Abstract：In response to the desulfurization requirements of the electrolytic aluminum industry,a full-time super-large electrolytic aluminum flue gas desulfurization technology is developed.Taking typical projects as the research object,this technology is introduced from aspects such as full-time operation,optimization of the core process of super-large desulfurization,and the structure of the super-large diameter tower body.The results show that compared with the traditional technology,the adoption of this technology saves 8 million yuan in construction investment(a reduction of 8.4%),reduces the annual operating cost by 2.383 million yuan(a reduction of 11.4%),reduces the labor quota by 20 people,and reduces the annual emission of sulfur dioxide by 283.8 t(a reduction of 31%).This technology requires less investment,has low operating costs and obvious environmental benefits,and is suitable for new construction and expansion and renovation projects.
