US 2011/0079171 A1 · APPARATUS FOR TREATING WASTE

Abstract

A waste treatment system processes waste upon the application of energy. The system includes a vessel that contains an open space. A waste feed system feeds inorganic and/or organic waste into the open space of the vessel. One or more pairs of electrodes are within the vessel and may be supported above a bottom of the vessel. The electrodes generate energy that heats the vessel's open space, and melts inorganic portions of the waste and gasifies and dissociates organic portions of the waste into elemental components. These elemental components may be reformed into a synthesis gas which may be conditioned and cleaned to recovery a non-hazardous product.

Dependent claims

A system to treat waste, comprising:

a vessel that contains an open space and a slag area, the slag area comprising a bottom portion of the vessel that is configured to retain melted inorganic waste;
a waste feed system operable to feed a waste into the open space of the vessel;
an anode extending into a lower portion of the vessel and supported above the slag area;
a cathode extending into the vessel and positioned opposite and in-line with the anode;
a quenching system configured to cool a gas output from the vessel, the quenching system in communication with the vessel;
a spray dryer system configured to introduce a liquid to remove a portion of a particulate from a gas output from the quenching system;
and
a carbon injection system configured to inject carbon into a gas output from the quenching system.
