NOVELTY - Organic waste utilization includes exposing organic waste stepwise to pyrolysis with reloading of non-decomposed solid residue from a first stage retort at 150-180degreesC, sequentially to retorts for pyrolysis at higher temperature. The gas-vapor mixture from the retorts is directed to dephlegmator(s) for purification, and the tar composition is returned to the retort for re-pyrolysis.    USE - The method is used for utilization of solid organic household and industrial waste. It may be applied in municipal economy, chemical, and petrochemical industries for the regeneration of hydrocarbons into fuel oil and fuel gas.    ADVANTAGE - The method enhances effectiveness of organic waste utilization, obviates overheating and re-heating of finished product, and provides qualitative oil and gas fuel and pyrographite.    DETAILED DESCRIPTION - Organic waste utilization includes multi-stage pyrolysis of waste in a reactor without air access at not greater than 1000degreesC to obtain solid carbon residue and multi-component gas-vapor mixture, cooling gas-vapor mixture in multi-loop circulatory cooling system, extraction of heavy fraction for re-pyrolysis and production of liquid fraction having specified molecular mass and gas on a finite circuit. The organic waste is exposed stepwise to pyrolysis with reloading of non-decomposed solid residue from a first stage retort having a temperature of 150-180degreesC, sequentially to retorts for pyrolysis at higher temperature. The gas-vapor mixture from the retorts is directed to not less than 1 dephlegmator in which the gas-vapor mixture is purified from a tar composition. The tar composition is returned to the retort for re-pyrolysis. The gas-vapor mixture from the dephlegmator is conveyed to a fraction distributor for cooling, and combustion gases from a casing of the last retort are conveyed to casings of the preceding retorts and in combination with combustion gases generated by heaters under casings of all retorts are delivered outside. An INDEPENDENT CLAIM is also included for a dephlegmatic pyrolysis apparatus for organic waste utilization, comprising a pyrolysis reactor with external heating, a feeding device, a system of burners, a gas main line having feeding facilities of the system of burners, a system for outlet of combustion gases from the heating system and pyrolysis gases from the pyrolysis reactor, and a discharging device. The pyrolysis reactor has a device for moving waste from a filling zone to a discharging zone during the time of a process cycle. All parts of the apparatus are made of heatproof and resistant to corrosive environment material. The apparatus comprises not less than two cylindrical retorts (1-3) which are assembled on a frame (4) inside an external housings (5-7) forming a furnace cavity (8-10). The retorts are assembled on 20-40degrees tilt of a cylinder generatrix relative to a horizon. The apparatus includes not less than one dephlegmator (38, 39) which is a cylinder closed from both ends and assembled at an angle of 20-40degrees relative to a horizon. The dephlegmator is internally equipped with pierced metal membranes across the cylinder. Conveyors (11-13) with movable pulleys (14-16) and drive pulleys (17-19) are provided inside each retort. The conveyors are provided with lobes attached to a conveyor band (20) raking up raw material from an inner cylindrical surface of a respective retort casing. Each retort has an opening located in a lowest part provided for discharge of solid residue to the next stage of processing into the following retort, and the dephlegmator is attached to the openings with pipes.
