Method and apparatus for incinerating waste

摘要

The invention provides a method and apparatus for incinerating waste, wherein the waste is one or more of an organic waste and an inorganic waste. The apparatus includes a grinder for grinding a mixture of the waste and calcium carbonate. The ground mixture is then fed to a molten metal bath contained within a crucible. Thereafter, a heating member configured proximal to the crucible combusts the mixture of the waste and the calcium carbonate to form one or more of slag and one or more acidic gases. On combustion, the one or more acidic gases are neutralized by calcium hydroxide produced as a result of combusting the calcium carbonate. Additional metal compounds usable as fertilizers are also produced in response to reacting with the one or more acidic gases.

主权项

1. A compact conic apparatus for incinerating waste to make fertilizer, the apparatus comprising:
a spinning centrifugal waste grinder for grinding a waste mixture of the waste with calcium carbonate and for centrifugally distributing the ground waste mixture; a crucible coaxial with the spinning centrifugal waster grinder and removably attached below the spinning centrifugal waster grinder; a crucible cover concentric with the crucible; a combustion chamber between the crucible and the crucible cover for oxidizing the waste mixture from the waste grinder, the combustion chamber including a molten metal bath; a heating member attached to the bottom of the crucible cover and configured proximal to the molten metal bath for combusting the mixture of the waste and the calcium carbonate to produce at least one of at least one acidic gas and a slag, the slag comprising calcium oxide, wherein the calcium oxide reacts with moisture present in the waste to produce calcium hydroxide, wherein at least one of the molten metal and the calcium hydroxide neutralizes the at least one acidic gas to prevent corrosion of the apparatus and generates metal compounds usable as fertilizers, wherein the heating member facilitates combustion at a temperature ranging between a melting point of a metal in the molten metal bath and a boiling point of the metal in the molten metal bath; at least one heat exchanger coaxial with the spinning centrifugal waste grinder and coaxial with the crucible; and an insulator concentric with the at least one heat exchanger.
