Solution Overview
Problem
Existing gas adsorption/desorption technologies face challenges in uniformly heating gas adsorbents, leading to inefficient gas recovery, particularly in direct air recovery (DAC) methods for CO2 from air, due to inconsistent distribution of magnetic materials and the difficulty in introducing electrical conduction through thermally conductive filaments.
Innovation Solution
A gas adsorption/desorption unit incorporating honeycomb structures with integrated magnetic materials and gas adsorbents, where the magnetic material is present in radial and axial directions, allowing for uniform induction heating and efficient gas adsorption/desorption, enhanced by a magnetic shield and controlled distribution of magnetic and gas adsorbent components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If magnetic material is mixed with gas adsorbent in adsorbent container, then gas adsorption/desorption can be performed, but uniform heating of gas adsorbent cannot be achieved
Solution Approach 1:
The invention divides the adsorbent container into multiple independent honeycomb structures, each with its own flow paths. This segmentation allows for more uniform distribution of magnetic material and gas adsorbent within each cell, enabling consistent induction heating across the entire adsorbent bed while maintaining high adsorption/desorption efficiency.
Solution Approach 2:
The invention applies local quality by coating gas adsorbent on the inner surfaces of partition walls and introducing magnetic material specifically into cell cavities. This localized arrangement ensures that magnetic material is distributed uniformly throughout the structure, enabling consistent induction heating while maintaining high gas adsorption capacity on the partition wall surfaces.
2Temperature
If thermally conductive filaments are densely arranged in support, then uniform heating of adsorbent material can be achieved, but it becomes difficult to introduce electrical conduction
Solution Approach 1:
The invention replaces the mechanical system of thermally conductive filaments with an electromagnetic field-based induction heating system. By using induction heating coils to generate electromagnetic fields that directly heat the magnetic material and subsequently the gas adsorbent, the system achieves uniform heating without requiring complex networks of thermally conductive filaments or electrical conduction pathways.
3Productivity
If magnetic material and gas adsorbent are filled in adsorbent container, then gas recovery can be performed, but consistent distribution of magnetic material cannot be ensured
Solution Approach 1:
By dividing the container into multiple honeycomb structures with defined cells, the invention provides specific spaces for magnetic material placement. This segmentation enables consistent distribution of magnetic material throughout the adsorbent bed, ensuring uniform induction heating while maintaining high gas recovery efficiency through the large surface area of partition walls coated with gas adsorbent.
