Abstract: A rotating packed device for intensifying mass transfer by centrifugal force was investigated. The apparatus was proved to be of larger capacity, higher efficiency, smaller volume and smaller weight as compared with ordinary separation devices. The rotor dimension was 300 mm in diameter and 40 mm in height, and packed with packings. Distillation test was made with ethanol-water binary mixture in a single rotor device. The data was obtained at 6.9t/(m2·h) reflux rate based on the inner surface and at 900 rpm. The packing thickness inradial direction equivalent to a theoretical plate was 3.93 cm for the φ6×6×0.1 ring packing, i.e, packings one meter in thickness was equivalent to 25 theoretical plates in terms of separation efficiency.

摘要： 本文介绍一种利用离心力强化传质过程的转子传质装置。这种装置具有传质效率高、生产能力大、体积小、重量轻等特点。一个外径为300mm,高40mm,内装填料的转子,以乙醇—水系进行全回流精馏试验。对于6×6×0.1不锈钢压延环填料,在回流率为6.9t/(h·m~2),转速为900rpm的操作条件下,获得每块理论板当量径向的填料层厚度为3.93cm,即每米填料相当于25块理论板的分离效果。
