Problems solved by technology

[0003] At present, due to the different and imperfect refining processes, the mixing effect of crude titanium tetrachloride and mineral oil in the production process is not good, resulting in poor vanadium removal effect of crude titanium tetrachloride and refined tetrachloride after vanadium removal. The quality of titanium chloride fluctuates greatly, frequent pipeline and equipment blockages cause discontinuous production, frequent equipment and pipeline maintenance, resulting in waste of industrial raw materials and mat

Abstract

The invention discloses a system and a method for processing coarse titanium tetrachloride. The system comprises a mixing tank, an evaporator, a buffering tank, a vanadium slag pump and a vanadium slag recovering device, wherein the mixing tank is provided with a coarse titanium tetrachloride inlet, an organic matter inlet and a mixture outlet; a stirrer is arranged in the mixing tank; the evaporator is provided with a mixture inlet, a steam inlet, a fine titanium tetrachloride gas outlet and a vanadium slag outlet; another stirrer is arranged in the evaporator; the buffering tank is provided with a vanadium slag inlet and a vanadium slag discharging port; the vanadium slag pump is connected with the vanadium slag discharging port; and the vanadium slag recovering device is connected with the vanadium slag pump. With the adoption of the system, the average blocking times of a vanadium slag pipeline are reduced to be once a month; the perforating times of the vanadium slag pump are reduced to be once every three months; in addition, the yield of obtained fine titanium tetrachloride is beyond 95%; and compared with the prior art, the yield of fine titanium tetrachloride is increased by more than 18-35%.

Description

Technical field [0001] The present invention belongs to the field of chemical industry. Specifically, the present invention relates to a system and method for processing crude titanium tetrachloride. Background technique [0002] At present, in the production process of titanium dioxide produced by the chloride method, the crude titanium tetrachloride produced needs to be refined, and the refining is mainly to remove the vanadium in the crude titanium tetrachloride. The existing refining processes mainly include the removal of vanadium from copper wire, the removal of vanadium from aluminum powder, and the removal of vanadium from organic matter. The specific implementation process is selected according to economic benefits and needs. For the production of titanium dioxide by the chlorination method, organic matter is mainly used to remove vanadium, and the selected organic matter is oil. Through the reducibility of the oil, the vanadium in the crude titanium tetrachloride genera...
