烧结烟气氨法脱硫与氧化脱硝复合技术

The Combined Desulfurization and Denitrification Technology of Sintering Flue Gas

根据烧结机烟气的特点,结合环保政策的要求,在新型氨法脱硫的基础上,复合一种氧化脱硝技术,对烟气中的SO2和NOx进行联合脱除,并对其技术要点进行了简要分析。结合工业试验的效果进行分析,结果表明:认为氨法脱硫与氧化脱硝复合技术在钢铁行业烧结烟气协同治理方面具有很高的推广价值。

Basing on the physical and chemical characteristics of sintering flue gas and following the policies of environmental protection,we have researched the removing effect of SO_2 and NO_x with the technology of combining the fresh ammonia flue gas desulphurization and oxidation denitration. The abstract of this combining technology is also described simply. The results of the industrial experiment show that it is worth to promote the technology of combining ammonia desulphurization with oxidation denitrificationat removing SO_2 and NO_x together of sintering flue gas in steel industry.
