垂直粘结矩形斜管沉淀技术的研究

Research on Sedimentation Technique of Tube Settler withRectangular Cross-section and Vertical Adhesive Interface

提出了一种新颖的垂直粘结矩形斜管，其斜管体具有平整的顶面和底面。试验研究表明，它还具有良好的沉淀性能、较大的经济效益和斜管全长均起着固液分离作用———起端不存在“由紊流变层流”的过渡段。

A new type of tube settler with rectangular cross-section and vertical adhesive interface in the tube module is proposed.The tube module by this kind of tube settler has flat top and bottom faces.Experiments show that the tube settler with rectangular vross-section and vertical adhesive interface has the advantages of better sedimentation performance,less material censumption for its construction and no flow transitional section from turbulent flow to laminar flow in the inlet part of the tube of which the whole length takes part in solid-liquid separation.
