Optimizing Particulate Matter Filtration: Evaluating the Efficacy of Electrode Spacing in Corona Discharge Dust Removal Systems

Abstract

This comprehensive study delves into the efficiency of an electrode-based dust removal system, with a specific focus on its capability to filter various sizes of particulate matter: PM1, PM2.5, and PM10. Employing an innovative Corona discharging technology, the research critically evaluates how different electrode spacings influence the efficacy of particle removal. Conducted in a controlled environment, the experiments encompassed a range of electrode distances to ascertain their impact on reducing particle sizes commonly found in indoor air. The methodology involved systematic testing of electrode spacings at 2 cm, 3 cm, and 6 cm, across different particulate matter concentrations. The research utilized a combination of natural sedimentation in control scenarios and active filtration in experimental setups to measure the effectiveness of the dust removal system. Key parameters such as particle charge, airflow dynamics, and the strength of the electrical field across the electrodes were meticulously observed and analyzed. The results of this investigation reveal that electrode spacing is a critical factor in optimizing the removal efficiency of particulate matter. Particularly, the 3 cm electrode spacing emerged as the most effective across all particle sizes, indicating its potential as an optimal configuration for air purification systems. This finding underscores the necessity of a balanced approach in the design of such systems, where both the electric field strength and airflow dynamics are harmoniously aligned. This study contributes significantly to the field of environmental health and indoor air quality control. The insights gleaned from the research provide a foundation for developing more efficient air purification systems, tailored to varying environmental conditions and particulate compositions. The findings also pave the way for future research, exploring the impact of other environmental variables on the performance of electrode-based dust removal systems.
