Method for treating chlorinated tail gas in titanium tetrachloride production process

The invention discloses a method for treating chlorinated tail gas in a titanium tetrachloride production process, which comprises the following steps: mixing a dry basis and water according to a preset proportion to prepare slurry; wherein the dry basis is a material separated from TiC-containing slag through magnetic separation in the crushing process, the TiC-containing slag is a product of TiO2-containing slag generated in the vanadium titano-magnetite smelting process in the carbonization process, and the dry basis comprises Fe, TiC, CaO and MgO; and introducing the chlorinated tail gas into the stirred slurry, absorbing chlorine-containing components in the chlorinated tail gas by using the slurry, and discharging the absorbed chlorinated tail gas up to the standard. According to the method, by-products in the crushing process of the TiC-containing slag can be effectively utilized, a large number of extra absorbents are prevented from being adopted, and the production cost is saved. 本发明公开了一种四氯化钛生产过程中氯化尾
