摘要

采用旋流板塔双碱法脱硫工艺，进行了脱硫液中分别添加聚醚硅油、Compound No.3、XHG-248润湿剂促进湿法烟气脱硫（WFGD）系统脱除细颗粒物的试验研究，考察了脱硫液气比、脱硫液温度等对润湿剂作用性能的影响，并进行了协同利用蒸汽相变原理和添加润湿剂促进细颗粒物脱除的试验。结果表明：脱硫液温度对添加润湿剂的作用效果存在显著影响，常温下试验的3种润湿剂均能不同程度促进细颗粒物的脱除，脱硫液温度为45℃时，仅有Compound No.3对细颗粒物脱除有促进作用；同时在旋流板塔盘间添加适量蒸汽和脱硫液中添加Compound No.3润湿剂，可显著促进细颗粒物的脱除，脱除效率可增至65%左右。

Abstract

The addition of wetting agents such as polyether silicone oil

Compound No.3 and XHG-248 into desulfurization solutions to improve the performance of WFGD system for removal of fine particles was investigated in rotating-stream-tray scrubber with Na2CO3 as reagent.The influence of liquid-gas ratio and temperature of desulfurization solutions on role of wetting agents and the performance was studied

and the effect of heterogeneous condensation enlargement and addition wetting agents on fine particles removal efficiency was also examined.The results showed that temperature of desulfurization solutions has significant influence on performance of wetting agents

and the removal efficiency can be improved at normal temperature using anyone of wetting agents studied

but when the temperature of desulfurization solution rises to 45℃ only Compound No.3 is of efficiency.The removal efficiency can be significantly improved by simultaneously adding proper amount of steam between trays and wetting agent Compound No.3

increasing from about 20% to 65%.
