Abstract

The invention relates to an organic matter vanadium removal mud solid-liquid separation device and a method for carrying out organic matter vanadium removal mud solid-liquid separation by adopting the device and belong to the field of mixed metallurgy. The method comprises the following steps: inputting organic matter vanadium removal mud into a drying oven through a mud inlet, enabling the organic matter vanadium removal mud to flow through a filtering element in a filter unit, and realizing separation of organic matter vanadium removal residue and titanium tetrachloride in the mud; after filtration, introducing heated inert gas, so that titanium tetrachloride in a filter cake on the filter unit is evaporated, the evaporated titanium tetrachloride gas is recycled by a condenser connected with a condenser connector, so that titanium tetrachloride is obtained; and finally blowing out the dried organic matter vanadium removal residue from a hot gas outlet by virtue of atmospheric flow, and collecting. The device and method which are provided by the invention have the advantages that solid-liquid separation efficiency is more than 99%, and recovery ratio of TiCl4 in the mud is more than 98%; and no chlorinated tailing is doped, so that the separated organic matter vanadium removal residue also can be used for vanadium extraction production, and recycling is realized.

Description

technical field [0001] The invention relates to a solid-liquid separation device for an organic vanadium-removing mud and a method for solid-liquid separation of an organic vanadium-removing mud by using the device, belonging to the field of mixed metallurgy. Background technique [0002] The refined tailings of titanium tetrachloride is the slag produced by using aluminum powder to remove vanadium from crude titanium tetrachloride produced by the chlorination method, and is one of the typical solid wastes in the production process of TiCl4. During the chlorination process, the V in the titanium slag 2 o 5 Chlorinated to generate VOCl 3 . At present, the more mature vanadium removal processes are organic vanadium removal process and aluminum powder vanadium removal process, especially for chloride titanium dioxide, organic vanadium removal process has become the absolute mainstream vanadium removal process due to its advantages of large production capacity and low cost. ...
