DMF Recovery Tower

In the DMF recovery tower equipment, the liquid phase undergoes multiple dispersion and aggregation processes. During this process, the liquid is ejected as very fine droplets from a rotating coil arranged in concentric circles. Under the force of centrifugal force, the high-speed moving droplets collide, shear, and splash against specific structures within the equipment, forming a large gas-liquid interface. After collection, they enter the next cycle.

In the unit, the gas-liquid two-phase flow is generally countercurrent in the rotor. The gas-liquid contact process within the annular gaps of the internal structure of the equipment can be divided into two steps: one is when the liquid phase is ejected from the center, it comes into crossflow contact with the gas; the other is the process where the liquid phase falls down along the specific structural wall of the equipment. In the annular gap, the gas rotates upwards, while the liquid moves downwards under the influence of the gas and gravity, forming a countercurrent contact.
