摘　　要：为探究除尘系统流场分布情况以及粉尘与液滴颗粒对除尘系统性能的影响,运用Fluent模拟研究气态单相流、气固两相流和气固液三相流的流场分布情况,分析除尘器在不同工况条件下压力与流场分布规律以及颗粒的运动情况。结果表明:除尘系统流场主要受除尘器结构的影响,受粉尘颗粒的影响较小;液滴颗粒的存在会提高系统的除尘效率;加入液滴颗粒后,粉尘运动凌乱度增强,与液滴碰撞作用加强,促进了细微粉尘的凝聚,但同时会影响除尘器流场稳定性,增加除尘系统阻力损失。The distribution of the flow field in the dust collector significantly affects its performance.The uniform distribution of the flow field is conducive to the dust reduction of the system,thus it requires the use of simulation software to simulate and analyze the flow field distribution of the dust removal system.This study used Fluent to simulate the flow field distribution of gaseous single-phase flow,gas-solid two-phase flow and gas-solid-liquid three-phase flow to investigate the effect of droplet particles on the flow field of the dust removal system,and the effect of droplet particles on the dust removal performance.Results show that the dust particles exerts minimal impact on the system flow field;the structure of the dust collector is found to be the major factor affecting the system flow field;the presence of droplets will increase the dust removal efficiency of the system;after the droplet particles are added,the dust movement disorder is enhanced,and the collision effect with the droplets is strengthened,which promotes the condensation of fine dust,improve the dust removal efficiency,but at the same time affects the stability of the system flow field and increases the resistance loss of the system.
