Description

A bubble parameter measuring device

technical field

The utility model belongs to the technical field of water sample detection, in particular to a bubble parameter measuring device.

Background technique

The flow of oceans, rivers, and lakes will produce a large number of air bubbles, and the respiration and disturbance of underwater organisms will also produce a large number of air bubbles. The generation of air bubbles will affect the changes in oceans, rivers, lakes, and the external environment to a certain extent. Bubbles survive in water for several seconds to hundreds of seconds, and their main components are air, including O2, some CO2 and a small amount of toxic gases such as CO, SO2, CH4 and fluorocarbons. Studying the properties of bubbles plays an important role in fluid dynamics and material exchange, environmental noise, geophysics, chemical engineering applications, biopharmaceuticals, wastewater treatment, and environmental science.

Bubbles in oceans, rivers, and lakes are mainly produced by wave breaking, and their diameter generally does not exceed the millimeter level, so their shape is basically approximately circular. Acoustic scattering methods or optical photography methods are usually used to detect the distribution and particle size of bubbles. Among them, in the process of detecting bubble parameters using the acoustic scattering method, the required equipment structure is relatively simple and the detection is convenient, but it is greatly affected by environmental noise and the detection accuracy is low. Such as speed and particle size, etc.), it is difficult to achieve good results. The optical detection method is currently the main method used to study bubble parameters. The detection equipment is relatively complicated and the cost is high, but the imaging precision is high, and a very clear bubble image can be obtained. Through the processing of bubble images, detailed behavioral details can be provided for the attribute information of individual bubbles, and the movement characteristics of bubble groups can be analyzed through images with a certain time sequence, and the role of bubble breakup in gas exchange at the air-sea interface can also be studied. It can be used to study the movement of bubbles, calculate the heat and energy exchange on the interface between water and gas, correct the reflection error of underwater light field in sea color remote sensing, analyze the influence of bubbles on underwater acoustic noise, and survey the geological changes of the ocean, etc.
