Description

図1は、本発明の実施形態に係る廃棄物分離回収システムの全体構成を示す図、図2は廃棄物分離回収装置の詳細を示す図である。本実施形態に係る棄物分離回収システム1は、熱分解炉2、燃焼装置3、冷却・混合槽4、脱水・洗浄装置5、水処理装置6、熱分解残渣洗浄装置7、噴射装置8及び排ガス処理装置9を備える。 FIG. 1 is a diagram showing an overall configuration of a waste separation and recovery system according to an embodiment of the present invention, and FIG. 2 is a diagram showing details of a waste separation and recovery device. Waste separation and recovery system 1 according to this embodiment, the pyrolysis furnace 2, the combustion device 3, a cooling-mixing tank 4, dehydration and cleaning apparatus 5, water treatment system 6, the pyrolysis residue cleaning apparatus 7, injector 8 And an exhaust gas treatment device 9.

大略前述のように構成された廃棄物分離回収システムでは、一般ゴミである廃棄物Xは、廃棄物投入器(図示せず)により熱分解炉2に供給される。熱分解炉2は、投入された廃棄物Xを、燃焼装置3から排出されて前記加熱ジャケットに供給される燃焼排ガスcによって間接的に加熱し、低酸素状態で熱分解する(熱分解プロセス)。廃棄物Xに含まれた可燃性廃棄物は、その熱分解によって、熱分解ガスaと熱分解残渣、すなわち炭化物bとに分離される。廃棄物Xには不燃物(鉄,アルミニウム等の金属及び瓦礫等)が含まれているが、この不燃物は熱分解しない。熱分解ガスaは、配管30を通って燃焼装置3に供給され、燃焼装置3で燃焼する。発生した燃焼(排)ガスcは、配管31により熱分解炉2の加熱ジャケット内に供給され、前述のように熱分解炉2内の廃棄物Xの加熱に用いられる。加熱ジャケットから排出された燃焼(排)ガスcは、配管32により排ガス処理装置9に供給され、所定の排ガス処理が施され、外部環境に放出してもよい状態まで浄化された後、配管33を経て煙突5から外部環境に排出される。 In the waste separation and recovery system generally configured as described above, waste X, which is general waste, is supplied to the pyrolysis furnace 2 by a waste input device (not shown). The pyrolysis furnace 2 indirectly heats the input waste X with the combustion exhaust gas c discharged from the combustion device 3 and supplied to the heating jacket, and thermally decomposes it in a low oxygen state (pyrolysis process). . The combustible waste contained in the waste X is separated into pyrolysis gas a and pyrolysis residue, that is, carbide b, by thermal decomposition. The waste X contains incombustibles (metals such as iron and aluminum and rubble), but the incombustibles are not thermally decomposed. The pyrolysis gas a is supplied to the combustion device 3 through the pipe 30 and burns in the combustion device 3. The generated combustion (exhaust) gas c is supplied into the heating jacket of the pyrolysis furnace 2 through the pipe 31 and used for heating the waste X in the pyrolysis furnace 2 as described above. Combustion (exhaust) gas c discharged from the heating jacket, is fed to an exhaust gas processing device 9 by a pipe 32, a predetermined exhaust gas treatment is performed, after being purified to good condition be released to the outside environment, piping 33 is discharged from the chimney 5 to the outside environment.

熱分解2で炭化物bとなった廃棄物Xは、出口ノズル40から水が充填された冷却水槽4−1内に供給される。炭化物bは冷却水槽4−1内で強制的に撹拌され、水と混合される。この水との混合により急冷された炭化物bは、投入された分の約30%が水に浮遊し、残りの約70%が沈降する。これは約500℃の炭化物bを冷却水槽4−7内の水中に投入したときの実験から確認されている。 Waste X that has become carbide b in the pyrolysis furnace 2 is supplied from the outlet nozzle 40 into the cooling water tank 4-1 filled with water. The carbide b is forcibly stirred in the cooling water tank 4-1 and mixed with water. About 30% of the charged carbide b rapidly cooled by mixing with water floats in the water, and the remaining about 70% sinks. This is confirmed from an experiment when the carbide b of about 500 ° C. is put into the water in the cooling water tank 4-7.
