摘要
石灰、石灰石是最常用的湿法脱硫剂.从反应机理、运行控制指标、液气比和钙硫比(化学过量比)、浆液循环池等方面对其性能作了比较.两者的脱硫机理、运行控制指标不同,受温度的影响程度也不同.两系统的最小液气比分别为10.0和5.6,化学过量比分别为1.05～1.15和1.25～1.60.前者的脱硫效力优于后者.
Lime and limestone are the most common wet SO2 absorbent. Their property comparison is made in several aspects, such as reaction mechanism, control standard, liquid/ gas ratio, chemical excessive ratio and so on. They are different in desulfurization mechnism and control standards. Reaction temperature has incoordinately influence on both systems. The liquid/gas ratio and chemical excessive ratio of limetone system are 10 and 1.25- 1.60. The liquid/gas ratio and chemical excessive ratio of limetone system are 5.6 and 1.05-1.15 otherwise. The desulfurization efficiency of lime is better than that of limestone.
