Media Holding Module With Contoured Inlet And Flexible Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media holding modules in air filtration systems suffer from inefficient airflow due to turbulence and resistance, dead flow zones, poor sealing, and inadequate utilization of filtration media, leading to reduced filtration efficiency and increased pressure drops.
Innovation Solution
A media holding module with a contoured inlet and perforated 'V'-shaped wall panels that reduce airflow resistance and turbulence, along with a flexible sealing system and support members outside the airflow path, allowing for multiple discrete layers of filtration media and improved sealing to prevent air bypass.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional flat box-like module design is used, then manufacturing is simple, but airflow turbulence and resistance increase
Solution Approach 1:
The patent applies curvature by replacing the traditional flat box-like inlet with a contoured, curved inlet design. This curvature smooths airflow transitions, reduces turbulence, and decreases resistance while maintaining manufacturing feasibility through standard forming processes for metal or plastic panels.
2Productivity
If media is held in discrete layers, then filtration efficiency improves, but device complexity increases
Solution Approach 1:
The patent divides the media holding space into multiple discrete layers or zones within the module. Each layer can contain different media types or configurations, allowing optimized filtration for specific contaminants while maintaining a standardized module exterior for easy installation and manufacturing.
3Strength
If support members are inside airflow path, then structural support is adequate, but pressure drop increases
Solution Approach 1:
The patent extracts support members from the airflow path and relocates them to the module exterior or walls. This allows adequate structural support to be maintained while eliminating obstructions that cause pressure drops and turbulence within the airflow path.
4Ease of operation
If sealing between module and duct is poor, then installation is easier, but air bypass increases
Solution Approach 1:
The patent incorporates flexible sealing elements such as gaskets or sealing films between the module and duct. These flexible components accommodate installation tolerances and maintain effective sealing without requiring precision installation, preventing air bypass while keeping installation relatively simple.

AI summary
A media holding module to hold various granular and pelletized gas phase filtration media for filtering air. The module is comprised of two solid side plates, and a perforated end panel and four perforated wall panels disposed between the side plates. The perforated wall panels are arranged in a generally “V”-shaped configuration. The interior wall panels are contoured at the module inlet to provide aerodynamic airflow. Additionally, the interior wall panels are perforated across their entire surface areas to allow for airflow access to all filtration media in the filtration media beds. The compartment created by the wall panels may be subdivided to form sub-compartments capable of holding discrete beds of filtration media in series. The module's support members are located outside of the air stream to avoid airflow resistance and turbulence. The module further includes a flexible, reversible sealing system for sealing the module in the module housing in various configurations while preventing air bypass. The module can be used to filter other gases and/or fluids.
