The invention discloses a ventilation system for a fuel oil and methanol dual-purpose cabin of a dual-fuel bulk carrier. The ventilation system of the fuel oil and methanol dual-purpose cabin of the dual-fuel bulk carrier comprises a dual-purpose cabin installed in a void cabin, at least one fuel oil ventilation pipe is arranged at the top of the dual-purpose cabin, an air pipe head is arranged at the top, penetrating out of the void cabin and a deck, of the fuel oil ventilation pipe, a first on-off piece is arranged on the fuel oil ventilation pipe and used for controlling on-off of the fuel oil ventilation pipe, and a second on-off piece is arranged on the deck and used for controlling on-off of the fuel oil ventilation pipe. The fuel vent pipe is communicated with an intercommunication vent pipe between the first on-off piece and the dual-purpose cabin, the intercommunication vent pipe is communicated with a methanol vent branch pipe, the methanol vent branch pipe is communicated with a methanol vent header pipe, the methanol vent header pipe is laid to a vent mast, and a pressure vacuum valve is arranged on the methanol vent branch pipe; and a second on-off piece is arranged on the intercommunication vent pipe between the methanol vent branch pipe and the fuel vent pipe, and is used for controlling the on-off of the intercommunication vent pipe. The problem that the prior art cannot be applied to the dual-purpose cabin is solved.

    本发明公开了一种双燃料散货船燃油甲醇兼用舱透气系统。该双燃料散货船燃油甲醇兼用舱透气系统包括安装于空舱内部的兼用舱,所述兼用舱的顶部至少设置有一个燃油透气管,燃油透气管穿出空舱和甲板的顶部设置有空气管头,燃油透气管上设置有第一通断件,用于控制燃油透气管的通断,燃油透气管位于第一通断件和兼用舱之间连通有互通透气管,互通透气管连通有甲醇透气支管,甲醇透气支管连通有甲醇透气总管,甲醇透气总管敷设至透气桅,甲醇透气支管上设置有压力真空阀,互通透气管位于甲醇透气支管和燃油透气管之间设置有第二通断件,用于控制互通透气管的通断。本发明解决了现有技术无法适用兼用舱的问题。
