Description

Technical Field

[0001] This utility model relates to the field of hydrogen production technology, specifically a renewable energy electrolysis water hydrogen production device. Background Technology

[0002] With global energy resources facing depletion, water electrolysis is a relatively convenient method for producing hydrogen. By passing direct current through an electrolyzer filled with electrolyte, water molecules undergo an electrochemical reaction at the electrodes, decomposing into hydrogen and oxygen. This method not only avoids environmental pollution but also promotes the development of renewable energy.

[0003] However, in reality, traditional renewable energy water electrolysis hydrogen production equipment not only produces hydrogen with low purity, but also has low efficiency. Furthermore, traditional renewable energy water electrolysis hydrogen production equipment generates a large amount of heat during the hydrogen production process, which can easily damage the equipment and electrolyzer, resulting in low safety performance. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a renewable energy electrolysis water hydrogen production device.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This utility model provides a renewable energy electrolysis water hydrogen production device, including an electrolysis component, a separation component, a collection component, and a water cooling component. The electrolysis component is provided with an electrolysis cell, and a power supply is installed at the top center of the electrolysis cell. The separation component is located on one side of the electrolysis cell, and a first gas collecting tank is provided on the separation component. The collection component is located on one side of the first gas collecting tank. The water cooling component is located on the side of the electrolysis cell away from the separation component, and a water tank is provided on the water cooling component.

[0006] Preferably, a diaphragm is provided in the middle of the electrolytic cell, and an anode plate and a cathode plate are respectively provided at the bottom of the power supply. The anode plate and the cathode plate are respectively located on both sides of the diaphragm, with the anode plate close to the water cooling component and the cathode plate close to the separation component.

[0007] Preferably, the electrolytic cell has a rectangular parallelepiped structure, and a drain outlet is provided at the bottom of the side of the electrolytic cell near the water-cooling component, with a first water pump installed on the drain outlet.

[0008] Preferably, a first air outlet is provided at the top of the electrolytic cell near the power source, a first vent pipe is provided at the bottom of one side of the first gas collecting tank, one end of the first vent pipe is connected to the top of one side of the electrolytic cell, a dryer is provided on the first vent pipe near the electrolytic cell, a permeation membrane is provided in the middle of the electrolytic cell, a second air outlet is provided at the first gas collecting tank, and a first air outlet is provided at the top of the electrolytic cell near the power source.

[0009] Preferably, a second vent pipe is provided on the top of the second gas collecting tank, and the second vent pipe is located at the middle of the top of the first gas collecting tank, and the top of the first gas collecting tank has an arc-shaped structure.

[0010] Preferably, a water inlet is provided on one side of the water tank, and a water pipe is provided on the top of the water tank. One end of the water pipe is located at the bottom center of the inner wall of the water tank, and a second water pump is installed on the water pipe. One end of the second water pipe is connected to the top side of the electrolytic cell.

[0011] The beneficial effects of this utility model are:

[0012] (1) By turning on the power supply of the electrolysis assembly, oxygen is generated on the anode plate and hydrogen is generated on the cathode plate. The hydrogen generated on the cathode plate is dried by the dryer, which helps to remove the residual moisture in the hydrogen on the cathode plate. Since the density of oxygen is greater than that of hydrogen, the small amount of oxygen contained in the hydrogen is separated by the permeation membrane, which helps to produce purer hydrogen. Secondly, the pure hydrogen in the first gas collection tank enters the second gas collection tank through the second vent pipe on the collection assembly for storage. At the same time, the first gas outlet is opened on the electrolysis cell at the top of the anode plate and the second gas outlet is set at the bottom of the first gas collection tank, which helps to discharge the oxygen electrolyzed by the electrolysis assembly and improve air quality.

[0013] (2) By installing a water-cooling component on one side of the electrolyzer and turning on the second water pump on the water pipe, on the one hand, it not only saves the time of adding water to the electrolyzer by manpower, but also facilitates the continuous hydrogen production operation of the electrolyzer component, thereby improving the hydrogen production efficiency of the hydrogen production equipment. On the other hand, it is also beneficial to keep the electrolyzer in a closed space and avoid the entry of air gas into the electrolyzer, which may cause unnecessary impact on the collection of hydrogen. On the other hand, since a large amount of heat is generated when producing hydrogen by electrolyzing water, the water-cooling component is used to supply water to the electrolyzer to cool the electrolyzer and other equipment, remove excess heat, thereby control the working temperature of the electrolyzer, prevent the equipment from being damaged due to overheating, and further improve the safety of the hydrogen production equipment during use.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-5 As shown, this utility model discloses a renewable energy electrolysis water hydrogen production device, including an electrolysis component 1, a separation component 3, a collection component 4, and a water cooling component 5. The electrolysis component 1 is provided with an electrolysis cell 101, and a power supply 102 is installed at the top center of the electrolysis cell 101. The power supply 102 outputs direct current. The separation component 3 is located on one side of the electrolysis cell 101, and a first gas collecting tank 301 is provided on the separation component 3. The collection component 4 is located on one side of the first gas collecting tank 301. The water cooling component 5 is located on the side of the electrolysis cell 101 away from the separation component 3, and a water tank 501 is provided on the water cooling component 5. The water tank 501 is filled with pure water.

[0023] A diaphragm 103 is provided in the middle of the electrolytic cell 101 to effectively prevent oxygen generated by the anode plate 104 from mixing into the hydrogen in the cathode plate 105. An anode plate 104 and a cathode plate 105 are respectively provided at the bottom of the power supply 102. The anode plate 104 and the cathode plate 105 are respectively located on both sides of the diaphragm 103. The anode plate 104 is close to the water cooling component 5, and the cathode plate 105 is close to the separation component 3. By turning on the power supply 102 on the electrolytic component 1, oxygen is generated on the anode plate 104 and hydrogen is generated on the cathode plate 105.

[0024] The electrolytic cell 101 has a rectangular parallelepiped structure. A drain outlet 106 is provided at the bottom of one side of the electrolytic cell 101 near the water-cooling component 5. A first water pump 107 is provided on the drain outlet 106. By turning on the first water pump 107, it is beneficial to discharge the electrolyzed water in the electrolytic cell 101 through the drain outlet 106.

[0025] A first vent pipe 302 is installed at the bottom of one side of the first gas collecting tank 301. One end of the first vent pipe 302 is connected to the top of one side of the electrolytic cell 101. Pure hydrogen gas in the first gas collecting tank 301 enters the second gas collecting tank 401 for storage through the second vent pipe 402 on the collecting assembly 4. A dryer 303 is installed on the first vent pipe 302 near the electrolytic cell 101. Hydrogen gas generated on the cathode plate 105 is dried by the dryer 303, which helps to remove residual moisture from the hydrogen gas on the cathode plate 105. A permeation device is installed in the middle of the electrolytic cell 101. The permeable membrane 304 is designed to separate the small amount of oxygen contained in hydrogen gas, which is denser than hydrogen gas. This process helps to produce purer hydrogen gas. The first gas collecting tank 301 has a second gas outlet 305, and the top of the electrolytic cell 101 near the power source 102 has a first gas outlet 2. The first gas outlet 2 on the electrolytic cell 101 at the top of the anode plate 104 and the second gas outlet 305 at the bottom of the first gas collecting tank 301 facilitate the discharge of oxygen electrolyzed by the electrolysis component 1, thereby improving air quality.

[0026] The second gas collecting tank 401 is equipped with a second vent pipe 402 at its top. The second vent pipe 402 is located at the top center of the first gas collecting tank 301. The top of the first gas collecting tank 301 has an arc-shaped structure. A gas valve is provided on one side of the second gas collecting tank 401. The second vent pipe 402 is inserted into the bottom of the inner side of the second gas collecting tank 401 to discharge excess air from the second gas collecting tank 401. This facilitates the movement of hydrogen to the top of the inner wall of the first gas collecting tank 301 and allows pure hydrogen in the first gas collecting tank 301 to enter the second gas collecting tank 401 for storage via the second vent pipe 402 on the collecting assembly 4.

[0027] A water inlet 502 is provided on one side of the water tank 501, and a water pipe 503 is provided on the top of the water tank 501. One end of the water pipe 503 is located at the bottom center of the inner wall of the water tank 501, and a second water pump 504 is installed on the water pipe 503. One end of the second water pipe 503 is connected to the top side of the electrolytic cell 101. By providing a water cooling component 5 on one side of the electrolytic cell 101 and turning on the second water pump 504 on the water pipe 503, not only is the time spent manually adding water to the electrolytic cell 101 saved, but it also facilitates the continuous hydrogen production operation of the electrolytic component 1. This improves the hydrogen production efficiency of the hydrogen production equipment and helps to keep the electrolyzer 101 in a closed space, preventing air gases from entering the electrolyzer 101 and causing unnecessary impact on hydrogen collection. On the other hand, since a large amount of heat is generated during water electrolysis to produce hydrogen, the water cooling component 5 helps to cool the electrolyzer 101 and other equipment, removes excess heat, controls the operating temperature of the electrolyzer 101, prevents the equipment from being damaged due to overheating, and further improves the safety of the hydrogen production equipment during use.

[0028] When in use, firstly, turn on the second water pump 504 on the water cooling component 5 to add pure water for hydrogen electrolysis into the electrolysis cell 101. This not only saves the time of adding water to the electrolysis cell 101, but also helps the electrolysis component 1 to continuously produce hydrogen. It also helps to cool the electrolysis cell 101 and other equipment, remove excess heat, thereby controlling the working temperature of the electrolysis cell 101 and preventing the equipment from being damaged due to overheating, further improving the safety of the hydrogen production equipment during use.

[0029] Then, the power supply 102 on the electrolysis assembly 1 is turned on, oxygen is generated on the anode plate 104, hydrogen is generated on the cathode plate 105, the hydrogen generated on the cathode plate 105 is dried by the dryer 303 to remove the residual moisture in the hydrogen on the cathode plate 105, and the oxygen generated on the anode plate 104 is discharged through the first outlet 2.

[0030] Finally, the hydrogen gas on the cathode plate 105 moves through the permeation membrane 304 to the top of the inner side of the first gas collecting tank 301, and flows into the second gas collecting tank 401 through the second vent pipe 402 on the collecting assembly 4. The oxygen at the bottom of the first gas collecting tank 301 is discharged through the second gas outlet 305, and the first water pump 107 on the drain outlet 106 is turned on to discharge the electrolyzed water through the drain outlet 106.
