Curved Deflecting Elements in Wind Separator Guide Vanes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wind separators that introduce feedstock and separating air jointly suffer from uncontrolled entry of the mixture into the separation zone, leading to reduced sorting efficiency.
Innovation Solution
A separator design featuring a guide vane assembly with downward-pointing curved and/or bent deflecting elements between vertical guide vanes, which imparts horizontal and vertical movement components to the gas-solids mixture, ensuring a controlled entry into the separation zone and enhancing separating efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the mixture of feedstock and separating air flows vertically against the deflecting elements, then the结构简单 (structure is simple), but the flow becomes uncontrolled causing backflow or swirling before entering the guide vane assembly
Solution Approach 1:
The deflecting elements are designed with curved surfaces instead of flat surfaces. The curved deflecting elements guide the gas-solids mixture smoothly into the separating zone, preventing backflow and swirling while maintaining structural simplicity. The curvature allows the flow to follow a controlled path without abrupt changes in direction.
Solution Approach 2:
The guide vane assembly is divided into multiple vertical guide vanes with deflecting elements positioned between them. This segmentation creates multiple flow channels that distribute and control the mixture flow, preventing uncontrolled backflow and swirling while maintaining overall structural simplicity.
2Reliability
If deflecting elements are added to control flow entry, then the flow control stability improves, but the device complexity increases
Solution Approach 1:
The deflecting elements are integrated into the existing guide vane assembly structure, merging the flow control function with the guiding function. This combination achieves improved flow control stability without proportionally increasing device complexity, as the deflecting elements work in conjunction with the vertical guide vanes rather than as separate components.
Solution Approach 2:
The deflecting elements serve multiple functions: they guide the flow, prevent backflow, eliminate swirling, and direct the mixture into the separating zone. This multi-functionality achieves improved flow control stability without requiring additional separate components, thereby limiting the increase in device complexity.
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 controlled flow results in improved separation efficiency by ensuring a uniform and directed flow to the separator wheel, effectively separating fine and coarse particles.
Implementation Method 1
at least one deflecting element is arranged between at least two adjacent vertical guide vanes and has at least one downward-pointing curved and/or bent portion
Implementation Method 2
fine or small particles are influenced more strongly and carried along by the gas stream than are large or coarse particles
Implementation Method 3
Coarse particles, on the other hand, strike against the fins and are bounced back in this way and finally drop down because of gravity
