摘要：在外压管超滤器的管束上,设置了弓形和环形折流挡板,有效地提高了流体湍动程度。用α-淀粉酶为料液,测定了不同挡板型式时的蛋白凝胶层浓度和传质系数,并建立了传质准数方程。
With segmental and ring shaped baffles installed among the tube bundles, theturbulance extent of the external pressure tubular ultrafiltration equipment was increased effectively. With α-amylase as the feed, the concentration of the gelatinous protein layer and the mass transfer coefficient were determined.
