小比表面积双曲型规整填料性能的冷模实验

双曲型丝网波纹填料是具有特殊弧形波纹结构的一种新型规整填料。本文选取比表面积分别为350和500m2/m3的填料进行冷模实验,并测试其流体力学和传质性能。将上述2种填料与350Y和500Y进行对比,结果显示,在实验气速范围内,L=25.48m3/(m2·h)时,Kxa(SQ-350)=(1+54.9%)Kxa(350Y);当F为0.6m/s·(kg/m3)0.5,15.29m3/(m2·h)≤L≤35.67m3/(m2·h)时,Kxa(SQ-500)=1+(13.3%～66.7%)]Kxa(500Y)。此外,新填料适合在大液量下操作,且能耗低于350Y和500Y。

Cold-flow model tests of the performance of SQ type structured packings with small surface area

In order to improve the performance of traditional packings with linear corrugated structures, two kinds of hyperbolic mesh packings with specific surface areasof 350m²/m³ and 500m²/m³have been introduced,and a series of cold-flow model tests were carried out to obtain their performance characteristics. Compared with 350Y and 500Y, the experimental results showed that: when the gas velocity was in the experimental range and L=25.48m³/(m²·h), K_xa(SQ-350)=(1+54.9%)K_xa(350Y); when F=0.6m/s·(kg/m³)^0.5 and 15.29m³/(m²·h)≤L≤35.67m³/(m²·h), Kxa(SQ-500)=［1+(13.3%-66.7%)］K_xa(500Y). The results also showed that the new packings were suitable for operations with large fluid volumes and their energy consumption was lower than 350Y and 500Y.
