Description
Technical Field
The utility model relates to a turbine extraction tower.
Background
The turbine extraction tower is a common liquid-liquid separation device and has wide application in the fields of chemical industry and the like.
The prior turbine extraction tower, such as the turbine extraction tower reported in ' the application of the turbine extraction tower in lincomycin extraction ' in the third stage P391 of 2017 ', comprises a tower body, a tower plate and a turbine stirring paddle, wherein the tower body, the tower plate and the turbine stirring paddle are sequentially connected with one another by an upper clarification section, an extraction section and a lower clarification section;
in the turbine extraction tower, a turbine stirring paddle is arranged between every two tower plates, and fluid is enabled to swirl between the two tower plates under the rotating action of the stirring paddle to generate a centrifugal action. Since one phase of the fluid is a continuous phase and the other phase is a dispersed phase, the two phases flow in countercurrent due to the density difference. As the continuous phase flows, there is a drag of the fine dispersed phase droplets with the continuous phase, and thus, the fine droplets of the dispersed phase present in the continuous phase fluid flow rotationally with the continuous phase. This phenomenon causes back-mixing of the dispersed phase, increases entrainment of the continuous phase, and reduces extraction efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a turbine extraction tower with stationary flow bars to overcome the defect that prior art exists.
The turbine extraction tower with the flow stabilizing grid comprises a tower body, a tower plate, a turbine stirring paddle, an upper flow stabilizing grid and a lower flow stabilizing grid, wherein the tower body, the tower plate, the turbine stirring paddle, the upper flow stabilizing grid and the lower flow stabilizing grid are sequentially connected with one another through an upper clarifying section, an extraction section and a lower clarifying section;
the stirring shaft extends upwards from the lower part of the extraction section, penetrates through the tower plate and the upper steady flow grid to the outside of the top of the upper clarification section, and is connected with a power mechanism;
the utility model has the advantages that: the steady flow grid has the main function that the fluid in the extraction section of the extraction tower stops rotating rapidly from rotating and flows in a plug flow manner, so that after the fluid is separated from the extraction section of the extraction tower, the light and heavy two-phase fluids stop rotating in respective clarification sections to separate phases. Avoiding back mixing of the dispersed phase, reducing entrainment of the continuous phase and greatly improving extraction efficiency.
