摘　　要：利用超声波技术产生的细水雾可作为一种灭火剂,通过冷却、窒息等作用实施灭火。搭建试验平台,分析超声波雾化装置产生细水雾的特性,并设计灭火试验,研究局部应用和全淹没两种形式的灭火有效性和影响因素。结果表明:利用超声波雾化技术产生细水雾并确保足够雾化量和适宜的喷射方向,实施局部应用灭火是可行的;采用全淹没灭火时,灭火效果取决于场所通风情况和空间大小,在相对封闭空间内灭火效果较好。Water mist produced by ultrasonic technology can be used as a fire extinguishing agent to extinguish fire through cooling,suffocation,etc.In this research,the characteristics of water mist produced by ultrasonic atom⁃izing device are analyzed by setting up an experimental platform,and fire extinguishing experiments are designed to verify the effectiveness and influence factors both in local application and total flooding.The results show that it is feasible to put out a fire by locally applying sufficient amount of ultrasonic mist generated by ultrasonic atomization technology in a suitable direction.When total flooding fire extinguishing is adopted,the extinguishing effect depends on the ventilation and space size,and in a relatively closed space,the fire extinguishing effect is obvious.
