Abstract

The invention discloses a hydrogen storage tank with an external heat exchanging structure, and belongs to the hydrogen storage technical field of the hydrogen energy field. The hydrogen storage tank comprises the following structure: a skirt support is disposed at the bottom of a tank body; a hydrogen storage material bed is disposed in the tank body; a gas guide tube is disposed at the center position in the tank body and pass straight through the tank mouth from the tank bottom; a filter is installed in the tank mouth, and a hydrogen cylinder valve is installed at the external of the tank mouth; a housing is disposed at the external of the tank body, two ends of the housing are respectively provided with a heat conduction liquid inlet and a heat conduction liquid outlet; and a heat exchanging structure is arranged in an annular chamber between the housing and the tank body. The heat exchanging structure is in the shape of a straight flow, a winding flow, a single spiral or multiple spirals, and the hydrogen storage material bed is a uniform mixed body of a hydrogen storage material and heat conduction fiber. The provided hydrogen storage tank is simple in structure, easy for preparation and processing, and low in cost. Compared with conventional hydrogen storage tanks, the hydrogen storage tank provided by the invention has relatively excellent heat exchanging effect and relatively excellent hydrogen desorption performance.

Description

technical field

[0001] The invention belongs to the technical field of hydrogen storage in the field of hydrogen energy, and in particular relates to a hydrogen storage tank with an external heat exchange structure. Background technique

[0002] With the development of society, fossil fuels such as coal, oil, and natural gas can no longer meet the growing needs of human beings. At the same time, the use of fossil fuels has caused the deterioration of the ecological environment, such as the greenhouse effect. In addition, coal, oil, natural gas, etc. are non-renewable resources with limited reserves on the earth, and it is impossible for human beings to depend on them all the time. Therefore, many countries are researching and developing new alternative energy sources, such as hydrogen energy, wind energy, solar energy, nuclear energy, biomass energy, water energy, ocean energy, etc. The combustion calorific value of hydrogen is high, and the energy after burning per kilogra...
