Abstract
Description
すなわち、本発明に係る給塵装置は、廃棄物をガス化するガス化炉に廃棄物を供給する給塵装置であって、ケーシングと、前記ケーシング内に設けられた二本の供給スクリューと、前記二本の供給スクリューの間に、複数の突起を備え正逆繰り返し回転する中間軸とを備えたことを特徴とする。
本発明によれば、ケーシングが絞り込まれていることにより、廃棄物の定量搬送が可能となる。
本発明によれば、絞り込み位置において突起の形状及び供給スクリューの螺旋ピッチを切り換えることにより、上流側での圧密を防止することができる。
本発明によれば、軸シール部から未燃ガスが漏れた場合、未燃ガスを拡散させることなく回収することができる。
流動床ガス化炉6は、ガス化炉本体7と、ガス化炉本体7下部に設けられた流動層8とを有する。流動層8を形成するため、一次燃焼用空気を下方から吹き出し、熱の伝達手段である流動媒体としての砂を流動化させている。
流動床ガス化炉6に投入された廃棄物は流動層8内で乾燥、熱分解される。この間、不燃物52が流動砂と共に排出される。熱分解により廃棄物はガス、タール、チャー(炭化物)に分解される。タールは、常温では液体となる成分であるが、ガス化炉内ではガス状で存在する。チャーは流動床ガス化炉6の流動層8内で徐々に微粉化され、ガス及びタールに同伴して熱分解ガス51として図示しない旋回溶融炉へ導入される。
給塵装置1は、給塵ホッパー5から供給される廃棄物を押し出すプッシャー式給塵装置2と、プッシャー式給塵装置2から押し出された廃棄物が投入される接続シュート3と、接続シュート3の下部に設けられ、接続シュート3に貯留された廃棄物を流動床ガス化炉6に排出するスクリュー式給塵装置4とを有する。
以下、プッシャー11のスライド方向の前進方向を前方(図2における右方)といい、後退方向を後方という。また、これらを総称して前後方向という。
接続シュート3の上面27には、複数の消火装置13が設けられている。消火装置13は、水噴霧型の消火装置であり、ノズルにより噴出した水滴の霧で、対象物を覆い消火を行う装置である。消火装置13のノズルは、接続シュート3の上面27より下方に向けられており、スクリュー式給塵装置4を消火するように設定されている。消火装置13は、図示しないポンプなどの給水設備と接続されている。
中間軸16は、油圧モーター18によって駆動される。中間軸16は、切り換え弁(不図示)を制御することにより正逆回転を繰り返すように設定されている。
図4に示すように、中間軸16は、円筒状の中間軸本体16bと、中間軸本体16bの外周に突設された複数の突起24とからなる。
突起24は、中間軸16の周方向に沿って複数個形成された突起列が軸方向に複数列形成された構成である。突起列は、90°間隔で形成された4つの突起24により構成されている。また隣り合う突起列同士が互い違いになるように配置されている。本実施形態では、突起列は8列であり、そのうち前方三列(下流側)の突起が三角錐形状の三角突起24aであり、後方五列(上流側)の突起が四角柱形状の四角突起24bである。
図9に示すように、回転センサー38は、軸16aの周方向に沿って描かれた、縞模様39と、縞模様39の上方に設置された光センサー40とからなる。縞模様39は、軸の回転に伴い白部分と黒部分が交互に現れる様に描かれている。光センサー40は、反射型の光センサーであり、縞模様39に当たって反射した光量を検知し、軸16aが回転しているか否かを判断するように設定されている。
なお、本実施形態においては、縞模様39は軸16aに描かれているが、軸16aと油圧モーター18との間にカップリングを設け、このカップリングに縞模様を描いてもよい。
まず、図1に示すように、廃棄物50が給塵ホッパー5から供給され、ケーシング10を介して、廃棄物が接続シュート3に流入する。この際、廃棄物は、適宜プッシャー式給塵装置2によって接続シュート3に向かって押し出されている。
次いで、廃棄物は、絞り部36より下流側に搬送される。ここで、廃棄物は圧縮されるが、先端が鋭利な三角突起24aにより攪拌されるため圧密しない。また、絞り部36より下流においては、スクリュー15cの螺旋ピッチが大きくなっていることにより、ケーシング19の絞りに伴い廃棄物が圧密されることが防止される。
また、ケーシング29の内面に振れ止め41が設けられているため、供給スクリュー15の先端の軸振れを防止することができる。
また、ケーシング19が常温硬さがHB400以上の耐摩耗鋼によって形成されていると共に、供給スクリュー15のスクリュー15cに耐摩耗硬化肉盛処理が施されていることによって、廃棄物とスクリュー15c及びケーシング19との接触摩耗による損傷を防止することができる。
さらに、中間軸16の軸16aに、回転センサー38が設けられて入ることにより、中間軸16の左右反転動差不良を検知することができる。
