摘要
通过研究高炉炉顶煤气中CO_2、H_2O和炉尘对低温钙基脱氯剂脱除HCl的影响发现:高炉炉顶煤气中,CO_2和H_2O含量增加,脱氯效果不同程度地变差;在不同位置的高炉炉顶煤气含炉尘范围内,重力灰含量增加,脱氯效果急剧变差;布袋灰含量低于10mg/m3时,布袋灰的含量增加脱氯剂的脱氯效果在一定程度上略有改善。
According to the study on influence of CO2,H2O and dust on HCl removal using low temperature Ca-based dechlorination agent from the blast furnace top gas,we get the conclusion as follows： when the content of CO2 and H2O in blast furnace top gas increased,dechlorination agent＇s efficiency was getting worse in various degree; in the range of the content of dust in blast furnace top gas at different sites,when the content of gravitational dust increased,dechlorination agent ＇s efficiency was getting worse quickly; when the content of gravitational dust got less than 10 mg / m^3,dechlorination efficiency was getting better to some extent with the content of bag dust increasing.
