Lamellar Separator Catch Basin Partitioning Against Droplet Entrainment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lamellar separators face issues with liquid droplets being swirled and entrained back into the separation space due to fluid stream immersion and upward lateral flows, leading to inefficient drainage and reduced thermal efficiency in power plants.
Innovation Solution
Incorporating a partition wall in the catch basin to divide it into multiple areas, which calms the liquid and prevents upward entrainment, along with corrugated lamellar profiles and undercut plates to enhance separation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the catch basin is left open without partition walls, then the fluid stream can flow freely through the separator, but the liquid in the catch basin is swirled and entrained by the fluid stream, causing droplets to be expelled back into the separation space
Solution Approach 1:
The catch basin is divided into multiple areas by partition walls, creating separate zones for liquid collection and fluid flow. This segmentation prevents the high-speed fluid stream from directly contacting and entraining the separated liquid, while still allowing the fluid to pass through the separator effectively.
Solution Approach 2:
The partition walls act as intermediary structures between the fluid stream and the collected liquid. They block the direct path of the fluid stream toward the liquid surface, preventing swirls and entrainment while allowing the fluid to flow around the partitions and continue through the separator.
2Productivity
If the fluid stream flows at high speed through the lamellar separator, then productivity is improved, but the fluid stream immerses into the catch basin and creates upward lateral flows that detach and expel droplets
Solution Approach 1:
By dividing the catch basin into multiple areas with partition walls, the patent prevents the high-speed fluid stream from creating large-scale upward lateral flows. The partitions break up the flow patterns and contain swirls within individual areas, preventing them from reaching the liquid surface and expelling droplets.
Solution Approach 2:
The partition walls utilize the kinetic energy of the high-speed fluid stream by directing it to flow around the partitions rather than allowing direct immersion. This converts the potentially harmful high-speed flow into a beneficial pattern that maintains productivity while preventing harmful upward flows and droplet entrainment.

AI summary
The invention relates to a lamellar separator for separating liquid droplets from a liquid-charged fluid, having at least two essentially vertically oriented lamellar profiles, which are spaced apart from one another, and which form a flow channel between them for conducting through the liquid-charged fluid and on the wall surfaces of which the liquid droplets are separated, and having a catch basin situated below the lamellar profiles for receiving the liquid separated from the liquid-charged fluid, the catch basin having at least one partition wall, which divides the catch basin into multiple areas.
