Double Nozzle Center Injection Max Suction Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Venturi tubes fail to create maximum suction pressure at the center of the current fluid, limiting the efficiency of fluid mixing and injection, as the injection position is typically at the outer point of the smaller cross-sectional area, rather than the center, which affects the mixing and transfer of fluids.
Innovation Solution
A double nozzle design with three-way intersections, a suction tube, and a suction chamber that allows for the injectable fluid to be injected at the center of the current fluid flow, creating a maximum suction pressure for efficient mixing and transfer of fluids, with adjustable sections to optimize suction pressure and mixing area design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If a venturi tube is used for fluid mixing, then fluid mixing is achieved, but the suction pressure is not maximum at the center of the current fluid
Solution Approach 1:
The patent inverts the conventional venturi tube design by placing the injection point at the center of the smaller cross-sectional area where maximum suction pressure occurs, rather than at the outer point. This inversion allows the injectable fluid to be introduced at the location of maximum suction pressure, achieving both maximum pressure utilization and effective mixing.
Solution Approach 2:
The patent modifies the local quality of the venturi tube by creating a specific injection structure at the center of the smaller cross-sectional area. This localized modification ensures that the injectable fluid is introduced precisely where the suction pressure is maximum, optimizing the mixing process at that specific location without altering the overall venturi tube functionality.
2Stress or pressure
If the injection position is at the outer point of the smaller cross-sectional area, then the structure is simple, but the suction pressure is not maximized
Solution Approach 1:
The patent inverts the conventional approach by moving the injection point from the outer point to the center of the smaller cross-sectional area. This inversion requires a modified nozzle structure with a central injection channel, but it enables the system to utilize the maximum suction pressure that naturally occurs at the center, achieving better mixing efficiency.
Solution Approach 2:
The patent segments the nozzle structure into distinct sections: a first section for the current fluid and a second section for the injectable fluid. This segmentation allows the injectable fluid to be introduced through a separate central channel at the location of maximum suction pressure, while the overall structure remains integrated and functional.
3Productivity
If maximum suction pressure is achieved at the center, then mixing efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent divides the nozzle into a first section for current fluid and a second section for injectable fluid, with the second section positioned centrally in the first section. This segmentation enables precise injection at the center where maximum suction pressure occurs, improving mixing efficiency while keeping the structure integrated and manageable.
Solution Approach 2:
The patent implements a nested structure where the second section (injection nozzle) is positioned within the first section (main flow channel). This nesting allows the injectable fluid to be introduced at the center of the current fluid flow, utilizing the maximum suction pressure for efficient mixing, while the overall structure remains compact and integrated.

Function Achieved in This Case
The double nozzle achieves continuous suction pressure for efficient mixing of injectable and current fluids, allowing for better temperature balance and reduced fluid consumption, with applications in various industries including water and sewage systems, sandblasting, and aeration systems.
Implementation Method 1
the mechanism of popular systems for measuring flow rate as well as mixing fluids is based on a theory and function of venturi meters and venturi tubes... the creation of a relative suction pressure between a pressure of a smaller cross-sectional portion of the venturi tube and a pressure of a larger cross-sectional portion
