摘要
采用搅拌功率测定与氧传递性能试验的方法,对Parabola型搅拌桨叶的混合性能进行了研究。通过与Ruston桨的对比表明,P型桨具有如下优点:1通气搅拌功率不降低,搅拌剪切力小;2在一定功率输入和通气量下,容积传氧系数较高。因此,P型桨应用于生物好氧反应的情况是非常有效的。
The mixing characteristics of Parabola turbine have been studied by experiment.Compared with Ruston turbine,Parabola turbine has many advantages:① stirring energy is not reduced,while gas is through in; shearing stress is little;② on constant energy and gas velocity,KLa is higher.Therefore,Parabola turbine must be very efficient in biochemical engineering.
