[0033] Reference Figure 1-4, a micro-nano bubble sewage plant ozone catalytic oxidation lifting device, is used for ozone micro-bubble catalytic oxidation wastewater treatment, in order to make ozone and sewage fully contact and merge, to improve the ozone utilization rate and ozone catalytic oxidation effect.

[0034] The micro-nano bubble sewage plant ozone catalytic oxidation lifting device comprises a housing 1, a cooling box 13, a cooling pipe 9, a sewage spray pipe 10 and an aeration plate 12;

[0035] A water inlet pipe 2 and a water outlet pipe 6 are respectively provided on both sides of the shell 1. A catalyst layer is provided inside the shell 1, and the catalyst layer contains a hydrogel catalyst. A cooling box 13 is arranged at the bottom of the shell 1, and a coolant port 3 is provided outside the cooling box 13, through which coolant can be poured into the cooling box 13. A cooling pipe 9 is spirally coiled and arranged inside the cooling box 13. One end of the cooling pipe 9 is connected to the sewage inlet pipe 2, and the other end is connected to the sewage nozzle 10. The sewage enters the cooling pipe 9 through the water inlet pipe 2 and flows inside the cooling box 13 along the spirally coiled cooling pipe 9. The coolant inside the cooling box 13 can cool the sewage. The cooled sewage can improve the ozone dissolution effect, thereby improving the ozone utilization rate. One end of the sewage nozzle 10 penetrates into the shell 1, so as to discharge the cooled sewage into the shell 1.

[0036] The aeration plate 12 is arranged inside the shell 1. The aeration plate 12 is hollow cone-shaped. The upper end of the sewage nozzle 10 extends to the conical hollow interior of the aeration plate 12, so that the sewage is sprayed into the conical hollow interior of the aeration plate 12 and flows down along the conical inner wall of the aeration plate 12, thereby diverting the sewage. The aeration plate 12 is connected to the bubble generator through the bubble generator connecting pipe 5. The bubble generator connecting pipe 5 is provided with a solenoid valve 4. Ozone micro-nano bubbles are generated by the micro-nano bubble generator. Since the conical inner wall of the aeration plate 12 is provided with a plurality of bubble outlets 1201, the ozone micro-nano bubbles are discharged through each bubble outlet 1201, thereby mixing into the sewage that is diverted and flows down along the conical inner wall of the aeration plate 12 at this time. Since the diverted sewage flows down and mixes with the ozone micro-nano bubbles, the ozone and the sewage are fully in contact and fused, which can effectively improve the ozone utilization rate.

[0037] The center line of the aeration plate 12 coincides with the center line of the sewage nozzle 10, so that the sewage sprayed from the sewage nozzle 10 can flow evenly from the conical hollow top of the aeration plate 12 along the conical hollow inner wall. A guide plate 11 is provided on the outside of the upper end of the sewage nozzle 10. The guide plate 11 is conical, and the guide plate 11 is adapted to the conical hollow part of the aeration plate 12, so that the aeration plate 12 can be sleeved on the outside of the guide plate 11, and a gap is provided between the aeration plate 12 and the guide plate 11. The sewage sprayed from the sewage nozzle 10 can flow out from the gap between the aeration plate 12 and the guide plate 11, so that the ozone micro-nano bubbles discharged from the bubble outlet 1201 are mixed with the sewage in time, thereby improving the mixing effect of ozone and sewage.

[0038] A one-way valve 14 is provided at the upper end of the sewage spray pipe 10. The one-way valve 14 includes a moving plate 1401, a fixed plate 1402, a moving rod 1403, a spring 1404 and a limit plate 1405. The fixed plate 1402 is fixedly connected to the inside of the sewage spray pipe 10, and a through hole is opened in the middle of the fixed plate 1402. The moving rod 1403 is slidably connected to the inside of the through hole. The moving plate 1401 is fixedly connected to the upper end of the moving rod 1403. A water hole is opened on the fixed plate 1402 to allow sewage to pass through. The limit plate 1405 is fixedly connected to the lower end of the moving rod 1403. The spring 1404 is sleeved on the moving rod 1403. On the outside, the spring 1404 is located between the fixed plate 1402 and the limit plate 1405. The movable plate 1401 is in the shape of a circular plate and is located above the nozzle of the sewage nozzle 10. When sewage is discharged from the sewage nozzle 10, the movable plate 1401 will be pushed upward, and the movable plate 1401 will move upward, driving the movable rod 1403 and the limit plate 1405 to move upward. The spring 1404 is squeezed. At this time, the sewage sprayed from the nozzle of the sewage nozzle 10 will splash around through the circular plate-shaped movable plate 1401, so that the sewage flows evenly to the conical hollow inner wall of the aeration plate 12 to enhance the mixing effect of sewage and ozone.

[0039] In addition, to further increase the ozone dissolution effect;

[0040] A hydraulic cylinder 8 is provided at the top inner part of the shell 1, and a pressure plate 7 is provided at the lower end of the push rod of the hydraulic cylinder 8. The pressure plate 7 is pushed down by the push rod of the hydraulic cylinder 8. At this time, the pressure in the bottom space of the pressure plate 7 increases, and the movable plate 1401 moves downward and fits on the pipe mouth of the sewage nozzle 10. The one-way valve 14 at the pipe mouth of the sewage nozzle 10 is closed, and the pressure plate 7 moves downward to the bottom of the water outlet pipe 6, and the solenoid valve 4 is closed. A closed space is formed at the bottom of the pressure plate 7, which can apply pressure to the sewage inside the shell 1, thereby facilitating the integration of ozone into the sewage.

[0041] The working principle of the ozone catalytic oxidation lifting device of the micro-nano bubble sewage plant is as follows: sewage is poured through the water inlet pipe 2, and the sewage first enters the spirally coiled cooling pipe 9, and flows along the spirally coiled cooling pipe 9 inside the cooling box 13. The coolant inside the cooling box 13 can cool the sewage, and the sewage after cooling can improve the ozone dissolution effect, thereby improving the ozone utilization rate. Then the sewage is sprayed out through the nozzle of the sewage spray pipe 10. When spraying, the sewage will splash around through the circular plate-shaped moving plate 1401, so that the sewage The ozone micro-nano bubbles are uniformly flowed to the conical hollow inner wall of the aeration plate 12. At this time, the ozone micro-nano bubbles generated by the micro-nano bubble generator are discharged through each bubble outlet 1201, and then mixed into the sewage that is divided and flows down along the conical inner wall of the aeration plate 12. Since the sewage flows down and mixes with the ozone micro-nano bubbles, the ozone and the sewage are fully contacted and merged, which can effectively improve the ozone utilization rate and facilitate the treatment of the sewage with ozone. Subsequently, the sewage mixed with the ozone bubbles undergoes a catalytic oxidation reaction in the catalyst layer and is finally discharged through the outlet pipe 6.

[0042] During sewage treatment, the solenoid valve 4 can also be closed, so that the push rod of the hydraulic cylinder 8 pushes the pressure plate 7 down. At this time, the pressure in the bottom space of the pressure plate 7 increases, and the movable plate 1401 moves downward and fits on the pipe mouth of the sewage nozzle 10. The one-way valve 14 at the pipe mouth of the sewage nozzle 10 is closed, and the pressure plate 7 moves downward to the bottom of the outlet pipe 6. A closed space is formed at the bottom of the pressure plate 7, which can apply pressure to the sewage inside the shell 1, thereby facilitating the integration of ozone into the sewage.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
