Description

Technical Field

[0001] The utility model relates to the technical field of nano-bubble water generation, and specifically relates to a nano-bubble water generation device. Background Art

[0002] Nano-bubble water refers to water containing a large number of bubbles with diameters in the nanoscale range (usually less than 200 nanometers). These tiny bubbles have unique physical and chemical properties compared to traditional bubbles. Nano-bubbles have the characteristics of relatively increased surface area, slower rising speed, automatic pressure increase and dissolution, surface charging, and generation of ·OH free radicals. Nano-bubble water can increase the dissolved oxygen content of water, improve water quality, and is widely used in fields such as sewage treatment and river water quality improvement.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, as Figures 1 - 3 shown, a nano-bubble water generating device includes a housing 1. A partition 4 is fixedly arranged inside the housing 1. The partition 4 divides the interior of the housing 1 into an electric control chamber 2 and a nano-bubble water generating chamber 3. A total water inlet pipe 7 is fixedly arranged in the mounting hole on one side of the nano-bubble water generating chamber 3. A total water outlet pipe 13 is fixedly arranged in the mounting hole on the other side of the nano-bubble water generating chamber 3. The total water outlet pipe 13 and the total water inlet pipe 7 are coaxially arranged. A nano-bubble generating component is arranged between the total water inlet pipe 7 and the total water outlet pipe 13. The nano-bubble generating component includes a nano-generator body 8. The nano-generator body 8 has a generator water inlet end 9, a generator gas inlet end 11 and a generator water outlet end 12. The generator water outlet end 12 is communicated with the input end of the total water outlet pipe 13. A first control mechanism for controlling the liquid flow rate is arranged between the generator water inlet end 9 and the output end of the total water inlet pipe 7. A transmission pipe is communicated at the generator gas inlet end 11. The other end of the transmission pipe is provided with a total gas inlet pipe 10 in cooperation. A second control mechanism for controlling the gas flow rate is arranged between the total gas inlet pipe 10 and one end of the transmission pipe. The first control mechanism facilitates controlling the liquid flow rate of the liquid entering the nano-generator body 8, and the second control mechanism facilitates controlling the gas flow rate of the gas entering the nano-generator body 8;

[0025] An touch display screen 5 and electric control buttons 6 are arranged inside the electric control chamber 2. Both the touch display screen 5 and the electric control buttons 6 are electrically connected to a control component. The control component is fixedly arranged inside the electric control chamber 2. The nano-generator body 8 is electrically connected to the control component. During use, it is convenient to control and adjust the whole generating device. It should be noted that in this application, the control component, the touch display screen 5 and the electric control buttons 6 all adopt existing components. The specific working pressure and control method are common knowledge and will not be elaborated here.

[0026] The first control mechanism includes a water inlet regulating valve 14. The input end of the water inlet regulating valve 14 is communicated with the output end of the total water inlet pipe 7. The output end of the water inlet regulating valve 14 is communicated with the generator water inlet end 9. The water inlet regulating valve 14 is electrically connected to the control component. During use, when it is necessary to adjust the liquid flow rate at the generator water inlet end 9, the water inlet regulating valve 14 can be controlled through the touch display screen 5 and the control component, and then the flow rate at the generator water inlet end 9 can be adjusted.

[0027] The second control mechanism includes an intake air regulating valve 18. The input end of the intake air regulating valve 18 is connected to the output end of the main intake pipe 10, and the output end of the intake air regulating valve 18 is connected to the input end of the transfer pipe. The intake air regulating valve 18 is electrically connected to the control component. During use, when it is necessary to adjust the intake air volume at the intake end 11 of the generator, the intake air regulating valve 18 can be controlled through the touch display screen 5 and the control component, thereby adjusting the gas flow rate at the intake end 11 of the generator.

[0028] An intake water flowmeter 15 and a pressure gauge 16 are installed on the main outlet pipe 13, and an intake air flowmeter 17 is installed on the transfer pipe. The intake water flowmeter 15, the pressure gauge 16, and the intake air flowmeter 17 are all electrically connected to the control component. During use, it is convenient to timely monitor the magnitudes of the flow rates and pressures at various locations, and then make adjustments.

[0029] Both the outer casing 1 and the partition plate 4 are made of stainless steel. During use, it reduces rust and increases the service life.

[0030] The cross-sectional area between the water inlet end 9 of the generator and the middle of the nano generator body 8 is tapered, and the cross-sectional area between the middle of the nano generator body 8 and the water outlet end 12 of the generator is flared. The middle of the nano generator body 8 is the throat tube, and the throat tube is double-layered. An air distribution chamber 19 is provided inside the throat tube. The middle of the throat tube is a water pipe, and a number of air distribution holes 20 are arranged in an array on the pipe wall of the water pipe. A flow groove 21 is provided on the inner wall of the water pipe. During use, the nano generator body 8 is divided into three parts. The water inlet end is tapered, the middle part is the throat tube, and the rear part is flared. The cross-section between the water inlet end 9 of the generator and one end of the nano generator body 8 is frustum-shaped. The vertical cross-sectional diameter at the water inlet end 9 of the generator is larger than the vertical cross-sectional diameter at one end of the nano generator body 8, so that the cross-sectional area between the water inlet end 9 of the generator and the middle of the nano generator body 8 is tapered. Similarly, the cross-section between one end of the nano generator body 8 and the water outlet end 12 of the generator is frustum-shaped. The vertical cross-sectional diameter at one end of the nano generator body 8 is smaller than the vertical cross-sectional diameter at the water outlet end 12 of the generator, so that the cross-sectional area between the middle of the nano generator body 8 and the water outlet end 12 of the generator is flared. When the liquid enters from the water inlet end 9 of the generator, the water flow velocity will become faster and faster. When the liquid reaches the throat tube, the velocity reaches the maximum value. At this time, the inlet energy is mainly kinetic energy and the static pressure tends to zero. At the same time, on the one hand, the liquid generates a strong negative pressure and sucks in the gas through the gas inlet end 11 of the generator. On the other hand, the sucked gas is under the high-speed impact and shear of the rotating forward water flow when flowing through the throat tube, and nano bubbles and micro bubbles will be generated. When the water flows out of the throat tube and enters the rear flared pipe, the water flow velocity suddenly decreases, generating violent turbulence, further shearing the bubbles in the water into nano bubbles and micro bubbles with smaller sizes. The generated bubbles are mainly nano bubbles and a small amount of micro bubbles, which are formed by the combination of high-speed swirling cutting and the gradual reduction and sudden expansion of the cross-sectional area. Most of the generated bubbles will be converted into nano bubbles, with high gas utilization rate, gas-liquid ratio > 30%, and density exceeding 500 million / mL.

[0031] The above embodiments disclose a nano-bubble water generating device. Among them, at the end of the reaction tank, part of the wastewater is pumped to the total inlet pipe 7 of the device by a lift pump, and then enters the generator water inlet end 9 of the nano-generator body 8. Air or ozone enters the generator air inlet end 11 of the nano-generator body 8 through the total air inlet pipe 10 of the device. The gas and water undergo high-speed swirling cutting and gradually shrinking and expanding cross-sectional area in the nano-generator body 8, generating a large amount of nano-bubble water, which is discharged from the generator water outlet end 12 of the nano-generator body 8 to the front end of the reaction tank through the total outlet pipe 13 of the device, aerating and oxygenating the wastewater or opening the rings, breaking the chains, changing the structure of complex, toxic and harmful organic substances in the wastewater, improving the biodegradability of the wastewater, and degrading the refractory substances in the wastewater. An inlet regulating valve 14 is installed on the inlet pipe of the nano-generator body 8, an inlet flowmeter 15 and a pressure gauge 16 are installed on the total outlet pipe 13, and an air inlet flowmeter 17 and an air inlet regulating valve 18 are installed on the transfer pipe. These instruments are installed to adjust the flow rates of water inlet and air inlet timely and accurately.

[0032] As described above, the above are only the specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
