Abstract

Chloride process is cost effective and environmental benefit, and the TiCl4 oxidation is the most important stage in this process. The structure of the jet ring has an obviously effect on the mixing of TiCl4 and O2 in the oxidation reactor, which is the key equipment in the production of titanium pigment. In this paper, the gas mixing condition with five jet rings of different structure was simulated and analyzed by computational fluid dynamics (CFD) simulation. The radial concentration distribution of TiCl4 and the non-uniformity of the mixture with different jet rings were obtained. The results showed the structure of the jet ring has great effect on the gas mixing. The mixing condition of the jet ring with combined opening orifice is better than that of the jet ring with uniform opening orifice, which is more effective in realizing fast and uniform mixing condition of TiCl4 and O2.
