Effects on swirling chamber and breaker disk in pressurized-dissolution type micro-bubble generator

This study was performed to investigate the effect on element such as swirling chamber and breaker disk in pressurized-dissolution type micro-bubble generator. And, to show the effect of element measured bubble size distribution, Sauter mean diameter and volumetric mass transfer coefficient as performance indicators of pressurized-dissolution type micro-bubble generator. And the results of experiments was summarized quantitatively. As a results of several experiments, breaker disk was shown up the best efficiency than other cases in aspect of effect on bubble size, which contribution ratio for D 50 and Sauter mean diameter are 27.84%, 45.16% respectively. Also, in aspect of effect on volumetric mass transfer coefficient, swirling chamber B was shown up the best efficiency than other cases. The contribution ratio for volumetric mass transfer coefficient was 345.59%. Hence, the composition of additional equipment for improving efficiency of pressurized dissolution type micro-bubble generator was recommended using breaker disk and swirling chamber B type.
