The cyclone separator has the advantages of few required system accessories, low maintenance cost, easy adjustment, strong control adaptability, high separation efficiency, continuous operation and the like, and is widely applied to multiple fields of chemical industry, petroleum, electric power, environmental protection, metallurgy, water treatment and the like. The hydrocyclone is generally evaluated in working performance by separation efficiency and size fraction efficiency during use, and the applicability of the hydrocyclone is tested in turn. In practical applications, there are many factors that affect the separation performance of a hydrocyclone, where the overflow split rate of the hydrocyclone is an important operating parameter as well as an important performance parameter in the cyclonic separation process. The overflow separation rate of a cyclone has a significant effect on the separation efficiency of the cyclone. During the use process, the overflow flow rate of the cyclone can be mainly adjusted in two ways, one is to control the overflow flow amount by adjusting the opening and closing size of an overflow outlet valve, and the other is to control the overflow flow amount by replacing overflow pipes with different pipe diameters. However, the above two methods are complicated in operation process, and it is difficult to adjust the pipe diameter of the overflow pipe timely and continuously to achieve the optimal overflow flow splitting rate. In the practical application process of the cyclone, the application of the cyclone is limited due to low separation efficiency of the cyclone under the separation working condition of unstable liquid inlet amount because the cyclone cannot maintain the optimal flow splitting rate.
