Description

Technical Field

[0001] This utility model relates to the field of ozone dosing technology, and in particular to an ozone dosing device. Background Technology

[0002] Ozone, also known as superoxide, is an allotrope of oxygen. At room temperature, it is a pale blue gas with a distinctive odor. Ozone has extremely strong oxidizing properties and is an ideal green oxidant, widely used in wastewater purification. To facilitate the dissolution of ozone in wastewater, ozone dosing devices are required.

[0003] Existing ozone dosing devices typically include an ozone dosing body and an ozone delivery pipe. The ozone delivery pipe is connected to the ozone dosing body and is used to deliver ozone into the ozone dosing body. The ozone dissolves in the wastewater contained in the ozone dosing body for purification. However, the inner diameter of the ozone delivery pipe is relatively large, resulting in larger ozone bubbles. This leads to a smaller contact area between the ozone per unit volume and the wastewater, resulting in poor dissolution efficiency. Furthermore, Chinese patent (CN219860803U) discloses a novel ozone dosing device for ozone catalytic oxidation process. This device has a rotating rod inside the main body of the dosing device, and four sets of stirring shafts are set at the bottom of the rotating rod. The wastewater is stirred by the stirring shafts. However, the four sets of stirring shafts are located at the bottom of the main body of the dosing device, and the stirring is only carried out by the four sets of stirring shafts, resulting in poor stirring effect.

The second stirring component 3 is installed inside the main body 1 of the dosing device. It includes two sets of vent pipes 31 symmetrically arranged about the rotating shaft 21. Both sets of vent pipes 31 are fixedly connected to the rotating shaft 21 through connecting rods 32. Multiple sets of stirring pipes 33 connected to the outer wall of the vent pipes 31 are fixedly installed. Multiple air outlets 331 are opened on the outer wall of the stirring pipes 33 for adding ozone into the main body 1 of the dosing device and stirring the sewage. The gas supply component 4 is connected to the vent pipe 31 and is used to deliver ozone into the vent pipe 31. The stirring rod 22 and the stirring tube 33 are arranged alternately.

[0018] In this embodiment, the main body 1 of the dosing device is a cylindrical sealed shell. The inlet 11 is connected to the sewage inlet pipe, and the outlet 12 is connected to the drainage pipe. Solenoid valves for controlling the opening and closing of the pipes are installed on both the inlet pipe and the drainage pipe. Sewage flows into the main body 1 of the dosing device from the inlet 11, and after ozone treatment, it is discharged from the outlet 12. The first stirring assembly 2 has multiple sets of stirring rods 22 on the rotating shaft 21. The multiple sets of stirring rods 22 are divided into two columns and are symmetrically arranged. Each column includes multiple sets of stirring rods 22 arranged vertically. The second stirring assembly 3 has multiple sets of stirring tubes 33 on the outer wall of the vent pipe 31. The stirring tubes 33 are divided into four columns and are arranged in a circle. Each column includes multiple sets of stirring tubes 33 arranged vertically.

The outer wall of the vent pipe 31 is provided with multiple sets of through holes. The stirring pipe 33 has an open structure at one end and a sealed structure at the other end. The open end of the stirring pipe 33 is connected to the through hole of the vent pipe 31, so that the ozone flows into the stirring pipe 33 after passing through the vent pipe 31 and is discharged into the main body 1 of the dosing device from the gas outlet 331 on the stirring pipe 33. During operation, the gas supply component 4 delivers ozone to the vent pipe 31. After passing through the vent pipe 31 and the stirring pipe 33, the ozone is discharged from the vent hole 331. Simultaneously, the drive motor 23 is started, driving the rotating shaft 21 and the vent pipe 31 to rotate, which in turn drives multiple sets of stirring rods 22 and multiple sets of stirring pipes 33 to rotate, stirring the sewage in the main body 1 of the dosing device. Compared with the prior art, which only sets four stirring shafts in the main body 1 of the dosing device, this application has a wider range of sewage stirring, and the stirring effect is better under double stirring, which can make the ozone fully dissolve in the sewage. In addition, in this application, the ozone is discharged from the smaller diameter vent hole 331, which can reduce the volume of ozone bubbles, thereby increasing the contact area between the ozone bubbles per unit volume and the sewage, and improving the ozone dissolution effect.

[0019] In a preferred embodiment, such as Figure 3 As shown, the outer circumference of the stirring rod 22 is provided with a serrated structure.

[0020] In this embodiment, multiple sets of rectangular strips are fixedly arranged on the outer wall of the stirring rod 22. During the stirring process, the serrated strips can cut and tear large bubbles into more and smaller bubbles by applying shearing force, thereby increasing the surface area of ​​ozone per unit volume, thus increasing the contact area between ozone and sewage and improving the dissolution rate.

[0021] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, the gas supply assembly 4 includes a first gas supply pipe 41 fixedly installed on the top of the main body 1 of the dosing device. An ozone inlet pipe 44 is fixedly connected to the top of the first gas supply pipe 41, and a second gas supply pipe 42 is rotatably connected to the bottom of the first gas supply pipe 41. The second gas supply pipe 42 is fixedly connected and communicated with two sets of ventilation pipes 31 through a connecting pipe 43.

[0022] Preferably, the top end of the second gas supply pipe 42 is an open structure and the bottom end is a sealed structure, and the top end of the second gas supply pipe 42 is rotatably connected to the bottom end of the first gas supply pipe 41 through a rotary joint 45, and the bottom end of the second gas supply pipe 42 is fixedly connected to the rotating shaft 21.

[0023] In this embodiment, the ozone inlet pipe 44 is fixedly connected to the outlet of the ozone generator, and a pressure pump is also installed on the ozone inlet pipe 44 to allow ozone to enter the first gas delivery pipe 41 under a certain pressure. The first gas delivery pipe 41 and the second gas delivery pipe 42 are connected and communicated through a rotary joint 45. Ozone flows into the second gas delivery pipe 42 through the first gas delivery pipe 41. Two sets of connecting pipes 43 are fixedly connected to the outer wall of the second gas delivery pipe 42. The other end of the connecting pipe 43 is connected to the top of the ventilation pipe 31. Ozone flows into the ventilation pipe 31 through the second gas delivery pipe 42 and the connecting pipes 43, thus realizing the delivery of ozone. The rotary joint 45 can be a commercially available rotary joint.

[0024] In a preferred embodiment, such as Figure 1 As shown, a sliding ring 5 is fixedly sleeved on the inner wall of the main body 1 of the dosing device along its circumference. A circular groove is opened on the inner ring of the sliding ring 5 along its circumference. A slider 311 is fixedly installed on the outer wall of both sets of air pipes 31. The slider 311 is slidably connected to the circular groove.

[0025] In this embodiment, the sewage level inside the main body 1 of the dosing device is located below the sliding ring 5 to prevent dirt in the sewage from getting stuck in the circular chute; When the vent pipe 31 rotates, the slider 311 rotates in the circular groove, and the sliding ring 5 provides auxiliary support for the vent pipe 31, improving the stability of the vent pipe 31 during rotation.

[0026] In a preferred embodiment, such as Figure 2 As shown, a mounting bracket is fixedly installed on the top of the stirring tube 33, and multiple sets of dispersing rods 34 are fixedly installed on the mounting bracket.

[0027] In this embodiment, as the stirring tube 33 rotates, ozone bubbles are discharged from the vent 331 and rise in the wastewater. At the same time, as the stirring tube 33 rotates, it drives the dispersing rod 34 to rotate synchronously. The dispersing rod 34 is a thin rod with multiple branches. When the dispersing rod 34 rotates, it can disperse the ozone bubbles in the wastewater, making the ozone bubbles smaller, thereby increasing the ozone surface area per unit volume and improving the dissolution rate.

[0028] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, a one-way valve 35 is provided at one end of the stirring tube 33 near the vent pipe 31.

[0029] In this embodiment, the one-way valve 35 serves to prevent sewage from flowing back into the vent pipe 31.

[0030] In a preferred embodiment, such as Figure 1 As shown, the top of the main body 1 of the dosing device is also provided with an air outlet 13, which is connected to an external ozone destroyer.

[0031] In this embodiment, the main body 1 of the ozone dosing device is also equipped with a detection probe of an ozone concentration detector, and an electromagnetic valve is installed on the outlet pipe 13. After the ozone is added and reacted for a period of time, the undissolved ozone rises to the top of the main body 1 of the ozone dosing device. The ozone concentration inside the main body 1 of the ozone dosing device is detected by the ozone concentration detector. If the concentration of undissolved ozone is within the measurement range, the electromagnetic valve opens, and the ozone enters the ozone destroyer for elimination, thus preventing the undissolved ozone from being discharged and causing air pollution.

[0032] Working principle: Inlet 11 is connected to the sewage inlet pipe, and outlet 12 is connected to the drainage pipe. Sewage flows into the main body 1 of the dosing device through inlet 11. When the ozone generator is working, ozone flows into the ventilation pipe 31 through ozone inlet pipe 44, first gas supply pipe 41, second gas supply pipe 42 and connecting pipe 43. After passing through the ventilation pipe 31, it flows into the stirring pipe 33 connected to it and flows out from the outlet hole 31. At the same time, the drive motor 23 is started, driving the rotating shaft 21 and the ventilation pipe 31 to rotate, thereby driving multiple sets of stirring rods 22. The multiple sets of stirring tubes 33 rotate to stir the sewage in the main body 1 of the dosing device; this application performs double stirring of the sewage, resulting in better stirring effect and allowing ozone to fully dissolve in the sewage; in this application, ozone is discharged through the small-diameter vent 331, which can reduce the volume of ozone bubbles, and under the action of the serrated structure and the dispersing rod, the ozone bubbles are cut again, reducing the volume of ozone bubbles, thereby increasing the contact area between the ozone bubbles per unit volume and the sewage, and improving the ozone dissolution effect.
