不同旋流高度的旋流塔板性能实验研究

Experimental Study on the Performance of Swirl Trays with Different Swirl Heights

基于空气-水物系,在内径为30 mm、高为1650 mm的塔内,研究了旋流分离高度分别为258、288和318 mm 3种旋流塔板的流体力学性能。实验表明:干板压降与板孔动能因子F呈二次曲线关系,且旋流高度在一定范围内对干板压降影响较小;液相流量对于旋流塔板湿板压降影响有限,而气相流量对旋流塔板湿板特性的影响表现为旋流高度越小,临界气相流量越小,同时越容易达到饱和气相流量;旋流高度对雾沫夹带和漏液的影响很小,3种塔板出现雾沫夹带时气量均分布于95 m^3/h左右,3种塔板出现漏液时气相流量均分布于45 m^3/h左右。

Based on the air-water system,the hydrodynamic properties of three types of swirling tower plates with separation height of 258,288 and 318 mm were studied in the column tower with an inner diameter of 30 mm and a height of 1650 mm.The experiment shows that the pressure drop of dry plate has a conic relationship with plate kinetic energy factor F,and the rotation height has little influence on the pressure drop of dry plate in a certain range.The influence of liquid flow on the pressure drop of the wet plate of the swirling tower plate is limited,and the influence of the gas flow on the characteristics of the wet plate of the swirling tower plate is as follows:the smaller the height of the rotation,the smaller the critical gas flow,and the easier it is to reach the saturated gas flow.The influence of swirling height on foaming belt and leakage fluid is very small.The gas volume of foaming belt in 3 kinds of towers is distributed at about 95 m^3/h,and the gas flow in 3 kinds of towers is distributed at 45 m^3/h.
