Embodiment Construction

[0029] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments described here are only used for exemplification and are not used to limit the present invention.

[0030] Such as Figure 1 to Figure 4 As shown, the horizontal double-layer buried storage tank of the present invention is used to store LNG cryogenic liquid. The horizontal double-layer buried storage tank includes: outer container 1, inner container 3, submersible pump 4 and various pipelines.

[0031] The outer container 1 can be completely buried below the ground, for example, the height of the top of the outer container 1 from the ground is at least 500 mm, that is, the soil layer on the top of the outer container 1 can be at least 500 mm. The outer container 1 includes an outer cylinder, an outer left head 7 and an outer right head 10 welded to both ends of the cylinder, and an outer cylinder reinforcem...

Abstract

The invention provides a horizontal double-layer buried storage tank which comprises an outer container, an inner container, an immersed pump and a drain pipe. The outer container can completely be buried underground; the inner container is arranged inside the outer container; the immersed pump is disposed at the bottom inside the inner container; and one end of the drain pipe is connected with a liquid outlet of the immersed pump and the other end of the drain pipe extends out of the outer container. According to the invention, the outer container can completely be buried underground and the immersed pump is arranged inside the inner container. Thus, the pump and the tank are integrated as a whole and the whole body is buried underground. There is no need to specially build thermal insulation facilities such as a cryogenic pump sump and the like. Therefore, a lot of manpower, material and financial resources are saved. In addition, it is guaranteed that the immersed pump is always in a low-temperature state; heat leak of the cryogenic pump sump is minimized; overall cryogenic property of the storage tank is enhanced; and daily evaporation rate of the storage tank is reduced effectively. Accordingly, it is energy saving and environmentally friendly to use the horizontal double-layer buried storage tank.

Description

Technical field [0001] The invention relates to a low-temperature pressure vessel, in particular to a horizontal double-layer buried storage tank for storing LNG. Background technique [0002] At present, cryogenic storage tanks are mostly placed on the ground, and most of them are double-layer structures. Most of the media contained are cryogenic liquids, such as liquid oxygen, liquid nitrogen, liquid argon, liquid natural gas (LNG), liquid carbon dioxide, liquid ethylene, etc. , Storage tank related supporting pipeline requirements are relatively high, and due to factors such as fire safety considerations, the requirements for the space around the storage tank are relatively large. [0003] At the same time, in a cryogenic pressure vessel placed above the ground, when cryogenic liquid is transferred through the pump, in order to ensure that the pump is always in a low temperature state during operation, the current practice is to place the pump in an insulated cryogenic pump pool...
