Solution Overview
Problem
Conventional ozonated water producing apparatuses face issues with varying ozone dissolution efficiency and concentration stability due to non-optimal flow rates of pure water, leading to increased ozone gas usage and unstable ozonated water generation.
Innovation Solution
A gas-dissolved liquid producing apparatus with multiple gas dissolving units having different optimum flow rates, controlled by a flow rate detector and controller to ensure appropriate unit selection based on the liquid flow rate, optimizing gas dissolution efficiency and concentration stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single gas dissolving unit with a fixed optimum flow rate is used, then the gas dissolution efficiency is optimized at that specific flow rate, but the dissolution efficiency deteriorates when the liquid flow rate deviates from the optimum, and the concentration stability of the gas-dissolved liquid deteriorates
Solution Approach 1:
The gas dissolving unit is divided into multiple segments (first gas dissolving unit and second gas dissolving unit), each with different optimum flow rates. The system segments the dissolution function across multiple units with varying characteristics, allowing adaptation to different flow rate conditions while maintaining optimal dissolution efficiency in each segment.
Solution Approach 2:
The system dynamically switches between different gas dissolving units based on the detected liquid flow rate. The controller adjusts which unit receives gas supply according to real-time flow conditions, making the system adaptive and dynamic rather than fixed, thereby maintaining optimal performance across varying operating conditions.
2Loss of substance
If the liquid flow rate is reduced to decrease ozone gas usage, then the gas dissolution efficiency improves at the optimum flow rate, but the concentration stability of the gas-dissolved liquid deteriorates when the flow rate is excessively lower than the optimum
Solution Approach 1:
The system segments the gas dissolving function into multiple units with different optimum flow rates. When liquid flow rate is reduced, the controller switches to a gas dissolving unit designed for lower flow rates, maintaining both efficient ozone gas usage and stable concentration of the dissolved liquid.
Solution Approach 2:
The system changes the operating parameters by switching between gas dissolving units with different characteristics. Each unit is optimized for specific flow rate ranges, allowing the system to adjust its parameters to match current operating conditions and maintain both efficiency and stability.
