Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple honeycomb structure is used, then the device complexity is reduced, but the gas flow uniformity deteriorates causing central region flow dominance and peripheral region flow difficulty
Solution Approach 1:
The invention segments the honeycomb structure by introducing communication pore groups that divide and redirect gas flow paths. These communication pores create additional flow channels that segment the dominant central flow into distributed paths, enabling gas to reach peripheral regions more effectively and achieving uniform flow distribution without complex structural modifications.
Solution Approach 2:
The communication pore group acts as an intermediary element within the honeycomb structure. It mediates between the main gas inlet and the peripheral cells by providing intermediate flow paths through the partition walls, allowing gas to progressively reach peripheral regions and balance the flow distribution across the entire structure.
2Quantity of substance
If the honeycomb structure diameter is increased or multiple structures are arranged, then the recovery capacity is improved, but the flow uniformity deteriorates and peripheral region adsorbent performance decreases
Solution Approach 1:
By segmenting the flow paths through communication pores distributed across the honeycomb structure, the invention enables large-diameter or multi-structure reactors to maintain uniform flow distribution. The communication pores create multiple parallel flow segments that prevent flow dominance in central regions, ensuring all adsorbent surfaces are effectively utilized even at large scales.
Solution Approach 2:
The invention applies local quality by positioning communication pore groups at specific locations within the honeycomb structure to address local flow distribution issues. This targeted approach modifies flow characteristics in specific regions without requiring complete structural redesign, maintaining overall system capacity while improving peripheral flow uniformity.
3Productivity
If adsorbent is supported on partition walls, then the CO2 recovery function is achieved, but the adsorbent deteriorates unevenly with central region adsorbent degrading faster, reducing reactor lifespan
Solution Approach 1:
The communication pore group segments the gas flow to distribute it uniformly across all partition walls, preventing concentration of flow and adsorption stress in central regions. This segmentation ensures even utilization and aging of adsorbent throughout the structure, extending reactor lifespan while maintaining recovery productivity.
Solution Approach 2:
By creating uniform flow distribution through communication pores, the invention achieves homogeneous adsorbent utilization across the entire honeycomb structure. All adsorbent regions experience similar flow conditions and degradation rates, preventing the uneven aging that previously occurred with central region dominance and extending overall system durability.
