Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Venturi systems face limitations in diffusing gas into high-flow liquids, particularly in water-treatment and aquacultural applications, due to high liquid/gas mixture velocities that can damage plant and marine life.
Innovation Solution
The development of a High Flow Venturi Nozzle (HFVN) and a Multiple-Venturi Nozzle (MVN) system, which utilizes multiple Venturi nozzles and a helical structure to reduce exit flow rates and increase gas dissolution efficiency, while also allowing for the simultaneous diffusion of multiple gases into a liquid stream.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional Venturi nozzles are used to diffuse gas into liquid, then gas dissolution occurs, but the liquid/gas mixture velocity is too high causing damage to plant and marine life
Solution Approach 1:
The invention divides a single Venturi nozzle into multiple smaller Venturi nozzles arranged in an array. Each nozzle processes a portion of the liquid flow, reducing the velocity of individual jets while maintaining overall gas dissolution efficiency. The segmented structure allows gas to be introduced at multiple locations simultaneously, achieving high productivity without excessive local velocities that would harm aquatic life.
2Object-affected harmful factors
If multiple Venturi nozzles are used to reduce exit flow velocity, then safety for aquatic life improves, but device complexity increases
Solution Approach 1:
Multiple Venturi nozzles are combined into a single integrated array structure with common gas and liquid distribution manifolds. The nozzles are arranged in a compact configuration where gas and liquid flows are distributed evenly across all nozzles simultaneously. This merging approach maintains the velocity-reduction benefit of multiple nozzles while simplifying the overall system through unified manifolds and compact arrangement, offsetting the inherent complexity of having multiple nozzles.
3Adaptability or versatility
If multiple gases are diffused simultaneously into liquid, then versatility of the system improves, but device complexity increases
Solution Approach 1:
The manifold system is designed with universal connection points and distribution channels that can accommodate multiple gas sources simultaneously. Each manifold can receive different gases through separate inlet connections and distribute them through dedicated channels to appropriate nozzle groups. This multi-functional design allows the same physical structure to handle various gas combinations (oxygen, air, nitrogen, etc.) without requiring separate diffusion systems for each gas, thereby improving versatility while controlling complexity through standardized manifold architecture.

Function Achieved in This Case
The HFVN and MVN systems achieve a higher rate of gas dissolution into liquids with lower exit flow rates, reducing the risk of damage to aquatic life and plants, and enabling efficient gas diffusion in high-flow applications with reduced energy requirements.
Implementation Method 1
First discovered by the Italian physicist Giovanni Battista Venturi in 1797, the 'Venturi effect' is the name for a natural phenomenon that sees a reduction in fluid pressure when a fluid flows through a constricted section (or choke) of a pipe
