The horizontal container for storing the low-temperature liquid comprises a shell and an inner container, a cold screen is arranged between the inner container and the shell, and the cold screen comprises a metal screen and a barrel-shaped structure with an opening in one end and is arranged outside the inner container in a sleeving mode; the cold source container is used for storing a cooling medium and is provided with a disc-shaped structure for sealing a containing cavity, and the outer edge of the cold source container is connected with the open end of the metal screen; the liquid cooling pipe is provided with a cooling medium inlet and a cooling medium outlet, the cooling medium inlet is communicated with the lower portion of the cold source container, the cooling medium outlet is communicated with the upper portion of the cold source container, and the liquid cooling pipe is of a U-shaped structure from the cooling medium inlet to the cooling medium outlet, extends along the surface of the metal screen and is connected with the surface of the metal screen. The cold source container is connected with the opening end of the metal screen, the inner container is wrapped between the metal screen and the cold source container, the cold source container is used for maintaining the low temperature of the near end of the metal screen, the liquid cooling pipe is used for maintaining the low temperature of the far end of the metal screen, and therefore heat is prevented from invading the inner container.
Description
technical field [0001] The invention belongs to the technical field of storage and transportation equipment for cryogenic liquids, and in particular relates to a horizontal container for storing cryogenic liquids. 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. They are widely used in industrial production, hospitals and in daily life. The cryogenic liquid storage container is usually a double-layer structure composed of an inner liner and an outer shell. There is a vacuum layer between the inner liner and the outer shell, and a thermal insulation material is filled between the vacuum layers to ensure the thermal insulation effect. [0003] At present, most of the existing cryogenic liquid storage containers adopt high-vacuum multilayer insulation or vacuum powder insu...
