  As described above, according to the carbonization treatment apparatus 1 in which the preliminary furnace 3 is communicatively connected to the carbonization furnace 2 and the steam can be jetted to the preliminary furnace 3, the preliminary furnace 3 can be By temporarily injecting steam and taking time to complete the carbonization treatment in the carbonization furnace 2 to naturally lower the temperature in the preliminary furnace 3, the steam condenses and oxygen in the preliminary furnace 3 Concentration also decreases. Then, by sliding the open / close door 4 upward, the temperature of the carbonization furnace 2 is also lowered, and since the oxygen concentration in the preliminary furnace 3 is lowered, explosion and disposal in the carbonization furnace 2 are caused. It is possible to prevent the ignition of the residue of substance X.

  The procedure of the carbonization process in the carbonization treatment apparatus 1 configured as described above will be described below.

If the open / close door 4 is opened in this state and the carbonization furnace 2 and the preliminary furnace 3 are communicated, the temperature of the carbonization furnace 2 also decreases, and since the oxygen concentration is also low, explosion occurs in the carbonization furnace 2 even immediately after carbonization treatment And waste X residue can be prevented from igniting.

  Finally, the door 26 is slid upward and opened, and the carbonized waste X in the carbonization furnace 2, ie, the carbonized product, is taken out from the loading / unloading port 25.

  The series of carbonizing furnaces 2 is partitioned into sections by the open / close door 4 and, in this embodiment, is divided into seven sections of section A to section G. The respective compartments can communicate the inside of the carbonizing furnace 2 by opening and closing the open / close door 4 provided between both ends of the series of carbonizing furnaces 2 and between the respective compartments, or can make the respective compartments be independent spaces It has become.

  Among the divisions A to G divided in this way, in the present embodiment, the first division A receives the water vapor sent from the boiler 22 of the waste X carried into the carbonization furnace 2 from the water vapor injection holes 31 It is a section for heating by injecting and volume reduction of the waste X. Further, the intermediate sections B to E are provided with superheated steam generation means 23 for each section, and the predetermined different temperatures according to the vaporization temperature difference of the oil contained in the waste X, for example, 150 in the section A Water vapor at a temperature of ° C., superheated steam at a temperature of 300 ° C. in section B, 450 ° C. in section C, and 600 ° C. in section D is supplied from the steam injection holes 31. Section E, section F and the last section G are sections for gently cooling the carbonized product before taking it out of the carbonizing furnace 2, and the section E is supplied with superheated steam at about 150 ° C. Water vapor is supplied from the boiler 22 to the section F, and the section G is provided with a blower 6 for cooling. Depending on the type of waste X, the section E may be subjected to superheated steam treatment at a high temperature of 600 ° C. or higher such as 1300 ° C. to cool the carbonized product in the sections F and G.

  The spare compartment 3 temporarily injects steam from the steam injection holes 31 and removes the air in the spare compartment 3 to increase the ratio of the steam in the spare compartment 3 so that the water vapor passes over time. The oxygen concentration in the reserve compartment 3 can be reduced as the temperature in the reserve compartment 3 naturally drops to become water droplets.

  The open / close door 4 is provided between each section of the carbonization furnace 2 and the spare section, and is made to communicate with each section by sliding upward, while when performing carbonization treatment in each section of the carbonization furnace 2 , It is installed to seal the inside of these compartments by sliding downward. In the present embodiment, the open / close door 4 is configured to move up and down in the vertical direction, but it is an aspect of any open / close door 4 as long as the sections can be communicated and sealed. It is also good.

  The transfer means 5 is a transfer conveyer, places the waste X, and transfers the inside of the carbonization furnace 2 from the reserve section 3 in the order of the sections A to G. In addition, the said waste X is mounted in the conveyance means 5 in the state accommodated in the container 7. FIG. Further, the transport means 5 is activated each time the waste X performs the treatment in each section, for example, when a certain waste X is transported from the section A to the section B, the progress of the superheated steam treatment performed in the section B After waiting for time, the waste X is transported to section C. In this way, waste X is treated in each of the compartments A to G in sequence. In addition, a plurality of motors are installed in each section along the transport path, and the transport unit 3 transports the waste X based on an instruction from the operation control unit.

  The carbonization treatment apparatus 1 configured in this way has, for example, the treatment temperature of the first section A at 150 ° C. and the treatment temperature of the section B at 300 ° C. as described above, and after the carbonization treatment in each section When the open / close door 4 between the sections B is slid upward and opened, the temperature in the section A also becomes 200 ° C. or more due to the high-temperature section B. In such a state, when the open / close door 4 between the reserve compartment 3 and the first compartment A is opened, as described above, in the reserve compartment 3, the oxygen concentration is lowered along with the condensation of water vapor due to the temperature decrease. As a result, no explosion occurs in the first section A, and ignition of waste X after treatment in section A can also be prevented.

  Next, the procedure of the carbonization process in the carbonization treatment apparatus 1 of the second embodiment will be described below.

  First, the container 7 containing the waste X is placed on the transfer means 5 outside the reserve section 3 (left side in the drawing), and the transfer means 5 is operated to transfer to the inside of the reserve section 3. Then, the second container 7 containing the waste X is placed on the transfer means 5 outside the reserve section 3, and the transfer means 5 is operated to transfer the waste X to the inside of the reserve section 3. Along with this, the container 7 placed first is transported to the first section A.

  Next, the open / close door 4 on the outer side of the reserve section 3 and the open / close door 4 between the sections are slid downward to make these sections sealed, and then in the first section A, the predetermined temperature and the predetermined At time intervals, waste X in container 7 initially placed at a temperature of, for example, 150 ° C. for one and a half hours is carbonized.

  Here, when the carbonization process is started, water vapor is temporarily injected from the water vapor injection holes 31 of the reserve compartment 3 so that air in the reserve compartment 3 is eliminated, and the reserve compartment 3 is filled with water vapor. Make it As described above, in the preliminary section 3 filled with water vapor, while the carbonization treatment is performed in the first section A, the temperature of the inside decreases and the water vapor condenses. Along with that, the oxygen concentration in the reserve section 3 also decreases.

  Then, by the time the carbonization treatment in the first section A is completed, the temperature in the preliminary section 3 is lowered to about normal temperature to about 60 ° C., and the oxygen concentration in the preliminary section 3 is low. It has become. In this state, when the open / close door 4 is opened and the first compartment A and the reserve compartment 3 are communicated, the temperature of the first compartment A also decreases, and the oxygen concentration is also low. A can prevent explosion and ignition of waste X residue.

  In addition, while carbonizing the waste X of the container 7 placed first in the first section A, the third container 7 is placed on the transport means 5 outside the reserve section 3. As described above, when the carbonization process is completed in the first compartment A, the open / close door A is opened, the third container 7 into the reserve compartment 3, the second container 7 into the first compartment A, the first container 7 Each is transported to section B. Then, for example, superheated steam treatment at 300 ° C. in compartment B and steam treatment at 150 ° C. in compartment A for 1 hour and 30 minutes, and when the carbonization treatment is started, steam is temporarily injected in reserve compartment 3 And, as noted above, reduce the temperature and oxygen concentration during carbonization of compartments A and B.

  Here, when transporting the third container 7 to the reserve section 3, even if the second container 7 is transported to the first section A and the first container 7 to the section B and carbonization processing is started, The third container 7 is caused to stand by for a predetermined time, for example, about 20 to 30 minutes, by the transport means 5 outside the reserve compartment 3, and the temperature of the third compartment 7 is sprayed by After cooling, the open / close door 4 on the outside (left side in the drawing) of the reserve section 3 can be opened and transported into the reserve section 3. This is because, when the open / close door 4 between the reserve section 3 and the first section A is opened after the previous carbonization treatment, the temperature of the first section A decreases while the temperature of the reserve section 3 becomes 100 ° C. or more When it rises, if the open / close door 4 outside the reserve section 3 is opened, oxygen flows in from the outside at a stretch, and there is a possibility that explosion or ignition to the waste X may occur in the reserve section 3. Thereafter, in the reserve section 3, after the temporary steam injection for the remaining about 1 hour to 1 hour 10 minutes, as described above, the temperature of the reserve section 3 during the carbonization treatment of the sections A and B and Reduce the oxygen concentration. Thereby, the door 3 outside the reserve section 3 can be opened more safely, and immediately after the carbonization treatment for 1 hour 30 minutes in the section A, the door between the reserve section 3 and the section A You can also open 4.

  As described above, in the carbonization treatment apparatus 1, the containers 7 in which the wastes X are stored are sequentially transported to each section in a row, and each of the sections A to G of the carbonizing furnace 2 has a predetermined time. The treatment is performed at intervals, and in the reserve section 3, the oxygen concentration is reduced by condensation of the water vapor at each time interval. With such a configuration, even if the open / close door 4 is opened for each carbonization treatment in the first section A applied at the predetermined time interval, oxygen does not flow into the first section A at a stretch, and the first section Since the temperature in the compartment A decreases, it is possible to prevent the explosion or ignition in the first compartment A in the processing at predetermined time intervals.

  In addition, since the open / close door 4 between the reserve section 3 and the first section A can be opened immediately after carbonization, the container 7 containing waste X is transported from the first section A to the next section B. Because it is not necessary to wait for it and carbonization can be performed smoothly, productivity of carbonized material can be improved.

As described above, according to the carbonization treatment apparatus and the carbonization treatment method according to the present invention, explosion and the like in the carbonization furnace 2 or the first section A can be prevented, and the open / close door 4 is opened immediately after the carbonization treatment. As a result, the waste X can be carbonized safely and smoothly, and productivity can be improved.
