Abstract
An apparatus for removing contaminates from industrial waste streams by thermal destruction in which contaminated waste emission gases are controllably intermixed with hydroxy gas and the mixture thus formed ignited within a combustion chamber of unique design. The temperature within the combustion chamber is maintained at no less than 3000 degrees Fahrenheit to achieve molecular disassociation of the pollutants contained within the emission gas into harmless compounds.
Claims16
An apparatus for thermal destruction of pollutants contained within gaseous emissions from waste material comprising:
- (a) a housing having an internal combustion chamber, said chamber having an inlet and an outlet;
- (b) a source of mixed hydrogen and oxygen gas;
- (c) gas mixing means connected to said source of mixed hydrogen and oxygen and in communication with the gaseous emissions to be burned for mixing said gaseous emissions with said mixed hydrogen and oxygen to produce a gaseous mixture, said mixing means having an outlet;
- (d) a gas injector assembly mounted on said housing, said gas injector assembly having an inlet in communication with said outlet of said gas mixing means and an outlet in communication with said inlet of said internal combustion chamber;
- (e) ignition means connected to said housing for controllably generating an electrical spark within said internal combustion chamber;
- and
- (f) cooling means for controllably cooling said gas injector assembly.
An apparatus for thermal destruction of contaminates contained within combustion emissions from waste material comprising:
- (a) a housing having an internal combustion chamber, said chamber having an inlet and an outlet;
- (b) a source of mixed hydrogen and oxygen gas;
- (c) gas mixing means connected to said source of mixed hydrogen and oxygen and in communication with the combustion emissions for mixing said emissions with said mixed hydrogen and oxygen to produce a gaseous mixture, said mixing means having an outlet;
- (d) a gas injector assembly mounted on said housing, said gas injector assembly comprising:
- (i) an injector element having an inlet in communication with said outlet of said gas mixing means and having a plurality of gas outlets;
- and
- (ii) a burner nozzle having a generally tubular shaped skirt portion adapted to receive said injector element and a flange portion provided with a plurality of gas passageways in communication with said gas outlets of said injector element and also in communication with said combustion chamber;
- (e) ignition means connected to said housing for controllably generating an electrical spark within said internal combustion chamber;
- and
- (f) cooling means for controllably cooling said gas injector assembly, said cooling means comprising an annular shaped ring surrounding said burner nozzle, said ring having a water inlet and a water outlet.
An apparatus for treatment of waste materials comprising:
- (a) a burner means for burning the waste materials to produce combustion emission gases, said burner means having an emission gas outlet;
- (b) a housing having an internal combustion chamber, said chamber having an inlet and an outlet;
- (c) a source of mixed hydrogen and oxygen gas;
- (d) gas mixing means connected to said source of mixed hydrogen and oxygen and in communication with said emission gas outlet of said burner means for mixing said emissions with said mixed hydrogen and oxygen to produce a gaseous mixture, said mixing means having an outlet;
- (e) a gas injector assembly mounted on said housing, said gas injector assembly having an inlet in communication with said outlet of said gas mixing means and an outlet in communication with said inlet of said internal combustion chamber;
- (f) arc producing means connected to said housing for controllably generating an electrical arc within said internal combustion chamber;
- and
- (g) cooling means for controllably cooling said gas injector assembly, said cooling means comprising an annular shaped ring connected to said injector assembly, said ring having a water inlet and a water outlet.
A method for treating waste materials in an apparatus of the character having a combustion chamber, gas mixing means for mixing the waste material with hydrogen and oxygen gas, an injector means for injecting the mixture into the chamber and an electric arc ignition means for igniting a gaseous mixture within the chamber, the method comprising the steps of:
- (a) burning the waste materials to produce gaseous emissions;
- (b) mixing said gaseous emissions with a mixture of hydrogen and oxygen to produce a gaseous mixture;
- and
- (c) introducing said gaseous mixture into the combustion chamber via the injection means and igniting said gaseous mixture with the electrical arc of the ignition means to cause said gaseous mixture to burn at an elevated temperature in excess of 3,000 degrees Fahrenheit.
