Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heat transfer pipe is used to control temperature of the adsorbent, then the adsorbent near the pipe can be temperature-controlled, but heat transfer efficiency decreases in regions away from the pipe
Solution Approach 1:
The adsorbent bed is segmented into multiple regions by inserting flow channel forming plates with hole portions at regular intervals. This segmentation allows heat transfer pipes to be distributed throughout the adsorbent bed rather than concentrated in one location, enabling uniform temperature control across all regions while maintaining high heat transfer efficiency.
2Reliability
If heat transfer pipes are used for temperature control, then adsorption can occur, but temperature uniformity across the adsorbent bed deteriorates
Solution Approach 1:
Flow channel forming plates with hole portions are strategically positioned at specific locations within the adsorbent bed to create localized flow channels. This local modification directs gas flow and heat transfer to specific regions, ensuring uniform temperature distribution across the entire adsorbent bed while maintaining reliable adsorption performance.
3Ease of operation
If adsorbent is packed around heat transfer pipes, then temperature control is possible, but adsorption efficiency decreases due to poor heat transfer in away regions
Solution Approach 1:
The invention transitions from a one-dimensional heat transfer approach (pipes surrounded by adsorbent) to a three-dimensional heat transfer network by inserting flow channel forming plates with hole portions throughout the adsorbent bed. This dimensional expansion creates multiple heat transfer pathways in different directions, ensuring efficient heat and mass transfer throughout the entire adsorbent volume and significantly improving adsorption efficiency.
