Definitions
- the present invention relates to an apparatus for decomposing waste plastic and collecting it as fuel oil or fuel gas. Background technique
- waste plastics when incinerated, generate high temperatures and damage the incinerator, and are being sought as waste disposal methods that are difficult to dispose of.
- many waste plastics for example, polyethylene and polystyrene, can be converted into a liquid phase polymer by performing a thermal decomposition treatment, and can be recovered as fuel oil or fuel gas by further thermal decomposition. Since the recovery of these useful materials from waste is the best means of waste treatment, the development of equipment that can recover fuel oil and fuel gas from waste plastics at a reasonable cost is desired.
- This carbon covers the heated surface and acts as a thermal insulator, so it separates from the liquid phase polymer. This makes it difficult to control the solution, especially the decomposition temperature, and increases the running cost of the decomposition equipment. Also, if this carbon is mixed into the recovered oil, the oil quality will be reduced. In addition, it is difficult to control the degree of decomposition of the liquid-phase polymer because it is difficult to keep the temperature of the entire liquid-phase polymer uniform during the decomposition reaction. There is also a problem that it is difficult to obtain.
- an object of the present invention to provide a method for separating a vaporized component generated from a liquid-phase polymer from the liquid-phase polymer quickly and efficiently, thereby suppressing the generation of carbon accompanying the decomposition reaction, and reducing the temperature of the entire liquid-phase polymer.

In the reaction space formed between the inner surface and the outer surface of the rotating body, the liquid polymer flowing down is raised by a screw and thermally decomposed while stirring.
