A new sonoreactor technology is presented here which should give a decisive impulse to sonochemistry in various areas of chemical processing. These exclusive systems use high power converging acoustic waves in a tube to produce a relatively large volume confined acoustic cavitation zone in flowing liquid reagents under pressure. It is well known that numerous chemical reactions are strongly accelerated when they take place inside such a zone. The new cylindrical sonoreactors do not contaminate the processed liquids with erosion products as most other devices do since the cavitation zone is maintained away from the wall of the tube. The processing conditions can be widely varied with pressure, power, temperature, and flow rate. The processing capacity of the largest models may be up to several tons per hour, depending on the required cavitation energy per unit volume to produce the desired process enhancement, using an electric power input of about 50 kW.
本文介绍了一种新的声化学反应器技术，该技术将为化学加工各个领域的声化学发展提供决定性的推动力。这些独特的系统利用管内的高功率会聚声波，在压力作用下的流动液体试剂中产生一个相对较大体积的受限声空化区域。众所周知，当许多化学反应在这样一个区域内发生时，反应会大大加速。新型圆柱形声化学反应器不会像大多数其他装置那样，使被处理液体受到腐蚀产物的污染，因为空化区域与管壁保持一定距离。加工条件可通过压力、功率、温度和流速进行广泛变化。最大型号的加工能力每小时可达数吨，这取决于为实现所需的加工强化效果，每单位体积所需的空化能量，其电力输入约为50千瓦。
