Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for measuring bubble size distribution in liquids containing fine bubbles struggle to accurately distinguish between fine bubbles and solid or liquid particles, and there is a need for an efficient technique to reduce fine bubbles in target liquids.
Innovation Solution
The method involves using ultrasonic waves with a frequency of 430 kHz or more to irradiate the target liquid, along with appropriate container positioning and standing time, to effectively reduce fine bubbles and measure their size distribution by comparing particle size distributions before and after ultrasonic treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a particle size distribution measuring device is used to measure fine bubbles in target liquid, then bubble size distribution can be measured, but fine bubbles cannot be distinguished from solid particles and liquid particles, resulting in inaccurate measurement
Solution Approach 1:
The patent applies preliminary action by eliminating fine bubbles from the target liquid before performing particle size distribution measurement. The ultrasonic irradiation device removes fine bubbles in advance, so that when the particle size distribution measuring device is used subsequently, only solid and liquid particles remain to be measured, eliminating the interference and enabling accurate measurement of particle size distribution without the confusion of distinguishing fine bubbles from particles.
2Productivity
If conventional ultrasonic frequencies are used to reduce fine bubbles, then some bubble reduction effect can be achieved, but fine bubbles cannot be efficiently reduced and may even increase in number
Solution Approach 1:
The patent applies parameter changes by specifically setting the ultrasonic wave frequency to 430 kHz or higher. This parameter change in the ultrasonic frequency ensures efficient and reliable reduction of fine bubbles. The specific frequency range is optimized to match the resonance characteristics of fine bubbles, ensuring consistent and effective elimination without the risk of increasing bubble numbers that can occur with conventional frequencies.
3Measurement precision
If fine bubbles are present in target liquid, then cleaning and sterilization effects can be achieved, but the presence of fine bubbles interferes with accurate particle size distribution measurement
Solution Approach 1:
The patent applies the taking out principle by extracting and removing fine bubbles from the target liquid using ultrasonic irradiation before particle size distribution measurement. This separation removes the harmful interfering factor (fine bubbles) from the measurement system, allowing the particle size distribution measuring device to accurately measure only the solid and liquid particles in the liquid without interference from fine bubble signals.
