摘要/Abstract

摘要： 随着“碳达峰”、“碳中和” 目标的提出，将促使企业更加关注二氧化硫的脱除问题。由于粒状干法脱硫剂材料廉价易得、制备方法简单、脱硫性能高、易于操作等特点，粒状干法脱硫工艺将会成为未来烟气脱硫的发展趋势。本文介绍了粒状干法脱硫剂中需要使用的黏结剂和造孔剂，在脱硫剂中添加黏结剂可以增加脱硫剂的机械强度和脱硫效率使脱硫剂不易粉化；在脱硫剂中添加造孔剂可以提高脱硫剂的比表面积和孔隙率，从而增加脱硫剂与二氧化硫的接触机遇，进而提高脱硫剂的脱硫效率。在粒状干法脱硫剂中添加廉价易得的黏结剂和造孔剂提高脱硫剂的脱硫效率、降低成本是今后的发展方向。

Abstract: With the "carbon peaking" and "carbon neutrality" goal proposed, the enterprises have to pay more attention to the removal of sulfur dioxide. Due to the characteristics of low cost, simple preparation, high desulfurization performance and easy operation, the granular dry desulfurization process will become the trend of flue gas desulfurization in the future. Binder and pore-forming agent used in granular dry desulfurizer were introduced. Adding binder to the desulfurizer could increase the mechanical strength and desulfurization efficiency of desulfurizer and make desulfurizer difficult to pulverize. Adding pore-forming agent to desulfurizer could increase its specific surface area and porosity, thus increasing the contact chance between desulfurizer and sulfur dioxide, and improving the desulfurization efficiency. By adding binder and pore-forming agent to granular dry desulfurizer, the utilization rate of granular dry desulfurizer could be greatly improved, so the cost of desulfurization was reduced. In the future, it is the development trend to add cheap binder and pore-forming agent into granular dry desulfurizer to improve the mechanical strength and desulfurization efficiency of desulfurizers and reduce the cost.

Key words: granular dry desulfurizer, binder, pore-forming agent
