[0020] Please see Figure 1 , Figure 2 and Figure 3As shown, a vertical teaching aid for hydrogen production via water electrolysis includes a mounting support plate 1, a water tank 2, a water purification module 3, an electrolyzer 4, a hydrogen output module 5, a power supply module 6, a display screen 7, and an electrical control box 8. The water tank 2, water purification module 3, electrolyzer 4, hydrogen output module 5, power supply module 6, and display screen 7 are mounted on the front of the mounting support plate 1, while the electrical control box 8 is mounted on the back of the mounting support plate 1. Meanwhile, the water purification module 3 and the electrolyzer 4 are positioned below the water tank 2, with the water purification module 3 connected to both the water tank 2 and the electrolyzer 4. The power supply module 6 is located on one side of the water tank 2 and above the electrolyzer 4. The hydrogen output module 5 and the display screen 7 are located on the side of the power supply module 6 furthest from the water tank 2, and the hydrogen output module 5 is connected to the hydrogen output port of the electrolyzer 4 via a pipeline. The power supply module 6, water purification module 3, electrolyzer 4, hydrogen output module 5, display screen 7, and electrical control box 8 are electrically connected.

[0021] The water purification module 3 includes a water pump 31, a resin filter 32, a conductivity sensor 33, a flow meter 34, and a water supply pipeline 35. One end of the water supply pipeline 35 is connected to the water tank 2, and the other end is connected to the electrolysis cell 4. The water pump 31, resin filter 32, conductivity sensor 33, and flow meter 34 are sequentially arranged on the water supply pipeline 35. The water pump 31 is used to transport water from the water tank 2 to the electrolysis cell 4. The resin filter 32 can purify the water, remove impurities and ions, and improve water quality to ensure the smooth progress of the electrolysis reaction. The conductivity sensor 33 can monitor the conductivity of the water in real time, and the flow meter 34 can monitor the water flow rate and transmit the relevant data to the electrical control box 8, which is then displayed on the display screen 7, making it easy for students to understand the impact of water quality and water flow on the electrolysis reaction.

[0022] The oxygen outlet port of electrolytic cell 4 is connected to water tank 2 via oxygen outlet pipeline 41. This arrangement allows the oxygen generated by electrolytic cell 4 and the steam mixed with oxygen to be transported to water tank 2, where the steam liquefies and remains in the water tank.

[0023] The hydrogen output module 5 includes a hydrogen delivery pipeline 51, a gas-liquid separator 52, a first purification column 53, a second purification column 54, a dust filter 55, a gas flow meter 56, a one-way valve 57, and a hydrogen storage tank 58. One end of the hydrogen delivery pipeline 51 is connected to the hydrogen outlet port of the electrolyzer 4, and the other end of the hydrogen delivery pipeline 51 is connected to the hydrogen storage tank 58. The gas-liquid separator 52, the first purification column 53, the second purification column 54, the dust filter 55, the gas flow meter 56, and the one-way valve 57 are sequentially arranged on the hydrogen delivery pipeline 51. The hydrogen produced by electrolyzer 4 first enters the gas-liquid separator 52 through the bottom inlet. The gas-liquid separator 52 can separate the water entrained in the hydrogen, improving the dryness of the hydrogen. Then, the hydrogen flows out from its top outlet and enters the first purification column 53 and the second purification column 54 in sequence to further remove impurities from the hydrogen and improve the purity of the hydrogen. The dust filter 55 can filter out dust particles in the hydrogen to ensure the cleanliness of the hydrogen. The gas flow meter 56 is used to monitor the flow rate of the hydrogen, and the one-way valve 57 can prevent the backflow of hydrogen in the hydrogen storage bottle 58 to ensure the safety and stability of the hydrogen collection process. The hydrogen storage bottle 58 is used to store the prepared hydrogen for subsequent teaching demonstrations and use.

[0024] A pressure relief valve 59 is also installed on the hydrogen delivery pipeline 51 between the second purification column 54 and the dust filter 55. When the pressure in the hydrogen delivery pipeline 51 exceeds the set value, the pressure relief valve 59 will automatically open to release the excess pressure, prevent the pipeline from being damaged due to excessive pressure, and ensure the safe operation of the entire device.

[0025] A pressure sensor 510 is also installed on the hydrogen delivery pipeline 51 between the dust filter 55 and the gas flow meter 56. The pressure sensor 510 can monitor the pressure in the hydrogen delivery pipeline 51 in real time and transmit the pressure data to the electrical control box 8, which is then displayed on the screen 7, allowing students to understand the pressure changes during the hydrogen delivery process.

[0026] The gas-liquid separator 52 is located on the side of the power module 6 away from the water tank 2 and on the upper right of the electrolyzer 4. This layout makes the distance between the gas-liquid separator 52 and the electrolyzer 4 moderate, which facilitates the transportation of hydrogen, and also makes the entire device more compact and the layout more reasonable.

[0027] The first purification column 53, the second purification column 54, the dust filter 55, the gas flow meter 56, the one-way valve 57, and the hydrogen storage tank 58 are arranged sequentially at the lower right of the gas-liquid separator 52. This arrangement allows for smoother connections between the components, enabling hydrogen to pass smoothly through each component for processing and collection. It also facilitates the demonstration and explanation of each component during teaching.

[0028] The bottom of the gas-liquid separator 52 is also connected to the water tank 2 via a water outlet pipe 521. The water separated by the gas-liquid separator 52 can flow back to the water tank 2 through the water outlet pipe 521, realizing the recycling of water resources, reducing water waste, and also allowing students to understand the concept of resource recycling.

[0029] The electrical control box 8 is electrically connected to the conductivity sensor 33, water flow meter 34, pressure sensor 510, gas flow meter 56, display screen 7, water pump 31, electrolytic cell 4, power module 6, etc., and is used to receive data from each monitoring component, control the operation of each execution component, and transmit the data to the display screen 7 for display.

[0030] The power module 6 is fixedly installed on the right side of the water tank 2 and above the electrolyzer 4 by a bracket. Its output end is electrically connected to the electrolyzer 4, the water purification module 3, the hydrogen output module 5, the display screen 7, the electrical control box 8 and other electrical components to supply power to the entire device.

[0031] Display screen 7 is installed on the side of the gas-liquid separator 52 away from the power module 6 and located on the upper right side of the electrolyzer 4. It is electrically connected to the control box 8 and can display data collected in real time from monitoring components such as conductivity sensor 33, water flow meter 34, pressure sensor 510, and gas flow meter 56. It can also display the device's operating status (e.g., running, paused). Display screen 7 is equipped with a power switch, start button, pause button, and emergency stop button for convenient operation by teachers. The placement of display screen 7 is reasonable, facilitating observation by teachers and students. It clearly displays various parameters in the water electrolysis hydrogen production process, such as water conductivity, water flow rate, hydrogen flow rate, and hydrogen pressure, helping students better understand the entire water electrolysis hydrogen production process.

[0032] When this novel vertical teaching aid for hydrogen production via water electrolysis is in operation: First, the electrical control box 8 is turned on by operating the display screen 7, and the power module 6 supplies power to the entire device.

[0033] Water in tank 2 is pumped by pump 31 and flows through water pipeline 35, passing through resin filter 32, conductivity sensor 33 and water flow meter 34 before entering electrolytic cell 4.

[0034] The resin filter 32 purifies the water, while the conductivity sensor 33 and the water flow meter 34 monitor the conductivity and flow rate of the water, respectively, and transmit the data to the electrical control box 8 for display on the screen 7.

[0035] Electrolyzer 4 undergoes water electrolysis under the power supply of power module 6, producing hydrogen and oxygen.

[0036] The generated oxygen flows back to the water tank 2 through the oxygen outlet pipeline 41, while the generated hydrogen enters the gas-liquid separator 52 through the hydrogen delivery pipeline 51. The gas-liquid separator 52 separates the moisture from the hydrogen, and the separated moisture flows back to the water tank 2 through the water outlet pipeline 521. The dried hydrogen then passes through the first purification column 53, the second purification column 54, and the dust filter 55 for purification and filtration to remove impurities and dust particles. During the hydrogen delivery process, the pressure relief valve 59, the pressure sensor 510, and the gas flow meter 56 serve the functions of pressure relief protection, pressure monitoring, and flow monitoring, respectively, and transmit the relevant data to the electrical control box 8 for display on the screen 7.

[0037] The purified hydrogen gas, after processing, enters the hydrogen storage bottle 58 through the one-way valve 57 for storage, so that it can be used for subsequent teaching.

[0038] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
