Governance Technology and Method of Ultra-low Emission of Flue Gas with High SO2 Concentration
Taking the high SO2 concentration flue gas of graphitizing furnace as an example,the lime-gypsum desulphurization process is adopted,new technologies and methods,such as double-tower and double-cycle,low flue gas flow rate,high liquid-gas ratio,efficiency-enhancing tray and high efficiency tube-bundle mist eliminator,are optimized to realize ultra-low flue gas emission,it provides a reliable reference for ultra-low treatment of flue gas with high SO2 concentration in other industries,and has an important reference significance.
