Description

Pyrolysis and emulsification equipment to prevent gas leakage considering the rotation and expansion of the pyrolysis furnace {PYROLYSIS PETROLIZING APPARATUS FOR PREVENTING GAS LEAKAGE CONSIDERING ROTATION AND THERMAL EXPANSION OF PYROLYSIS REACTOR}

The present invention relates to a pyrolysis and emulsification device, and more particularly, to a pyrolysis and emulsification device for preventing gas leakage considering the rotation and expansion of a pyrolysis furnace that produces recycled oil by pyrolyzing polymer waste such as waste plastic and vinyl by heating. About.

Currently, plastics and vinyls, which are polymer materials composed of hydrocarbons used for various purposes, have increased emissions due to industrial development, and are mostly treated by incineration and landfill, causing serious environmental pollution such as air, soil, and oceans. As it emerges as a result, the development of new treatment technology for polymer waste is required.

In addition, various methods for cyclical use of resources are being devised, and thus, an emulsification device technology that recycles various types of waste plastics is being activated. As an example, it is a method of recycling polymer wastes such as waste plastics and vinyls manufactured using petroleum as a raw material. By applying heat in a reducing atmosphere without oxygen, it causes a decomposition reaction in which the carbon chains constituting the polymer are broken and changes into several low-molecular substances. As the waste is dissolved and gasified, it is liquefied through a cooling device to obtain recycled oil again. Some hydrocarbons break their bonds even at 200℃, and when the temperature is raised to 350~400℃, violent pyrolysis occurs.

These emulsification devices include a batch type in which waste is heated and melted from the outside while being charged in the pyrolysis furnace, and a continuous type in which waste is continuously put into the pyrolysis furnace and heated from the outside while continuously pyrolysis.

Referring to FIG. 1 as a related art, in Patent Document 1, it is arranged horizontally and rotates by the rotational force provided by the motor 13, and the injected waste plastic and waste vinyl are stirred with a solvent by a spiral 11 formed on the inner circumferential surface. A cylindrical heating furnace 10 that heats the furnace, and a separation device 20 for separating the gas discharged from the discharge pipe 12 connected to the outlet side of the heating furnace 10 into heavy oil gas and light oil gas, and a separation device 20 The cooling device 30 for cooling and liquefying the diesel gas separated by the cooling device 30, the gas storage unit 40 for storing and liquefying the gas cooled by the cooling device and the diesel, and the gas that is not liquefied by the gas storage unit. A gas supply unit 50 for resupplying to the heating furnace, a combustion gas outlet 60 for discharging the combustion gas of waste to the outside of the heating furnace 10, and a dust collector ( 70), and an exhaust fan 80 for discharging the combustion gas that has passed through the dust collector 70 to the outside.

However, since it is composed of a structure in which the high-temperature combustion heat is supplied to the inside of the heating furnace, a large temperature difference occurs, so a large length deformation occurs due to thermal expansion and contraction of the heating furnace. If the heating furnace repeats thermal expansion and contraction while being installed in a fixed state and repeating the operation and stop of pyrolysis, damage due to cracks and deformation may occur, and the pipe may be ruptured or separated. Large-scale safety accidents may occur in which gas and oil vapors are leaked to the outside due to roaring noise or cracks.

In addition, the above-described prior art is cumbersome and difficult to separate the input means and the pyrolysis furnace, and it is difficult to fine-tune the input depth, height, and horizontality of the input pipe suitable for each device, and it takes a considerable amount of work time and maintenance. And there is a problem that the inspection is inefficient.
