| 中文摘要 |
| 针对石灰乳直接脱硫存在的结垢问题,提出了亚硫酸钙脱硫法,并研究了该法的反应机理及主要因素对脱硫率的影响,确立了适宜的操作条件.即在空塔气速2.75m/s、L/G=3.0 L/m3、固含量6.7%、气温31℃、进口SO2初始体积分数1500×10-6、进塔液pH=8.0并维持不变的条件下,连续运转中的脱硫率可达87%.该法从理论上解释、实践上解决了石灰湿法脱硫过程中设备的结垢问题,其实质是以全钙基物质为脱硫剂的新型间接石灰法. |
| 英文摘要 |
| Directing to the scaling problem lying in wet desulfurization with lime slurry, a method of desulfurization with calcium sulfite was proposed. Reaction mechanism and the effects of different conditions on desulfurization efficiency were studied. The optimum conditions were obtained, i.e. air velocity of 2.75m/s in empty tower, L/G=3.0 L/m3, solid content 6.7%, air temperature 31℃, concentration inlet of SO2 1500×10-6 and inlet suspension pH of 80. Under the conditions, the desulfurization efficiency was about 87%. The presented method theoretically and practically solved the scaling problems, which is a novel indirect lime method with Ca contained material as desulfurization agent. |
