The rotary disc extraction tower has the advantages of simple structure, large treatment capacity, low investment and the like. Therefore, since their introduction, they have been widely used in the pharmaceutical, fine, and petrochemical industries.

The basic structure of the rotary disc extraction tower is that a plurality of annular baffles are arranged on the inner wall surface of the tower body at certain intervals, and the annular baffles are called as static rings which divide the tower into a plurality of small spaces. A movable ring is arranged between the two stationary rings. The rotating ring is fixed on a rotating shaft, and the rotating shaft is driven by a motor of the tower. The diameter of the movable ring is smaller than the inner diameter of the stationary ring, so that the movable ring is convenient to assemble and disassemble. During extraction, the moving ring rotates with the rotating shaft at high speed, and the shearing stress generated in the liquid breaks the dispersed phase into many small liquid quotient and generates strong vortex motion in the liquid phase, so that the interphase contact area and the mass transfer coefficient are increased. Meanwhile, the existence of the static ring inhibits axial back mixing to a certain extent, so that the mass transfer efficiency of the rotating disc extraction tower is higher.
