Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for dissolving gas into large liquid flows, such as oxygen into water, are energy-intensive and require high energy consumption, making them expensive for large-scale applications like 2000 m3/hour water flows, and often necessitate bypass systems with moving parts or high pressure differences.
Innovation Solution
A Venturi-tube apparatus with a blade unit inside, reducing the liquid flow cross-section to create low-pressure zones, allowing gas to be dissolved into the liquid through a gas inlet and outlet system connected by channels within the blade unit, utilizing the Venturi principle to accelerate liquid flow and introduce gas efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If pressure dissolvers are used in bypass with high pressure to dissolve gas into liquid, then gas saturation in liquid is improved, but energy consumption increases significantly
Solution Approach 1:
The patent replaces the mechanical compression system (pressure dissolvers requiring high pressure pumps) with a hydraulic system utilizing the Venturi effect. The liquid flow itself creates the pressure differential needed for gas dissolution through its own kinetic energy, eliminating the need for separate high-pressure mechanical systems.
Solution Approach 2:
The system uses the kinetic energy of the liquid flow itself to create the conditions for gas dissolution. The liquid's own motion through the Venturi tube generates the low-pressure zone that draws gas in and facilitates dissolution, making the system self-sufficient without external energy input for compression.
2Productivity
If pressure dissolvers are used in bypass system, then gas dissolution capacity is improved, but system complexity and moving parts increase
Solution Approach 1:
The patent extracts the gas dissolution function from the complex bypass system with multiple components and moving parts, concentrating it into a single in-line Venturi tube element. This simplifies the overall system while maintaining dissolution capacity.
Solution Approach 2:
The in-line Venturi tube performs multiple functions simultaneously: it maintains liquid flow, creates pressure differential, draws gas in, and facilitates dissolution—all within a single component that integrates directly into the existing liquid conduit.
3Device complexity
If in-line system is used for large liquid flows, then system simplicity is improved, but gas dissolution efficiency decreases without high pressure
Solution Approach 1:
The patent applies hydraulic principles through the Venturi effect, where the liquid flow itself creates the necessary pressure conditions for gas dissolution. The hydraulic design allows efficient gas dissolution in an in-line configuration without requiring external high-pressure systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enables efficient gas dissolution into liquids with low energy demand, reducing operational costs and eliminating the need for external pumping or bypass systems, while maintaining high saturation levels, scalable for various flow rates and pipe sizes.
Implementation Method 1
A flow cross section for the liquid, i.e., a cross section within the housing through with the liquid flows or can flow, at the small cross section area is smaller than at the inlet opening. Since the flow cross section for the liquid is smaller at the small cross section area than at the inlet opening, liquid flowing through the tube has to pass an area with reduced cross section, what results in reduced static pressure in the liquid. This principle is also known as the so-called 'Venturi'-principle
