Method for thermal distribution of elastomer scrap, preferably tyres and the installation for the execution of this method

The method for air-sealed thermal decomposition of elastomer waste, especially tires, consists in that the thermal decomposition is carried out in an indirectly heated reactor with a horizontal axis of rotation with a movable bed at a temperature 320-400°C and at a pressure in the range between atmo...

Beschreibung
Zusammenfassung:	The method for air-sealed thermal decomposition of elastomer waste, especially tires, consists in that the thermal decomposition is carried out in an indirectly heated reactor with a horizontal axis of rotation with a movable bed at a temperature 320-400°C and at a pressure in the range between atmospheric pressure and gauge pressure up to 0.5 bar, whereas during the loading of the reactor with waste raw material there is added the heaviest fraction from the products separation system in the amount of approx. 0,2-0,5% by weight of the waste raw material, and the same amount of water. The plant for the thermal decomposition of elastomer waste, in particular tires, comprises a rotating steel reactor (1) completely enveloped in a thermally insulated shell (2), a product separator (13), and, preferably, a system for the condensation of oil fractions containing 2-4 diagonally set heat exchangers (15), a washer system (16, 17, 18), and tanks for the oil obtained (21, 22). Preferably inside the reactor there is a screw collar (26) (a spiral belt for scraping/moving the load).
