PURPOSE: A pyrolysis device for waste taking an indirect heating method prevents the breakage of sealing state, solving the problem caused by the collapse of vacuum condition of a pyrolyzing furnace. CONSTITUTION: A pyrolysis device for waste taking an indirect heating method has a pyrolyzing furnace with a screw wing (31) installed inside a furnace (10). In order to retain sealing state by using a fluid for cooling to reduce the temperature change, a seal retainer (50) is interposed between a screw axis and a driving device (40) for rotating the screw axis. The pyrolysis device pyrolyzes waste by taking the indirect heating method under the condition of high temperature and vacuum sate. |
