Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flow conditioners for gas transport pipes are ineffective in eliminating swirl, asymmetry, and pulses in gas flow, especially in compact stations, and risk clogging of porous plates leading to interruptions in gas feed continuity.
Innovation Solution
A compact flow conditioner with a tubular main body, a flow rectifier, and a porous plate, featuring a bypass circuit to ensure continuous fluid flow if the porous plate becomes clogged, utilizing a magnetic attraction system to hold the moving element in place and allow axial translation to open a bypass passage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a porous plate is added to improve flow homogenization, then flow disturbance attenuation is improved, but the risk of clogging increases
Solution Approach 1:
The flow conditioner is divided into multiple functional sections: a porous plate for flow homogenization, a flow rectifier with multiple holes for disturbance attenuation, and a bypass circuit with opening/closing elements. This segmentation allows each component to perform its specific function while providing alternatives if one component fails (clogging), thus resolving the contradiction between improved flow conditioning and clogging risk.
Solution Approach 2:
The bypass circuit with opening/closing elements is designed in advance to compensate for potential clogging of the porous plate. When clogging occurs, the bypass circuit can be activated to maintain flow continuity. This prior cushioning approach ensures that the system maintains reliability even when the porous plate becomes clogged, resolving the contradiction between using porous plates for flow homogenization and the inherent clogging risk.
2Object-affected harmful factors
If flow conditioners are designed with long straight lines upstream and downstream, then flow disturbance attenuation is improved, but the device complexity and space requirements increase
Solution Approach 1:
The invention merges multiple flow conditioning functions (flow homogenization through porous plate, flow rectification through multiple rectifier elements, and bypass capabilities) into a single integrated device. This combination eliminates the need for long straight lines upstream and downstream, as all necessary conditioning occurs within the compact conditioner itself, thus resolving the contradiction between effective flow disturbance attenuation and reduced device complexity/space requirements.
Solution Approach 2:
The flow conditioner acts as an intermediary device that creates artificial flow conditioning without requiring long natural straight lines. The porous plate, flow rectifier, and bypass circuit work together as intermediary elements to achieve flow homogenization and disturbance attenuation in a compact configuration, resolving the contradiction between effective flow conditioning and space requirements.
3Volume of moving object
If the porous plate is made more compact, then the device size is reduced, but the effectiveness in reducing swirl and asymmetry decreases
Solution Approach 1:
The flow rectifier is designed with multiple holes distributed at different locations and orientations to address specific local flow disturbances. This local quality approach ensures effective reduction of swirl and asymmetry in different regions of the flow, maintaining effectiveness while keeping the overall device compact, thus resolving the contradiction between compact size and disturbance reduction effectiveness.
Solution Approach 2:
The flow rectifier uses three-dimensionally oriented holes and the bypass circuit operates in a parallel dimension to the main flow path. This dimensional approach allows effective flow conditioning in a compact volume by utilizing spatial arrangements and parallel flow paths, resolving the contradiction between compact size and effectiveness in reducing swirl and asymmetry.

Function Achieved in This Case
Effectively attenuates flow disturbances while maintaining gas feed continuity by allowing a bypass passage when the porous plate clogs, ensuring accurate metering and reducing noise levels.
Implementation Method 1
The presence of a porous plate in the conditioner is particularly advantageous since it makes it possible significantly to improve the homogenizing ability of the perforated plate on the flow
Implementation Method 2
the moving element being in contact with the stationary element in the absence of the porous plate becoming clogged

AI summary
The flow conditioner for a fluid transport pipe, comprises a support-forming substantially tubular main body, at least one flow rectifier disposed inside the main body essentially perpendicularly to the axis XX′ thereof, and a porous plate disposed inside the main body upstream from the flow rectifier and parallel thereto. The elements of the conditioner are disposed in such a manner that a substantial fraction of the fluid flow passes through the flow rectifier and the porous plate in the absence of the porous plate becoming clogged. A bypass circuit is provided to ensure fluid flow continuity in the event of the porous plate becoming clogged.
