APPARATUS AND METHOD FOR TREATING CEMENT KILN EXHAUST GAS
PROBLEM TO BE SOLVED: To efficiently treat cement kiln exhaust gas at a low cost while effectively utilizing the thermal energy of eco-cement kiln exhaust gas.SOLUTION: A cement kiln exhaust gas treatment apparatus 1 comprises: a heat recovery device (boiler) 4 for recovering heat from exhaust gas G1 of an eco-cement kiln 2; a high-temperature dust collector (high-temperature bag filter) 6 that collects exhaust gas G2 of the heat recovery device 4 and has heat resistance of at least 350°C or higher; a catalyst device 7 for removing harmful substances in exhaust gas G4 of the high-temperature dust collector 6; a calcium-based agent adding device 8 for adding a calcium-based agent to exhaust gas G5 of the catalyst device 7; and a dust collector (high-temperature bag filter) 9 for collecting exhaust gas G6 to which the calcium-based agent has been added. The cement kiln exhaust gas treatment apparatus 1 may include an activated carbon adding device 11 for adding activated carbon AC to exhaust gas G8 of the dust collector 9, and a second dust collector (wet type scrubber) 12 for collecting exhaust gas G9 to which the activated carbon AC has been added.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Ｇ２を集塵し、少なくとも３５０℃以上の耐熱性を有する高温集塵装置（高温バグフィルタ）６と、高温集塵装置６の排ガスＧ４中の有害物質を除去する触媒装置７と、触媒装置７の排ガスＧ５にカルシウム系薬剤を添加するカルシウム系薬剤添加装置８と、カルシウム系薬剤が添加された排ガスＧ６を集塵する集塵装置（高温バグフィルタ）９とを備えるセメントキルン排ガス処理装置１。集塵装置９の排ガスＧ８に活性炭ＡＣを添加する活性炭添加装置１１と、活性炭ＡＣが添加された排ガスＧ９を集塵する第２の集塵装置（湿式スクラバ）１２とを備えることができる。【選択図】図１
