Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste carbonization apparatus for pyrolyzing general waste including livestock manure, agricultural waste, food waste, etc. in an oxygen-free state and carbonizing the waste.

[0002]

2. Description of the Related Art In recent years, general wastes including livestock manure, crop waste, garbage and the like, which are high in water content, discharged from livestock farmers, upland farmers and general households have been incinerated. Emits, CO ₂ , SOx, NO
It has become a problem to pollute the natural environment by generating oxygen compounds such as x and harmful gases such as dioxin. Particularly, when dioxin is generated and air, water, soil, etc. are polluted, cancers on the human body may occur. It has been pointed out that the occurrence of reproductive disorders and reproductive disorders may occur, which is a major problem on the global environment. Therefore, waste is thermally decomposed in a closed treatment path without intervening oxygen, and the organic gas and odor generated by this pyrolysis are removed by burning to generate almost noxious gases such as dioxin, oxidized compounds and odors. Waste carbonization equipment for carbonizing without causing carbonization has been developed.

[0003]

However, in the waste carbonization apparatus described in the above-mentioned prior art, general waste mainly containing high-moisture livestock manure, agricultural waste, garbage, and the like is reduced to dioxin and the like. Although carbonization can be performed with almost no harmful gas or odorous gas, it takes a long time to complete pyrolysis because it is a highly water-containing waste, which increases the energy cost associated with pyrolysis. In order to realize carbonization processing of waste without generating harmful gas or odorous gas in this apparatus, there is a problem that various costs increase due to the complicated structure of the apparatus.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art. It is an object of the present invention to provide a simple apparatus and a high-content general waste in a short time. It is an object of the present invention to provide a waste carbonization apparatus which can perform carbonization without generating harmful gas such as dioxin or odorous gas, and is excellent in economic efficiency.

[0005]

The inventor of the present invention has conducted various studies on methods for overcoming the problems of the conventional waste carbonization apparatus, and as a result, the waste is stored in an airtight container in an oxygen-free state. In the waste carbonization equipment where the organic gas and odor generated by thermal decomposition are burned without intervening oxygen, the heating gas discharge port of the deodorizer can heat the heating gas chamber evenly. A heat absorbing plate is formed on the outer surface of the side wall of the carbonization chamber, where the heating gas to be discharged is uniformly heated around the entire side surface. Heat transfer plates are provided side by side in a horizontal direction at equal intervals to project the heat evenly, and a combustion chamber for heating the bottom surface is provided below the carbonization chamber, and exhaust gas is provided between the exhaust pipes. Moth And they accomplished the present invention found that can achieve the object by a cooled by ambient air steam separator formed to be gas-water separator is provided.
