<p>PROBLEM TO BE SOLVED: To prevent the overheating of waste plastics generated by a heating medium and effectively utilize the energy of the heating medium to efficiently heat the waste plastics. SOLUTION: A waste plastic heat decomposition device is provided with an inner container 11 storing waste plastics and an outer container 12 encircling the inner container 11 and having a flow inlet 15 and a flow outlet 16 for a heating medium. The heating medium from a heating medium feeder 30 is introduced from the flow inlet 15 into the outer container 12 through an adjustment mechanism 31. The heating medium introduced into the outer container 12 flows from a parting wall 13 into a flow path A inside to efficiently heat the inner container 11. Then the heating medium is discharged from a flow path B through the flow outlet 16. During the above process, the adjustment mechanism 31 is controlled by a control device 32 based on signals from a thermometer 34 set on the inner container 11 to prevent the overheating of the inner container 11.</p> |
