REDUCTION OF DISCHARGE OF MERCURY FROM CEMENT FACTORY
PROBLEM TO BE SOLVED: To provide a method for reducing the discharge of mercury from a cement factory.SOLUTION: The cement factory at least comprises: a kiln 6; a fine particle recovery device 10; recovered fine particles; an exhaust gas flow 8b; a heater; and a mercury scrubber, in which the heater and the mercury scrubber lie on the upstream. The method comprises: a stage where the recovered fine particles are guided through the heater so as to form volatilized mercury species; a stage where the recovered fine particles from the heater are guided to the downstream toward the kiln; and a stage where the volatilized mercury species are guided to the mercury scrubber. An exhaust gas flow 8c flows out from the fine particle recovery device 10, and an optionally selective step includes the injection of a mercury absorbent at one or more points among the kiln 6 and the fine particle recovery device 10.SELECTED DRAWING: Figure 1
【課題】セメント工場からの水銀の排出量を削減するための方法を提供する。【解決手段】少なくとも、キルン６、微粒子回収デバイス１０、回収された微粒子、排ガス流８ｂ、加熱器、および水銀スクラバーを含み、加熱器および水銀スクラバーはキルンから上流にあり、回収された微粒子から揮発した水銀種を形成するように、回収された微粒子を加熱器を通して誘導することと、加熱器からの回収された微粒子をキルンに向かって下流に誘導することと、揮発した水銀種を水銀スクラバーに誘導することとを含み、排ガス流８ｃは、微粒子回収デバイス１０から流出し、加熱器内に誘導されず、任意選択的なステップは、キルン６と微粒子回収デバイス１０との間の１つ以上の地点で水銀吸着剤を注入することを含む方法。【選択図】図１
