摘　　要：针对国内某铜冶炼厂的实际生产情况,分析比较了石灰石-石膏法、双氧水法、再生胺吸收解吸法三种脱硫工艺的原理、优缺点及生产运营成本。结果表明,双氧水法脱硫流程短投资低,具有可回收SO、水耗低、占地少、无废水和废渣排放等优点,运行成本略高于石灰石-石膏法,低于再生胺吸收解吸法。经综合比较,对该厂环集烟气脱硫的改造推荐采用双氧水法脱硫工艺。同时,提出了双氧水法环集脱硫改造的方案。The principle,advantages and disadvantages and operation cost of three desulfurization processes,limestone-gypsum method,hydrogen peroxide method and regenerated amine absorption-desorption method,were analyzed and compared according to the actual production of a copper smelter in China.The comparison results show that the hydrogen peroxide desulfurization process has several advantages:short process,low investment,recyclable SO,low water consumption,less land occupation,no wastewater nor waste residue discharge,and the balanced operating cost-slightly is higher than that of the limestone-gypsum method and is lower than that of the regenerated amine absorption-desorption method.After comprehensive comparison,the hydrogen peroxide method was recommended for the retrofit of the fugitive off-gas desulfurization system in this plant.And a scheme of the retrofit following the hydrogen peroxide method was put forward.
