Abstract
(EN)
This invention aims at basically solving the problems with a waste plastic decomposing reaction energy supplying method with a reaction structure taken into consideration, and rendering it possible to decompose waste plastics efficiently at a comparatively low temperature and obtaining a recovered product, which has a high value of utilization, with a high efficiency. To achieve this object, for example, a regenerative heat medium using silica-alumina granules which is heated in advance outside a reactor (20) is supplied to the interior of the reactor with pulverized waste plastics also supplied thereto, and the heat medium and waste plastics are mixed with each other to form a moving bed (86a-86e, 88a-88e). The decomposition of the waste plastics is carried out by supplying thermal energy for decomposing the waste plastics from the regenerative heat medium to the moving bed while moving this bed in a predetermined direction in the interior of the reactor. The volatile substances generated in this decomposition reaction are passed through the moving bed and guided via a volatile substance discharge port (31) to the exterior thereof so as to be recovered. The nonvolatile substances are taken out with the regenerative heat medium from a medium recovery port (36), and separated and recovered from the heat medium.

La présente invention vise essentiellement à résoudre les problèmes liés à un procédé pour alimenter en énergie une réaction de décomposition de déchets plastiques, en proposant une entité de réaction permettant de décomposer efficacement les déchets plastiques à une température relativement faible et d'obtenir, avec un rendement élevé, un produit recyclé possédant une haute valeur d'utilisation. Un milieu thermique régénératif contenant des granulés de silice-alumine et préalablement chauffé à l'extérieur d'un réacteur (20) est acheminé à l'intérieur du réacteur en même temps que des déchets plastiques pulvérisés, et le milieu thermique et les déchets plastiques sont mélangés pour former un lit mobile (86a-86e, 88a-88e). La décomposition des déchets plastiques s'effectue par apport d'énergie thermique, pour les décomposer, du milieu thermique régénératif au lit mobile, tandis que celui-ci se déplace dans un sens prédéterminé à l'intérieur du réacteur. Les substances volatiles produites lors de cette réaction de décomposition sont acheminées à travers le lit mobile et guidées, par l'intermédiaire d'un orifice d'évacuation (31), vers l'extérieur de manière à être extraites. Les substances non volatiles sont éliminées avec le milieu thermique régénératif par un orifice d'extraction du milieu (36), puis séparées et extraites du milieu thermique.
