Description

Technical Field

[0001] The utility model belongs to the field of extraction equipment, and specifically relates to a centrifugal stirring extraction tower device. Background Art

[0002] Liquid-liquid extraction towers have the advantages of simple structure, good sealing, and large production capacity. They are widely used in many fields such as petroleum, chemical industry, biology, medicine, and environmental engineering. The internal structure of the extraction tower uses gravity or mechanical action to break a liquid into droplets, disperse them in another continuous liquid, and perform liquid-liquid extraction. In order to enhance the liquid-liquid mixing during the extraction process, various types of extraction towers have been developed in the prior art, including sieve plate pulse extraction towers, plate ring pulse extraction towers, packed extraction towers, and turntable towers. All kinds of extraction towers have enhanced dispersion as the optimization goal. However, the enhanced dispersion of the existing extraction towers mentioned above is either complex in structure and high in cost, or the dispersion effect is not ideal.

[0003] The utility model patent publication with announcement number CN201664526U discloses a centrifugal stirring extraction tower, which achieves the effect of efficient centrifugal extraction by making specific settings of the rotating parts. However, this technical solution cannot achieve a better breakup effect of the droplets during the extraction process, so the mass transfer specific surface area of ​​the droplets is not ideal.

[0013] Furthermore, the bottom of the extraction tower top is connected to the top of the tower body through a flange and is sealed by a sealing material, and the top of the extraction tower bottom is connected to the bottom of the tower body through a flange and is sealed by a sealing material.

[0021] The technical effects of the utility model are:

[0022] The utility model sets centrifugal internal components and spacer ring plates, and specifically defines the shape structure of the centrifugal internal components, the positional relationship with the spacer ring plates and other technical features, so that the dispersed phase droplets can achieve centrifugal and crushing effects due to the rotational centrifugal effect of the specific internal components during the rising or falling process. At the same time, the positional relationship between the centrifugal internal components and the spacer ring plates is set so that the dispersed phase droplets flow in a specific baffled form after centrifugation and crushing, thereby further strengthening the crushing and mass transfer specific surface area effect. At the same time, by defining the angle between the centrifugal internal components and the central column, the dispersed phase droplets are guaranteed to increase the mass transfer specific surface area of ​​the droplets and the dispersed phase holdup during the flow process without excessive retention of the dispersed phase droplets. Therefore, the mass transfer specific surface area of ​​the droplets and the dispersed phase holdup are increased through the setting of the overall structure, and the mass transfer efficiency is improved.
