REDUCTION OF CEMENT KILN EXHAUST GAS CONTAMINATION
PROBLEM TO BE SOLVED: To provide a method for treating cement kiln exhaust gas including a volatile heavy metal such as mercury.SOLUTION: A cement kiln exhaust gas flow 22 is supplied through a duct 30. A water soluble alkali earth metal polysulfide stored in a container 50 is supplied through a pipe 52, and then poured or injected from a nozzle 48, then the cement kiln exhaust gas flow and the water soluble alkali earth metal polysulfide are mixed and react so as to form a mixed flow, and a sulfide of metal such as generated mercury sulfide is removed on a fine particle collection system 40.
【課題】水銀のような揮発性重金属を含むセメントキルン排気ガスを処理する方法の提供。【解決手段】セメントキルン排気ガス流２２は、ダクト３０を通して供給し、容器５０に貯留された水溶性アルカリ土類金属多硫化物は、パイプ５２を通して供給され、ノズル４８から注入又は噴射し、セメントキルン排気ガス流と水溶性アルカリ土類金属多硫化物は混合流を形成する様に混合して反応し、生成した硫化水銀の様な金金属の硫化物を微粒子収集システム４０において除去する方法。【選択図】図１
