The invention relates to a marine methanol fuel supply system which comprises a methanol storage cabin, a heat exchanger, a methanol temporary storage cabin and a methanol isolation cabin, the system further comprises a methanol purging cabin, a three-way valve and a methanol pump; two inlet ends of the three-way valve are respectively connected to the methanol purging cabin and the methanol storage cabin through pipelines; one end of the methanol pump is connected with an outlet of the three-way valve, the other end of the methanol pump is connected with the heat exchanger, and methanol fuel is lighted to the heat exchanger from the methanol storage cabin and the methanol purging cabin; the main machine is provided with a methanol purging pipeline which is used for purging methanol fuel in a pipeline system to the methanol purging cabin after the methanol fuel supply system stops running; and the methanol purging cabin is not provided with an additional discharge channel. The complexity and the construction cost of the methanol fuel supply system are reduced, meanwhile, crew does not need to separate oil dirt in methanol fuel, the workload of the crew is reduced, and the safety of a ship is improved.

    本发明涉及一种船用甲醇燃料供给系统,包括甲醇储存舱、换热器,不设置甲醇暂存舱和甲醇隔离舱;还包括甲醇吹扫舱、三通阀、甲醇泵;三通阀的两个入口端分别通过管路连接至甲醇吹扫舱和甲醇储存舱;甲醇泵一端与三通阀出口连接,另一端与所述换热器连接,将甲醇燃料从甲醇储存舱和甲醇吹扫舱将甲醇驳运到换热器;主机设置有甲醇吹扫管路,用于在甲醇燃料供给系统停止运行后将管路系统内的甲醇燃料吹扫到甲醇吹扫舱;甲醇吹扫舱不设置额外的排泄通道。本发明降低了甲醇燃料供应系统的复杂性以及建造成本,同时无需船员去分离甲醇燃料中的油污,降低了船员的工作负荷,增加了船舶的安全性。
