Experimental device for crystallization of ammonium sulfate mother liquor doped with calcium sulfate

Abstract

The utility model discloses an experimental device for crystallization of ammonium sulfate mother liquor doped with calcium sulfate, which relates to the technical field of preparation of ammonium sulfate crystals and comprises a filter device, a reaction device connected with the filter device, a constant-temperature water bath device connected with the reaction device and an ammonium sulfate mother liquor crystallization device connected with a discharge port of the reaction device. The suction filtration device is connected with the ammonium sulfate mother liquor crystallization device, the drying device is connected with the suction filtration device, and the screening device is connected with the drying device. According to the utility model, the evaporative crystallization principle is adopted, and the morphology, size or purity of ammonium sulfate crystals can be improved by adding different amounts of calcium sulfate through the feeding device, so that an ammonium sulfate product which better meets the requirement is obtained; and meanwhile, the method is suitable for crystallization of ammonium sulfate mother liquor generated by ammonia desulfurization for different industrial flue gas treatment.
