Abstract
The present invention provides methods and apparatus for treating waste, such as municipal waste via pyrolysis and yielding one or more of heat energy, electrical energy and fuel. In some embodiments, waste feed stock can be municipal waste in black bag form. In some the present invention additionally provides for processing of thousands of tons of municipal waste each day.
Claims4
A pyrolysis apparatus for treating municipal waste, the apparatus comprising:
- an autoclave in which municipal solid waste is pretreated via heating to a temperature of between 400° C. and 600° C. to generate pretreated municipal waste;
- a heated multi zoned pyrolysis muffle chamber proximate to the autoclave for receiving the pretreated municipal waste via an ingress passage, the pyrolysis muffle chamber comprising individual control zones for efficient application of thermal energy to the pyrolysis muffle chamber and gas off take ports for each individual control zone;
- wherein said pretreated municipal waste passes through said pyrolysis due to gravitational force and exits via an exit passage;
- multiple radiant heating tubes within the pyrolysis muffle chamber for providing thermal energy within the pyrolysis muffle chamber;
- one or more heat sources for providing thermal energy to the radiant tubes and the pyrolysis muffle chamber, wherein said thermal energy is sufficient to promote pyrolysis of the pretreated municipal waste within the pyrolysis muffle chamber;
- one or more cooling chambers for receiving synthetic gas from the gas take off ports, said cooling chambers comprising water cooled panels wherein said cooling chambers accelerating cooling of the synthetic gas for condensing of tars and oils from said synthetic gas;
- and
- a gas scrubber to scrub the synthetic gas.
