Patent ID: 8475726

Claim:
An apparatus for pyrolysing waste, in particular rubber tyres, said apparatus comprising a reactor, wherein the reactor comprises a pyrolysis space, an inlet port and an outlet port enabling a flow across the pyrolysis space of a heating medium for transferring heat required for the pyrolysis, a lower discharge port for discharging solid residues of the pyrolysis, a baffle means made of a plate material and enabling a gravitational slipping of the solid residues towards the discharge port, the baffle means having openings allowing the flow of the heating medium and being arranged to divide the inner space of the reactor to form an upper pyrolysis space above the baffle means and a lower space below the baffle means, wherein one of the inlet and outlet ports is in connection with the pyrolysis space and the other one with the lower space, a conical shaped shut-off member defined by a conical angle, the shut-off member fitting into the discharge port, and an actuated, vertical actuating member, which is connected to the shut-off member, and wherein the baffle means is one of an upside-down truncated cone or an upside-down truncated pyramid shape having a slope between 45 and 80°, means for driving through the reactor a flow of a heating medium for transferring heat necessary for the pyrolysis, and means for discharging the solid residues of the pyrolysis, and a pre-heater arranged above the reactor, said pre-heater comprising a baffle means, a shut-off member, an inlet port and an outlet port for a pre-heater medium wherein the shut-off member of the pre-heater is operated by an actuating tube, and the shut-off member of the reactor is operated by an actuating bar fitted into the actuating tube, wherein the means for discharging the solid residues of the pyrolysis comprises a discharge port of a residue treatment unit.
