The present invention provides a pump tower of a liquefied gas storage tank including a filling pipe of a dual-pipe structure which improves insulation performance in comparison to a conventional technique and simplifies the complex structure around a dome to promote productivity improvement and cost reduction. The pump tower of a liquefied gas storage tank includes a filling pipe allowing liquefied gas to flow into a liquefied gas storage tank from the outside and playing a role of a structural member for a load by fixing the lower end thereof on a base support installed on the bottom of the liquefied gas storage tank. The diameter of the filling pipe is designed to be larger than a fluid flow capacity to play the role of a structural member and the filling pipe has a dual-pipe structure including an inner pipe in the filling pipe. The inner pipe includes: an inlet forming an inflow path separate from the inflow path of liquefied gas through the filling pipe; and a discharge pipe formed on the lower end of the inner pipe and penetrating a side of the filling pipe to communicate with the inside of the liquefied gas storage tank. The discharge pipe supplies liquefied gas flowing into the inlet into the liquefied gas storage tank by top filling or spraying.
본 발명은, 외부로부터 액화가스 저장탱크 내부로 액화가스를 유입시키되 하단부가 액화가스 저장탱크의 바닥에 설치되는 베이스 서포트에 고정되어 하중에 대한 구조부재 역할을 하는 충전용 파이프를 포함하고, 상기 충전용 파이프는 구조부재 역할을 하기 위하여 직경이 유체 유동 용량보다 크게 설계되되 내부에 내부관을 포함하는 이중배관 구조로 마련되며, 상기 내부관은 충전용 파이프를 통한 액화가스의 유입경로와 별도의 유입경로를 형성하는 유입구; 및 내부관의 하단에 형성되며 충전용 파이프의 측면을 관통하여 액화가스 저장탱크의 내부와 연통되는 배출관을 포함하고, 상기 배출관은 유입구로 유입된 액화가스를 액화가스 저장탱크 내부로 탑 필링(top filling)하는 방식 또는 분사(spraying)하는 방식으로 공급하는 것을 특징으로 하는, 이중배관 구조의 충전용 파이프를 포함하는 액화가스 저장탱크의 펌프타워를 제공한다.
