Problem
Electrolysis devices generating sodium hypochlorite pose a risk due to the production of hydrogen gas as a by-product, which is explosive and requires additional processes for safe disposal, increasing installation costs, space, and maintenance complexity.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hydrogen gas is discharged to the atmosphere after dilution with ambient air, then the risk of hydrogen gas explosion is reduced, but additional equipment (air blower, gas-liquid separator) and processes are required, increasing device complexity and installation costs
Solution Approach 1:
The patent converts the harmful hydrogen gas by-product into a beneficial resource by using it as fuel for oxidation reactions. The hydrogen gas generated during electrolysis is directed to a combustion chamber where it burns to produce heat, which is then utilized for water heating or steam generation. This eliminates the need for complex discharge systems while providing useful thermal energy.
Solution Approach 2:
The electrolysis system serves itself by using its own hydrogen by-product as fuel for the combustion chamber. The hydrogen generated during electrolysis is automatically directed to burn and produce heat, which can be used for preheating feed water or generating steam for the electrolysis process itself, creating a self-sustaining energy loop.
2Reliability
If hydrogen gas is purified and recycled by increasing purity to upper limit of explosive range, then hydrogen gas is removed from the system, but additional purification equipment and processes are required, increasing device complexity and installation space
Solution Approach 1:
Instead of purifying and recycling hydrogen gas, the patent directly utilizes the hydrogen as fuel for combustion. The hydrogen gas is burned in a combustion chamber to produce heat energy, converting the potentially harmful by-product into a useful energy source for water heating and steam generation, eliminating the need for purification equipment.
Solution Approach 2:
The patent replaces complex mechanical purification and recycling systems with a simpler combustion-based approach. Instead of using mechanical separators, filters, or recycling pumps to manage hydrogen gas, the system uses combustion to directly consume and convert the hydrogen into useful thermal energy.
3Reliability
If additional processes are added to remove hydrogen gas safely, then safety from hydrogen gas explosion is improved, but installation costs and maintenance complexity increase
Solution Approach 1:
The patent eliminates safety concerns by completely consuming the hydrogen gas through combustion rather than attempting to manage or dispose of it. The hydrogen is burned to produce heat for water heating and steam generation, converting a safety hazard into a useful energy source and simplifying the overall system.
Solution Approach 2:
The electrolysis system generates its own fuel (hydrogen gas) and uses it to meet part of its own energy needs through the combustion chamber. The heat from hydrogen combustion is used for preheating feed water or generating steam, reducing external energy requirements and simplifying the system architecture.
