摘　　要：针对目前气动雾化喷嘴结构复杂、雾化液滴不均匀等问题,基于气动雾化机理,设计了液相通道直径为0.5mm、1.0mm、1.5mm的3种型号气动雾化喷嘴,以自来水为试验工质,利用相位多普勒粒子测量仪,通过试验探究了气液比、液相通道直径以及液相压力对于雾化形成的液滴粒径和雾化角造成的影响。试验表明,随着气液比及液相压力的增大,液滴粒径逐渐减小,雾化角逐渐变大,雾化效果趋好。The way of pneumatic nebulization has many problems such as complicated structure of nozzle and droplets atomized uneven, it designs three kinds of atomized atomizing nozzles with liquid channel diameter of 0.5mm, 1.0mm and 1.5mm based on pneumatic atomization. With tap water as the working substance and phase Doppler particle measuring instrument, it analyzes test data and the effects of gas to liquid ratio, liquid channel diameter and liquid pressure on the droplet diameter and atomization angle formed by atomization. The test shows that, with the increase of gas and liquid ratio and the pressure of liquid phase, droplet size decreases gradually, the atomizing angle becomes larger, the atomization effect of the nozzle is better.
