Cryogenic medium storage and transportation container

Abstract

A cryogenic medium storage and transportation container comprises a shell, a medium container, a refrigerant container, a cold shield and a cooling pipeline. The medium container is arranged in the shell and is used for storing the cryogenic media, the refrigerant container is arranged in the shell, is located at one end of the medium container and is used for storing a refrigerant medium, and theboiling point of the refrigerant medium is higher than that of the cryogenic medium. The cold shield is arranged in the shell and covers the periphery of the medium container, and the shape of the cold shield is matched with that of the medium container. The cooling pipeline is led out from the lower portion of the refrigerant container, sequentially extends from the bottom of the cold screen tothe end, away from the refrigerant container, of the cold screen, from the bottom of the end of the cold screen to the top and from the top of the cold screen to the end, corresponding to the refrigerant container, of the cold screen, and is led to the upper portion of the refrigerant container or led out of the shell.

Description

technical field [0001] The invention relates to a cryogenic medium storage and transport container. Background technique [0002] With the development of the economy and the popularization of low-temperature technology, such as the application of refrigerated liquefied gases, the demand for cryogenic containers for storage and transportation of refrigerated liquefied gases is also increasing, especially for liquid hydrogen and liquid helium. It is very difficult to store the medium with extremely low latent heat of vaporization for a long time. Relevant data calculations show that if a 50L multi-layer adiabatic cold medium container with a daily evaporation rate of 1% is used to store liquid helium, the daily evaporation rate is expected to reach about 50%, which obviously cannot meet the storage requirements. Therefore, how to effectively store and transport for a long time has become the key to solving this problem. [0003] Existing storage and transportation containers...

AI Technical Summary

Problems solved by technology

[0003] Existing storage and transportation containers usually use Dewar containers or small containers (25-100L), which adopt multi-screen or multi-layer insulation methods, and single or multiple vapor cooling screens are welded on the exhaust neck of the container to keep the container Surrounded, but more difficult to manufacture, larger in mass, and only suitable for short-term storage and short-distance transportation
