A 3D NUMERICAL INVESTIGATION ON THE CHARGED PARTICLE BEHAVIOR IN WIRE-TO-PLATE DBD ELECTROSTATIC PRECIPITATORS

Abstract

A numerical model was developed to represent the effects of dielectric barrier discharge on a wire-to-plate electrostatic precipitator. For the first time, a time-dependent, multiple-particle trajectory model was implemented, and the precipitation characteristics of particles with micron- and submicron-diameters under field and diffusion charging mechanisms were investigated. 100 Hz and 1kHz frequencies were considered in modeling dielectric barrier discharge currents and the system's space charge characteristics, with significant differences in electrical parameters and precipitation efficiency. Particles with diameters varying from 0.3µm to 5µm, injected into the precipitation channel that has free flow velocities of 0.5m/s or 1m/s. The conducted electrical simulations show peak space-charge densities of 10.7 mC/m3 and 12.9 mC/m3 for 100Hz and 1kHz scenarios, which, in turn, yield electrohydrodynamic force values of 8,193N/m3 and 87,654 N/m3, respectively. Based on these results for the electrical field and electrohydrodynamic properties, submicron (0.3µm diameter) particles display accumulated charge numbers of 400 and 261 at the end of each electrical cycle for the 100Hz and 1kHz meter cases. The particle precipitation results qualitatively confirm the model configuration, whereas the electrical characteristics are validated against the available literature.
