Description

【０００１】
【産業上の利用分野】
本発明はコークス炉の装炭口および炭化室内に付着しているカーボンを除去する装置に関する。
【０００２】
【従来の技術】
図４および図５に示すように従来からコークス炉１の炉頂に敷設せるレールＲ上を走行する石炭装入車あるいは石炭装入車に牽引されて又は自力で走行する台車２にブロワ３と、内外二重筒４1、４2からなり内筒４1の頂部を台車のフレー ムＦに固設し、外筒４2の上端部をロープ巻取装置５で吊り下げてガイド受金物 ６1、ガイド６2を介してテレスコピック式に伸縮可能のランス４を積載し、ランス４の外筒４2をガイド受金物６1に案内伸張して装炭口７から炭化室８内へ挿入し、ブロワからの空気をダクト９、ランス内筒４1、外筒４2、を経由して外筒４2の周面に設けた空気吹出口１０、１０・・から炭化室内に吹き込んで炭化室に 付着しているカーボンＣ1、Ｃ2、Ｃ3を燃焼除去する装置は公知である。なお、 １１はブロワの吸引口側に設置されているサイレンサ、１２は梯子、１３は装入口蓋である。
【０００３】
また、特開平６ー３２２３７４号公報に開示されているように、コークス押出機の押出ラムのラムヘッド背部に噴出口を上方に向けてノズルを設置し、押出機に搭載している圧縮空気供給設備からの圧縮空気を該ノズルから噴射させて装炭口７の周辺に付着しているカーボンＣ3を空圧で吹き飛ばし除去することも公知 である。
【０００４】
上記従来の装置は炉内のカーボンを除去するために炭化室に付着せるカーボンの燃焼除去には炉頂の走行台車に設置している装置で行い、装炭口周辺の付着カーボンの吹き飛ばし剥離除去にはコークス押出機に設置している装置で行なっており、装置が分散配置されているため作業手順等において不便であった。また、装炭口周辺のカーボン剥離除去に際し、圧縮空気を下から上向きに噴射させると装炭口蓋１０が開放されていると炉頂を汚損させる欠点があった。
【０００５】
【発明が解決しようとする課題】
本発明は炭化室の壁面と天井および装炭口に付着せるカーボンの燃焼除去をする装置と、装炭口周辺の付着カーボン吹き飛ばし剥離除去する装置を一箇所に集めて炭化室に付着したカーボンを燃焼と剥離により除去効果を向上させるとともに、装置をコンパクト化して作業手順を便利にし、さらに、装炭口周辺のカーボン剥離除去作業に際し炉頂を汚損させない装置を提供することを目的とする。
【０００６】
【課題を解決するための手段】
コークス炉１の炉頂を走行する石炭装入車等の走行台車２にブロワ３と該ブロワに接続しテレスコピック式に伸縮自在の内外二重筒４1 、４2 からなるランス４を積載し、ランス外筒４2 に穿設した吹出口１０、１０・・から空気をコークス炉炭化室８内に吹き込んで該炭化室８内に付着しているカーボンを燃焼除去する装置において、前記走行台車２に圧縮空気供給装置１４を積載すると共に、ランス内筒４ 1 の内部に圧縮空気供給管１６を配し、ランス外筒４ 2 は、内部に、圧縮空気供給管１６が挿入される内筒部１７を備え、圧縮空気供給装置１４からの圧縮空気を、圧縮空気供給管１６と内筒部１７とを経由してランス外筒４ 2 の下部に設けた圧縮空気噴射口１９から噴射させて、装炭口７に付着しているカーボンを剥離除去することを特徴とする。
【０００７】
【発明の実施の形態】
図１〜図３により本発明装置の実施の形態を説明する。（従来装置と同一の部品には同一の符号を付している。）２はコークス炉１の炉頂に敷設されているレールＲ上を走行する台車で、該台車は石炭装入車の台車の一部でもよく、石炭装入車に牽引され、あるいは自走式の台車でもよい。３は炉内に燃焼空気を送給するためのブロワである。４は内筒４1に外筒４2が外装されテレスコピック式に伸縮できるランスであって、内筒４1の上部は台車２のフレームＦに固設されてお り、外筒４2の上端部はロープ巻取装置５のワイヤロープＷで吊り下げられてい る。外筒４2の外周壁にガイド６2が溶接等により取り付けられており、該ガイド６2は台車のフレームに取り付けられているガイド受金物６1により案内されている。９はブロワ３の吐出口とランス内筒４1を連結しているダクトである。
【０００８】
１４は台車２上に積載されている圧縮空気供給装置、１５は圧縮空気供給配管、１６は基部が前記圧縮空気供給配管１５に接続されランス内筒４1内に架設さ れている圧縮空気供給管である。ランンス外筒４2は上部が開口している二重筒 構造に形成されており、内筒部１７の上部は前記圧縮空気供給管１６の下部に挿入されており、下部はマニホールド１８に形成され外筒４2に穿設されている穴 に連通し圧縮空気噴射口１９となっている。そして、ランンス外筒４2がロープ 巻取装置によりランス内筒４1に対して摺動するとき、ランンス外筒４2の内筒部１７は圧縮空気供給管１６の外周面を摺動する構造となっており、外筒４2の周 面に設けた空気吹出口１０、１０・・からはブロワ３からの燃焼空気が吹き出し、圧縮空気噴射口１９からは圧縮空気供給装置１４からの圧縮空気が噴射する構造となっている。
【０００９】
上記本発明装置によるカーボン除去作業について説明する。装炭口７近傍に付着しているカーボンＣ3の剥離除去作業に際しては、図２に示すようにランンス 外筒４2を降下させて、該ランス外筒４2下部の圧縮空気噴射口１９を装炭口７の付着カーボンに対向する位置に位置させる。そして、圧縮空気供給装置１４からの圧縮空気を噴射口１９から噴射させると装炭口７近傍の付着カーボンＣは剥離されきれいに清掃される。この際、圧縮空気は装炭口７の上方から斜め下方に向けて噴射されるので剥離されたカーボンは炉頂に舞い上がることなく炉底に落下するので炉頂面を汚損しない。
【０００９】
次に炭化室壁面に付着しているカーボンの燃焼除去作業について説明する。該作業は図５に示す従来装置と同様であって、ランンス外筒４2を図２の位置から さらに図３に示す位置まで降下させる。そしてブロワ３からの燃焼空気をダクト９、ランス内筒４1、ランンス外筒４2と内筒部１７とで構成される流路２０を経てランス外筒４2の周面に設けた空気吹出口１０、１０・・から炭化室８内に吹 き込んで炭化室に付着しているカーボンＣ1、Ｃ2を燃焼除去させるものである。
【００１０】
【発明の効果】
本発明は、炭化室に付着しているカーボンを燃焼除去をする装置と装炭口周辺の付着カーボンを剥離除去する装置を炉頂を走行する台車に纏めたので除去効果を向上させることができるとともに、装置をコンパクト化できる。さらに、装炭口周辺のカーボン除去作業の際炉頂を汚損させることがない。
