Abstract

PURPOSE:To eliminate the smoke and odor of a combustion gas which is generated from waste in a short period of time by a method wherein a heating element in which a combustion gas stays, and through which the combustion gas can flow to a gas combustion chamber is provided, and the temperature of the combustion gas is raised. CONSTITUTION:In an incineration furnace main body 1, a primary combustion chamber 2 to incinerate waste, secondary combustion chamber 3 and tertiary combustion chamber 4 which are gas combustion chambers to burn a combustion gas generated from the combustion chamber 2 are provided in order from the bottom in such a manner that they communicate with each other. Then, gas retention chambers 5 and 6 which communicate with respective combustion chambers are provided. In the secondary combustion chamber 3 and tertiary combustion chamber 4, a heating plate 10 to be confronted with burners 8 and 9 is provided. The heating plate 10 is a mesh-form object with a honeycomb structure, for which a plurality of gas flowing holes, with a hexagonal shaped cross section, are provided on a disk-shaped ceramic plate. The heating plate 10 is heated by the burner 8, and can uniformly raise the temperature of the combustion gas of which the temperature is not sufficiently raised only by the flames of the burner 8, when the combustion gas passes through the gas flowing holes on the heating plate 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a smoke deodorizing method and apparatus for an incinerator for eliminating smoke and odor of combustion gas generated in an incinerator for incinerating waste.

[0002]

2. Description of the Related Art Generally, some incinerators have only a combustion chamber for injecting waste to incinerate it, and others have both a secondary combustion chamber communicating with the combustion chamber. Then, in the later-described one, the combustion gas of the waste incinerated in the combustion chamber is sent to the sub-combustion chamber and further heated and burned by a heavy oil burner or the like so as to deodorize the combustion gas.

[0003]

However, when incinerating rubber products or polymer resins, the conventional method that relies only on the combustion of a burner or the like uses the combustion gas generated from the incinerated matter as a burner gas. The flame cannot be evenly contacted. Further, there is a problem that it takes a long time to raise the temperature in the furnace, and it is difficult to completely eliminate smoke and odor of the combustion gas. The present invention has been made in view of the above problems, and an object thereof is to provide a smoke deodorizing method and apparatus for an incinerator capable of completely eliminating smoke and odor of combustion gas generated from waste in a short time. To do.

[0004]

Therefore, in the present invention, a method for deodorizing smoke in an incinerator is provided, in which a gas for burning combustion gas generated from the combustion chamber is provided in communication with the combustion chamber. In an incinerator including a combustion chamber, the combustion gas is retained, and a heating body through which the combustion gas can flow is provided in the gas combustion chamber to raise the temperature of the combustion gas.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a conceptual diagram showing a method for deodorizing smoke in an incinerator according to the present invention, FIG. 2 is a perspective view of a heating plate according to the present invention, and FIG. 3 is a perspective view showing another embodiment of the heating plate according to the present invention. It is a figure.

As shown in FIG. 1, the inside of the incinerator body 1 is
Primary combustion chamber 2 and combustion chamber 2 that incinerate waste in order from the bottom
The secondary combustion chamber 3 and the tertiary combustion chamber 4, which are gas combustion chambers for burning the combustion gas generated from the
Gas retention chambers 5 and 6 are provided so that the respective combustion chambers communicate with each other. Burners 7, 8 and 9 are provided horizontally in the respective combustion chambers toward the inside thereof so as to emit a flame to the combustion chambers.

A heating plate 10 is provided in the secondary combustion chamber 3 and the tertiary combustion chamber 4 so as to face the burners 8 and 9.
Here, as shown in FIG. 2, the heating plate 10 is formed in a so-called honeycomb structure mesh in which a plurality of gas flow holes 10a having a hexagonal cross section are formed in a disk-shaped ceramic.

Next, the operation of this embodiment will be described. When the waste is incinerated by the burner 7 in the primary combustion chamber 2,
Combustion gas containing smoke and odor is generated. The combustion gas rises in the incinerator body 1 and first accumulates in the gas retention chamber 5 to fill it. Next, this combustion gas enters the secondary combustion chamber 3 and is heated and burned by the burner 8. Here, the heating plate 10 is heated by the burner 8 and is in a burning state, and when the combustion gas flows through the gas flow holes 10a of the heating plate 10, the combustion gas which cannot be heated up only by the flame of the burner 8 is heated. Can be uniformly heated. After that, the same operation is repeated in the tertiary combustion chamber 4, and the smoke and odor of the combustion gas are exhausted from the chimney 11 in a completely eliminated state. In addition, although the material of the heating plate is ceramic in the above-mentioned embodiment, the material is not limited to this, and castable cement or metal may be used, and one having heat resistance of about fire brick is preferable. Further, although the heating plate is formed in a net-like structure having a honeycomb structure, the present invention is not limited to this, and the cross-sectional shape of the flow holes 10a may be circular or quadrangular. However, the contact area between the combustion gas and the heating plate is wide. In consideration of the flow resistance and the flow resistance, the polygon such as the above-mentioned hexagon is preferable. Further, although the method of heating the heating plate by the flame of the burner is adopted for the heating body, the method is not limited to this, and the heating body itself may radiate heat by energization or the like. Furthermore, although the heating element is formed in a disk shape in the above embodiment, the heating element is not limited to this and may be a rectangular disk shape as shown in FIG. 3, which is adapted to the cross sectional shape of the gas combustion chamber. I wish I had it.

[0009]

As described above, according to the present invention, the method for deodorizing smoke in an incinerator is provided with a gas combustion chamber for communicating with a combustion chamber and combusting a combustion gas generated from the combustion chamber. In the incinerator consisting of, since the combustion gas is retained, a heating body through which the combustion gas can flow is provided in the gas combustion chamber to raise the temperature of the combustion gas. It has an excellent effect that it can completely eliminate the smoke and smell.
