功率超声作用于液态媒质时 ,空化作用会在局部点产生 5 0 0 0K以上的高温和 50MPa左右的高压 ,并伴有强烈的冲击波和时速达 40 0km的射流 ,机械作用会产生高频变化的机械运动 ,加速度可达重力加速度的 1 50 0倍 ,这些独特的效应令其在化工领域中的应用越来越广泛。本文主要从超声化学、超声场强化分离、结晶、沉淀、雾化、乳化和破乳等方面综述了功率超声在化工领域中应用现状和发展趋势 When ultrasonic power is applied to the liquid medium, the cavitation will generate a high temperature of over 50,000 K at a local point and a high pressure of about 50 MPa accompanied by a strong shock wave and a jet of 40 0 ​​km / h, and the mechanical action will produce high frequency variations Of the mechanical movement, acceleration up to 1 50 0 times the acceleration of gravity, these unique effects make it more widely used in the chemical industry. In this paper, the current status and development trend of power ultrasonic in the field of chemical industry are summarized from the aspects of ultrasonic chemistry, ultrasonic enhanced separation, crystallization, precipitation, atomization, emulsification and demulsification
