Solution Overview
Problem
Existing oxygen dissolution technologies struggle to generate high-concentration oxygenated water beyond supersaturation levels without significant degassing, requiring complex equipment and high pressures, making them unsuitable for small-scale or indoor use.
Innovation Solution
A high-concentration oxygenated water generation apparatus with a dissolution tank featuring alternating dispersion and collection trays, a pressure dissolution unit, and stabilization tubes to maximize contact area and time, and inhibit degassing, allowing for continuous oxygen dissolution under normal pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional aeration systems are used to dissolve oxygen in water, then oxygen concentration can be increased to saturation level, but it is difficult to achieve supersaturation concentration
Solution Approach 1:
The dissolution tank is divided into multiple stages with alternating dispersion trays and collection trays. Each tray creates separate zones for gas-liquid contact and collection, enabling progressive oxygen dissolution through multiple stages rather than a single contact zone, thus achieving supersaturation effectively.
Solution Approach 2:
The patent introduces a vertical multi-stage structure with alternating dispersion and collection trays arranged in the vertical dimension. This transforms a single-plane gas-liquid contact into a multi-level three-dimensional dissolution process, maximizing contact area and residence time for supersaturation achievement.
2Quantity of substance
If high-pressure vessels are used to dissolve oxygen to supersaturation level, then dissolved oxygen concentration can be increased, but apparatus size increases and continuous production becomes difficult
Solution Approach 1:
The circulation pump creates self-circulating flow that continuously moves water through the dissolution tank and back, eliminating the need for external high-pressure vessels or complex pumping systems. The system uses its own circulation to maintain supersaturation and enable continuous production.
Solution Approach 2:
The patent uses hydraulic circulation through the dissolution tank instead of pneumatic high-pressure compression. Water is circulated through the tank where oxygen dissolves under atmospheric pressure, avoiding the need for high-pressure vessels while achieving supersaturation through extended contact time and multi-stage trays.
3Quantity of substance
If oxygen microbubbles are injected under pressure and dwelled for predetermined time, then supersaturation can be achieved, but rapid degassing occurs during decompression
Solution Approach 1:
The circulation pump and multi-stage trays perform preliminary oxygen dissolution action while water is circulating through the system. By the time oxygenated water reaches the storage tank, supersaturation is already established, and the continuous circulation maintains this state without requiring subsequent high-pressure dwelling or risking degassing during decompression.
4Use of energy by moving object
If circulation pump is stopped, then energy consumption is reduced, but dissolved oxygen concentration decreases due to degassing
Solution Approach 1:
The circulation pump operates continuously to maintain constant water circulation through the dissolution tank, ensuring that oxygen dissolution action is ongoing without interruption. This continuous circulation prevents degassing by constantly renewing the gas-liquid contact, maintaining supersaturation even during extended periods without pump shutdown.
