Three-Compartment Electrolysis Device for Neutral Oxidative Water
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing two-compartment electrolysis devices produce anode water with high oxidative potential but strongly acidic pH, which causes corrosion and is not suitable for wound healing or sterilization, as it is too acidic and corrosive.
Innovation Solution
A three-compartment electrolysis device is introduced, with a middle compartment between the anode and cathode compartments, using a separating membrane and porous electrodes, allowing for the production of anode water with a pH range from weakly acidic to weakly alkaline, enhancing the production of active oxygen species and residual chlorine, and mixing with cathode water to achieve a neutral pH.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrolysis current is increased to increase ORP for effective sterilization, then microorganism killing power is improved, but pH becomes strongly acidic causing corrosion
Solution Approach 1:
The electrolysis cell is divided into three compartments: anode compartment, cathode compartment, and middle compartment. This segmentation allows separate control of oxidation reactions (producing high ORP water) and alkaline environment (preventing corrosion), enabling both sterilization effectiveness and material protection
Solution Approach 2:
The middle compartment acts as an intermediary between the anode and cathode compartments. It contains ion exchange resins that facilitate ion transfer while maintaining pH balance, allowing high ORP anode water to be produced without direct contact with highly alkaline cathode water that would cause corrosion
2Reliability
If two-compartment cell is used to produce high ORP anode water, then sterilization capability is improved, but pH control becomes difficult leading to strong acidity
Solution Approach 1:
The cell is segmented into three compartments with the middle compartment specifically designed to control pH. Ion exchange resins in the middle compartment regulate ion transfer, maintaining anode water pH between 4-7 while still achieving ORP >1100mV for effective sterilization
Solution Approach 2:
The invention changes the pH parameter control mechanism by introducing the middle compartment with ion exchange resins. This allows the anode water pH to be maintained in the range of 4-7 (optimally 6-7), preventing strong acidity while maintaining high sterilization capability through ORP >1100mV
3Reliability
If electrolysis current is increased to enhance microorganism killing power, then ORP increases, but chloride ion transfer increases causing strong acidity
Solution Approach 1:
The middle compartment with ion exchange resins acts as a mediator that controls chloride ion transfer from cathode to anode compartment. This prevents excessive chloride accumulation in the anode compartment, allowing high current operation for microorganism killing without strong acidification from chloride hydrolysis

AI summary
This invention provides the oxidative mixed water with pH around 7.4 ranging from the weak acidity to weak alkalinity, high power of killing microorganisms, and high power of healing wound by electrolysis using the three-compartment cell composed of an anode compartment, a cathode compartment, and a middle compartment between the anode compartment and the cathode compartment.
