Technical Field

[0001] This utility model relates to the field of wastewater disinfection technology, specifically to a high-efficiency ultraviolet irradiation device for wastewater disinfection. Background Technology

[0002] Wastewater disinfection is a water treatment process that kills harmful pathogenic microorganisms in domestic sewage and certain industrial wastewater treatment systems. In wastewater disinfection, the efficient use of ultraviolet (UV) radiation mainly relies on the damaging effects of specific wavelengths of UV light on the DNA or RNA of microorganisms.

[0003] For example, the utility model application with application number 202020528841.0 discloses a domestic sewage treatment device that can be disinfected. The structure similar to the above application still has the following shortcomings: it disinfects the sewage by irradiating the sewage with light emitted by an ultraviolet lamp. However, the water flow path of the irradiation method is relatively short, which is not convenient for the sewage to be fully irradiated and sterilized. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency ultraviolet irradiation device for wastewater disinfection, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency ultraviolet irradiation device for wastewater disinfection, comprising a first water tank, a guide plate, and an ultraviolet irradiation component. A second water tank is disposed below the first water tank, a third water tank is disposed below the second water tank, and a fourth water tank is disposed below the third water tank. Guide plates are fixed inside the first, second, third, and fourth water tanks, and flow channels are provided between the guide plates. An ultraviolet irradiation component is installed on the upper inside of the first, second, third, and fourth water tanks. The ultraviolet irradiation component includes a first mounting base, a second mounting base, and an ultraviolet lamp. A second mounting base is disposed outside the first mounting base, and an ultraviolet lamp is installed below the first and second mounting bases.

[0006] Furthermore, the first, second, third, and fourth water tanks are at the same height, and the first and fourth water tanks are respectively provided with an inlet pipe and an outlet pipe on one side.

[0007] Furthermore, the inlet pipe is connected to the first water tank, and the outlet pipe is connected to the fourth water tank.

[0008] Furthermore, the flow channels between the guide plates have an approximately spiral structure, and the sidewalls of the guide plates are fixed with baffles.

[0009] Furthermore, the first mounting base is fixed to the upper inner ring of the first, second, third, and fourth water tanks, and the second mounting base is fixed to the upper outer ring of the first, second, third, and fourth water tanks.

[0010] Furthermore, both the first and second mounting bases are ring-shaped structures, and the ultraviolet lamps on the lower side of the first and second mounting bases are arranged in an array.

[0011] Furthermore, a first drain outlet is provided on the lower side of the middle part of the first water tank, and a second drain outlet is provided on the lower side of the outermost ring of the second water tank.

[0012] Furthermore, a third drain outlet is provided on the lower middle side of the third water tank, and the first drain outlet, the second drain outlet, and the third water tank are all circular openings.

[0013] This utility model provides a high-efficiency ultraviolet irradiation device for wastewater disinfection, which has the following features:

[0014] Beneficial effects:

[0015] This utility model is equipped with a flow channel, an inlet pipe and an outlet pipe for easy water inflow and outflow. The flow channel between the guide plates has an approximately spiral structure, allowing the sewage to flow in a spiral shape. The baffle plate can play a role in turbulence, thereby slowing down the water flow speed. Through the first drain, the sewage in the first water tank can flow into the second water tank under the action of gravity.

[0016] This utility model is equipped with an ultraviolet irradiation component. The first mounting base and the second mounting base, which are in a ring shape, facilitate wiring. The ultraviolet lamps arranged in an array on the lower side of the two bases can irradiate the sewage flowing in the inner and outer rings of the first, second, third, and fourth water tanks. Since the sewage can flow in a spiral shape inside the first, second, third, and fourth water tanks, its flow path is extended, which facilitates the ultraviolet lamps to fully irradiate and sterilize it.

[0022] like Figures 1-2 As shown, a high-efficiency ultraviolet irradiation device for wastewater disinfection includes a first water tank 1, a guide plate 7, and an ultraviolet irradiation assembly 10. A second water tank 2 is disposed below the first water tank 1, a third water tank 3 is disposed below the second water tank 2, and a fourth water tank 4 is disposed below the third water tank 3. Guide plates 7 are fixed inside the first water tank 1, second water tank 2, third water tank 3, and fourth water tank 4, and flow channels 9 are provided between the guide plates 7. The flow channels 9 between the guide plates 7 have an approximately spiral structure, and the side walls of the guide plates 7 are fixed with baffles 8. The first water tank 1, the second water tank 2, the third water tank 3, and the fourth water tank 4 are at the same height, and the first water tank 1 and the fourth water tank 4 are respectively provided with an inlet pipe 5 and an outlet pipe 6 on one side. The inlet pipe 5 is connected to the first water tank 1, and the outlet pipe 6 is connected to the fourth water tank 4. The first water tank 1 has a first drain outlet 11 on the lower side of the middle part, and the second water tank 1 has a drain outlet 11 on the lower side of the middle part. A second drain outlet 12 is provided on the lower side of the outermost ring of water tank 2, and a third drain outlet 13 is provided on the lower side of the middle of the third water tank 3. The first drain outlet 11, the second drain outlet 12, and the third water tank 3 are all circular openings. The filtered sewage is easily sent into the interior of the first water tank 1 through the liquid inlet pipe 5. The flow channel 9 between the guide plates 7 has an approximately spiral structure, which allows the sewage to flow in a spiral shape. The baffle plate 8 can play a role in turbulence and slow down the water flow speed. The sewage in the first water tank 1 can flow into the interior of the second water tank 2 under the action of gravity through the first drain outlet 11. Similarly, the sewage in the second water tank 2 can flow into the interior of the third water tank 3 under the action of gravity through the second drain outlet 12. The sewage in the third water tank 3 can flow into the interior of the fourth water tank 4 under the action of gravity through the third drain outlet 13. The sewage flows in sequence, which can be used in conjunction with the four sets of ultraviolet irradiation components 10 to carry out thorough sterilization and disinfection.

[0023] like Figure 1 and Figure 3 As shown, an ultraviolet irradiation assembly 10 is installed on the upper side of the interior of the first water tank 1, the second water tank 2, the third water tank 3, and the fourth water tank 4. The ultraviolet irradiation assembly 10 includes a first mounting base 1001, a second mounting base 1002, and an ultraviolet lamp 1003. The second mounting base 1002 is provided on the outer side of the first mounting base 1001, and the ultraviolet lamp 1003 is installed on the lower side of the first mounting base 1001 and the second mounting base 1002. The first mounting base 1001 is fixed to the upper side of the inner ring of the first water tank 1, the second water tank 2, the third water tank 3, and the fourth water tank 4, and the second mounting base 1002 is fixed to the upper side of the outer ring of the first water tank 1, the second water tank 2, the third water tank 3, and the fourth water tank 4. Both the first mounting base 1001 and the second mounting base 1002 are ring-shaped structures, and the ultraviolet lamps 1003 on the lower side of the first mounting base 1001 and the second mounting base 1002 are arranged in an array. The ring-shaped structure of the first mounting base 1001 and the second mounting base 1002 facilitates wiring. The ultraviolet lamps 1003 arranged in an array on the lower side of both can irradiate the sewage flowing in the inner and outer rings of the first water tank 1, the second water tank 2, the third water tank 3, and the fourth water tank 4 respectively. Since the sewage can flow in a spiral shape inside the first water tank 1, the second water tank 2, the third water tank 3, and the fourth water tank 4, its flow path is extended, which facilitates the ultraviolet lamps 1003 to fully irradiate and sterilize it.

[0024] In summary, as Figures 1-3As shown, this high-efficiency ultraviolet irradiation device for wastewater disinfection, in use, firstly sends filtered wastewater into the first water tank 1 through the inlet pipe 5. At this time, the flow channel 9 between the guide plates 7 has an approximately spiral structure, allowing the wastewater to flow in a spiral shape. At the same time, the baffle plate 8 can play a role in turbulence, slowing down the water flow speed. During this process, the second mounting base 1002, which has a ring-shaped structure, facilitates wiring. The ultraviolet lamps 1003 arranged in an array on the lower side of both can irradiate the wastewater flowing in the inner and outer rings of the first water tank 1, the second water tank 2, the third water tank 3, and the fourth water tank 4, respectively. Then, the wastewater flows through the first drain outlet 11 into the first water tank. The sewage inside the first water tank 1 can flow into the second water tank 2 under the action of gravity. Similarly, the second drain outlet 12 allows the sewage inside the second water tank 2 to flow into the third water tank 3 under the action of gravity. The third drain outlet 13 allows the sewage inside the third water tank 3 to flow into the fourth water tank 4 under the action of gravity. Since the sewage can flow in a spiral shape inside the first water tank 1, the second water tank 2, the third water tank 3, and the fourth water tank 4, its flow path can be extended, allowing the ultraviolet lamp 1003 to fully irradiate and sterilize it. Finally, the irradiated and disinfected sewage is discharged through the outlet pipe 6. This completes the use process of the ultraviolet high-efficiency irradiation equipment for sewage disinfection.
