摘　　要：为了研究气压和水压对超声雾化喷雾粒径参数的影响;设计了实验平台,选用了阴离子型表面活性剂快渗T配置成浓度为0.07%的溶液进行实验;分析在不同气压和水压的组合之下超声雾化喷雾粒径参数的变化情况。实验结果表明:粒径参数D10、D50、D90、VAD、SMD、NAD随着气压的增加而减小,减小幅度受到水压影响;同时,以上粒径参数也随着水压的增加而增大,增大幅度也会受到气压影响,气压对雾滴粒径变化的影响程度大于水压;当压力改变时,粒径参数D10和NAD的变化趋势呈现高度一致,D50、VAD、SMD粒径增加量呈现高度一致,总体上D90变化幅度最大,D10变化幅度最小。In order to study the influence of air pressure and water pressure on the particle size parameters of ultrasonic atomization spray,an experimental platform was designed in this paper.Anionic surfactant rapid infiltration T was selected to configure a solution with a concentration of 0.07%for experiment.The changes of particle size parameters of ultrasonic atomization spray under different combinations of air pressure and water pressure were analyzed.The experimental results show that the particle size parameters D10,D50,D90,VAD,SMD and NAD decrease with the increase of air pressure,and the decrease is affected by water pressure.At the same time,the above particle size parameters also increase with the increase of water pressure,and the increase will also be affected by air pressure.The influence of air pressure on the change of droplet size is greater than that of water pressure.When the pressure changes,the change trend of particle size parameters D10 and NAD is highly consistent,and the increase of particle size of D50,VAD and SMD is highly consistent.
