Caractérisation et modélisation de l'efficacité de filtration d'un électrofiltre de type Cottrell

Abstract : The electroprecipitator are mainly used in the gas cleaning. The major disadvantage is the oversizing of this apparatus type. This aim of phD work consists in studying and modelling the dispersion of the submicronic particles inside a cylindrical electroprecipitator in order to determine the collection efficiency of this apparatus. After having reviewed the theory on the suspended particles and the technical filtration of gas-particles flow, we propose a synthesis of the means available, for the electrostatic precipitator design. Then we describe the experimental apparatus designed in accordance with the standards in force. We lay particular stress on the experimental evaluation technical of the collection efficiency. Finally in the fourth chapter, we develop a numerical model. It is based on convection-diffusion model with a none uniform electric field and a charge model precise. This prediction tool is based on a finite Volumes method. We finish by a chapter where we expose the results of our experimental study and the simulation results.
