螺带式搅拌器在假塑液中的混合及放大的研究

ABSTRACTS Study of mixing and scaling-up of ribbon agitators inpseudoplastic fluids

本文综合研究了螺带式搅拌器在假塑性液体中的混合特性及动力特性，测定了双螺带、内外螺带及螺带螺旋３种类型搅拌器的功率常数Ｋ＿ｐ和Ｍｅｔｚｎｅｒ常数Ｋ＿ｓ，并得出混匀操作和传质工艺过程的放大准则。

A comprehensive study was conducted for the mixingperformance and dynamic characteristics of ribbon agitatorsin pseudoplastic fluids,the power constant KP and Metznerconstant Ks of three-type agitators, i. e. double ribbon agi-tators, inside-outside ribbon agitators, and ribbon screwagitators, were measured,and the scaling-up criteria of uni-form mixing operation and mass transfer process were de-rived.
