Micro-Bubble Generator With Eddy Mixing for Fine Dense Bubbles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerators are unable to arbitrarily control the average volume of bubbles generated and have insufficient gas content, making it difficult to produce dense, fine bubbles for water purification and other applications.
Innovation Solution
A micro-bubble generator is designed to be integrated into a water outlet device, featuring a water inlet and outlet member with specific channel structures and features like gas inlet gaps, branching channels, and an eddy current guiding pipe to enhance gas inflow and bubble miniaturization, allowing for the generation of dense, fine bubbles without additional power sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the capacity of gas inlet pipe and water pressure of pump are increased to generate more bubbles, then the gas content increases, but the bubble volume becomes larger and less fine
Solution Approach 1:
The invention divides the single gas inlet into multiple gas inlet holes distributed across the gas inlet pipe wall. This segmentation allows gas to enter at multiple locations simultaneously, increasing total gas content while maintaining small bubble sizes through distributed injection points rather than a single large inlet
Solution Approach 2:
The patent creates different flow conditions at different locations within the mixing pipe by distributing gas inlet holes along the pipe wall. Each local region has optimized gas-liquid interaction characteristics, allowing fine bubbles to form throughout the entire mixing length rather than concentrating bubbles in one location
2Productivity
If the water pressure of pump is increased to maintain flow rate, then the water stream flow rate is maintained, but the bubble volume increases and gas content remains insufficient
Solution Approach 1:
The gas inlet pipe wall is divided into multiple gas inlet holes distributed along its length. This segmentation allows continuous gas injection throughout the mixing pipe, increasing total gas content without requiring higher pump pressure or reducing water flow rate
Solution Approach 2:
Instead of increasing gas flow in one dimension (single large inlet), the invention distributes gas injection across multiple dimensions by creating numerous small holes along the pipe wall, achieving higher gas content through spatial distribution rather than pressure increase
3Quantity of substance
If the capacity of gas inlet pipe is increased to generate more bubbles, then the gas content increases, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The invention changes the parameters of the gas inlet system by creating multiple small holes instead of one large hole. This parameter change (from single large aperture to multiple small apertures) increases gas content while using standard piping components that are easy to manufacture and install

AI summary
A micro-bubble generator is provided between an input end and an output end of a water outlet device. The micro-bubble generator includes a water inlet member and a water outlet member. A gas inlet gap is remained between the water inlet member and the water outlet member, with the gas inlet gap being communicated to external air, such that the external air is allowed to enter the micro-bubble generator for gas-liquid mixing and generate minute and dense bubbles.
