Abstract

The invention discloses a labyrinth type hypergravity liquid-liquid extraction separator which comprises a housing, a filler helix tube, a mixed mass transfer mechanism, a separation collection mechanism, a top cover plate, a pedestal, a bearing sleeve, a shaft and a motor. The mixed mass transfer mechanism comprises a feed planet impeller mixing device, a mass transfer device and conical milling fluid wheels. The mass transfer device is arranged between the feed planet impeller mixing device and the conical milling fluid wheels. The separation and collection mechanism comprises a phase-splitting trough, a spring switch and a collecting tank. By the extraction separator provided by the invention, high-efficiency extraction is realized, and two-phase separation is also considered. A multi-layer packing structure increases mass transfer area of a two-phase fluid. Due to the complex packing layer structure, mixing is more uniform. Reaction time is prolonged, and extraction rate is enhanced. The separation and collection mechanism, used as an important part of the extraction process, realizes integration of extraction and separation.

Description

technical field [0001] The invention relates to a labyrinth type supergravity liquid-liquid extraction separator, which belongs to the technical field of mass transfer enhancement. Background technique [0002] High-gravity liquid-liquid extraction separation technology has been widely used in the fields of biochemistry and biochemical industry because of its good extraction effect. However, the residence time of the current equipment is too short during the extraction process, and its single-layer packing structure makes the mass transfer area too small. In addition, there are many shortcomings such as high equipment manufacturing cost, bulky volume, slow extraction rate and low extraction efficiency. At present, there are few talents and equipment in the field of metallurgy, and most of the existing high-gravity engineering technology devices rotate with the entire rotor, and most of them have a single-layer packing structure, so the mixing and mass transfer are not thoro...
