Abstract

La présente invention concerne un dispositif épurateur à échange d'ions pour l'élimination sélective d'un gaz chimique à l'état de trace. Le dispositif a une structure simple et compacte dans laquelle un filtre chimique cylindrique ou en forme de rouleau ayant une capacité d'échange d'ions est couplé aux parties internes d'aubes d'une turbine constituant une soufflante centrifuge. Le dispositif peut purifier une atmosphère par élimination sélective d'un gaz chimique à l'état de trace, qui est un polluant en phase gazeuse dans l'air. Dans le dispositif, un liquide de régénération est contenu au niveau d'un côté inférieur dans un boîtier de la soufflante centrifuge de telle sorte qu'une partie du filtre chimique est immergée dans celui-ci et le filtre chimique couplé à la turbine est régénéré en étant amené en contact périodique avec le liquide de régénération avec sa rotation conjointement avec la roue et a ainsi une durée de vie prolongée.
