Electrolytic Ion Water Recirculation for Selective pH Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrolytic ion water generation apparatuses are limited to producing a single pH value of electrolytic ion water, lacking the capability to selectively generate waters with different pH values.
Innovation Solution
The apparatus includes a system with multiple solution storage tanks and flow systems to manage electrolytic ion water of varying pH values, utilizing a DC power source to apply voltage across electrode plates and switch between raw water and generated solution supply systems to produce electrolytic ion waters of specific pH values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional electrolytic ion water generation apparatus is used, then electrolytic ion water can be generated, but only a single pH value can be produced
Solution Approach 1:
The electrolytic bath is designed to perform multiple functions: it can generate electrolytic ion water with different pH values by switching between raw water supply and generated solution supply modes. The same bath structure serves both as the electrolysis chamber and as a system that can produce multiple product types (pH 12.5 and pH 13.1 electrolytic ion water), eliminating the need for separate apparatus for each pH value.
Solution Approach 2:
The apparatus incorporates dynamic switching capability between different water supply sources (raw water or generated solution) to the cathode chamber. This dynamic control allows the system to change its operation mode and produce different pH values on demand, making the apparatus adaptable rather than fixed in its output.
2Adaptability or versatility
If multiple storage tanks and flow systems are added to enable selective pH generation, then versatility improves, but device complexity increases
Solution Approach 1:
The generated solution tank serves dual purposes: it stores electrolytic ion water produced during operation and also functions as a source of raw material (generated solution) for subsequent electrolysis cycles. By merging the storage function with the material recycling function, the system reduces the need for separate tanks for each purpose.
Solution Approach 2:
The system recycles generated electrolytic ion water back into the cathode chamber as a supply source for continued electrolysis. Instead of discarding the generated solution, it is recovered and reused, enabling continuous operation and multiple pH value generation without requiring external water sources for each cycle.
