Description

Technical Field

[0002] Hydrogen, as it is known, is a major industrial raw material and the most important industrial and specialty gas, with widespread applications in the petrochemical industry, electronics, metallurgy, food processing, float glass, fine organic synthesis, aerospace, and other fields. It is also an ideal secondary energy source (secondary energy refers to energy that must be produced from a primary energy source such as solar energy or coal). Under normal circumstances, hydrogen readily combines with oxygen. This property makes it a natural reducing agent, used in production to prevent oxidation. In high-temperature processes in glassmaking and in the manufacture of electronic microchips, hydrogen is added to the nitrogen shielding gas to remove residual oxygen. In the petrochemical industry, hydrogen is added to refine crude oil through desulfurization and hydrocracking. Another important use of hydrogen is the hydrogenation of fats in margarine, cooking oil, shampoo, lubricants, household cleaners, and other products. Due to its high fuel quality, the aerospace industry uses liquid hydrogen as a fuel.

[0027] See also Figure 1-4 As shown, in this embodiment, a hydrogen storage device is provided, including: a storage tank 1, a protective shell 2 is sleeved on the outer surface of the storage tank 1, a device box 3 is fixedly connected to one side of the top of the protective shell 2, and an airbag assembly 4 for increasing the buffering capacity of the storage tank 1 is sleeved inside the equipment box 3. During the transportation of the storage tank 1, the air pump 41 can be connected to an external power source to fill the interior of the inflation head 44 with gas through the U-shaped tube 42 and the connecting tube 43, and then fill the gas into the interior of the airbag ring 46, thereby causing the airbag ring 46 to expand inside the protective shell 2, thereby squeezing the storage tank 1, and providing a certain degree of flexible buffering between the storage tank 1 and the protective shell 2, thereby preventing the storage tank 1 from being damaged by impact and vibration during transportation, thereby improving the stability and protection of transportation, and a water tank 5 is fixedly connected to one side of the bottom end of the protective shell 2, and a cooling assembly 6 is provided on the surface of the water tank 5 for reducing the storage temperature of the storage tank 1.

[0028] One aspect of this embodiment is that when the ambient temperature is too high, the water pump 61 can be connected to an external power source, allowing it to extract water from the water tank 5 through the L-tube 62, then transport it to the inside of the airbag ring 46 through the first hose 63, and then enter the water tank 5 through the second hose 10, thus completing a cycle. The storage tank 1 is affected by the water temperature, thereby lowering the temperature to a certain extent. At the same time, the water temperature can be cooled by the semiconductor cooling plate 7, further lowering the temperature of the storage tank 1, preventing the storage tank 1 from being affected by high temperature, and thus improving the stability of hydrogen storage. It should be noted that all electrical equipment involved in this application can be powered by batteries or external power supplies.
