The invention discloses a construction ventilation system in a film type LNG (Liquefied Natural Gas) cabin, which comprises a dehumidification unit, an air supply system, an air return system, a smoke ventilator, a first fireproof valve, a second fireproof valve, a smoke sensor, an automatic water spraying fire extinguishing device, an automatic control shutter, a silencer, super glass wool and a central controller, the air supply system comprises a tenth-layer air supply branch pipe, a ninth-layer air supply branch pipe and a plurality of air supply branch pipes vertically extending to the fourth layer of the cabin, wherein the tenth-layer air supply branch pipe and the ninth-layer air supply branch pipe are arranged at the top of the cabin. The air return system comprises a third-layer air return pipeline which is connected into the cabin along the elevator shaft and extends to the lower portion of the cabin. According to the ventilation system, middle-upper-portion air supply and lower-portion air exhaust are achieved, and the problem of ventilation dead angles is solved; and the central controller is used for controlling, so that an automatic fire control effect is achieved.

    本发明公开了一种薄膜型LNG船舱内施工通风系统,包括除湿机组、送风系统、回风系统、排烟机、第一防火阀、第二防火阀、烟雾传感器、自动喷水灭火装置、自动控制百叶窗、消音器、超级玻璃棉和中央控制器,所述除湿机组设置在液货舱顶部甲板上方,所述送风系统包括设置在舱室顶部的第十层送风支管、第九层送风支管和多个垂向延伸至舱室第四层的送风支管,所述回风系统包括沿着电梯井接进舱内直至舱室下部的第三层回风管道。本发明实现了中上部送风和下部排风的通风系统,解决存在通风死角的问题;且由中央控制器进行控制,达到自动消防控制效果。
