Agricultural Liquid Atomizer Tangential Canal Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid atomizers for agricultural use do not efficiently produce a uniform fine mist due to suboptimal vortex generation and outlet design, leading to impaired tangential velocity and spray angle.
Innovation Solution
The design includes a canal system with a straight section that opens tangentially into a cylindrical and coned swirl chamber, optimizing liquid flow and velocity for uniform spray formation, with specific geometric relationships between canal dimensions and chamber angles to enhance spray quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a curved canal is used to direct liquid into the swirl chamber, then the liquid can enter the chamber, but the tangential velocity and spray angle are impaired
Solution Approach 1:
The patent applies curvature by designing the canal to open tangentially into the cylindrical portion of the swirl chamber, creating a curved flow path that generates optimal tangential velocity. The cylindrical and coned portions of the chamber work together to swirl the liquid jet, transforming the flow into a fine spray with improved atomization compared to straight canal designs.
2Ease of manufacture
If the coned portion has a small angle, then the chamber is easier to manufacture, but the spray angle and tangential velocity decrease
Solution Approach 1:
The patent optimizes the cone head angle parameter within the range of 60-135 degrees to achieve the best balance between manufacturing ease and spray performance. This parameter optimization ensures sufficient tangential velocity is generated while maintaining a practical manufacturing angle that is not excessively sharp or flat.
3Manufacturing precision
If the outlet is narrow to produce fine mist, then the spray quality improves, but the liquid flow rate decreases
Solution Approach 1:
The patent uses hydraulic principles by designing the canal dimensions and chamber geometry to optimize liquid flow through the narrow outlet. The tangential opening of the canal and the cylindrical-coned chamber configuration create a vortex that efficiently atomizes the liquid, allowing fine mist production while maintaining adequate flow rate through proper hydraulic design.
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 atomizer emits a fine liquid spray with Sauter Mean Diameter (SMD) smaller than 60 μm, achieving optimal tangential velocity and minimizing hydraulic losses, resulting in a uniform and efficient mist emission.
Implementation Method 1
water flowing through the atomizer is forced to spin in the R-like path and exit as a fine spray of atomized liquid via a narrow outlet after it is swirled
Implementation Method 2
at least a section of the canal extends along a straight line and tangentially opens into the chamber to thereby form tangential direction and velocity to liquid jets entering the chamber
