摘要
某有色冶炼企业现有环集烟气脱硫装置一套,处理熔炼环集烟气等,采用石灰石-石膏法脱硫工艺,副产石膏。该脱硫装置运行良好,脱硫效率较高,开工率较高,脱硫尾气能够达标排放,存在的问题是石膏渣去向,废水量偏大。本次铜冶炼工艺改造后,吹炼环集烟气并入冶炼工艺烟气进烟气制酸系统,环集烟气脱硫系统处理熔炼环集烟气、沉降电炉环集烟气、阳极炉环集烟气和阳极炉工艺烟气。脱硫效率≥80%。脱硫尾气排放符合《铜、镍、钴工业污染物排放标准》(GB25467-2010)修改单中规定的特别排放限值标准,满足排放要求,不仅可以解决废气的环境污染问题,而且每年可为公司节省一定的废水处理成本。
A non-ferrous smelting enterprise has a set of flue gas desulphurization device for treating smelting flue gas.The desulphurization process adopts limestone-gypsum method,the by-product is gypsum.The desulphurization unit runs well with high desulphurization efficiency,the operation rate is high,the desulphurization tail gas can meet the emission standard.The existing problem is how to deal with the gypsum residue and large quantity of wastewater.After the copper smelting process reform,the converting environmental flue collection system gathers the flue gas into the acid making system.The flue gas desulphurization system is used to treat the fugitive gas from melting,electric furnace,anode furnace and flue gas from anode furnace process.Desulphurization efficiency is≥80%.The desulphurization tail gas emission conforms to the special emission limit standards stipulated in the revised"Copper,nickel and cobalt industrial pollutant emission standard"(GB25467-2010),and meets the emission requirements.It can not only solve the environmental pollution problem of waste gas,but also save the cost of waste water treatment for the enterprise every year.
