ABSTRACT:
A system for pyrolysis of hydrocarbon constituents of waste material including a treatment unit featuring a retort with a ellipsoidal cross-section forming a first retort half and a second retort half, the material to be treated being selectively deposited in only one half of the retort at a time during any given period of system operation, to avoid abrasion and wear of the half not in use, thus effectively doubling the life of the retort component. Another feature of a treatment unit according to the invention is a heat reclamation arrangement that introduces gases that have first been combusted to supply heat energy to the retort through a conduit directly into the interior of the retort, to improve the efficiency with which pyrolysis takes place. Further, the treatment unit has an exhaust and cleaning arrangement to render gases produced during pyrolysis substantially free of pollutants such that the gases can be vented to the atmosphere. The exhaust and cleaning arrangement is characterized by a plurality of selectively detachable gas injection tubes, which provide fuel for thermal oxidation of the gases. Each injection tube can be removed for cleaning independently of any other injection tube, and removal can be accomplished without disrupting operation of the system. Still another feature of the treatment unit of the invention is the redundancy and high-temperature resistance of the seal between the retort and other components of the unit.
