Description
본 발명은 용융염을 통해 저장한 열에너지를 외부에 누출을 최소하하여 보관하는 용기에 관한 것으로, 보다 상세하게는 용융염을 저장하기 위한 스테인레스 스틸 재질의 용기를 이중으로 구성하고 내부 용기와 내부 용기의 접촉을 최소화도록 구성된 저장 용기의 구조에 관한 것이다.The present invention relates to a container that stores thermal energy stored through molten salt with minimal leakage to the outside. More specifically, it consists of a double container made of stainless steel for storing molten salt, and includes an inner container and an inner container. It relates to the structure of a storage container configured to minimize contact.
일반적으로 진공 이중 저장 용기를 만들 때에는 외부 용기와 내부 용기가 상부의 용기 입구부분에 이어지게 된다. 이는 내부와 외부의 용기가 일체형으로 되어 있으면서 용기 사이의 진공을 구성하여 대류를 통한 열의 이동을 최소화하기 위한 것이다. 그러나 이와 같은 형태는 상부의 연결된 부분으로 전도를 통한 열의 이동이 발생하게 되며 내부 용기의 가열로 인한 외부 용기로 복사 열에너지 전달이 일어나게 된다.Generally, when making a vacuum double storage container, the outer container and the inner container are connected to the entrance of the upper container. This is to minimize the movement of heat through convection by creating a vacuum between the inner and outer containers while being integrated. However, in this type, heat transfer occurs through conduction to the upper connected part, and radiant heat energy is transferred to the external container due to heating of the inner container.
본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 내부 용기와 내부 용기간의 전도, 대류, 복사를 통한 열에너지 전달을 최소화하도록 구성된 이중 저장 용기의 구조를 제공하는 것을 그 목적으로 한다.The present invention is intended to solve the above problems, and its purpose is to provide a structure of a dual storage container configured to minimize heat energy transfer through conduction, convection, and radiation between the inner container and the inner container.
또한, 내부의 보관되어 있는 염을 녹이는 과정에서 유도전류를 사용하는 과정에서의 접점을 통한 열에너지 방출이 최소화된 구조를 제공하는 것을 그 목적으로 한다.In addition, the purpose is to provide a structure that minimizes the release of heat energy through contact points in the process of using induced current in the process of melting the salt stored inside.
이와 같은 목적을 달성하기 위해 본 고안은, 이중 용기를 형성하기 위한 크기가 서로 다른 한쌍의 스테인레스 스틸 용기가 외부 용기와 내부 용기의 사이에 수개의 세라믹 지지대를 통해 구분되어 있으며; 상단부의 외부 용기와 내부 용기의 이음부분은 세라믹 링의 형태로 구성하여 구분하고; 내부 용기내에 위치한 유도전류 관로의 개폐부를 세라믹 덮개로 구성하여 열이동을 최소화 할 수 있도록 이루어진 것을 특징으로 한다In order to achieve this purpose, the present invention includes a pair of stainless steel containers of different sizes to form a double container, separated between the outer container and the inner container by several ceramic supports; The joint between the outer container and the inner container at the top is divided into a ceramic ring shape; It is characterized in that the opening and closing part of the induced current pipe located in the internal container is made of a ceramic cover to minimize heat transfer.
본 발명에 따른 용융염 저장용 이중 용기에 의하면 내부용기와 외부 용기가 최소한의 세라믹 지지대를 통하여 분리되어 전도가 최소화되고 용기 사이에 진공을 형성하여 대류를 최소화하며 외부용기의 안쪽에 매끄러운 반사면으로 구성되어 복사를 최소화하여 열의 이동을 효과적으로 차단 하는 효과가 있다.According to the dual container for storing molten salt according to the present invention, the inner container and the outer container are separated through a minimum ceramic support to minimize conduction, form a vacuum between the containers to minimize convection, and have a smooth reflective surface on the inside of the outer container. It has the effect of effectively blocking the movement of heat by minimizing radiation.
