Abstract

The invention relates to an extraction device in magnetic mixing dispersion system adopting acidity hydrophobic ionic liquid with magnetic function as extractant. There is a reaction tank, of which the bottom middle part is concave. In the concave groove there is a vertical round Nd-Fe-B permanent magnet connected with the shaft of rotary motor. The outlet port for magnetic ionic liquid is set on the wall at one side of lower part of reaction tank. The inlet port for magnetic ionic liquid and inlet port for substance liquid are set on the wall at the other side. Magnetically stabilized bed coil is set on the outer side wall of upper part of reaction tank. Liquid inlet port of a ring dispersion device is docked with the port for substance liquid in the reaction tank. The magnetically stabilized bed coil controls mutual impact and condensation of magnetic ionic liquid pearls with dispersion phase. The extraction device realizes two operation states of one tower. Water solution in magnetic ionic liquid phase is in dispersion phase and ionic liquid in water solution phase is in dispersion phase. So entrainment phenomena are decreased. The device power is far lower than normal mixing device and energy consumption in extraction process is decreased.

Description

technical field

[0001] The present invention relates to the extraction device of magnetic ionic liquid as medium and extraction agent, specifically the extraction device of magnetic stirring dispersion system with acidic and magnetically functional hydrophobic ionic liquid as extraction agent, and is also suitable for magnetic ionic liquid as Rotating, steady-field extraction apparatus for other two-phase processes of media. technical background

[0002] In the 1960s, Filippov proposed a new type of fluidized bed system, which is a fluidized bed with magnetic particles as the solid phase under the action of an external magnetic field. According to the direction of the magnetic field, it can be divided into axial magnetic field fluidized bed and transverse magnetic field fluidized bed. The magnetically stabilized bed is a stable bed formed under the action of a uniform external magnetic field whose axial direction does not change with time, and it is a very promising reactor...
