摘要

网角塔板是一种以压延金属板网为面板、以角钢塔板为底盘、重叠而成的复合塔板.从流体力学、乙醇-水二元系精馏及水-空气-氨吸收试验的结果表明

该塔板具有压降低、操作弹性宽、分离效率高、结构简单等优点.网角塔板应用于酒精精馏的实际生产业已取得令人满意的结果.

Abstract

The perforangle plate is a compound column plate composed of perforated plate and angle plate. The hydrodynamics experiments were conducted for the combinations of weir heights of 30mm and 50mm

perforated plate aperture of 26%

39%

52% and angle plate aperture of 8.8%

12.8% in a plexiglass tower 250mm in diameter. The NH3-H2O-air absorption experiments were also conducted in this apparatus. The rectification for ethanol-water system at infinite reflux

was performed under atmospheric pressure for the combinations of weir heights of 30mm and 50mm

and perforated plate aperture of 32.5%

17.45% and angle plate aperture 8.39% in a stainless steel tower 257mm in diameter. Some useful equations for engineering design were obtained. The advantages of high separation efficiency

low pressure drop and wide operation range of perforangle plate have been confirmed by alcohol production.
