Hazardous waste removal method and apparatus
First Claim
1. In a glass making furnace having a melting chamber for melting and heating materials contained therein, a refining chamber connected to said melting chamber via a ventilated throat in a bridge wall and having a glass exit port, a first doghouse for entering materials into said melting chamber, a burner unit for melting said raw materials into a molten mass and for heating said molten mass, a first and second primary checkers chamber connected to said combustion chamber via a respective air port, a divider structure separating said primary checkers chambers and respective air ports corresponding thereto, at least one secondary checkers chamber coupled to said primary checkers chambers and to at least one stack including a flue for causing circulation of air flow in alternate directions through the combustion chamber,the improvement comprising:
- at least one hazardous gas injection port coupling to each said primary checkers chamber for injecting gaseous hazardous waste thereto;
at least one hazardous liquid injection port coupling to said melting chamber for injecting liquid hazardous wastes directly into said melting chamber.

Abstract
A method and apparatus for the high temperature destruction by pyrolysis and incineration of organic and inorganic gaseous, liquid, and solid toxic and hazardous compounds. The apparatus has a melting chamber and a combustion chamber wherein solid, sludge liquid and gaseous compounds are separately or simultaneously eliminated. In the melting chamber of the apparatus, a molten mass media operates at temperatures between 2200 and 2900 degrees F. Directly above the molten mass a flame impinges upon the molten surface at a temperature of 3000 degrees F. and above. Solid, liquid, and gaseous hazardous wastes are introduced into the melting chamber either on or beneath the surface of the molten mass wherein the waste is destroyed. Due to the operating sequence of the apparatus, the liquid and solid waste compounds may be in the molten mass in excess of eight hours. In addition, hazardous liquids may be mixed with liquid fuels and introduced into the upper combustion chamber as the combustion media at temperatures of 3000 degrees F. Hazardous gases and particulate may also be introduced into the upper combustion chamber and mixed with the gases in the combustion media and are in the chamber in excess of four seconds. The final product is cooled and may be reused in part in a subsequent charging batch.

5. In a regenerator type glass furnace having a melting chamber, a refining chamber, a doghouse, a plurality of checkers chambers and a stack, a process for neutralizing hazardous or toxic waste material comprising the steps of:
-
generating a flame in a combustion chamber immediately above said melting chamber, said flame directly impinging on a surface of molten mass contained in said melting chamber and said molten mass being largely comprised of raw materials for making glass; injecting into said molten mass in said melting chamber solid or sludge type hazardous or toxic waste material through said doghouse; continuing heating said molten mass by said flame while circulating said molten mass in said melting chamber; transferring said molten mass from said melting chamber to said refining chamber upon destruction of certain hazardous or toxic waste material embodied therein; and recovering a resultant glass product from said refining chamber. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17)
