Problems solved by technology
Gasification of liquid hydrogen is prone to temperature stratification, which increases evaporation loss, affects the output quality of liquid hydrogen, and even causes liquid hydrogen to evaporate suddenly under the Managoni effect, which deteriorates the performance of the storage tank and forms a sharp air pillow. Pressure rises, creating a safety hazard

The invention provides a low-temperature liquid storage and transportation container to solve the problems that when low-temperature liquid is stored and transported by an existing storage and transportation container, the temperature stratification phenomenon is prone to occurring, and the gasification loss is large. The container comprises a tank body, wherein the tank body comprises an inner shell and an outer shell; a plurality of heat conduction pieces which are arranged in the inner shell at intervals, wherein each heat conduction piece is made of a metal heat conduction material and is connected with the inner wall of the inner shell. The low-temperature liquid stored and transported in the container is uniform in temperature distribution and small in evaporation loss, and the container is good in use performance and high in safety.
Description
technical field [0001] The invention belongs to the technical field of cryogenic liquid storage and transportation equipment, and in particular relates to a cryogenic liquid storage and transportation container. Background technique [0002] Cryogenic liquids such as liquid hydrogen, liquid helium, liquid nitrogen, liquid oxygen, etc. consume a lot of energy during the liquefaction process, so reducing their gasification loss during storage and transportation has an important role and significance. Taking liquid hydrogen as an example, hydrogen energy is an important carrier for building a multi-energy supply system based on clean energy. With the rapid development of hydrogen energy application in my country, hydrogen production, hydrogen liquefaction, hydrogen storage, hydrogen transportation and hydrogen consumption The field will be developed rapidly and deeply. The liquefaction of hydrogen consumes a lot of energy, and reducing the gasification loss of liquid hydrogen i...
