The invention discloses a semi-thin film type enclosure system for low-temperature liquefied gas storage, which comprises strong structure nodes (001) fixed on the surface of a cargo hold inner shell structure in a dot matrix manner, and metal plate strip beams which are connected longitudinally and transversely are arranged on the top surfaces of the strong structure vertexes to form a framework (112) of a grid structure; a liquid-tight first screen wall layer (111) is anchored on the frame by welding; a first insulating layer is arranged on the outer side of the first screen wall layer; a second screen wall layer (211) is arranged on the outer side of the first insulating layer, and a second insulating layer is arranged between the outer side of the second screen wall layer and the surface of the cargo hold inner shell structure; the first screen wall layer and the second screen wall layer are metal sheets with protruding corrugations. The method solves the technical problems that the secondary screen wall layer of an existing film storage tank completely depends on glue for adhesion, the construction difficulty is high, and later maintenance is difficult. Particularly, the problem of lashing caused by free liquid level sloshing of the storage tank in the sailing process is solved.

    本发明公开了一种用于低温液化气体储存的半薄膜型围护系统,包括以点阵方式固定在货舱内壳结构表面上的强结构节点(001),所述强结构顶点的顶面设置有纵横连接金属板条梁,构成网格结构的框架(112);液密的第一屏壁层(111)通过焊接锚固在所述框架上;所述第一屏壁层外侧设置了第一绝缘层;所述第一绝缘层的外侧设置了第二屏壁层(211),所述第二屏壁层外侧与货舱内壳结构表面之间设置了第二绝缘层;所述第一屏壁层和所述第二屏壁层为带有凸起波纹的金属薄板。本发明解决了对现有薄膜储罐次屏壁层完全依靠胶水粘连、施工难度高、后期维护困难的工艺难点。尤其解决了航行过程中储舱自由液面晃荡产生的抨击问题。
