摘要
采用FDS(fire dynamic simulation)数值模拟软件对地下污水处理厂典型区域(大空间及十字廊道)进行了火灾模拟研究。通过在不同位置设置不同火灾功率的火源,研究了烟气温度、烟气运动、烟气浓度、能见度等因素随时间的变化。分析了不同工况下火灾对人员逃生的影响,为地下污水处理厂典型空间的消防设计提供依据。
The FDS(fire dynamic simulation)numerical simulation software is used to simulate the fire in the typical areas(large spaces and cross corridors)of underground sewage treatment plants.By setting the fire source of different fire power in different locations,the change of flue gas temperature,flue gas movement,flue gas concentration,visibility and other factors with time is studied.The impact of fire on personnel escape under different working conditions is analysed,which provides a basis for the fire protection design of typical space of underground sewage treatment plants.
