The invention discloses a methanol lightering system of a methanol fuel ship, which comprises a methanol storage cabin, a methanol daily cabin, a vent pipe, a three-way joint, a return pipe and a methanol lightering pipe, the methanol daily cabin is arranged below the methanol storage cabin, one end of the vent pipe is connected with a vent hole at the upper end of the methanol storage cabin, and the other end of the vent pipe is connected with the three-way joint; one end of the ventilation pipe is connected with a first port of the three-way connector, one end of the backflow pipe is connected with a second port of the three-way connector, the other end of the backflow pipe is connected with a backflow port in the upper end of the methanol daily cabin, and one end of the methanol lightering pipe is connected with a lightering port in the lower end of the side face of the methanol storage cabin; the other end of the methanol lightering pipe is connected with a third port of a three-way joint; and the three-way joint is positioned on the upper side of the highest liquid level of the methanol storage cabin. Through the reasonable pipeline design, the problem of methanol flowing after the methanol lightering pump stops due to the siphon principle is solved, and the design cost is reduced on the whole.

    本发明公开了一种甲醇燃料船的甲醇驳运系统,包含甲醇存储舱、甲醇日用舱、透气管、三通接头、回流管和甲醇驳运管,甲醇日用舱设置在甲醇存储舱下方,透气管的一端与甲醇存储舱上端透气口连接,透气管的另一端与三通接头的第一端口连接,回流管的一端与三通接头的第二端口连接,回流管的另一端与甲醇日用舱上端回流口连接,甲醇驳运管的一端与甲醇存储舱侧面下端驳运口连接,甲醇驳运管的另一端与三通接头的第三端口连接,三通接头位于甲醇存储舱最高液位上侧。本发明通过合理的管路设计,解决了虹吸原理引起的甲醇驳运泵停止后甲醇的流动问题,并且整体上降低了设计成本。
