针对螺旋管分离器介绍了数值模拟模型的选取和基本参数,分别开展了无孔螺旋管和开孔螺旋管的流场模拟。对回转半径和入口流量对流场分布和螺旋管分离器分离性能的影响做了分析。模拟结果表明,螺旋管的回转半径和入口流速是影响分离效果的两个主要因素。另外,螺旋管开孔的孔径尺寸对分离效果也产生一定的影响。在本研究中,当回转半径为500mm、入口速度为0.3m/s时达到理想的分离效果。
The selection of the numerical simulation model and the basic parameters for the spiral pipe separator are introduced. The flow field simulation of the non-porous spiral pipe and the open spiral pipe are respectively carried out. The influence of the radius of gyration and the inlet flow on the distribution of the flow field and the separation performance of the coil separator was analyzed. The simulation results show that the radius of gyration and inlet velocity are the two main factors affecting the separation effect. In addition, the aperture size of the helical opening also has a certain impact on the separation effect. In this study, the ideal separation effect was achieved when the radius of gyration was 500 mm and the inlet velocity was 0.3 m / s.
