Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gas-liquid separation methods in semiconductor and electronic component manufacturing fail to achieve optimal gas solubility due to insufficient contact time between gas and liquid, leading to inefficient cleaning processes.
Innovation Solution
A gas-dissolved liquid manufacturing device is designed with a pump, nozzle, and gas-liquid separation tank configuration that generates micro bubbles and promotes complex flow patterns, increasing gas-liquid contact time and solubility by adjusting flow rates and using flow path adjustments and protrusions within the tank.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gas-liquid mixture is introduced from vertically downward to upward in a gas-liquid separation tank, then smooth gas-liquid separation is achieved, but gas dissolution efficiency cannot reach the target
Solution Approach 1:
The patent inverts the conventional flow direction by introducing the gas-liquid mixture from the upper part of the tank downward, rather than from below upward. This reverse flow configuration allows the liquid to flow downward while gas bubbles rise, creating counter-current flow that extends contact time between gas and liquid phases, thereby improving gas dissolution efficiency while maintaining separation quality
Solution Approach 2:
The patent introduces protrusions on the inner wall of the gas-liquid separation tank to create complex flow patterns. These protrusions generate turbulence and eddy currents that dynamically enhance gas-liquid mixing and contact, preventing stagnant zones and ensuring thorough gas dissolution while the gas-liquid mixture continues to flow downward
2Quantity of substance
If long contact time between gas and liquid is ensured, then gas solubility is improved, but separation efficiency decreases
Solution Approach 1:
The patent segments the gas-liquid separation tank into multiple functional zones using protrusions arranged at different positions and heights. These protrusions create localized turbulence zones that enhance gas-liquid contact in specific regions, allowing extended contact time in mixing zones while maintaining clear separation in other zones, thus resolving the contradiction between solubility and separation efficiency
Solution Approach 2:
The protrusions are strategically positioned to create localized flow disturbances and extended contact paths in specific regions of the tank. This local modification of flow characteristics enhances gas dissolution where needed while preserving efficient separation in other areas, achieving both high gas solubility and effective gas-liquid separation
