超声波雾化技术是利用超声波特殊的性能来雾化水的新型喷雾技术,该技术能使水充分雾化,实现微细水雾捕尘。利用上述原理产生水雾的装置称为超声波雾化装置。人们早就从事过利用超声波雾化液体，促进燃烧，提高传热和减少污染的研究。但是由于雾化机理的复杂性，充分理解和证实超声波对这些因素的真实影响是非常困难的。因此，我们首先要了解超声波雾化的基本原理。对于弱声，例如我们日常接触的声音，声场中的媒质介点(这里首先指气态质点)只不过在平衡位置振动，但是对于远比这种声音强得多的声场，在其中的媒介质点不仅被振动，而且还产生人们所熟知的超声波二次效应。这时媒质质点被移动，形成一种气流，即所谓的“声风”现象。如果将液面攀露在这样的声场中，使液体经历初期波动，然后是大振幅的波动，接着形成大液滴，最终液滴分离，雾化实现。

Ultrasonic atomization technology is a new spray technology which uses the special performance of ultrasonic to atomized water. This technology can make water atomized sufficiently and realize the fine water mist catching dust. The device for generating water mist by using the above principle is called ultrasonic atomization device. People have long been engaged in the research of using ultrasonic atomization liquid to promote combustion, improve heat transfer and reduce pollution. However, due to the complexity of atomization mechanism, it is very difficult to fully understand and confirm the real influence of ultrasonic on these factors. Therefore, we should first understand the basic principle of ultrasonic atomization. For weak sound, such as the sound we are in daily contact with, the medium point in the sound field (here first refers to the gaseous particle) only vibrates in the balance position, but for the sound field far stronger than this sound field, the medium particle in it is not only vibrated, but also produces the well-known ultrasonic secondary effect. At this time, the medium particles are moved to form a kind of air flow, which is called "sound wind" phenomenon. If the liquid surface is exposed in such a sound field, the liquid will experience initial fluctuation, then large amplitude fluctuation, and then form a large droplet, and finally the droplet separation and atomization will be realized.<br>
