Carbon Dioxide Recovery Modules with Staggered Shared Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional carbon dioxide recovery devices with a single large sorbent material require intermittent operation of equipment, leading to momentary large outputs and inefficient control of multiple modules.
Innovation Solution
The carbon dioxide recovery device is configured with a plurality of modules, where operation timings are staggered, and equipment like fans, heat sources, and vacuum pumps are shared, with the number of modules determined by the ratio of adsorption to desorption times, ensuring continuous operation and reduced equipment capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a single large sorbent material is used, then the equipment capacity can be reduced, but the operation becomes intermittent requiring momentary large outputs
Solution Approach 1:
The single large sorbent material is divided into multiple smaller sorbent materials arranged in parallel. Each sorbent material operates in its own cycle, allowing the system to maintain continuous operation while using smaller, more manageable equipment capacity for each unit.
2Power
If multiple modules are used with staggered operation, then equipment capacity can be reduced, but controlling the operation timings becomes complex
Solution Approach 1:
Each sorbent material operates in periodic cycles of adsorption and desorption. By staggering these periodic cycles across multiple sorbent materials, the system achieves continuous operation with smaller equipment capacity while the periodic nature provides a structured framework for control.
Solution Approach 2:
The control device manages multiple sorbent materials using a unified control strategy that applies to all modules. This universal approach simplifies control complexity by using the same control logic across different sorbent materials, despite their staggered operation timings.
3Productivity
If multiple modules are used, then operational continuity is improved, but the uniform distribution of output becomes difficult
Solution Approach 1:
The control device orchestrates periodic adsorption and desorption cycles across multiple sorbent materials. By carefully timing these periodic actions and staggering them appropriately, the system maintains continuous productivity while the control device ensures uniform distribution of operational load and output across all modules.
