Problems solved by technology

This structure is an upgraded structure of the metal tree root tie connection described in its patent. Affected by the size of the lower support structure, it has certain requirements for the width of the vacuum interlayer between the inner and outer cylinders, and has requirements for the overall process and manufacturing of the equipment. It is relatively high, and its upper support has no FRP positioning and fastening device. Due to the influence of the slope of the cylinder, in actual use, there may be permanent contact between the upper support FRP and the outer wall of the inner cylinder.

Abstract

The invention relates to a vertical low-temperature container. The technical problem that in the prior art, when a vertical low-temperature container stores a medium with the temperature reaching -196 DEG C or lower, the heat insulating property of a supporting structure of the vertical low-temperature container is severely decreased is mainly solved. The vertical low-temperature container comprises a liner and a shell. An end socket axial support is arranged between the outer side of the top of the liner and the inner side of the top of the shell. A steel pipe glass steel support is arranged between the outer side of the bottom of the liner and the outer side of the bottom of the shell. According to the technical scheme, the problem is well solved, and the vertical low-temperature container can be used for storing the low-temperature medium with the temperature being -196 DEG C or lower.

Description

technical field [0001] The invention specifically relates to a vertical cryogenic container. 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 composed of an inner tank 10 and an outer shell 1. There is a vacuum interlayer between the inner tank 10 and the outer shell 1. The stability of the inner container and the outer shell 1 is ensured by a suitable support structure, and the The heat conduction between the inner container and the external environment ensures the overall heat insulation effect of the cryogenic container; the vacuum service life of the cryogenic container is ensured by placing an adsorbent at a suitable ...
