Description

Technical Field

[0001] The utility model belongs to the technical field of dissolved air, and in particular relates to an ozone micro-nano high-efficiency dissolved air system. Background Art

[0002] Advanced oxidation technology is an emerging technology in the field of wastewater treatment in recent years. It usually refers to a treatment method that produces highly reactive hydroxyl radicals (-OH) under certain ambient temperature and pressure to oxidize and degrade difficult-to-degrade organic pollutants that are difficult to be degraded by general oxidants. Ozone advanced oxidation technology has great advantages in advanced oxidation technology. Whether pollutants in wastewater can be effectively and completely degraded depends on the dissolved concentration of ozone in water. Micro-nano bubble technology, through its unique physical properties, provides an effective means to improve the solubility and oxidation efficiency of ozone in water treatment.

[0003] There are many ways to generate micro-nano bubbles. The following are some common ways:

[0004] Pressurized dissolution method: The gas is forced to dissolve in water under high pressure, and then released under reduced pressure to produce micro-nano bubbles with a diameter of 10 to 100 μm. This method can produce a large number of bubbles with uniform particle size distribution, and is often used in flotation technology.

[0005] Gyratory shear method: utilizes the effects of rotation and shear force to produce micro-nano bubbles under certain conditions.

[0006] Electrochemical method: Through the process of electrolysis of water, hydrogen and oxygen bubbles with a diameter of about 20μm are produced on the electrode surface. Iron or aluminum is usually used as the electrode.

[0007] Ultrasonic cavitation method: Use the pressure change caused by ultrasound in the liquid to produce a cavitation effect, thereby forming micro-nano bubbles.

[0008] Mixed jet method: Micro-nano bubbles are generated by mixing different fluids and applying high-speed jets.

[0009] Microporous pressurization method: using microporous materials to generate micro-nano bubbles under pressurized conditions.

[0010] The inventors have found that when using microporous materials to generate micro-nano bubbles, the fixed placement of the microporous materials will lead to uneven distribution of the generated micro-nano bubbles, thereby affecting the dissolution of ozone in the liquid, thereby affecting the overall treatment efficiency.

[0011] In view of the existing structure and deficiencies, research and improvement are carried out to provide an ozone micro-nano high-efficiency dissolved gas system in order to achieve a more practical purpose. Utility Model Content

[0031] Example 1, please refer to Figure 1 and Figure 2 An ozone micro-nano high-efficiency dissolved gas system comprises an dissolved gas tank 1 and an ozone generator. The dissolved gas tank 1 is provided with a rotatable rotating shaft 21, and the rotating shaft 21 is provided with a plurality of fixedly connected support rods 22. The support rods 22 are provided with dissolved gas columns 2, and the dissolved gas columns 2 are provided with micropores 20. The output end of the ozone generator is connected with the micropores 20 on the dissolved gas column 2 through a pipeline, and the dissolved gas column 2 is provided with a sleeve 23 which can move up and down and is used for cleaning the micropores 20.

[0032] The combination of the ozone generator and the micropores 20 on the dissolved air column 2 can form micro-nano bubbles in the dissolved air tank 1, and the ozone can be more efficiently dissolved in water in the form of micro-nano bubbles. The design of the rotating shaft 21 and the multiple dissolved air columns 2 can make the ozone distribution in the dissolved air tank 1 more uniform; the design of the sleeve 23 can utilize the up and down movement of the sleeve 23 to clean the micropores 20 on the surface of the dissolved air column 2, which can effectively prevent the clogging of the micropores 20.

[0033] In this embodiment, a water inlet pipe 12 is provided at one end of the gas dissolving tank 1, and a water outlet pipe 13 is provided at the other end of the gas dissolving tank 1. A fixedly connected driving motor 11 is provided on the gas dissolving tank 1, and the output end of the driving motor 11 is connected to a rotating shaft 21. A supporting base 14 is provided at the bottom of the gas dissolving tank 1 above the water outlet pipe 13, and the rotating shaft 21 is rotatably connected to the supporting base 14.

[0034] In this embodiment, an adjusting tube 26 that can move up and down is provided on the rotating shaft 21, a fixed rod 24 connected to the adjusting tube 26 and the sleeve 23 is provided, and a limiting ring groove with a convex cross-section is provided on the adjusting tube 26 at the uppermost end, and a matching and slidably connected limiting ring plate 28 is provided in the limiting ring groove, and a fixedly connected hydraulic rod 25 is provided in the gas dissolving tank 1, and the bottom of the hydraulic rod 25 is fixedly connected to the limiting ring plate 28, and a synchronous rod 27 connected is provided between adjacent adjusting tubes 26.

[0035] The design of the limiting ring plate 28, the limiting ring groove and the hydraulic rod 25 can utilize the telescopic movement of the hydraulic rod 25 to achieve the synchronous up and down movement of multiple adjusting tubes 26, and since the limiting ring plate 28 is rotatably connected to the limiting ring groove, the up and down movement of the hydraulic rod 25 will not affect the rotation of the adjusting tube 26, thereby ensuring the overall stable operation.

[0036] In this embodiment, a plurality of fixedly connected brush wires 29 are provided on the inner wall of the sleeve 23 .

[0037] The design of the brush wire 29 can make the cleaning of the micropores 20 more thorough.

[0038] In this embodiment, a first hollow groove is provided inside the rotating shaft 21, a second hollow groove connected to the first hollow groove is provided inside the supporting rod 22, an air inlet groove connected to the second hollow groove is provided on the dissolved air column 2, a plurality of air inlet holes connected to the micropores 20 are provided on the air inlet groove, and a guide tube is provided at the output end of the ozone generator, and the extension end of the guide tube is connected to the first hollow groove.

[0039] When using this application:

[0040] First, the ozone generator is started, and the ozone generated by the ozone generator enters the dissolved gas column 2 through the guide tube after being pressurized, and then enters the micropore 20 through the air inlet hole and is discharged. The ozone passing through the micropore 20 forms micro-nano bubbles in the dissolved gas tank 1, so that the ozone is dissolved in the liquid in the dissolved gas tank 1;

[0041] At the same time, the driving motor 11 is started to drive the rotating shaft 21 to rotate, so that the multiple dissolved gas columns 2 can rotate in the dissolved gas tank 1, so that the ozone distribution is more uniform;

[0042] When the micropores 20 are blocked, the sleeve 23 can be driven to move up and down by controlling the hydraulic rod 25 to extend and retract, and the brush wire 29 in the sleeve 23 can be used to clean the micropores 20 to prevent the micropores 20 from being blocked.
