The invention discloses a ventilation system of a B-type LNG (Liquefied Natural Gas) fuel cabin space, which comprises a gas leakage detector and a pressure sensor, and the gas leakage detector and the pressure sensor are arranged in the space formed between an LNG fuel cabin and an outer cabin wall. An exhaust pipeline communicated with the inner side and the outer side of the outer-layer cabin wall penetrates through the outer-layer cabin wall and is connected with the outer-layer cabin wall in a sealed mode, an airtight electric butterfly valve used for opening and closing a channel between the space reserving position and the external atmosphere is arranged on the exhaust pipeline, and an anti-explosion exhaust fan is arranged on the side, connected with the external atmosphere, of the airtight electric butterfly valve. The anti-explosion exhaust fan, the airtight electric butterfly valve, the gas leakage detector and the pressure sensor are electrically connected with the PLC control module. The ventilation system is compact in structure and convenient to install, meanwhile, the ventilation system is provided with the PLC control module, and the ventilation requirements of the vacant space in different states can be met according to gas detection and pressure sensing of the vacant space and automatic adjustment of the anti-explosion exhaust fan and the airtight electric butterfly valve.
本发明公开了一种B型LNG燃料舱空留处所的通风系统,包括气体泄漏探测器和压力传感器,气体泄漏探测器和压力传感器均设于设于LNG燃料舱和外层舱壁之间的形成的空留处所内,外层舱壁上贯穿且密封连接有连通外层舱壁内外侧的排风管路,排风管路上设有开关空留处所与外界大气之间通路的气密电动蝶阀,气密电动蝶阀与外界大气连接的一侧设有防爆排风机,防爆排风机、气密电动蝶阀、气体泄漏探测器和压力传感器分别与PLC控制模块电连接。本发明提供的通风系统结构紧凑,安装方便,同时自带PLC控制模块,可根据空留处所的气体探测和压力传感,防爆排风机和气密电动蝶阀的自动调节,满足空留处所的不同状态下的通风要求。
