Pyrolytic apparatus for recycling discarded rubber tires and the like that includes an auto clave shell that is closed at both ends to provide a closed vessel and has an interior refractory lining enclosing a reactor chamber and in conjunction with the vessel forms a gas-oil separation chamber surrounding the lining, heat exchangers within the lining, burners exterior of the vessel for conducting heat to the heat exchangers, a compressor for withdrawing pyrolytic gas given off by the pyrolytic decomposition of tires in the reactor chamber and conducting it to a recovered gas storage tank and a line for conducting oil given off by the decomposition of tires in the reactor chamber to an oil storage tank. The vessel walls are of a sufficiently lower temperature than that in the reactor chamber that the oil condenses on the vessel walls. The vaporized oil and recovered gas passes through cracks between the refractory lining blocks to move from the reactor chamber to the gas-oil separation chamber, a pop-off safety valve on the vessel and opening to the last mentioned chamber being provided to prevent the pressure in the vessel increasing above a preselected level. Non-fluid by products such as carbon black, steel and fiberous materials are recovered from the reaction chamber after the tires are decomposed.
A pyrolytic apparatus for pyrolytically decomposing tires and the like into pyrolytic gas and oil and other by-products, comprising a closed metal vessel having a door for access to the interior thereof, a refractory lining mounted in the vessel to define a gas-oil separation chamber between the vessel and the said lining the reactor chamber and having an inlet and an outlet, means exterior of the vessel and fluidly connected to the heat exchanger inlet for supplying heat to the heat exchanger, means fluidly connected to the heat exchanger outlet for conducting exhaust heat exterior of the vessel and means fluidly connected to the vessel for conducting the pyrolytic gas and oil from the gas-oil separation chamber to a location exterior of the vessel, said refractory lining having a passage means for the pyrolytic gas and oil to flow from the reactor chamber to the separation chamber.
A prolytic apparatus for pyrolytically decomposing rubber vehicle tires and the like into by-products such as pyrolytic gas and oil and carbon black comprising a closed vessel having an interior and an access door opening to the interior, a heat exchanger within the vessel interior, means exterior of the vessel and connected to the heat exchanger for heating the heat exchanger to a sufficiently high temperature to pyrolytically decompose rubber vehicle tires into pyrolytic gas, vaporized pyrolytic oil and by-products, refractory means mounted in the vessel interior for defining a substantially closed reactor chamber having the heat exchanger therein and in conjunction with the vessel defining an oil gas separation chamber at least partially surrounding the reactor chamber and maintaining a sufficient temperature differential between the reactor chamber and the separation chamber that vaporized oil will condense in the separation chamber, said refractory means having means to permit the passage of pyrolytic gas and oil from the reactor chamber to the separation chamber to contact the vessel, said vessel having outlet means opening to the separation chamber for transferring pyrolytic gas and oil from the vessel interior to a location exterior of the vessel.
