摘　　要：考察了釜径为386mm的搅拌釜内搅拌桨的类型、挡板和气体分布器等对自浮颗粒三相体系搅拌混合临界搅拌转速的影响 ,得到了回归的关联式:Ncr=CVSawbdcdSe,相对误差为3.34 %～11.58 %。该式可用于指导工业过程的设计和放大。The influences of impeller types, baffle configurations and gas sparger on critical speed of floating particle in an agitated vessel were investigated.The correlations of critical speed were obtained: Ncr=CVSawbdcdSe which could be used in the scale-up of this kind of process.

关 键 词：自浮颗粒 三相体系 临界转速 搅拌桨 混合
