Abstract

Due to the carcinogenic nature of diesel particles, these particles will pose a serious threat to human health. In order to meet this challenge, the attention of researchers and government agencies around the world is focused on achieving an economical and safe technology to control these particles. Given that electrostatic precipitators are one of the most important treatment technologies, this paper deals with the mathematical modeling of a cylindrical electrostatic precipitator and the prediction of the collection efficiency of diesel conductive particles in its various conditions. This sediment consists of a grounded cylinder with a circular cross-section and an excited electrode with negative direct current voltage installed in the center of the cylinder. Using the analytical response of Poisson equations and current conservation, ion spatial charge density, electric potential distribution and electrical volume forces in the electrostatic precipitator channel will be calculated. In this paper, COMSOL software is used for three-dimensional modeling of cylindrical electrostatic precipitators and solving turbulent air flow equations considering volume electric force. The particle charge and motion equations have been implemented in COMSOL software using particle routing physics and the results have been analyzed.
