Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas dissolution systems fail to produce consistent, microscopic-sized gas bubbles that remain entrained in water bodies due to buoyancy issues and inefficient mixing, leading to ineffective oxygen entrapment and increased energy consumption.
Innovation Solution
A submersible system comprising an upper unit with vortex winding and unwinding tubing and pressure gradient changes, and a lower unit with a filtering system, air intake, and submersible pump, to induce collisions and maintain microscopic bubbles in the fluid stream.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If compressed or pressurized gases are pumped through a fine bubble diffuser to increase gas dissolution, then gas dissolution efficiency is improved, but the gas bubbles become too big and buoyant to remain entrained in water, causing them to rise quickly and dissipate
Solution Approach 1:
The system segments the gas dissolution process into multiple stages: initial gas injection creates larger bubbles that then pass through a series of restriction openings and collision chambers that progressively break them into microscopic bubbles. This multi-stage segmentation allows the system to achieve both high gas dissolution efficiency and stable microscopic bubble sizes.
Solution Approach 2:
The invention introduces a vertical dimension to the gas-liquid mixing process by using a columnar arrangement of collision chambers and restriction openings extending vertically through the fluid stream. This vertical dimensionality allows gravitational forces to assist in breaking bubbles while maintaining pressure differential for dissolution, resolving the contradiction between dissolution efficiency and bubble size control.
2Productivity
If external liquid pumps are used to force liquid flow across gas diffusers to achieve gas dissolution, then gas dissolution can occur, but energy consumption increases and the system becomes less submersible
Solution Approach 1:
The system uses the kinetic energy of the flowing liquid itself to drive the gas dissolution process. The liquid flow creates pressure differentials and turbulence that automatically draw gas into the liquid stream through the restriction openings and collision chambers, eliminating the need for separate external pumps and reducing energy consumption while maintaining gas dissolution capability.
Solution Approach 2:
The invention employs hydraulic principles by using the liquid flow's own pressure and kinetic energy to create the conditions for gas dissolution. The restriction openings and collision chambers are designed to utilize pressure differentials and fluid dynamics to achieve gas-liquid mixing, replacing mechanical pumping with hydraulic self-service.
3Productivity
If gas is introduced into liquid carrier under pressure to dissolve gas according to Henry's Law, then gas dissolution is achieved, but the system requires complex external pumping and pressure maintenance equipment
Solution Approach 1:
The system performs preliminary gas-liquid mixing and bubble size reduction in a compact submersible unit before discharge. By pre-processing the gas dissolution and bubble stabilization in advance, the system achieves high gas dissolution rates without requiring complex external pressure maintenance equipment, as the preliminary action occurs in a self-contained unit.
Solution Approach 2:
The invention nests multiple functional elements within a compact submersible unit: gas injection openings, restriction openings, collision chambers, and discharge nozzle are all integrated into a single nested structure. This nesting allows the system to achieve complex gas dissolution functionality in a compact form factor, reducing overall system complexity while maintaining high productivity.
