Light filament induced micro-nano bubble generation device

Abstract

The invention relates to a light filament induced micro-nano bubble generation device. A laser light source device comprises a light source part and a laser focusing part. That laser light emitted bythe light source part is focused by the laser focusing part and then a plasma light filament is formed in a laser light filament part through a beam control device. The laser light filament part adopts that nanometer metal particles are uniformly doped in that solution, after the laser produces light filaments in the solution, a supercontinuous spectrum is generated in that solution, the nano metal particle surface plasmas are subjected to resonance excitation by supercontinuous spectrum, a liquid solution is instantaneously gasified at a rapid rise in temperature, so that a large number of cluster-like micro-nano bubbles are formed, a scanning and detecting device in the bubble imaging section is connected to an imaging display device by a computer, a feedback control unit sets the laserpower parameter by the control software, and feeds back the bubble size data detected by the analysis scanning detection device to the beam control device, and adjusts the power of the laser by the beam control device to change the bubble size, density, and generation rate.

Description

technical field [0001] The invention relates to a device for generating micro-nano bubbles, in particular to a device for generating micro-nano-bubbles induced by light filaments. Background technique [0002] Micro-nano bubbles are bubbles with a diameter of 1 nm to 600 nm. Because micro-nano bubbles solve the problems of low gas dissolution rate and low solubility, they have application prospects in the fields of water treatment, food processing cleaning and disinfection. In terms of water pollution treatment, micro-nano bubble technology is a high-end water environment treatment technology integrating air flotation, filtration, disinfection and dissolved oxygen in water environment treatment. It can speed up the oxidation and decomposition of organic pollution in water bodies, and cooperate with appropriate horizontal direction The advanced water body stirring device can expand the distribution range of micro-nano bubbles in the horizontal direction, fully mix with the s...

Problems solved by technology

However, for the nanobubbles formed by compression, the yield of nanobubbles generated by this method is limited, which is 10 6 pieces / minute, the actual process requires a higher bubble production rate to improve cleaning / processing efficiency

At the same time, because the surface of the nanobubbles prepared by the traditional method has no special electrical properties, it is easy to agglomerate and the bubbles do not last long.

Moreover, in the actual process, nanobubbles are needed to clean the metal surface, but the oxygen in the compressed air can easily cause the oxidation of the metal material, so the application prospect is limited.
