Abstract
A recycling system for a waste converting apparatus collects residues from a post-processing means and re-introduces the residues into the apparatus such that the residues are exposed to the high temperature zone thereof.
Claims60
A residues recycling system for recycling at least part of the residues formed in a waste processing plant, said waste processing plant having:
- at least one waste processing chamber adapted for accommodating a column of waste and for enabling said waste to migrate through the chamber in a downstream direction, said chamber having at least one upstream gas outlet means and further having high temperature generating means adapted for providing a high temperature melting zone in a downstream part of said chamber and a relatively cooler upstream gasification zone, wherein said melting zone is at conditions at least sufficient for enabling substantially all inorganic waste therein to be melted into at least one of melted metals and slag, and wherein said upstream gasification zone is at conditions sufficient for enabling gasification of organic waste in said column of waste;
- at least one post processing means operatively connected to said at least one waste processing chamber, wherein said post-processing means are adapted for enabling said residues to be collected therefrom during operation of said at least one waste processing chamber;
- wherein said residues recycling system is characterized in being adapted for introducing at least a portion of said residues into the lower part of said processing chamber such that during operation of said system said portion of said residues is directly exposed to said high temperature melting zone provided by said high temperature generating means.
A method for recycling at least a part of residues formed in a waste processing plant, said waste processing plant having:
- at least one waste processing chamber adapted for accommodating a column of waste and for enabling said waste to migrate through the chamber in a downstream direction, said chamber having at least one upstream gas outlet means and further having high temperature generating means adapted for providing a high temperature melting zone in a downstream part of said chamber and a relatively cooler upstream gasification zone, wherein said melting zone is at conditions at least sufficient for enabling substantially all inorganic waste therein to be melted into at least one of melted metals and slag, and wherein said upstream gasification zone is at conditions sufficient for enabling gasification of organic waste in said column of waste;
- at least one post processing means operatively connected to said waste processing chamber, wherein said post- processing means are adapted for enabling said residues to be collected therefrom during operation of said at least one waste processing chamber;
- wherein said method comprises the steps:
- (a) collecting at least part of said residues from a said post processing means;
- and
- (b) introducing at least part of said residues into a said processing chamber such that during operation of said system said residues are exposed to said high temperature melting zone provided by the said high temperature generating means.
