The hydrodynamics of perform trays were studied using air-water system in a column with a 1200 x 400mm rectangular cross section to determine the effect of tray geometrical parameters and operating conditions on the pressure drop, entrainment and weeping. Geometrical variables and operating range were mainly as follows: slot widths, 3, 3.5, 4, 4.5 and 4.7mm; tray free areas, 9.9, 12.3, 14.9 and 15.4%; deflector widths, 150, 200, 250 and 300mm; tray spa-cings, 400, 500, 600, 700 and 800mm; liquid flow rates per...

Geometrical variables and operating range were mainly as follows: slot widths, 3, 3.5, 4, 4.5 and 4.7mm; tray free areas, 9.9, 12.3, 14.9 and 15.4%; deflector widths, 150, 200, 250 and 300mm; tray spa-cings, 400, 500, 600, 700 and 800mm; liquid flow rates per unit weir length, 20, 30, 45 and 60m3/m.h; and superficial gas velocities, 0.60 to 2.8m/s. Experimental data were correlated and correlations were presented for calculating the pressure drop, entrainment and liquid weeping. Furthermore, based on the experimental results for the entrainment and weeping from the tray,the expressions were given also to predict the upper limiting hole velocity at which the entrainment from the tray is 10%, the lower limiting hole velocity at which the liquid weeping from the tray is 5%. In addition, the effect of inlet weir on the weeping were tested and a simiempirical model was derived for the inlet weir design.

木文以空气-水系统在1200×400mm矩形装置内对网孔塔板的流体力学进行了试验研究。试验所采用的塔板参数和操作条件为:塔板开口宽度为3、3.5、4、4.5及4.7mm;塔板开孔率为9.9、12.3、13.2、14.9及15.4%; 挡沫板宽度为150、200、250、300mm;板间距为400、500、600、700及800mm;液流强度为20、30、45、60m~3/m·h;气体空塔速度为0.60—2.8m/s。测定了各有关参数对塔板压降、雾沫夹带和泄漏的影响,并对试验数据进行了关联,得出了计算塔板压降、雾沫夹带、泄漏、上限气速、下限气速及操作弹性等的关系式,以便用于网孔塔板的设计。

The flooding point and hold-up of the dispersed phase in an extraction column with reciprocating-sieve plates of 32 mm inside diameter and 1960 mm effective column height have been investigated under the following conditions: Percent perforation of the plates 40%, 53.5% and 63.7%, diameters of perforated holes 7.8, 9.0 and 9.8 mm, and distances between plates 20 and 40mm respectively. Experiments were carried out with three different liquid-liquid systems covering a rather wide range of physical properties.

在塔径32mm,高1960mm的振动筛板萃取塔中,用叔胺N_(235)-TBP-煤油/水等三个无传质体系,进行了液泛点和塔藏量的研究.作者认为两相流过筛孔的实际相对速度,与塔板在单位时间内对单位质量液体所做的功有关,并与体系物性及板间距相关.由于这种想法,建议用A~2F~3代替常用的AF,可以较好地关联本实验数据,和较简明地反映各参数对液泛点和塔藏量的影响,得到了一个新关联式.研究结果指出:①振幅和频率对液泛点和塔藏量的影响是不同的;②分散相的选择无显著影响,③塔板开孔率和板间距是肯定有影响的.实验的振动强度及体系物性参数的范围较宽,塔板开孔率大,板间距小,并采用金属萃取广泛应用的叔胺及二(2-乙基己基)磷酸苹取剂以及煤油稀释后作为有机相.因此,本工作对推广这种塔于金属萃取将有一定的促进作用.
