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.
