NaClO_(2)溶液同时脱硫脱硝的应用研究

Application study of simultaneous desulfurization and denitration of NaClO_(2) solution

我国可直接燃烧的煤炭资源占到总量的80%以上,排放出SO_(2)和NOx数量可观,对人类环境危害巨大,因此,越来越多的研究者关注烟气中SO_(2)和NOx的脱除问题。其中,可采用不同的吸收剂将烟气中的SO_(2)和NOx污染物同时脱除,即同时脱硫脱硝技术是其极重要的一项分离技术,具有很好的研究前景。本文综述了湿法同时脱硫脱硝的吸收剂分类,其中安全、高效、便捷的NaClO_(2)溶液为主要研究对象,总结其脱除机理,脱除优势,分别从NaClO_(2)单一成分、复合成分脱除,脱除工艺等方面研究讨论,为今后NaClO_(2)应用于同时脱硫脱硝行业的发展提供有价值的参考。

China's coal resources that can be directly burned account for more than 80%of the total,and the amount of SO_(2) and NOx emitted is considerable,which has great harm to the human environment.So more and more researchers pay attention to the removal of SO_(2) and NOx in flue gas.These technologies of the desulfurization and denitration are very important separation technology,mainly using flue gas pollutants SO_(2) and NOx at the same time,which have good research prospect.This paper summarizes the classification of wet desulfurization and denitration absorbent,so we selected the safe,efficient and convenient NaClO_(2) solution as the main research object,emphasized its removal mechanism and removal advantages,we research also the value of NaClO_(2) single component,significance of NaClO_(2) composite components,removaling process,respectively.Finally,providing value reference of the article about NaClO_(2) application should be accepted for enterprises in the development of desulfurization and denitration industry in the future.
