CEMENT KILN EXHAUST GAS TREATMENT APPARATUS AND TREATMENT METHOD
PROBLEM TO BE SOLVED: To efficiently treat a cement kiln exhaust gas at a low cost while effectively utilizing heat energy in an ecological cement kiln exhaust gas.SOLUTION: A cement kiln exhaust gas treatment apparatus 1 comprises: a heat recovery device (boiler) 4 recovering heat from the exhaust gas G1 of an ecological cement kiln 2; a high temperature dust collector 7 collecting dust D in the exhaust gas G3 of the heat recovery device 4; a catalyst device 8 removing harmful matter in the exhaust gas G4 of the high temperature dust collector 7; and a wet dust collector (wet scrubber) 9 performing the wet dust collection of the exhaust gas G5 of the catalyst device 8. A calcium component addition device 6 adding a calcium component into the exhaust gas of the heat recovery device 4 can be provided. A classifier (cyclone) 5 separating the exhaust gas G2 exhausted from the heat recovery device 4 to coarse powders C and the gas G3 including fine powders and supplying the gas including the fine powders to the high temperature dust collector 7 is preferably provided.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４の排ガスＧ３中のダストＤを捕集する高温集塵装置７と、高温集塵装置７の排ガスＧ４中の有害物質を除去する触媒装置８と、触媒装置８の排ガスＧ５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４の排ガスにカルシウム分を添加するカルシウム分添加装置６を備えることができ、熱回収装置４から排出された排ガスＧ２を粗粉Ｃと、微粉を含むガスＧ３とに分離し、微粉を含むガスを高温集塵装置７に供給する分級装置（サイクロン）５を備えることが好ましい。【選択図】図１
