Put (8) in bucket (7) and store in waste storage (3). Then, the superheated steam generated in the combustion furnace (11) is guided to the heat source conduit (9) in the carbonization furnace (1), and the combustion furnace (11)
The exhaust gas generated inside is supplied between the furnace wall (2) of the carbonization furnace (1) and the waste storage chamber (3). This makes the waste storage room
(3) and the coil (9) are heated. The exhaust gas is then
Emitted from the exit chimney (16). When the temperature in the waste storage chamber (3) approaches the upper limit, cooling water is injected from the water spray device (19) into the exhaust gas conduit (15). This enables the carbonization furnace
(1) The temperature inside can be easily controlled. At this time, since the temperature in the combustion furnace (11) does not drop, incomplete combustion in the combustion furnace (11) does not occur. Under such heating conditions, the steam in the heat source conduit (9) is spray-supplied from the heat source blowing nozzle (10) to the waste (8) in the bucket (7), and the waste (8) is carbonized. As a result, the rubber that constitutes the waste (8) is thermally decomposed, and the organic gas generated during the thermal decomposition of the rubber is completely combusted in the combustion furnace (11). Valuable metals that make up the waste (8) remain in the bucket (7) and are separated from the waste (8). The valuable metal thus obtained can be reused in products as a metal material that is free from oxidation and structural change after the residual carbon content is partially removed.

必要がなくなり、熱効率が良いものとなる。The amount of valuable metal contained in the waste (8) is much smaller than that of rubber, and the bucket (7) will not be filled with metal after several treatments. Therefore, it is not necessary to collect valuable metal every time the above treatment is performed, and the waste (8) is continuously fed to the upper and lower dampers (5).
Can be supplied from. At this time, the lower damper
With the (5) closed, throw in the waste (8) from the upper damper (5), close the upper damper (5), and if necessary, shut off the outside air blocking gas between the upper and lower dampers (5). Inert gas or superheated steam is blown from the blowing device (18), and the waste (8) is dropped from the lower damper (5) into the waste storage chamber (3). This prevents outside air from flowing into the carbonization furnace (1) and heat from the carbonization furnace (1), preventing both an increase in oxygen concentration in the furnace (1) and a decrease in temperature inside the furnace (1). It Therefore, it is not necessary to lower the temperature inside the equipment for each treatment, as compared to the batch-type treatment in which valuable metal is taken out each time the waste (8) treatment is finished and new waste rubber metal composite material is input. , Thermal efficiency will be good.
