Research progress of persistent organic pollutants formation mechanism in iron ore sintering process
摘要
Abstract
Regarding the environmental protection in iron and steel industry,the problem of persistent organic pollutants formation in iron ore sintering process has become an important research topic. This paper introduces characteristics of PCDD/Fs,related parameters of sintering process,the emission levels and features of PCDD/Fs in sintering process. It is found that the key to control the PCDD/Fs pollutants lies in sintering flue. Then,the formation mechanism and influencing factors of PCDD/Fs are discussed,and it suggests that the pollutants of PCDD/Fs mostly generated in the sintering bed inside. Analysis and comparison of the synthesis conditions,such as temperature,carbon source, chlorine source,oxygen,catalyst,etc.,are carried out. Several important conclusions are drawn as theoretical basis for the researches on persistent organic pollutants in iron sintering process. Furthermore,current PCDD/Fs pollutants source-reduction techniques are summarized and compared. It is implied that pollutants-control mechanism of inhibitors in sintering process under complex conditions and their influences on sinter properties still need to be further studied. PCDD/Fs formation inhibition technology in the sintering process will become an important research direction.关键词
