静态混合器在含酚废水萃取中应用研究

Study on State Mixer Application to Extraction of Phenol from Waste Water

使用Ｎ５０３－煤油萃取剂萃取含酚废水。总结了ＳＫ，ＳＶ两种静态混合器及组合方式的应用研究，从萃取效率，传质系数、能耗三方面确定了静态混合条件，在建立的实验装置中，确定ＳＶ混合器为最佳混合器，对实验参数进行了关联，结果发现ＳＫ，ＳＶ的传质系数Ｋ与雷诺数Ｒｅｄ１．５６成正比；ＳＫ，ＳＶ的传质系数Ｋ与能耗ΔＥ０．７成正比，并且提出利用一只静态混合器进行多级萃取的工艺过程。

オt is described that some tests of static mixer SK,SV ad their combination for phenol extraction from wastewater using N503 and kerosene extractant system.While application conditions are defined under comprehensive consideration of extraction efficiency,mass transfer coefficient and energy consumption, SV static mixer is the best one suitable for the static mixer extraction equipment.Corresponding analysis is done with some findings:Mass transfer coefficient K of SK and SV are proportional to Reynolds number Re1.56 and to energy consumption ΔΕ0.7.Anidea of multistage extraction process using a piece of static mixer is presented.These works benefit to industrial application of static mixer scaleup.
