机械通风下细水雾熄灭油池火有效性试验

Experimental study on pool fire extinguishment efficiency with water mist under different mechanical ventilation conditions

对细水雾灭火技术在机械通风作用下熄灭油池火的有效性进行了试验研究。试验中改变机械通风设备的开启时间、变频器频率等,获取不同机械通风条件下油池火的熄灭时间,分析讨论了机械通风对细水雾熄灭油池火的影响。结果表明:当机械通风设备始终处于开启状态、风机转数为1 200r/min时细水雾熄灭油池火的时间最短。

The pool fire extinguishment efficiency under applications of water mist and mechanical ventilation conditions has been experimented.Changed the turn-on time and the transducer frequency of the mechanical ventilation equipment and so on,obtained the fire out time,analyzed the influence of mechanical ventilation on water mist extinguishing the pool fire.The results indicated that the time of water mist extinguishing the pool fire was shortest under the condition of mechanical ventilation kept open and the fan revolution was 1 200r/min.
