Résumé
In this study, the enhancement of adsorption speed by acoustic wave is investigated to understand how the acoustic wave influences the adsorption performance. The experimental data were obtained to examine the effect of the equilibrium adsorption capacity under the acoustic field. The experimental results showed the adsorption speed with applied acoustic wave became higher than the case without acoustic wave although the equilibrium adsorption amount was the same. The effects of the velocity amplitude, pressure amplitude and frequency on adsorption speed were also examined. The adsorption speed was increased with increasing the velocity amplitude, and then the maximum adsorption speed attained 5.0 times as high as the case without acoustic wave when the velocity amplitude was 1.35 m/s. Based on the experimental data, a correlation expression was proposed, which is agreement to estimate the enhancement effect with the error of ±20% applicable to predict adsorption speed with acoustic wave. The correlation showed good.
