The new type of turbine extraction column is a rotating agitator tower extraction device. 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 fixed on the rotating shaft. The turbine rotates within the compartments to generate a characteristic flow pattern, keeping the fluid in a turbulent zone inside the tower. Due to the stronger shearing action of the turbine on the liquid compared to a general rotating disk, the mixing effect of the turbine extraction column is much more intense, allowing for thorough dispersion of droplets, which is beneficial for mass transfer.

The extraction tower is a differential contact tower where the entire tower fluid is in continuous contact. There is two-phase separation at the inlets and outlets. The 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.

The industrial turbine extraction tower consists of five main parts: oil-water separator (upper and lower), tower body, disk system, feed and discharge system, and electrical control system. The inner diameter and height of the tower are customized according to the customer's process materials. Several static rings are set at certain intervals on the inner wall of the tower. The turbine (moving ring, disk) is fixed on the central shaft, and the static rings divide 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 is a theoretical stage, and the two-phase liquids achieve multi-stage countercurrent contact mixing during the countercurrent process.

Process of work

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 flows out from the bottom. Both phases flow in opposite directions within the tower.

Turbine impeller: Provides necessary radial mixing and phase dispersion, with the design of the turbine blade optimized based on fluid dynamic research data to produce more uniform droplet sizes of the dispersed phase and to more accurately predict the flow characteristics of two-phase fluid mechanics.

Tray: Separated to form a single compartment, which can reduce fluid axial backmixing while achieving a high dispersed phase residence time.
