본 발명은 에어로젤을 이용한 LNG 운반선의 절연 구조에 관한 것이다. 더욱 상세하게는 LNG 운반선의 절연 구조를 단순화하고, 화물창의 적재 용량을 극대화할 수 있는 LNG 운반선의 절연 구조에 관한 것이다.The present invention relates to an insulation structure of an LNG carrier using an airgel. More particularly, the present invention relates to an insulation structure of an LNG carrier that can simplify an insulation structure of an LNG carrier and maximize a load capacity of a cargo hold.

일반적으로, 액화천연가스(Liquefied Natural Gas, 이하: LNG)는 지하에서 뽑아 올린 탄화수소 계열의 천연가스를 운송과 저장의 편의를 위해 영하 162℃로 압축, 냉각, 액화시켜 부피를 1/600으로 줄인 극저온의 액체를 말한다. 이는 가격에 비해 열량이 우수하여 석유 대체에너지로 각광받고 있으며, 청정에너지로서 교역량이 증가됨에 따라 LNG 운반선의 수요도 증가하고 있다.In general, liquefied natural gas (Liquefied Natural Gas) is compressed, cooled, and liquefied to below 162 ° C to reduce the volume to 1/600. It is a cryogenic liquid. It has a high calorie value compared to the price, and is being spotlighted as an alternative to petroleum. As the trade volume is increased as clean energy, the demand for LNG carriers is increasing.

이와 같은 액화천연가스 또는 액화수소 및 산소 등 저온의 액화가스를 저장 수송하는 단열용기의 설계에 있어서 외부로부터의 열 침입에 의한 액화가스의 비등을 방지하는 단열 기술이 무엇보다도 중요하다.In the design of such a thermal insulation container for storing and transporting such liquefied natural gas or low temperature liquefied gas such as liquefied hydrogen and oxygen, a heat insulation technology for preventing boiling of liquefied gas due to heat intrusion from the outside is important.

현재 상업적으로 개발되어 적용되고 있는 단열방법에는 외부 단열 방법과 내부 단열방법이 있으며, 내부 단열방법은 용기 외함의 온도를 외기 온도와 유사하게 제어할 수 있으므로 저온용 소재의 적용과 같은 소재 사용에 제약이 없는 장점을 구비하고 있다.Currently, commercially developed and applied insulation methods include external insulation methods and internal insulation methods, and the internal insulation method can control the temperature of a container's enclosure similar to the air temperature, thus limiting the use of materials such as the application of low-temperature materials. It has no advantages.

이러한 내부 단열방법에는 미국의 맥도널 더글라스사의 중간 방벽 구조(US 3,993,216, 1976)를 기초로 2중 방벽 구조를 가지는 프랑스의 GTT사의 멤브레인형의 단열 용기가 알려져 있다.In the internal insulation method, a membrane-type insulation container of GTT, France, which has a double barrier structure based on the middle barrier structure (US 3,993,216, 1976) of McDonald Douglas, USA is known.

특히, LNG를 운반하는 LNG 운반선은 LNG의 특성 때문에 단열탱크의 형식 및 성능이 중요하며, LNG화물이 적재되는 단열탱크의 형식에 따라 구형(독립형)과 멤브레인(membrane)형으로 나누어진다.In particular, LNG carriers carrying LNG are important in form and performance of the insulation tank because of the characteristics of LNG, and is divided into spherical (independent) and membrane (membrane) type according to the type of the insulation tank to which LNG cargo is loaded.

현재 멤브레인 형태의 LNG 운반선에 적용하는 단열 구조는 폴리우레탄 폼(PUF)이나 퍼라이트 박스(perite box) 등 다양한 형태의 절연 구조로 사용되나, 제작 및 설치 작업이 복잡하고 설치 시수가 많이 발생 되는 문제점이 있었다.Currently, the insulation structure applied to LNG carriers in the form of membrane is used in various types of insulation structures such as polyurethane foam (PUF) or perite box, but the manufacturing and installation work is complicated and the installation time is frequently generated. there was.

즉, 기존의 1차 및 2차 방벽으로서 같은 형태의 폴리우레탄 폼(PUF)이나 퍼라이트 박스(perite box)를 사용하여 단열층의 절연 구조를 단순화할 수 없으며, 화물창의 적재 용량의 손실을 줄일 수 없었다.That is, using the same type of polyurethane foam (PUF) or perite box as the primary and secondary barriers, the insulation structure of the insulation layer cannot be simplified, and the loss of loading capacity of the cargo hold cannot be reduced. .

이에, 본 발명은 상기한 문제점을 해결하기 위한 것으로서 본 발명의 목적은 LNG 운반선의 절연 구조를 단순화하고, 화물창의 적재 용량을 극대화할 수 있도록 에어로젤 패드와 에어로젤 비드 또는 분말을 이용한 LNG 운반선의 절연 구조를 제공하는 데 있다.Accordingly, the present invention is to solve the above problems, an object of the present invention is to simplify the insulation structure of the LNG carrier, and to insulate the structure of the LNG carrier using an airgel pad and airgel beads or powder to maximize the loading capacity of the cargo hold. To provide.

It is installed.

또한, 상기 제 1금속패널(10)과 제 2금속패널(16) 사이에 에어로젤이 함유된 패드, 즉 에어로젤 패드(aerogel pad)(14)가 형성되는 데, 상기 에어로젤(Aerogel)은 나노단위의 기공성 구조를 가진 저밀도 물질이며 열전도도, 음파 전도도가 극히 낮으며, 단열/방음/방진/적외선 차단성 및 충격흡수 특성이 우수하다.In addition, an airgel-containing pad, that is, an aerogel pad 14, is formed between the first metal panel 10 and the second metal panel 16.
