Description

Mobile fuel recovery device and its method {MOVABLE APPARATUS AND METHOD FOR EXTRACTING FUEL FROM WASTE PLASTIC AND WASTE OIL}

The present invention relates to a mobile fuel recovery device and a method thereof, and to a gasoline and diesel engine at low cost and high yield using a low-temperature pyrolysis reaction without using a catalyst from waste plastic and waste oil through a small device that can be moved in more detail. The present invention relates to a mobile fuel recovery apparatus and a method for recovering oil such as oil and recovering sludge (residue or waste) generated during the continuous process to be used as fuel in a combustion furnace.

As is well known, the molecular weight of plastics generally ranges from 1.0 × 10 ^{5 to} 1.0 × 10 ⁶ , and when the waste plastic is heated, the waste plastic is a mixture of low molecular weight materials such as gasoline, diesel oil, heavy oil, gas and the like. Is crushed into.

At this time, the thermal grinding conditions are made at a low temperature, low pressure of the liquid phase, the grinding reaction is a reaction without a catalyst.

Catalysts are used in other processes for treating waste plastics with fuel oil, and catalytic processes for the crushing of waste plastics are not possible. Because the molecular weight of the plastic is too large or the molecular volume is too large, the catalyst crushing reaction on the waste plastic is impossible due to the surface area of the catalyst because the plastic is introduced into the inner surface of the catalyst when reacting with the catalyst.

With the development of modern civilization, the plastics industry is developing, and the amount of plastics discarded is increasing exponentially. Therefore, plastics have to be treated, but due to the nature of the material, incineration occurs during the incineration process, it does not rot very well, especially because it is often used as a disposable product is too much waste of resources just to handle.

As more plastics are discarded as described above, their recycling methods are continuously researched, and the most prominent among them is a method of recycling waste plastics into various gases or oily hydrocarbons.

Conventional emulsification processes for waste plastics include thermal (catalytic) decomposition and invented methods developed in Japan. However, these methods are mainly for emulsifying thermoplastic resins, but also for kinds of resins which cannot be treated (for example, polyethylene terephthalate, polyvinyl chloride, etc.) for thermal catalytic decomposition. Of course, there is a high possibility of secondary pollution caused by the process, and the working process has not been performed continuously until now, and in the case of most plastic emulsifiers, the scale is a large unit of a plant unit, and the cost increases, The problem is that it is not enough to be installed in a small apartment complex.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described prior art, and consists of a single reactor and a combustion furnace, and integrates a distillation column connected from the reactor to extract fuel such as gasoline and diesel from waste plastic and waste oil. It is an object of the present invention to provide a small portable fuel recovery apparatus and method thereof.
