摘要
SO_(2)由于对人类健康和生态环境的有害影响,成为当前人们关注和研究的焦点。吸附法脱除SO_(2)无含硫废水产生且能实现硫资源的回收利用,是SO_(2)治理的有效方法,其中吸附材料的选择是吸附系统设计和开发的关键。本文对近年来固体吸附材料脱除SO_(2)的研究现状进行了综述,重点梳理和分析了不同类型固体材料对SO_(2)的吸附性能及吸附机理,并进一步指出了不同类型固体材料在SO_(2)吸附脱除过程中所存在的问题。最后结合固体材料吸附脱除SO_(2)研究现状提出吸附法脱硫领域目前有待解决的主要问题,以期为吸附法脱硫技术的开发提供参考,并建议未来吸附法烟气治理领域向着一体化脱除多种烟气杂质的方向发展。
SO_(2)Emission has become an important issue,due to the harmful impact on human health and the ecological environment.Adsorption is an effective SO_(2)removal method that could avoid producing sulfur-containing waste water and realize the recycling of sulfur resources.Adsorption materials play the key role in the design and development of the adsorption system.In this paper,researches about SO_(2)removal by solid adsorption materials are reviewed and their adsorption performance,mechanisms and shortcomings are analyzed.Finally,the main problems for SO_(2)removal by adsorption are proposed to provide references for the development of adsorption desulfurization technology.It is suggested that the future adsorption purification of flue gas should be towards simultaneous removal of various flue gas impurities.
