The invention provides a large container ship methanol fuel preparation room ventilation system which comprises a fresh air pipe system, an exhaust pipe system, a fire extinguishing system, a methanol gas detection system, a control platform and a double-wall pipe waterproof ventilation system, and the fresh air pipe system, the exhaust pipe system, the fire extinguishing system and the methanol gas detection system are all connected with the control platform; if leaked methanol steam is detected, the methanol steam sensor sends a leakage signal to the control platform, and the control platform sends a signal to respectively open and close an air brake, an air inlet shutter and an anti-explosion exhaust fan; and if open fire is detected, the fire alarm probe sends a fire alarm signal to the control platform, the control platform sends out signals respectively, the shut-off air brake, the air inlet shutter and the anti-explosion exhaust fan are closed respectively, and an alcohol-resistant foam fire extinguishing unit of the fire extinguishing system is started. The fireproof, explosion-proof and ventilation performance of the methanol fuel preparation room is further improved, the operation risk of sailors is reduced, and potential safety hazards brought by methanol to the sailors are avoided.

    本发明提供了一种大型集装箱船舶甲醇燃料准备间通风系统,包括新风管系统、排风管系统、灭火系统、甲醇气体探测系统、控制平台和双壁管防水通风系统,新风管系统、排风管系统、灭火系统、甲醇气体探测系统均与控制平台相连;若检测到泄漏的甲醇蒸汽,甲醇蒸汽传感器将泄漏信号发送至控制平台,控制平台发出信号,分别打开关断风闸、进风百叶窗和防爆排风机;若检测到发生明火,火警探头将火警信号发送至控制平台,控制平台分别发出信号,分别关闭关断风闸、进风百叶窗和防爆排风机,启动灭火系统的抗醇泡沫灭火单元。使用本发明进一步提高了甲醇燃料准备间防火、防爆及通风性能,降低了船员的操作风险,避免了甲醇给船员带来的安全隐患。
