Multi-Port Venturi Atomization for High-Viscosity Liquid Formula
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Venturi tubes with a single injection port suffer from flow instability, leading to increased particle size and reduced acceleration and mixing ability, especially when injecting high viscosity liquids, resulting in uneven particle distribution due to the Karman vortex phenomenon.
Innovation Solution
A Venturi device with multiple injection ports aligned perpendicular to the longitudinal axis, connected to a reservoir containing the liquid, and a pressurized gas system to stabilize the injection process, ensuring fluid communication and optimized inner diameters for converging, accelerating, and diverging sections.

1Device complexity
If a single-injection port Venturi device is used, then the device structure is simple, but the liquid formula distribution is uneven and atomization quality is poor
Solution Approach 1:
The single injection port is divided into multiple injection ports (at least two) arranged around the Venturi chamber. This segmentation allows liquid formula to be injected from multiple locations, creating multiple liquid streams that mix more uniformly with the gas flow, thereby improving distribution uniformity and atomization quality while maintaining relatively simple device structure.
Solution Approach 2:
Different injection ports are positioned at different locations around the Venturi chamber to create localized injection zones. Each injection port contributes to specific regions of the chamber, ensuring comprehensive and uniform coverage of liquid formula distribution throughout the atomization chamber, addressing the local quality variation problem.

3Device complexity
If liquid formula is not preheated, then the process is simple, but respiratory tract irritation occurs and atomization efficiency is reduced
Solution Approach 1:
The liquid formula is preheated in a heating chamber before being injected into the Venturi atomization chamber. This preliminary heating action ensures that the liquid formula reaches an optimal temperature for atomization, reducing respiratory tract irritation caused by cold liquid inhalation and improving atomization efficiency by reducing liquid viscosity and enhancing vaporization.
