Plate Separator Projections with Sharp Edges for Gas Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cross-flow, plate-shaped separators for liquids from gas flows, such as oil mist, do not achieve optimal separation of liquid droplets and particles due to limitations in the design of projections on the separating profiles.
Innovation Solution
The introduction of projections with flat, adjoining outer surfaces forming acute angles, creating pointed edges that protrude into the gas stream, enhances the separation properties by promoting agglomeration and preventing re-entrainment of particles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a bead-shaped projection is used on the separating profile, then the structure is simple and easy to manufacture, but the separation properties are insufficient
Solution Approach 1:
The projection is designed with different surface characteristics in different regions: a first outer surface that is essentially flat and perpendicular to the deflection surface, and a second outer surface that is essentially flat and adjoins at an acute angle. This local differentiation creates specific flow interaction zones that enhance separation properties without requiring complete structural redesign.
Solution Approach 2:
The invention transitions from a bead-shaped (curved) projection to a projection with flat surfaces and sharp edges. The pointed edge formed by the intersection of the first and second outer surfaces creates a geometric discontinuity that generates minicyclones and flow separation, improving particle agglomeration and separation efficiency.
2Productivity
If the first outer surface emerges from the deflection surface at an angle between 60° and 120° (rather than perpendicular), then the flow interaction is improved, but the manufacturing precision requirement increases
Solution Approach 1:
The angle between the first outer surface and the deflection surface is optimized to be between 60° and 120°, with perpendicular (90°) being particularly favorable. This parameter optimization balances flow interaction effectiveness with manufacturing feasibility, allowing for improved separation efficiency while remaining practical for production.

AI summary
The invention relates a plate-shaped separator for separating fluids from a gas flow, particularly for separating oil mist, wherein the flow hits the separator transversely, wherein the separator comprises a plurality of separating profiles, which are arranged in parallel next to each other transversely to the flow direction of the gas flow and which each form two curved deflection surfaces, which lie opposite each other in a laterally offset manner with the concave side thereof and on which a gas flow to be purified flows along successively, wherein the deflection surfaces enclose an eddy chamber having an inlet gap and an outlet gap between said deflection surfaces and end at the longitudinal edges of the deflection surfaces in a protuberance that projects over the deflection surfaces and extends along the longitudinal edges, wherein in order to further improve the separation of particles from the gas flow to be purified, it is proposed that at least one of the protuberances comprise a first substantially plane outer surface exiting from the deflection surface substantially transversely to the deflection surface and a second substantially plane outer surface connecting thereto at a sharp angle so that the at least one protuberance forms a sharp edge projecting into the gas flow flowing along the deflection surfaces.
