One end of the hydrogen purification guiding tube I 1 is provided with a prefabricated cross-shaped opening groove 7. The prefabricated cross-shaped opening groove 7 is arranged in a cross shape. A structure with an adsorption function is inserted into the inner cavity of the prefabricated cross-shaped opening groove 7. The structure with an adsorption function includes a positioning type cross-shaped insertion plate I 8 and a positioning type cross-shaped insertion plate II 9. The positioning type cross-shaped insertion plate I 8 and the positioning type cross-shaped insertion plate II 9 are combined to form a cross shape. The positioning type cross-shaped insertion plate I 8 and the positioning type cross-shaped insertion plate II 9 are inserted into the inner cavity of the prefabricated cross-shaped opening groove 7. The positioning type cross-shaped insertion plate I 8 and the positioning type cross-shaped insertion plate II 9 are arranged in a hollow shape.

[0022] Working principle: The hydrogen purification device realizes the efficient purification of hydrogen through a unique structural design and a reasonable configuration of adsorption materials. Its core working principle lies in using an underwater-connected pipeline system. Through the coordinated action of the hydrogen purification guiding tube I 1, the hydrogen purification guiding tube II 2, and the hydrogen purification guiding tube III 3, the gas entering the system is filtered and purified at multiple levels. First, the hydrogen purification guiding tube I 1 serves as the primary guiding tube. Through the insertion of the positioning type cross-shaped insertion plate I 8 and the positioning type cross-shaped insertion plate II 9, it ensures that the gas is preliminarily filtered before entering the purification device, removing large particle impurities. This process is similar to the common underwater filtration steps in a laboratory. As shown in the figure, the sealing effect of water ensures the stability and uniformity of gas flow.

[0023] After the gas passes through the first hydrogen purification guide pipe 1, it will continue to flow through the second hydrogen purification guide pipe 2 and the third hydrogen purification guide pipe 3 for further guiding and shunting. At this time, the gas will come into contact with different adsorption materials in the pre-embedded adsorption sheet 11 and the anti-detachment extension plate 12. The selection of these materials can be adjusted according to specific purification requirements. For example, activated carbon can effectively remove moisture and carbon dioxide in the gas, while molecular sieve can further purify nitrogen and oxygen impurities in hydrogen. In this process, the spherical adjustment block 1 and the spherical adjustment block 2 serve as key adjustment and fixing components to ensure sufficient contact between the adsorption material and the gas, maximizing the adsorption efficiency. This multi-level filtration and adsorption scheme can significantly improve the purity of hydrogen and is suitable for high-purity hydrogen requirements in laboratory and industrial environments;

[0024] In actual operation, the selection and configuration of the adsorption material are the key to determining the purification effect. By filling different adsorption materials in the pre-embedded adsorption sheet 11 and the anti-detachment extension plate 12, users can carry out targeted purification for different impurity components. For example, in cases where a large amount of moisture needs to be removed, activated carbon can be selected as the main adsorption material, while in cases where trace amounts of oxygen and nitrogen need to be further removed, high-efficiency molecular sieve can be selected. This flexible adsorption scheme can not only meet the hydrogen purification requirements in different scenarios but also be adjusted according to the actual situation, improving the applicability and operation flexibility of the device;

[0025] To ensure the stability and efficiency of the entire purification process, the device is also designed with an annular equidistant distribution of multiple sections of limit-type binding rubber bands 6. Through this design, the gas flow rate can be effectively controlled to ensure that the gas stays in the adsorption material for a long enough time, thereby improving the adsorption effect. In addition, through the binding effect of the anti-detachment extension plate 10 and the anti-detachment extension plate 12, the stability of the adsorption material during the purification process is guaranteed, preventing it from falling off or shifting during gas flow. This structural design not only improves the purification efficiency but also simplifies the operation of maintaining and replacing the adsorption material, reducing the maintenance cost of the device;

[0026] In summary, the hydrogen purification device achieves efficient purification of hydrogen through a clever pipeline design, reasonable configuration of various adsorption materials, and optimized configuration of adjustment components. Its structural design ensures the stability of gas flow and the efficiency of the adsorption process, achieving good purification effect and convenient maintenance. In practical applications, this device has wide applicability and is suitable for various occasions that require high-purity hydrogen, including laboratory research, industrial production, and hydrogen fuel cells. Through simple operation steps, users can easily achieve efficient purification of hydrogen, improve work efficiency, and reduce costs, with high practical value and market potential.
