Corrosion Resistant Ozone Generator Dielectric Chamber
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ozone generators used for purifying and disinfecting water in applications like spas, pools, and laundry are prone to corrosion due to the use of air as an oxygen source, leading to the formation of corrosive nitrogenous compounds that reduce their efficiency and lifespan.
Innovation Solution
A Corrosion Resistant Ozone Generator is developed, featuring a discharge chamber made entirely or substantially from dielectric materials, with electrodes outside the chamber, using a coronal discharge method to generate ozone efficiently and minimize maintenance, and is designed to be compact and cost-effective.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If air is used as an oxygen source in conventional ozone generators, then the device can operate continuously to produce ozone for water purification, but corrosive nitrogenous compounds form that reduce efficiency and lifespan
Solution Approach 1:
The harmful nitrogenous compounds formed from air are extracted or removed from the discharge chamber environment. The patent uses a dielectric material that prevents these compounds from forming or adhering to surfaces, effectively taking out the corrosive elements from the system while maintaining continuous ozone production capability.
Solution Approach 2:
A dielectric material is introduced as an intermediary between the electrical discharge and the water/air environment. This dielectric barrier prevents direct contact between corrosive nitrogenous compounds and metal components, mediating the interaction and protecting the system while allowing ozone generation to proceed.
2Productivity
If air is used as an oxygen source, then ozone can be generated for disinfection, but corrosion occurs that requires frequent maintenance
Solution Approach 1:
The dielectric material provides self-protecting properties to the ozone generator system. Instead of requiring external maintenance to remove corrosion, the dielectric barrier automatically prevents corrosive compounds from damaging components, making the system self-maintaining and reducing service intervals.
3Reliability
If a dielectric discharge chamber is used to prevent corrosion, then device lifespan is extended, but device complexity increases
Solution Approach 1:
The discharge chamber is constructed using composite materials - specifically a dielectric material combined with metal support structures. This composite approach provides both the corrosion resistance of the dielectric and the structural integrity of metal, achieving extended lifespan without excessive complexity.
4Reliability
If electrodes are placed outside the discharge chamber, then corrosion is minimized, but ozone generation efficiency may be affected
Solution Approach 1:
The dielectric material serves as an intermediary that transmits electrical energy from external electrodes to the gas mixture in the discharge chamber. This allows electrodes to be positioned outside the corrosive environment while still enabling efficient ozone generation through the dielectric barrier discharge mechanism.
