Ozone Electrolysis Cell Heat Dissipation via Water Flow and Elastic Oscillation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ozone generators have unsatisfactory heat dissipation performance, leading to reduced ozone water concentration and potential damage to the proton exchange membrane due to poor scaling management.
Innovation Solution
The ozone electrolysis cell design includes a shell with a water inlet and outlet, an electrolysis cavity with electrode holders, and an electrolysis assembly comprising an anode, proton exchange membrane, and cathode. The assembly features a water gap and strategically sized water holes to facilitate water flow and gap formation between components, enhancing heat dissipation and preventing membrane damage. Additionally, an elastic member maintains the cathode in a micro-oscillation state to prevent scale accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If electrodes are disposed close to a PEM to simplify internal structure, then device complexity is reduced, but heat dissipation performance deteriorates and ozone water concentration cannot be increased
Solution Approach 1:
The electrolysis cavity is divided into multiple independent electrolysis sub-cavities, each with its own electrode assembly. This segmentation allows for optimized water flow paths and heat dissipation in each sub-cavity while maintaining overall structural simplicity, resolving the contradiction between structural simplicity and heat dissipation performance.
Solution Approach 2:
Water holes are introduced at different positions and orientations within the electrode assemblies, creating multi-dimensional water flow paths. This dimensional approach enhances heat dissipation and ozone water concentration without complicating the overall structure, as the water flow utilizes spatial dimensions efficiently.
2Device complexity
If electrodes are disposed close to a PEM to simplify internal structure, then device complexity is reduced, but productivity deteriorates due to reduced ozone water concentration
Solution Approach 1:
Multiple electrolysis sub-cavities are arranged in parallel within the electrolysis cavity, each generating ozone water independently. This segmentation increases the total ozone water production capacity and concentration without requiring a complex single-cavity design, thereby improving productivity while maintaining structural simplicity.
Solution Approach 2:
Multiple electrolysis sub-cavities are combined within a single electrolysis cavity structure, allowing the system to achieve high ozone water concentration and productivity through the collective output of multiple units while sharing common structural components, thus improving productivity without proportionally increasing device complexity.
3Reliability
If water velocity is increased to flush scale from electrode surfaces, then reliability is improved, but energy consumption increases
Solution Approach 1:
Water holes are pre-positioned at specific locations on electrodes and PEMs to create targeted high-velocity water jets that effectively remove scale. This preliminary positioning of water holes ensures that scale removal occurs at critical points without requiring uniformly high water velocity throughout the entire system, thereby improving reliability while minimizing energy consumption.
Solution Approach 2:
Water holes are strategically positioned to create localized high-velocity water flow only at areas where scale accumulation is most problematic (electrode surfaces and MEM surfaces). This local quality approach concentrates energy where needed for scale removal rather than increasing overall water velocity system-wide, improving reliability without excessive energy consumption.
