The invention discloses a liquid hydrogen heat preservation enclosure system which comprises an independent liquid cargo tank which is of a double-layer shell structure with an inner shell and an outer shell. A vacuum heat insulating layer is arranged between the inner shell and the outer shell; the outer wall of the shell is coated with a heat preservation layer. The outer wall of the heat preservation layer is coated with a waterproof layer; a plurality of longitudinal strong frames and a plurality of transverse strong frames are fixedly connected to the outer wall of the shell; supporting cushion blocks are arranged between the longitudinal strong frame and the ship body structure and between the transverse strong frame and the ship body structure. The liquid cargo tank has larger tank capacity and good heat insulation performance; and after the main shield leaks, a water curtain can be automatically formed to protect the ship body and prevent low-temperature damage.
本发明公开了一种液氢保温围护系统,其包括独立液货舱,独立液货舱为具有内壳和外壳的双层壳体结构;内壳和外壳之间为真空绝热层;外壳的外壁包覆有保温层;保温层的外壁包覆有防水层;外壳的外壁上固接有若干纵向强框和若干横向强框;纵向强框与船体结构之间、横向强框与船体结构之间设有支撑垫块。本发明的液货舱具有更大的舱容,绝热性能好;还能在主屏蔽泄漏后,自动形成水幕,保护船体,防止低温损害。
