  • 摘要: 为了进一步提高密相塔半干法脱硫工艺的脱硫效率和脱硫剂利用率,研究了系统含湿量对脱硫效率的影响。首先,通过模拟实验探索了系统含湿量与脱硫剂失效时间的关系,然后利用MATLAB编程软件计算了系统中CaO脱硫剂利用率与系统含湿量的关系。结果表明,脱硫剂CaO的失效时间随着系统含湿量的增加而逐渐增大;系统中SO2脱除量和CaO脱硫剂利用率均随着含湿量的增加而显著提高,当系统含湿量为9%时,分别达到1 210 mg和70%。在实际工程中可结合链式搅拌器的使用,进一步提高脱硫剂的利用率和脱硫效率,满足日益严格的排放标准。
    Abstract: In order to further increase the desulfurization efficiency and sorbent utilization efficiency of dense flow semidry flue gas desulphurization technology, the effect of moisture content on the desulphurization efficiency was studied. First, the relationship between the moisture content and failure time of sorbent was studied. Then, the relationship between the CaO utilization efficiency and the moisture content was calculated with MATLAB. The results showed that the failure time of CaO increased with the moisture content; the removal amount of SO2 and the CaO utilization efficiency increased with the moisture content. When the moisture content was 9%, the removal amount of SO2 and the CaO utilization efficiency can reach 1 210 mg and 70%, respectively. In actual engineering, the utilization of chain blender can further increase the sorbent utilization efficiency and desulphurization efficiency to meet more rigorous SO2 emission standard.
