Title (EN) PROCESS FOR RECOVERY AND TREATMENT OF HAZARDOUS AND NON-HAZARDOUS COMPONENTS FROM A WASTE STREAM
(FR) PROCEDE DE RECUPERATION ET DE TRAITEMENT DE COMPOSANTS DANGEREUX ET NON-DANGEREUX A PARTIR D'UN COURANT DE DECHETS
Abstract:
(EN) A process is disclosed for separating recyclable materials from a waste stream comprising moving the waste at a specific retention time through heating chambers (24), separating certain evaporated components in a gaseous state. The gaseous components are then transferred through exhaust means (32) for exhausting vapors out of each of the heating chambers (24). In order to inhibit combustion or oxidation inert gases are fed to the heating chambers (24). The evaporated portions of the waste stream are introduced through solid separators and cooling apparatus for separating out portions of the stream and further processing. The materials which have not been vaporized out of the waste stream are conveyed via transverse auger (51) out of the chamber for disposal.
(FR) Un procédé pour séparer des matières recyclables à partir d'un courant de déchets comprenant la circulation des déchets au travers de chambres de réchauffement (24) avec un temps de rétention spécifique, en séparant certains composants évaporés à un état gazeux. Les composants gazeux passent alors au travers de moyens d'aspiration (32) qui aspirent les vapeurs hors de chacune des chambres de réchauffement (24). Afin d'inhiber la combustion ou l'oxydation, les chambres de réchauffement (24) sont alimentées en gaz inertes. La partie évaporée du courant de déchets est introduite au travers de séparateurs de solides et de dispositifs de refroidissement pour séparer certaines parties du courant et continuer le traitement. Les matières qui n'ont pas été réduites à l'état de vapeur à partir du courant de déchets sont véhiculées hors de la chambre par une conduite transversale (51) pour leur destruction.
