NOVELTY - A waste recycling system comprises heated enclosure. Input conveyor(s) introduces waste particles to the enclosure, provides temperature gradient along a flow line, and mechanically moves waste particles and residual solids along the flow line. A heated rotary drum is connected with the flow line. A condenser receives vapor from the flow line and rotary drum and outputs hydrocarbons. Discharge conveyor(s) discharges residual solids. Control valves seal vacuum downstream from input conveyors and upstream from discharge conveyors. A vacuum pump maintains vacuum between control valves.    USE - System for recycling waste including rubber particles from tires, solid waste, sewage sludge, animal waste, trash and refuge, solid industrial waste, and coal or other solid fossil fuel into energy. Can also be used for converting waste plastics and waste fat from animals, fryer oils and other food processing wastes into useful products; and for producing valuable by-products from waste materials, including cleaners, solvents, and other valuable chemicals used in different industrial, oilfield, and pipeline operations.    ADVANTAGE - The system avoids the problems of prior attempts to efficiently convert waste material into energy by avoiding the requirement of fluidized bed or other special reactions. The system is compact and can be placed in a small location, with the emissions from the system being clean and non-hazardous. By providing a system which is operating under vacuum, inadvertent release of gases is minimized, while the vacuum pump draws hydrocarbon vapor in counter flow direction from the particles toward the condenser units. The system does not require specialized equipment, but utilizes components which are readily available from a variety of sources.    DETAILED DESCRIPTION - A waste recycling system comprises a heated enclosure having an interior chamber and internal baffles within the heated chamber, and input conveyor(s) for inputting waste particles to the heated enclosure. The input conveyor has a flow line positioned with respect to the baffles to provide a temperature gradient of greater than or equal to 150 degrees F along the flow line, producing hydrocarbon vapor and residual solids. The input conveyors mechanically move the waste particles and residual solids along the flow line. A heated rotary drum is connected with an exit from the flow line for receiving waste particles and residual solids from the flow line. The rotary drum has an interior temperature of 730-800 degrees F for generating hydrocarbon vapor and residual solids. A condenser is connected with the flow line and rotary drum for receiving vapor from the flow line and rotary drum and outputting hydrocarbon liquids and hydrocarbon gas. Discharge conveyor(s) discharges residual solids from the rotary drum. At least two input control valves seal vacuum downstream from the input conveyors. At least two discharge control valves seal vacuum upstream from the discharge conveyors. A vacuum pump maintains selected vacuum between the two input valves and the two discharge valves so that hydrocarbon vapor is drawn from the flow line and rotary drum into the condenser.    DESCRIPTION OF DRAWING(S) - The drawing is a schematic view of a waste recycling system.
