Solution Overview
Problem
Conventional adsorptive bulk filters using small adsorber particles face high pressure loss and channel formation issues, leading to suboptimal adsorption efficiency and mechanical instability, while existing solutions with additional carriers or complex processing steps are inefficient and inflexible.
Innovation Solution
The development of adsorptive shaped bodies formed from agglomerates of adsorber particles connected via a thermoplastic organic polymer, allowing for reduced pressure loss and enhanced mechanical stability through a pressing process that maintains the adsorption efficiency and flexibility of the adsorptive structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If small adsorber particles are used in bulk filters, then adsorption efficiency is improved due to larger surface area, but pressure loss increases and channel formation occurs
Solution Approach 1:
The filter media is segmented into individual adsorber particles that are subsequently agglomerated into larger clusters. This segmentation allows the use of fine particles for high surface area while the agglomeration process creates larger effective particle sizes that reduce pressure loss and prevent channel formation, resolving the contradiction between adsorption efficiency and flow stability
Solution Approach 2:
The invention creates composite agglomerates by bonding adsorber particles together using thermoplastic organic polymers. These composite structures combine the high surface area of fine particles with the mechanical stability and flow characteristics of larger particles, achieving both high adsorption efficiency and reduced pressure loss simultaneously
2Reliability
If larger adsorber particles are used, then pressure loss is reduced, but adsorption efficiency decreases due to smaller surface area
Solution Approach 1:
The filter media is segmented into individual adsorber particles that are subsequently agglomerated into larger clusters. This segmentation allows the use of fine particles for high surface area while the agglomeration process creates larger effective particle sizes that reduce pressure loss and prevent channel formation, resolving the contradiction between adsorption efficiency and flow stability
Solution Approach 2:
The invention creates composite agglomerates by bonding adsorber particles together using thermoplastic organic polymers. These composite structures combine the high surface area of fine particles with the mechanical stability and flow characteristics of larger particles, achieving both high adsorption efficiency and reduced pressure loss simultaneously
3Strength
If additional carrier materials are used to support adsorber particles, then mechanical stability is improved, but device complexity and processing complexity increase
Solution Approach 1:
The invention extracts and eliminates the need for separate carrier materials by using the adsorber particles themselves as the structural framework. The thermoplastic polymer bonds directly to the adsorber particles, creating self-supporting agglomerates that maintain mechanical stability without requiring additional carrier structures, thus reducing device complexity
Solution Approach 2:
The adsorber particles serve dual functions: they provide the active adsorption surface area and they form the structural framework for mechanical stability. The thermoplastic polymer binds the particles together to create self-supporting agglomerates, eliminating the need for separate carrier materials and simplifying the overall device structure
4Strength
If adsorber particles are bonded into agglomerates, then mechanical stability and flexibility are improved, but adsorption surface area may be reduced
Solution Approach 1:
The thermoplastic polymer is applied locally at the contact surfaces between adsorber particles rather than coating the entire particle surface. This localized bonding provides mechanical stability and flexibility at the particle interfaces while preserving the adsorption surface area on the particle exteriors, resolving the contradiction between structural integrity and adsorption capacity
