Abstract

L'invention concerne une cuve de réaction pour traiter des déchets plastiques et des pneus par craquelage, comprenant une enveloppe, une couche d'air chaud à l'extérieur de l'enveloppe, une entrée et une sortie d'air chaud raccordées à la couche d'air chaud, un orifice d'entrée situé sur la partie supérieure de l'enveloppe, un déchargeur situé sur la partie inférieure de l'enveloppe, un orifice d'évacuation pour le gaz produit placé sur la paroi latérale de l'enveloppe et qui est raccordé à la chambre intérieure de la cuve de réaction, une unité de décirage raccordée à la sortie des gaz produits, et un orifice d'entrée de pulvérisation de produits alcalins située sur la partie supérieure de l'enveloppe à côté de l'orifice d'entrée d'alimentation. La poudre ou la solution de produits alcalins peuvent être chargées dans la chambre intérieure de la cuve de réaction par l'orifice d'entrée de pulvérisation de produits alcalins lors de l'étape d'alimentation, il en résulte que les gaz acides produits sont éliminés et que la durée de vie de l'équipement peut être prolongée. Les gaz produits lors de la réaction évacués sont traités par l'unité de décirage, les cires contenues étant converties en mazout, ce qui améliore de manière significative la productivité en combustible.
