METHOD OF PROCESSING SOLID WASTES Russian patent published in 2018 - IPC F23G5/27 C10J3/00 C10B53/00 

FIELD: recycling and disposal of waste.

SUBSTANCE: invention relates to the complex processing of solid waste and can be used for utilization of organic solid household and other solid waste. Complex contains a module for preliminary preparation and supply of solid waste, a turbo-vortex thermal reactor module, a synthesis gas purification module and a power converter module. Module for preliminary preparation and supply of solid waste is made up of a sorting complex, a drying crusher and a storage hopper, dried to a predetermined level of a solid waste mixture, which is arranged to subsequently feed the dried solid waste mixture to the turbo vortex thermal reactor module. Module for preliminary preparation and supply of solid waste is equipped with a device for tearing packages and a magnetic separator and is adapted to select non-flammable fractions. Turbo-vortex thermal reactor module is made up of a turbo-vortex thermal reactor and a combustion chamber proper. Turbo-vortex thermal reactor contains a coaxially located reaction chamber, the walls of which are made of heat-resistant material, an external thermal circuit chamber, the walls of which are also made of heat-resistant material, and an activator device for creating a vortex effect. Reaction chamber has a circular shape in the cut along the diametrical plane, and in the cross section there is an oval shape, the internal volume of the reaction chamber is 0.3–0.5 m³. Activating device is coaxially located inside the reaction chamber. Chamber of the external thermal circuit is made in the form of a hollow jacket surrounding the reaction chamber, which is insulated from the external environment, wherein the outer thermal circuit chamber is installed in such a way that it does not completely cover the side portions of the surface of the reaction chamber. Chamber of the external heat circuit contains the heat supply pipes connected to the combustion chambers and the flue gas outlet. Reaction chamber on the side has feed pipes for the prepared raw material and a discharge port for the products of processing, the external thermal circuit chamber is connected to the drying-crushing machine of the module for preliminary preparation and supply of solid waste. Synthesis gas purification module is equipped with a flue gas cleaning unit, which contains a related afterburner, a cyclone and a scrubber.

EFFECT: technical result is a simplification of the system design, increase of its reliability, increase of efficiency of processing of domestic wastes, as well as ensuring the maximum waste-free process of pyrolysis of domestic waste with simultaneous reuse in the pyrolysis process of the working bodies obtained in previous operations, with the production of synthesis gas at the output.
