Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adsorption systems face inefficiencies in adsorbing gas components when humidity is high, as adsorbent materials tend to adsorb water vapor, reducing their capacity for other gases, leading to decreased adsorption efficiency.
Innovation Solution
An adsorption system that includes a measurement unit to assess humidity and a flow rate controller to adjust the gas flow rate based on humidity levels, optimizing the adsorption of both the target gas component and water vapor, thereby enhancing adsorption efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the adsorbent material adsorbs water vapor, then the adsorbent material can remove water vapor from the gas, but the amount of gas other than water vapor that the adsorbent material can adsorb decreases
Solution Approach 1:
The patent applies dynamics by making the gas flow rate adjustable based on humidity conditions. The flow rate controller dynamically changes the gas flow rate through the adsorption part according to measured humidity levels, optimizing the balance between water vapor removal and target gas adsorption efficiency
Solution Approach 2:
The patent changes the operational parameter (gas flow rate) based on humidity conditions. When humidity is high, the gas flow rate is increased to prevent excessive water vapor adsorption, thereby maintaining adsorption capacity for the target gas component
2Productivity
If the gas flow rate is increased, then the adsorption capacity for target gas may improve, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts the gas flow rate based on real-time humidity measurements, increasing flow rate only when necessary (high humidity conditions) to maintain adsorption efficiency, rather than operating at high flow rate continuously
Solution Approach 2:
The gas flow rate parameter is changed adaptively based on humidity levels, optimizing the trade-off between adsorption efficiency and energy consumption by using higher flow rates only when required
