Description

technical field [0001] The invention belongs to the field of ultrasonic waves, and in particular relates to an ultrasonic dispersion control method utilizing cavitation intensity feedback. Background technique [0002] In recent years, sonochemistry has been widely used in fields such as traditional Chinese medicine extraction, ore pulp leaching, liquid treatment, dispersion, and emulsification. Research results at home and abroad show that the frequency, amplitude, action time, and action cycle of the ultrasonic vibration system have a great influence on the effect of sonochemistry, and there is an optimal working state for the cavitation effect of sonochemistry. In addition, there are large uncertainties in the temperature, flow, liquid level, concentration, pressure, composition and other parameters of the industrial site, as well as the poor process stability of ultrasonic vibration materials in China. The traditional sonochemical control process is controlled by the ope...

Problems solved by technology

The main reasons are: 1) There is no direct yield detection method; 2) Even if the yield can be reflected indirectly by detecting the sound field distribution of the reaction device, the existing ultrasonic vibration system does not form a closed-loop control scheme; still centralized In the amplitude control of the ultrasonic vibration system itself; 3) The closed-loop control strategy of the existing ultrasonic vibration system in the amplitude is also relatively extensive, and the control accuracy is low
