【０００２】
【従来の技術】
廃棄物から固形化燃料を製造する技術として、例えば、特開平７−１５０１５８号公報には、ごみを破砕、乾燥、選別した後、得られた可燃物を円盤状ダイ式成形機に投入し、円盤状ダイ式成形機で発生する摩擦熱を利用して圧縮成形するという方法及び装置が開示されている。
また、例えば、特開平９−３８６１４号公報には、ブリケットマシーンに入る前のごみを成形に適する温度に調整するために、乾燥ごみを乾燥工程からの熱風排ガスの一部を用いて予熱し、成形に適する温度になった乾燥ごみをブリケットマシーンに投入して固形化する方法が開示されている。
【０００３】
また、特開２０００−２８８５０４号公報には、可燃性の廃棄物を固形物化する固形物成形機において、あらかじめ成形に適した目標温度に対して、目標温度より高い管理上限温度と、目標温度より低い管理下限温度を設定し、成形機内部の成形温度を検知し、成形温度が管理下限温度と管理上限温度の間の範囲を逸脱したときには、この範囲に戻るよう廃棄物の投入速度を変更する固形物成形機の制御方法であって、廃棄物の原料を受入ホッパ、供給コンベアを経て、破砕機、乾燥機で前処理し、缶・ビンなど金属・ガラス類の不燃物を除去し、成形機で圧縮固形化し、冷却機で冷却し、さらに未成形物選別機で未成形品をふるい処理により除去した後、製品固形物（ＲＤＦ）を製造し、未成形品である固形化されなかった粒度の小さいものを、再び成形機に投入する方法が記載されている。

【発明の実施の形態】
以下、本発明の実施の形態について説明する。本発明は下記の実施の形態に何ら限定されるものではなく、適宜変更して実施することができるものである。
図１は本発明の実施の第１形態によるごみ固形化燃料の製造方法を実施する装置を示している。本発明の装置においては、一般廃棄物、産業廃棄物等の可燃性廃棄物を固形燃料化するが、本実施形態では、原料としてごみを用い、これを圧縮成形してごみ固形化燃料（ＲＤＦ）とする場合について説明する。
【００１８】
本実施形態におけるＲＤＦ製造設備は、ごみ受入れ装置、一次破砕機、乾燥装置、選別装置、二次破砕機（以上、図示略）、可燃物ホッパー１０、可燃物定量供給機１２、成形機１４、冷却装置１６、及び分級機１８が直列に配置されて構成されている。選別装置としては、一例として、アルミニウム等の非鉄金属を分離・除去するためのアルミ選別機、磁選機、風力選別機等の組合せが用いられる。
選別装置では、破砕・乾燥したごみから鉄・アルミニウム等、及び砂・石ガラス・セラミック系物質等の不燃物が分離される。なお、プラスチックは破砕等して細かくすることで、風力選別時にごみ側に含まれるようにすることが好ましい。
【００１９】
破砕・乾燥・選別工程からのごみ（可燃物）は可燃物ホッパー１０に投入され、可燃物定量供給機１２により成形機１４に導入され、この成形機１４で圧縮成形されてＲＤＦが製造される。なお、破砕機、乾燥装置、選別装置の配置は、適宜変更することができる。この成形機１４には冷却装置１６が接続され、この冷却装置１６には分級機１８が接続されている。
【００２０】
可燃物定量供給機１２の排出部には切出装置２０を介してごみ固形化燃料（ＲＤＦ）投入ホッパー２２が設けられ、分級機１８の細粒ごみ固形化燃料（ＲＤＦ）出口２４とごみ固形化燃料（ＲＤＦ）投入ホッパー２２及び可燃物ホッパー１０とが切換手段（例えば、切換シュート）２６を備えた搬送ライン２８を介して接続されている。３０は細粒ＲＤＦの搬送手段で、バケットエレベータ、ベルトコンベヤ、桟付コンベヤ、チェーンコンベヤ、空気搬送手段等が用いられる。粗粒ＲＤＦは搬送手段３２を備えた搬送ライン３４により製品ＲＤＦとして取り出される。３６は添加剤投入口で、腐敗防止等のための添加剤（使えば、消石灰、生石灰）が投入される。
なお、分級機１８では、細粒ＲＤＦの長さが１０mm以下程度となるようにすることが好ましい。細粒ＲＤＦの長さが短かすぎると、押出しの効果がなくなる。また、粗粒ＲＤＦの平均長さは３０mm前後とすることが好ましい。
【００２１】
上記のように構成されたＲＤＦの製造装置において、ごみを破砕・乾燥・選別した後、可燃物ホッパー１０に貯留し、ついで、可燃物定量供給機１２により成形機１４に導入し成形した後、成形されたごみ固形化燃料を空冷式等の冷却装置１６に導入して冷却し、ついで、冷却されたごみ固形化燃料を振動ふるい等の分級機１８に導入して粗粒ＲＤＦと細粒ＲＤＦとに分級し、粗粒ＲＤＦを製品ＲＤＦとする。
【００２２】
分級された細粒ＲＤＦを可燃物定量供給機１２の排出部３８に設けられたＲＤＦ投入ホッパー２２に戻し、成形機１４の立上げ時に、ＲＤＦ投入ホッパー２２内の細粒ＲＤＦを排出機等の切出装置２０により可燃物定量供給機１２の排出部３８に投入し、成形機１４に導入して成形機１４内に残っているＲＤＦを押し出した後、可燃物ホッパー１０に貯留された可燃物を可燃物定量供給機１２により成形機１４に供給する。
【００２３】
他の方法として、分級された細粒ＲＤＦを切換シュート等の切換手段２６を介して可燃物定量供給機１２の排出部３８に設けられたＲＤＦ投入ホッパー２２に戻し、また該切換手段２６を切り換えて細粒ＲＤＦを可燃物ホッパー１０に戻し、成形機１４の立上げ時に、ごみＲＤＦ投入ホッパー２２内の細粒ＲＤＦを切出装置２０により可燃物定量供給機１２に投入し、成形機１４に導入して成形機１４内に残っているＲＤＦを押し出し、ついで、成形機１４の運転が定常になると、切出装置２０を停止して可燃物ホッパー１０に貯留された可燃物及び細粒ＲＤＦを可燃物定量供給機１２により成形機１４に供給する方法がある。
【００２４】
図２は本発明の実施の第２形態によるＲＤＦの製造装置を示している。可燃物定量供給機１２の排出部３８に切出装置２０を介してＲＤＦ投入ホッパー２２を設け、分級機１８の細粒ＲＤＦ出口２４と可燃物ホッパー１０とを搬送ライン２８を介して接続し、冷却装置１６の出口に切換シュート等の切換手段４４を設け、この切換手段４４とごみＲＤＦ投入ホッパー２２とを搬送手段４０を備えた搬送ライン４２を介して接続している。

【００２６】
冷却装置１６からのＲＤＦの一部を切換手段４４を切り換えることにより可燃物定量供給機１２の排出部３８に設けられたＲＤＦ投入ホッパー２０に戻し、ＲＤＦ投入ホッパー２２に所定量貯留されると弁４６を閉としてＲＤＦを分級機１８に送り、成形機の立上げ時に、ＲＤＦ投入ホッパー２２内のＲＤＦを切出装置２０により可燃物定量供給機１２に投入し、成形機１４に導入して成形機１４内に残っているＲＤＦを押し出し、ついで、成形機１４の運転が定常になると、切出装置２０を停止して可燃物ホッパー１０に貯留された可燃物及び細粒ＲＤＦを可燃物定量供給機１２により成形機１４に供給する。なお、上記の構成では、切換手段４４があれば、弁４６は必ずしも必要ではない。
