DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carbonization apparatus for carbonizing garbage, wood pieces, rubber pieces, plastic pieces, combustible wastes such as disposable diapers, and organic substances such as chicken dung.

[0002]

2. Description of the Related Art A conventional typical carbonizing apparatus includes a carbonizing furnace for carbonizing a processed material. The carbonizing furnace includes a carbonizing tank for defining a processing chamber and a heating chamber for covering the processing chamber. The processing chamber is provided with an agitating means for agitating the processing object accommodated in the processing chamber. Also, combustion burner means is provided in connection with the heating chamber. In such a carbonizing apparatus, the combustion exhaust gas from the combustion burner is discharged to the outside through the heating chamber, and while the combustion exhaust gas flows through the heating chamber, the processed material in the carbonization tank is heated by the heat. It is carbonized.

[0003]

The conventional carbonizing apparatus has the following problems to be solved. For example, in the case where a carbonized process is performed by containing a processed product having a low moisture content in the processing chamber of the carbonizing apparatus, the carbonizing process of the processed product rapidly proceeds, and the temperature in the processing chamber easily rises to a predetermined processing temperature or higher. If the rise rises to an abnormally high temperature, the carbonization furnace may be damaged. In addition, when carbonization is performed using a carbonization device having a relatively small volume in the processing chamber, the carbonization of the processed material rapidly proceeds, and the temperature in the processing chamber rises to a predetermined processing temperature or higher, as described above. Even in this case, if the temperature of the processing chamber rises to an abnormally high temperature,
The carbonization furnace may be damaged.

[0004] It is an object of the present invention to provide a carbonization apparatus capable of suppressing an abnormal rise in the temperature in a processing chamber, thereby preventing damage to the carbonization apparatus.
