Study of the different parameter corona discharge in point-plane Electrostatic Separator

Electrostatic separation is an increasingly used technology in the waste recycling industry. The purpose of this paper is to investigate the corona discharge behavior of direct current in a point–plane electrostatic separator according bias voltage. Physically the corona discharge has been studied by solving partial differential equations represented by Poisson's equation. The various corona discharge parameters is obtained and analyzed using the finite element method (FEM) within the COMSOL Multiphysics software for simulation model to determine the applied voltage effect on the important corona discharge parameters which are electric potential, electric field, electric displacement, current density and space charge density. Clearly, with an increase in the applied voltage, the magnitude of these parameters increases.
