Abstract
Description
Technical Field
[0001] This utility model relates to the field of UV photodeodorization technology, and in particular to a UV photodeodorization device for efficiently treating waste gas. Background Technology
[0002] In many areas of industrial production and daily life, such as chemical, pharmaceutical, sewage treatment plants, sewage pumping stations, waste disposal, and spraying industries, large amounts of waste gas containing various pollutants and odors are generated. If these waste gases are directly released into the atmosphere, they will not only cause serious environmental pollution and harm the ecological balance, but also pose a significant threat to human health, potentially causing respiratory diseases and allergic reactions. Currently, various technologies and devices exist for waste gas treatment. Among them, UV photocatalysis deodorization technology has been widely used due to its advantages of high efficiency, no secondary pollution, and ease of operation. When gas enters the UV photolysis zone, the photocatalyst, under light irradiation, produces a photocatalytic reaction similar to photosynthesis, generating highly oxidizing free hydroxyl radicals and reactive oxygen species. This has a strong photo-oxidation function, capable of oxidizing and decomposing various organic compounds and some inorganic substances, destroying bacterial cell membranes and solidifying viral proteins, killing bacteria and decomposing organic pollutants into harmless water (H2O) and carbon dioxide (CO2). It possesses extremely strong bactericidal, deodorizing, mildew-proof, anti-fouling, self-cleaning, and air-purifying functions.
[0003] Conventional UV photodeodorization equipment simply inserts the UV lamps inside the device without any air distribution. The odorous gas is only momentarily passed through the equipment and cannot remain for an extended period. Therefore, to ensure sufficient residence time for the odorous gas and achieve the desired removal effect, multiple rows and multiple lamps must be installed. However, too many lamps increase the overall size of the equipment, increase the floor space, and raise investment and maintenance costs. Therefore, to address these issues, this application proposes a highly efficient UV photodeodorization device for treating waste gas. Utility Model Content
[0004] The main purpose of this invention is to provide a UV photodeodorization device for efficiently treating waste gas, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A high-efficiency UV photodeodorization device for treating waste gas includes an outer casing. Two mounting brackets are symmetrically fixedly installed at the front and back of the outer casing. Several UV photodeodorization components are stacked on the mounting brackets, with adjacent UV photodeodorization components tightly fitted together. Each UV photodeodorization component consists of a transparent cloth duct, a UV lamp, and a spiral air guide plate. The UV lamp is horizontally fixedly installed inside the transparent cloth duct. Two spiral air guide plates are symmetrically fixedly installed on the inner wall of the transparent cloth duct and simultaneously fitted onto the outer wall of the UV lamp. The outer wall of the UV lamp is tightly fitted to the inner side of the spiral air guide plate. A transparent arc-shaped air guide plate is fixedly installed in front of the front mounting bracket inside the outer casing.
[0006] Preferably, the front end of the outer casing is provided with an air inlet, and the rear end of the outer casing is provided with an air outlet.
[0007] Preferably, a filter screen is fixedly installed on the front side of the inner shell, and two titanium dioxide screens are symmetrically fixedly installed on the rear side of the inner shell.
[0008] Preferably, the mounting brackets are located between the titanium dioxide meshes. The two mounting brackets consist of supporting vertical rods, supporting horizontal rods, limiting rods, and mounting connecting plates. There are two supporting vertical rods arranged symmetrically in the horizontal direction. There are several supporting horizontal rods that are symmetrically fixedly installed at one end of the supporting vertical rods. There are several limiting rods that are fixedly installed at one end of the supporting horizontal rods. There are two mounting connecting plates that are respectively fixedly installed at the lower part of one end of the two supporting vertical rods. The mounting connecting plates are also fixedly installed on the bottom wall of the outer casing.
[0009] Preferably, the transparent cloth duct of the UV light deodorization component has two symmetrical air inlets, and an air outlet is provided on the transparent cloth duct between the two air inlets. The air inlets face forward and the air outlet faces backward.
[0010] Preferably, the transparent arc-shaped air guide plate is located between the titanium dioxide mesh on the front side and the mounting bracket on the front side, and the transparent arc-shaped air guide plate is also located between the symmetrically arranged air inlets.
[0011] Compared with the prior art, the present invention has the following beneficial effects: By installing a UV photocatalytic deodorization assembly consisting of a transparent cloth duct, UV lamps, and a spiral guide plate, the spiral guide plate and transparent cloth duct guide the exhaust gas along a spiral path, extending the residence time of the exhaust gas within the transparent cloth duct. This ensures sufficient contact between the exhaust gas and the UV lamps, enhancing the photolysis reaction effect and improving deodorization efficiency. Simultaneously, it reduces the number of lamps used, shrinking the equipment size and lowering investment and operating / maintenance costs. Furthermore, by installing a mounting bracket and stacking the UV photocatalytic deodorization assembly on it, the assembly and disassembly of the UV photocatalytic deodorization assembly can be easily performed, improving the convenience and efficiency of equipment maintenance. By setting up transparent arc-shaped air guide plates, the exhaust gas entering the device can be streamlined. Utilizing the guiding characteristics of the arc structure, the exhaust gas is precisely directed to the air inlet of the transparent cloth duct, reducing turbulence loss and energy dispersion during the flow of the exhaust gas. This allows the exhaust gas to enter the transparent cloth duct with a more uniform flow rate and a more concentrated flow direction, avoiding insufficient local air intake or airflow short-circuiting caused by airflow turbulence. This ensures that the air inlet of each transparent cloth duct can efficiently receive exhaust gas, laying the foundation for the uniformity and sufficiency of the subsequent UV photolysis reaction, thereby improving the exhaust gas treatment efficiency and stability of the entire device.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0015] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a high-efficiency UV photodeodorization device for treating waste gas includes an outer casing 1. Two mounting brackets 2 are symmetrically fixedly installed inside the outer casing 1. Several UV photodeodorization components 3 are stacked on the mounting brackets 2, with adjacent UV photodeodorization components 3 tightly fitted together. Each UV photodeodorization component 3 consists of a transparent cloth duct 13, a UV lamp 14, and a spiral guide plate 15. The UV lamp 14 is horizontally fixedly installed inside the transparent cloth duct 13. Two spiral guide plates 15 are symmetrically fixedly installed. The spiral guide plate 15 is mounted on the inner wall of the transparent cloth duct 13 and simultaneously fitted onto the outer wall of the UV lamp tube 14. The outer wall of the UV lamp tube 14 is tightly fitted to the inner side of the spiral guide plate 15. A transparent arc-shaped guide plate 4 is fixedly installed inside the outer casing 1 and in front of the mounting bracket 2 on the front side. By setting up the UV light deodorization assembly 3, which consists of the transparent cloth duct 13, the UV lamp tube 14, and the spiral guide plate 15, the spiral guide plate 15 and the transparent cloth duct 13 can guide the exhaust gas to flow along the spiral path, prolonging the exhaust gas's flow in the transparent cloth. The residence time within the duct 13 allows for sufficient contact between the exhaust gas and the UV lamps 14, enhancing the photolysis reaction effect and improving deodorization efficiency. Simultaneously, it reduces the number of lamps used, shrinking the equipment size and lowering investment and operation / maintenance costs. By setting up the mounting bracket 2 and stacking the UV photolysis deodorization components 3 on it, the disassembly and maintenance of the UV photolysis deodorization components 3 can be easily facilitated, improving the convenience and efficiency of equipment maintenance. The transparent arc-shaped air guide plate 4 streamlines the exhaust gas entering the device, using the guiding characteristics of the arc structure to precisely direct the exhaust gas to the air inlet 16 of the transparent cloth duct 13. This reduces turbulence loss and energy dispersion during the flow of the exhaust gas, allowing it to enter the transparent cloth duct 13 with a more uniform flow rate and a more concentrated flow direction. This avoids insufficient local air intake or airflow short-circuiting caused by airflow turbulence, ensuring that each air inlet 16 of the transparent cloth duct 13 can efficiently receive exhaust gas, laying the foundation for the uniformity and sufficiency of the subsequent UV photolysis reaction, thereby improving the overall exhaust gas treatment efficiency and stability of the device.
[0016] Specifically, the front end of the outer casing 1 is provided with an air inlet 5, and the rear end of the outer casing 1 is provided with an air outlet 6. A filter screen 7 is fixedly installed on the front side of the interior of the outer casing 1, and two titanium dioxide screens 8 are symmetrically fixedly installed on the rear side of the interior of the outer casing 1. The mounting brackets 2 are located between the titanium dioxide screens 8. The two mounting brackets 2 are composed of supporting vertical rods 9, supporting horizontal rods 10, limiting rods 11, and mounting connecting plates 12. There are two supporting vertical rods 9, which are arranged horizontally symmetrically. There are several supporting horizontal rods 10, which are symmetrically fixedly installed at one end of the supporting vertical rods 9. There are several limiting rods 11, which are fixedly installed at one end of the supporting horizontal rods 10. There are two mounting connecting plates 12, which are respectively fixedly installed at the lower part of one end of the two supporting vertical rods 9. The mounting connecting plates 12 are also fixedly installed on the bottom wall of the outer casing 1. Two air inlets 16 are symmetrically opened on the transparent cloth air duct 13 on the UV light deodorization component 3. An air outlet 17 is opened on the transparent cloth air duct 13 between the two air inlets 16. The air inlets 16 face forward, and the air outlet 17 faces forward. Facing rearward, the transparent arc-shaped air guide plate 4 is located between the titanium dioxide mesh 8 and the mounting bracket 2 on the front side. The transparent arc-shaped air guide plate 4 is also located between the symmetrically arranged air inlets 16. The filter screen 7 mainly removes larger solid particles, dust and other impurities in the exhaust gas through physical interception, playing a preliminary filtration and purification role. The transparent cloth air duct 13 and the transparent arc-shaped air guide plate 4 are both made of materials with good light transmittance. The ultraviolet rays emitted by the UV lamp tube 14 pass through the transparent cloth air duct 13 and the transparent arc-shaped air guide plate 4 and irradiate the titanium dioxide mesh 8. Under the irradiation of the ultraviolet rays emitted by the UV lamp tube 14, the titanium dioxide mesh 8 produces a photocatalytic reaction, generating free hydroxyl radicals and active oxygen with strong oxidizing ability, which can oxidize and decompose organic pollutants and some inorganic substances, further purifying the exhaust gas. The ultraviolet rays emitted by the UV lamp tube 14 can destroy the cell membrane of bacteria in the exhaust gas, solidify viral proteins, and at the same time promote the photolysis reaction of organic pollutants in the exhaust gas, decomposing them into harmless substances such as water and carbon dioxide, achieving the purpose of deodorization and purification.
[0017] In use, exhaust gas enters through the air inlet 5 at the front of the outer casing 1, first passing through the filter screen 7 on the front side of the inner casing 1 and the titanium dioxide screen 8 on the front side. Then, guided by the transparent arc-shaped air guide plate 4, it is precisely directed to the symmetrically opened forward-facing air inlet 16 on the transparent cloth air duct 13 and enters the transparent cloth air duct 13. Inside the transparent cloth air duct 13, the exhaust gas flows along a spiral path under the action of two spiral air guide plates 15 symmetrically fixed on the inner wall of the transparent cloth air duct 13 and the outer wall of the UV lamp tube 14, prolonging its residence time. The UV light deodorization component 3 undergoes a photolysis reaction. The gas produced after the reaction is discharged from the air outlet 17 located between the two air inlets 16 and facing the rear on the transparent cloth air duct 13. It is then further processed by the titanium dioxide mesh 8 on the rear side of the outer casing 1 and finally discharged from the air outlet 6 at the rear end of the outer casing 1. When the UV light deodorization component 3 needs maintenance, the inspection door on the outer casing 1 is opened, and the UV light deodorization component 3 can be directly pulled out from the limit rod 11 on the mounting bracket 2, and then the UV light deodorization component 3 can be maintained.
[0018] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
