摘要:

现有线材干燥采用的高速气流吹除工艺方法存在线材表面液膜极薄、气流作用面积小等问题。将超声能量作用于线材结构,使固液接触面高频振动,产生超声雾化效果。建立了超声雾化与高速空气射流的能耗模型,并围绕超声功率和液滴体积等关键参数开展对比试验测试。研究结果表明:超声通过毛细波与声空化诱发液滴快速铺展与雾化,液膜去除效率显著快于空气射流;在液滴体积10  μL、作用时间18 ms下,360 W超声去除率达到84.37%,而450 W高速空气射流对液膜的去除率仅为8.58%;能耗上,在实现同等去除效果的条件下,超声相比空气射流可使系统能耗至少降低约46.67%,表明超声赋能为线材表面快速、节能地除水干燥是可行的。

Abstract:

Conventional wire drying typically relied on high-speed air-jet blowing, which had issues such as extremely thin liquid films on the wire surfaces and a small area affected by the airflow. Applying ultrasonic energy directly to the wire structures so that the solid-liquid interface underwent high-frequency vibration and an ultrasonic atomization effect was produced. An energy-consumption model coupling ultrasonic atomization and high-speed air jets was developed, and comparative experiments were carried out focusing on key parameters such as ultrasonic power and droplet volume. Results show that ultrasound induces rapid droplet spreading and atomization via capillary waves and acoustic cavitation, and the liquid-film removal efficiency is markedly superior to that of air jets. At a droplet volume of 10 μL and an exposure time of 18 ms, 360 W ultrasound achieves a removal rate of 84.37%, whereas a 450 W high-speed air jet removed only 8.58% of the film. In terms of energy consumption, under conditions producing equivalent removal, ultrasound reduces system energy use by at least approximately 46.7% compared with air jets. This paper demonstrates the feasibility of ultrasonic-assisted rapid, energy-efficient dewatering and drying of wire surfaces.
