Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to an advanced oxidation device. Background Art

[0002] After sewage is pretreated and biochemically treated, a certain concentration of organic matter still remains in the effluent. It is this type of organic matter that affects the water quality. This type of pollutant is mainly difficult to degrade organic matter, which is highly toxic and has poor biodegradability. Conventional treatment processes are difficult to achieve satisfactory results and require other deep treatment methods to remove. Ozone oxidation technology has a place in the field of deep treatment due to its strong oxidation ability. The existing ones generally have poor oxidation effect, low oxidation efficiency, poor degradation effect on organic matter in wastewater, and high operating costs due to low utilization of effective oxidants.

[0003] To this end, an advanced oxidation device is proposed. Utility Model Content

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The utility model transports wastewater to the inside of the box through a wastewater inlet pipe, and then connects the ozone pipe with the ozone inlet pipe. At this time, ozone enters the inside of the box through the ozone inlet pipe, and ozone and wastewater pass through two cutting plates in sequence. When ozone passes through the cutting plates, the water holes on the top of the cutting plates can effectively cut the ozone gas, so that the single body with a small surface area of ​​the ozone gas becomes a multi-body with a large surface area, thereby increasing the contact area between the wastewater and the ozone, thereby enhancing the effective utilization rate of the ozone;

[0019] Ozone from bottom to top will enter the collection box through the ozone outlet pipe and the first connecting pipe, and then be transported to the ozone inlet pipe by the pump in the collection box and enter the box again, thereby achieving energy saving and recycling of ozone and reducing operating costs.

[0020] The utility model is provided with a sealing gasket, under the action of which the sealing gasket can improve the sealing performance between the sealing plate and the bottom of the box body, thereby avoiding leakage at the connection between the sealing plate and the bottom of the box body;

[0021] The utility model rotates the rotating shaft in the reverse direction, and the rotating shaft drives the threaded rod to move in the threaded hole. After the fixing plate at one end of the threaded rod is out of contact with the box body, the sealing plate can be disassembled. Therefore, the utility model is convenient for disassembling the sealing plate and avoids cleaning the sludge inside the box body. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Specifically, the utility model transports wastewater to the inside of the box body 1 through the wastewater inlet pipe 4, and then connects the ozone tube to the ozone inlet pipe 6. At this time, ozone enters the inside of the box body 1 through the ozone inlet pipe 6. Ozone and wastewater pass through two cutting plates 13 in sequence. When ozone passes through the cutting plates 13, the water holes 14 on the top of the cutting plates 13 can effectively cut the ozone gas, so that the small surface area of ​​the monomer of the ozone gas is changed into a large surface area of ​​multiple bodies, thereby increasing the contact area between the wastewater and the ozone, thereby enhancing the effective utilization rate of the ozone.

[0032] Ozone from bottom to top will enter the collection box 9 through the ozone outlet pipe 7 and the first connecting pipe 8, and then be transported to the ozone inlet pipe 6 through the pump in the collection box 9 and enter the box body 1 again, thereby achieving energy saving and recycling of ozone and reducing operating costs.

[0035] Specifically, the utility model is provided with a sealing gasket 3, under the action of the sealing gasket 3, the sealing performance between the sealing plate 2 and the bottom of the box body 1 can be improved to avoid leakage at the connection between the sealing plate 2 and the bottom of the box body 1;

[0036] The utility model rotates the rotating shaft 19 in the reverse direction, and the rotating shaft 19 drives the threaded rod 17 to move in the threaded hole 16.

At this time, ozone will enter the inside of the box 1 through the ozone inlet pipe 6. Ozone and wastewater pass through two cutting plates 13 in sequence. When ozone passes through the cutting plates 13, the water holes 14 on the top of the cutting plates 13 can effectively cut the ozone gas, so that the small surface area of ​​the monomer of the ozone gas is changed into a large surface area of ​​multiple bodies, thereby increasing the contact area between the wastewater and the ozone, thereby enhancing the effective utilization rate of the ozone;

[0039] Ozone from bottom to top will enter the inside of the collection box 9 through the ozone outlet pipe 7 and the first connecting pipe 8, and then be transported to the ozone inlet pipe 6 through the pump in the collection box 9 and enter the inside of the box body 1 again, so as to achieve energy saving and recycling of ozone and reduce operating costs;

[0041] Finally, by rotating the rotating shaft 19 in the opposite direction, the rotating shaft 19 drives the threaded rod 17 to move in the threaded hole 16. After the fixing plate 18 at one end of the threaded rod 17 is out of contact with the box body 1, the sealing plate 2 can be disassembled. Therefore, the utility model facilitates the disassembly of the sealing plate 2 and avoids cleaning the sludge inside the box body 1.
