摘要
本文用疏水性聚偏氟乙烯微孔膜,进行了膜蒸馏过程的研究.结果表明,膜通量与膜两侧水蒸汽压差成正比.在一定流速范围内,膜通量随热侧、冷侧流体量增大而增大,随溶液浓度增大而减小.
The membrane distillation processes were studied with microporous PVDF hollow fiber membranes. The results showed that water flux was proportional to the vapor pressure difference in both sides of the membranes. The water flux will increase with warm water velocity or cold water velocity increasing in a certain flow range . When concentration of solution increase, the water flux will decrease.
