摘要

气-液旋流分离器内部流场复杂

结构尺寸等因素对其分离效率影响较大。针对排气管直径、插入深度、偏置角度、偏置距离以及增设底流口防返混锥5个结构因素进行正交试验设计

利用Fluent软件对16组有代表性的水平组合模型进行数值模拟

用极差法找出各因素优化水平组合以及各因素对分离效率和压降的主次影响顺序

最后通过综合平衡法找到最优组合

并分析了优选结构下液滴粒径和入口速度对分离效率的影响。

Abstract

Gas-liquid cyclone separator has complex internal flow field

its separating performance is greatly affected by structural factors.In this paper

five structural factors were considered to carry out the orthogonal test design

including the exhaust pipe diameter

inserting depth

angle offset and offset distance and adding underflow anti back mixing cone.Through 16 groups of representative level combination model

numerical simulation was conducted using Fluent software.Moreover

the extremum difference analysis method was applied to find the factor combination mode and the influence sequence of each factor on separation efficiency and pressure drop.Finally

through the comprehensive balance method

the optimal factor combination mode was obtained and the effects of droplet size and inlet gas velocity on the separation efficiency were analyzed.
