Description

Technical Field

[0001] The utility model relates to the technical field of filter tanks, in particular to a hydrogen gas storage buffer filter tank. Background Technique

[0002] The hydrogen gas storage buffer filter tank is a key device used in a hydrogen gas treatment system, aiming to filter, store, and buffer hydrogen gas. Its main functions include removing impurities and particles in the hydrogen gas, protecting system components from contamination and damage, and balancing the hydrogen gas pressure to ensure the stable operation of the system.

[0003] The patent with the patent announcement number CN212080856U discloses a hydrogen gas storage buffer filter tank, including a buffer tank. The buffer tank is in a circular tube shape, and an air inlet and an air outlet are respectively arranged at both ends of the buffer tank. It also includes a heat exchange shell and a filter cylinder. The heat exchange shell is sealingly sleeved outside the buffer tank, and a heat exchange interlayer is formed between the inner circumferential wall of the heat exchange shell and the outer circumferential wall of the buffer tank. A guide spring is arranged in the heat exchange interlayer. The guide spring is sleeved outside the buffer tank, and both ends of the guide spring are correspondingly arranged with the inlets and outlets at both ends of the heat exchange shell. The filter cylinder is located inside the buffer tank. One end of the filter cylinder is closed, and the other end is communicated with the air inlet of the buffer tank. The filter cylinder includes an inner filter cylinder and an outer filter cylinder, and a filter element layer is arranged between the inner filter cylinder and the outer filter cylinder. The purpose of this utility model is to solve or at least alleviate the problems of heat generation during the use of the current hydrogen buffer tank and the inability to block solid particles from entering the equipment in use, and to provide a hydrogen gas storage buffer filter tank.

[0004] However, the current filter tank has the following problems: Some solid particles will be generated during the production and compression of hydrogen gas in the filter tank. Particles with adhesiveness or adsorptivity will adhere to the surface of the filter screen in the filter tank, making it difficult for the filter screen in the filter tank to normally filter hydrogen gas. Therefore, we propose a large-capacity aluminum alloy inner-liner hydrogen fuel bottle. Content of the Utility Model
