May be cooled to a temperature of about 100 ° C. to 300 ° C., for example, to prevent heat damage to the connected equipment such as the pressure feeding means 42. Since the inert gas (oxygen-free gas) discharged from the discharge port 40 is burned at a high temperature as described above, it is completely detoxified and therefore does not adversely affect the environment. .

The cooling means 5 is connected to the auxiliary discharge chamber 9a which is in communication with the discharge chamber 9 and cools the carbide b treated in the rotary furnace body 1 after taking it out. Carbide b is sent to the cooling furnace body 145 such as the kiln of FIG. Further, the delivery member 46 connected to the bottom of the auxiliary discharge chamber 9a is connected to the supply port 47 provided on one side of the cooling furnace body 145, and the carbide b that has been cooled to a predetermined temperature after the treatment is The cooling furnace body 145 is discharged from an outlet 48 provided on the other side.

In this state, the rotary furnace body 1 is rotated in one direction at a constant speed by the rotating means 7, and the raw material charging means 11 facing the charging chamber 8 of the rotary furnace body 1 makes it to a predetermined grain size, for example. The crushed raw material b1 is supplied into the rotary furnace body 1 by a constant amount. At this time, in the rotary furnace body 1, for example, the raw material occupancy rate in the rotary furnace body 1 is controlled to 20% or less. Further, the raw material b1 is fed to the bottom of the charging chamber 8, and the raw material b1 is agitated by the feeding blades 16 provided in the charging chamber 8 and is leveled into a layer having a predetermined thickness while being directed to the downstream side. That is, due to the inclination of the rotary furnace body 1 and its rotation, the rotary furnace body 1 is transferred to the processing chamber 10 while sliding in the rotary furnace body 1. At this time, the gas deactivated (deoxidized) from the second combustion chamber 4 is sent to the sub-charging chamber 8a after the temperature thereof is adjusted to a predetermined temperature by the heat exchangers 35a and 35b. The charging chamber 8 communicating with the auxiliary charging chamber 8a is preheated to, for example, 100 ° C. to 200 ° C., and along with this, the raw material b1 is also preheated and warmed.

And is delivered to the inside of the first combustion chamber 17 through its outlet 28 that is exposed to the outside of the processing chamber 10, and the dry distillation combustion gas is burned by the first combustion chamber 17 at a temperature of 400 ° C to 500 ° C. It The amount of heat generated by the combustion of the dry distillation gas saves the heating of the combustion means 25.

The pressure in the processing chamber 10 becomes low. This allows
Even if the pressure inside the processing chamber 10 becomes negative, the inert gas (oxygen-free gas) flows into the auxiliary charging chamber 8a and the auxiliary discharging chamber 9a, and the charging partition member 18 of the charging chamber 8 and the discharging chamber 9 are discharged. Partition member 1
Since the inside of the processing chamber 10 is partitioned by the reference numeral 9, there is no inflow of air from the outside, there is no outflow of dry distillation gas in the processing chamber 10, and the inside of the processing chamber 10 is maintained in a substantially sealed state in an oxygen-free atmosphere. Therefore, the raw material b1 is carbonized without being burned by oxygen.

The gas combusted in the first combustion chamber 17 is sent to the second combustion chamber 4, and at a higher temperature, for example, 800 ° C. to 10 ° C.
It is burned at a temperature of 00 ° C, further decomposed by heat to be rendered harmless, and deodorized and smoked. In this way, the more inert oxygen-free gas in the second combustion chamber 4 is cooled to a predetermined level via the heat exchangers 35a and 35b, and then supplied to the sub charging chamber 8a and charged by the raw material charging means 11. The raw material b1 to be produced is preheated, and oxygen-free gas is supplied to the sub-charging chamber 8a to prevent oxygen from entering from the outside such as the raw material feeding means 11. Further, an oxygen-free gas is also supplied to the discharge chamber 9 to cool the carbide b, and the inside of the discharge chamber 9 is kept in an oxygen-free atmosphere to prevent ashing due to burning of the carbide b. Further, a part of the oxygen-free gas that has been deactivated as described above is discharged from the discharge port 40 to the atmosphere or the like via the pressure feeding means 42.

Carbide b carbonized in the processing chamber 10
Along with the rotation of the rotary furnace body 1, the discharge partition member 19 transfers a fixed amount to the discharge chamber 9 and then to the auxiliary discharge chamber 9a communicating with the discharge chamber 9 so that the auxiliary discharge chamber 9a It is conveyed to the cooling means 5 via the delivery member 46 connected to the bottom. By this cooling means 5, the carbide b from the rotary furnace body 1 is cooled to room temperature to prevent ignition.

The carbide producing apparatus A of this embodiment has a water content of 9
Not only the carbonization treatment of 0% or more of the raw material b1 but also most of the currently discharged organic waste can be carbonized. A desired carbonization process is achieved by appropriately adjusting the input amount of the raw material b1 by 11 and the rotation speed (rotation speed) of the rotary furnace body 1 and the temperature in the processing chamber 10, that is, the temperature in the first combustion chamber 17. It The produced carbide b can also be processed into semi-carbonization. Examples of the present invention, high water content raw material, for example, used in beverages,
