基于硫基循环抑制技术的危险废物焚烧炉二英排放的控制
Dioxins emission control from hazardous waste incinerator by SO2 recycling inhibition
摘要
Abstract
Sulfur acts as an effective inhibitor of dioxins formation, and such action has been proved in laboratory studies, but few studies in actual waste incinerators are reported. To control the emission of dioxins from hazardous waste incinerator (HWI) effectively, a new pilot scale system with SO2 recycling and fly ash thermal treatment from the bypass flue gas in an actual HWI (50t·d-1) was developed. An absorbent was used to realize SO2 recycling by which SO2absorption was conducted by the absorbent in the flue gas and SO2desorption was conducted in the low-temperature thermal treatment system. The capacity of SO2 accumulation and inhibition of dioxins synthesis of the system was studied, and it was found that the system could operate continuously. The system could maintain a high SO2concentration of 100 mg·m-3 after adding a certain amount of other S-compounds and reduce more than 80% of dioxins emission factor. Therefore, the SO2 recycling inhibition technology provides guidance for dioxin emission reduction during waste treatment, and the long-term stable operation of the system will play a key role in achieving low emission of dioxins, but some relevant parameters of the pilot system still need further optimization.关键词
