摘　　要：针对冶炼烟气量和SO_(2)浓度增加导致的制酸系统压损增加、热平衡难以维持的问题,在现有系统的基础上进行优化改造,通过转化热能多级回收、多通道冷热换热器应用、吸收塔分酸器和填料层结构改进、吸收酸阳极保护换热器工艺改进等措施,实现了制酸系统技术优化与产能提升,与前端冶金炉窑匹配化生产。In response to the challenges of increased pressure loss and the difficulty of maintaining thermal balance in the acid production system caused by the rise in smelting flue gas volume and SO_(2) concentration,optimization and transformation efforts were implemented based on the existing system.Measures such as multi-stage recovery of converted heat energy,the application of multi-channel cold and heat exchangers,enhancements to the structure of the absorption tower acid separator and packing layer,and improvements to the process of the absorption acid anode protection heat exchangers were undertaken.These initiatives successfully optimized the technology of the acid production system and enhanced its capacity,aligning it with the production requirements of frontend metallurgical furnaces.
