This study employs computational fluid dynamics methods to analyze bag filters with three structural configurations: non-guided, flat flow-guided, and curved flow-guided systems. The investigation specifically focuses on the influence of these configurations on key parameters, including internal flow field distribution patterns and filter bag load distribution. The evaluation is conducted using indicators such as flow amplitude and the speed variation coefficient. The results indicate that the flow amplitudes for the three structures are 0.41, 0.13, and 0.10, respectively, with notable differences observed in both the flow distribution coefficient and speed variation coefficient. Analysis of flow field uniformity of and particles motion demonstrates that the curved flow guide effectively improves flow field uniformity, providing improved speed distribution and flow allocation at all section heights.
