Continuous spectrum bubble generator and manufacturing method of continuous spectrum bubble

Abstract

The invention provides a continuum bubble generator and a method for making continuum bubbles, comprising a bubbling device and a crushing device, the bubbling device is connected to the crushing device, and the bubbling device is used to generate a bubble flow; the crushing device includes a crushing chamber The broken parts are set in the crushing cavity, and the broken parts rotate continuously under the action of the driving parts, and the rotating speed of the broken parts can be controlled by the driving parts; water is supplied to the air bubble generation pipe through the auxiliary water supply pipe, and the Air is conveyed in the porous pipe to form a bubble flow; multiple main water supply pipes feed water and form a flow field to initially cut the bubble flow. It is broken under the action of the parallel shear flow field, and the bubble flow flows in the crushing cavity along its circumferential direction, and the broken bubble flow flows out of the crushing cavity through the finished product outlet pipe to obtain the finished product. It is helpful to obtain continuous spectrum bubbles, and the operation is simple.

Description

technical field [0001] The invention relates to the technical field of making micro-nano bubbles, in particular to a continuum bubble generator and a method for making continuum bubbles. Background technique [0002] Gas-liquid two-phase bubbly flow is one of the important two-phase flow, which has important applications in the fields of energy, power, chemical industry and aerospace. In addition, micro-nanobubbles play an extensive and important role in environmental engineering, nuclear science and other fields due to their excellent physical properties. [0003] At present, the mechanisms of bubble-induced turbulent flow and bubbly heat and mass transfer are still unclear, which limits the further application of gas-liquid two-phase flow in scientific research and engineering. In order to study its mechanism, it is necessary to establish the relationship between the bubble size distribution spectrum and each experimental object, realize active research, and break through...

AI Technical Summary

Problems solved by technology

[0005] The inventor believes that there are many types of millimeter, micron, and nanoscale bubble generators, but most devices can only generate bubbles with a single size or a non-concentrated size distribution.

Individual devices can obtain bubbles of a specific size, and due to the limitations of the selected bubble generation principle and the difficulty of adjusting parameters, it is difficult to obtain a bubble spectrum whose size can change continuously in a wide range
