PROCESSING OF SOLID HOUSEHOLD AND INDUSTRIAL WASTES Russian patent published in 2015 - IPC B09B3/00 

FIELD: process engineering.

SUBSTANCE: invention relates to thermal processes of decontamination of wastes. For processing of said wastes theses are fused in slag melt blown with gas jets. Melting is performed by gas lift technology in circulating slag melt in specially shielded chamber of gas lift furnace with two areas. Wastes are subjected to oxidation treatment in said first area by circulated slag with intensive air mixing unless a foamed fluid state is reached. Slag remained in oxidation area settling chamber is fed to treatment area in gas lift mode by reduction gases. Exhaust gas flow of reduction area is combined with exhaust oxidation gas flow of reduction area. Process temperature control is performed with the help of heat created by electric current of polarised electrodes fitted in settling chambers of oxidation and reduction areas.

EFFECT: higher efficiency of liquid and gas phase interaction.
