PROBLEM TO BE SOLVED: To provide a waste plastic treatment device, which can improve an energy efficiency as a whole by a method wherein the exhaust gas from a deodorizing oven is contrived to be effectively utilized. SOLUTION: This waste plastic treatment device is equipped with a thermal cracking tank 6, which produces oil vapor through the thermal cracking oleaginous treatment of waste plastics, and a product oil recovering tower 7, through which the oil vapour from the thermal cracking is guided for distillation and produced product gas. The product gas from the product oil recovering tower 7 is introduced into the deodorizing oven 12 and fired. The combustion exhaust gas from the deodorizing oven 12 is sent to the thermal cracking tank 6 and the product oil recovering tower 7 so as to heat the thermal cracking tank 6 and the product oil recovering tower 7. |
