摘要：在直径1 000 mm、高6 m中试规模的不锈钢圆形塔内,采用空气-水物系进行冷模实验,对波纹导向浮阀塔板的雾沫夹带性能进行了研究,考察了液流强度、出口堰高等因素对其雾沫夹带的影响,并比较了带孔、不带孔波纹导向浮阀和F1型浮阀的雾沫夹带分率。结果表明,波纹导向浮阀塔板在不同的液流强度下都具备较好的操作弹性;带导向孔的波纹浮阀塔板的雾沫夹带率较无导向孔低,证明了浮阀上方开导向孔的优越性;在较大的空塔动能因子下,带导向孔波纹浮阀塔板的抗雾沫夹带性能明显优于F1型浮阀。
Entrainment rate of wave directed float valve trays is studied by using air-water system in a column with a diameter of 1 000 mm and height of 6 m. The influence of the liquid weir load and outlet weir height on entrainment are studied. The comparison of the performance of F1 valve and wave float valve with or without directed holes is performed.The results show that wave directed float valve has a wide operation range. Wave float valves with directed holes present lower entrainment rate than those without directed holes under the same operating conditions,which proves the necessity of directed holes. At larger empty tower F factor,entrainment rate of wave directed float valve trays is 10%- 20% lower than F1 valve trays. Obviously,wave directed float valve has better anti-entrainment characteristics.
