Abstract

The paper briefly introduces the dearsenifying process of yellow phosphorus and the basic structure, working principle, advantages and application of cyclone separator used in P-H₂O₂ treatment, emphasizes on the internal flow field in the phase separator. However, the experimental method can not fully reveal the nature of the flow field. In this paper, a CFD modeling methodology is established to simulate the phase separator, making use of the Gambit software to complete the geometric modeling,hybrid grid division and boundary condition assignment. Through selecting the Reynolds stress model (RSM) of Fluent application, computational fluid dynamics (CFD) analysis is performed on the centrifugal cyclone, and inner flow field,velocity field,pressure field and the volume fraction changing tendency of yellow phosphorus in the equipment can be obtained. A comparison between the simulated separating efficiency and tested result was carried on. The results can provide a reliable basis for the industrial scale-up design of the P-H₂O₂ separator.
