According to the present invention, the insulation system of a membrane-type storage tank comprises: a second insulation wall which is placed to insulate the internal space of the liquefied natural gas storage tank from outside, and which is bent to be placed in a corner of the liquefied natural gas storage tank; a second sealed wall which is piled up on the second insulation wall, and which is made from stainless steel with a wrinkle unit; a first insulation wall which is piled up on the second sealed wall, and which is bent to be combined with the second insulation wall; and a first sealed wall which is piled up on the first insulation wall, and which is made from stainless steel with a wrinkle unit towards the inside of the liquefied natural gas storage tank. A first insulation wall combination means, which is placed on the second insulation wall, is inserted into a combination hole which is placed on the first insulation wall, and the first insulation wall is combined with the second insulation wall. According to the present invention, provided are a structure of an insulation system, which is proper even when the second sealed wall is made from stainless steel in the membrane-type storage tank, and a storage tank comprising the same.
본 발명에 의한 멤브레인형 저장탱크의 단열시스템은, 액화천연가스 저장탱크의 내부 공간을 외부와 단열시키기 위해 마련되고, 액화천연가스 저장탱크의 코너에 마련되도록 절곡된 형태를 갖는 2차 단열벽, 상기 2차 단열벽 상에 적층되고, 주름부를 가지는 스테인리스 강 소재로 마련되는 2차 밀봉벽, 상기 2차 밀봉벽 상에 적층되고, 상기 2차 단열벽과 결합되도록 절곡된 형태를 갖는 1차 단열벽 및 상기 1차 단열벽 상에 적층 마련되고, 액화천연가스 저장탱크의 내측 방향으로 주름부가 형성된 스테인리스 강 소재의 1차 밀봉벽을 포함하고, 상기 2차 단열벽 상에 마련되는 1차 단열벽 결합수단이 상기 1차 단열벽에 마련되는 결합홀에 끼워짐으로써, 상기 1차 단열벽이 상기 2차 단열벽에 결합되는 것을 특징으로 함으로써, 본 발명에 의하면, 멤브레인 타입의 저장탱크에서 2차 밀봉벽이 스테인리스 강으로 형성되는 경우에도 적합한 단열시스템의 구조와 이를 포함하는 저장탱크가 제공된다.
