Embodiment Construction

[0018] The following is a detailed elaboration and description of the inner tank suspension type cryogenic liquid storage and transportation container of the present invention in conjunction with the accompanying drawings and embodiments.

[0019] like figure 1 As shown, the container body of the inner tank suspension type cryogenic liquid storage and transportation container of the present invention is composed of an outer tank 1 and an inner tank 2 . A vacuum cavity is formed between the outer bladder 1 and the inner bladder 2 . The liner 2 is a non-magnetic material. On its outer wall, in addition to arranging traditional heat insulating materials, there are also a number of discrete superconductors 3 fixed on its lower and upper individual positions through structures with high thermal conductivity. The superconductors 3 and Liner 2 has good thermal contact. On the inner wall of the outer bladder 1 , a permanent magnet 4 is arranged at a position corresponding to the sup...

Abstract

The invention relates to a thermal insulating vessel, in particular to a low temperature liquid storage and transportation vessel. An inner lining suspension type low temperature liquid storage and transportation vessel comprises an outer lining and an inner lining, wherein a vacuum cavity is formed between the outer lining and the inner lining; a plurality of superconduction magnetic suspension units and a movable rigid support device are arranged in the vacuum cavity; and the arrangement position of the movable rigid support device is higher than that of the superconduction magnetic suspension units at the lower part to realize conversion of rigid contact and magnetic suspension between the outer lining and the inner lining. Compared with the prior art, the suspended inner lining can effectively reduce a heat bridge and reduces heat conduction heat leakage of the storage tank to prolong the storage time of low temperature liquid and reduce the potential safety hazard caused by leakage.

Description

technical field [0001] The invention relates to a thermal insulation container, in particular to a low temperature liquid storage and transportation container. Background technique [0002] The production, storage, and transportation of cryogenic liquids such as liquid hydrogen, liquid nitrogen, and LNG are inseparable from cryogenic storage tanks with excellent cold and heat insulation properties. As a cryogenic liquid storage device, the cryogenic liquid storage tank can operate safely and reliably not only with the strength of the storage tank itself, but also with the leakage heat of the tank body. Leakage of heat will lead to short storage time of cryogenic liquids and increase the safety hazards caused by leakage. Therefore, the size of the leakage heat is an important index to measure the cryogenic liquid storage tank. At present, the storage and transportation tanks of low-temperature liquefied gas generally use a double-layer structure. The inner and outer tanks a...
