Abstract
Example embodiments of the present invention relate generally to medical waste management and more specifically to a method and apparatus for carbonization of waste material using convective heat from the metallic inner surface of a waste treatment chamber and superheated nitrogen gas.
Claims14
A method for treating waste material, the method comprising:
- heating nitrogen gas at a pre-determined high temperature until it is converted into superheated nitrogen gas;
- allowing said superheated nitrogen gas be in contact with the waste inside the heating chamber while at the same time displacing the air inside the treatment chamber;
- heating of the waste thermal treatment chamber;
- introducing the high temperature nitrogen gas into the waste thermal treatment chamber;
- introducing said nitrogen gas and hydrocarbon gas coming from the treatment chamber into the flame being used for heating said nitrogen gas such that the heating value of the heat being generated by said flame is increased;
- heating waste material by said heat of increased heating value;
- collecting hydrocarbon gas produced during heating of said waste material;
- introducing said hydrocarbon gas into the said flame as fuel, thereby removing highly potential pollutants in the gas waste being treated;
- and
- carbonizing the waste materials through nitrogen gas filled chamber and heating the chamber increasing its inside temperature and pressure.
7 more elements
An apparatus for treating waste material, the apparatus comprising:
- an insulated structure having a plurality of heating assemblies being held thereof, each of said heating assemblies being arranged in a manner wherein it is capable of providing flame heat in said insulated structure, said insulated structure being made such that it is capable of accommodating and disposing waste materials being heated and carbonized therein, insulated structure includes an insulated hollow outer shell member and hollow inner shell member that defines a heating chamber disposed therebetween, a waste heating chamber being defined by said inner shell member, and conveying means provided within the inner shell member being held thereof in a manner wherein it is capable of providing movement and disposal of the heated and/or carbonized waste materials disposed in the inner shell member, each of said heating assemblies consisting of a pre-heating chamber in communication with said heating chamber, a superheated nitrogen producing means in communication with said pre-heating chamber, and a burner fixedly held on said superheated nitrogen producing means and being arranged such that it is capable of providing flame heat in said superheated nitrogen producing means, pre-heating chamber and heating chamber, said superheated nitrogen producing means being capable of transforming nitrogen contained therein into superheated nitrogen through utilization of heat generated by said burner and facilitates introduction of superheated nitrogen gas into the burner flame in the pre-heating chamber, and hydrocarbon gas line in communication with said waste heating chamber being arranged such that it is capable of allowing the introduction into the burner flame the hydrocarbon gas produced during heating of the waste material within the waste heating chamber.
