[0038] Please refer to Figures 1 to 10: Example

[0039] The present invention provides a micro-nano bubble ozone catalytic oxidation reaction device, comprising: a reaction box 1;

[0040] The reaction box 1 is a rectangular box-shaped structure, with a cover plate 101 fastened to the top of the reaction box 1. A sewage pipe 102 for adding sewage is provided on the cover plate 101. An additive pipe 103 for adding additives is also provided on the cover plate 101.

[0041] Among them, the stirring part 2 is composed of a first mounting block 201, a first motor 202, a first threaded rod 203, a stirring plate 204 and a first through hole 205. The first mounting block 201 is fixed to the left end face of the inner wall of the reaction box 1. The first mounting block 201 is a rectangular block structure. A first motor 202 is fixed to the right end face of the first mounting block 201. A first threaded rod 203 is installed on the rotating shaft of the first motor 202. The upper thread of the first threaded rod 203 is connected to a stirring plate 204. The stirring plate 204 is a rectangular plate structure. The front end face of the stirring plate 204 The rear end surface contacts the front end surface and the rear end surface of the reaction box body 1 respectively. When the stirring plate 204 is provided with a first through hole 205 in a linear array, the first through hole 205 is a rectangular hole structure. When it is necessary to mix the sewage and the additive, the first motor 202 can be controlled to rotate reciprocatingly. When the first motor 202 rotates reciprocatingly, it can drive the first threaded rod 203 to rotate reciprocatingly. Under the thread drive of the first threaded rod 203, the stirring plate 204 moves back and forth in the reaction box body 1. When the stirring plate 204 moves back and forth, it can complete the mixing of the sewage and the reagent in the reaction box body 1.

[0042] Among them, a gas mixing part 3 is installed in the reaction box body 1. The gas mixing part 3 consists of an injection pipe 301, a connecting pipe 302 and an air outlet 303. The injection pipe 301 is fixed inside the reaction box body 1. The injection pipe 301 is a U-shaped structure. A connecting pipe 302 is connected to the injection pipe 301, and the connecting pipe 302 is connected to an external gas supply device; the injection pipe 301 is provided with air outlets 303 in a circular array. The air outlet holes 303 opened in the circular array together constitute the diffusion injection structure of the connecting pipe 302.

When the stirring plate 204 moves left and right, the air outlet 303 on the air jet pipe 301 is in a continuously blocked state. When gas decomposition is needed, the air supply pump can be directly controlled to work. At this time, the air supply pump transports the gas to the air jet pipe 301 through the connecting pipe 302, and then sprays it out through the air outlet 303. The gas sprayed from the air outlet 303 contacts the sewage to achieve sewage mixing treatment; at the same time, the first motor 202 drives the stirring plate 204 to move back and forth to stir to achieve sewage and agent mixing. At the same time, the size of the air outlet 303 can be adjusted by the continuous blocking of the air outlet 303 by the stirring plate 204. When the air outlet 303 is blocked, the air outlet 303 becomes smaller. When the air outlet 303 becomes smaller, the gas spray distance will increase, and the spray distance adjustment is automatically achieved, thereby improving the sewage treatment effect.

[0044] Among them, an auxiliary part 4 is installed in the reaction box body 1, and the auxiliary part 4 is composed of an auxiliary plate 401, a second through hole 402 and a protrusion 403.

The auxiliary plate 401 is located below the sewage pipe 102. The auxiliary plate 401 is provided with a second through hole 402 in a rectangular array. The second through hole 402 is a circular hole structure. The second through holes 402 opened in a rectangular array together constitute a filtering structure for impurities in sewage.

[0045] Among them, the bottom end surface of the auxiliary plate 401 is welded with a linear array of protrusions 403, and the protrusions 403 are a semi-cylindrical structure. The top surface of the stirring plate 204 contacts the bottom end surface of the auxiliary plate 401. The top surface of the stirring plate 204 is polished. After polishing, the top surface of the stirring plate 204 is an arc-shaped structure. When the stirring plate 204 moves left and right, the top surface of the stirring plate 204 is in a continuous elastic contact state with the protrusions 403. At this time, the auxiliary plate 401 is in a continuous lifting state. When in use, the sewage contacts the auxiliary plate 401. At this time, under the action of the second through hole 402, the sewage can be filtered. At the same time, when the stirring plate 204 moves left and right to achieve sewage mixing, it can squeeze the protrusions 403, and the up and down movement of the auxiliary plate 401 is realized. When the auxiliary plate 401 moves up and down, the sewage in the reaction box 1 can be mixed again, and the contact effect with the sewage, the reagent and the decomposition gas in the reaction box 1 can be improved, thereby improving the sewage treatment effect.

[0046] Among them, the shielding part 5 is installed on the cover 101, and the shielding part 5 is composed of a spring rod 501 and a shielding block 502. The bottom end surface of the cover 101 is welded with a spring rod 501 in a rectangular array.

The shielding blocks 502 are rectangular block structures. The shielding blocks 502 are aligned with one side of the second through hole 402. When the shielding blocks 502 contact the second through hole 402, the second through hole 402 The right half of 02 is in a blocked state, and the distance between the blocking block 502 and the second through hole 402 is smaller than the radius of the protrusion 403. When the stirring plate 204 pushes the protrusion 403 to move upward, the second through hole 402 contacts the blocking block 502. At this time, the right half of the second through hole 402 is blocked. When the auxiliary plate 401 continues to move upward, the downward jet flow rate at the second through hole 402 will increase, which can improve the contact effect between the sewage and the decomposition agent and the decomposition gas in the reaction box 1. Example

[0047] The present invention provides a micro-nano bubble ozone catalytic oxidation reaction device, which also includes: a lifting part 6, which is installed on the reaction box 1. The lifting part 6 is composed of a connecting block 601, a second mounting block 602, a second motor 603, a second threaded rod 604 and a locking screw 605. There are two second mounting blocks 602, which are respectively welded to the left end face and the right end face of the reaction box 1.

When the two second motors 603 rotate, they can drive the two second threaded rods 604 to rotate. At this time, the cover 101 can be lifted under the drive of the two second threaded rods 604. After the cover 101 is lifted, it is convenient to maintain and clean the structure inside the reaction box 1; when the second motor 603 is damaged, the two locking screws 605 are directly loosened, and then the cover 101 can be manually removed. Example

[0049] The present invention provides a micro-nano bubble ozone catalytic oxidation reaction device, which also includes: a discharge part 7, which is provided on a reaction box 1. The discharge part 7 is composed of a sleeve 701, a discharge pipe 702, a valve 703, a discharge hole 704 and a block 705. The sleeve 701 is provided on the right end surface of the reaction box 1. The sleeve 701 is a cylindrical tubular structure. A discharge pipe 702 is connected to the sleeve 701 through an internal thread. The discharge pipe 702 is a cylindrical tubular structure. A valve 703 for controlling the on-off of the discharge pipe 702 is installed on the discharge pipe 702.

[0050] Among them, the outer wall of the discharge pipe 702 is provided with discharge holes 704 in a circular array on the left side. The discharge holes 704 are circular hole structures. The discharge holes 704 are in contact with the inner wall of the sleeve 701. At this time, the discharge holes 704 are in a sealed state. When the discharge holes 704 move to the left and separate from the sleeve 701, the discharge holes 704 are in a non-blocked state.

[0051] Among them, a stopper 705 is welded to the left end face of the discharge pipe 702. The stopper 705 is a circular plate structure. The right end face of the stopper 705 contacts the left end face of the sleeve 701. The stopper 705 and the sleeve 701 together constitute the sealing structure of the discharge pipe 702. When it is necessary to discharge sewage, the discharge pipe 702 is first rotated. At this time, the discharge pipe 702 moves to the left, and the sewage can enter the discharge pipe 702 through the discharge hole 704, and then the valve 703 is opened. After the discharge is completed, the valve 703 needs to be closed. At this time, if the valve 703 is damaged and cannot be closed, the discharge pipe 702 is directly rotated in the opposite direction, and the discharge pipe 702 moves to the left. At this time, the discharge hole 704 is hidden inside the sleeve 701, and the stopper 705 contacts the left end face of the sleeve 701 to complete the sealing of the discharge pipe 702.

[0052] Working principle: First, the sewage is injected into the interior through the sewage pipe 102. When it is necessary to mix the sewage with the additive, the first motor 202 can be controlled to rotate back and forth. When the first motor 202 rotates back and forth, it can drive the first threaded rod 203 to rotate back and forth. Under the thread drive of the first threaded rod 203, the stirring plate 204 moves back and forth in the reaction box 1. When the stirring plate 204 moves back and forth, it can complete the mixing of the sewage and the reagent in the reaction box 1; when gas decomposition is required, the air supply pump can be directly controlled to work. At this time, the air supply pump transports the gas to the injection pipe 301 through the connecting pipe 302, and then sprays it out through the outlet hole 303. , the gas ejected from the air outlet 303 contacts the sewage to achieve sewage mixing treatment; at the same time, the first motor 202 drives the stirring plate 204 to move back and forth to stir the sewage and the reagent. At the same time, the size of the air outlet 303 can be adjusted by continuously blocking the air outlet 303 by the stirring plate 204. When the air outlet 303 is blocked, the air outlet 303 becomes smaller. When the air outlet 303 becomes smaller, the injection distance of the gas will increase, and the injection distance is automatically adjusted, thereby improving the sewage treatment effect. When in use, the sewage contacts the auxiliary plate 401. At this time, the sewage can be filtered under the action of the second through hole 402. At the same time When the stirring plate 204 moves left and right to mix the sewage, it can squeeze the protrusion 403, and at this time the auxiliary plate 401 moves up and down. When the auxiliary plate 401 moves up and down, the sewage in the reaction box 1 can be mixed again, and the contact effect between the sewage and the reagent and the decomposition gas in the reaction box 1 can be improved, thereby improving the sewage treatment effect. At the same time, in the process of the stirring plate 204 pushing the protrusion 403 to move upward, the second through hole 402 contacts the blocking block 502. At this time, the right half of the second through hole 402 is blocked. When the auxiliary plate 401 continues to move upward, the downward jet velocity at the second through hole 402 will increase. , at this time, the contact effect between the sewage in the reaction box 1 and the decomposition agent and the decomposition gas can be improved; when discharging, when it is necessary to discharge sewage, first rotate the discharge pipe 702, at this time the discharge pipe 702 moves to the left, and the sewage can enter the discharge pipe 702 through the discharge hole 704, and then open the valve 703. After the discharge is completed, the valve 703 needs to be closed. At this time, if the valve 703 is damaged and cannot be closed, directly rotate the discharge pipe 702 in the opposite direction, and the discharge pipe 702 moves to the left. At this time, the discharge hole 704 is hidden inside the sleeve 701, and the block 705 contacts the left end face of the sleeve 701 to complete the sealing of the discharge pipe 702.
