| 摘 要： | 利用气泡雾化压力低、用气量小和雾化效果好的特点,结合目前已有的移动细水雾灭火装备开发了一套背负式气泡雾化细水雾灭火装备.对木垛火进行灭火实验,分析了细水雾灭火过程中不同阶段的主导灭火机理.实验结果表明:利用气泡雾化细水雾灭火装备可有效控制和扑救木垛火,对于0.6A以下的木垛火,可在150 s内扑灭,0.8A的木垛则出现了复燃现象,由于木条的相互遮挡,对于木垛火的扑救应灵活调整射水距离和角度,压制火焰,预防复燃.

| Abstract: | Combining with the characteristics of effervescent atomization and knapsack water mist fire fighting equipment,a water mist fire extinguishing equipment was developed. A series of wood crib fire suppression experiments were performed using the equipment. According to the process of putting out,the dominant mechanism of extinguishment with water mist was analyzed. A wood crib fire under 0. 6A can be put out in 150 seconds. For 0. 8A wood crib fire,it cannot succeed by effervescent atomization water mist equipment. |
