摘　　要：研究建立了超声雾化装置,用激光粒度仪测试了雾化液滴的粒径,并研究了雾化溶液加入量、超声雾化功率、载气流量等雾化参数对超声雾化速率及管路输运损失的影响。结果表明,雾化液滴的粒径约 2.6μm。在一定加液量范围内,加液量的变化对雾化速率影响不大,雾化速率随载气流量和雾化功率的增大而增大;而管路输运损失随载气流量的增大先减小,在载气流量为800cm3/min附近达到最小后,再随载气流量的增大而增大。Ultrasonic atomizing system was set up in this work, and the atomizing properties were studied. The influences of the atomizing sample volume, the atomizing power and the flow rate of carrier gas on the atomizing rate and transporting loss were studied. The size of the droplets measured by laser particle sizer was about 2.6 μm. The atomizing rate changed slightly with the sample volume decreasing, and increased with atomizing power and the flow rate of carrier gas. With the flow rate of carrier gas increased, transporting loss decreased with the flow rate less than 800 cm^3/min, and then increased with the flow rate higher than 800 cm^3/min.
