活性炭纤维与柱状活性炭用于烟气脱硫的对比实验

在活性炭法烟气脱硫工艺中，为了有效地提升系统运行的综合性能，通过实验将活性炭纤维（ACF）与普通的柱状颗粒活性炭（GAC）的各项特性进行了对比，实验结果表明，在同样的工作条件下，ACF的吸附系数比GAC提高16．6倍，损耗减少到GAC的1／14，脱附效率棕达一99．8％以上，证明了采用ACF作为工质可以大大送还和吸附剂用量，显著降低补充新工质的次数，减少设备的投资和运行费用，因而使活性炭法烟气脱硫系统在运行的经济性，可靠性和持久性方面均具有比较明显的优势。

Contrasting Experiment between Activated Carbon Fiber and Granular Activated Carbon in Desulfurization from Flue Gas

In order to improve the desulfurized capacity of the system from flue gas by using activated carbon, a series of experiments were made to compare the difference of performance between using activated carbon fiber (ACF) and using granular activated carbon (GAC). Experiments show that under the same working conditions, adsorption factor of ACF was 16 6 times as high as that of GAC, the adsorbent loss ratio of ACF was 1/14 of that of GAC, and the desorption efficiency can reach 99 8%. Conclusions were drawn that compared with the traditional methods of desulfurization from flue gas, the use of ACF can greatly economize adsorbent, obviously reduce the frequency adding new adsorbent, and reduce the equipment investment and operating cost, Therefore, the new method has obvious advantages in aspect of economization reliability and durability in system operating.
