Abstract

The invention relates to a dividing wall type continuous extraction tower, and belongs to the technical field of chemical equipment. The dividing wall type continuous extraction tower comprises a motor, a tower main shaft, a tower barrel body, an upper feeding distributor, a lower feeding distributor, a stirrer, an extraction unit, a light phase inlet, a heavy phase inlet, a light phase outlet anda heavy phase outlet; a motor is arranged at the upper end of the tower barrel, a tower main shaft is arranged along the central axis of the tower barrel, and the motor is connected with the tower main shaft; an up-and-down feeding distributor is arranged in the tower barrel body; a plurality of extraction units are continuously arranged between the upper feeding distributor and the lower feedingdistributor; a stirrer is arranged in the extraction unit; the upper feeding distributor is connected with the heavy phase inlet, and the lower feeding distributor is connected with the light phase inlet; and a light phase outlet is formed above the upper feeding distributor, and a heavy phase outlet is formed below the lower feeding distributor. According to the invention, in a plurality of continuously arranged extraction units, the physically separated mixing mass transfer area and clarification phase separation area are arranged to improve the mass transfer effect and the phase separationeffect and reduce the influence of back mixing; and the overall extraction effect is remarkably improved.

Description

technical field [0001] The invention relates to a partition-type continuous extraction tower, which belongs to the technical field of chemical equipment. In the present invention, the liquid flow direction of the extraction tower is defined as up and down directions, the light phase liquid flows from bottom to top, and the heavy phase liquid flows from top to bottom. Background technique [0002] In the late 1940s, due to the demand for nuclear fuel production, the technology of liquid-liquid extraction using two liquids with different densities that are immiscible has achieved considerable development, and has gradually become popular in petrochemical, chemical engineering, metallurgy, Food, traditional Chinese medicine extraction and atomic energy industry have been widely used. [0003] There are many types of extractors that extraction technology relies on, and extraction towers are one of them. As we all know, the extraction towers commonly used in the industry are ma...
