Abstract

A waste treatment system processes waste upon the application of energy. The system includes a vessel that has an open space that receives waste feedstock. At least two plasma electrodes are mounted to the vessel. An electrode movement control system may position the plasma electrodes to facilitate a pryolysis process to treat the waste feedstock.

Claims (18)

1. A waste treatment system, comprising:

a vessel, the vessel having an open space that receives waste feedstock;

at least two plasma electrodes, each extending into the vessel; and

an electrode movement control system that is configured to automatically move along different axes a first plasma electrode and a second plasma electrode, from the at least two plasma electrodes, a distance mart from each other to produce a substantially constant temperature within the open space of the vessel to facilitate a pyrolysis process to treat the waste feedstock.

2. The system of claim 1 , further comprising a waste feed system coupled to the vessel.

3. The system of claim 2 , where the waste feed system comprises a solid waste feed system.

4. The system of claim 2 , where the waste feed system comprises a liquid waste feed system.

5. The system of claim 1 , where one of the at least two plasma electrodes is mounted through a top of the vessel.

6. The system of claim 1 , where one of the at least two plasma electrodes is mounted through a side of the vessel.

7. The system of claim 1 , further comprising a secondary chamber where synthesis gas output by the vessel is transformed into nitrogen, oxygen, carbon dioxide, or water vapor.

8. The system of claim 1 , where the electrode movement control system is further configured to adjust the distance between the first plasma electrode and the second plasma electrode when an operation voltage between the first plasma electrode and the second plasma electrode fluctuates beyond a predetermined threshold band.

9. The system of claim 8 , where the distance between the first plasma electrode and the second plasma electrode comprises a range between about 10 millimeters to about 75 millimeters.

10. The system of claim 8 , where the predetermined threshold of operation voltage comprises a value between about 80 volts to about 120 volts.

11. The system of claim 1 , where the first plasma electrode and the second plasma electrode produce heat to dissociate organic molecules of the waste feedstock into elemental components.

12. The system of claim 11 , where the vessel comprises a reduced atmosphere as compared to a secondary chamber, positioned downstream of the vessel.

13. The system of claim 1 , where the first plasma electrode and the second plasma electrode produce heat to melt inorganic constituents of the waste feedstock.

14. The system of claim 1 , where the at least two plasma electrodes comprise graphite.

15. The system of claim 1 , where the electrode movement control system is further configured to independently move the first plasma electrode and the second plasma electrode.
