The invention provides a rotary screen tower for liquid-liquid extraction. The rotary screen tower comprises an organic phase clarifying section, a mixing section, a water-phase clarifying section, a driving mechanism, a first fixed screen, a second fixed screen and a rotating shaft, wherein the mixing section is located between the organic phase clarifying section and the water-phase clarifying section; the first fixed screen is mounted on an interface of the organic phase clarifying section and the mixing section; the second fixed screen is mounted on an interface of the mixing section and the water-phase clarifying section; the driving mechanism is arranged at the top of the organic phase clarifying section; one end of the rotating shaft is connected with the driving mechanism and the other end of the rotating shaft penetrates through the organic phase clarifying section and the first fixed screen to stretch into an inner cavity of the mixing section to be arranged on a supporting base at the bottom of the mixing section; the mixing section is at least composed of two tower sections; each section of the tower section is at least provided with an extracting chamber; each extracting chamber is enclosed by a corresponding tower section shell and two annular horizontal baffles arranged in the shell; and each extracting chamber is internally provided with a vertical baffle and a rotating screen, wherein the vertical baffle is mounted on the inner wall of the shell, and the rotating screen is mounted on the rotating shaft.
Description
technical field [0001] The invention belongs to liquid-liquid extraction equipment used in chemical or biological engineering, in particular to a liquid-liquid extraction tower. Background technique [0002] Extraction tower is an important extraction equipment, among which vibrating sieve plate tower and rotating disk tower are widely used in petrochemical, hydrometallurgy and chemical industry and other fields. Although the processing capacity of the vibrating sieve plate tower and the rotary table tower is relatively large, with the expansion of modern production scale, its processing capacity needs to be further improved. [0003] The turntable tower relies on the rotation of the turntable, so that the liquid is broken into droplets on the outer edge of the turntable, and the size of the droplet is controlled by the speed of the turntable. Therefore, in order to increase the phase boundary area between the two extraction phases and enhance the mass transfer between the ...
