Spherical tanks for cryogenic media

Abstract

A spherical tank used for containing a low-temperature medium comprises a spherical outer tank body and a spherical inner tank body located inside the spherical outer tank body. An interlayer is formed between the outer tank body and the inner tank body. Multiple support legs are circumferentially arranged on the middle and lower portions of the inner tank body. The upper portion of each support leg is located inside the interlayer and connected with the outer wall of the inner tank body, and the lower portion of each support leg extends out of the outer tank body. The upper portion and the lower portion of the interlayer are provided with multiple temperature sensors used for monitoring the temperature of the interlayer. Multiple temperature sensors used for monitoring the temperature of the inner tank body are distributed on the wall of the inner tank body in the height direction. The portion, located inside the interlayer, of each support leg is provided with a temperature sensor used for monitoring the temperature of the interlayer portion of the support leg. According to the spherical tank used for containing the low-temperature medium, because the temperature sensors are reasonably arranged on the upper portion and the lower portion of the interlayer, the inner tank body and the interlayer portions of the support legs of the spherical tank, the temperature of the whole spherical tank can be effectively and completely observed, the problem of monitoring the temperature of the spherical tank is solved, and the safety of the spherical tank is improved.

Description

technical field [0001] The invention relates to a low-temperature medium storage tank, in particular to a spherical storage tank for loading low-temperature medium. Background technique [0002] Cryogenic medium, such as LNG and other clean energy, in recent years, with the continuous increase of national energy conservation and emission reduction, its related industries have been valued by the state and received strong support, thus developing rapidly. [0003] At present, the storage tanks for storing LNG mainly include spherical, membrane, SPB, conch and C types. Spherical storage tanks are the mainstream storage tanks for storing LNG, which usually have a double-layer outer tank structure, which includes: a spherical outer tank and a spherical inner tank inside the spherical outer tank. The inner tank is generally made of stainless steel, and the outer tank is made of carbon steel. Material, there is an interlayer between the inner tank and the outer tank, and pearlesce...

Problems solved by technology

[0005] However, at the same time, the spherical tank also has defects such as complex process structure and small interlayer space between the inner and outer tanks. As a result, it is difficult to arrange temperature monitoring points in the existing double-layer spherical tank, and it is difficult to install temperature sensors and lay cables. Unreasonable cable layout not only affects the appearance, but more seriously, it will also affect the overall safety of the spherical tank
