Abstract

Titre de l’invention : Dispositif pour la destruction des déchets industriels spéciaux ou toxiques par pyrolyse et sa mise en œuvre. La présente invention concerne un dispositif destiné à détruire des déchets solides préalablement broyés dits MAT par une technique de pyrolyse spatiale ablative, à l’intérieur d’un réacteur de dépolymérisation (200) constitué d’un contenant cylindrique (230) dont la surface périphérique intérieure est recouverte d’une mousse rigide isolante (240) associée à du graphite hautement purifié et recouvert de carbone pyrolytique brillant miroir pour refléter le rayonnement, dans lequel on a fait le vide et où on a porté la température jusqu’à environ 3000°C. Le réacteur de dépolymérisation (200) dispose en son intérieur d’une cage interne (265) constituée de barres de graphites (270) placées successivement verticalement et à intervalle régulier sur un axe circulaire circonscrit, à l’intérieur de laquelle sont introduits par gravité et sans contact les déchets solides à traiter dits MAT qui lors de leur chute sont érodés par le frottement sur les rayonnements émis par les barres de cage (270). Les résidus gazeux et solides sont transférés par un tube dit évacuateur (300) dans lequel est injectée de l’eau au moyen d’au moins une buse (340), vers un récupérateur (400) muni d’un dispositif de refroidissement (440) pour condenser les gaz résiduels et les résidus solides sont stockés par décantation au fond du récupérateur. Les résidus liquides sont extraits du récupérateur au moyen d’une pompe (500). Figure pour l’abrégé: Fig. 2Title of the invention: Device for the destruction of special or toxic industrial waste by pyrolysis and its implementation. The present invention relates to a device intended to destroy previously crushed solid waste called MAT by an ablative spatial pyrolysis technique, inside a depolymerization reactor (200) consisting of a cylindrical container (230) whose peripheral surface interior is covered with a rigid insulating foam (240) associated with highly purified graphite and covered with shiny mirror pyrolytic carbon to reflect the radiation, in which a vacuum has been created and where the temperature has been raised to approximately 3000° vs. The depolymerization reactor (200) has in its interior an internal cage (265) made up of graphite bars (270) placed successively vertically and at regular intervals on a circumscribed circular axis, inside which are introduced by gravity and without contact, the solid waste to be treated, called MAT, which during their fall is eroded by friction on the radiation emitted by the cage bars (270). The gaseous and solid residues are transferred by a so-called evacuator tube (300) into which water is injected by means of at least one nozzle (340), towards a recuperator (400) provided with a cooling device (440 ) to condense the residual gases and the solid residues are stored by decantation at the bottom of the recuperator. The liquid residues are extracted from the recuperator by means of a pump (500). Figure for the abstract: Fig. 2
