:

[0013] A motor is fixedly connected to the top of the fixed plate, and a stirring blade is fixedly connected to the top of the motor. The bottom of the stirring blade is slidably connected to the bottom of the inner wall of the box.

[0014] As a further description of the above technical solution:

[0015] A nozzle is fixedly connected to the front side of the connecting cylinder, a filter screen is fixedly connected inside the nozzle, and a valve is rotatably connected inside the discharge pipe.

[0016] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the activation liquid first enters the feed pipe through the feed inlet, and then enters the storage tank through the feed pipe. At this time, it is stored in the storage tank, and then heated by the heating pipe in the storage tank. At this time, the liquid flows into the interior of the tank through the connecting cylinder and the conical cylinder, and the liquid in the tank increases. The liquid enters the interior of the drive frame through the circular hole, and then the ball is lifted up until the ball blocks the opening of the conical cylinder. At this time, the liquid can no longer flow down, thus realizing the function of heating the incoming activation liquid to improve its activity while achieving automatic addition.

[0022] 2. In this utility model, when the nozzle is worn, the sliding column is first pulled backward, which then drives the square stop block to move backward and compresses the spring. At this time, the nozzle will be squeezed on the connecting rod and pushed backward. This will drive the connecting cylinder to move backward, and then the fixing column will slide on the long groove until it rotates out. At this time, the nozzle can be removed and a new nozzle can be installed. This realizes the function of quickly disassembling and replacing the nozzle when it is worn. Attached Figure Description

[0041] Working principle: First, the activation liquid enters the feed pipe 12 through the feed inlet 13, and then enters the storage tank 9 through the feed pipe 12. At this time, it is stored in the storage tank 9. Then, it is heated by the heating pipe 10 in the storage tank 9. At this time, the liquid flows into the interior of the box 1 through the connecting cylinder 8 and the conical cylinder 7. At this time, the liquid in the box 1 increases. The liquid enters the interior of the drive frame 3 through the circular hole 4. At this time, the ball 6 is lifted up until the ball 6 blocks the opening of the conical cylinder 7. At this time, the liquid can no longer flow downward. When the liquid is too low, the ball 6 moves downward. At this time, the conical cylinder 7 opens, and the liquid enters the box 1. This realizes the function of heating the incoming activation liquid to improve its activity while achieving automatic replenishment.

[0042] When the nozzle 18 wears out, first pull the sliding column 207 backward. Then, the sliding column 207 drives the square stop block 206 to move backward, while simultaneously compressing the spring 205. At this time, the spring 205 will be compressed on the connecting rod 204, pushing the nozzle 18 backward. The nozzle 18 will then drive the connecting cylinder 201 to move backward, causing the fixing column 208 to slide on the long groove 203 until it rotates out. At this point, the nozzle 18 can be removed, and a new nozzle 18 can be installed. Then, turning the valve 20 will spray, thus achieving the function of quickly disassembling and replacing the nozzle 18 when it wears out.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
