The Computer Controlled Hydrocyclone Unit, "PHCC", designed by EDIBON, allows the complete study of the solid-liquid separation process by centrifugal action. This laboratory unit accurately reproduces the operating conditions of hydrocyclones used in water treatment, mining, petrochemical, or food industries, providing an educational and research tool for analyzing hydraulic efficiency and particle distribution.
The process begins in a main tank where the suspension of solids in water is prepared. A stirrer, computer-controlled, keeps the mixture homogeneous to prevent the sedimentation of dense particles. A hydraulic pump, also controlled by software, drives the fluid toward the hydrocyclone through the feed circuit. The flow rate can be adjusted by means of a valve and a bypass circuit, allowing precise control of operating conditions.
At the cyclone inlet, pressure and flow sensors record the main process variables, whose values are monitored in real time through the software. This design allows simultaneous control of the pump and stirrer speeds, ensuring stable and reproducible operation.
Inside the hydrocyclone, the centrifugal acceleration generates a high-velocity vortex, in which the coarser particles move toward the internal wall and descend to the lower outlet, where they are discharged. The geometry of the lower part of the cyclone produces a central upward flow that carries the finer particles and clarified liquid toward the upper outlet. A stable air core is formed along the cyclone axis, helping to maintain the structure of the vortex and the separation between the descending and ascending flow zones. In this way, two differentiated streams are obtained: one rich in concentrated solids and the other with clarified liquid, both collected in separate tanks.
The upper part of the cyclone is made of transparent material, allowing direct observation of the flow and vortex formation, which facilitates visual interpretation of the separation process and the analysis of internal flow phenomena.
Both streams can return to the main tank, allowing the process to be repeated in order to study the influence of operating conditions on separation efficiency. The tank includes a level indicator and sampling points at the solid and liquid outlets, facilitating experimental analysis. By studying the collected samples, it is possible to determine the separation efficiency, calculate the cut diameter, and plot the classification curve of the hydrocyclone.
The unit is supplied with test materials quartz sand and diatomaceous earth which make it possible to compare the behavior of particles of different densities and sizes, and to evaluate their influence on process performance.
This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
