Abstract

The invention discloses a combined polytetrafluoroethylene liquid state hydrogen storage tank and relates to the technical field of gas storage tanks. The combined polytetrafluoroethylene liquid statehydrogen storage tank comprises a tank body which is made from a polymer material similar to polytetrafluoroethylene. The tank body comprises a storage tank liner, a plurality of layers of intermediate housings, a storage tank outer wall and a tank sealing flange, wherein the intermediate housings are assembled on the outer side of the storage tank liner; the storage tank outer wall is assembledon the intermediate housings on the outer side; and the tank sealing flange is assembled at the upper end of the storage tank liner; a heat insulation layer and a vacuum layer are successively arranged on the side, facing the storage tank liner, of each intermediate housing; and a hollow layer is arranged on the side, facing the intermediate housings, of the storage tank outer wall. By adopting the technical scheme, the combined polytetrafluoroethylene liquid state hydrogen storage tank has the advantages of reducing the rate of gasification of the liquid state hydrogen storage tank, further prolonging the storage time of liquified hydrogen, alleviating the weight of the storage tank, simplifying the production process of the storage tank, transporting liquid state hydrogen conveniently and enhancing the safety of the storage tank.

Description

technical field [0001] The invention relates to the technical field of gas storage tanks, in particular to a combined polytetrafluoroethylene liquid hydrogen storage tank. Background technique [0002] Today, with increasing emphasis on environmental sanitation, controlling the discharge of pollutants is the consensus of all mankind. Therefore, the application of green energy is put on the agenda. Hydrogen energy is considered a real green energy because it is discharged into water. The storage and transportation of liquid hydrogen is an important link to ensure the utilization of hydrogen energy. [0003] Hydrogen is the lightest known atom, and its density is extremely low at room temperature and normal atmospheric pressure, so it needs to be stored at a higher density before it can be used in vehicles. There are two ways to increase the density: 1. Compression: The current common practice is to compress hydrogen to 35 MPa or 70 MPa. This requires a high-strength storage...
