Vanadium removal method for titanium tetrachloride in fluidizing chlorination system

The invention discloses a vanadium removal method for titanium tetrachloride in a fluidizing chlorination system, comprising the following steps of: conveying the carbon-containing slurry from a carbon-containing slurry tank to a crude titanium tetrachloride processor; mixing the carbon-containing slurry with a crude titanium tetrachloride liquid to obtain mixed slurry; returning the mixed slurryinto a quenching pipe; mixing the mixed slurry atomized by a atomizing nozzle with gas-phase titanium tetrachloride; reacting to generate vanadium oxydichloride; enabling the vanadium oxydichloride toenter a dust collector along with gas-phase titanium tetrachloride; collecting and treating vanadyl dichloride by the dust collector; enabling the gas-phase titanium tetrachloride in the dust collector to enter a titanium tetrachloride leaching tower from a gas outlet of the dust collector to be leached, feeding the obtained titanium tetrachloride liquid into a titanium tetrachloride storage tank, enabling the titanium te
