Experimental research on enhancing heat and mass transfer of porous ceramic membrane with acoustic field

Abstract

Transport membrane condenser is a water heat recovery technology based on condensation mechanism. Limited by the price of ceramic membrane, it focuses on enhancing the heat and mass transfer technology of ceramic membrane. Acoustic enhancement of heat and mass transfer is an efficient enhancement method. In order to explore the heat and mass transfer characteristics of ceramic membrane enhanced by audible sound field under different condensation mechanisms, the corresponding experimental platform was built. The results show that due to the condensation characteristics of capillary condensation, the heat and mass transfer performance of the nano membrane under the action of sound field is greatly improved, with a maximum increase of 53.44% and 53.22%, respectively; This article presents an analysis of the economic advantages of utilizing acoustic waves in conjunction with ceramic membranes. It is found that the recovery period can be shortened by 3.2 years when acoustic waves are employed. The findings of this study offer a valuable foundation for improving heat and mass transfer in flue gas moisture recovery systems utilizing ceramic membranes.
