| 中文摘要 |
| 以旋流板塔为脱硫塔,对Na2CO3-Ca(OH)2双碱法烟气脱硫工艺进行了实验研究,对影响脱硫率的主要因素进行考察,如再生液pH值(pH0)、溶液中Na+浓度、SO42-浓度、液气比(L/G)及气体中SO2初始浓度等。结果表明,选择以下工艺条件较为适宜：pH0=7-8,L/G=2-3L/m3,[Na+]≈0.3mol/L. |
| 英文摘要 |
| The Na2CO3-Ca(OH)2 dual alkali FGD process in a Rotating Stream Tray(RST) Scrubber is studied experimentally.Main parameters affecting SO2 removal efficiency are studied for this process.These parameters include pH value of the regenerated solution(pH0),Na+ and SO42- concentration in solution,liquid/gas ratio and inlet SO2 concentration.On the basis of the above results,suitable operating conditions are recommended as follows,pH0=7—8,L/G=2—3 L/m3 and ≈0.3 mol/L. |
