Sprayer Nozzle Diffuser System Drift Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sprayer nozzles face challenges in reducing drift, stabilizing spray angle, and achieving precise fluid dispersion, leading to unintended fluid travel and inefficient application patterns.
Innovation Solution
The design incorporates a diffuser positioned close to the nozzle outlet, oriented either perpendicularly or parallel to the spray opening, which disrupts fluid flow and energy concentration, reducing drift and stabilizing the spray pattern by dispersing fluid flow and concentrating energy within the nozzle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional sprayer nozzle is used, then the fluid can be dispersed over an area, but drift occurs and fluid inadvertently travels to unintended areas
Solution Approach 1:
The nozzle is divided into multiple functional components: a body defining a fluid pathway, a diffuser with diffusion openings positioned within the body, and a nozzle outlet with spray openings. This segmentation allows the diffuser to disrupt and redistribute fluid flow before it reaches the spray openings, reducing drift while maintaining precise spray pattern control through the coordinated action of diffusion and spray elements
Solution Approach 2:
The diffuser acts as an intermediary element between the fluid pathway and the nozzle outlet. It receives fluid from the body, disrupts the flow through its diffusion openings, and redistributes the fluid energy before it reaches the spray openings. This intermediary component reduces the harmful drift effect while preserving the desired spray precision
2Object-affected harmful factors
If the nozzle outlet is positioned close to the spray opening, then drift is reduced, but the spray angle stability may be affected
Solution Approach 1:
The diffuser introduces dynamic flow disruption through its diffusion openings, creating a redistributed fluid pattern that is more resistant to drift. The interaction between the diffuser-induced flow turbulence and the nozzle outlet geometry dynamically stabilizes the spray angle, allowing the system to adapt to varying flow conditions while maintaining both drift reduction and spray stability
