PRODUCTION OF FINELY-DISPERSED IRON-BEARING PRODUCT FROM SEPARATED WATER-OIL-SCALE-BEARING WASTES Russian patent published in 2014 - IPC F23G7/00

Abstract RU 2520617 C1

FIELD: metallurgy.

SUBSTANCE: proposed method comprises heating of wastes by combustion products. In compliance with this invention, water-oil-scale-bearing wastes are separated to separate components with extraction of oil and water by sublimation in cylindrical stationary inclined reactor. The latter is equipped with vaned rotor, vanes being fitted with clearance with respect to reactor walls. Wastes are heated by heat carrier high-rate vortex flow in countercurrent at minimum oxygen content in said heat carrier at 500-900°C by combustion products obtained at combustion air flow rate of α=0.6-0.8.

EFFECT: product suitable for pelletising of fine iron-bearing wastes by direct compaction of sintered scale, lower power consumption, lower costs.
