Rotary extraction tower belongs to the mechanical stirring extraction tower, referred to as RDC, consists of three parts: the clarification section, mixed, clarify under paragraphs. Which mixed section is a cylinder, the internal is static ring baffles are divided into a series of extraction chamber, between two static ring baffle is fixed wheel, and together with the stirring shaft rotation. At work, the heavy and light phase respectively by the top and bottom to enter, in a countercurrent extraction tower contact, under the fixed wheel agitation, dispersed droplet formation, make the transfer. 。 。

rotary extraction tower belongs to the mechanical stirring extraction tower, referred to as RDC, consists of three parts: the clarification, mixed period, under the clarification section. Which mixed section is a cylinder, the internal is static ring baffles are divided into a series of extraction chamber, between two static ring baffle is fixed wheel, and together with the stirring shaft rotation. At work, the heavy and light phase, respectively from the top and bottom to enter, in a countercurrent extraction tower contact, under the fixed wheel agitation, dispersed droplet formation, increase the mass transfer area, after completing the process of extraction, light and heavy phase respectively by the top and bottom out.

rotary extraction tower can be applied to all the liquid - Liquid extraction process, must especially two-phase countercurrent or and flow process. System can contain a small amount of suspended solids in the middle. In principle, extraction tower can also be used for mass transfer or no mass transfer by chemical reaction.
