Adjustable Media Bed Sidewalls for Dry Scrubber Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dry scrubbing systems with fixed media bed volumes face limitations in adjustable media replacement schedules and increased energy usage due to non-alterable pressure drop, which affects the efficiency and cost-effectiveness of air filtration.
Innovation Solution
A deep bed scrubber with adjustable perforated sidewalls that allow for varying media bed volumes and surface area, enabling customizable media life and reduced pressure drop by sliding or angling the sidewalls along interior tracks, and a method for transferring filter media between media beds and containers using airflow obstruction and blower-powered vacuum.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed volume media beds are used in dry scrubbing systems, then the system structure is simple and reliable, but the media replacement schedule and pressure drop are non-adjustable, leading to increased energy usage and inability to optimize media life
Solution Approach 1:
The patent applies the dynamics principle by making the media bed volume adjustable through movable sidewalls that can be repositioned along tracks. This allows the system to adapt to different media replacement schedules and operational requirements. The sidewalls can be moved to change the volume of media beds, enabling flexible adjustment of media life and pressure drop characteristics without requiring a complete system redesign.
Solution Approach 2:
The patent segments the media bed into multiple compartments separated by movable sidewalls. Each compartment can be independently adjusted by moving the sidewalls to different positions along the tracks. This segmentation allows flexible configuration of media volumes in different sections, enabling optimized media replacement schedules and pressure drop management while maintaining a relatively simple overall structure.
2Use of energy by moving object
If fixed volume media beds are used, then the device complexity is low, but the pressure drop is non-alterable causing increased energy usage
Solution Approach 1:
The patent reduces energy usage by making the media bed volume dynamic and adjustable. Users can reposition the sidewalls to change media bed volumes, thereby optimizing pressure drop levels to match actual operational requirements. This flexibility allows the system to operate at lower energy consumption levels by adjusting media volumes to minimize unnecessary pressure drop, rather than being constrained by fixed bed configurations.
3Duration of action of moving object
If media bed volume is increased to extend media life, then media capture efficiency improves, but pressure drop increases leading to higher energy consumption
Solution Approach 1:
The patent resolves this contradiction by enabling dynamic adjustment of media bed volumes. Users can increase media volume in specific compartments to extend media life and improve capture efficiency, while simultaneously adjusting other compartments to maintain acceptable pressure drop levels. This flexibility allows optimization of both media life and energy consumption by distributing media volumes strategically across multiple compartments rather than uniformly increasing the entire bed.
Solution Approach 2:
The patent segments the media bed into multiple independently adjustable compartments. This allows selective increase of media volume in compartments where extended media life is prioritized, while keeping other compartments at lower volumes to minimize pressure drop. The segmentation enables fine-tuned optimization of the balance between media life and energy consumption based on specific operational requirements.
