Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carbon dioxide adsorption devices face inefficiencies in residence time and heat exchange during desorption, leading to reduced energy utilization and poor desorption effects due to short gas residence time and incomplete material contact.
Innovation Solution
A packing device with a heating support frame, packing layer support, and specially structured packing cells that alternate in length and orientation, creating a staggered arrangement to increase turbulence and residence time of thermal fluid, ensuring full contact with adsorption material for enhanced heat exchange and desorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If thermal fluid flows through the heating support frame, then heat exchange occurs with the packing material, but the residence time is too short for complete material contact
Solution Approach 1:
The packing cells are designed with curved, non-linear flow paths that force the thermal fluid to traverse a longer, serpentine route through the packing material. This curved path configuration increases the residence time of the thermal fluid within the heating support frame, allowing more complete heat exchange and material contact while maintaining efficient heat transfer through the optimized curvature of the flow channels.
2Duration of action of moving object
If packing cells are arranged in a simple linear pattern, then device structure is simple, but turbulence and residence time are insufficient
Solution Approach 1:
The packing cells are arranged in an asymmetric, staggered pattern rather than a simple linear or grid configuration. This asymmetric arrangement creates flow path variations and turbulence zones that extend the residence time of the thermal fluid, while the modular nature of the asymmetric pattern keeps the device structure manageable and manufacturable.
3Productivity
If thermal fluid flow speed is high, then productivity is improved, but heat exchange completeness deteriorates
Solution Approach 1:
The curved flow paths created by the packing cell configuration naturally reduce flow velocity through increased path length and turbulence, allowing high productivity to be maintained while ensuring complete heat exchange. The serpentine flow pattern created by the asymmetric arrangement dissipates kinetic energy and promotes thorough mixing and contact between the thermal fluid and packing material.
