APPARATUS AND METHOD FOR TREATING CEMENT KILN EXHAUST GAS
PROBLEM TO BE SOLVED: To provide an apparatus and a method for treating cement kiln exhaust gas, in each of which the cement kiln exhaust gas is treated efficiently at a low cost while effectively utilizing heat energy of eco-cement kiln exhaust gas.SOLUTION: An apparatus 1 for treating cement kiln exhaust gas includes: a heat recovery unit (a boiler) 4 for recovering heat from exhaust gas G1 of an eco-cement kiln 2; a reheating unit 7 for reheating exhaust gas G2 of the heat recovery unit; a catalyst unit 8 for removing harmful substances in the reheated exhaust gas G5; and a wet type dust collection unit (a wet type scrubber) 9 for collecting dust in exhaust gas G6 of the catalyst unit. The apparatus 1 for treating cement kiln exhaust gas can further include: another dust collection unit 6 which is arranged between the heat recovery unit and the reheating unit and used for collecting dust in the exhaust gas G2 of the heat recovery unit and supplying the dust-removed exhaust gas G4 to the reheating unit and can furthermore include a sorting unit (a cyclone) 5 for separating the exhaust gas G2 discharged from the heat recovery unit into coarse powder C and fine powder-containing gas G3 and supplying the fine powder-containing gas to the dust collection unit.SELECTED DRAWING: Figure 1
【課題】エコセメントキルン排ガスの熱エネルギーを有効利用しながら、効率よく低コストでセメントキルン排ガスを処理する。【解決手段】エコセメントキルン２の排ガスＧ１から熱回収する熱回収装置（ボイラ）４と、熱回収装置の排ガスＧ２を再加熱する再加熱装置７と、再加熱された排ガスＧ５中の有害物質を除去する触媒装置８と、触媒装置の排ガスＧ６を湿式集塵する湿式集塵装置（湿式スクラバ）９とを備えるセメントキルン排ガス処理装置１。熱回収装置と再加熱装置との間に、熱回収装置の排ガスＧ２を集塵し、集塵した後の排ガスＧ４を再加熱装置に供給する集塵装置６を備えることができる。熱回収装置から排出された排ガスＧ２を粗粉Ｃと、微粉Ｆを含むガスＧ３とに分離し、微粉を含むガスを集塵装置に供給する分級装置（サイクロン）５を備えることができる。【選択図】図１
