空化及其在杀菌中的应用

Cavitation and Its Application on Sterilization

空化是一种非常复杂的现象,空化能够产生极高的瞬时压强与温度,从而能够带来众多的应用,但超声空化用于杀菌却仅仅停留在实验室研究阶段,超声杀菌的处理量是比较少的。描述了超声及水力空化杀菌机理,进行了不同条件下超声和水力空化杀菌实验。结果表明,超声空化与水力空化都有很好的杀菌效果,水力空化的处理量要比超声空化处理量大。

The cavitation is one kind of extremely complex high instantaneous intensity of pressure and the temperature, sterilizating by ultrasonic cavitation has just only been done in phenomenon, the cavitation can cause the extremely thus can bring the multitudinous applications, but the laboratory. The sterilizing capacity of ultrasound is very limited. The mechanism of the sterilization has been studied, Cavitation sterilizing experiments have been done. The result indicates that, the ultrasonic cavitation and the hydrodynamic cavitation all have the very good sterilization effect, the hydrodynamic cavitation can process more than the ultrasonic cavitation.
