【摘要】：为了使螺旋除砂器能够在不同工况下保持较高的分离效率,对其结构参数与分离效率间的关系进行研究。依据工程流体力学中的伯努利方程建立了螺旋除砂器相关结构参数的数学模型,借助FLUENT流体仿真软件对其内部流场进行仿真,并利用数据拟合的方法对结果进行分析。通过对仿真云图8个不同标记点的模拟数据的处理,得到混合流体流速在4.15~4.52 m/s之间时,最大分离效率为5%,随着流体速度的增大,分离效率也会有所提高,当流体速度增大到6.79 m/s时,模拟分离效率能达到95%以上。研究结果表明,混合流体流速V分别与螺旋除砂器总高H、螺旋管中径D间为线性递增关系,而与螺旋管管材内径d间存在线性递减关系,为螺旋除砂器的设计制造提供了理论依据。
[Abstract]:In order to be able to maintain a high separation efficiency under different working conditions, the relationship between the structural parameters and the separation efficiency is studied. According to the Bernoulli equation in the engineering fluid mechanics, a mathematical model of the relevant structural parameters of the spiral sand remover is established, and the internal flow field is simulated by the FLUENT fluid simulation software, and the results are analyzed by means of the method of data fitting. The maximum separation efficiency is 5% when the flow velocity of the mixed fluid is between 4.15 and 4.52 m/ s by the processing of the simulation data of 8 different mark points of the simulation cloud image, and the separation efficiency can be improved as the fluid speed is increased, and when the fluid speed is increased to 6.79 m/ s, And the simulated separation efficiency can reach more than 95 percent. The results show that the mixed fluid flow rate V is linearly increasing with the total height H of the spiral sand remover and the diameter D of the spiral pipe, and there is a linear decreasing relation with the inner diameter d of the spiral pipe, so as to provide a theoretical basis for the design and manufacture of the spiral sand remover.
