Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional drying bed configuration is used with deliquescent agents, then dehydration function is provided, but deliquescent agent consumption is high and dehydration performance is insufficient
Solution Approach 1:
The drying bed is segmented into multiple layers: a lower inert material layer (height h) and an upper deliquescent agent layer (height H). This segmentation allows the brine to flow through both layers sequentially, enabling the inert layer to contribute to dehydration and extend the useful life of the deliquescent agents, thereby reducing agent consumption while maintaining dehydration performance
Solution Approach 2:
The inert material layer acts as an intermediary between the effluent and the deliquescent agents. It provides a support structure that allows brine to flow through while maintaining contact with the deliquescent agents, optimizing the dehydration process and reducing the need for excessive deliquescent agent material
2Productivity
If the height of inert bed is increased to optimize brine flow, then dehydration efficiency improves, but the ratio of inert material to deliquescent agents increases leading to higher material usage
Solution Approach 1:
The invention optimizes the h/H ratio parameter within specific ranges (0.1 to 0.4) to achieve the best balance between dehydration efficiency and material usage. By controlling this parameter, the system maximizes the utilization of both inert material and deliquescent agents without excessive consumption of either component
