Modular Weir for Coalescing Separator Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coalescing separators face challenges in efficiently separating oil from coolant liquids in smaller systems, as the permanent attachment of weir mechanisms makes it difficult to adjust and maintain the separation process, and they are not adaptable to various fluid levels and tank sizes.
Innovation Solution
A modular weir system is introduced, which includes a weir front wall higher than the weir middle wall, allowing fluid to flow under and over the weir, and can be easily detached and replaced, enabling adjustable separation and cleaning without affecting the entire apparatus, and is compatible with various tank dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If weir walls are permanently affixed to the coalescing separator apparatus, then structural stability is improved, but adaptability to different tank sizes and fluid levels deteriorates
Solution Approach 1:
The weir mechanism is divided into separate modular components (weir front wall, weir middle wall, weir back wall, and weir side walls) that can be detached and reconfigured. This segmentation allows the same components to be adapted to different tank sizes and fluid levels while maintaining structural integrity through proper coupling mechanisms.
2Strength
If weir walls are permanently welded or molded to the apparatus, then manufacturing strength is improved, but ease of maintenance and cleaning deteriorates
Solution Approach 1:
The weir is constructed as detachable modular walls rather than a permanently welded structure. The coupling mechanisms allow for strong assembly during operation while enabling easy disassembly for maintenance and cleaning, resolving the contradiction between manufacturing strength and ease of repair.
3Manufacturing precision
If the weir mechanism is designed with fixed wall heights, then manufacturing precision is improved, but adaptability to various fluid levels deteriorates
Solution Approach 1:
The weir system incorporates adjustable wall heights through detachable modular components. Different combinations of weir front wall, weir middle wall, and weir back wall segments can be assembled to create varying effective heights, allowing adaptation to different fluid levels while maintaining manufacturing precision for each individual component.
4Ease of manufacture
If the weir walls are spaced far apart, then ease of manufacturing is improved, but difficulty of attachment deteriorates
Solution Approach 1:
Coupling mechanisms serve as intermediaries between the weir walls and the containment well. These coupling mechanisms simplify the attachment process by providing standardized connection points, making it easier to assemble the weir components at appropriate spacings without increasing overall device complexity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The modular weir system allows for efficient separation of oil from water, enables fine control of the oil level removed, and minimizes downtime for maintenance, as it can be easily cleaned and swapped, accommodating different fluid levels and tank sizes without the need for permanent attachment.
Implementation Method 1
allowing the oil to coalesce from the water stream and form a surface layer of oil
Implementation Method 2
The weir middle wall extends to a bottom of the modular weir and the front wall does not extend to the bottom of the modular weir, whereby a path is configured for fluid to flow under the weir front wall and over the weir middle wall

AI summary
In an embodiment, a coalescing separator apparatus includes a containment well configured to include a coalescing media an inlet on a first end wall and an outlet on a second end wall; a surface-skimming drain disposed in the containment well; and a modular weir comprising a weir front wall, a weir middle wall, and a weir back wall, each of which are coupled to two opposing weir side walls, a through-hole being disposed in the weir back wall, through which the outlet is disposed. A modular weir and method for quickly replacing, maintaining, or repairing a weir in a coalescing separator apparatus is also described.
