Abstract

Electrostatic precipitators, which are frequently used in industry, use corona discharge to remove particles from dust air. This article uses COMSOL simulation software to conduct numerical simulation on wire plate electrostatic precipitators, exploring the multiple physical characteristics of electrostatic precipitators with different numbers of wire electrodes, and delving into the collection mechanism and phenomenon of particles in electrostatic precipitators. The simulation results show that the space charge produced by the discharge of the wire plate electrode has the highest density near the discharge electrode and gets weaker in all directions. As the quantity of wire electrodes grows, the lateral flow velocity of the airflow in the entire channel decreases, and the removal efficiency of each particle size also gradually increases. By studying the removal efficiency of particles with different radii, it is found that particles at the submicron level have the lowest removal efficiency. Based on the simulation, experiments are conducted on the wire plate electrostatic precipitator to study the voltage and current characteristics and dust removal effect of the electrostatic precipitator under different numbers of wire electrodes. The experimental results demonstrate that as the number of wire electrodes increases, the peak current increases and the dust removal effect improves, achieving good consistency with the numerical simulation results.
