PYROLISIS PROCESS AND SYSTEM FOR RECLAIMING DESIRABLE MATERIALS ESPECIALLY FROM CUTTED VEHICLE TIRES AND PYROLISIS SYSTEM FOR RECLAIMING CARBONISED AND WASTE IRON FROM CUTTED VEHICLE TYRES

摘要

The present invention relates to a process for the extraction of individual components of a cut product by pyrolysis, a process for the extraction of certain components of a vehicle's tire by pyrolysis, a single component of a pyrolysis system for vehicle tires In the process of recovering individual components of the cut product of the present invention by pyrolysis, the product pieces are transported from a single container to a pyrolysis chamber; heating the product pieces to the first temperature of the first heating zone of the pyrolysis chamber; moving pieces of the product from the first heating zone to a second heating zone of the apirolizing chamber; heating the pieces of the product to a second temperature independent of the first temperature in the second heating zone; moving pieces of the product from the second heating zone to a third heating zone of the pyrolysis chamber; the pieces of the product are heated in the third heating zone to a third temperature independent of the second temperature; finally, the pieces of product are removed from the apirolizing chamber and the individual components are separated. In the process of extracting individual materials from vehicle cut tires by pyrolysis, the tire pieces are introduced into a rotary furnace (52) having a dispensing tip and an outlet end, which is generally air-free and is divided into heating zones; heating individual heating zones of the rotary furnace (52) to different operating temperatures; passing the tire pieces through the heating zones from the feed end (58) of the rotary furnace (52) to the outlet end of the rotary furnace (52) by pyrolizing the tire pieces during passage through the rotary furnace (52); removing the pyrolysed tire pieces from the rotary kiln (52); and separating the pyrolized tire pieces into various components. One pyrolysis system (10) according to the invention comprises a feeding chamber (32) for transferring vehicle tire pieces; a dispensing means for discharging the tire pieces from the metering chamber (32); comprising a dispensing tip (58) and an outlet end having a generally air-free pyrolysis section (14), the dispensing end (58) of which is formed of rubber tires receiving from the dispensing means, the pyrolysis section (14) being divided into several individual heating zones heating as they pass through the apirolizing section (14), further comprising pyrolizing the tire pieces from the feeding end (58) of the pyrolysis section (14) to the end of the outlet; and the pyrolysis section (
