The invention discloses an anti-salt-spray-corrosion double-layer-pipe dry air ventilation system, and belongs to the technical field of ships, an exhaust pipe is arranged in a safety area of a power chamber, an exhaust fan can exhaust air in a double-layer pipe to a safety area outside a cabin, a service air compressor is arranged in the power chamber, the service air compressor is connected with an air bottle, and the air bottle is connected with the exhaust fan. The air bottle is connected with a compressed air pipeline, and an oil filter, a dust filter and an air dryer are arranged on the compressed air pipeline. Proper demisting and filtering are carried out on cabin ventilation, meanwhile, the characteristic that the cabin ventilation temperature is high is effectively utilized, corrosion of an air pipe of the cabin is reduced, corrosion of a double-layer pipe is prevented, energy consumption of an outer pipe heater is reduced, the function of a service air compressor is combined, and the service life of the air compressor is prolonged. When a main engine stops, the double-layer pipe can still be effectively ventilated, the equipment cost is reduced, salt spray corrosion of the low-flash-point fuel double-layer pipe is effectively prevented, the ship safety is guaranteed, and the service life of the double-layer pipe is prolonged.
本发明公开了一种防盐雾腐蚀的双层管干燥空气通风系统,属于船舶技术领域,动力室的安全区域设置有排风管,排风风机能够将双层管内的空气排向机舱外的安全区域,动力室内设有服务空压机,服务空压机连接有空气瓶,空气瓶连接有压缩空气管路,压缩空气管路上设有油滤器、粉尘滤器、空气干燥器。本发明中通过对机舱通风进行了适当的除雾过滤,同时有效利用了机舱通风温度高的特点,既降低了机舱的风管腐蚀,又阻止了双层管的腐蚀,而且降低了外管加热器的能量消耗,通过兼用了服务空压机的功能,在主机停止时仍可以对双层管进行有效通风,降低了设备成本,有效阻止了低闪点燃料双层管的盐雾腐蚀,保证了船舶安全,提高了双层管的使用寿命。
