Description

【0001】
【発明の属する技術分野】
この発明は、刈草等の可燃性廃棄物で形成される固形有機物を炭化する装置に関する。
【0002】
【従来の技術】
可燃性廃棄物で形成される固形有機物を炭化する際には、通常、これらを収納容器に収納して炭化炉に装入している。この種の炭化炉では、その天井に開閉蓋を設け、固形有機物を収納した収納容器をクレーンで吊り下げて、天井から炉内に出し入れするようにしたものが多い。このため、この収納容器の炉内への出し入れ作業に多大な手間と時間を要する問題があった。
【0003】
この問題に対して、特開平11−236572号公報と特開2001−247871号公報には、炭化炉の開閉扉を側面に設けて、その床面の奥行き方向に案内レールを敷設し、固形有機物を台車付きまたは台車に搭載された収納容器に収納して、この台車を側面の開閉扉から案内レールで炭化炉内に導入する炭化装置が記載されている。
【0004】
前者は、図4に示すように、炭化炉51と消火炉52とを、それぞれの側面に設けた開閉扉53、54を対向させて離間配置し、これらの間に設けたピット55に、開閉扉53、54の向きと直交方向に延びるレール56を敷設して、収納容器57を搭載した台車58を配給する容器配給台車59をレール56上で運行させるようにしている。炭化炉51、消火炉52および容器配給台車59には、台車58を案内する案内レール60が敷設され、容器配給台車59の左右には折り畳みレール61も設けられている。この折り畳みレール61は、容器配給台車59が炭化炉51と消火炉52の中間位置に来たときに左右に倒されて、炭化炉51と消火炉52の案内レール60に接続され、容器配給台車59上の台車58が、炭化炉51または消火炉52内に導入される。
【0005】
また、後者は、炭化炉の開閉扉を側面に設けて、その床面の奥行き方向に案内レールを敷設し、開閉扉を開けたときに、その前面に案内レールに接続される移動可能なユニットレールを配設して、収納容器を搭載した台車を炭化炉内に導入するようにしている。
【0006】
【発明が解決しようとする課題】
上述した従来の炭化装置は、固形有機物収納容器の台車を炭化炉に出し入れする際に、炭化炉の案内レールに接続されるレールをその都度配設する必要があるので、このレールの配設、撤去と案内レールへの接続に手間がかかる問題がある。
【0007】
前記容器配給台車に折り畳みレールを設けた特開平11−236572号公報に記載された炭化装置は、レールの配設、撤去は比較的簡単であるが、容器配給台車を固形有機物収納容器の台車と直交方向に運行する必要があるので、多大なスペースを必要とする問題がある。
【0008】
例えば、炭化する固形有機物が刈草を圧縮成形したようなものである場合には、嵩張る刈草の運搬を不要とするために、現地で刈草を圧縮成形して、さらにこれを炭化することが考えられている。このような用途の炭化装置は、車両の荷台に搭載できるような、コンパクトなスペースに配置可能なものが望まれる。
【0009】
そこで、この発明の課題は、固形有機物収納容器の台車を炭化炉に容易に出し入れでき、かつ、コンパクトなスペースに配置可能な炭化装置を提供することである。
【0010】
【課題を解決するための手段】
上記の課題を解決するために、この発明は、固形有機物を概ね無酸素雰囲気で加熱して炭化する炭化炉を備え、この炭化炉の開閉扉を側面に設けて、その床面の奥行き方向に案内レールを敷設し、前記固形有機物を台車付きまたは台車に搭載された収納容器に収納して、この台車を前記開閉扉を開けて案内レールで炭化炉内に導入するようにした炭化装置において、前記開閉扉をその下端に設けた水平軸の回りに外側へ水平に回動されるものとし、この開閉扉の内面に上下に延びるレールを設けて、開閉扉を外側へ水平に回動したときに、このレールが前記炭化炉に敷設された案内レールに接続されるようにした構成を採用した。
【0011】
すなわち、開閉扉をその下端に設けた水平軸の回りに外側へ水平に回動されるものとし、この開閉扉の内面に上下に延びるレールを設けて、開閉扉を外側へ水平に回動したときに、このレールが炭化炉に敷設された案内レールに接続されるようにすることにより、開閉扉を開けるのみで炭化炉の案内レールに接続されるレールが配設され、固形有機物収納容器の台車を炭化炉に容易に出し入れでき、かつ、コンパクトなスペースに炭化装置を配置できるようにした。
【0012】
前記開閉扉のレールは、開閉扉の内面に張られたキャスタブル耐火物に埋め込んだ溝形鋼で形成することができる。
【0013】
前記炭化装置を車両に搭載することにより、刈草を圧縮成形した固形有機物を運搬することなく、刈草を刈り取った現地で炭化することができる。
【0014】
【発明の実施の形態】
以下、図1乃至図3に基づき、この発明の実施形態を説明する。図1に示すように、この炭化装置は車両Aの荷台に搭載されており、固形有機物を炭化する炭化炉1と、炭化炉1に加熱ガスを供給する熱風発生装置2と、炭化炉1で発生する熱分解ガスを消煙する消煙装置3と、炭化処理後の炭化炉1内の高温ガスを循環させて冷却する熱交換器4とで基本的に構成されている。
【0015】
前記炭化炉1の開閉扉5は車両Aの荷台の後面側の側面に設けられており、シリンダ6でその下端に設けられた水平軸7の回りに外側へ回動され、支持台8で水平に支持されるようになっている。また、荷台の後端には、固形有機物を収納する台車付き収納容器9を荷台のレベルに昇降させるリフタ10が取り付けられており、荷台の前部には、シリンダ6やリフタ10等を駆動するための発電機11が搭載されている。
【0016】
前記熱風発生装置2には加熱バーナ(図示省略)が組み込まれており、このバーナで加熱された加熱ガスが、配管12で炭化炉1の上部に供給される。炭化炉1で発生する熱分解ガスは、配管13で消煙装置3の前部に導かれ、消煙バーナ14で消煙されて、後部の煙突15から排出される。煙突15は、車両Aの走行時には前方に折り畳まれるようになっている。また、熱交換器4へ高温ガスを循環させる配管16a、16bは、送り出し配管16aが炭化炉1の上部に、戻し配管16bが炭化炉1の下部に接続されており、対流を利用して高温ガスが自然循環されるようになっている。
【0017】
図2に示すように、炭化炉1の内面と開閉扉5の内面にはキャスタブル耐火物17が張られており、炭化炉1の床面には奥行き方向の案内レール18が敷設され、開閉扉5の内面には上下方向に延び、外側へ水平に回動されたときに案内レール18に接続されるレール19が設けられている。
【0018】
図3に示すように、前記レール19は、キャスタブル耐火物17に埋め込まれた溝形鋼20で形成され、台車付き収納容器9のタイヤ21が嵌まり込んで案内されるようになっている。溝形鋼20は鉄筋22で外面の鉄皮23に溶接固定されている。図示は省略するが、炭化炉1の床面の案内レール18も同様の溝形鋼で形成され、キャスタブル耐火物17に埋め込まれている。
【0019】
以下に、この炭化装置における炭化炉1への台車付き収納容器9の出し入れの手順を説明する。図1に示したように、前記リフタ10の上面にも、溝形鋼で形成されたレール24が、車両Aの荷台の前後方向に向けて取り付けられている。
リフタ10上の収納容器9に固形有機物が投入されたのち、リフタ10が荷台のレベルまで上げられるとともに、開閉扉5が外側へ水平に回動され、その内面のレール19が、炭化炉1の案内レール18とリフタ10のレール24に接続される。こののち、リフタ10上の収納容器9が開閉扉5のレール19を通して炭化炉1内に導入され、開閉扉5が閉じられて炭化処理が行なわれる。
【0020】
炭化処理の終了後は、炭化炉1内の高温ガスが熱交換器4で循環されて冷却されたのち、開閉扉5が開けられ、上述した導入手順と逆の手順で、炭化炉1内の収納容器9がリフタ10上に取り出される。
【0021】
上述した実施形態では、炭化装置を車載式の移動可能なものとしたが、本発明に係る炭化装置は、工場等に固定配置してもよい。また、炭化炉の開閉扉のレールは、実施形態のものに限定されることはなく、炭化炉の案内レールに接続され、台車付きまたは台車に搭載された固形有機物の収納容器を、炭化炉内に導入できるものであればよい。
【0022】
【発明の効果】
以上のように、この発明の炭化装置は、炭化炉の側面に設けた開閉扉を、その下端に設けた水平軸の回りに外側へ水平に回動されるものとし、この開閉扉の内面に上下に延びるレールを設けて、開閉扉を外側へ水平に回動したときに、このレールが炭化炉に敷設された案内レールに接続されるようにしたので、開閉扉を開けるのみで炭化炉の案内レールに接続されるレールが配設され、固形有機物収納容器の台車を炭化炉に容易に出し入れでき、かつ、コンパクトなスペースに炭化装置を配置することができる。
【0023】
また、前記炭化装置を車両に搭載することにより、刈草を圧縮成形した固形有機物を運搬することなく、刈草を刈り取った現地で炭化することができる。
