White mud-gypsum method wet flue gas desulfurization device

The invention provides a white mud-gypsum method wet flue gas desulfurization device. The white mud-gypsum method wet flue gas desulfurization device comprises a limestone powder bin, a slurry pot, absorption towers and a white mud slurrying pool; the limestone powder bin is connected with the slurry pot through limestone powder feeding pipelines; the slurry pot is connected with the absorption towers through slurry pot discharging pipelines; the white mud slurrying pool is connected with the slurry pot through white mud slurrying pool discharging pipelines and the absorption towers; filter screens are arranged in the middle of the interior of the white mud slurrying pool, and the filter screens divide the white mud slurrying pool into a feeding bin and a discharging bin; the feeding bin and the discharging bin are each connected with a stirring device; the discharging bin is connected with the white mud slurrying pool discharging pipelines, and the white mud slurrying pool discharging pipelines are each provided with a white mud slurry discharge pump. The white mud-gypsum method wet flue gas desulfurization device is simple in structure, good in white mud flowability and capable of effectively utilizing the white mud to conduct the wet desulphurization technology, and the effect of two-way control over the white mud and sulfur dioxide is achieved.
