The present invention relates to a waste incineration apparatus, and in particular, it heats the wastes without directly burning the wastes, vaporizes the carbonized material of the wastes with a well-burned gas, and burns the wastes by incineration of the wastes. The present invention relates to a waste incineration apparatus capable of minimizing the emission of hazardous substances and saving energy by heating wastes.

As the demand for automobiles increases along with industrial development and the improvement of people's standard of living, the amount of waste is also rapidly increasing, and the disposal of such waste is enormous cost, and there is concern about serious environmental destruction caused by the treatment. In other words, the disposal of waste is largely divided into incineration, landfilling, and recycling. As the most efficient method in terms of environment, the recycling of waste is preferable, but the recycling of waste is extremely limited. In contrast, incineration and landfilling of wastes have the advantage of easy processing and low cost.

However, the landfill of waste requires a large area of landfill, and the pollution of soil and groundwater is pointed out as a big problem due to the contaminants generated from waste after landfill.

Another method, waste incineration, involves the consumption of fuel, and there is a great concern for air pollution due to dust and waste gases, including harmful substances generated during incineration. Although these problems are expected, it is difficult to secure sufficient landfills in a narrow land area, so our country currently relies heavily on incineration of waste.

In general, the waste incineration is a dry distillation incineration method, which completely burns the carbonized carbon gas generated in the incineration process in the secondary combustion chamber, and requires a large amount of fuel to completely burn the carbonized combustion gas. There is this.

The present invention is to solve the above problems, the purpose of the present invention is to heat the waste to vaporize the combustible gas, and burn the vaporized carbonized gas to use the heat of combustion to heat the waste can save energy In addition, the present invention provides a waste incineration apparatus capable of suppressing the emission of harmful substances such as dioxins by mixing and burning air with the generated carbonized gas.

Waste incineration apparatus according to the present invention to achieve the above object, the input hopper for injecting the crushed waste, the cylindrical shape, the lower inlet is provided with an inlet connected to the inlet hopper, the lower outlet side An incinerator having an exhaust port at an upper portion thereof, a conveying means having a conveyor installed at a lower portion of the incinerator so as to transfer waste introduced into the input hopper from an inlet of the incinerator to a discharge port of the incinerator at a predetermined speed; A discharging head for discharging air from the upper part of the incinerator to the upper part of the conveyor, the air supply means having a pump for supplying air through a conduit to the discharging head; A burner is provided for heating the air and burning the gas mixed with the air. do.

The waste conveyed by the conveyor is heated in the incinerator preheated by the burner to vaporize carbonized gas from the waste. The vaporized carbonized gas is combusted while being mixed with oxygen discharged into the incinerator by the air supply means. Therefore, the present invention has the advantage of minimizing the emission of harmful substances by burning the vaporized carbon gas without directly burning the waste. In addition, the present invention can reduce the energy consumption for the heating and combustion of the waste because the waste is heated by the combustion heat generated when the carbon gas is burned.

In addition, in the waste incineration apparatus according to the present invention, the discharge head is extended in the horizontal direction from side to side based on the center of the incinerator so that the rotary flow is formed in the incinerator by the air discharged from the discharge head and the discharge port is Characterized in that arranged side by side in the horizontal direction from the opposite direction relative to the center of the discharge head, respectively.

Since the air discharged from the discharge head is rotated in the cylindrical incinerator, a rotational flow is formed in the incinerator. At the same time, as the carbonized gas mixed with the air is combusted, an upward flow is formed, and the combustion gas is discharged while the whirlwind is formed inside the incinerator by the upward flow of the rotary flow.

In addition, in the waste incineration apparatus according to the present invention, the discharge head is characterized in that the number is provided to cross each other at different heights.

Accordingly, since the discharge of air is made from the discharge head provided with different heights up and down, the discharge of air and the formation of rotational flow are actively performed.

Hereinafter, the waste incineration apparatus according to the present invention will be described in more detail with reference to the embodiment shown in the drawings.

1 is a cross-sectional view conceptually showing a waste incineration apparatus according to an embodiment of the present invention.

Referring to the drawings, the waste incineration apparatus according to the present invention comprises an input hopper (1), an incinerator (2), a conveying means (3), an air supply means (4), and a burner (5).

The input hopper 1 is for injecting the crushed waste (T), the injected waste (T) is introduced into the inlet 21 of the incinerator (2) is incinerated by the conveyor 31 of the transfer means (3) ( 2) is transferred to the inside.

The incinerator 2 forms a space for injecting the waste T injected therein and blocks contact with external air other than the air supplied by the air supply means 4. The incinerator 2 is formed in a cylindrical shape so that the rotational flow is well formed therein. An inlet 22 connected to the inlet hopper 1 is provided at one lower side of the incinerator 2, and an outlet 22 is provided at the other lower side opposite to the inlet 21. And the upper part of the incinerator (2) is provided with an exhaust port 23 for discharging the exhaust gas (G3) generated by the incineration of the waste (T). In the lower part of the incinerator 2, a conveyor 31 of the transfer means 3 for transferring the waste T introduced into the inlet 21 to the outlet 22 is installed. The waste T is loaded on the conveyor 31 and heated while passing through the inside of the incinerator 2. The incinerator 2 is preheated by the burner 5 and is heated by the combustion heat generated while the carbonized gas G1 vaporized from the heated waste T is burned while being mixed with air. The inside of the incinerator 2 should be heated enough to vaporize most of the carbon gas G1 from the waste T carried on top of the conveyor 31, and to a temperature that is too high so that the waste T does not burn directly. It must be maintained at a suitable temperature so that it is not heated. For example, when the waste tire, which is one of the representative wastes, is incinerated, the temperature inside the incinerator 2 is preferably about 800 ° C. As described above, the carbonized gas G1 is vaporized while passing through the inside of the incinerator 2, and the remaining waste ash A is discharged to the discharge port 22, flows through the inclined surface 61, and is collected through the gate 62. Discharged to (63). On the other hand, when the burner 5 for preheating the incinerator 2 and burning the vaporized carbon gas G1 is installed in the incinerator 2, air is supplied to the incinerator 2 and discharged. An air supply means 4 is installed on the conveyor 31 of the transfer means 3.

The transfer means 3 is for transferring the waste T introduced into the input hopper 1 from the inlet 21 of the incinerator 2 to the outlet 22 of the incinerator 2 at a predetermined speed. . The conveying means (2) is a lower portion of the incinerator (2) from the inlet 21 to the discharge port 22 is installed long and the drive unit for driving the conveyor 31 (not shown in the figure) And a controller (not shown) for controlling driving. The conveyor 31 is controlled to a feed rate so that most of the carbonized gas (G1) is vaporized from the injected waste (T). On the other hand, the waste (T) carried on top of the conveyor 31 is preferably agitated so that the carbonization gas (G1) is evaporated while sufficiently carbonized, for this purpose, the waste carried on top of the conveyor (31) It is preferable that stirring means (not shown in the figure) for stirring T) is provided inside the incinerator 2.

The air supply means 4 is for supplying air from the top of the conveyor 31 to the interior of the incinerator (2). The present invention is supplied so that the air supplied into the incinerator 2 by the air supply means 4 does not come into contact with the waste T so that the waste T carried on the conveyor 31 is not directly burned. Should be. Therefore, the discharge head 41 installed in the incinerator 2 is installed on the conveyor 31. A pipe line 43 is connected to the discharge head 41, and air is supplied from the outside of the incinerator 2 by the pump 42 through the pipe line 43. The air blown into the discharge head 41 is discharged into the incinerator 2 through the discharge port 411 formed in the discharge head 41. Figure 2 is a perspective view showing the discharge head of the waste incineration apparatus according to an embodiment of the present invention. Referring to the drawings, the discharge head 41 is provided so that several dogs vary in height and cross each other. On the other hand, the discharge head 41 has a structure such that the rotary flow (S) is formed in the incinerator 2 by the air (W) discharged therefrom. That is, the discharge head 41 extends horizontally from side to side with respect to the center of the incinerator 2, and the discharge ports 411 are arranged side by side in the horizontal direction in opposite directions with respect to the center of the discharge head 41, respectively. Array is formed. Accordingly, the air W discharged to the discharge port 411 of the discharge head 41 flows while rotating in one direction in the incinerator 2 having a cylindrical shape, and thus, the rotary flow S in the incinerator 2. Is formed. The carbonized gas G1 generated and raised inside the incinerator 2 by the rotational flow S as described above is mixed well with the air W discharged from the discharge head 41, and thus the carbonized gas. (G1) is well burned. On the other hand, since the gas heated by the combustion rises, the inside of the incinerator 2 generates a tornado by the rotational flow S and the upward flow, and the exhaust gas G3 that is burned and discharged in the incinerator 2 is exhausted. It is discharged at a high speed through 23.

The burner 5 is for heating the inside of the incinerator 2 in advance in a state where the inside of the incinerator 2 is cooled. The carbonized gas 2 vaporized in the heated incinerator 2 is combusted while being ignited by the temperature in the incinerator 2 when mixed with the air W (G2). Nevertheless, the burner 5 is assisted to completely burn the carbonization gas G1, and its operation is controlled so that the temperature inside the incinerator 2 maintains an appropriate temperature (800 ° C). In order to control the burner 5 for maintaining the temperature as described above, a temperature sensor is provided inside the incinerator 2.

By the above configuration, the waste incineration apparatus according to the present invention can not only save energy by heating the waste to vaporize the combustible gas, and burn the vaporized carbonized gas to use the combustion heat for heating the waste. By mixing air with the generated carbonized gas and burning it, it is possible to suppress the emission of harmful substances such as dioxins.
