Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment, and in particular to an integrated ultraviolet and ozone sterilization system. Background Technology

[0002] In the field of water treatment equipment, the technology combining ultraviolet (UV) disinfection and ozone disinfection, as an important component of advanced oxidation technology, exhibits excellent sterilization and disinfection effects due to the strong oxidizing hydroxyl radicals generated during the reaction process, and is widely used in water treatment. In existing technologies, such as the UV-ozone combined water treatment device disclosed in Chinese Utility Model Patent No. CN2808883Y, its structure includes a cavity, a filter adsorption layer, a top cover, a sealing structure, a UV lamp, a treated water transition tank, and a support. The lower part of the cavity is equipped with a water inlet pipe and an ozone inlet pipe, and the interior of the cavity contains a filter adsorption layer and a UV lamp.

[0003] However, this type of device has certain limitations: on the one hand, the ozone is injected through a single air inlet, resulting in poor diffusion efficiency of ozone in the water body, making it difficult to fully contact and mix with the water to be treated, thus affecting the full realization of the oxidation and sterilization effect; on the other hand, the configuration of a single ultraviolet lamp group means that it can only adapt to the needs of small-flow sewage treatment. When facing large-flow water treatment scenarios, the treatment efficiency and sterilization effect are difficult to meet the actual application requirements. Utility Model Content

[0004] The purpose of this invention is to provide an integrated ultraviolet and ozone sterilization system. This invention effectively enhances the sterilization effect by integrating a porous ozone diffusion structure with multiple sets of ultraviolet lamps, thus meeting the needs of high-flow-rate wastewater treatment scenarios.

[0005] The technical solution of this utility model is as follows: an integrated ultraviolet and ozone sterilization system, including a cabinet and an electrical cabinet. One end of the cabinet has a water inlet pipe, and the back of the cabinet has a water outlet pipe. Multiple holes at the bottom of the cabinet have air outlet pipes connected to an ozone generating mechanism. The port of the air outlet pipe has an ozone diffuser installed inside the cabinet. The other end of the cabinet is provided with multiple neatly arranged ultraviolet lamp groups. The irradiation end of the ultraviolet lamp groups is located inside the cabinet. The cabinet is provided with a support for supporting the ultraviolet lamp groups.

[0006] In the aforementioned integrated ultraviolet and ozone sterilization system, an exhaust valve is provided on the top of the chamber to reduce the air pressure inside the chamber.

[0007] In the aforementioned integrated ultraviolet and ozone sterilization system, the ozone diffuser includes a column connected to the port of the outlet pipe, a plate at the upper end of the column, an arched cover on the plate, a sealing ring between the arched cover and the plate, and multiple diffusion holes on the arched cover.

[0008] In the aforementioned integrated ultraviolet and ozone sterilization system, one end of the box has a vertical plate with multiple neatly arranged positioning holes on the plate, and the ultraviolet lamp group is inserted into the positioning holes.

[0009] In the aforementioned integrated ultraviolet and ozone sterilization system, the ultraviolet lamp assembly includes a transparent tube sleeve that passes through a positioning hole and a support member. A lamp tube is installed inside the transparent tube sleeve, and one end of the lamp tube is connected to a connector. A rotatable plug cap is provided on the connector cap, and the plug cap is connected to one end of the transparent tube sleeve by threads.

[0010] In the aforementioned integrated ultraviolet and ozone sterilization system, the support component includes a partition disposed inside the box, with first support plates on both sides of the partition and a second support plate on the inner wall of the box; part of the transparent tube sleeve passes through the first support plate, and another part of the transparent tube sleeve passes through the second support plate; the first support plate and the second support plate are staggered.

[0011] In the aforementioned integrated ultraviolet and ozone sterilization system, a cover is provided at one end of the housing and on the side of the ultraviolet lamp group.

[0012] In the aforementioned integrated ultraviolet and ozone sterilization system, the upper end of the electrical cabinet, corresponding to the cover door, is provided with a wiring hole to restrict the ultraviolet lamp assembly circuit.

[0013] Compared with the prior art, the present invention has the following advantages: 1. In this utility model, multiple air outlet pipes with holes are set at the bottom of the box, and an ozone diffuser is set in conjunction with them. The multiple holes allow ozone to be injected from different areas of the water body. The domed cover and diffusion holes of the ozone diffuser further disperse the ozone evenly, which greatly improves the diffusion efficiency of ozone in the water body and significantly enhances the contact and mixing degree between ozone and the water to be treated, effectively improving the oxidation and sterilization effect. Secondly, this utility model adopts multiple neatly arranged ultraviolet lamp groups, which greatly increases the irradiation range and intensity of ultraviolet light, making the distribution of ultraviolet lamp groups more reasonable, enabling more comprehensive irradiation of the water body, improving the treatment efficiency, and adapting to high-flow sewage treatment scenarios.

[0014] 2. The transparent tube sleeve of the ultraviolet lamp group is fixed by the first and second support plates to prevent the lamp group from shaking or shifting during water flow impact or equipment operation, ensuring the stability of the lamp group installation. In addition, the two staggered support plates can slow down the water flow speed, extend the water residence time in the box, fully contact ozone, increase the water irradiation time, and improve the sterilization effect.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0018] Example: An integrated ultraviolet and ozone sterilization system, including a housing 1 and an electrical cabinet 2, as shown in the attached diagram. Figure 1As shown, one end of the tank 1 has an inlet pipe 3, and the back of the tank 1 has an outlet pipe 4. Wastewater enters through the inlet pipe, and the treated water flows out through the outlet pipe. The ozone has extremely strong oxidizing properties, which can efficiently decompose organic pollutants (such as pesticides, dyes, detergents, etc.) and reducing inorganic substances (such as sulfides, nitrites, etc.) in the water, breaking down large molecular pollutants into smaller molecules, improving the biodegradability of wastewater, and achieving rapid inactivation by destroying the cell membranes, proteins, and nucleic acid structures of microorganisms such as bacteria, viruses, and algae. It has high sterilization efficiency and a wide range of action. Ultraviolet light can penetrate the cell membranes of microorganisms, destroy their molecular structure, prevent microbial reproduction, and achieve sterilization and disinfection. It has a significant inactivation effect on bacteria, viruses, protozoa, etc. When combined, the oxidation effect of ozone can remove some pollutants that affect the penetration of ultraviolet light, thus improving the sterilization efficiency of ultraviolet light. Ultraviolet light can decompose any remaining ozone after ozone treatment, while also compensating for the incomplete inactivation of certain microorganisms by ozone, resulting in a synergistic sterilization effect. Multiple holes at the bottom of the housing 1 have exhaust pipes 5 connected to the ozone generator. The exhaust pipes are welded to the holes at the bottom of the housing to ensure good sealing. The ozone generator mainly uses a high-frequency, high-voltage electric field to act on dry oxygen or air, causing oxygen molecules in the gas to be bombarded and decomposed into oxygen atoms. Some oxygen atoms combine with oxygen molecules to form ozone. The port of the exhaust pipe 5 has an ozone diffuser 6 installed inside the housing 1, as shown in the attached diagram. Figure 4 As shown, the ozone diffuser 6 includes a column 10 connected to the port of the outlet pipe 5. The outer side of the column is threaded to the inner wall of the outlet pipe, and a sealing ring is fitted at one end of the thread to reduce gas leakage from the side. The upper end of the column 10 has a disc 11, and a domed cover 12 is provided on the disc 11. A sealing ring 13 is provided between the domed cover 12 and the disc 11. Figure 5 As shown, the domed cover 12 has multiple diffusion holes 14. Ozone gas flows out from the diffusion holes, generating ozone bubbles in the water within the tank and dissolving in the water. At the other end of the tank 1, multiple neatly arranged ultraviolet lamp groups 7 are provided. The irradiation ends of the ultraviolet lamp groups 7 are located inside the tank 1. Support members 8 for supporting the ultraviolet lamp groups 7 are provided inside the tank 1, as shown in the attached diagram. Figure 3 As shown; one end of the box 1 has a vertical plate 15, as attached. Figure 2As shown, the upright plate 15 has multiple neatly arranged positioning holes 16. The ultraviolet lamp group 7 passes through the positioning holes 16. The ultraviolet lamp group is positioned by setting positioning holes on the upright plate. The structure is simple and the positioning is stable. There are 18 ultraviolet lamp groups in total, which are evenly arranged on the upright plate. The top of the box 1 is equipped with an exhaust valve 9 to reduce the air pressure inside the box 1. When the system is running, ozone is injected into the water through the diffuser. Some undissolved ozone will remain in gaseous form. At the same time, water flow and ultraviolet irradiation may cause a small amount of water vapor to evaporate, resulting in an increase in the amount of gas inside the box and a gradual increase in air pressure. The exhaust valve can discharge excess gas in time to avoid pressure shock to the box structure, pipe interface or sealing components caused by excessive air pressure, and prevent the equipment from being damaged by overpressure. For ozone gas that is not soluble in water, an exhaust gas treatment device is installed on the top of the chamber. An exhaust gas collection pipe is installed on the top of the chamber, and the end of the exhaust gas collection pipe is connected to a vertical activated carbon adsorption tower. The tower is filled with columnar ozone-specific activated carbon. Undissolved ozone exhaust gas enters the adsorption tower through the exhaust gas collection pipe. The activated carbon pores adsorb ozone molecules and a catalytic decomposition reaction occurs at the same time. After treatment, the exhaust gas is discharged through the exhaust pipe at the top of the adsorption tower.

[0019] The ultraviolet lamp assembly 7 includes a transparent tube sleeve 17 that passes through the positioning hole 16 and the support member 8, as shown in the attached figure. Figure 7 As shown, an annular groove is formed on the outer wall of the transparent sleeve, and an ozone-resistant and water-resistant fluororubber or nitrile rubber O-ring is embedded in the groove. When the transparent sleeve is inserted into the positioning hole, the O-ring is deformed by the compression between the outer wall of the sleeve and the inner wall of the positioning hole, forming a radial sealing surface, which can effectively block the flow path of liquid and gas. This structure has a reliable sealing effect, and the O-ring is easy to replace, making it suitable for scenarios with long-term contact with ozone and water. A lamp tube 18 is installed inside the transparent sleeve 17. The ultraviolet light emitted by the lamp tube passes through the transparent sleeve to irradiate the water in the tank. One end of the lamp tube 18 is connected to a connector 19, as shown in the attached diagram. Figure 8 As shown, one end of the lamp tube has a needle-type electrode structure, which is inserted into the connector. The outer end of the connector is connected to the power supply via a circuit. A rotatable end cap 20 is concealed on the connector 19. The end cap 20 is connected to one end of the transparent sleeve 17 via a thread. After the lamp tube is placed inside the transparent sleeve, the connector is connected to the lamp tube, and the end cap is rotated to one end of the transparent sleeve to fix the connector. The upper end of the electrical cabinet 2, corresponding to the cover door 24, has a wiring hole 25 to restrict the wiring of the ultraviolet lamp group 7. There are multiple ultraviolet lamp groups, and all the wiring passes through the wiring hole. The wiring holes constrain the wiring to organize each wire in an orderly manner. One end of the cabinet 1, located on the side of the ultraviolet lamp group 7, has a cover door 24. After opening the cover door, the connector, end cap, and other components of the ultraviolet lamp group can be directly accessed, providing a convenient operating channel for lamp replacement, cleaning of the transparent sleeve, or fault diagnosis, without disassembling other structures of the cabinet, greatly improving maintenance efficiency.

[0020] The support member 8 includes a partition 21 disposed inside the housing 1, as shown in the attached figure. Figure 6 As shown, the partition 21 has first support plates 22 on both sides, and a second support plate 23 on the inner wall of the housing 1; part of the transparent tube sleeve 17 passes through the first support plate 22, and another part of the transparent tube sleeve 17 passes through the second support plate 23; the first support plate 22 and the second support plate 23 are staggered. The transparent tube sleeve of the ultraviolet lamp group is fixed by the first and second support plates to prevent the lamp group from shaking or shifting during water flow impact or equipment operation, ensuring the stability of the lamp group installation. In addition, the two staggered support plates can slow down the water flow speed, prolong the water residence time in the housing, fully contact with ozone, increase the water irradiation time, and improve the sterilization effect.

[0021] The working principle of this utility model is as follows: Under the action of the ozone diffuser 6 at the outlet pipe 5, ozone first enters the column 10, then passes through the space between the disk 11 and the dome 12, and finally is evenly dispersed into the water through multiple diffusion holes 14 on the dome 12. Meanwhile, the electrical cabinet 2 supplies power to multiple ultraviolet lamp groups 7 via wiring. The ultraviolet rays emitted by the lamp tubes 18 irradiate the water inside the box 1 through the transparent sleeves 17. The first support plates 22 on both sides of the partition 21 are staggered with the second support plates 23 on the inner wall of the box 1. Part of the transparent sleeves 17 pass through the first support plate 22 and the other part passes through the second support plate 23. This not only provides stable support for the ultraviolet lamp groups 7 and prevents them from shaking under the impact of water flow, but also slows down the water flow speed, prolongs the residence time of sewage in the box 1, and allows the sewage to fully react with ozone and receive more comprehensive ultraviolet irradiation, thus improving the sterilization effect. When the system is running, the evaporation of some undissolved ozone gas and water flow, as well as the trace water vapor generated by ultraviolet irradiation, will cause the air pressure inside the box 1 to rise. The exhaust valve 9 at the top can release excess gas in time to avoid damage to the equipment due to excessive air pressure. The treated sewage is discharged through the outlet pipe 4 on the back side of the box 1.
