STUDY ON ENERGY EFFICIENCY OF BOX TYPE NON-RESONANT SONO-REACTOR
Recently, the energy efficiency of sono-reactors has become one of research focuses in sono-reactors. In this work, a box type reactor with size of 125.5× 44x50 mm3 is designed to research its total energy efficiency and electroacoustic efficiency at non-resonant frequency of 21 kHz; two end surfaces of the reactor, bonded with piezoelectric plates, are used as sound radiation surfaces which are 40x40 mm2 and 15×15 mm2, respectively. The calorimetric method is used to measure the acoustic power from the radiation surface into the box with water, and the sodium hyposulphite solution titration method is used to measure the total energy efficiency. An inductor is connected to the sono-reactor in series for increasing the input power of the sonoreactor. Experimental results show that cavitation effect in the sonicated water is the strongest when the driving circuit is in resonance; the total energy efficiency decreases with the increase of input electric power of the sono-reactor; the size of sound radiation surface affects the total energy efficiency, and the efficiency is high when the radiation surface is small.
