The invention discloses a safe anti-explosion ventilation system of a methanol fuel ship. The system comprises a methanol storage cabin, a methanol discharge cabin and a ventilation pipeline system. The ventilation pipeline system passes through a transverse compartment for isolating the void compartment and the cargo compartment and a binding bridge, the ventilation pipeline system comprises ventilation branch pipes and ventilation main pipes, each compartment is communicated with two ventilation branch pipes, and the two ventilation branch pipes of each compartment are respectively provided with a pressure vacuum valve and are connected to the left ventilation main pipe and the right ventilation main pipe; the ventilation header pipe extends to the position of the transverse compartment through the left side and the right side in the pump compartment and continues to be arranged upwards to the left gunwale and the right gunwale of the topmost layer of the binding bridge above the transverse compartment, a flame arrester is installed at an outlet, a horizontal pipeline of the ventilation header pipe is arranged in an inclined mode, and the lowest point of the ventilation header pipe is connected with a discharging pipeline. After the vent pipes are combined and arranged, the occupied space is small, pipes are reduced, and meanwhile the influence of emission of methanol gas is reduced.

    本发明公开了一种甲醇燃料船安全防爆透气系统。该系统包括甲醇储存舱、甲醇泄放舱和透气管路系统。透气管路系统经过隔离空舱、货舱的横隔舱和绑扎桥,透气管路系统包括透气支管和透气总管,每个舱室接通有两根透气支管,每个舱室的两根透气支管分别安装压力真空阀并连接到左右两根透气总管,透气总管分别通过泵舱内部的左右两边延伸到横隔舱位置并继续向上布置到横隔舱上方绑扎桥最顶层的左右两舷边,出口安装阻火器,透气总管的水平管路布置有斜度,透气总管的最低点连接有泄放管路。本发明将透气管合并布置后占用空间小、减少管材、同时降低甲醇气体的排放的影响。
