    • PURPOSE: A method of treating a by-product gas from copper smelting is provided to produce sulfuric acid and hydrogen at high speed by removing the air from refined sulfur dioxide gas and resupplying non-reacted sulfur dioxide to an electrochemical cell. CONSTITUTION: A method of treating a by-product gas from copper smelting comprises the steps of: obtaining by-product gas containing sulfur dioxide from a copper mat manufacturing process, obtaining refined sulfur dioxide by successively performing washing, dust collection, and drying, obtaining high-purity sulfur dioxide by separating the sulfur dioxide from the refined sulfur dioxide, and obtaining sulfuric acid and hydrogen by injecting sulfur dioxide to the anode of an electrochemical cell(60) with a cation exchanging film and water to the cathode of the electrochemical cell.
    • 目的:通过从精炼的二氧化硫气体中除去空气并将未反应的二氧化硫再供给电化学电池,提供一种处理来自铜冶炼的副产物气体高速生产硫酸和氢气的方法。 构成:从铜冶炼处理副产物气体的方法包括以下步骤:从铜垫制造工艺中获得含二氧化硫的副产物,通过连续进行洗涤,粉尘收集和干燥获得精制二氧化硫,获得 通过将二氧化硫从精制二氧化硫中分离出来,通过将二氧化硫注射到具有阳离子交换膜和水的电化学电池(60)的阳极上的二氧化硫到电化学电池的阴极来获得高纯度二氧化硫 。
