DOUBLE SHELL CYLINDRICAL LIQUID HYDROGEN TANK
To provide a large-scale double shell cylindrical liquid hydrogen tank in which a thermal insulation performance of an inner tank bottom support structure is greatly improved.SOLUTION: A double shell cylindrical liquid hydrogen tank includes an inner tank, an outer tank, and an inner tank bottom support structure 30 to be provided between a bottom plate of the outer tank and the bottom plate of the inner tank. A space between the inner tank and the outer tank is kept in a vacuum. The inner tank bottom support structure includes: a lower cylindrical body arrangement 33 where a plurality of cylindrical bodies 33a of a same height is arranged and placed in a line direction and a row direction on the bottom plate of the outer tank; a lower floor plate 34 placed on the lower cylindrical body arrangement; an upper cylindrical body arrangement 35 where a plurality of cylindrical bodies 35a of the same height is arranged and placed in the line direction and the row direction on the lower floor plate; and an upper floor plate 36 placed on the upper cylindrical body arrangement. A center of each cylindrical body 33a constituting the lower cylindrical body arrangement and a center of each cylindrical body 35a constituting the upper cylindrical body arrangement become a positional relationship displaced in the line direction or the row direction. The bottom plate of the inner tank is placed on the upper floor plate.SELECTED DRAWING: Figure 8
【課題】内槽底部支持構造の断熱性能を大幅に改善した大型の二重殻円筒形液体水素タンクを提供する。【解決手段】二重殻円筒形液体水素タンクは、内槽と、外槽と、外槽の底板と内槽の底板との間に設けられる内槽底部支持構造３０とを備える。内槽と外槽との間の空間は真空に保たれる。内槽底部支持構造は、外槽の底板上に同じ高さの複数個の筒状体３３ａを行方向及び列方向に並べて載置した下部筒状体配列３３と、下部筒状体配列上に載置した下部敷板３４と、下部敷板上に同じ高さの複数個の筒状体３５ａを行方向及び列方向に並べて載置した上部筒状体配列３５と、上部筒状体配列上に載置した上部敷板３６とを備える。下部筒状体配列を構成する各筒状体３３ａの中心と、上部筒状体配列を構成する各筒状体３５ａの中心とは、行方向又は列方向にずれた位置関係となっている。内槽の底板は上部敷板上に載置される。【選択図】図８
