Key introduces the CT-121 bubble type spraying tower haze desulphurization craftCT-121 uses the limestone - gypsum (it is in the present world is maturest, most economical, applies broadest desulphurization craft) the aqueous method desulphurization craftIt the sulphur dioxide absorption, the oxidation, neutral, technological processes and so on crystallization as well as dust removal merges to an independent gas - fluid - solid phase reactor in carries onIt the sulphur dioxide absorption, the oxidation, neutral, technological processes and so on crystallization as well as dust removal merges to an independent gas - fluid - solid phase reactor in carries on

与传统的石灰石-石膏湿法烟气脱硫工艺相比，CT-121最大的特点在于鼓泡式吸收塔。它将二氧化硫的吸收、氧化、中和、结晶以及除尘等工艺过程合并到一个单独的气-液-固相反应器中进行。气体进入喷射管，喷射成无数小气泡，形成鼓泡区，从而大大增加了传质面积，提高了脱硫效率。CT-121脱硫工艺能够达到95%以上稳定连续的脱硫率，最低10 以下的粉尘排放率以及优异的可靠性和实用性。问题补充：谁再帮忙给篇，石灰石-石膏湿法烟气脱硫方面的论文文献，谢谢了中英文版的，谢谢了555
