超声波在线防垢、除垢与强化传热的实验研究

超声波防垢除垢与强化传热的机理是超声波的空化效应与机械效应.根据这一机理并由水力学计算,首次设计出了较完善的超声波防垢除垢及强化传热实验台,并确定防垢除垢与强化传热实验中所要控制的主要物理参数为:超声波频率、功率、反应体系温度.实验表明:适当提高超声波频率、功率和反应体系温度有利于提高清洗效率.

Experimental Research on Antiscale, Scale Removal and Enhancement of Heat Transfer of Ultrasound

The mechanism of deposition cleaning and enhancement of heat transfer with ultrasonic wave are the cavi-tation and mechanical effect. On the basis of above analysis and hydromechanics calculation , a better experimental platform of ultrasound' s antiscale, scale removal and enhancement of heat transfer is designed , the physical parameters which must be controlled in the experiment are the frequency, power and temperature of reactive system . Tests have shown that enhancing frequency, power and increasing temperature of system can improve cleaning effect.
