TREATMENT DEVICE AND TREATMENT METHOD FOR CEMENT KILN EXHAUST GAS
PROBLEM TO BE SOLVED: To efficiently treat mercury in the exhaust gas of a cement kiln.SOLUTION: There is provided a cement kiln exhaust gas treatment device 1 comprising: an adsorbent addition apparatus 2, in accordance with the concentration of mercury in the exhaust gas G2 of a cement kiln, selecting whether an adsorbent A adsorbing mercury is added to the exhaust gas G1 of the cement kiln or not; a dust collector 3 of collecting dust included in the exhaust gas G1 of the cement kiln; a plurality of storage apparatuses 6 (6A to 6D) fractionating collected dust D0 in accordance with the addition or not of the adsorbent and storing the same; and carrier passages 10 connected to each of a plurality of the storage apparatuses and carrying the dust D1 to D4 exhausted from the storage apparatuses to the outside of the system of a raw material feeder to the cement kiln or/and a firing apparatus including the cement kiln. The absorbent addition apparatus controls the amount of the adsorbent to the exhaust gas of the cement kiln in accordance with the mercury concentration in the exhaust gas of the cement kiln, and a plurality of the storage apparatuses can perform fractionation and storage in accordance with the addition or not of the adsorbent and in accordance with the addition amount thereof.SELECTED DRAWING: Figure 1
【課題】セメントキルンの排ガス中の水銀を効率よく処理する。【解決手段】セメントキルンの排ガスＧ２の水銀濃度に応じて、水銀を吸着する吸着剤Ａをセメントキルンの排ガスＧ１に添加するか否かを選択する吸着剤添加装置２と、セメントキルンの排ガスＧ１に含まれるダストを集塵する集塵装置３と、集塵ダストＤ０を吸着剤の添加の有無別に分別して貯蔵する複数の貯蔵装置６（６Ａ〜６Ｄ）と、複数の貯蔵装置の各々に接続され、貯蔵装置から排出されたダストＤ１〜Ｄ４をセメントキルンへの原料供給装置又は／及びセメントキルンを含む焼成装置の系外へ搬送する搬送路１０とを備えるセメントキルン排ガスの処理装置１。吸着剤添加装置は、セメントキルンの排ガスの水銀濃度に応じて吸着剤をセメントキルンの排ガスに添加する量を調整し、複数の貯蔵装置は、吸着剤の添加の有無別及びその添加量別に分別して貯蔵することができる。【選択図】図１
