【摘要】：搭建了全尺寸模拟喷漆室灭火试验平台,以清漆为试验燃料,分别在无障碍物和有障碍物两种情况下进行了水喷淋、泡沫和细水雾3种灭火系统的灭清漆池火试验。根据试验中测得的温度、辐射热通量和一氧化碳浓度数据,分析了各系统的灭火效果。试验结果显示,无障碍物时,3种灭火系统均能够实现灭火,水喷淋和细水雾的降温和辐射热阻隔效果要明显优于泡沫灭火系统,细水雾灭火系统的洗消烟气效果则明显优于其他二者;有障碍物时,3种灭火系统只能实现抑火,不能灭火,3种灭火系统的降温和辐射热阻隔效果相似,细水雾灭火系统的洗消烟气效果同样明显优于其他二者。细水雾灭火系统的整体灭火效果更好,更适合在喷漆室场所使用。
[Abstract]:The full-scale simulated spray chamber fire extinguishing test platform was set up. The varnish was used as the test fuel and the water spray foam and water mist systems were used to extinguish the varnish pool fire under the two conditions of no obstacle and obstacle respectively. Based on the experimental data of temperature, radiant heat flux and carbon monoxide concentration, the fire extinguishing effect of each system is analyzed. The experimental results show that without obstacles, all three fire extinguishing systems can put out fire, and the cooling and radiation thermal barrier effects of water spray and fine water mist are obviously better than that of foam fire extinguishing system. The smoke removal effect of water mist fire extinguishing system is obviously better than that of the other two systems. When there are obstacles, three kinds of fire extinguishing systems can only restrain fire, but can not extinguish fire. The cooling and radiation thermal barrier effects of three kinds of fire extinguishing systems are similar, and the effect of washing off flue gas by water mist extinguishing system is obviously better than that of the other two systems. The water mist fire extinguishing system has better fire fighting effect and is more suitable for use in spray room.
