REACTOR FOR THERMAL DECONTAMINATION OF WASTES Russian patent published in 2000 - IPC

FIELD: decontamination of pharmacology, medicine, chemical industry, and domestic wastes. SUBSTANCE: reactor designed for decontaminating wastes of all group compositions and size including large lumps has combustion chamber with deflector wall which is curvilinear in vertical section and incorporates gas supply channels; it has zone-by-zone blast grid tilted towards discharge zone, means for feeding gaseous and/or liquid fuel or wastes arranged below grid, device charging channel provided above upper level of tilted grid, and afterburner. Grid is tilted through different angles in zones. Nozzles passing secondary gas to afterburner are facing each other; they are spaced apart through 0.5-1.0 of afterburner width and arranged in tiers at distance from upper edge of deflector wall making up 0.5-2.5 of afterburner width; mentioned nozzles provide for high-speed revolving flow. Axes of gas-supply channels in deflector wall are unidirectional with fluid bed rotation. EFFECT: improved efficiency due to longer residence time of large lumps in heat-treatment zones. 5 cl, 4 dwg
