Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adsorption devices for compressed gas using granular adsorbents face issues such as dust formation, reduced drying capacity, and structural failure due to fluidisation and thermal shocks, leading to inefficiencies and equipment failure.
Innovation Solution
The use of a monolithic supporting structure with a coating containing an adsorbent, which prevents grain movement and fluidisation, allowing for higher gas flow rates and preventing dust formation, and is designed to maintain structural integrity under high humidity and temperature conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If granular adsorbent is used in conventional adsorption devices, then the device can achieve drying function, but dust formation occurs and drying capacity is reduced due to grain movement and fluidisation
Solution Approach 1:
The patent employs a monolithic porous supporting structure with integrated adsorbent coating instead of loose granular adsorbent. The porous structure provides high surface area for adsorption while maintaining structural integrity, preventing dust formation and fluidisation issues associated with granular materials.
Solution Approach 2:
The invention creates a composite structure combining a monolithic supporting structure (ceramic, metal, or polymer) with a coating layer containing the adsorbent material. This composite design provides both mechanical strength to prevent structural failure and adsorption functionality, eliminating the problems of grain movement and dust generation.
2Productivity
If high gas flow rates are used to increase productivity, then output improves, but structural failure occurs due to fluidisation and thermal shocks in granular systems
Solution Approach 1:
The monolithic porous supporting structure is designed to withstand high gas flow rates without fluidisation. The interconnected porous network allows high velocity gas flow while the solid monolithic structure prevents the structural failure and dust generation that occur in granular systems under similar conditions.
Solution Approach 2:
The composite construction of monolithic support with adsorbent coating creates a structurally robust system that can handle high flow rates and thermal shocks. The monolithic base provides mechanical strength while the coating maintains adsorption performance under demanding operating conditions.
3Duration of action of stationary object
If multiple vessels are used to enable continuous drying operation, then continuity is achieved, but device complexity increases
Solution Approach 1:
The monolithic supporting structure is divided into multiple segments or zones along the gas flow direction, with each segment containing adsorbent coating. This segmentation allows different zones to perform different functions (drying, regeneration) simultaneously, enabling continuous operation within a single integrated device rather than requiring multiple separate vessels.
Solution Approach 2:
The monolithic structure with zoned adsorbent coating serves multiple functions within a single device - simultaneous drying and regeneration zones, eliminating the need for multiple separate vessels. This multi-functional design achieves continuous operation while reducing overall device complexity.
