摘　　要：以加强传质混合为目的提出300m3赖氨酸发酵罐搅拌系统改造方案,采用计算流体力学(CFD)数值模拟方法分析了搅拌系统轴功率、流型、传质混合能力,成功指导了搅拌系统改造,在电流增大的情况下,平均单罐产量提高2.44t,平均糖酸转化率提高约1个百分点。To strengthen mass transfer and mixing for purpose,the reform scheme of stirring system in 300m3 L-lysine fermentor was proposed,CFD（Computational Fluid Dynamics） numerical simulation was used in analysing shaft power,flow pattern,mass transfer mixing ability of the stirring system,when current increased,the fermentation yield and L-lysine acid conversion rate of sugar was 2.44t and about 1% higher than the fermentor which not renovated.
