Title
(EN) DUAL DRYING PATH WITH EXHAUST RECIRCULATION FOR SOLID WASTE PROCESSING
(FR) VOIE DE SÉCHAGE DOUBLE POURVUE D'UNE RECIRCULATION DES EFFLUENTS GAZEUX POUR LE TRAITEMENT DE DÉCHETS SOLIDES
Abstract
(EN) A technique, method and system for drying a solid waste stream in a pyrolysis recycling installation, including drying the waste stream in a first dryer, feeding the partially dried waste stream from the first dryer to a second dryer, further drying the waste stream in the second dryer to produce a dried waste stream, and feeding the dried waste stream from the second dryer to a pyrolysis unit, wherein the first and second dryers dry the waste stream primarily, or exclusively, using heat generated from the pyrolysis unit.
(FR) L'invention concerne une technique, un procédé et un système de séchage d'un flux de déchets solides dans une installation de recyclage par pyrolyse, comprenant le séchage du flux de déchets dans un premier séchoir, l'acheminement du flux de déchets partiellement séché depuis le premier séchoir vers un deuxième séchoir, le séchage supplémentaire du flux de déchets dans le deuxième séchoir pour produire un flux de déchets séché et l'acheminement du flux de déchets séché depuis le deuxième séchoir vers une unité de pyrolyse, le premier et le deuxième séchoir séchant le flux de déchets principalement, ou exclusivement, à l'aide de la chaleur générée à partir de l'unité de pyrolyse.
