实验研究了水成膜泡沫灭火剂在燃烧油面的铺展过程。经过实验数据处理和图像采集,分析了泡沫的铺展速度、铺展时间、铺展过程以及实验现象,定性地得到了油面燃烧温度对泡沫铺展过程的影响,以及泡沫在燃烧油面上覆盖灭火时一维方向的速度变化过程,掌握了水成膜泡沫灭火剂在燃烧油面铺展时相关参数的变化情况,深入地了解了泡沫的灭火过程,并丰富了泡沫铺展理论的研究。
Experimental study of water-filming foam fire extinguishing agent in the burning oil surface spreading process. After experimental data processing and image acquisition, the spreading speed, spreading time, spreading process and experimental phenomenon of foam were analyzed. The influence of oil burning temperature on foam spreading process was qualitatively obtained. When the foam covered the fire oil surface, Dimensional direction of the speed of change process, grasps water film-forming foam fire extinguishing agent spreading in the combustion of oil-related parameters change, a deep understanding of the foam fire extinguishing process, and enriched foam spreading theory.
