The invention discloses a method for detecting ventilation safety of a methanol dual-fuel container ship dangerous area picture, and relates to the technical field of ship safety monitoring, and the method comprises the following steps: installing a differential pressure gauge in a fuel cabin connecting chamber and an air lock chamber respectively, and connecting two pipelines of the differential pressure gauges to the fuel cabin connecting chamber and the air lock chamber respectively; if the fan in the fuel cabin connecting chamber operates normally and the differential pressure signal of the differential pressure gauge is within a preset range, judging that the fuel cabin connecting chamber is in a'safe ventilation state '; and if the fan in the fuel cabin connecting chamber operates normally, but the differential pressure signal of the differential pressure gauge is smaller than a preset range, judging that the differential pressure gauge fails or the fuel cabin connecting chamber is in an unsafe ventilation state. By simultaneously monitoring the running state of the fan and the differential pressure signal of the differential pressure gauge, the effect of quickly checking whether the fuel cabin connecting chamber and the air lock chamber are in the ventilation safety state or not is achieved.
本发明公开了一种检测甲醇双燃料集装箱船舶危险区画通风安全的方法,涉及船舶安全监测技术领域,包括如下步骤,在燃料舱室连接室和气闸室内各安装一个压差计,压差计的两个管路分别连接至燃料舱室连接室和气闸室;若燃料舱室连接室内的风机正常运行,并且压差计的压差信号在预设范围内,则判定燃料舱室连接室处于“安全通风状态”;若燃料舱室连接室内的风机正常运行,但压差计的压差信号小于预设范围,则判断压差计故障或燃料舱室连接室处于“非安全通风状态”。可以通过同时监测风机的运行状态和压差计的差压信号,达到了快速检验燃料舱室连接室和气闸室是否处于通风安全状态的效果。
