摘　　要：建立了一维活化器中吸着剂颗粒的活化效率预测模型。模型全面考察了水雾蒸发、减速、粒径分布以及液－液凝并等的影响。计算结果表明，液滴初始直径和初速度对颗粒活化效率有最大的影响，使用大粒径、窄分布和高初速度的雾化方式可强化增湿活化效果。通过对颗粒活化效率与实测脱硫效率的相关性分析。A model was established to predict the activation efficiency of sorbent particles by scrubbing of water droplets, with integral considerations on the interactions of water droplet evaporation, deceleration, size distribution and droplet droplet coagulation. The calculation results showed the strong effects of initial diameter and jet velocity of water droplets on the particle activation, and preferred to perform atomization with large droplet size, narrow size distribution and high initial velocity. The analysis of correlation was conducted between the activation efficiency and experimental efficiency of SO 2 removal, identifying that the solution reaction of activated particles was the dominant mechanism of SO 2 removal.
