Problems solved by technology

Due to the limitation of the double-layer tank structure of the low-temperature storage tank itself, if multiple storage tanks are installed side by side, the interlayer part of each storage tank will waste the installation space. At the same time, the outer tank itself uses more materials, and each storage tank It must have a complete set of valve groups, which further increases the user's use cost

Embodiment 1

[0015] Example 1: Cryogenic storage tanks are used to store cryogenic liquids, such as liquid nitrogen, liquid oxygen, and liquid ammonia. This liquid has a wide range of applications in industry, so it is often necessary to transport it over long distances and install cryogenic storage tanks in the factory. The existing low-temperature storage tank adopts a double-layer structure of an outer shell and an inner tank, and an interlayer for heat insulation is also arranged between the two. The present invention improves the low-temperature storage tank by placing an inner tank group composed of six inner tanks 2 inside one shell 1 at the same time. Six liners are neatly arranged in a row, and each liner 2 is fixed on the inner surface of the shell 1 through a fiberglass support (not shown in the figure). The outer surface of the liner 2 is wound with multiple layers of glass fiber paper 6 as an insulating layer. The distance between two adjacent inner tanks 2 is the same as th...

Embodiment 2

[0017] Embodiment 2: In this embodiment, multiple layers of glass fiber paper 6 are wrapped around the outer surface of the inner tank group as a thermal insulation layer, and there is no glass fiber paper 6 in the gap between two adjacent inner tanks 2 . Other parts are identical with embodiment 1.

Abstract

The invention discloses a low temperature storage tank. The low temperature storage tank comprises a shell, wherein an inner container group is arranged inside the shell, and the inner container group is composed of multiple inner containers. All the inner containers of the inner container group are communicated with each other by virtue of pipelines and are communicated with outside by virtue of a single valve group. The low temperature storage tank has the advantages that multiple inner containers are compactly fixed in one shell, volume of a low temperature storage tank with the same capacity is reduced, and the low temperature storage tank is convenient to mount and transport; and multiple inner containers are uniformly connected with one valve group, quantity of the valve group is also reduced, and cost is reduced.

Description

technical field [0001] The invention relates to a low-temperature storage tank, which belongs to the sealing field. Background technique [0002] Vacuum insulated cryogenic pressure vessels (cryogenic storage tanks) are mainly used to store and transport cryogenic liquefied gases such as liquid oxygen, liquid nitrogen, liquefied natural gas and other cryogenic media. The current cryogenic storage tanks are composed of a double-layer structure of an inner tank and an outer shell. The inner tank stores low-temperature liquefied gas, and the interlayer between the inner tank and the outer shell is insulated by high-vacuum multi-layer winding or vacuum-filled pearlescent sand. [0003] Because the storage of cryogenic medium requires very high heat insulation, the use of double-layer structure high-vacuum interlayer is an ideal heat insulation method, but in some special occasions, such as the user needs to use multiple cryogenic storage tanks at the same time due to the small i...
