Abstract

A multi-waste processing system includes a processing chamber. The processing chamber includes one or more heaters and a piston, and the processing chamber is configured to evaporate liquid waste and compact solid waste input. A condenser is operably connected to the processing chamber. The condenser is configured to condense water from the evaporated liquid waste output from the processing chamber. A gas and water separator is operably connected to the condenser. The gas and water separator is configured to separate water from the evaporated liquid waste output from the processing chamber. A recirculation pathway connects the gas and water separator to the processing chamber to recirculate gas from the gas and water separator to the processing chamber. The piston is actuated to keep the one or more heaters in close proximity to the solid waste and the liquid waste in the processing chamber.

First claim

What is claimed is:

1. A multi-waste processing system, comprising:
a processing chamber, the processing chamber including one or more heaters and a piston, the processing chamber configured to evaporate liquid waste and compact solid waste input;
a condenser operably connected to the processing chamber, the condenser configured to condense water from the evaporated liquid waste output from the processing chamber; and
a gas and water separator operably connected to the condenser, the gas and water separator configured to separate water from the evaporated liquid waste output from the processing chamber; and
a recirculation pathway connecting the gas and water separator to the processing chamber to recirculate gas from the gas and water separator to the processing chamber;
wherein the piston is actuated to keep the one or more heaters in close proximity to the solid waste and the liquid waste in the processing chamber.

2. The multi-waste processing system of claim 1 , further comprising a water collector operably connected to the gas and water separator.

3. The multi-waste processing system of claim 1 , further comprising a vacuum pump operably connected to the processing chamber to reduce a pressure inside the processing chamber thereby reducing a boiling point of the liquid waste.

4. The multi-waste processing system of claim 1 , wherein the one or more heaters are configured to sterilize the compacted solid waste.

5. The multi-waste processing system of claim 4 , wherein the processing chamber is configured to produce geometrically stable compacted solid waste.

6. The multi-waste processing system of claim 1 , wherein the piston is driven by one of a linear actuator or a screw drive.

7. The multi-waste processing system of claim 1 , further comprising a vent to dispose of or collect processed gas.

8. The multi-waste processing system of claim 1 , further comprising a catalytic oxidation reactor thermally integrated with the processing chamber.

9. The multi-waste processing system of claim 1 , further comprising:
a compressor configured to compress processed gas; and
an accumulator to store the compressed processed gas.

10. The multi-waste processing system of claim 1 , wherein the solid waste is compacted greater than 80%.

11. The multi-waste processing system of claim 1 , wherein a heater of the one or more heaters is disposed in the piston.

12. A method of multi-waste processing, comprising:
inputting a volume of solid waste and a volume of liquid waste into a processing chamber;
heating the processing chamber via one or more heaters to evaporate the liquid waste therein;
outputting the evaporated liquid waste in gas phase to a condenser from the processing chamber;
condensing liquid water from the evaporated liquid waste in gas phase at the condenser;
separating water from gas at a gas and water separator downstream of the condenser;
directing gaseous products of the gas and water separator to the processing chamber via a recirculation line;
compressing processed gas at a compressor; and
storing the compressed processed gas at an accumulator.

13. The method of claim 12 , further comprising compacting the solid waste at the processing chamber via actuation of a piston at the processing chamber.

14. The method of claim 13 , wherein the compacted solid waste is geometrically stable.

15. The method of claim 13 , wherein the solid waste is compacted greater than 80%.

16. The method of claim 12 , further comprising collecting the condensed water at a water collector.

17. The method of claim 12 , further comprising reducing a pressure inside the processing chamber thereby reducing a boiling point of the liquid waste.

18. The method of claim 12 , further comprising disposing of a processed gas via a vent.

19. The method of claim 12 , further comprising treatment of the gas via catalytic oxidation in a reactor that is thermally integrated with the processing chamber.
