    Calculation of Plated UF DeviceUnder Instable Condition

      摘要
    • 摘要: 在脉冲进料非稳态工况下,对板式超滤器中的表面剪切力进行了研究,并建立了相应的数学模型.研究结果表明:膜表面沉积物厚度在很大程度上取决于膜通道中流体的流速,振幅、频率等物理量.在Re<200时脉动进料的非稳态剪切力可十分有效地去除膜表面上的沉积物垢层并提高膜通量.

       

      Abstract: Under instable condition on pulsation feed, the surface shearing stress along membrane passage of the plate-frame UF device was studied. The result shows experiments that to a great extent the, thickness of deposit cover on membrane surface dependes on the fluid flowing velocity in. membrane channel, the amplitude and frequency. When Re<200, the instable surface shearing stress can efficiently eliminate foul cover deposited on membrane surface and thus increase membrane flux.
