(57) [Summary] [PROBLEMS] In a technology for thermal decomposition and treatment of waste, The separation of pyrolysis residues is surely and simplified, and the waste treatment system is thereby simplified. SOLUTION: A fluidized bed separation apparatus 1 is provided with inclined porous plates 3 and wind boxes 4a to 4c partitioned by partition walls 8. Are provided with a large number of air ejection holes 6, and each of the ejection holes 6 is provided with an eave 7. The pyrolysis residue is supplied from supply port 2, Fluidized by the air jetted from the many air jet holes 6 and the fluid medium, the combustible components attached to the fine particles and incombustibles are also separated and taken out from the outlet 9. The relatively heavy residue is discharged from the outlet 10. As described above, since the powder such as the pyrolytic carbon in the pyrolysis residue is separated in advance, the separation of the pyrolysis residue can be surely and simplified, and an efficient and economical waste treatment system can be realized. In addition, early separation reduces contamination of downstream equipment. |
