The invention discloses a methanol dual-fuel ship double-wall pipe purging residual liquid recovery system and method. The system is provided with a purging unit, a connecting pipeline of the purging unit is connected with an outer pipe and an inner pipe of each double-wall pipe, nitrogen inlets are formed in ports of the inner pipe and the outer pipe of each double-wall pipe, and residual methanol gas and/or residual liquid in the inner pipe and the outer pipe are purged into a methanol daily cabin according to the flow direction of methanol fuel. And recycling is carried out. The methanol gas and residual liquid are collected, daily maintenance is facilitated, and damage to pipelines caused by residual methanol liquid/gas is reduced.

    本发明公开了一种甲醇双燃料船双壁管吹扫残液回收系统及方法。该系统设有吹扫单元,吹扫单元的连接管路连接各个双壁管的外管和内管,并在各个双壁管的内管的和外管的端口处设置氮气进口,以甲醇燃料的流向作为依据将内管和外管内残存的甲醇气体和/或残液吹扫进甲醇日用舱中,进行回收利用。本发明对甲醇气体及残液进行收集、方便日常的维护、减少甲醇液体/气体残存对管路造成的损害。
