Abstract
Harmful constituents are removed from solid hazardous waste material by heating the waste in the presence of a continuous flow of oxygen until the waste material becomes an agitated molten aggregate and generates effluvia. The effluvia is conducted through a high temperature zone to destroy organic and other harmful constituents. The effluvia is further processed to achieve acceptable environmental quality. The effluvia processing includes a dual reburn/heat exchanger compartment. The generated molten aggregate is thoroughly mixed and hardens into a ceramic-like aggregate which is environmentally safe.
Claims13
A process for removing harmful constituents from solid waste material, comprising the steps of:
- (a) feeding continuously a particulate mix of the solid waste material into a reaction chamber having three zones;
- (b) heating the mix in a first zone of the reaction chamber in the presence of a continuous flow of oxygen introduced through a rotating and retractable assembly until the solid waste material becomes an agitated molten aggregate and generates an effluvia containing particulate matter;
- (c) conducting the effluvia into a second zone of the reaction chamber wherein the temperature of the second zone is high enough to destroy substantially all organic material in the effluvia;
- (d) conducting an excess of molten aggregate from the first zone to a third zone of the reaction chamber where the molten aggregate is thoroughly mixed;
- (e) conducting the effluvia from the second zone of the reaction chamber;
- and
- (f) treating the effluvia to remove pollutants and achieve acceptable environmental release quality.
