摘要: <正>液膜分离技术中最关键的一步是破乳,它决定着液膜分离的效率与效果。黎念之采用绝缘电极交流电破乳’‘’,Bailes”‘、严忠等’‘’从改变电源和电极类型等方面开展研究,使电破乳技术成为目前液膜分离过程最有效的破乳方法。但实践证明,含水量较高的W们型乳状液液膜体系,常因加不上电压而使破乳难以进行。而且电破乳时,常常在油水界面形成含水量很高的絮状物(通称sPonge),其中含有大量被提取物,直接影响了液膜的分离效率。为此,作者开发了研磨破乳技术

Abstract: In this paper the mechanism is studied on a novel technique of grinding - demul -sification developed by the authors. The main factors influencing grinding - demulsification are converted to a relation of demulsification efficiency and the collision in unit volume. An empirical formula for calculating demulsification efficiency is established from the experi -mental results.
