摘　　要：随着工业化进程的飞速前进,适用于分离多相不互溶介质的旋流分离器已广泛应用于石化、环保等重点行业。为了提高旋流分离器在全粒径范围内分散相的分离效率,涌现出了多种旋流分离过程强化技术。其中,对入口分散相进行重排序的旋流强化技术因具有加工成本及运行费用低、易于实施、强化效果明显等优势,展现出了重要的应用价值及推广前景。本文聚焦于入口分散相重排序的旋流强化技术,对基于惯性力场和离心力场进行分散相重排序的旋流强化原理、排序器结构类型及应用于液-液、固-液、气-固两相的分散相重排序强化技术及研究成果进行了系统的分析和总结。在此基础上,从组织构建分散相重排序后的多股液流,选择促进多股液流间协同高效分离的旋流场入射方案,强化分散相移动过程中的聚并长大和/或惯性碰撞等角度出发,总结了分散相重排序的技术路线并进行研究展望,从而指导旋流器的旋流分离过程强化及优化设计,助力于旋流分离效率的深度提升。With the rapid progress of industrialization,cyclone separators suitable for separating multiphase immiscible media have been widely used in key industries such as petrochemical and environmental protection.In order to improve the separation efficiency of the dispersed phase in the whole particle size range,a variety of cyclone separation enhancement technologies have emerged.Among them,the efficiency enhancement technology of rearranging the dispersed phase at the inlet of hydrocyclone has shown important application value and promotion prospects,owing to the advantages of low manufacturing and operating cost,easy implementation,and obvious enhancement effect.This paper focuses on the efficiency enhancement technology for the rearrangement of the dispersed phase at the inlet segment.The efficiency enhancement principle of dispersed phase rearrangement based on inertial force and centrifugal force fields,the rearrangement structure types,and the enhancement technologies and research results applied to the dispersed-phase rearrangement in liquid-liquid,solid-liquid,and gas-solid were systematically analyzed.On this basis,the technical route of disperse-phase rearrangement was summarized and the research prospects were also carried out from the following three aspects:the organization and construction of multiple liquid flows after rearranging the dispersed phase,the selection of swirl field injection positions for promoting cooperative and efficient separation of multiple streams,and the enhancement of agglomeration growth and/or inertial collisions during disperse phase movement.The relevant analysis and conclusions aim to guide the separation enhancement and optimization design of hydrocyclones,and to improve the separation efficiency.
