A vertical pneumatic transport line was found to be an efficient collector for 2.4 micron magnesium sulphate particles. Glass beads of average diameter 310 microns and 514 microns, lightly coated with a non-volatile oil, were used as collector particles. The experimental results were in satisfactory agreement with a theoretical analysis based on an idealized single collector particle model. Electrostatic charging of the aerosol prior to entry of the collector particles did not materially alter the bead collection efficiency, with or without radial electric field in the transport line.
On a trouve qu'une ligne verticale et pneumatique de transport etait efficace pour capter des particules de 2.4 microns de sulfate de magnesium. On a employe, comme particules de captage, des perles de verre de diametres moyens de 310 et 514 microns et enduites d'une huile non-volatile. Les resultats experimentaux ont concorde d'une maniere satisfaisante avec ceux d'une analyse theorique basee sur un modele idealise d'un simple particule de captage. La charge electrostatique de l'aerosol, avant l'entree des particules, n'a pas affecte d'une maniere appreciable l'efficacite de captage des perles, en presence ou en l'absence de champ electrique dans la ligne de transport.
