Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a Venturi tube is used to mix gas and liquid, then the mixing process is simple, but the gas dissolving rate is low and gas concentration in liquid is insufficient
Solution Approach 1:
The gas dissolving system is divided into two separate mixers: a first mixer for initial gas-liquid mixing and a second mixer for further gas dissolution. This segmentation allows each mixer to optimize for gas dissolving efficiency, achieving high gas concentration in liquid while maintaining reasonable system complexity through modular design
Solution Approach 2:
The system transitions from a single-stage mixing process to a two-stage sequential mixing process, adding a temporal and process dimensional aspect. The liquid flows through both mixers in sequence, allowing progressive gas dissolution that significantly enhances the overall gas dissolving rate and final gas concentration
2Object-affected harmful factors
If ozone is used for water disinfection, then environmental friendliness is improved, but ozone instability and short half-life reduce effectiveness
Solution Approach 1:
The system performs preliminary gas dissolution by introducing ozone gas into liquid through two mixers before the liquid reaches the application point. This preliminary action ensures high ozone concentration is achieved in advance, compensating for ozone's short half-life by maximizing dissolution efficiency before the liquid leaves the system
Solution Approach 2:
The system utilizes pressure changes to enhance ozone dissolution. By controlling pressure conditions in the mixers and using pressure valves to regulate flow, the system optimizes physical dissolution parameters to achieve high ozone concentration in liquid despite ozone's inherent instability and rapid decomposition
3Productivity
If high ozone concentration liquid is produced, then disinfection effectiveness is improved, but safe handling and environmental release become problematic
Solution Approach 1:
The system converts potentially harmful undissolved ozone into beneficial dissolved ozone. By using two mixers with pressure control, the system maximizes ozone dissolution efficiency, transforming what would be harmful undissolved gas into useful dissolved ozone for disinfection, while minimizing environmental pollution
Solution Approach 2:
The liquid acts as an intermediary medium that captures and contains ozone. The two-mixer system efficiently transfers ozone from gaseous to dissolved state in the liquid, which then serves as a safe carrier for transporting and applying ozone for disinfection purposes, preventing direct release of harmful ozone gas to the environment

Implementation Method 4
the other mixer is used to mix raw liquid with the gas-contained liquid
Implementation Method 5
By adding a gas destructor to the degassing device, the system according to the present invention can process gases which are harmful and cannot be released to the outside environment
Implementation Method 6
The undissolved gas in the liquid will react with the destruction medium to become harmless gases which can safely be released to the outside environment
Implementation Method 7
The ozone molecule is very unstable and has a short half-life. Therefore, it will decay after some time into its original form of oxygen (O2) according to the reaction presented below: 2O3→3O2
Implementation Method 8
By controlling the pressure valves, the system may provide two dosed liquid outputs

AI summary
A gas dissolving system using double mixers to generate a higher gas concentration in liquid is disclosed. The gas dissolving system includes two gas mixers, a degassing device, pressure valves, a pressure sensor, and a pump. Liquid flows through mixers to entrain gas therein, and it thus contains dissolved gas and undissolved gas. The liquid subsequently flows into the degassing device so that undissolved gas is released to the outside environment, and dissolved gas remains in the liquid. The liquid with dissolved gas combines with raw liquid and is diluted so that it becomes liquid with a desired gas concentration as the output. A high gas concentration of liquid is obtained after more cycles of fluid flow through the mixers to dissolve gas without combining raw liquid.
