Description of the Related Art In recent years, synthetic resins such as plastics have been increasing as industrial wastes and general wastes, and their disposal has become a serious social and environmental problem. Plastics, which are high-molecular hydrocarbon compounds, generate a large amount of heat when they are burned, and require special incineration equipment due to problems such as damage to the walls of incinerators when incinerated. Currently, it is disposed of in landfills. However, dumping of plastics and the like causes deterioration of the landfill, and is not preferable in terms of environmental measures.
Further, in recent years, the shortage of land for landfills has become a social problem along with the increase in disposal costs, and therefore development of a method for mass processing of synthetic resins without dumping is keenly desired. In particular, the recycling of metal-composite waste plastics containing these plastics, such as scrap cars and household electrical appliances, has been called for to recycle resources, and the treatment has become a social problem.

現在は埋め立て処分されている。Conventionally, as a method of treating this metal-composite waste plastic, in the case of a scrapped vehicle, valuable parts such as an engine, a battery, and an exhaust gas treatment catalyst are disassembled and separated, and then other waste is pulverized with a shredder. A method of recovering iron from a crushed material by a magnetic separator and aluminum by an aluminum separator is adopted. Although copper such as motors and wire furnaces is collected by hand, the recovery rate is low. Plastics contained in end-of-life vehicles are glass and rubber,
About 30% of the waste is discharged as dust along with the fibers. A similar treatment method is used for waste home appliances. Since this dust contains useful substances including plastics, various studies such as mechanical separation method and gasification melting treatment have been made, but the separation method has not been established,
It is currently being landfilled.

重質油が望ましく用いられる。The material used as the heat medium exists as a liquid at the immersion temperature of the composite waste, and does not contain harmful components such as alkali salts which are harmful when the separated metal is melted.
It also becomes a reducing material and fuel for blast furnaces. In addition, at this immersion temperature, it is necessary that physical properties such as viscosity do not change at least with little decomposition, and that separation from separated metals and other inorganic materials is easy. Further, it is desirable that the separated polymer floats and separates from the heating medium. Those satisfying these conditions have a boiling point of 250 ° C. or higher and an aromatic index of 0.2 or higher. Preferably, the boiling point is at least 300 ° C, particularly preferably at least 350 ° C. On the other hand, the upper limit of the boiling point is determined from its thermal stability and is 600 ° C. or less, especially 550 ° C.
It is preferable that the temperature is not higher than ° C. The aromatic index is the ratio of the number of aromatic carbon atoms to the total number of carbon atoms, and is expressed as Brown-Lad.

The immersion temperature and the time vary depending on the type and amount of the polymer, but are about 200 to 400 ° C., preferably 250 to 350 ° C. About 0.5 to 30 minutes, preferably about 1.5 to 15 minutes is appropriate.

It is better to use steam for cleaning. This device also preferably has a structure that can shut off the inside from the outside air. Since the washed liquid is a mixture of a heat medium and water, the heat medium can be recovered by an oil-water separator or the like and circulated to the heat treatment tank.

を採用することも可能である。In addition to the processing apparatus described above, a crushing step for crushing the collected metal composite waste plastic into two to ten parts is provided. Conventionally, a guillotine or a crusher used for cutting waste containing metal can be used for cutting. In addition, since the surface of the waste is cracked by performing the main pulverization step in the first processing step, deaeration to remove oxygen contained in metal-composite waste plastic is performed to prevent the generation of harmful substances such as dioxin. In addition to easy removal of oxygen in the process, the molten liquid also easily penetrates in the subsequent heat treatment step, making it easier for metal-composite waste plastic to come into contact with the molten liquid. Collection becomes easy. The degree of division varies depending on the size, composition, and structure of the metal-composite waste plastic, but in the case of scrapped cars and waste home appliances, it is divided into two or more, preferably three or more and up to about ten. If it is larger than this, the guillotine fixed blade and the push-cutting blade become worn and the power thereof increases. Further, the obtained divided material also has an increased bulk density and becomes difficult to handle, and it becomes gradually difficult to remove the molten liquid after the treatment. It is also possible to employ a press for pressing and using the collected metal for refining the metal.
