摘要
工业规模液体内的声处理应用越来越多地得到国内外声学工作者的关注。一般认为,液体内声处理的机理是声空化,因此要扩大声处理的规模,应把研究的重点放在声空化的优化,而不是一味提高声能输入。而对声空化优化的前提则需要找到简单易行、生产上可用的空化测量方法。回顾了声空化检测、测量方法,分析比较后认为:实时谱分析方法更适用于大规模液体声处理的空化测量,需加大力度深入研究。
Industrial scale acoustic processing of liquid is getting more and more attractive in the area of acoustic chemistry.Generally,the mechanism of acoustic processing of liquid is due to cavitation,therefore,to expand the scale of acoustic processing,the study should be focused on optimizing cavitation,rather than increasing only the input acoustic energy.The premise to the optimization of cavitation is to find a cavitation measurement method,which should be simple and useful in industrial production.By reviewing the detection and measurement methods of acoustic cavitation,this paper points out that the real-time spectrum method is more suitable for cavitation bubble measurement in large-scale acoustic processing of liquid,and needs to be studied further.
