Abstract

The invention relates to the technical field of design and manufacture of hydro-cyclones, in particular to a numerical simulation and optimization method for parameters of solid-solid separation hydro-cyclones. The method mainly comprises the following operation steps: determining the basic diameter of a hydro-cyclone; determining other structural parameters of the hydro-cyclone; designing a quadratic orthogonal rotation combinative test scheme; carrying out numerical simulation and test optimization on operation parameters; designing an orthogonal test scheme; carrying out numerical simulation and test optimization on the structural parameters. In order to overcome the disadvantages and defects in the prior art, the invention provides a method for carrying out multivariable multi-target parameter optimization on the operation parameters and structural parameters of the solid-solid separation hydro-cyclones by taking separation performance of the hydro-cyclones as target, so as to simply, economically and efficiently realize the parameter optimization of the hydro-cyclones, remarkably improve the separation performance of the hydro-cyclones, improve the production efficiency, reduce the production cost and improve the product quality.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of hydrocyclones, and more specifically, relates to a numerical simulation optimization method for parameters of a solid-solid separation hydrocyclone. Background technique [0002] Hydrocyclone is a commonly used two-phase separation equipment in industrial production. It has many advantages such as simple structure, convenient operation, large production capacity, high separation efficiency, and small footprint. [0003] The application of hydrocyclone includes solid-liquid separation, liquid-gas separation, solid-solid separation, liquid-liquid separation, liquid-gas-solid three-phase simultaneous separation, etc. The basic working principle of the hydrocyclone as a separation and classification equipment is based on centrifugal sedimentation. When the two-phase mixed liquid to be separated enters the device from the inlet of the hydrocyclone at a certain pressure, it will produ...

Problems solved by technology

[0008] Theoretically, the performance of the hydrocyclone can be analyzed and described through its internal flow field, but the structure and operation of the hydrocyclone seem simple, but its internal flow field is extremely complex. A lot of research has been done in the field, and many theories, methods and empirical models have been proposed for the design and optimization of hydrocyclones. However, due to the influence of many influencing factors and their interactions on hydrocyclones, the existing methods have many deficiencies. : or lack of generality based on certain specific conditions; or remove multiple influencing factors; or remove the interaction between factors; or simply analyze and optimize from a qualitative point of view; or rely on a large number of experiments, the workload and cost are huge, Low efficiency, it is difficult to be used for reference by specific engineering applications
