Solution, separates out the metallic aluminium of liquid on negative electrode, is produced with CO on anode2Based on anodic gas.Simultaneously because anode carbon block
In contain S elements, therefore also contain SO in addition to containing with hydrogen fluoride, fluoride, dust in electrolytic aluminum smoke2.Former electrolytic aluminium
Technique uses anode carbon block S constituent contents low, SO in electrolytic aluminum smoke2Concentration it is relatively low, so the electricity set up before
Solution aluminium flue gas purification system is equipped without desulfurization.But sulfur content is increasingly in the anode carbon block that is used by electrolytic aluminium at present
Height, causes SO in electrolytic aluminum smoke2Concentration also increase.According to SO in calculating current electrolysis aluminium flue gas2Concentration be generally
200-300mg/Nm3。
According to《Aluminum i ndustry pollutant emission standard》（GB25465-2010）And promulgate for 2014《Aluminum i ndustry pollutant is arranged
Put standard》Amendment, it is desirable in key area by SO2Concentration control in 100 mg/Nm3Below, it is therefore desirable to electrolytic aluminium cigarette
Gas carries out desulfurization process.
Electrolytic aluminum smoke have exhaust gas volumn it is big, containing sulphur concentration it is relatively low the characteristics of, therefore use Gypsum Wet
Desulphurization system floor space is big during sulfur removal technology, system operation whole efficiency is relatively low, operating cost is high.External electrolytic aluminium factory is general
Build by the sea, therefore generally using the technique of sea water desulfuration.But domestic electrolytic aluminium factory is due to electricity price factor, typically will electrolysis
Aluminium manufacturer is built in the relatively low inland of grid electricity fee cost, does not possess the condition of sea water desulfuration.Therefore need for China's aluminum electrolysis industry
Actual conditions, develop new electrolytic aluminum smoke sulfur method and equipment.
