为提高卧式分离器的固体颗粒分离性能,采用单因素和正交法实验研究了液位、入口液体流量、颗粒粒径对分离器固体颗粒分离效果的影响。结果表明:粒径大于65 μm的颗粒分离效果较好,受液位高度影响不明显;随着液位高度增大至0.5 D,在流量小于60 L / h时,分离效率逐步增大到90%;排液口颗粒中位粒径相对稳定在6~18 μm;三种变量对分离效率的影响大小依次为:颗粒粒径、液位、入口液体流量;在显著性水平γ=0.05条件下,颗粒粒径影响最为显著。研究能为卧式分离器固体颗粒分离性能的调节提供参考。

In order to improve the solid particle separation performance of the separator, the effects of liquid level, inlet liquid flow rate and particle size on the separation efficiency of solid particles in horizontal separator are studied by single factor and orthogonal experiments.The results show that the separation efficiency of solid particles with particle size larger than 65 micron is higher, and the influence of liquid level height is not obvious;with the increase of liquid level height to 0.5D, the separation efficiency of solid particles in horizontal separator is improved. When the mass separation efficiency is less than 60 L/h, it gradually increases to 90%;the median particle size of the outlet is relatively stable at 6-18 um;the influence of three variables on the separation efficiency is in turn: particle size > liquid level > inlet liquid flow rate;the particle size is the most significant effect at the significant level of a=0.05.
