Abstract

La présente invention concerne un épurateur à purification catalytique et concentration destiné à traiter un effluent gazeux organique industriel et incluant un incinérateur à purification catalytique avec séparateur rotatif. Le séparateur rotatif comporte des roues d’absorption rotatives remplies d’éléments fibreux actifs alvéolaires et des roues d’entraînement. Trois quarts des roues d'adsorption rotatives forment une zone d’adsorption, le quart restant formant une zone de désorption. La zone de désorption est reliée par des tuyaux à l’incinérateur à purification catalytique. L’extrémité d’entrée dudit incinérateur est reliée par des tuyaux à l’orifice de sortie de la zone de désorption, tandis que l’extrémité de sortie du même incinérateur est reliée à un ventilateur cyclique de désorption. Ledit ventilateur est relié à l’orifice de sortie de la zone de désorption des roues d’absorption. La présente invention permet d’absorber et de catalyser l'effluent gazeux organique. Elle permet de réaliser d’importantes économies d’énergie. Aucun gaz polluant n’est généré par le procédé de purification, qui offre en outre en rendement élevé.
