Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bubble generation devices are limited in their ability to simultaneously produce a large quantity of large bubbles effectively, particularly in confined spaces or when closely arranging planar or hollow-fiber-type separation membranes, leading to inefficient membrane washing and oxygen dissolution in reaction tanks.
Innovation Solution
A bubble generation device comprising a gas supply member, a bubble storing container with pivot and partitioning system that allows for continuous air supply and storage of bubbles, enabling the generation and release of large bubbles in a controlled and uniform manner, with edge portion receivers to manage the pivot and enhance bubble distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional air diffusing tubes or bubble storing plates are used to generate large bubbles, then some large bubbles can be produced, but the amount of large bubbles generated at the same time is limited
Solution Approach 1:
The bubble storing container is divided into multiple compartments by partitions, with each compartment independently storing bubbles. This segmentation allows simultaneous accumulation of large volumes of bubbles across multiple compartments, which can then be released together to generate a large quantity of large bubbles at once, significantly improving both the amount and productivity of bubble generation.
2Productivity
If planar or hollow-fiber-type separation membranes are closely arranged, then membrane separation efficiency is improved, but the distance between membranes becomes insufficient for effective bubble washing
Solution Approach 1:
Instead of relying on horizontal distance between membranes for bubble travel, the invention introduces vertical bubble generation from below the membranes. Bubbles are generated in a liquid phase beneath the closely-arranged membranes and rise upward, providing washing action from the opposite direction. This dimensional change allows membranes to be closely arranged horizontally while still maintaining effective washing through vertical bubble movement.
3Quantity of substance
If bubble storing containers are made larger to generate more large bubbles, then bubble quantity increases, but device complexity and installation difficulty increase
Solution Approach 1:
The bubble storing container is divided into multiple compartments by partitions, with each compartment independently storing bubbles. This segmentation allows the system to achieve large total bubble volume through multiple smaller compartments rather than one large complex container, simplifying the overall structure while maintaining high bubble generation capacity.
Solution Approach 2:
Multiple compartment structures are nested within the overall container framework, with partitions creating hierarchical organization. This nested arrangement maximizes bubble storage volume within a compact footprint, reducing the need for large external dimensions while maintaining high bubble generation capability.
4Quantity of substance
If air is continuously supplied to generate large bubbles, then oxygen dissolution increases, but oxygen-free conditions in reaction tanks cannot be maintained
Solution Approach 1:
The system uses periodic release of accumulated bubbles rather than continuous release. Bubbles are continuously generated and stored in the bubble storing container, then released in periodic large-volume batches. This periodic action allows control over the timing and volume of air introduction, enabling maintenance of oxygen-free conditions in reaction tanks while still providing sufficient oxygen dissolution during designated aeration periods.

AI summary
A bubble generation device intermittently generates large bubbles in a liquid phase. The bubble generation device includes a bubble storing container, a pivot, and a pair of edge portion receivers. The bubble storing container stores bubbles generated by a gas supply nozzle in the liquid. The pivot allows the bubble storing container to pivot thereon, thereby releasing the large bubbles from the bubble storing container. The pair of edge portion receivers receives and blocks an edge portion of the bubble storing container to limit pivot of the bubble storing container. An inside of the bubble storing container is partitioned by a partition that is installed in an axial direction of the pivot.
