为了研究消防领域细水雾灭火系统的关键部件———细水雾喷嘴的雾化结构形式 ,以空气和水为介质 ,利用马尔文激光粒度分析仪对两相流乳化型细水雾喷嘴的雾化特性进行了详细的研究 .分析了该型喷嘴的工作特点 ,研究了不同供水压力、供气压力及气液比对喷嘴雾化特性的影响 ,为细水雾灭火系统及其喷嘴的设计方法和检验标准提供了依据 .试验结果表明 :该结构喷嘴的雾化性能完全满足细水雾灭火系统的性能要求
In order to study the atomizing structure of the water mist nozzle, which is the key part of the water mist fire extinguishing system in the field of fire protection, the Malvern laser particle size analyzer Atomization characteristics were studied in detail.The working characteristics of this type of nozzle were analyzed and the effects of different water supply pressure, supply pressure and gas-liquid ratio on the atomization characteristics of nozzle were studied, and the design of water mist extinguishing system and its nozzle Methods and test standards provide the basis for the test results show that: the atomization performance of the structure of the nozzle fully meet the water mist fire extinguishing system performance requirements
