摘要
Abstract
Based on the function provided by Fluent, the critical suspension impeller speed, Njg, in a phosphoric acid reaction tank was simulated. The investigation was carried out in a fully baffled, flat bottom,cylindrical vessel with 500 mm diameter,equipped with PBT impeller. The phosphogypsum of 4. 65% was chosen as the dispersed phase. The original criterion was used to determine Njg from the numerical results,and the error of simulation is acceptable to the industry standard. Solid concentration distribution and the velocity distribution of solid and liquid were predicted. The performance of solid suspension under the different agitation speeds was also studied, the critical suspension impeller speed was obtained.关键词
