Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current filtration technologies for removing pollutants from flue gases, such as sulfur oxides and mercury vapor, face challenges in reducing manufacturing costs while maintaining or improving filter performance and accommodating various application geometries.
Innovation Solution
A filtration module comprising a filter member and a spacing member, where the filter member and spacing member are disposed in detached contact engagement to define concentric filtration and spacing layers, with the spacing member being elastically deformable to apply radially-inward and outward forces, facilitating gas flow and contact with the filter member without physical interconnections, and made from materials resistant to acid exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional filtration modules with physical interconnections are used, then structural stability is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The filtration module is divided into discrete layers (filtering layer, spacing layer, reinforcement layer) that are stacked alternately to form a modular structure. Each layer can be manufactured and assembled independently, reducing overall manufacturing complexity while maintaining structural stability through the layered configuration.
Solution Approach 2:
The spacing layer is positioned between filtering layers in a nested arrangement, with each spacing layer fitting within the structure defined by adjacent filtering layers. This nested configuration provides structural support and stability without requiring additional external framing or complex interconnections.
2Reliability
If filters are designed for specific geometries, then performance for that application is improved, but adaptability to other applications decreases
Solution Approach 1:
The filtration module employs standardized layer configurations and connection mechanisms that can be adapted to various geometries and applications. The alternating stack of filtering, spacing, and reinforcement layers creates a universal structure that maintains performance across different installation configurations and application scenarios.
3Ease of manufacture
If manufacturing processes are simplified, then production cost is reduced, but manufacturing precision may deteriorate
Solution Approach 1:
The spacing layer and reinforcement layer structures are designed to self-align and self-support during assembly. The geometric interlocking between layers and the inherent rigidity of the reinforcement elements provide automatic positioning, ensuring manufacturing precision without requiring complex alignment procedures or additional manufacturing steps.

Implementation Method 1
the spacing member being elastically deformable to apply radially-inward and outward forces
Implementation Method 2
pollutants are removed by modules, which contain a microporous adsorbent material (i.e., sorbent) held within a polymer matrix. The mercury vapor is removed from flue gas by chemically adsorbing Hg vapors

AI summary
A filtration module is provided that includes a filter member and a spacing member disposed in detached, contact engagement along a length of each member, such length extending about a longitudinal axis of a filtration module to define a concentric and detached plurality of filtration layers, and an interleaved, concentric and detached plurality of spacing layers, respectively. One or both of the plurality of spacing layers and plurality of filtration layers may provide a radially-inward directed force. The spacing member may be elastically deformed in the filtration module to apply a radially-inward directed force and a radially-outward directed force, wherein the filtration and spacing layers are retained in substantial fixed spatial relation. A retaining member may be located to engage an external side surface of the filtration module. A filtration module may be constructed by winding the filter member and spacing member about a longitudinal axis of the module.
