Abstract

Abstract

Based on the physical parameters of high titanium slag and chlorine gas, the initial fluidization velocity of fluidized chlorination of high titanium slag was calculated by using the classical initial fluidization velocity formula. And the mathematical model of gas-solid two-phase flow of fluidized chlorination of high titanium slag was established by combining Euler two-fluid model. Finally, based on the numerical simulation results, the superficial gas velocity of fluidized chlorination of high titanium slag was predicted. The results show that the initial fluidization velocity obtained by Euler two-fluid model combined with Grace formula can accurately simulate the gas-solid two-phase flow characteristics of high titanium slag chlorination process. According to the volume fraction of high titanium slag particles in the fluidized chlorination bed, the velocity and pressure distribution of the cross section of the bed, the optimal superficial gas velocity for the fluidized chlorination of high titanium slag was determined to be 1.5 times the initial fluidization velocity obtained by Grace’s calculation formula.
