The invention discloses a method and equipment for separating titanium tetrachloride from vanadium-containing mud, which belong to the technical field of treating titanium tetrachloride vanadium-containing mud. The method and the equipment solve the problems that the heat transfer area is small in the prior method for treating the titanium tetrachloride vanadium-containing mud by using a heat source to heat the outer wall of a distillation kettle, dry slag formed nearby the heat transfer wall at the middle and final stages of distillation increases thermal resistance so as to cause difficult separation of the titanium tetrachloride in the vanadium-containing mud at the center part far from the heat transfer wall, and the utilization rate of heat energy in the distillation process is low. A graphite heat exchanger is soaked into the titanium tetrachloride vanadium-containing mud to absorb microwave, and the heat produced when the graphite heat exchanger absorbs the microwave is evenly transferred to the titanium tetrachloride vanadium-containing mud through the graphite heat exchanger so as to achieve the aim of efficiently separating the titanium tetrachloride from the vanadium-containing mud. The method and the equipment have the characteristics of high utilization rate of electrical energy and good separating effect of the titanium tetrachloride.
Description
Background technique [0001] In the method of separating titanium tetrachloride from vanadium-containing mud, the distillation method using traditional heat source heating is limited to the wall of the distillation tank, and the heat transfer area is small. In the middle and late stages of the vanadium-containing mud evaporation process, due to Dry slag appears preferentially near the heat transfer wall, resulting in increased thermal resistance, making it difficult for titanium tetrachloride in the vanadium-containing mud far away from the heat transfer wall to be evaporated. Therefore, this method has the limitations of high energy consumption and poor separation effect of titanium tetrachloride. The method of spraying the vanadium-containing mud into the chlorination furnace, and the method of spraying the vanadium-containing mud into the first dust collection condenser announced by CN1199863C, because of the problem of vanadium in the chlorination-refining system internal c...
