Effect of Dust on HCl Removal in the Process of the Blast Furnace Top Gas

College of Metallurgy & Energy, North China University of Science and Technology, Tangshan 063009, Hebei, China

摘要

摘要: 通过研究炉尘对高炉炉顶煤气中HCl脱除过程的影响发现:高炉煤气中布袋灰含量在小于5 mg/m³的范围升高时,高炉炉顶煤气的脱氯效果得到改善;粒度在小于38μm范围内,粒径增加可以小幅改善脱氯效果,但粒度过大时脱氯效果迅速变差。高炉炉顶煤气中HCl气体脱除工艺适宜的实施地点应该选择在布袋除尘器后,布袋灰经过一定的提纯处理后可作为高炉炉顶煤气脱氯剂的活性添加剂。高炉煤气中的重力灰却会恶化高炉炉顶煤气的脱氯效果。

Abstract: In this paper the effect of furnace dust on the HCl removal in the top gas of blast furnace had been investigated.When ash content in gas baghouse increases within the level less than 5 mg/m³,the HCl removal can be improved.When the particle size of dust is less than 38 μm,increasing size can slightly improve the dechlorination effect,however,excess size will lead to rapid removal effect decreasing. The suit-able location for installing HCl removal equipment shall be the downstream of cloth bag dust remover, and the baghouse ash through purification can be used as an active additive into blast furnace top gas dechlorination agent.The gravity dust will deteriorate the effect of removing chlorine in the blast furnace top gas.
