摘要
介绍了双塔双循环脱硫系统优化试验情况,结合优化试验结果分析了不同运行参数对双塔双循环脱硫系统的影响,并优选出了最佳运行工况。结果表明:双塔双循环脱硫系统的脱硫效率可以达到99.2%以上;不同负荷条件下应选择合适的运行工况;按照优选的运行参数运行可以大大节约运行成本;双塔双循环工艺的脱硫效果完全满足超低排放要求。
Optimization tests of the series absorption tower are conducted in the work. The effect of the series absorption tower on different operating conditions is analyzed based on the optimization test results, and the best operation condition is selected. The results show that the desulfurization efficiency can reach over 99.2% using the series absorption tower. The suitable operation condition should be chosen in different load conditions accordingly to save the operation cost greatly, and the desulfurization effect of the series absorption tower fully meets the requirement of ultra-low emission.
