The invention provides a method and a
system for recycling
vanadium-containing mud generated in a
vanadium removal process of crude
titanium tetrachloride. The
vanadium-containing mud contains
titanium tetrachloride liquid and VOCl2
solid. The method comprises the steps of adding the vanadium-containing mud into a
molten salt furnace, evaporating, and collecting
titanium tetrachloride in the vanadium-containing mud; introducing
chlorine into the vanadium-containing mud to ensure that
chlorine is reacted with VOCl2 in the vanadium-containing mud, and obtaining
mixed gas containing VOCl3 gas and
chlorine; condensing the
mixed gas to obtain VOCl3 liquid and chlorine, wherein
molten salt is filled in the
molten salt furnace, and the temperature of the molten salt furnace is kept at 600-750 DEG C. The recycling
system is used for implementing the method, and comprises the molten salt furnace, an air supply
pipe, a TiCl4 gas collecting unit and a condenser. The recycling method and recycling
system, provided by the invention, are used for realizing one-time
recovery of valuable elements namely titanium and vanadium in the vanadium-containing mud, and are high in yield of vanadium and titanium, and high in purity of obtained products.
