Abstract

La présente invention concerne un appareil d'élimination de fines poussières utilisant un champ électrique à cordes. L'appareil d'élimination de fines poussières est muni d'une unité d'ionisation qui améliore l'anionisation/la cationisation des particules substances étrangères (comprenant les fines poussières, les composés organiques volatils, les métaux lourds, ou similaires) dans l'air entrant par le chauffage de l'air entrant pour favoriser le taux d'ionisation des fines poussières et l'irradiation d'électrons ou le détachement d'électrons. Afin de recueillir les fines poussières, un procédé d'application d'une tension en courant direct et d'une tension d'un champ électrique alternatif par impulsion (PAEF) susceptible d'effectuer de manière alternative l'entrée de polarité négative/positive sous 10 à 30 cycles/s sont en outre ajoutées. L'appareil d'élimination de fines poussières comprend : une unité de collecte de poussière pour recueillir de manière efficace les particules substances étrangères qui sont anionisées/cationisées dans l'unité d'ionisation au niveau d'une électrode maillée formant un champ électrique en chaos au niveau d'un champ électrique à cordes ; et un filtre adhésif qui est monté de manière détachable au niveau de l'unité de collecte de poussière et est enduit de glycérine faisant adhérer dessus les particules substances étrangères. Additionnellement, le PAEF sert de fonction de déplacement des fines poussières qui adhèrent au filet maillé en retour vers le filtre adhésif pour nettoyer le filet maillé. Enfin, l'air anionique propre est fourni à l'intérieur en retirant les fines poussières, en effectuant la stérilisation, et en générant des anions.
