紊流是浮选及其微观过程的决定因素。首先,本文论述了可能出现的紊流类型及适当的测量方法。研究了压电和光学传感器。而且,微观过程,即悬浮、空气弥散和气泡-颗粒碰撞分别进行了研究,并在这些模型的基础上,为宏观过程的设计作出结论。目前的研究,必须主要局限于评价浮选过程流体动力学的积分判据。为了进行这种评价,需要绘制专门的曲线图,图中表示,P/V_s=f(C_L),并附加给定参数、叶轮转速n及单位空气流量q_L,还能对悬浮标准及最佳浮选范围加以说明。水力动力学最佳化的实验研究,是在叶轮的类型、转速和底部间隙以及格板的影响下进行的。
Turbulence is the determinant of flotation and its microscopic processes. First, this article discusses the types of turbulence that may occur and the appropriate measurement methods. Piezoelectric and optical sensors were studied. Moreover, microscopic processes, namely suspension, air dispersion and bubble-particle collisions, were studied separately, and on the basis of these models, conclusions were drawn for the design of macroscopic processes. The current research must mainly be limited to the integral criterion for evaluating hydrodynamics of flotation processes. In order to carry out this kind of evaluation, it is necessary to draw a special curve diagram, which shows that P / V_s = f (C_L), with given parameters, impeller speed n and unit air flow rate q_L, Select the range to be explained. Experimental studies on the optimization of hydrodynamics are carried out under the influence of the type of impeller, speed and bottom clearance, and the grate.
