DEVICE FOR TAKING OUT WASTE PLASTIC THERMAL DECOMPOSITION RESIDUE

摘要

PURPOSE: To provide a residue taking out device capable of preventing piling/ sticking of a thermal decomposition residue on a wall face in a thermal decomposition reaction tank for melting/thermally decomposing a waste plastic. CONSTITUTION: A precipitation tank 13 for recovering a thermal decomposition residue is installed through an on-off valve 14 at the bottom of a thermal decomposition reaction tank 11. A nitrogen gas supply pipe 16 for pushing a thermal decomposition residue in the precipitation tank toward a residue outlet 15 is connected to the top part of the precipitation tank 14. Consequently, the thermal decomposition residue can be recovered in the precipitation tank without retaining in the thermal decomposition reaction tank.
