The invention relates to a thermal reactor for the continuous thermolytic recycling of granules obtained from scrap tyres, remains left over from vulcanization and scrap plastics and of similar products. To develop a continuously operating thermal reactor for such a pyrolysis process that allows granules obtained from scrap tyres, remains left over from vulcanization and scrap plastics to undergo continuous thermolytic recycling without additional motor-driven rotating conveying and mixing devices or pneumatic breaking-up devices, it is proposed by the invention ? that the thermal reactor has a run-in part, a heating zone middle part and a run-out part, which are arranged vertically one below the other, ? that in the heating zone middle part there is arranged centrally in the thermal reactor an extraction pipe, the lateral surface of which has numerous holes and/or slits for dissipating the short-chain hydrocarbon compound vapours produced, and conical bells arranged one above the other are pushed onto the extraction pipe and means for extracting the hydrocarbon compound vapours from the extraction pipe are provided, and ? that in the heating zone middle part there are arranged on the outer lateral surface a multiplicity of radially arranged heating plates, which are arranged offset from one another on the heating levels lying one above the other. It has been found within the scope of the invention that, in spite of the poor heat conduction of these materials, it is possible with such a vertical thermal reactor to recycle granules obtained from scrap tyres, remains left over from vulcanization and scrap plastics in continuous operation, since they are subjected to homogeneous mixing and heating. |
