Background
When the fire coal flue gas is used for removing nitrogen oxides and sulfides, the flue gas containing SO2 after dust removal is introduced into lime-limestone to be ground into slurry, SO that SO2 is removed. The lime slurry reacts with SO2 to generate calcium sulfate and calcium sulfite, and the calcium sulfite is oxidized and converted into calcium sulfate to obtain an industrial byproduct gypsum, namely desulfurized gypsum. The content of impurities and chloride ions in the desulfurized gypsum produced in the process is high.
Too high content of chloride ion will aggravate corrosion of metal in the absorption tower and shorten the service life of the equipment. The use efficiency of the slurry of the absorption tower is reduced, and the consumption of the desulfurizer and the power consumption of equipment are increased. The efflorescence phenomenon occurs in the process of preparing gypsum blocks and gypsum boards, thereby affecting the quality of the gypsum.
