The invention relates to the technical field of ocean engineering, in particular to a ventilation system for an expansion cabin of a ship oil-water replacement system, which comprises a ventilation pipe communicated with the expansion cabin, penetrating through a freeboard deck and used for keeping the pressure in the expansion cabin consistent with the atmospheric pressure; the liquid tank air pipe head is arranged at the end, away from the expansion cabin, of the vent pipe and used for preventing outboard water from flowing into the vent pipe. The buffer tank is arranged on the vent pipe in a communicating manner and is used for providing a buffer space for overflowing seawater; the overflow pipe is communicated with the upper part of the buffer tank, and one end far away from the buffer tank is connected with the outboard space; and the stop valve is arranged on the vent pipe, is positioned between the buffer tank and the expansion cabin, and is used for controlling the switching of open replacement and closed replacement of the oil-water replacement system. According to the ventilation system, ventilation of the expansion cabin can be achieved, overflowing seawater cannot overflow out of the ventilation pipe, stable back pressure control during seawater overflowing can be guaranteed, and the ventilation system has the ventilation function, the overflowing function and the pressure stabilizing function.
本申请涉及海洋工程技术领域,尤其涉及一种用于船舶油水代换系统膨胀舱的透气系统,其包括:透气管,与膨胀舱连通并贯穿干舷甲板设置,用于保持膨胀舱舱内压力与大气压力一致;液舱空气管头,设置在透气管远离膨胀舱的一端,用于防止舷外水涌入透气管;缓冲罐,连通设置在透气管上,用于为溢处海水提供缓冲空间;溢流管,连通设置在缓冲罐上部,且远离缓冲罐的一端与舷外空间连接;以及截止阀,设置在透气管上并位于缓冲罐与膨胀舱之间,用于控制油水代换系统开式代换和闭式代换的切换。本申请的透气系统,既能实现膨胀舱的透气,且溢流的海水不会从透气管中漫出,又能保障海水溢流时稳定的背压控制,兼具透气、溢流、稳压功能。
