Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If conventional emulsion demulsifying apparatus is used to separate floating matter from processing liquid, then floating matter can be removed, but high specific gravity liquid is discarded together with low specific gravity liquid causing waste
Solution Approach 1:
The separation tank is divided into multiple compartments: a first separation chamber for floating matter separation, a second separation chamber for high specific gravity liquid separation, and a settling chamber. This segmentation allows different types of substances to be separated in different zones, enabling recovery of high specific gravity liquid while removing floating matter.
Solution Approach 2:
A partition wall with a specific opening position is introduced as an intermediary structure between the first and second separation chambers. The opening position of the partition wall controls the separation interface, allowing high specific gravity liquid to accumulate in the second chamber while preventing it from being discharged with the floating matter in the first chamber.
2Productivity
If microbubble generator is used to enhance demulsification, then separation efficiency is improved, but device complexity and operational complexity increase
Solution Approach 1:
A microbubble generator is integrated into the system to inject fine bubbles into the processing liquid. The microbubbles attach to floating matter and facilitate its separation. The use of pneumatic bubble generation enhances demulsification efficiency without requiring complex mechanical separation mechanisms.
Solution Approach 2:
The system changes the physical parameter of the gas phase by generating microbubbles with specific size distribution. These microbubbles have different rise velocities and attachment characteristics compared to large bubbles, improving the efficiency of floating matter separation while maintaining simple device structure.
3Manufacturing precision
If simple separation system is used, then device complexity is reduced, but separation precision and recovery efficiency decrease
Solution Approach 1:
The tank is segmented into functionally distinct chambers: a first separation chamber for floating matter, a second separation chamber for high specific gravity liquid, and a settling chamber. This segmentation achieves precise separation of different substances while maintaining a relatively simple overall tank structure.
Solution Approach 2:
A partition wall with a controlled opening serves as an intermediary structure that enables precise separation. The opening position of the partition wall is specifically designed to allow high specific gravity liquid to pass to the second chamber while preventing mixing with floating matter, achieving high separation precision without complex mechanisms.
