The aerator comprises a high-magnetism vortex-type ultrafine bubble generation cavity, a Venturi pipe, a controller, an oxygen gas source with a flow regulating valve, and a self-priming water pump, wherein the high-magnetism vortex-type ultrafine bubble generation cavity, Venturi pipe and controller are respectively electrically connected with the oxygen gas source; the input end of the Venturi pipe is respectively connected with the oxygen gas source and the self-priming water pump; and the output end of the Venturi pipe is connected with the water inlet of the high-magnetism vortex-type ultrafine bubble generation cavity. The aerator has the characteristics of compact structure, small occupied area, low energy consumption, high oxygen utilization, low cavitation corrosion, no blockage and the like, and can generate an N5 neodymium-iron-boron high-magnetism material with the magnetic field intensity of higher than 14500GS; and the volume of the output bubbles is lower than 10 mu m. The aerator is applicable to the field of in-water aeration, can be used instead of the traditional dissolved gas tank, and is suitable for sewage treatment, aquiculture and other water body oxygenation aeration or floatation separation and other water treatment techniques.

Description

technical field [0001] The present invention relates to a device in the technical field of water treatment, in particular to a bubble generation chamber and an aeration device with N5 NdFeB ferromagnetic material with a magnetic field strength above 14500 GS and an output bubble volume below 10 μm. Background technique [0002] The traditional bubble generator is under the action of external force, through the high-speed rotation of the impeller, the gas and liquid are strongly mixed and stirred, and the gas is broken into small bubbles. The bubbles generated by the traditional bubble generator are too large and consume a lot of energy. In addition, because the bubbles are too large, the residence time in the liquid is too short, which affects the dissolution of the gas. Therefore, the oxygenation effect is poor and the power consumption is high. [0003] Most of the current micro-bubble generators use a laser to drill countless small holes on the surface of the bubble gene...

Problems solved by technology

But the defect of this technology is that the oxygen in the air is first converted into this ozone, which does not increase the number of oxygen atoms in essence, and this practice has the potential risk of causing environmental pollution; in addition, due to the solubility of oxygen in water At the same temperature, it is proportional to the pressure. The device does not mention the device for pressurizing the container, that is to say, the sewage treatment process is under normal pressure, so it is not difficult to calculate the improvement of the dissolved oxygen in the water body. is very limited; third, the technology needs to use air compressors, ozone generators, water pumps, ionizers and many other electrical facilities, which has high energy consumption, high difficulty in system operation and maintenance, and the ozone generator and electric Ion generators are all high-voltage equipment, which poses a great safety hazard to operators and is not easy to install on water treatment equipment that is wet and prone to electric shock accidents; fourth, the flow path of the micro-bubble technology is M-type, although it increases the flow of water and gas. The residence time, but because it is an M type, the resistance to the gas-water mixture is large, resulting in a large power consumption; finally, because the technology does not provide an automatic control device, manual operation is required
