塑料异型矩鞍填料的流体力学及传质性能研究

在内径300 mm塔中,以空气-氨-水为物系,对开发出的一种新型塑料散装填料———异型矩鞍填料的流体力学及传质性能进行了研究。获得了该填料的几何特性、流体力学性能及传质性能数据,并通过对实验数据的回归分析,得出了填料层压降Δp/Z、泛点填料因子F及气相总传质单元高度HOG的关联式。研究结果表明,塑料异型矩鞍填料具有通量大、压降低、气液分布均匀及传质性能优良等优点。

Hydrodynamic and mass transfer performances of plastic abnormity intalox packing

A new pattern plastic bulk packing,namely abnormity intalox packing,was exploited.The hydrodynamic and mass transfer performances of the plastic abnormity intalox packing were investigated in a 300 mm column with air-NH_3-H_2O system.The geometric characteristic,hydrodynamic and mass transfer performances of the packing were obtained.Through regressing experimental data, the correlative expression of pressure drop Δp/Z,factor of flooding point _F and the height H_(OG) of overall mass-transfer unit based on gas phase was presented.The results show that the packing has the advantages of great flux,lower pressure drop,uniform gas-liquid distribution and excellent mass transfer performance.
