Impactor Separator Element Shallow Angle Gas Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing separator systems for gas streams are inefficient due to the inability of gases to flow freely off the clean side of the separator elements, leading to impaired separation efficiency.
Innovation Solution
An impactor-separator element with a separator means in the form of a mesh or grid element, positioned at a shallow angle of attack within a holder that allows the gas to flow off freely on the clean side, and includes a flow directing element to control the gas flow and optimize the angle of incidence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the separator element is arranged in the flow channel with the side wall forming an acute angle, then the separator element can be installed in the flow channel, but the gas cannot flow off freely which impairs separation efficiency
Solution Approach 1:
The invention changes the orientation of the separator element from a conventional arrangement where the side wall forms an acute angle to a shallow angle of attack configuration. This dimensional change in the angle of installation allows gas to flow off freely on the clean side while maintaining effective separation, resolving the contradiction between installation feasibility and flow freedom.
Solution Approach 2:
The invention modifies the critical parameter of the angle of attack to be shallow (close to parallel with the flow direction) rather than forming an acute angle with the side wall. This parameter change enables both free gas outflow and high separation efficiency by optimizing the flow dynamics through the separator element.
2Productivity
If the separator means is positioned with a shallow angle of attack, then the separation efficiency is improved, but the angle of incidence control becomes more critical
Solution Approach 1:
The holder is designed with pre-set geometric features that automatically establish the optimal shallow angle of attack when the separator element is installed. This preliminary configuration of the holder structure eliminates the need for precise manual adjustment during installation, reducing the criticality of angle control while maintaining high separation efficiency.
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
The solution significantly improves the efficiency of the separator system by allowing free outflow of gas, optimizing the angle of attack, and enhancing the separation of fluid droplets from the gas stream, even for small aerosols with low pressure loss.
Implementation Method 1
the gas flow is strongly deflected over a short distance of the order of magnitude of the diameter of the passage opening when flowing through the usually very small passage openings, in order to run essentially transversely to the main plane of the separator element within the thickness of the separator element
Implementation Method 2
The gas flow is therefore very strongly accelerated transversely, so that fluid droplets or aerosols deposit on the walls or edges of the passage openings

AI summary
The invention is based on an impactor-separator element (10) for separating fluid droplets (12) from a gas stream, comprising at least one separator means (14a, 14b) having a raw side and a clean side, said separator means (14a, 14b) being designed as a mesh or grid element and being fixed in a holder (16), wherein the holder (16) is designed to position the separator means (14a, 14b) with a shallow angle of attack in the gas stream.It is proposed to provide at least one element (36, 46) arranged in the gas flow upstream of the separation means (14a) for controlling the gas flow impinging on the separation means.
