Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a PDS / PMS advanced oxidation sewage treatment device. Background Art

[0002] With the acceleration of industrialization and urbanization, water pollution is becoming increasingly serious, especially the treatment of difficult-to-degrade organic pollutants has become a major challenge in the field of environmental protection. In the prior art, photocatalytic technology has attracted widespread attention due to its green and efficient characteristics, but there is a problem of low treatment efficiency when used alone. Permonosulfate (PMS) and peroxydisulfate (PDS) are strong oxidants that can generate a variety of active free radicals under photocatalytic conditions and significantly enhance the oxidative degradation ability. However, how to effectively integrate the PMS and PDS photocatalytic processes and optimize the treatment efficiency is still a technical problem that needs to be solved urgently.

[0003] By spraying sewage containing persulfate into atomized form onto a honeycomb catalyst with a large specific surface area, a thin layer of water film is formed on the honeycomb catalyst. Under the continuous irradiation of the ultraviolet lamp in the upper chamber, oxygen-containing species such as sulfate radicals, hydroxyl radicals, superoxide radicals and singlet oxygen further react with organic molecules in the sewage on the surface of the honeycomb catalyst, thereby deeply degrading the organic matter in the sewage. In this process, the large specific surface area of ​​the honeycomb catalyst improves the contact efficiency between oxygen-containing species such as sulfate radicals, hydroxyl radicals, superoxide radicals and singlet oxygen and organic molecules, accelerating the degradation reaction. However, due to the presence of more impurities in sewage, the nozzle is prone to frequent blockage during the process of atomizing and spraying sewage using a conventional nozzle, thereby reducing the sewage treatment efficiency.

[0041] The water pump 9 pumps the water in the lower chamber to the spray assembly, and the spray assembly sprays the sewage onto the honeycomb catalyst layer 7. By atomizing and spraying the sewage containing persulfate onto the honeycomb catalyst layer 7 with a large specific surface area, the sewage forms a thin layer of water film on the honeycomb catalyst layer 7. Under the continuous irradiation of the ultraviolet lamp 5 in the upper chamber, oxygen-containing species such as sulfate radicals, hydroxyl radicals, superoxide radicals and singlet oxygen further react with organic molecules in the sewage on the surface of the honeycomb catalyst layer 7, thereby deeply degrading the organic matter in the sewage. In this process, the large specific surface area of ​​the honeycomb catalyst layer 7 increases the contact efficiency of oxygen-containing species such as sulfate radicals, hydroxyl radicals, superoxide radicals and singlet oxygen with organic molecules, and accelerates the degradation reaction. The sewage that has been secondarily treated in the secondary treatment chamber passes through the honeycomb catalyst layer 7 and is discharged to the outside of the box 1 through the drain port 3.

Specifically, a blind hole is provided at the lower portion of the slide bar 37, the upper portion of the first slide shaft 39 is slidably arranged in the blind hole, a second spring 38 is arranged in the blind hole, the upper end of the second spring 38 is fixedly connected to the slide bar 37, and the lower end of the second spring 38 is fixedly connected to the upper end of the first slide shaft 39.

[0062] After the water pump 9 is started, the sewage in the lower chamber flows through the corrugated water pipe 10, the upper water pipe 17 and the connecting pipe 20, and then flows through the inlet hole 211, the connecting plate 261 and the inlet pipe 26 into the inner core 25. Since a one-way valve 28 is provided in the slot hole 27, the sewage entering the inner core 25 will not be discharged into the housing 21 through the slot hole 27. After being discharged from the lower end of the inner core 25, the sewage is atomized when it flows through the spray hole 45.

[0063] When impurities in the sewage block the spray hole 45, the sewage pressure in the inner core 25 increases, and the sewage in the inner core 25 acts on the vertical shaft 47 in the vertical hole 46, and the inner core 25, the outer sleeve 30 and the atomizing cover move downward. In the initial stage of the downward movement of the inner core 25, the outer sleeve 30 and the atomizing cover, the atomizing caps 33 are slidably connected to the first sliding shaft 39, so that the multiple atomizing caps 33 will not be dispersed.

[0064] When the outer cover 30 moves downward, the slide groove 32 on the outer cover 30 moves downward with the outer cover 30, and the roller 44 moves in the lower inclined portion of the slide groove 32 and gradually approaches the middle position of the slide groove 32. When the roller 44 gradually approaches the middle position of the slide groove 32, the roller 44, the connecting block 43 and the second slide shaft 42 approach the slide rod 37 on one side thereof, and the third spring 41 is compressed.

[0065] During the downward movement of the inner core 25, the first rack 53 causes the first gear 51 to idle, thereby maintaining the connection between the connecting disk 261 and the inlet hole 211 in the initial stage of the downward movement of the inner core 25, thereby preventing sewage from entering the shell 21 through the inlet hole 211 before the roller 44 passes the middle position of the slide groove 32 during the downward movement of the inner core 25.

[0066] Before the roller 44 passes the middle position of the chute 32, the connecting plate 261 remains connected to the inlet hole 211, and sewage does not enter the shell 21, thereby ensuring the pressure of the sewage inside the inner core 25, ensuring that the inner core 25 can continue to descend and allow the roller 44 to pass the middle position of the chute 32.

[0067] When the roller 44 passes the middle position of the slide slot 32, the atomizing cap 33 is separated from the first slide shaft 39. Afterwards, under the elastic force of the third spring 41, the second slide shaft 42 drives the connecting block 43 and the roller 44 to quickly move away from the slide rod 37 on one side thereof.

[0068] In the process of the second sliding shaft 42 driving the connecting block 43 and the roller 44 to quickly move away from the sliding rod 37 on one side thereof, under the elastic force of the third spring 41 and the guiding effect of the inclined portion of the slide groove 32 on the roller 44, the inner core 25, the outer sleeve 30 and the atomizing hood quickly descend. In the process of the inner core 25, the outer sleeve 30 and the atomizing hood quickly descending, when the lower guide surface 352 on the push rod 35 contacts the connecting block 43, under the guiding effect of the lower guide surface 352, the atomizing cap 33 moves toward the outer side of the inner core 25, and multiple atomizing caps 33 are dispersed. After the multiple atomizing caps 33 are dispersed, the impurities blocking the spray hole 45 fall out. After the multiple atomizing caps 33 are dispersed, part of the sewage discharged at the lower end of the inner core 25 can further impact the impurities blocking the spray hole 45.

[0069] When the roller 44 passes the middle position of the chute 32 and the inner core 25 moves downward, the second gear 52 meshes with the second rack 50, and the second rack 50 rotates the connecting plate 261 and the inlet pipe 26 through the second gear 52 and the one-way bearing therein. During the rotation of the connecting plate 261 and the inlet pipe 26, the connecting plate 261 is misaligned with the inlet hole 211, and part of the sewage begins to enter the housing 21 through the inlet hole 211. At this time, the slot 27 moves to the bottom of the housing 21.

[0070] Under the elastic force of the third spring 41 and the guiding effect of the inclined portion of the slide groove 32 on the roller 44, after the inner core 25 moves to the lower dead point, the pull rope 24 is tightened, and the second rack 50 rotates the connecting plate 261 and the inlet pipe 26 by 180 degrees through the second gear 52 and the one-way bearing therein. When the connecting plate 261 is completely misaligned with the inlet hole 211, the sewage will only enter the housing 21.

[0071] As the sewage in the housing 21 increases, under the pressure of the sewage in the housing 21, the sewage in the housing 21 squeezes the piston 23 upward, the first spring 22 is compressed, and the inner core 25, the outer cover 30 and the plurality of atomizing caps 33 are pulled upward by the pull rope 24 during the upward movement of the piston 23. During the upward movement of the inner core 25, the second rack 50 drives the second gear 52 to idle, thereby maintaining the distance between the connecting disk 261 and the inlet hole 211, and preventing the roller 44 from passing the middle position of the slide slot 32 and entering the inlet hole 211 to communicate with the connecting disk 261 during the upward movement of the inner core 25.

[0072] During the upward movement of the inner core 25, before the roller 44 passes the middle position of the chute 32, the connecting plate 261 is not connected to the inlet hole 211, which can ensure the pressure of the sewage in the shell 21, thereby ensuring that the inner core 25 can continue to ascend and allow the roller 44 to move upward and pass the middle position of the chute 32.

[0073] During the upward movement of the inner core 25, when the roller 44 passes the middle position of the slide groove 32, under the elastic force of the third spring 41, the second slide shaft 42 drives the connecting block 43 and the roller 44 to quickly move away from the slide rod 37 on one side thereof. During the process in which the second slide shaft 42 drives the connecting block 43 and the roller 44 to quickly move away from the slide rod 37 on one side thereof, under the elastic force of the third spring 41 and the guiding effect of the lower inclined part of the slide groove 32 on the roller 44, the inner core 25, the outer sleeve 30 and the plurality of atomizing caps 33 quickly move upward. During the rapid upward movement of the inner core 25, the outer sleeve 30 and the plurality of atomizing caps 33, after the upper end of the atomizing cap 33 contacts the lower end of the first slide shaft 39, the atomizing cap 33 can make the first slide shaft 39 move upward and squeeze the second spring 38.

[0074] After the upper guide surface 351 contacts the inclined surface of the wedge block 36, as the inner core 25, the outer sleeve 30 and the multiple atomizing caps 33 continue to move upward, under the guidance of the upper guide surface 351 and the inclined surface of the wedge block 36, the multiple atomizing caps 33 move toward the inner core 25. When the multiple atomizing caps 33 are surrounded to form an atomizing cover, the first sliding shaft 39 passes through the through hole at the upper end of the atomizing cap 33 on one side. At this time, the atomizing cap 33 is restored, and the multiple atomizing caps 33 are surrounded again to form an atomizing cover.

[0075] When the roller 44 passes the middle position of the chute 32 and the inner core 25 moves upward, the first gear 51 meshes with the first rack 53, and the first rack 53 rotates the connecting plate 261 and the inlet pipe 26 through the first gear 51 and the one-way bearing therein. During the rotation of the connecting plate 261 and the inlet pipe 26, after the connecting plate 261 is connected with the inlet hole 211, the sewage begins to enter the inner core 25 through the connecting plate 261. When the inner core 25 reaches the top dead center, the first rack 53 rotates the connecting plate 261 and the inlet pipe 26 back to normal through the first gear 51 and the one-way bearing therein. At this time, the slot 27 is located in the housing 21, and the sewage flowing through the inlet hole 211 only enters the inner core 25, and the sewage is discharged from the lower end of the inner core 25 and sprayed out through the spray hole 45 in atomization.

[0076] After the slot 27 is located in the shell 21, the piston 23 moves downward under the elastic force of the first spring 22. During the process of the piston 23 moving downward, the sewage in the shell 21 enters the inner core 25 through the slot 27 and the one-way valve 28 therein.

[0077] Embodiment 2: Based on Embodiment 1, Figure 2 , Figure 3 , Figure 4 , Figure 7 and Fig. 9 As shown, a lower annular cavity 55 is formed between the inner core 25 and the outer sleeve 30, and a spiral blade 29 is arranged in the lower annular cavity 55, and the spiral blade 29 is fixed on the outer side of the inner core 25. The spiral blade 29 makes the lower annular cavity 55 form a spiral channel, and an air pipe 18 is arranged on one side of the connecting plate 15. The air pipe 18 is fixedly connected to the fixing block 16, and the air pipe 18 is connected to the upper end of the spiral channel through a soft branch pipe 19. An air pump 8 is installed in the installation cavity, and the inlet end of the air pump 8 is connected to the outside of the box body 1, and the outlet end of the air pump 8 is connected to the air pipe 18 through a soft connecting pipe.

[0078] When the sewage is sprayed out from the spray hole 45 in atomized form, the air pump 8 is started. The air pump 8 allows the compressed air to enter the spiral channel through the soft connecting pipe, the air pipe 18 and the soft branch pipe 19. The compressed air spirals downward in the spiral channel. The compressed air acts on the sewage in the spray hole 45 to increase the pressure of the sewage discharged from the spray hole 45, thereby improving the atomization effect of the sewage.

[0079] After the multiple atomizing caps 33 are dispersed, the compressed air spiraling downward can blow away the impurities at the lower ends of the atomizing caps 33, thereby improving the effect of removing the impurities.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
