It is desirable to return to the above and thermally decompose. Also, the charging chamber 4
Although not shown in the figure, the damper is formed in multiple layers and strictly sealed, so that the waste tire 2 can be put in during the operation of this device. Next, the opening 9 of the air tube 7 was formed as shown in FIGS.
3 is a view taken along the line III-III of FIG. 2, and FIG. 4 is a view taken along the line IV-IV of FIG. The openings 9 are formed in upper and lower two stages as shown in the drawing, and the fluidized bed forming portion 13 is formed in the lower stage in the openings 9a.
On the other hand, it is formed in the radial direction and in the tangential direction in the upper opening 9b. The lower opening 9a is the air amount Ao (Nm 3 / min) required for fluidization of the fluidized bed 5, and the upper opening 9b is the air amount A '(Nm 3 / min) required for gasification of waste tires. By increasing or decreasing the air amount A ', the waste tire processing amount is controlled. The thermal decomposition temperature of the fluidized bed 5 is
Within the range of 600 to 800 ° C., the fluidized bed is adjusted by adjusting the amount of air in the upper opening 9b or by increasing or decreasing the amount of replacement of the medium 11 so that it can be operated at an appropriate temperature. Control the temperature of 5. Next, the both openings 9a, 9
In the height direction, b is preferably 5 to 20 degrees, which is a downward slope with respect to the fluidized bed forming portion 13. In the figure

In addition, the pressure difference between the furnace top and each part of the fluidized bed 5 is measured, and the medium 11 is adjusted so that the pressure difference becomes constant.
It controls the input and output amount of. Further, the replacement amount of the medium 11 in the fluidized bed 5 is
About 1/2 to 3 times the volume occupied by the fluidized bed 5 is replaced.

It is agitated and pulverized by the flowing medium 11, and it is soon separated from the steel cord 15 by heat and further pulverized.
It is guided to the combustion furnace together with the generated gas. Then, the steel cord 15 moves downward in the seal layer 12 together with the medium 11 by extracting the medium 11 from the lower portion of the seal layer 12 to the outside, and is sequentially discharged together with the medium 11.

ド15が採取される。Then, the steel cord 15 and the medium 11 are separated by a separating device 16 such as a magnetic separator or grizzly, and the medium 11 is returned to the freeboard unit 1 through a return path 17. Next, a water cooling jacket 18 is provided on the outer periphery of the seal layer forming portion 14 and is cooled by water 19 in the jacket 18. Due to this cooling, the medium 11 and the steel cord 15 extracted from the lower portion of the seal layer 12 to the outside have a low temperature,
The transfer device 20 and the like that accommodates this is not burned out. Further, the seal layer forming portion 14 is formed in a substantially straight tube shape, so that the steel cord 15 which is not crushed,
It can move well downwards. Next, the opening 21 of the seal layer forming portion 14 will be described. In FIG. 5, the opening 21 is formed between the upper surface 22 of the transfer machine 20 and a gap h, and the transfer machine 20 moves forward. The inclination α is set so that the opening amount becomes larger in the direction.
In the figure, the angle is preferably α = 15 to 30 degrees. When α = 0, the steel cord 15 becomes difficult to be discharged, and when the inclination α is formed too large, the sealing property is deteriorated. The transporter 20 moves in the direction of arrow A20, whereby the medium 11 containing the steel cord 15 is taken out and separated by the separating device 16. Then, the medium 11 is returned into the freeboard unit 1 and the steel cord 15 is collected.
