Using wet cleaning process, containing fluorine gas form aluminum electrolysis was absorbed by calcium sulfate solution. Main influence factors of purification process of fluoride flue gas flow rate, gas liquid ratio and the concentration of absorbent were studied. The experimental results showed that when the fluoride gas flow was 800 L/h, gas liquid ratio was 5:1, absorbent concentration was 1. 53 g/L, fluoride in flue gas hydrogen fluoride absorption rate can reach 99. 22%, which was conformed to the state comprehensive atmospheric pollutant discharge standards.
