La faisabilité de l'électrofiltration d'une atmosphère chargée en poussières de bois : Etude expérimentale et numérique

Abstract : Wood dust causes a number of pathologies including cancers of the upper respiratory tract and allergic-type diseases. Considering the dangerousness of this dust, a filtration system high performance is required for the treatment of work environments. For this purpose, we have investigated the electrofiltration of wood particles-laden atmospheres. A dust-controlled wire-cylinder electrostatic precipitator has been created and developed at the LERMAB laboratory and a computer code has been developed using the software Comsol Multiphysics. The study of the filtration efficiency has been carried out. This efficiency is larger than 99.9% for the range of fine particles [0.3 µ m - 1 µ m]. The experimental study allows us to identify various parameters governing the electrofilter in operation. The numerical model, in perfect agreement with the experimental results and with the literature, allows to describe with a good precision local and global phenomena occurring in wire-cylinder electrostatic precipitator. It is a good tool for the design of electroprecipitators.
