METHOD AND DEVICE FOR THERMAL NEUTRALISATION OF SOLID WASTES Russian patent published in 2015 - IPC B09B3/00 F23G5/04 

FIELD: machine building.

SUBSTANCE: for solid wastes thermal neutralisation the solid wastes are loaded in drum drier, solid wastes are dried in the drum dryer, the solid wastes are moved from the drum dryer in the drum furnace, they are baked in the drum furnace, gases generated during neutralisation are exhausted, the neutralised solid wastes are unloaded from the drum dryer and drum furnace. The solid wastes are dried and baked by means of heat transfer to them from casings of the drum dryer and drum furnace, respectively. At that the casings are heated in the external heating chambers surrounding the casing of the drum dryer and drum furnace from outside. The suggested device of thermal neutralisation of the solid wastes contains the drum dryer and drum furnace connected by means of the transportation device, each of them has casing and is equipped with the loading chamber, unloading chamber and gas duct to exhaust gases generated during neutralisation. The device is additionally equipped with the external heating chambers surrounding the casing of the drum dryer and drum furnace from outside with possibility of heat exchange.

EFFECT: increased efficiency of neutralisation, reduced quantity of caught sludges or dust in gas cleaning system generated during dust removal of the neutralised gases, reduced power and material consumptions for neutralisation, and overall dimensions and weight of equipment installed in gas cleaning system.
