Establishing and Anatomizing with Respect to Inclined-Plate (Pipe) Sedimentation Separation Mathematical Models

摘要: 在油田污水处理过程中，斜板(或斜管)除油器用于强化油水分离、去除污水中的细小油滴，斜板(管)工艺结构尺寸的设计与优化是影响斜板(管)除油效率的关键。本文运用沉降理论，通过数学分析，针对3种水流形式，构建了8种物理模型，在此基础上建立了3套数学模型，为斜板(管)工艺结构的优化设计提供了可量化的理论依据；同时，对斜板(管)相关设计参数也进行了探讨。

Abstract: During oilfield produced water treatment, the inclined-plate (or beehive pipe ) deoiling device was used to enhance the effect of oil/water separation, remove exiguous oil droplets from sewage. The design and optimization of the plate (pipe) structure was naturally the key of the degreasing effect. Therefore, according to settlement theory and mathematical analysis, for the 3 kinds of water current forms, this text established 8 kinds of physical models, on this basis, 3 kinds of mathematical models were built to provide quantitative theoretical foundation for optimizing design of the plate (pipe) structure. At the same time, relevant design parameters of the inclined plate (pipe) were probed in the research.
