Background
The fixed vacuum heat-insulating deep-cold pressure container is usually in two heat-insulating forms, one is high-vacuum multilayer heat insulation, the other is vacuum powder heat insulation, and the heat-insulating effect of the high-vacuum multilayer heat insulation is slightly better than that of the vacuum powder heat insulation. The temperature of the liquid hydrogen is very low, the boiling point is 20.35K, the temperature difference between the liquid hydrogen and the environment is very large, and in order to ensure the vacuum heat insulation performance of the whole storage tank, the heat insulation adopts a high vacuum multilayer heat insulation mode.
Disclosure of Invention
The design purpose is as follows: the design of the fixed high-vacuum heat-insulation vertical liquid hydrogen storage tank not only can meet the low-temperature performance requirements (including vacuum performance and vacuum heat-insulation performance) of the liquid hydrogen medium, but also has the advantages of economical and practical structure and simple manufacture.
The design scheme is as follows: in order to achieve the above design objective. The utility model is structurally designed: the fixed vacuum heat-insulating deep-cold pressure container is usually in two heat-insulating forms, one is high-vacuum multilayer heat insulation, the other is vacuum powder heat insulation, and the heat-insulating effect of the high-vacuum multilayer heat insulation is slightly better than that of the vacuum powder heat insulation. The temperature of the liquid hydrogen is very low, the boiling point is 20.35K, the temperature difference between the liquid hydrogen and the environment is very large, and in order to ensure the vacuum heat insulation performance of the whole storage tank, the heat insulation adopts a high vacuum multilayer heat insulation mode. The main body structure of the fixed high vacuum heat insulation vertical liquid hydrogen storage tank is an innermost inner container, the middle is heat insulation material, a pipeline system and a supporting accessory, and the outermost layer is an outer container.
The inner container is formed by welding a cylindrical barrel and upper and lower elliptical sealing heads, and the material is S31608-LH stainless steel. The inner container is used for storing low-temperature liquid hydrogen. The outer container is made of Q345R steel plate, and has a structure similar to that of the inner container.
The multi-layer heat insulation material formed by winding aluminum foil and glass fiber on the outer surface of the inner container reduces the radiation heat transfer of the inner container and the outer container through aluminum foil reflection, and increases the heat resistance of the heat conduction of residual gas through glass fiber paper, so that the heat transfer of the residual gas between the inner container and the outer container is reduced, the cold loss of the inner container is finally reduced, and the vacuum heat insulation performance is ensured.
The inner container and the outer container are connected through three stainless steel lower suspenders, and have enough length to reduce heat transfer of the lower suspenders.
The inner container is supported and horizontally laid on the inner wall of the outer container through eight radial support columns, and an axial support is arranged at the top of the inner container. The radial support is used for bearing the weight of the inner container and the force generated by the transportation acceleration in the manufacturing and transportation processes, and simultaneously is used for ensuring the coaxiality of the inner container and the outer container. The axial support is adapted to withstand the axial forces generated by the inner container during transport. In order to reduce heat conduction, the radial and axial support materials adopt epoxy glass fiber reinforced plastic structures.
The pipeline system comprises an overpressure relief pipe, a hydrogen exhaust system, a top spraying liquid filling pipeline, a bottom liquid filling pipeline, a liquid outlet pipeline, a pressurizing pipeline, an overflow pipeline, a liquid level and pressure measuring pipeline and accessories.
The technical scheme is as follows: the utility model provides a fixed high vacuum thermal insulation vertical liquid hydrogen storage tank, the inner container is formed by cylindrical barrel and upper and lower oval head welding and the multilayer insulating material that the inner container surface winding in proper order comprises aluminium foil and glass fiber, and outer container structure is similar with the inner container, links to each other through three stainless steel suspender down between inner container and the outer container, and pipe system is located liquid hydrogen storage tank bottom and communicates with liquid hydrogen storage tank.
Compared with the background technology, the utility model not only can meet the low-temperature performance requirement of the liquid hydrogen medium, but also has the advantages of economical and practical structure and simple manufacture.
