Effect of the EHD flow on the collection efficiency of fine particles in wire-plate electrostatic precipitators

This paper focuses on the low collection efficiency of fine particles in air pollutant. Based on analyzing the collection rate of fine particles in electrostatic precipitator (ESP), a two-dimensional model of wire-plate discharge was established. The CFD code FLUENT was used to simulate the ionic winds at typical voltages 25, 40, and 45 kV, respectively. In the process of simulating, the ionic wind was replaced by the dynamic wind. According to the state graphs of ionic winds, the abnormal manifestation of the fine particles collection appeared in 40 kV voltage was explained. This work will provide a theoretical support for optimizing electrodes matching.
