超声赋能线材表面节能干燥试验技术研究
Experimental Investigation of Ultrasonically-assisted Energy-saving Surface Drying Techniques for Wire Materials
摘要
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 ul-trasonic energy directly to the wire structures so that the solid-liquid interface underwent high-frequency vi-bration and an ultrasonic atomization effect was produced.An energy-consumption model coupling ultra-sonic atomization and high-speed air jets was developed,and comparative experiments were carried out fo-cusing on key parameters such as ultrasonic power and droplet volume.Results show that ultrasound in-duces 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 expo-sure 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 equiva-lent 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.关键词
