Abstract

Abstract

In order to realize the efficient recovery and utilization of titanium tetrachloride and valuable metals in the slurry, a vacuum rotary evaporation experiment and vacuum stirring evaporation system for titanium tetrachloride slurry were designed. This paper, used the waste heat steam to heat the titanium tetrachloride, the screw vacuum pump set provided a higher vacuum degree, and the stirring blade stirred the slurry. The moisture content of the obtained dry titanium tetrachloride powder was less than 1%, and the recovery rate of titanium tetrachloride was 99%, effectively solving the complex treatment problems of titanium tetrachloride slurry and difficult recovery of valuable metals in the slurry. The system was environmentally friendly, with high operation efficiency and automation, and was suitable for large-scale titanium tetrachloride production.
