摘要/Abstract

摘要： 实验利用固定床反应法，通过改变气体成分单一变量的方法，研究了无尘条件下与含尘条件下高炉炉顶煤气的气体成分变化对低温钙基脱氯剂脱除HCl的影响.结果表明:高炉炉顶煤气中，CO₂含量增加，含尘条件下与无尘条件下脱氯剂的脱氯效果均明显变差;CO含量和N₂含量增加，含尘与无尘条件下的脱氯环境都有着明显的改善;H₂含量变化，含尘与无尘条件下脱氯剂的脱氯效果均没有明显的变化;含尘条件下脱氯剂的穿透时间比无尘条件下高出40~60min左右，穿透氯容量百分比高出6%左右.

关键词: 高炉炉顶煤气, HCl气体, 脱氯剂, 穿透时间, 穿透氯容量

Abstract: Using fixed-bed reaction method， the influence of blast furnace top gas composition on HCl removal by low temperature Ca-based antichlor under none-dust and with-dust conditions was studied through changing individual variable of the gas composition. The results showed that when the content of CO₂ in blast furnace top gas increased， the dechlorination efficiency decreased under both none-dust and with-dust conditions. However， when the content of CO and N₂ increased， the dechlorination efficiency improved substantially under both none-dust and with-dust conditions. It was also found that the dechlorination’s breakthrough time was 40~60min more than that under none-dust condition， while the capacity of reacted-chlorine increased 6% under with-dust one.

Key words: blast furnace top gas, HCl gas, dechlorination agent, breakthrough time, capacity of reacted-chlorine
