The 500-turbine extraction column made of 316L stainless steel is a rotating agitator type tower extraction equipment. With a tower diameter of 300mm, 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 effect of the turbine on the liquid compared to a general rotating disk, the mixing action of the turbine extraction column is much more vigorous, allowing for thorough dispersion of droplets, which is beneficial for mass transfer.

The extraction column is a differential contact tower where the entire tower fluid is in continuous contact. Two-phase separation occurs at the inlets and outlets. The model based on the droplet swarm theory better describes the fluid flow characteristics within this type of tower. The droplet swarm model provides 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, turntable system, feed and discharge system, and electrical control system. The internal diameter and height of the tower are customized according to the customer's process material. Several static rings are set at certain intervals on the inner wall of the tower. The turbine (moving ring, turntable) 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.

Work Process

Oil phase (light phase) enters from the bottom of the tower and overflows from the top; water phase (heavy phase) is added at the top and exits from the bottom, with the two flowing in opposite directions within the tower.

Turbine impeller: Provides necessary radial mixing and phase dispersion, with the design of the turbine impeller 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: Separates into individual compartments, reducing fluid axial backmixing while achieving excellent dispersed phase retention rate.
