Description

Technical Field

[0001] The utility model belongs to the technical field of secondary water supply water treatment, and particularly relates to a micro-nano bubble generating device with switchable gas sources and a micro-nano bubble disinfection cabinet. Background Art

[0002] Using micro-nano bubble technology to disinfect drinking water is a new method for drinking water treatment. Micro-nano bubbles are a type of tiny bubbles with diameters in the micrometer and nanometer ranges. Compared with traditional bubbles, they have the characteristics of small volume, large specific surface area, long existence time, good mass transfer efficiency, high surface potential, strong biological activity, and the ability to generate free radicals. In recent years, micro-nano bubbles have attracted great attention due to their outstanding characteristics. Research shows that the removal rates of micro-nano bubble water for difficult-to-degrade impurities such as phenol, trichloroethylene, and butylated hydroxytoluene can all reach over 80%. If the reaction time is sufficient, the total removal rate of trichloroethylene can even reach 99%. The ·OH generated by micro-nano bubbles can effectively control various impurities and microorganisms in water. Compared with other methods of generating ·OH, the ·OH generated by micro-nano bubbles is generated during their rupture process. Therefore, using micro-nano bubbles to disinfect drinking water is simple and clean, providing more guarantees for drinking water safety and meeting environmental protection requirements at the same time.

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0032] In order to conveniently and efficiently generate micro-nanobubbles, the present utility model provides a micro-nanobubble generating device with a switchable air source and a micro-nanobubble disinfection cabinet.

[0033] The micro-nanobubble generating device with a switchable air source includes a gas generating and switching mechanism and a gas-liquid mixing mechanism. Refer to Figures 1 to 2 .

[0035] The air pump 14 is connected to a gas-liquid separator 16, and the gas-liquid separator 16 is connected to an ozone generator 15. The compressed air generated by the air pump 14 enters the ozone generator 15 through the gas-liquid separator 16.

When the pressure in the gas storage tank 17 reaches 0.2 MPa, the electric contact pressure gauge 18 transmits a pressure signal to the electronic control component 13, so that the electronic control component 13 controls the air pump 14 to stop operating.

[0037] The gas-liquid mixing mechanism includes a gas-liquid mixing pump 23 controlled by the electronic control component 13; A gas storage tank air supply solenoid valve 21 is arranged on the gas storage tank 17, and the gas storage tank air supply solenoid valve 21 is controlled by the electronic control component 13. The electronic control component 13 sends a signal to make the gas-liquid mixing pump 23 operate and open the gas storage tank air supply solenoid valve 21.

[0038] The gas storage tank 17 is connected to the gas-liquid mixing pump 23 through a gas flow meter 26. After the gas storage tank air supply solenoid valve 21 is opened, the gas in the gas storage tank 17 flows into the gas-liquid mixing pump 23 through the gas flow meter 26.

[0039] The gas-liquid mixing pump 23 is connected to a water inlet pipe 9, and water flows into the gas-liquid mixing pump 23 through the water inlet pipe 9.

[0040] The gas-liquid mixing pump 23 is connected to a gas dissolving chamber 24, an exhaust valve 25 is arranged on the gas dissolving chamber 24, and the excess gas in the gas dissolving chamber 24 is discharged through the exhaust valve 25.

[0041] The gas dissolving chamber 24 is connected to a water outlet pipe 10, a micro-nano bubble generator 27 is arranged on the water outlet pipe 10, and when the water mixed with gas is discharged through the water outlet pipe 10, it is converted into micro-nano bubble water by the micro-nano bubble generator 27.

[0042] To solve the problems existing in the prior art, the present utility model further proposes a micro-nano bubble disinfection cabinet, refer to Figure 3 、 Figure 4 ; It includes a main body frame 1, the main body frame 1 is of a cuboid structure, and a horizontal partition plate 19 is arranged in the middle, dividing the main body frame 1 into upper and lower double-layer spaces.

[0043] Sealing plates 2 are respectively arranged on the top surface and the bottom surface of the main body frame 1; An electrical maintenance door 5 is hinged to the upper part of one side of the main body frame 1, and a water pump maintenance door 6 is hinged to the lower part; An industrial control screen 3 and control buttons 4 are installed on the electrical maintenance door 5 for monitoring the electronic control component 13; An air source maintenance door 7 is hinged to the upper part of the opposite side of the main body frame 1 to the electrical maintenance door 5, and a gas tank maintenance door 8 is hinged to the lower part, which is convenient for maintaining each device in the device.

[0045] Rollers are bolted to the bottom surface of the sealing plate 2 at the bottom of the main frame 1, facilitating the movement of this device.

[0046] The following introduces the working process of this micro-nano bubble disinfection cabinet:

[0047] First, move this micro-nano bubble disinfection cabinet to the required position;

[0048] Second, gas source preparation: When the pressure in the gas storage tank 17 is less than 0.1 MPa due to gas release, the electronic control component 13 will send a signal to make the air pump 14 operate and output compressed air; the compressed air enters the ozone generator 15 through the gas-liquid separator 16. The ozone generator 15 will not generate ozone gas in the non-powered state and only serves as a gas passage; the compressed air enters the booster valve, and the booster valve starts. When the pressure in the gas storage tank 17 rises to 0.2 MPa, the electric contact pressure gauge connected to the gas storage tank 17 stops the air pump operation through the electronic control component 13, and at this time, the gas source preparation is completed.

[0049] Finally, gas-liquid mixing to generate nano-bubbles: The electronic control component 13 sends a signal to make the gas-liquid mixing pump 23 operate. At the same time, the gas storage tank 17 and the gas supply solenoid valve 21 of the gas storage tank are opened. Water flows into the gas-liquid mixing pump 23 through the water inlet pipe 9, and the gas in the gas storage tank 17 flows into the gas-liquid mixing pump 23 through the gas flow meter 26. The water and gas are mixed by the gas-liquid mixing pump 23 and flow into the dissolved air chamber 24. The mixture of gas and water passes through the dissolved air chamber 24, and the excess gas is discharged through the exhaust valve 25, and then flows into the water outlet pipe 10, and micro-nano bubble water is generated through the micro-nano bubble generator 27.

[0050] According to the water quality situation to be purified, if ozone micro-nano bubble water needs to be generated, during the gas source preparation process, the ozone generator 15 is powered on, and the ozone generator 15 can generate ozone; the ozone generated by the ozone generator 15 enters the gas storage tank 17 for use. In this process, the ozone generator 15 can not only serve as a gas passage for the gas source but also provide ozone for the device, realizing the free switching of the micro-nano bubble water gas source.

[0051] It should be noted that all the equipment used in this device belongs to the prior art and will not be elaborated here.

[0052] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
