DEVICE OF LOW TEMPERATURE PYROLYSIS OF WORN TYRES BY CONTINUOUS METHOD WITHOUT PRELIMINARY PREPARATION Russian patent published in 2010 - IPC B29B17/00 F23G5/27 

FIELD: technological processes.

SUBSTANCE: device is intended for recycling of whole car tyres without preliminary preparation. Tyres are loaded into small cylinder - loading device with tightly closing cover and nozzles for smoke gases suction and exhaust. Loading and pyrolysis chambers are separated by tight gate with water cooling facility. Large cylinder serves as trommel in process of pyrolysis. In cylindrical tight pyrolysis chamber there is drive mounted with master gear and water cooling facility. Two guide rims are welded to trommel, one of which has inner threading of tooth to connect to master gear. Helical ribs are also available on inner surface of trommel with windows cut along. Trommel also has conical part with inner ribbing of reverse direction and windows. Protective jacket of device is lined with heat resistant and shielding material with gas burners mounted in it. Air ducts are also provided, as well as outlets of steam and gas mixture and smoke gases with heat exchangers. Steam and gas mixture at the outlet gets into cyclone and via catalyst into cooler-separator. Device is equipped with chambers for collection of solid fraction and metal cord with device for pressing of the latter into briquettes. Device is equipped with auger for product distribution.

EFFECT: invention provides for the possibility of mobile efficient process of tyres recycling that meets eco-friendly requirements.
