摘　　要：利用C FD软件对筛板开孔率不同的固定床离子交换塔内部流场进行模拟仿真,研究相关参数变化规律,旨在解决目前铀水冶固定床出液装置存在的工作效率低、振动和噪声较大、塔内流体紊乱、使用年限短、筛板开孔率难以选择等问题。最终分析表明:在出液装置强度满足要求的前提下,筛板开孔率与塔压反相关,与树脂转移速度正相关,当开孔率较大时,塔压较小,筛板使用寿命较长,当开孔率较小时,树脂转移稳定性高,树脂转移速率平稳,振动和噪声较小,工作效率高。The numerical simulation of flow field of the inner of the Fixed bed ion-exchange column and the research parameter variation are obtained by CFD. Then they are employed to solve the problems which exist in the filtering device in Uranium hydrometallurgy fixed bed ion-exchange tower including inefficiency, strong vibration, large noise, fluid disorders, short life, sieve opening rate is difficult to select. Final analysis shows that： if structural strength can meet the conditions, sieve opening rate is inversely related to the tower pressure, sieve opening rate is positively related to the speed of resin transfer; if the opening rate of the sieve increases, the tower pressure will decrease and the life expectancy will increase; if the opening rate of the sieve decreases, the speed of resin transfer will become steady, vibration and noise will be reduced, and work efficiency will increase.
