The Influence of Inlet Pressure Control on Separation Performance of Multi-Product Cyclones

摘要

This paper is devoted and intended to solve the problems of determining the precise separation efficiency andaccurate prediction for the solid yield of multi-product cyclones based on existing experimental data. The influence ofinlet pressure control on separation performance of multi-product cyclones is investigated. Hydrocyclone separationperformance is influenced by many factors such as the liquid level of agitating vessel and the entrance pressure. Theliquid level can also be controlled through the entrance pressure control. The mathematical model of multi-productcyclone system is a high-order complex model and it is difficult to determine the specific expressions. The paper adopts aspecial optimal fuzzy PI_PID control strategy performed by Programmable Logic Controller system to enable inletpressure control. By the force of contrast with experiment and analysis for many performance indexes, the effectivenessand applicability of the control approach are demonstrated. The research provides a method for control of high-ordercomplex system of hydrocyclone separation.
