Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atomizer nozzles face challenges in maintaining long service life due to contamination risks and limited adaptability for various media, especially aggressive chemicals, and struggle with efficient aerosol generation across a wide range of flow rates.
Innovation Solution
The atomizer nozzle design features a tubular nozzle lance with a vortex generator and a nozzle insert, where a small tube is guided through the entire nozzle, minimizing contact between the medium and nozzle components, allowing for external mixing and easy replacement, and using a variety of tube materials to prevent contamination and adapt to different flow rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the medium is guided directly through the nozzle components, then the atomization process is simpler, but the internal nozzle geometry is contaminated and service life is reduced
Solution Approach 1:
The system is divided into separate components: the tube through which the medium flows, the nozzle components that generate the gas stream, and the mixing zone where atomization occurs. This segmentation prevents the medium from contacting the nozzle geometry while maintaining atomization functionality.
Solution Approach 2:
A gas stream acts as an intermediary that carries the medium through the atomization process without direct contact between the medium and nozzle components. The gas stream transports the medium through the central bore while the nozzle components remain separate and uncontaminated.
2Device complexity
If fixed nozzle components are used, then the structure is simpler, but adaptability to different media and flow rates is limited
Solution Approach 1:
The system allows dynamic adjustment by replacing the tube component with different materials and dimensions suited to different media and flow rates. The first fixing device enables easy replacement, providing adaptability without requiring complex adjustable mechanisms.
Solution Approach 2:
The nozzle components (vortex generator, nozzle insert, fixing devices) serve multiple functions and can work with various tube materials and configurations. This universal design allows the same basic structure to handle different media types and flow rates by simply changing the tube.
3Ease of manufacture
If the tube is fixed permanently in the nozzle, then assembly is simpler, but replacement for blockage or adaptation is difficult
Solution Approach 1:
The tube is designed as a separate, replaceable component rather than being permanently integrated into the nozzle. The first fixing device provides a simple mechanical connection that allows easy removal and replacement of the tube without affecting other nozzle components.
Solution Approach 2:
The tube can be discarded when blocked or worn and replaced with a new or different tube. The fixing device allows quick replacement while retaining the valuable nozzle components (vortex generator, nozzle insert, base body) for continued use.
