PYROLYSIS REACTOR FOR RECYCLING WORN AUTOMOBILE TIRES

摘要

The invention relates to petrochemical industry. A pyrolysis reactor of the counter-flow type contains the reaction chamber with the endless screw inside the lined cylindrical combustion chamber of the muffle furnace containing the build-in gas non-flame burners throughout the length of the furnace. 2-4 burners installed in the circle of the combustion chamber of the furnace provides for the homogeneity of the burning. Two zones with different heating intensity existing along the length of the reaction chamber in the direction of the movement of the raw material, namely the pyrolysis and coking zone and the zone of baking the coke, allow for optimizing the yield of the product and improving their quality. The shaft of the endless screw is hollow inside. The air supply inside its cavity for cooling the neck and decreasing the temperature of the bearings increases the longevity of the reactor. The invention provides for the high yield of more valuable products of high quality from the rubber crumb allowing for decreasing the length of the reactor due to more intensive and controlled heat supply to the reactive area using gas non-flame burners. Therefore, metal consumption of the reactor is also reduced.
