Abstract

Procédé et système de filtration et de stérilisation d'air aspiré, le procédé comprenant principalement les étapes suivantes : en premier lieu, après avoir activé la source d'énergie d'un ventilateur et fait aspirer de l'air par le ventilateur, l'air est alors filtré par un filtre ordinaire, les poussières et les particules arrêtées par le filtre sont stérilisées par un tube à lumière ultraviolette. L'air entre ensuite dans un générateur de plasma, où une énergie électrique à haute fréquence et à haute tension ionise l'air en un plasma d'ozone (ou un plasma à ions négatifs), suite à quoi tous les virus et les bactéries contenus dans l'air sont tués ; l'air mélangé au plasma d'ozone entre alors dans une cuve remplie d'eau ou d'autres solvants utilisés pour adsorber et filtrer toutes les particules fines, une source de lumière ultraviolette étant installée dans la cuve et utilisée pour tuer les bactéries adsorbées dans l'eau ou les autres solvants. L'air filtré est alors extrait par le ventilateur et entre dans un système de séchage filtrant l'air et éliminant l'huile de façon à éliminer l'humidité présente dans l'air. Par conséquent, de l'air exempt de poussières / de particules, de bactéries et de molécules d'eau est obtenu et renvoyé vers l'espace intérieur d'un local.
