doi:10.16085/j.issn.1000-6613.2021-1650

Abstract

Abstract:

The sintering process is an important step in the production chain of the iron and steel industry but it is also the main emission source of sulfur dioxide, nitrogen oxide, and dioxin in the atmosphere. With desulphurization technology becoming mature, the reduction of nitrogen oxides and dioxins has become the top priority of emission reduction for sintering flue gas. In this paper, the new regulations and relevant standards for emission reduction of multiple pollutants in sintering flue gas are introduced. The latest research progress and industrial application status of nitrogen oxides and dioxins reduction in sintering process are reviewed from the three aspects of source control, process reduction and end treatment. Moreover, it is proposed that adopting the whole process multi-technology coupling mode is the development direction to realize the multi-pollutant emission reduction of sintering flue gas at low cost. Under the new development requirement of "carbon emission reduction" in the iron and steel industry, the research challenge of low-temperature denitrification/dioxin catalysts for sintering flue gas is summarized. Finally, this paper prospects the future research directions of improving the water and sulfur resistance for the low-temperature catalysts.

Key words: sinter flue gas, nitrogen oxides, dioxins, emission reduction, low-temperature catalysts

摘要：

烧结工序是钢铁工业生产链的重要环节，同时也是大气中二氧化硫（SO₂）、氮氧化物（NO _x ）和二英的主要排放源。随着烧结烟气脱硫技术日趋成熟，氮氧化物和二英的减排成为烟气污染物减排的重中之重。本文介绍了钢铁工业烧结烟气超低排放的新法规和相关标准，并从源头控制、过程减排和末端治理三个方面综述了国内外关于烧结烟气中NO _x 和二英减排的最新研究进展及相关技术工业应用现状，提出了采用全流程多技术耦合方式是实现烧结烟气多污染物低成本减排的发展方向。结合钢铁工业“碳减排”新发展要求，指出烧结烟气低温脱硝/二英催化剂的研究挑战，并对其抗水、抗硫性能提升研究进行了展望。
