Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ultra fine bubble generation apparatuses face inefficiencies in maintaining high concentrations of ultra fine bubbles due to recirculation, which reduces the generation efficiency and is problematic for applications requiring high-concentration bubbles.
Innovation Solution
The apparatus includes a circulation blocking configuration that prevents ultra fine bubbles from re-entering the generation unit, using electric field control or physical filters to separate and collect bubbles, thereby maintaining high concentrations in the output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a circulation mechanism is introduced to maintain ultra fine bubbles in the liquid, then the residence time of bubbles in the liquid is extended, but the generation efficiency decreases due to recirculation of already-generated bubbles
Solution Approach 1:
The circulation path is segmented into two separate paths: a first liquid passage that allows liquid to circulate back to the generation unit, and a second liquid passage that blocks bubbles from re-entering the generation unit. This segmentation resolves the contradiction by allowing liquid recirculation (maintaining residence time) while preventing bubble recirculation (maintaining generation efficiency).
Solution Approach 2:
The bubble-containing liquid is separated from the pure liquid in the circulation system. Bubbles are extracted from the circulation path through the blocking configuration (such as a bubble removal unit or separator), allowing only bubble-free liquid to return to the generation unit. This maintains high generation efficiency while still providing circulation benefits.
2Quantity of substance
If bubbles are allowed to recirculate with the liquid, then the concentration of bubbles in the liquid increases, but the generation efficiency decreases
Solution Approach 1:
The circulation system is divided into separate pathways for liquid and bubbles. The first liquid passage transports liquid back to the generation unit, while the second liquid passage (with blocking configuration) prevents bubbles from following the same path. This ensures that only de-bubbled liquid recirculates, maintaining high generation efficiency while allowing continuous operation.
Solution Approach 2:
Bubbles are discarded from the circulation path through the blocking configuration, preventing them from re-entering the generation unit. The liquid is recovered and reused in the circulation, maintaining system efficiency. This selective discarding of bubbles while recovering liquid resolves the contradiction between bubble concentration and generation efficiency.
