METHOD OF REPROCESSING WORN-OUT TIRES AND/OR INDUSTRIAL RUBBER PRODUCTS AND DEVICE TO THIS END Russian patent published in 2009 - IPC B29B17/00 C08J11/14 F23G5/27 B09B3/00 

FIELD: process engineering.

SUBSTANCE: proposed invention can be used for reprocessing whatever worn-out tires without their preliminary powdering, including tires of BelAZ large trucks, and whatever industrial rubber products. The proposed method of thermal reprocessing of aforesaid products comprises feeding them into chamber for pyrolysis to be carried out by SHF-heating at 2.45 GHz-microwave frequency for 3 to 5 minutes at 400 to 500°C. Pyrolysis is carried out in atmosphere of super-heated steam to be fed into the pyrolysis chamber when its inside temperature reaches 100°C. In pyrolysis, excess pressure of up to 5 kPa is maintained by adjusting the flow rate of formed gaseous products. Note that the standing-wave condition is maintained inside aforesaid chamber, along with uniform distribution of SHF-field. Note also that aforesaid process runs with cyclic feed of tires and rubber products and with cyclic unloading of solid remnant, as well as with continuous discharge of gaseous products.

EFFECT: reduced power consumption, simpler reprocessing, its higher efficiency, which results in on-test gaseous products, high-quality sorbent and alloyed steel scrap.
