Experimental study on the enhanced separation performance of a vertical corrugated plate dryer under acoustic agglomeration
Year: 2025
Type: article
Abstract: The corrugated plate dryer (CPD) is an important steam-water separation device in pressurized water reactor nuclear power plants. Acoustic aggregation is a non-contact aggregation technology. In this study, the separation performance of a bench-scale vertical CPD under the action of acoustic agglomeration was experimentally investigated. Specifically, the influence of sound frequency, sound pressure level, and inlet flow velocity were explored. The results showed that under the action of the sound field, a CPD separation efficiency of up to 98.9% was achieved. Moreover, the separation performance was highest at frequencies of 700 Hz, The second highest frequency is 1100Hz. The higher the sound pressure level, the higher the separation efficiency of CPD. In addition, the sound field not only significantly improved the separation efficiency at low flow rates, but also increased the critical airflow velocity(CAV). This study provides guidance for achieving acoustic droplet aggregation and water recovery in nuclear power plants.
