Example Embodiment

[0025] Example 1

[0026] See figure 1 , This embodiment provides a cryogenic container 1, including an outer shell 11 and an inner tank 12 arranged inside the outer shell 11. The inner tank 12 is used to contain cryogenic medium, and an interlayer is also provided between the outer shell 11 and the inner tank 12 13. Further, the cryogenic container 1 of this embodiment further includes a pressurizing passage 14 which includes a hollow medium channel 141 for medium to circulate.

[0027] Specifically, the pressurizing passage 14 of this embodiment is connected to the outer casing 11, and the pressurizing passage 14 surrounds the outer casing 11 in the circumferential direction and is distributed along the axial direction of the outer casing 11. In this embodiment, the inlet of the medium channel 141 communicates with the liquid phase space 121 of the inner tank 12, and the outlet of the media channel 141 communicates with the gas phase space 122 of the inner tank 12.

Example Embodiment

[0043] Example 2

[0044] See image 3 The structure of the low-temperature container 1 in this embodiment is roughly the same as that of the first embodiment. The main difference is that: the pressurizing passage 14 in this embodiment includes a plurality of circumferential passages 142 surrounding the outer shell 11, and a plurality of The annular passages 142 are arranged at intervals along the axial direction of the outer shell 11, and a connecting passage 143 is provided between two adjacent annular passages 142, so that a plurality of annular passages 142 communicate with each other.

[0045] Further, in this embodiment, the outer liquid pipe 152 communicates with the annular passage 142 close to the liquid space 121 of the inner tank 12, and the outer gas pipe 162 communicates with the annular passage 142 close to the gas phase space 122 of the inner tube, thereby reducing pipelines. The length of the layout reduces production costs.

[0046] In summary, the cryogenic contain...

Abstract

The invention provides a low temperature vessel. The low temperature vessel comprises a shell body and an inner tank arranged inside the shell body, an interlayer is arranged between the shell body and the inner tank, the low temperature vessel further comprises a pressurizing passage, the pressurizing passage is connected to the shell body, the pressurizing passage surrounds the shell body in thecircumferential direction of the shell body and is distributed in the axial direction of the shell body, and a hollow medium channel is formed; and an inlet of the medium channel communicates with aliquid-phase space of the inner tank, and an outlet of the medium channel communicates with a gas-phase space of the inner tank. The low temperature vessel has low self-boosting cost and does not needadditional energy consumption, the leakage of the internal medium can be further avoided, and the overall safety of the equipment is ensured; meanwhile, the low temperature vessel eliminates an external booster, and the pipe distributing space of the vessel is not only increased, but also the self weight of the equipment is reduced; and in addition, the pressurizing passage surrounding the shellbody in the circumferential direction of the shell body and extending in the axial direction of the shell body can further play a role of an enhancing ring, and the overall structural strength of thewhole cryogenic low temperature vessel is improved accordingly.

Description

technical field [0001] The invention relates to the field of cryogenic equipment, in particular to a cryogenic container. Background technique [0002] The cryogenic containers are all insulated with high vacuum heat insulation, thereby reducing the heat leakage of the container and the vaporization and evaporation of the internal storage medium. However, when using the internal low-temperature medium, there should be a certain pressure inside the container. Therefore, in actual operation, it is necessary to adopt pressurization measures for cryogenic containers. [0003] At present, in the field of low-temperature equipment, especially in the low-temperature tank container industry, heat exchange gasification and electric heating are mainly used for pressurization. Among them, heat exchange gasification mainly uses external coils and spiral finned tubes. The main defect of this solution is that once the external pipeline is damaged or other accidents, a large amount of lo...
