随着世界环保意识的增强,哈龙灭火剂由于其会造成大气污染而被逐渐淘汰。细水雾灭火系统作为一种新的灭火替代技术,具有无环境污染、迅速高效灭火、耗水量低、水渍损失小等特点,从而引起了国际消防界的广泛重视。经过多年的发展,如今细水雾灭火系统已经在航空航天、水上船舶、日常建筑等领域得到了广泛的研究与应用。对于细水雾灭火系统而言,系统工作压力与细水雾喷嘴结构对于雾化效果有很大的影响,而喷嘴的雾化效果直 As world awareness of environmental protection has increased, halon fire extinguishing agents have been phased out as they cause air pollution. As a new fire extinguishing alternative technology, water mist extinguishing system has the characteristics of no environmental pollution, rapid and efficient fire extinguishing, low water consumption and small water loss, which has attracted extensive attention from the international fire protection community. After years of development, the water mist extinguishing system has been widely researched and applied in the fields of aerospace, marine vessels and daily construction. For the water mist fire extinguishing system, the working pressure of the system and the structure of the water mist nozzle have a great influence on the atomization effect, while the atomization effect of the nozzle is straight
