摘　　要：介绍了韶冶一硫酸净化工序技术改造和运行情况.改造采用了三塔(空塔、动力波、填料塔)、两电和冷凝器间接冷却烟气移热流程.改造后生产工艺稳定,净化效率大大提高.The technical modifications to the purification process in sulphurie-aeid making at Shaoguan Smelting Works, and the operating conditions of the equiprnent after the modification are described in the paper. The modifications were conducted by adopting three “towers”, namely an empty column, a dynamic wave washer, and a packed column, using a two-stage electrical demister, and employing a two-stage indirect cooler. The purification process operated steadily and the purification efficiency improved markedly after the modification.
