空化是超声技术应用于各个领域发挥其作用的核心效应,声空化机制是声化学的主动力。在超声正负交变声压下,液体介质中的微泡成长、压缩至溃破的过程中,会形成局部的高温高压、强烈的冲击波和高时速射流,使得介质能产生各种物理、化学和生物效应,如乳化、离散、凝聚等,这样的条件为一些化学反应开启了新通道,从而很好的应用于石油领域。 Cavitation is the core effect of ultrasonic technology applied in all fields to play its role. The mechanism of acoustic cavitation is the driving force of sonochemistry. Ultrasonic positive and negative alternating pressure, the liquid medium microbubbles growth, compression to the collapse of the process, the formation of local high temperature and pressure, strong shock wave and high velocity jet, making the medium can produce a variety of physical and chemical And biological effects, such as emulsification, dispersion, aggregation, etc., such conditions for a number of chemical reactions to open a new channel, which is well used in the oil field.
