Definitions

  • the invention relates to a process for the pyrolytic recycling of plastics, but also parts of special organic waste, old tires, chlorofluorocarbons, etc., and thereby. the recovery of valuable raw materials.
  • the present invention has for its object to provide a method for pyrolysis in modified sand coker, in which the requirements for high usability in operation, low emissions, which are crucial for practical usability, since hardly any exhaust gases, long service life and high throughput rates, rapid heating and so that there is complete degassing in the respective temperature range.
  • the sand koker must be equipped in such a way that it meets all requirements.
  • the invention solves this problem with the method according to claims 1 and 2 and the coking device according to claim 8.

  • HAB hexachlorobenzene
  • PCB polychlorinated biphenyls
  • TCDD dibenzofurans and dioxins
  • Pre-shredded plastics from a separate collection for household waste disposal as well as toxic waste oils, which were bound in sawdust, bound dry paints and lacquer sludge are fed into the pyrolysis reactor 4+ via a lock belt conveyor via a lock 41.

Abstract

Selon un procédé de pyrolyse de matières plastiques, de déchets spéciaux contenant des parties organiques, de vieux pneus, d'huiles usées toxiques, de fluorocarbones chlorés, etc., dans une cokerie modifiée à charbon sablonneux, le matériau est pyrolysé avec ménagement dans un réacteur vertical par un agent caloporteur finement pulvérisé et chauffé jusqu'à 400-700°C environ. L'invention concerne également une installation à deux étages dont le premier étage est chauffé jusqu'à 400°-500°C environ et le deuxième étage jusqu'à 600°-800°C environ.
