| 中文摘要 |
| 实验研究了废大理石粉作为脱硫剂的湿法烟气脱硫工艺,分析了其吸收SO2的传质反应机理.试验了不同液气比(L/G)、吸收浆液pH值和进气SO2浓度等主要参数对脱硫率的影响,并对实验结果进行了分析.结果表明,选择以下操作条件较为适宜:pH0=5.5～6.5,L/G=3L/m3,a=2%;以上工艺条件下,在进气SO2浓度为1000ml/m3时,脱硫率达60%以上.本文还讨论了废大理石粉作为脱硫剂的工业应用前景. |
| 英文摘要 |
| The wet FGD process with waste marble was studied experimentally, and the mass transfer reaction mechanism was analyzed. Main parameters including liquid/gas ratio, pH value of the absorbent slurry and inlet SO2 concentration, etc. affecting SO2 removal efficiency were studied for the process. The results show that the suitable operating conditions were recommended as follows: pH0=5.5～6.5, L/G=3L/m3, a =2%; the sulfur dioxide removal efficiency can reach more than 60% when the inlet SO2 concentration was 1000ml/m3.In addition, the industrial application potential for this process was discussed. |
