Title:
METHOD OF REPROCESSING USED TYRE CASINGS AND A FACILITY FOR CARRYING OUT THE SAID PROCESS
Document Type and Number:
WIPO Patent Application WO/1995/014562
Kind Code:
A1
Abstract:
The invention relates to means of reprocessing solid industrial waste containing rubber, and particularly for reprocessing used car tyres. In order to reduce the environmental impact of the waste reprocessing and to enhance its efficiency, used car tyre casings are loaded into a reactor (1) through a loading device (2). The reactor (1) is heated to a desired temperature of between 400 and 700 �C, the jets (11) being ignited and a circulation flow around the work piece being started with the aid of a pump (12). Once the temperature in the reactor (1) has reached 400 �C, the high-molecular weight compounds undergo conversion by the removal of the volatile hydrocarbons which, together with the steam, enter the cooler (4). On leaving the cooler, the steam and gas mixture enters the condenser (5), where the steam and heavy hydrocarbon fractions condense. The liquid stands and separates into layers in the condensate separator (6). The gas mixture is led back into the system to a consumer, some of it to the jets (11). Once the liquid has settled into layers, it is removed from the condensate separator (6). The hydrocarbons enter a vessel (13) and are directed to a consumer or sent on for further reprocessing. Water from the condensate separator (6) is fed back into the circuit by a pump (12) to produce superheated steam. Water is heated and boils in the cooler (4) for the gases produced in pyrolysis, and the resulting steam is superheated in the unit (10) to a desired temperature of between 400 and 700 �C. A solid residue is left in the reactor (1) in the form of a porous pyrocarbon and metal cord. The reactor is cooled and depressurised with the aid of the unloading device (3). The solid residue is conveyed by a conveyor (8) to a magnetic separator (7) which separates the metal impurities. The finished pyrocarbon enters the receiving hopper (9).
