Abstract

Abstract

Practical engineering applications and previous studies have confirmed that perforated electrostatic precipitator （ESP） plates are effective at suppressing dust re-entrainment. However， the current design of their structural parameters still mainly relies on empirical experience. Moreover， the effects of perforated plate structures on the electric field properties of electrostatic precipitators， the suppression of dust re-entrainment， and the improvement of dust collection efficiency are still limited to qualitative analysis and lack robust quantitative theoretical support. Using numerical methods， this study investigated the effects of perforated plate porosity and baffle configurations—including the relative position between the baffle and the perforated plate， baffle inclination angle， baffle spacing， and the clearance between the baffle and the plate—on the electric field， flow field， and dust removal efficiency of the perforated-plate electrostatic precipitator. The results showed that the presence of baffles had a positive effect on the perforated-plate electrostatic precipitator. Based on the goals of suppressing dust re-entrainment and improving collection efficiency， the optimal design parameters were determined as follows： a porosity of 43.5%， a baffle orientation facing the center of the plate， a baffle inclination angle of 55°， a baffle-to-plate clearance of 3 mm， and a baffle spacing of 45 mm.
