Title
(EN) METHOD OF PRECIPITATING AIRBORNE PARTICLES
(FR) PROCEDE SERVANT A PRECIPITER DES PARTICULES EN SUSPENSION DANS L'AIR
Abstract
(EN)
A method of precipitating airborne particles from air comprising contacting the airborne particles with liquid droplets from a domestic aerosol spray device, a unipolar charge being imparted to the liquid droplets during the spraying of the liquid droplets by the aerosol spray device, the unipolar charge providing the droplets with a charge to mass ratio of at least +/- 1 x 10-4 C/Kg, and the unipolar charge being transferred between the liquid droplets and the airborne particles by contact which causes the airborne particles to precipitate due to mutual repulsion.
(FR)
Procédé servant à précipiter des particules en suspension dans l'air et consistant à mettre en contact ces particules avec des gouttelettes de liquide provenant d'un pulvérisateur aérosol domestique, une charge unipolaire étant communiquée à ces gouttelettes de liquide pendant leur pulvérisation par le pulvérisateur aérosol, ce qui confère aux gouttelettes un rapport entre la charge et la masse d'au moins +/- 1 X 10-4 C/Kg, cette charge unipolaire étant transférée entre les gouttelettes de liquide et les particules en suspension dans l'air par un contact provoquant la précipitation desdites particules sous l'effet de leur répulsion réciproque.
