Problems solved by technology

[0002] At present, in the floating seedbed breeding system, the water in the water bed is mostly static and has poor fluidity. The closely floating seedling tray on the surface of the water bed blocks the contact area between the water surface and the air, reduces the interaction area between water and air, and is affected by bacterial growth. , can easily lead to a decrease in dissolved oxygen in water
Low oxygen concentration and eutrophic water further accelerate the reproduction of facultative anaerobic and anaerobic bacteria, resulting in poor water quality, acidification and other problems, which ultimately affect the germination and growth of seedlings
[0003] The traditional methods of regional oxygenation and pump extracorporeal circulation have the following problems: first, the air bubbles are large, the specific surface area of ​​air-water contact is small, the water retention time is short, and the oxygenation effect is poor; second, the composition of water in the floating seedbed It is very complicated, and contains a lot of sand and stones and floating objects, which has a great erosion effect on the pump and poor system reliability; thirdly, both the circulating pump and the air pump need electric energy to drive, the system consumes a lot of energy, and the economic benefit is poor

specific Embodiment

[0038] Specific examples: such as figure 1 As shown, there can be one or more microbubble cyclone generators 2 . The air pump 22 selected according to the diameter of the oxygenation device 1 and the microbubble cyclone generator 2. The jet port 21 of the micro-bubble cyclone generator 2 is provided with a spoiler, which causes the passing gas to generate vortex disturbance, so that the micro-bubbles flowing out of the jet port 21 have spin characteristics. The spin of the microbubbles improves the air-water interaction on the surface of each bubble and improves the efficiency of dissolved oxygen. Simultaneously, the outlet position of the jet port 21 is arranged in the tangential direction of the side of the oxygenation device 1, so that the generated gas jet changes the flow direction under the action of the side of the oxygenation device 1, superimposed with the buoyancy of the bubbles, and in the floating seedbed pulsation oxygenation device A cyclone with a spiraling ch...
