摘　　要：设计加工了一种气水两相流雾化喷嘴和一套完整的实验系统,进行了不同特征结构参数下的雾化效果实验。研究表明,气孔的数量与孔径、水孔的孔径、气孔偏移角、出雾口形式均对两相流喷嘴的雾化性能有很大的影响,其中,气孔偏移角在低压能源下对喷嘴雾化颗粒尺寸分布有重要影响。为低能耗,小粒径的喷嘴结构的优化和除尘装置的设计提供了理论依据和关键技术支撑。A two-phase flow nozzle is designed and manufactured. The whole experimental system is well setted up. The influence of the structural parameters of two-phase flow nozzles and the variation of work parameters on the atomization performance are obtained through the experimental study ,and the quantitative parameters of the influence are obtained. Research shows that. the air cavity, the number of air cavity, liquid cavity, air cavity deviation angle,the pressure of the throttle lever, out of the fog for two-phase flow nozzle have important influence to atomizing performance for low energy consumption. The results provide theoretical basis and key technical support for the nozzle structure optimization and the better application of mining dust removal device.
