Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydrogen gas mixing devices generate high-concentration oxygen gas during water electrolysis, which is undesirable for direct release to the atmosphere, and there is a need to treat and dilute this oxygen gas effectively.
Innovation Solution
A hydrogen gas mixing device that includes a water electrolysis part generating hydrogen and oxygen gases, a mixing gas supply part providing a non-combustible gas like nitrogen, and a gas mixing part that mixes hydrogen and nitrogen gases, with a dilution gas supply part introducing nitrogen into the oxygen flow path to dilute the oxygen gas before release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high-concentration oxygen gas is generated in the water electrolysis part, then hydrogen gas generation efficiency is improved, but direct release of high-concentration oxygen gas to the outside creates safety hazards
Solution Approach 1:
The patent introduces a non-combustible dilution gas (such as nitrogen or carbon dioxide) as an intermediary substance that mixes with the high-concentration oxygen gas in the oxygen flow path. This dilution gas acts as a mediator to reduce the oxygen concentration to a safe level before atmospheric release, thereby maintaining the benefits of high-concentration oxygen generation while eliminating the safety hazard of direct high-concentration oxygen release to the environment
2Object-affected harmful factors
If a dilution gas supply part is added to introduce non-combustible gas into the oxygen flow path, then oxygen gas safety is improved, but device complexity increases
Solution Approach 1:
The patent designs the dilution gas supply part to serve multiple functions: it not only dilutes the oxygen gas for safety purposes but also provides a controllable gas flow system that can be integrated with the existing hydrogen and mixing gas supply systems. The dilution gas supply part can share control mechanisms and flow regulation components with other gas supply systems, thereby achieving oxygen safety improvement while minimizing the increase in overall device complexity
