In other words, by making the temperatures of the first to third cooling chambers 11-13 to 11-15 different depending on the carbonized material, the carbonized product can be cooled appropriately.

Rear standby preparation step (S107)
When the sixteenth partition door 26-16 opens and the third cooling chamber 11-15 and the first rear preparation chamber 11-16 communicate with each other, the fifteenth moving means 12-15 and the sixteenth moving means 12-16 The container 2 is moved from the third cooling chamber 11-15 to the first rear preparation chamber 11-16. When the container 2 reaches a predetermined position in the first rear preparation chamber 11-16, the sixteenth partition door 26-16 is closed and the seventeenth partition door 26-17 is closed. 11-16 becomes blocked. In the first rear preparation chamber 11-16, nitrogen is introduced from the sixteenth introduction pipe 14-16, and at the same time, the internal decomposition gas and air (oxygen) are discharged from the sixteenth discharge pipe 15-16 to form a nitrogen atmosphere. .
When the seventeenth partition door 26-17 opens and the first rear preparation chamber 11-16 and the second rear preparation chamber 11-17 communicate with each other, the sixteenth moving means 12-16 and the seventeenth moving means 12- 17, the container 2 is moved from the first rear preparation chamber 11-16 to the second rear preparation chamber 11-17. When the container 2 reaches a predetermined position in the second rear preparation chamber 11-17, the seventeenth partition door 26-17 is closed and the eighteenth partition door 26-18 is closed. 11-17 becomes blocked. In the second rear preparation chamber 11-17, nitrogen is introduced from the seventeenth introduction pipe 14-17, and at the same time, the internal decomposition gas and air are discharged from the seventeenth discharge pipe 15-17 to form a nitrogen atmosphere.
The cracked gas and air from the sixteenth exhaust pipe 15-16 and the seventeenth exhaust pipe 15-17 are deodorized and smoke eliminated by the second deodorant and smoke eliminating device 17-2, purified and released into the atmosphere. .
The rear standby preparation unit 9 includes a first rear preparation chamber 11-16 and a second rear preparation chamber 11-17, so that internal odors and gases that flow backward when the front chambers are opened to the outside are externally provided. In addition, the temperature control of the composition-separated carbonization system 1 can be made strict, and heat loss can be suppressed to contribute to energy saving.

Container unloading process (S108)
When the eighteenth partition door 26-18 is opened and the carry-out port 29 on the other end surface of the second rear preparation chamber 11-17 is opened, the container 2 containing the carbonized material is moved by the seventeenth moving means 12-17. It is discharged from the second rear preparation chamber 11-17 to the outside, and is then carried out by the container carry-out unit 10.

Thereafter, the carbonized material in the container unloading unit 10 that has been unloaded has a different shape and size depending on the type, and is separately collected as metals or carbon material components. In this case, at the same time, earth and sand, iron, non-ferrous metal, glass material, or rare metal can be easily collected separately for each composition.
The separately collected materials are reused as industrial carbon materials.

As a result, in this embodiment, the generation of harmful substances such as carbon dioxide and unnecessary residues (Schlitter dust) is suppressed, and oxidation combustion (thermal decomposition by high-temperature oxidation: oxidation reaction, reduction reaction) does not occur. In this way, the separation of the composition of the raw materials can be improved to increase the efficiency of the carbonization treatment, and there is no possibility that air pollution or water pollution will occur.
Further, as shown in FIG. 3, at least the decomposition chambers 11-8 to 11-12 are constituted by a layered heat insulating structure 30 in which a plurality of boards 31-1 to 31-3 and 32-1 to 32-3 are overlapped. Is formed. As a result, the heat insulation effect of the decomposition chambers 11-8 to 11-12 is enhanced, and when the function of the inner wall surface 30A of the layered heat insulation structure 30 is deteriorated, only the inner hard board 31-1 is replaced. Good maintenance and inspection can be facilitated and inexpensive.
Further, as shown in FIG. 3, a plurality of protrusions 33 are formed on the inner wall surface 30 </ b> A of the layered heat insulating structure 30 so as to be an uneven surface. As a result, the cracked gas impinges on the inner wall surface 30A on which the protrusions 33 are formed, so that the flow of the cracked gas is not linear and complicated, and the stirring of the cracked gas is promoted so that the cracked gas does not stay. The raw material can be heated evenly, and the time for the carbonization treatment can be shortened.
Also, as shown in FIG. 3, by driving the stirring fan 34, the cracked gas flows randomly and efficiently agitates in cooperation with the inner wall surface 30A on which the protrusions 30 are formed. The difference can be eliminated, the raw material can be heated uniformly, and the time for carbonization can be shortened.
Furthermore, since the carbonized product cooling unit 8 indirectly cools the carbonized product to a temperature at which combustion and evaporation do not occur, the temperature of the carbonized product can be appropriately lowered and the generation of harmful substances can be suppressed.

FIG. 7 shows a first modification of the present invention.
As shown in FIG. 7, for example, when the container 2 reaches the fifth decomposition chamber 11-12 in the composition separation / decomposition unit 7, the container 2 is moved to the front first to fourth decomposition chambers 11-8 to 11- Return movement means 61 for returning any of the 11 decomposition chambers was provided. In this case, the return moving means 61 includes, for example, devices such as a roller conveyor and a direction changing machine.
As a result, when the carbonization of the raw material of the container 2 is insufficient even when it reaches the fifth decomposition chamber 11-12, the container 2 is used as the front chamber, and the first to fourth decomposition chambers 11-8 to 11-1 are used. By returning to any one of the chambers and further carbonizing, the carbonization treatment can be performed reliably.
The return moving means 61 is not limited to the composition separation / decomposition unit 7, but also in the front standby preparation unit 4, the water evaporation unit 5, the polymer compound removal unit 6, the carbonide cooling unit 8, and the rear standby preparation unit 9. The provided structure is applicable.

FIG. 8 shows a second modification of the present invention.
As shown in FIG. 8, the composition-separated carbonization system 1 is configured to be capable of self-running. In the composition separation type carbonization system 1, a front standby preparation unit, a water evaporation unit, a polymer compound removal unit, a composition separation decomposition unit, a carbonized product cooling unit, and a rear standby preparation unit are integrally assembled in a housing 62. The plurality of wheels 63 as moving means at the bottom of the housing 62 can be moved to a place where the raw material G exists. The housing 62 is provided with a raw material charging hopper 64 for charging the raw material and a take-out portion 65 for taking out the carbonized material. The raw material G is charged into the raw material charging hopper 64 by a device 66 such as a heavy machine.
As a result, the composition separation type carbonization system 1 is moved to the site where the raw material G exists, and the carbonization treatment becomes possible on the site, so there is no need to transport the raw material G to another building, etc. The carbonization system 1 can be easily used.
