Description

[Detailed description of the invention] This invention is based on the exhaust duct 2 connected to the waste tire combustion furnace 1, which is connected to the cyclone and bag filter dust collector 3.
A conveyor 5 is connected to the dust collectors 3 and 4 to carry out the exhaust dust discharged from the dust collectors 3 and 4, and the terminal end of the conveyor 5 is connected to the combustion furnace 1 from below the carbonized dust outlet 6.
The present invention relates to a combustion furnace carbonized dust processing device in which a carbonized dust removal box 25 is disposed in a protruding upper part of a carbonized dust reservoir 7 recessed outside the discharge port 6 and disposed in the carbonized dust reservoir 7. The combustion furnace 1 has a rotor 9 inside the cylinder 8.
A cylindrical fence is provided on the outer periphery of the cylinder 8, and the cylindrical fence is concentric with the cylinder 8. The cylindrical fence is made up of a large number of upright short rods 10 and connecting horizontal rods 11, and the material input port 12 provided in the cylinder 8 can be freely opened and closed. Opens inside the cylindrical fence.
A large number of air jet holes 13 are made to protrude into the gap t between the cylinder 8 and the cylindrical fence. The air jet holes 13 are provided in upper and lower annular air blowing ducts 14 and 15, and the annular air blowing ducts 14 and 15 are connected to a blower 16 through a duct 17. The combustion gas duct 18 is connected to the center of the sealed ceiling 19 at the upper end of the cylinder 8, which is connected to the boiler 20, and is connected to the exhaust duct 2.
may be connected to the combustion furnace 1 via the same boiler 20. In the figure, 21 and 22 indicate a carbonized dust guide cylinder, 23 a carbonized dust hopper, 24 a damper, and 2
6 is a tire, 27 is a tire supply conveyor, and 28 is a chimney.

Therefore, a waste automobile tire 26 is placed on the upper surface of the cylindrical fence inner rotor 9, ignited, and the blower 16 is operated to blow air from the jet hole 13 into the cylinder 8.
When the air is blown into the inside of the rotor 9, the air ejected from the nozzle 13 swirls and burns the waste tire 26 on the rotor 9. Then, carbonized dust 29 is dropped and deposited on the lower part of the roaster 9. The combustion gas on the roistle 9 rises and is supplied to the boiler 20 from the combustion gas duct 18. The gas discharged from the boiler 20 enters the cyclone dust collector 3 from the duct 2 by the blower 28, and the fallen carbonized dust flows from the induction tube 21 to the conveyor 5.
A part of the scattered dust is sent to the bag filter dust collector 4, enters through the entrance of the bag, enters a number of upright bags, and carbonized dust is collected in the bags, falls from the guide tube 22, and is transferred to the conveyor. The clean gas that has entered the chamber 5 and passed through the bag is discharged to the atmosphere from a chimney 28 by a blower. The carbonized dust that has entered the conveyor 5 is transported by the conveyor 5 from below the discharge port 6 into the carbonized dust transport box 25 placed in the carbonized dust reservoir 7, and the high-temperature carbonized dust below the roaster 9 is also transferred to the conveyor 5. 5 and is housed in the same box 25.
The full carrying out box 25 thus constructed is the empty carrying out box 25.
The fully loaded carry-out box 25 is left at the carry-out position. At the abandoned position, high-temperature carbonized dust 2 in the same carry-out box 25
9: Natural combustion without flame and time elapsed (about 3 days)
Since this becomes white dust, the operation of carrying it out and disposing of it using the same box 25 and making it an empty box is repeated.

In conventional combustion devices, it is difficult to convert black carbonized dust into white dust when burning tires, and it is also difficult to dispose of black carbonized dust. Furthermore, since the black carbonized dust discharged from the cyclone and bag filter dust collector and the black carbonized dust from the combustion furnace are mixed in a cooled state, it is difficult to turn them into white dust (Utility Model Publication No. 55-7703). This black carbonized dust must be sealed with water (Utility Model Publication No. 54-43172), and even if it is sealed with water, it is likely to scatter during subsequent drying and pollute the atmosphere.

This proposal was made in view of the above defects, and
Since the present invention is configured as described above, the black carbonized dust generated by the combustion of the tire material 26 is carbonized in a high temperature state without being cooled from the waste tire combustion furnace 1 and the cyclone and bag filter dust collectors 3 and 4. Not only can the dust be stored in the dust removal box 25, taken out, left at the removal position, and spontaneously combusted at the above-mentioned high temperature to turn it into white dust, but also it can be removed from the atmosphere of black soot and black scattered dust. There is a benefit in sufficiently preventing the release of
