Abstract

Est décrit un ensemble de filtration d'aérosol biologique. L'ensemble comprend une chambre de séparation ayant une entrée pour recevoir un aérosol chargé biologiquement dans la chambre de séparation et une sortie via laquelle de l'aérosol nettoyé peut quitter la chambre de séparation, la chambre de séparation délimitant un trajet de flux d'aérosol entre l'entrée et la sortie de celle-ci. L'ensemble comprend en outre au moins une première électrode et au moins une seconde électrode, l'au moins une première et l'au moins une seconde électrode sont disposées selon une relation espacée dans la chambre de séparation. L'au moins une première électrode peut être reliée à un premier pôle d'une alimentation en énergie électrique, et l'au moins une seconde électrode peut être reliée à un second pôle de l'alimentation en énergie électrique. L'au moins une première électrode comprend une zone d'ionisation qui est configurée pour émettre un écoulement de particules chargées dans la chambre de séparation pour charger électrostatiquement un matériel biologique à l'intérieur de l'aérosol chargé biologiquement, pour amener le matériel biologique à se précipiter électrostatiquement sur l'au moins une seconde électrode. L'ensemble comprend en outre des moyens pour réguler une vitesse de flux d'aérosol à travers la chambre de séparation.
