APPARATUS FOR TREATING WASTE POLYMER

WIPO Patent Application WO/2007/148402

A1

[PROBLEMS] To continuously treat a waste polymer and to heighten heat efficiency during operation and shorten cooling time. [MEANS FOR SOLVING PROBLEMS] An apparatus which comprises: pyrolysis ovens (1) and (2) for pyrolyzing a waste polymer (WP) with a high-temperature gas; an oil recovery part (3) for recovering an oil matter from the gas which has passed through the pyrolysis ovens (1) and (2); a heat exchanger (6) for heating to a high temperature the gas which has passed through the oil recovery part (3); and gas channels for circulating the gas through the pyrolysis ovens (1) and (2), oil recovery part (3), and gas-heating part (6). Channel switches (41) and (42) for switching the gas channels are disposed between the pyrolysis ovens (1) and (2) and the oil recovery part (3) and between the pyrolysis ovens (1) and (2) and the heat exchanger (6), respectively. One of the pyrolysis ovens (1) and (2) is selected and the gas channels are switched accordingly.
