Abstract

A novel type of Venturi ejector reactor was developed and used in the pilot plant to overcome the insufficiency of chemical reaction in the stirred-tank reactor in yellow phosphorus purification system based on the process requirement. The effects of four nozzles with different diameter (6 mm, 8 mm, 10 mm and 12 mm respectively) and the performances of the Venturi ejector reactor with different operating pressure were investigated by FLUENT with Realizable k-ε turbulent model and Eulerian two-phase model. Results show that the experimental data in the pilot plant test are quite similar to the data comes from numerical simulation with the same operating condition. The numerical simulation results show that pressure ratio and work efficiency are getting higher with the increase of nozzle diameter. The value of pressure drop is getting higher and the dispersive mixing effect is better with the decrease of nozzle diameter.
