单塔双循环石灰石-石膏湿法脱硫技术的应用

Application of single tower with double circulation typed limestone-gypsum wet flue gas desulphurization technology

石灰石-石膏湿法脱硫技术是目前应用最广的烟气脱硫技术,单塔双循环石灰石-石膏湿法脱硫技术是在传统的单塔单循环脱硫技术的基础上逐步改进发展起来的新技术,该技术克服了效率低、能耗高的缺点,可有效提高脱硫效率,满足最新的排放标准。介绍了单塔双循环脱硫技术的机理,通过某电厂的技术应用,对该技术的发展趋势进行了展望。

Limestone-gypsum wet flue gas desulphurization technology is most widely used at present,and the new single tower with double circulation typed limestone-gypsum wet flue gas desulphurization technology is developed on the basis of traditional single tower with single circulation typed desulphurization technology. This technology overcomes the short comings of high efficiency and low energy consumption of traditional technology,and improves the desulphurization efficiency,which meets the latest emission standards. This paper introduced the mechanism of single tower with double circulation typed desulphurization technology,and prospected the development trend of the technology through the application of a certain power plant.
