Abstract

本发明提供了一种基于液态烃强化破乳及萃取脱除水中有机物的装置及方法，方法包括以下步骤：S1含油废水增压及液态烃萃取剂输入混合萃取器；S2含油废水与分散的萃取剂液滴在混合流道混合；S3旋流分离器对混合液初级分离；S4聚结除油器对水相中残余的微细萃取剂聚结；S5水相减压后输入闪蒸罐，并分别从闪蒸气出口、净化水出口排出；S6旋流分离器和聚结除油器排出的萃取相输送至回收塔；S7气态纯净萃取剂冷凝液化后回收、循环使用。本发明集成混合萃取、旋流分离、聚结分离和闪蒸等多级强化单元，流程紧凑，处理速度快，利用液态烃萃取剂，通过物理剪切聚并与溶剂萃取双重机制，同步高效破坏稳定乳化油滴并直接萃取溶解性有机物。
