Abstract

The invention discloses a vertical container used for storing low-temperature liquid. The vertical container comprises a shell provided with a seal cavity, an inner container mounted in the cavity and used for storing the low-temperature liquid and a cold source container used for storing liquid nitrogen; the outer side of the inner container is coated with a liquid nitrogen cold shield, a liquid nitrogen cooling pipe is arranged on the liquid nitrogen cold shield, and the liquid nitrogen cooling pipe and the cold source container are communicated to form a liquid nitrogen circulation loop; and the vertical container mainly adopts a heat insulation manner combining vacuum multi-layer heat insulation with the liquid nitrogen cold shield to reflect the excellent heat insulation performance. An inner container used for storing liquid nitrogen media is arranged in the vertical container, the independent liquid nitrogen cold source container and the independent liquid nitrogen cold shield are arranged, through dissipation of liquid nitrogen in the cold source container, the heat wall temperature of the liquid nitrogen container is reduced to 77 K from 300 K, the radiant heat flux is reduced to 1/150 to 1/200 of the original flux, and therefore the aim of greatly reducing the daily evaporation rate loss of the container is achieved.

Description

technical field [0001] The invention relates to storage and transportation equipment for cryogenic liquids, in particular to a vertical container for storing cryogenic liquids such as liquid hydrogen. It belongs to the field of cryogenic technology. Background technique [0002] In the field of cryogenic technology, cryogenic liquids refer to gases that exist in liquid form below -160°C, such as liquid oxygen, liquid nitrogen, liquid argon, liquid hydrogen, liquid helium, liquid methane and LNG, etc., which are widely used in industrial production, hospitals and in daily life. A cryogenic liquid storage container is usually a double-layer structure consisting of an inner tank and an outer shell. There is a vacuum layer between the inner tank and the outer shell, and a heat insulating material is filled between the vacuum layers to ensure the heat insulation effect. [0003] At present, most of the existing cryogenic liquid storage containers adopt the type of high-vacuum m...
