(229f) Hydrodynamic Performance of Crossflow Concentric-Ring Rotating Bed

A new kind of high-gravity device—crossflow concentric-ring rotating bed is developed, the rotor of which contains a series of concentric rings. Its structures and flow channel arrangements determine its super features, such as low gas pressure drop and power consumption. The gas flow passes axially through the rotor and the liquid travels radially from the inside to the outside of the rotor. During this process, the gas flow repeatedly contacts cross-currently with the liquid flow between the concentric rings. This contact mechanism is favorable to gas-liquid stripping operation widely used in chemical process industries. In a pilot crossflow concentric-ring rotating bed, the pressure drop and the power consumption were measured under different operation conditions. The experimental results show it has lower gas pressure drop and power consumption.
