PURPOSE: To prevent coking on the inner wall of a pipe and to realize a safe stable operation and an improvement in recovery of a produced oil by using the title device having a specified constitution for thermal decomposition of waste material.
CONSTITUTION: The title device consists of a melting chamber 11 for melting waste material, such as a waste oil or a raw polymer; a storage chamber 14 connected to the melting chamber 11 and serving to supply a molten material; a decomposition reactor 1 connected to the storage chamber 14 and having a uniform inside temperature; and a circulation pipe 5 installed in a heating furnace 3 so as to be wound up from the lower part, having on one end thereof a treated material inlet 5a connected to a treated material outlet 1a provided on the lower part of the side wall of the decomposition reactor 1, and having on the other end thereof an outlet 5b connected to a heat-treated material inlet 1b on the upper part of the decomposition reactor 1. Waste material is melted in the melting chamber 11, fed into the decomposition reactor 1 by way of the storage chamber 14, and then sent into the circulation pipe 5 in the heating furnace 3 to treat under prescribed conditions.
