    A modified surface film renewal model based on a picture of the mechanism of the mass transfer between the gas and liquid phases is proposed.This model explains why the mass transfer rate at the beginning is faster,but will approach steady state after a certain period. A graphical presentation for calculations based on the methmatical model derived is suggested. Data for several mass transfer processes taken from the literature were examined and their respective surface renewal...

    A modified surface film renewal model based on a picture of the mechanism of the mass transfer between the gas and liquid phases is proposed.This model explains why the mass transfer rate at the beginning is faster,but will approach steady state after a certain period. A graphical presentation for calculations based on the methmatical model derived is suggested. Data for several mass transfer processes taken from the literature were examined and their respective surface renewal frequencies, 5, were calculated with results more practical than those from Danckwerts model.

    Magnitude and direction of gas pressure gradient, i. e. pressure gradient field in the blast furnace has been proved theoretically and experimentally to be the fundamental aerodynamic factor for the descent or movement of granular solid beds and liquid droplets of iron and slag. Mechanism or mechanics of hanging in the furnace has also been analyzed.Importance of pressure gradient field for describing gas stream field in it was shown. On this basis we can further investigate the heat transfer and mass transfer processes mathematically and finally find out a reasonable model for the whole blast furnace process. Some very useful instructions for blast furnace operation were derived from this investigation.

    煤气流影响高炉炉料及渣铁运动的基本力学因素不是热风(煤气)压强的绝对值或总压差,而是压强梯度矢量场的性质。压强梯度是作用于炉料及渣铁的一种体积力,本文通过理论推导和试验对此加以论证;并证明局部压强梯度超过炉料容积重量是炉内发生悬料的力学条件;对成渣带、风口循环区附近和渣铁滴落带的液相行为作了分析。此外,压强梯度是描述流速场和压强场,建立高炉散料流体力学模型的重要杠杆,而流体力学模型又是传热和传质模型的基础,从本研究得出指导生产的重要结论。

    The boundary of steady state zones was investigated from the viewpoint of equilibrum theory ard rate theory when the rare earths were separated with NTA by means of high pressure ion exchange chromatography. It has been ascertained that the mass-transfer process is mainly controlled by film diffusion, and that longitudinal diffusion can actually be neglected under the condition of high flow rate; and HETP is not affected by retaining or concentration of displacingion.

    本文使用平衡塔板理论和速率理论,研究了NTA作螯合剂排代分离稀土时的界面状态。证明了在我们选定的高流速排代实验条件下,膜扩散是传质过程的主控阶段,纵向扩散实际上可以忽略。阻滞离子性质和排代离子浓度不影响HETP。排代剂线性流速从2.5厘米/分增加到25厘米/分,HETP按直线关系增加,其斜率和截距与离子性质有关。线性流速增加一个数量级时,HETP只增大一倍,显示了NTA的优良动力学特性。
