Filling Extraction Tower

Filling Extraction TowerIt is a rotary mixing tower-type extraction equipment. 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 mixer, by rotating within the compartments, generates a characteristic flow pattern, keeping the fluid inside the tower in a turbulent zone. Due to the stronger shearing action of the turbine compared to a general rotating disk on the liquid, the mixing effect of the turbine mixing extraction tower 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 has continuous contact. Two-phase separation occurs at the inlet and outlet. A model based on the droplet swarm theory better describes the fluid flow characteristics within this type of tower. The droplet swarm model is a complete statistical description of the system, being a function of the 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, turbine disc 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, disc) 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 by 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

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 the necessary radial mixing and phase dispersion, with the design of the turbine blade optimized based on fluid dynamic research data to achieve more uniform droplet sizes of the dispersed phase and more accurate prediction of the flow characteristics of two-phase fluid mechanics.

Tray: Separated to form a single compartment, it can reduce the axial backmixing of fluids while achieving a high dispersed phase residence time.
