在釜径 ３８６ ｍｍ的搅拌釜内，考察了搅拌桨型、挡板和气体分布器等对自浮颗粒三相搅拌混合的临界搅拌转速的影响，并回归了实用的关联式，这对工业过程的设计和放大具有一定的指导意义． In a stirred tank with a diameter of 386 mm, the effects of stirring paddle, baffle and gas distributor on the critical stirring speed of self-floating granular three-phase mixing were investigated and the practical correlations were approached. The design and amplification of a certain degree of guiding significance.
