Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional filter devices for machines like gas turbines face efficiency decreases due to particle accumulation, leading to increased pressure drop and the need for costly steel construction, with filter replacements requiring machine shutdown.
Innovation Solution
A filter device with a filter housing featuring air-permeable media that filters multi-directional airflow, offering a larger surface area, reduced pressure loss, and longer filter life, potentially made from glass-fiber or polymer materials, and incorporating a vibration system to remove accumulated particles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional filters are used to remove particles from airflow, then filtration is achieved, but pressure drop increases and efficiency decreases
Solution Approach 1:
The filter housing is configured to allow multi-directional airflow through a substantial portion of its surface area, rather than forcing all air through a single restricted inlet. This dimensional approach distributes airflow across multiple paths, reducing pressure drop while maintaining particle removal effectiveness
Solution Approach 2:
The filter housing incorporates air-permeable filter media that allows airflow through its structure. This porous configuration enables particles to be captured while air passes through, reducing the resistance and pressure drop compared to conventional solid filter designs
2Reliability
If filters are used to capture particles, then air quality improves, but filter replacement requires machine shutdown
Solution Approach 1:
The filter housing is designed with a vibration system that automatically removes accumulated particles from the filter media during operation. This self-cleaning mechanism maintains filtration effectiveness without requiring shutdowns for manual maintenance, enabling continuous machine operation
Solution Approach 2:
The vibration system operates periodically to dislodge and remove accumulated particles from the filter media. This periodic cleaning action restores airflow characteristics and maintains filtration performance over extended periods without replacement
3Strength
If steel construction is used for filter housing, then structural strength is achieved, but cost increases
Solution Approach 1:
The filter housing design changes the structural parameters by using optimized geometries and alternative materials with appropriate strength-to-cost ratios. This allows reduction of manufacturing costs while maintaining sufficient structural integrity for the application
