摘要
目前广泛应用的石灰石—石膏法脱硫工艺造成大量的脱硫石膏堆存,并且消耗石灰石资源,产生大量的CO2,造成二次污染。同时我国每年进口硫黄生产硫酸。文章对多种先进可靠的脱硫技术进行分析比较,将烟气中的污染物硫转变为资源硫,完全替代硫黄进口,解决石灰石法脱硫存在的问题,提出利用的途径。对于落实"调结构、转方式"科学发展具有重大意义。
A large number of desulfurization gypsum stacking caused the widely used limestone - gypsum desulfurization process, and the consumption of limestone resources, resulting in a large number of C02, cause two pollution. At the same time the annual import sulfur production of sulfuric acid in china. The desulfurization technology more advanced and reliable for the analysis and comparison of the pollutants in the flue gas, sulfur into sulfur sulfur resources, completely replace imports, to solve the existing problems of lime stone desulfurization, the way. For the implementation of＂structural adjustment, to＂ scientific development is of great significance.
