Abstract

The invention discloses a stripping device which comprises an emulsifying machine (1) and phase splitting equipment (2), wherein an emulsifying machine inlet (3) and an emulsifying machine outlet (4) are arranged on the emulsifying machine (1), a mixed-phase inlet (5), a heavy-phase outlet (6) and a light-phase outlet (7) are arranged on the phase splitting equipment (2), the emulsifying machine inlet (3) is connected with a stripping agent inlet (8) and a solvent inlet (9), and the emulsifying machine outlet (4) is connected with the mixed-phase inlet (5) of the phase splitting equipment. When multiple stages of stripping devices are combined, the light-phase outlet of the phase splitting equipment in the stage of stripping device is connected with the solvent inlet in the next stage of stripping device through a pipeline provided with a pump; and the heavy-phase outlet of the phase splitting equipment in the next stage of stripping device is connected with the stripping agent inlet in the stage of stripping device through the pipeline provided with the pump. The invention can strengthen the mass transfer performance, improve the stripping efficiency and lower the stripping equipment investment and the operating cost.

Description

technical field

[0001] The invention relates to the field of chemical equipment, in particular to a stripping device. Background technique

[0002] Extraction and stripping is a way to achieve mass transfer between two liquid phases in the chemical industry. At present, the chemical equipment used for extraction and stripping is mainly as follows: multi-stage mixing-settling tank, which is a typical step-by-step contact liquid-liquid mass transfer Equipment, in which each stage includes a mixer and a clarification tank. The main disadvantages of this equipment are: the horizontally arranged multi-stage mixing-mixing tank occupies a large area, each stage is equipped with a stirring device, and the fluid between stages The flow generally needs to be pumped, and the equipment cost and operating cost are relatively large; the sieve plate tower, the light and heavy phases flow countercurrently in the tower, and the two phases are in cross-flow contact on each tray. The mass tran...
