Title
(EN) METHODS AND DEVICES FOR FILTERING NANOPARTICLES BY BONDING WITH MICROPARTICLES
(FR) PROCÉDÉ ET DISPOSITIF DE FILTRATION DE NANOPARTICULES PAR LIAISON AVEC DES MICROPARTICULES
Abstract
(EN)
Disclosed are embodiments for methods and devices for filtering undesired particles from a medium by bonding the undesired particles to attachment particles. In some embodiments, the methods include receiving a plurality of attachment particles into a volume, where the volume contains a plurality of undesired particles and the medium. The method may also include contacting the plurality of attachment particles and the plurality of undesired particles contained in the medium, resulting in formation of bonded particles in the medium. Contacting may result in collisions, causing bonding between some undesired particles and some attachment particles. Some embodiments of the method also include removing at least a portion of the medium and bonded particles from the volume through a filter coupled to the volume with an exhaust, the filter configured to capture the bonded particles while allowing the medium to pass through.

La présente invention concerne des modes de réalisation de procédés et de dispositifs de filtration de particules indésirables à partir d'un milieu par liaison des particules indésirables à des particules de fixation. Dans certains modes de réalisation, les procédés incluent la réception d'une multitude de particules de fixation dans un volume, le volume contenant une multitude de particules indésirables et le milieu. Le procédé peut également inclure la mise en contact de la multitude de particules de fixation et de la multitude de particules indésirables contenues dans le milieu, entraînant la formation de particules liées dans le milieu. La mise en contact peut entraîner des collisions, provoquant des liaisons entre certaines particules indésirables et certaines particules de fixation. Certains modes de réalisation du procédé incluent également l'élimination d'au moins une partie du milieu et des particules liées du volume par le biais d'un filtre couplé au volume avec un échappement, le filtre étant configuré pour capturer les particules liées tout en laissant passer le milieu.
