Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional trickle-down configurations are used for stripping/desorption, then the device can achieve target component separation, but the device requires large volume and consumes excessive energy
Solution Approach 1:
The patent applies the dynamics principle by replacing the static trickle-down configuration with a dynamic rotating rotor system. The rotor rotates at controlled speeds to create centrifugal forces that distribute the solvent film uniformly across the channel walls, enhancing mass transfer efficiency. This dynamic approach allows the system to achieve superior extraction efficiency while reducing the required device volume and energy consumption compared to conventional static configurations.
Solution Approach 2:
The patent utilizes parameter changes by varying the rotational speed of the rotor to optimize the centrifugal force applied to the solvent. By controlling the rotation speed, the system can adjust the solvent film thickness and residence time, thereby optimizing the stripping efficiency. This parameter control enables the system to achieve high extraction efficiency with reduced energy input and smaller device footprint.
2Productivity
If conventional trickle-down configurations are used for stripping/desorption, then the device can achieve target component separation, but the device occupies large space
Solution Approach 1:
The rotating rotor creates dynamic centrifugal forces that intensify the mass transfer process within a compact volume. The rotation generates sufficient centrifugal acceleration to enhance solvent-gas contact efficiency, allowing the system to achieve high extraction productivity in a much smaller device volume compared to conventional trickle-down configurations that require large vertical columns.
Solution Approach 2:
The patent transitions from a vertical trickle-down configuration to a rotational system that utilizes centrifugal force in the radial direction. This dimensional change allows the mass transfer process to occur more efficiently in a horizontal plane, reducing the vertical height and overall volume of the device while maintaining or improving extraction productivity.
