Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If activated carbon filter is used to purify regenerated lean liquid, then organic substances and suspended particles can be adsorbed, but heat-stable salts, high molecular weight degradation products, and metal ions cannot be completely removed
Solution Approach 1:
The purification system is segmented into multiple functional stages: activated carbon filtration for organic substances, followed by advanced oxidation processes and membrane separation for heat-stable salts and degradation products. Each stage targets specific pollutant types, achieving comprehensive purification that a single activated carbon filter cannot accomplish.
Solution Approach 2:
The invention employs composite purification technologies combining activated carbon with advanced oxidation catalysts and membrane materials. This composite approach enables simultaneous removal of diverse pollutants including heat-stable salts, high molecular weight degradation products, and metal ions through multiple mechanisms acting in sequence.
2Reliability
If packing in activated carbon filter is replaced when adsorption capacity decreases, then purification effectiveness can be maintained, but the replacement process is complex and requires stopping the machine
Solution Approach 1:
The system transitions from static packing to dynamic replaceable modules. The purification packing is designed as modular cartridges that can be quickly swapped without shutting down the system, enabling continuous operation while maintaining purification effectiveness through simple module replacement rather than complex packing procedures.
Solution Approach 2:
Spares packing modules are pre-prepared and can be quickly installed to replace exhausted ones. This preliminary preparation of replacement modules eliminates the need for complex on-site packing procedures and allows rapid module swapping during scheduled maintenance windows without requiring system shutdown.
3Quantity of substance
If the uppermost layer of packing fails first and lowermost layer fails last, then adsorption capacity decreases from top to bottom, but replacing packing requires removing all packings which increases workload
Solution Approach 1:
The packing is segmented into multiple independent modular cartridges arranged in series. When the uppermost layer shows signs of failure, only that specific module needs replacement rather than the entire packing bed. This segmentation allows targeted maintenance that preserves operational productivity by leaving functional modules in place.
Solution Approach 2:
The problematic packing module is extracted and removed individually from the system for replacement, while the remaining functional modules stay in place. This selective extraction approach eliminates the need to remove and replace all packings, significantly reducing maintenance workload and maintaining system productivity during replacement operations.
4Reliability
If multiple purification technologies are adopted according to solvent properties, then purification level can be improved, but device complexity increases
Solution Approach 1:
The purification system is designed with multi-functional integrated units that can handle different pollutant types through a single modular platform. The universal module design incorporates multiple purification mechanisms (adsorption, oxidation, separation) within each cartridge, allowing high purification levels without proportionally increasing overall system complexity.
Solution Approach 2:
The system employs dynamically configurable modular modules that can be selectively activated based on solvent properties and pollutant composition. This dynamic adaptability allows the system to achieve high purification levels for specific applications without always deploying the full complexity of all available purification technologies.

AI summary
Provided are a drawer-type carbon capture solvent purification and recovery device and method. The recovery device includes a support, a mounting frame and a purification module, the purification module is connected in an insertable manner to the mounting frame along the outer periphery of the mounting frame at equal intervals, and two adjacent purification modules are communicated with each other. The left half of the mounting frame forms a purification region, and the right half of the mounting frame forms a regeneration region. A liquid to be filtered sequentially flows through all purification modules in the purification region from top to bottom and then is discharged from a liquid outlet pipe. When the packing of the uppermost purification module in the purification region fails, the mounting frame is rotated, so that the failed purification module is rotated to the regeneration region, and the lowest purification module in the regeneration region is rotated to the purification region accordingly.
