添加剂在喷雾干燥脱硫中的应用
Application of Additives in Spray Drying Absorption Flue Gas Desulfurization
【摘要】 使用添加剂提高喷雾干燥脱硫系统的脱硫效率具有操作简单、成本低、功效明显等优点。本文通过试验研究了己二酸、氯化钙、氯化镁和氯化钠对喷雾干燥脱硫系统脱硫效率的影响,并分析了脱硫效率提高的机理。结果表明,加入少量添加剂即可明显提高系统的脱硫效率,从而降低操作费用,提高其经济性。
【Abstract】 Using additive to improve desulfurization efficiency in spray drying absorption flue gas desulfurization(SDAFGD) has many merits,such as simple operation,low cost and obvious effect.In this paper,the influence of HOOC(CH2)4COOH,CaCl2,MgCl2,NaCl on SDAFGD had been studied.The mechanism of improving desulfurization efficiency had been analyzed.The result indicated that the SO2 removal efficiency was improved and the expenditure was reduced when additives were added into Ca(OH)2 slurry in SDAFGD.
