低阻文丘里振弦栅除尘系统内流场模拟研究OACSTPCD

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 sys-tem.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 perform-ance.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.
