The incinerator 110 may be connected to a distillation tower 150 that cools the first gas discharged from the incinerator 110 and classifies it as liquefied fuel. The distillation column 150 may use those known in the art, and the present invention is not limited by the detailed configuration of the distillation column 150. As such, when the incinerator 110 is connected to the distillation column 150, the incineration apparatus according to an embodiment of the present invention is useful in terms of energy and environmental protection. Meanwhile, the incinerator 110 may not be connected to the distillation column 150, and in this case, the incinerator 110 may be directly connected to the gas combustion unit 120.

The gas combustion unit 120 may burn some or all of the first gas discharged from the incinerator 110. For example, the gas combustion unit 120 is connected to the distillation column 150 to burn the second gas in order to receive a second gas not classified as liquefied fuel in the distillation tower 150 among the first gas. You can. Alternatively, the gas combustion unit 120 may burn the first gas while not being connected to the distillation column 150, in which case the incinerator 110 and the gas combustion unit 120 may be directly connected. .

2 is a perspective view for schematically illustrating an incineration apparatus according to an embodiment of the present invention. Figure 3 is a perspective view for explaining in more detail the incineration apparatus according to an embodiment of the present invention. Figure 4 is a side view showing an incineration apparatus according to an embodiment of the present invention.

The incinerator 210 has an accommodating space for accommodating flammable waste, and the front side of the incinerator 210 may be provided with a waste entrance door 212 that can be opened and closed for the input and sealing of the flammable waste. In this case, the combustible waste may be any material that can be burned by a predetermined heat, and thus the present invention is not limited by the kind thereof. For example, the combustible waste may include food waste, synthetic tires such as waste tires, waste vinyl, and various waste oils.

In the incinerator 210, the combustible waste may be incompletely combusted, and the incineration residues remaining after the incomplete combustion may be utilized as a solid fuel. For example, when the synthetic resin or the like containing a large amount of carbon is incompletely burned in the incinerator 210, since the incineration residue contains a large amount of carbon, etc., the incineration residue may be used as a solid fuel.

In order to incompletely burn the combustible waste in the incinerator 210, it is necessary to prevent the air from flowing into the incinerator 210 or to suppress the inflow of the air. And, the temperature inside the incinerator 210 may be 600 to 650 ℃, which may vary depending on the type of flammable waste, that is, the combustion point of the flammable waste, the present invention is not limited to the above.

The incinerator 210 may include a protrusion 214 protruding into the incinerator 210. The protrusions 214 may be formed in plural, and the distance I between the protrusions 214 adjacent to each other may increase from the bottom of the incinerator 210 toward the top of the incinerator 210, but is not limited thereto. For example, the distance I between adjacent protrusions 214 may be smaller or constant from the bottom of the incinerator 210 toward the top of the incinerator 210.

The shelf 216 for loading the combustible waste may be arranged in multiple stages on the protrusion 214. This is to transfer heat more efficiently. That is, since the shelves 216 may be spaced apart from each other by the protrusion 214, heat movement may be smoothly performed between the shelves 216. The shelf 216 may be formed to include a material having excellent heat transfer, for example, a material such as stainless steel. The shelf 216 may be formed in a shape such as a container or a net, and the present invention is not limited by the shape of the shelf 216. On the other hand, in the incinerator 200 according to an embodiment of the present invention, the combustible waste may be directly injected into the incinerator 210 without using the shelf 216.

The gas combustion unit 220 may be disposed to surround sidewalls of the incinerator 210. The gas introduced into the gas combustion unit 220 through the gas inlet 222 may move along the movement path as shown in FIG. 5 and be discharged through the second gas outlet 224, but the gas combustion may be performed. Since the arrangement structure of the unit 220 and the gas flow path may be variously changed according to a required condition and a design environment, the present invention is not limited to the above. FIG. 5 is a view for explaining a path in which gas moves in the gas combustion unit illustrated in FIG. 3.

The temperature inside the gas combustion unit 220 may be 800 to 850 ° C. Accordingly, since the gas may be completely burned while passing through the gas combustion unit 220, the emission of various harmful gases including carbon dioxide may be minimized. For smooth gas movement in the gas combustion unit 220, the pressure inside the gas combustion unit 220 may be maintained at, for example, 0.01 to 0.5 atmospheres.

The heat supply unit 230 may supply heat to the incinerator 210 and the gas combustion unit 220. The position at which the heat supply unit 230 is disposed is not particularly limited, but may be disposed in the gas combustion unit 220 in consideration of energy saving aspects.

FIG. 6 is a view for explaining the heat supply unit illustrated in FIG. 3 in more detail.

Referring to FIG. 6, the heat supply unit 230 may include a heat supply body 232 and a heating coil 236.

A body through-hole 234 may be formed in the heat supply body 232 along the heat supply body 232 in the longitudinal direction, that is, along the gas movement direction in the gas combustion unit 220. This is to induce gas moving through the gas combustion unit 220 to pass through the body through hole 234. The body through-hole 234 is formed relatively large so as to smoothly induce the gas inflow at one end into which the gas is introduced, and relatively narrow to suppress the load by the heating coil 236 at the other end through which the gas is discharged. Losing may be formed to have a shape.

The heating coil 236 may be wound around the outer circumferential surface of the heat supply body 232. The heating coil 236 may receive power from the outside to emit heat using the power.
