The liquid height on the tray increases with the increase of the intensity of liquid flow and the height of weir, but, fundamentally, the effect of the hole-air-speed is relatively smaller; 板上的清液层高度随液流强度的增加而增加;随着堰高的增加而增加;
The factors, such as gas and liquid rate, hole diameter and tray free areas, weir height, influencing transition from froth to spray regime on sieve trays were studied. 考察气、液负荷,孔径,开孔率以及堰高等因素对工况转变的影响。
