Condensate Separator Shielding Housing Flow Ribs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing condensate separators experience frequent actuation of the condensate drain valve due to strong fluctuations in the liquid level caused by the influence of compressed air flowing above the shielding housing, leading to undesirably frequent operation.
Innovation Solution
The introduction of flow damming ribs on the outer surface of the shielding housing, which calms the compressed air flow and reduces cyclic rocking movements of the condensate, ensuring the condensate drain valve operates based solely on the actual water level, not temporary peaks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If passage windows are provided in the shielding housing to allow condensate entry, then condensate can be collected inside the shielding housing, but compressed air flow influences the actuating device causing frequent valve actuation
Solution Approach 1:
The shielding housing is segmented into multiple annular gap segments by the flow damming ribs, which divide the single large passage window into several smaller segments. This segmentation reduces the direct influence of compressed air flow on the actuating device while still allowing condensate to enter through the distributed segments.
Solution Approach 2:
The flow damming ribs act as intermediary elements between the compressed air flow and the actuating device. These ribs create a flow-calming effect that mediates the interaction between the compressed air and the actuating mechanism, reducing harmful fluctuations while maintaining condensate passage.
2Productivity
If compressed air flows freely around the shielding housing, then air flow resistance is minimized, but condensate experiences cyclic rocking movements causing false level readings
Solution Approach 1:
The annular gap is segmented into multiple smaller gaps by the flow damming ribs arranged circumferentially. This segmentation creates individual flow channels that restrict turbulent motion while maintaining overall air flow efficiency, thereby stabilizing the condensate liquid level.
Solution Approach 2:
The flow damming ribs create localized flow restriction zones at specific circumferential positions without completely blocking the annular gap. This local quality approach allows air to flow efficiently while creating sufficient resistance to prevent condensate rocking movements that would cause false level readings.
3Reliability
If flow damming ribs are added to the shielding housing, then compressed air flow is calmed and valve actuation is reduced, but device complexity increases
Solution Approach 1:
The flow damming ribs are integrally formed with the shielding housing as a single molded piece rather than being separate components. This merging of functions reduces assembly complexity and manufacturing steps while achieving the desired flow calming effect for reliable valve actuation.
Solution Approach 2:
The flow damming ribs serve multiple functions simultaneously: they act as flow restrictors to calm compressed air, provide structural support for the shielding housing, and create the necessary flow channels for condensate entry. This multi-functionality reduces the need for additional components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This results in low-interference operation of the condensate drain valve, minimizing unnecessary actuations and improving the separation quality by reducing the re-enrichment of compressed air with liquid particles.
Implementation Method 1
the flow damming ribs cause a local damming of the compressed air flow entering the annular gap between the shielding housing and the side wall of the chamber
Implementation Method 2
The swirl generating device works according to the centrifugal principle and imparts a swirl to the compressed air flowing through it, so that it is caused to rotate and liquid particles contained in it are separated due to centrifugal force
Implementation Method 3
The separated liquid particles run down the inner surface of the chamber side wall delimiting the collecting chamber, so that the separated condensate collects in the lower end section of the collecting chamber

AI summary
A condensate separator (1) is proposed, comprising a collection chamber (14) for separated condensate, in the upper part of which a swirl-generating device (7) is arranged, and in the lower part which contains a condensate drain valve (28) enclosed by a shielding housing (36). The shielding housing (36) has a housing side wall (38) provided with passage windows (47) through which the condensate can pass. To reduce flow influences, the shielding housing (36) has several radially projecting flow-impacting ribs (57) distributed around its circumference on the outside of the housing side wall (38).
