摘　　要：研究了不同高度、不同数量和不同布置方式的挡板组合对自浮颗粒三相体系的搅拌混合的影响，发现挡板对自浮颗粒的三相混合有很大的影响，其中不对称的３ 块全深度挡板对自浮颗粒的下拉是最有效的。The influence of twelve kinds of baffles on gas?liquid?floating particle mixing in an agitated vessel is considered in the partⅡ. Three kinds of baffle configurations are studied in this work: the full?length baffle, the partial?length baffle in raised position, and the partial?length baffle in lowered position. The influence of baffle arrangements on mixing of gas?liquid?floating particle is very large. Of all baffles used, three asymmetric full?length baffles are the most efficient for the drawdown of floating particles. The correlations of the relative power and the gas hold?up for many baffles and impellers combination are obtained.
