| 中文摘要 |
| 设计了一种新型旋转切向流聚丙烯管式膜器,实验研究了聚丙烯PA管式膜器的能耗通过建立的旋转切向流强化微滤实验装置系统,测定了聚丙烯PA管式膜器在旋转切向流和轴向流下的膜通量与能量有效利用率.实验结果表明,旋转切向流管式膜微滤比一般轴向流膜微滤的有效利用率要高得多,是一种非常有效的强化膜分离技术在实验条件下,直线切向流膜微滤和圆弧切向流膜微滤的稳态能量有效利用率比轴向流稳态能量有效利用率分别高11.185倍和14.591倍. |
| 英文摘要 |
| A new type of polypropylene tubular membrane module in rotating tangential flow was designed to experimentally study energy consuming of the polypropylene PA tubular membrane microfiltration. Through the experimental system of rotating tangential flow which was set up to enhance the microfiltration, the polypropylene PA tubular membrane fluxes and energy efficiency of rotating tangential flow and axial flow were measured under different fluid pressures. The experimental results demonstrate that rotary tangential flow tubular membrane microfiltration was a high efficiency technology of membrane separation. At test conditions, the stable energy efficiency of linear and circular tangential flow were higher than 11.185 times and 14.591 times of the stable energy applying efficiency of axial flow respectively. |
