Rotary extraction tower belongs to the mechanical stirring extraction tower, referred to as RDC, it consists of belt of vertical cylinder horizontal static ring baffle. Static ring baffle as the center hole plate, static ring baffle cylinder can be divided into a series of extraction, extraction chamber center has a turntable and a series of wheel installed in parallel on the shaft, wheel and static ring of the upper and lower, respectively, are two clear room. And other extraction columns, light and heavy phase respectively at work from the bottom and the top of the tower to turntable and the extraction tower. 。 。







( Cover: rotary extraction tower principle and characteristics of the product)







rotary extraction tower belongs to the mechanical stirring extraction tower, referred to as RDC, it consists of belt of vertical cylinder horizontal static ring baffle. Static ring baffle as the center hole plate, static ring baffle cylinder can be divided into a series of extraction, extraction chamber center has a turntable and a series of wheel installed in parallel on the shaft, wheel and static ring of the upper and lower, respectively, are two clear room. Like other extraction columns, light and heavy phase respectively at work from the bottom and the top of the tower to rotary, contact in two-phase countercurrent extraction tower, under the action of turntable, the dispersed phase formation of small droplets, increase the mass transfer area of two phases. Finishes the extraction process of light and heavy phase respectively by top and bottom.

RDC can be used for all 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, RDC can also be used for mass transfer or no mass transfer by chemical reaction. One, the working principle of the rotary table extraction tower belongs to the mechanical stirring extraction tower equipment, it consists of three parts: the clarification section, the mixed section, under the clarification section. Which mixed section is a cylinder shape, internal by 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 phase ( Water phase) And the light phase ( Organic phase) From the top and bottom to enter respectively, in the tower countercurrent contact. Under the fixed wheel agitation, the dispersed phase formation of small droplets, increase the mass transfer area, after completing the process of extraction, light and heavy phase respectively from the top and bottom out. Second, the characteristics of overview of 1. Cover an area of an area small, low maintenance cost;
    2. Processing capacity big, suitable for continuous production;
    3. High grade efficiency. Three, application field
1. Biological engineering ( Nutrient solution, interferon, organic acid in the fermented liquid extraction)
    2. The food industry, Cooking oil, food, pigment, additives such as extraction)
    3. The environmental protection industry ( Sewage recycling, etc. ) Four, technical parameters,

note: materials such as glass, stainless steel 304, 316 stainless steel.
the above parameters are commonly used for the experimental parameters, specific application can be separately designed according to customer demand production. Five, the foreign latest developed a new extraction tower without mixing plant extraction tower, it is through an inert gas ( Or air) ACTS as a medium of two-phase hybrid mass transfer, and in the contact surface produces a mass transfer area, and has a great contact area, so the compared with the traditional extraction tower sieve plate extraction tower, packed extraction tower such as greater mass transfer efficiency, and can complete the extraction operation.

the specific structure and the principle stated as follows: it is a cylindrical device, two phase materials, respectively, from either side of the container into the container inside, and heavy phase next, equivalent to a countercurrent process, evenly spaced at the bottom of the container lined with gas generator ( Set aside a certain length of clarification area) Continuous injection of gas, and to the container, when the bubble upward movement, in contact with the two phase materials, produce mass transfer area, mass transfer finished, two phase, respectively, to reverse direction, and into the next mass transfer area. In the end, two phase respectively from each end. Gas recycling use.
