【摘要】：本文介绍了目前国内外主要的烟气脱硫技术；分别从技术原理、工艺流程、吸附剂的制备和再生、副产物的回收利用等方面对活性焦脱硫技术进行了详细说明；在分析活性焦脱硫技术在国内应用情况的基础上,结合工程实例,对电厂烟气脱硫采用活性焦脱硫技术、石灰石—石膏湿法脱硫技术、循环流化床半干法脱硫技术、氨法脱硫技术从技术方面和经济方面进行了比较,经过比较可知,活性焦脱硫技术存在许多优点,可实现脱硫脱硝一体化,且副产物的回收利用有很大的市场需求。随着活性焦脱硫技术在国内的逐步推广与应用,活性焦生产工艺的不断改进,活性焦脱硫技术必在国内被广泛应用。
[Abstract]:In this paper, the main flue gas desulfurization technologies at home and abroad are introduced in detail from the aspects of technical principle, technological process, preparation and regeneration of adsorbent, recovery and utilization of by-products, etc. On the basis of analyzing the application of active coke desulfurization technology in China, combined with engineering examples, active coke desulfurization technology, limestone gypsum wet desulfurization technology and circulating fluidized bed semi-dry desulfurization technology are used in flue gas desulfurization of power plant. The technology of ammonia desulphurization is compared from the technical aspect and the economic aspect. The comparison shows that the active coke desulfurization technology has many advantages, it can realize the integration of desulphurization and denitrification, and there is a great market demand for the recovery and utilization of by-products. With the gradual extension and application of activated coke desulfurization technology in China and the continuous improvement of active coke production technology, activated coke desulfurization technology will be widely used in China.
