Abstract

The invention relates to a vertical storage tank, which comprises an inner liner, an outer liner and legs protruded on the surface of the outer liner, wherein the bottom of the inner liner is provided with an inner gland; the bottom of the outer liner is provided with an outer gland; a support device which is in the same line with the legs is supported between the inner gland and the outer gland; and the support device comprises a first support piece which supports the inner gland, a second support piece which supports the outer gland and a heat insulating piece which is arranged between the two support pieces. The support device of the vertical storage tank has reasonable and effective supporting function, thereby increasing the volume of the vertical storage tank, and making the volume of vertical vacuum oxygen, nitrogen, argon storage tanks increase to more than 200 cubic meters.

Description

Technical field

[0001] The invention relates to a vertical storage tank, in particular to the supporting structure of a vertical vacuum fixed storage tank. Background technique

[0002] The storage tank is a cryogenic container used to store and transport liquefied natural gas, liquid oxygen, liquid nitrogen, liquid hydrogen and liquid helium. The fixed vertical storage tank is for long-term storage of liquefied gas, and effective thermal insulation measures must be adopted. The storage tank is usually a double-layer structure. The inner cylinder (also known as the inner tank) stores liquefied gas, and an insulating interlayer is formed between the inner cylinder and the outer cylinder (outer bladder) to reduce the introduction of conduction, convection, and radiation into the inner cylinder. Heat. The main performance index of the storage tank is the evaporation rate. The thermal insulation form of the storage tank includes ordinary thermal insulation, high vacuum thermal insula...
