Etude de l'empoussièrement des poudres par un test de fluidisation

Abstract : The aim of this study is to use a fluidized bed as a dustiness test based on entrainment and elutriation phenomena for a reconstructed model system. Once the operating conditions were identified, a simple phenomenological model was established, able to predict the amount of dust initially present in a mixture. In order to do that, a parametric study was conducted with bimodal powder mixtures. Thus, large particles simulate the powder and the fine dust. The experimental study was carried out with Geldart A and C particles, in a fluidized bed. Furthermore, the influence of some intrinsic and extrinsic parameters of the bulk on the dust emission was studied. Subsequently, different models present in the literature were tested in order to predict the dustiness. This comparison allowed choosing the model of Santana et al. (1999) which showed a better match with the results of this study.
