Dry plate pressure drop of conventional sieve tray and tapered sieve tray were measured with air in a φ500 mm transparent tower made of polymethacrylate.

在直径500 mm的有机玻璃塔内,以空气为物系,对普通筛孔塔板和锥形筛孔塔板的干板压降进行测定,根据Hughmark-O'Connell关联式计算得到孔流系数。

Two different types of orifices were opened on wall of exit weir of both sieve tray and fixed valve tray for comparison.

针对固定阀塔板和筛孔塔板,在出口堰上开倒梯形和条形两种型式的分流孔,对从堰上分流孔分流出去的液量作了实验研究,得到了分流液量随气、液流量变化的规律。

Possibility of the unit expansion to 56 000 b/d has been discussed together with the optimum design criterion of sieve tray.

深入探讨了对筛孔塔板的优化设计判据,指出应根据塔板的作用来区别考虑塔板的适宜操作范围。

Screen length,incline angle,and screen-aperture are the most important screen pa-rameters,which directly relate to the capacity and efficiency of the screen.

筛面长度、倾角和筛孔孔径是最重要的筛面参数,与筛分机的处理能力和筛分效率有着直接的关系。
