The method of Ca-Ca double alkali desulfurization and its application in industry

摘要：探讨了不同pH值下石灰湿法脱硫的反应机理, 在此基础上提出了钙钙双碱法.研究了影响钙钙双碱法脱硫效率的因素.工业应用结果表明, 该法由于在理论上解释、实践中解决了石灰湿法脱硫设备结垢问题, 因而能连续、稳定脱硫, 脱硫率达80%-96%.与传统钠钙双碱法比较, 新方法物料单一, 工艺、设备简单, 不耗钠碱, 投资和运行费用更低.

Abstract：The reaction mechanism of wet desulfurization with lime slurry under different pH values was discussed, the Ca-Ca desulfurization method was given out, and some influential factors of this method were studied. Industrial application results showed that: the desulfurization efficiency reached to 80%—96%, and the problems of filth forming in desulfurizing equipments were not only correctly explained theorelically but also resolved praticatty. Thus this method presents many advantages: the material during operating is single, the process and equipments are brief, it doesn't consume natrium-based alkali and both the investment and the running expenses are low contrasting to Na-Ca double {alkali.}
