An industrial turbine extraction tower is a rotating agitator type tower extraction unit. A series of sieve plates (stationary rings) divide the tower body into several stages along the axial direction. Between every two fixed sieve plates, there is a turbine-type mixer mounted on the rotating shaft. The turbine rotates within the compartments to generate characteristic flow patterns, keeping the fluid in a turbulent zone. Due to the stronger shearing action of the turbine on the liquid compared to a general rotating disc, the mixing effect of the turbine extraction tower is much more vigorous, allowing for thorough dispersion of droplets, which is conducive to mass transfer.
The extraction column is a differential contact tower where the fluid is in continuous contact throughout the tower, with two-phase separation at the inlets and outlets. A model based on the droplet cluster theory better describes the fluid flow characteristics within this type of tower. The droplet cluster model is a comprehensive statistical description of the system, being a function of droplet size, concentration, and related properties in the dispersed phase.
Industrial TurbineExtractive columnComposed of five main parts: oil-water separator (upper and lower), tower body, turntable system, feeding and discharging system, and electrical control system. The tower inner diameter and height are customized according to the customer's process material. Several static rings are set at certain intervals on the tower inner wall. The turbine (moving ring, turntable) is fixed on the central shaft, dividing the tower into several mixing zones. In each mixing zone, the liquid is mixed through the moving ring to achieve two-phase mixing. Each mixing zone serves as a theoretical stage, allowing two-phase liquids to achieve multi-stage countercurrent contact mixing during the reverse flow process.
Work Process
The oil phase (light phase) enters from the bottom of the tower and overflows from the top; the water phase (heavy phase) is added at the top and exits from the bottom. Both flow in opposite directions within the tower.
Turbine impeller: Provides the necessary radial mixing and phase dispersion, with the design of the turbine blade optimized based on fluid dynamics research data to achieve uniform droplet sizes of the dispersed phase and more accurate predictions of the flow characteristics of two-phase fluid mechanics.
Towers: Separated to form a single compartment, they can reduce the axial backmixing of fluids while achieving a high residence time for the dispersed phase.
