「発明が解決しようとする問題点」
以上の様に可熱性の廃プラスチックを熱風で熔融するこ
とは着火する危険があった、低い温度の熱風では安全で
あるが時間を要し能率が上らない欠点があった。``Problems to be solved by the invention'' As mentioned above, melting thermoplastic waste plastics with hot air has the risk of ignition, and while low-temperature hot air is safe, it takes time and does not improve efficiency. There were no drawbacks.
本発明の目的は可燃性の廃プラスチックを着火する危険
がなく安全にしかも高能率に処理する方法を提供するこ
とである。An object of the present invention is to provide a method for safely and highly efficiently processing flammable waste plastics without the risk of ignition.

ど煙は見られない、湿潤熱風を入れたま＼作業を中止し
ても燃え出す事もなく安全である。The melted waste plastic 7 melts and flows into the receiving box 6.
According to experiments, the volume of styrofoam is about 100%, and that of polyethylene sheets is about 100%. The moist hot air is discharged into the atmosphere from a sufficiently high chimney 9. According to experiments, there is almost no smoke in the moist hot air coming out of the chimney 9, and it is safe even if you stop working with the moist hot air in, as there will be no fire.
「発明の効果」
以上の様に本発明の廃プラスチツク熱処理方法は、第一
