Radial Electrolysis Cell Switching for Even Electrode Wear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrolysis cells for water treatment suffer from premature wear of electrodes, leading to frequent replacement and high maintenance costs due to uneven distribution of wear across conductive plates.
Innovation Solution
The electrolysis cell employs a configuration with multiple sets of conductive plates arranged radially and controlled through a switching device to distribute wear evenly across all plates, ensuring continuous operation and reducing maintenance needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrodes are connected continuously to electric power supply source, then electrolysis treatment is maintained, but electrode wear increases leading to premature failure
Solution Approach 1:
The patent implements periodic disconnection of electrodes from the power supply source through a switching device. Each electrode is disconnected for a predetermined time period between connection cycles, creating a periodic on-off action that allows wear recovery and extends electrode service life while maintaining continuous electrolysis treatment through alternating electrode activation.
2Reliability
If polarity inversion is performed between connected states, then scale deposits are removed, but electrode wear increases due to brutal transitions
Solution Approach 1:
The patent applies preliminary disconnection action before polarity inversion. Each electrode is disconnected from the power supply for a predetermined time period before being reconnected with inverted polarity. This preliminary disconnection softens the transition, prevents brutal electrical shocks, and reduces electrode wear while still achieving scale deposit removal through the polarity reversal.
3Reliability
If multiple sets of conductive plates are used, then wear is distributed evenly, but device complexity increases
Solution Approach 1:
The patent divides the conductive plates into multiple independent sets (first set, second set, third set) that can be independently connected or disconnected from the power supply source. This segmentation allows even distribution of wear across all plates by selectively activating different sets, while the modular structure manages complexity through systematic organization of the multiple plate sets.
