| titleOfInvention | Method for treatment of chlorinated waste molten salt generated in TiCl4 production process |
| abstract | Relating to comprehensive treatment and utilization methods of chlorinated molten salts, the invention discloses a method for treatment of a chlorinated waste molten salt generated in a TiCl4 production process. The method consists of: discharging a waste molten salt generated during TiCl4 production from a furnace, cooling the salt, and subjecting it to layered crushing, leaving the chlorinated waste molten salt to undergo a water dissolution treatment to prepare an NaCl-containing solution, separating residue and a chloride to conduct treatment, removing iron, manganese and chromium, carrying out filtration to obtain residue and a supernatant, adding an alkali solution into the supernatant to separate a precipitate, and conducting washing to remove Cl<-> so as to obtain a magnesium product and a supernatant, treating the magnesium product to prepare a magnesium hydroxide flame retardant or active magnesium oxide, then adding sodium carbonate into the supernatant to obtain calcium carbonate micro-powder and a high purity NaCl solution, and treating the calcium carbonate micro-powder and the NaCl solution respectively, thus realizing comprehensive utilization of the waste molten salt. The method disclosed in the invention solves the waste molten salt and Cl<-> containing wastewater environmental pollution problem plaguing the molten salt chlorination preparation method of TiCl4 for a long term. |
