介绍了细水雾灭火技术在国内的主要研究进展.着重阐述了细水雾雾特性测量方法、雾发生方法及灭火有效性实验,并对细水雾的灭火机理和灭火技术未来的发展方向进行了讨论.细水雾的雾特性参数决定了它的灭火性能,目前对其测量的主要方法有LDV/APV、DPIV及扩展的DPIVS技术.传统的雾发生方法有着或多或少的缺点,因而新型的雾发生方法得到广泛地研究,如气泡雾化,所以我们对不同的雾发生方法进行了比较.此外通过一系列的小尺度和全尺度实验研究了细水雾在不同火灾场景下的灭火有效性.
The main research progress of water mist fire extinguishing technology in China is introduced, and the measurement method of mist water mist, the method of generating mist and the effectiveness test of fire extinguishing are mainly described. The future fire extinguishing mechanism of water mist and the future development of fire extinguishing technology are also discussed The fog parameters of water mist determine its fire extinguishing performance, and the main methods to measure it currently are LDV / APV, DPIV and extended DPIVS technology.The traditional mist generation method has more or less disadvantages and thus New methods of fog generation have been widely studied, such as bubble atomization, so we compared the different methods of fog generation.Furthermore, a series of small-scale and full-scale experiments were conducted to study the effects of water mist on firefighting in different fire scenarios Effectiveness.
