METHOD OF PLASMOTHERMAL PROCESSING OF SOLID WASTE Russian patent published in 2023 - IPC F23G5/27 F23G5/24 

FIELD: waste disposal.

SUBSTANCE: invention can be used in industry and municipal services when processing waste of various compositions and physical states. A method of plasma-thermal processing of solid waste, in which there is a continuous supply of air into the upper working chamber of a furnace reactor, supply of raw materials for ignition into the upper working chamber onto the outer truncated-cone-shaped surface of the middle working chamber of the furnace reactor, ignition and heating of the middle working chamber. Subsequent feeding of waste into the upper working chamber, drying, heating and burning until flammable pyrolysis gases are formed, which are then directed through the gas outlet openings through recirculation pipes from the upper working chamber through the lower working chamber into the middle working chamber, limited by an internal truncated-cone-shaped space, inside which a plasma cloud is formed, heating the truncated cone-shaped surface from the inside. At the same time, the air continuously supplied through the lower working chamber is pushed into the internal truncated-cone-shaped space of the middle working chamber, under the pressure of which the plasma cloud is transferred through holes in the truncated-cone-shaped surface in the form of plasma jets into the upper working chamber, ensuring thermal destruction of waste throughout the truncated-cone-shaped area at the temperature of the superadiabatic combustion conditions. The resulting pyrolysis gases are additionally enriched with air along the perimeter of the truncated part of the cone, after which a flow of heated air-enriched pyrolysis gases is thrown into the lower working chamber, returning the upward gas flow to the operating cycle carried out in the furnace reactor. Downward flow of contaminated pyrolysis gases under pressure is directed into the afterburning chamber, where they are heated to the temperature at which harmful substances decompose into molecules, and the clean gases are cooled and discharged into the exhaust pipe.

EFFECT: increased efficiency of the separation process.
