【摘要】 白泥来源于碱法制浆造纸过程中的副产物,具备吸收性能强、反应活性高、残余碱度高等优势,可代替石灰石在燃煤电厂用作烟气脱硫,为电厂带了可观的经济效益,同时有助于实现电厂碳减排的目标。尽管很多学者对白泥脱硫技术的可行性进行了初步研究,白泥脱硫技术也逐渐被电厂接受,但由于造纸白泥与石灰石在理化性质上存在差异,在实际应用过程中出现了很多问题。阐述了国内外造纸白泥处理现状,重点对白泥脱硫技术的发展及对存在问题进行分析,为燃煤电厂应用白泥脱硫技术提供理论支持。更多还原

【Abstract】 Lime mud is derived from by-products in the process of alkali pulping and papermaking. With its advantages of strong absorption performance, high reactivity and high residual alkalinity, it is used as flue gas desulfurization in coal-fired power plants instead of limestone, which can bring considerable economic benefits to the power plants and help to achieve the goal of carbon emission reduction in the power plants. Although many scholars have made preliminary studies on the feasibility of lime mud desulfurization technology, lime mud desulfurization technology has been gradually accepted by power plants, but due to the difference in physical and chemical properties between lime mud and limestone, there are many problems in the practical application process. This paper describes the status of papermaking lime mud treatment at home and abroad, focuses on the development of lime slime desulfurization technology and analysis of the existing problems, to provide theoretical support for the application of lime mud desulfurization technology in coal-fired power plants.更多还原
