Zusammenfassung: | A pressure regulating device for an LNG tank is disclosed. The pressure regulating device according to an embodiment of the present invention comprises: an LNG tank; an LNG supply line that provides the LNG of the LNG tank to a consumer; a spray line that is located on the upper part of the inside of the LNG tank and is equipped with a spray nozzle; an LNG supply branch line in which one end is branched from the LNG supply line and the other end is connected to the spray line to provide the LNG to the LNG supply line; and a pre-cooling line that is branched from the LNG supply branch line at one end and is located adjacent to the bottom of the LNG tank at the other end, and pre-cools the LNG supply branch line during initial operation of the spray line, thereby improving efficiency and reliability.
엘엔지 탱크의 압력조절장치가 개시된다. 본 발명의 실시 예에 따른 압력조절장치는 엘엔지 탱크와, 엘엔지 탱크의 엘엔지를 수요처로 제공하는 엘엔지 공급라인과, 엘엔지 탱크 내부 상부쪽에 위치되며 스프레이 노즐이 설치된 스프레이 라인과, 엘엔지 공급라인에 엘엔지를 제공하도록 일단이 엘엔지 공급라인에서 분기되며 타단이 스프레이 라인에 연결되는 엘엔지 공급 분기라인 및 일단이 엘엔지 공급 분기라인에서 분기되며 타단이 엘엔지 탱크의 바닥과 인접하게 위치되고, 스프레이 라인의 초기 가동 시 엘엔지 공급 분기라인을 예냉시키는 예냉라인을 포함한다. |
