Abstract:
A thermal decomposition apparatus for polymer waste comprising:a first chamber including a receiving section, a fusing sections and a storage section below said fusing section;a second chamber including a primary decomposing section and a secondary decomposing section above said primary decomposing section;a storage region formed at an intersection of said storage section and said primary decomposing section:a first heater for maintaining a temperature of said fusing section between approximately 200.degree. C. and 300.degree. C.;a second heater for maintaining a temperature of said primary decomposing section and said storage region between approximately 300.degree. C. and 400.degree. C.;a third heater for maintaining a temperature of said secondary decomposing section between approximately 400.degree. C. and 500.degree. C.;wherein an upper portion of said secondary decomposing section includes a collecting space communicating with an oil-liquefying device to liquify decomposed gas input from the collecting space.
