Abstract: During acid-making from waste desulfurization liquid,the incinerated furnace gas contains harmful impurities such as dust,fluorine and chlorine.If such impurities are not removed,they will intoxicate the acid-making catalyst.The activity and service life of acid-making catalyst will also be reduced.The quality of acid product will be influenced ubsequently.After incineration,the furnace gas purification is the basis for long-term stable operation of acid-making.Wet purification with dilute acid as scrubbing absorbent is a very effective treatment method.Therefore,circulating and renewal of scrubbing liquor volume,operating efficiency of scrubber and electric demister are the key factors influencing furnace gas purification efficiency.
Key words: Waste desulfurization liquid, Acid-making, Harmful impurities, Furnace gas , purification
