研究用于污泥脱水的卧螺离心机的分离性能,并应用FIUENT软件建立卧螺离心机螺旋流道内污泥流体的两相湍流三维模型。主要研究不同转鼓长径比对卧螺离心机分离性能的影响,间接给出了不同长径比对卧螺离心机分离性能的影响关系图,并得到了该卧螺离心机最佳转鼓长径比的几何尺寸,为进一步研究离心机特性参数对其分离性能的影响和结构优化提供了理论依据。
The separation performance of a decanter centrifuge for sludge dewatering was studied. A three-dimensional turbulent three-dimensional model of the sludge fluid in the spiral flow channel of a decanters centrifuge was established by FIUENT software. The effects of different aspect ratios on the decoupling performance of decanter centrifuge were studied. The relationship between different aspect ratio and decanter decanter centrifuge performance was given indirectly. The optimum decanter of decanter centrifuge The geometric dimension of aspect ratio provides a theoretical basis for further study on the influence of centrifuge characteristics on its separation performance and structural optimization.
