近菱形斜管沉淀装置试验研究

EXPERIMENTAL RESEARCH OF TUBE-SETTLER WITH NEARLY RHOMBOHEDRAL CROSS-SECTIONAL TUBES

本文通过对不同斜管断面形状的分析,指出斜管断面形状不同,其沉淀面积也不同,沉淀面积较大的斜管,应有较高的沉淀效率,从而设计出比蜂窝斜管沉淀面积更大的近菱形斜管。通过模型及半生产性试验研究证实,近菱形斜管确实是比蜂窝斜管沉淀效率更高的新型斜管沉淀装置。

In this paper,the authors consider that,for the tube-settler,different cross-sectional shaped tubes give different settling areas. The new oblique tube-settler with nearly rhombohedral cross-sectional tubes gives larger settling area than those old ones that are with honeycomb cross-sectional tubes. The results of the pilot experiment show that the new tube settler with larger settling area gives better settling effect than the old, with smaller area ones.
