A method for treating halogen compound aqueous solution, acidic solution, or acidic gas and an apparatus for treating them

摘要

halide solution, to detoxifying the acidic aqueous solution or an acidic gas, high efficiency and processing methods to provide a device for the purpose. To this end the present invention to calcium chloride (Ca (OH) ₂ ) or calcium carbonate (CaCO ₃ ) dissolving tank 30 for storing the bulk material or the particulate material consisting of (HCl) is introduced an aqueous solution containing, by reacting the aqueous solution from the dissolving tank 30 is converted to an aqueous solution containing hydrogen chloride (HCl) salt (CaCl ₂ ) of an aqueous solution containing, The transformed salt (CaCl ₂ ) in the settling tank 20 to be supplied to the aqueous solution containing, aqueous solution of a halogen compound, a halogen compound or an acidic aqueous solution by introducing the acid gas, an acidic aqueous solution or the acid gases I is characterized in that the extract precipitated as insoluble calcium compound.
