Technical Field
[0001] This utility model relates to the field of photocatalysis technology, and more specifically, to a high-efficiency photocatalytic processing device with optimized ultraviolet light distribution. Background Technology
[0002] The ultraviolet high-efficiency photocatalytic treatment device is a device that uses ultraviolet light to excite a catalyst and promote chemical reactions to purify waste gas and wastewater. It uses specially designed high-energy ultraviolet light to irradiate waste gas or wastewater, breaking down the molecular chain structure and degrading organic or inorganic polymers into low-molecular-weight compounds such as carbon dioxide and water. In addition, a catalyst is added during the wastewater treatment process to enhance the oxidation-reduction reaction and further degrade organic pollutants.
[0003] Currently, most ultraviolet (UV) tubes are placed in fixed positions, resulting in excessively strong light in some areas and insufficient light in others. Furthermore, without reflective treatment, a large amount of UV light escapes due to reflection, which restricts the photocatalytic oxidation effect and makes it difficult to meet the demand for high-efficiency catalysis of wastewater. In view of this, we propose a high-efficiency photocatalytic treatment device with optimized UV light distribution. Utility Model Content

[0005] To solve the above technical problems, this utility model provides the following technical solution: a high-efficiency photocatalytic treatment device with optimized ultraviolet light distribution, including a photocatalytic device and a reaction chamber set inside the photocatalytic device, wherein a first reflective sticker for light reflection is fixedly connected to the inner wall of the reaction chamber, and a plurality of lamp tube bodies are set at the bottom of the inner wall of the reaction chamber. The bottom of the reaction chamber is provided with a stirring mechanism, which includes a rotating shaft and a transmission shaft connected to the top of the rotating shaft by a pin. The outer walls on both sides of the rotating shaft are provided with fitting grooves. The outer wall of the drive shaft is provided with a flow guiding device, which includes a turntable and a first blade. The turntable also includes two interlocking blocks for transmitting power. The interlocking blocks are located inside the interlocking groove. The first blade drives the liquid in the middle of the reaction chamber to flow towards the stirring mechanism. Floating blocks are fixedly connected to both sides of the top of the turntable. The flow guiding device also includes a flow reversal mechanism, which includes a support ring and an arc-shaped protrusion. The outer wall of the arc-shaped protrusion is fixedly connected with a second reflective sticker for light reflection. The support ring has a flow reversal hole for liquid flow around the periphery of the reaction chamber. Several second blades are fixedly connected to the inner wall of the flow reversal hole. Support frames are fixedly connected to both sides of the top surface of the support ring.
[0006] Preferably, a water inlet pipe is provided on one side of the outer wall of the photocatalytic device, and a drain pipe is provided on the outer wall of the photocatalytic device on the side opposite to the water inlet pipe. The water inlet end of the drain pipe is located at the bottom of the reaction chamber, and both the water inlet pipe and the drain pipe are connected to the inside of the reaction chamber. The top surface of the photocatalytic device is equipped with a dosing device for adding catalyst.
[0007] Preferably, the four corners of the inner wall of the reaction chamber are designed with an arc-shaped structure, and the lamp bodies are arranged in a rectangular array.
[0008] Preferably, a plurality of stirring blades for driving fluid flow are fixedly connected to the outer wall of the rotating shaft, and the stirring blades are located at the bottom of the reaction chamber. A through hole is provided at the center of the turntable, the rotating shaft is located inside the through hole, and the two fitting blocks are fixedly connected to the inner wall of the through hole.
[0009] Preferably, the protrusion direction of the arc-shaped protrusion faces the bottom surface of the reaction chamber, the top surface of the arc-shaped protrusion is fixedly connected to the bottom surface of the support ring, and a plurality of the arc-shaped protrusions are distributed in a circular array.
[0010] Preferably, the support ring is located outside the lamp tube body, the end of the support frame away from the support ring is bolted to the top surface of the turntable, the support frame adopts a U-shaped structure design, and the top surface of the support frame is higher than the top of the lamp tube body.
[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model achieves multi-directional reflection by designing a first reflective sticker on the inner wall of the reaction chamber and a second reflective sticker on the outer wall of the arc-shaped protrusion, reducing ultraviolet light escape and compensating for the light waste problem of traditional devices. The arc-shaped structure at the four corners of the reaction chamber, combined with the rectangular array of lamp bodies, avoids dead angles in illumination. The circular array layout of the arc-shaped protrusion further ensures that the reflected light evenly covers all areas of the chamber, improving the core problem of excessive or insufficient local illumination and solving the problem of poor uniformity of ultraviolet light distribution affecting the efficiency of catalytic reaction.
[0012] 2. This utility model also prevents catalyst precipitation by designing the stirring blades of the stirring mechanism. The first blade drives the liquid in the middle to flow to the bottom, and the second blade guides the liquid on the peripheral wall to flow back, forming a complete cycle. This allows the liquid to fully contact the catalyst and ultraviolet light. In addition, the float allows the flow guiding device to adaptively adjust its height according to the liquid level, ensuring effective flow guiding at different liquid levels. This improves the adaptability of the device to different processing volumes and further solves the problem of low catalytic reaction efficiency. Attached Figure Description

[0015] like Figures 1 to 7As shown, this utility model relates to a high-efficiency photocatalytic treatment device for optimized ultraviolet light distribution, including a photocatalytic device 1 and a reaction chamber 14 disposed inside the photocatalytic device 1. A first reflective sticker 16 for light reflection is fixedly connected to the inner wall of the reaction chamber 14. Several lamp tube bodies 15 are disposed at the bottom end of the inner wall of the reaction chamber 14. A stirring mechanism 2 is disposed at the bottom end of the reaction chamber 14. The stirring mechanism 2 includes a rotating shaft 21 and a transmission shaft 23 connected to the top of the rotating shaft 21 by a pin. Fitting grooves 24 are opened on both sides of the outer wall of the rotating shaft 21. A flow guiding device 3 is disposed on the outer wall of the transmission shaft 23. The flow guiding device 3 includes a turntable 31 and a first blade 34. The turntable 31 also includes two... A power transmission interlocking block 33 is located inside the interlocking groove 24. The first impeller 34 drives the liquid in the middle of the reaction chamber 14 to flow towards the stirring mechanism 2. Float blocks 35 are fixedly connected to both sides of the top of the turntable 31. The flow guiding device 3 also includes a flow reversal mechanism 4. The flow reversal mechanism 4 includes a support ring 41 and an arc-shaped protrusion 45. A second reflective sticker 46 for light reflection is fixedly connected to the outer wall of the arc-shaped protrusion 45. Flow reversal holes 43 for liquid flow around the periphery of the reaction chamber 14 are opened inside the support ring 41. Several second impellers 44 are fixedly connected to the inner wall of the flow reversal holes 43. Support frames 42 are fixedly connected to both sides of the top surface of the support ring 41. The first reflective sticker 16 reflects ultraviolet light from the reaction chamber 14, reducing light escape and improving light utilization. The second reflective sticker 46 works with the first reflective sticker 16 to form multi-directional reflection, further optimizing the distribution of ultraviolet light and avoiding insufficient local illumination. The cooperation between the interlocking block 33 and the interlocking groove 24 enables stable power transmission, ensuring synchronous operation of the drive shaft 23 and the rotating shaft 21, guaranteeing stirring and guiding effects. The first impeller 34 drives the liquid in the middle of the reaction chamber 14 to flow towards the stirring mechanism 2, promoting liquid circulation and allowing the liquid to have more complete contact with the catalyst and ultraviolet light. The float 35 enables the guiding device 3 to adaptively adjust its height according to changes in the liquid level in the reaction chamber 14, always maintaining a positive effect on the liquid. The first impeller 34 effectively guides the flow of liquid. The reflux hole 43 provides a flow channel for the liquid on the periphery of the reaction chamber 14, preventing liquid stagnation and ensuring overall liquid circulation efficiency. The second impeller 44 can assist in driving the liquid on the periphery to flow back through the reflux hole 43, enhancing liquid turbulence. Thus, when the catalyst flows from the dosing device 11 into the liquid surface of the reaction chamber 14, the first impeller 34 drives the liquid in the middle of the reaction chamber 14 to flow downward until the liquid flows to the stirring blade 22. The stirring blade 22 stirs and mixes the liquid. Then, the liquid in the middle diffuses outward, while the second impeller 44 rotates synchronously, guiding the liquid in the circumferential direction inside the reaction chamber 14 upward to the liquid surface, thus achieving the purpose of liquid circulation inside the reaction chamber 14.
[0016] Specifically, a water inlet pipe 12 is provided on one side of the outer wall of the photocatalytic device 1, and a drain pipe 13 is provided on the other side of the outer wall of the photocatalytic device 1, opposite to the water inlet pipe 12. The water inlet end of the drain pipe 13 is located at the bottom of the reaction chamber 14. Both the water inlet pipe 12 and the drain pipe 13 are connected to the inside of the reaction chamber 14. A dosing device 11 for adding catalyst is provided on the top surface of the photocatalytic device 1. The water inlet pipe 12 facilitates the entry of the liquid to be treated into the reaction chamber 14, and the drain pipe 13 facilitates the discharge of the treated liquid. The water inlet end of the drain pipe 13 is located at the bottom of the reaction chamber 14, which can fully discharge the liquid in the reaction chamber 14. The dosing device 11 facilitates the precise addition of catalyst, thereby improving the reaction efficiency. The dosing device 11 includes a monitoring sensor integrated into the reaction chamber 14, a dosing pump connected to the reagent tank, and a control module. The control module adjusts the switch and flow rate of the dosing pump according to the real-time data of the sensor to achieve precise dosing and monitoring, ensuring that the amount of catalyst incorporated into the liquid in the reaction chamber 14 meets the photocatalytic requirements.
[0017] Furthermore, the four corners of the inner wall of the reaction chamber 14 are designed with an arc shape, and several lamp tubes 15 are arranged in a rectangular array. The arc shape at the four corners of the inner wall of the reaction chamber 14 can avoid the formation of blind spots in the corners, ensuring that all areas in the chamber can receive ultraviolet light. The rectangular array of lamp tubes 15 can initially guarantee the ultraviolet light coverage, laying the foundation for subsequent optimized distribution of light reflection, and reducing the situation of excessively strong or weak local illumination. Several lamp tubes 15 are installed parallel to the axis of the reaction chamber 14.
[0018] It is worth noting that several stirring blades 22 for driving fluid flow are fixedly connected to the outer wall of the rotating shaft 21. The stirring blades 22 are located at the bottom of the reaction chamber 14. A through hole 32 is opened at the center of the turntable 31, and the rotating shaft 21 is located inside the through hole 32. Two fitting blocks 33 are fixedly connected to the inner wall of the through hole 32. The stirring blades 22 can agitate the liquid at the bottom of the reaction chamber 14, prevent the catalyst from settling at the bottom, and ensure that the catalyst and liquid are mixed evenly. The design of the through hole 32 allows the rotating shaft 21 to pass through the turntable 31, making the structure of each component more compact and saving internal space in the reaction chamber 14. The fixed connection between the fitting blocks 33 and the inner wall of the through hole 32 can enhance the stability of the fitting blocks 33, prevent the fitting blocks 33 from falling off during power transmission, and improve the operational stability of the device. A variable frequency motor is set at the bottom of the rotating shaft 21, which can realize the speed adjustment of the stirring blades 22 to adapt to different material viscosities and ensure that the material is mixed evenly.
[0019] It is worth noting that the protruding direction of the arc-shaped protrusion 45 faces the bottom surface of the reaction chamber 14, and the top surface of the arc-shaped protrusion 45 is fixedly connected to the bottom surface of the support ring 41. Several arc-shaped protrusions 45 are distributed in a circular array. The protruding direction of the arc-shaped protrusion 45 facing the bottom surface can reflect ultraviolet light to the lower part of the reaction chamber 14, reducing the amount of ultraviolet light irradiating the top of the reaction chamber 14 and compensating for the insufficient lighting at the bottom. The fixed connection between the arc-shaped protrusion 45 and the support ring 41 can improve the stability of the arc-shaped protrusion 45. The circular array of arc-shaped protrusions 45 can make the reflected light evenly cover the circumferential area of the reaction chamber 14, further optimizing the uniformity of ultraviolet light distribution.
[0020] It is worth noting that the support ring 41 is located outside the lamp tube body 15, and the end of the support frame 42 away from the support ring 41 is bolted to the top surface of the turntable 31. The support frame 42 adopts a U-shaped structure design, and the top surface of the support frame 42 is higher than the top of the lamp tube body 15. The support ring 41 is located outside the lamp tube body 15 to prevent the support ring 41 from colliding and damaging the lamp tube body 15. The support frame 42 is connected to the turntable 31 by bolts, which facilitates subsequent disassembly and maintenance. The U-shaped structure of the support frame 42 can reduce its own weight while ensuring support strength, thereby reducing the resistance to the operation of the air guiding device 3. The top surface of the support frame 42 is higher than the top of the lamp tube body 15, which can prevent the support frame 42 from colliding with the lamp tube body 15 and ensure normal light propagation.
[0021] Working Principle: This embodiment provides a high-efficiency photocatalytic treatment device with optimized ultraviolet light distribution. During use, the liquid to be treated enters the reaction chamber 14 of the photocatalytic device 1 through the inlet pipe 12. Simultaneously, a catalyst is precisely added to the reaction chamber 14 through the dosing device 11. The control module of the dosing device 11 adjusts the on / off state and flow rate of the dosing pump based on real-time data from monitoring sensors integrated in the reaction chamber 14, ensuring that the catalyst dosage meets the photocatalytic requirements. Subsequently, several lamp bodies 15, arranged in a rectangular array and installed parallel to the axis of the reaction chamber 14, are activated, releasing ultraviolet light for... The catalyst is activated to promote the photocatalytic reaction. The first reflective patch 16 fixed to the inner wall of the reaction chamber 14 reflects the ultraviolet light inside the chamber, reducing light escape. Meanwhile, the second reflective patch 46 on the outer wall of the arc-shaped protrusion 45 in the counterflow mechanism 4 works with the first reflective patch 16 to form multi-directional reflection. The arc-shaped protrusions 45 are arranged in a circular array with their protrusions facing the bottom surface of the reaction chamber 14, which can reflect ultraviolet light to the lower part of the reaction chamber 14, compensating for insufficient light at the bottom. At the same time, the arc-shaped structure at the four corners of the inner wall of the reaction chamber 14 avoids the formation of irradiation dead zones in the corners, further optimizing the uniformity of ultraviolet light distribution. The variable frequency motor at the bottom of the rotating shaft 21 starts, driving the rotating shaft 21 and the stirring blades 22 on the outer wall to rotate. The rotating shaft 21, through the fitting grooves 24 on both sides, cooperates with the fitting blocks 33 of the turntable 31 to transmit power to the transmission shaft 23, thereby driving the entire flow guiding device 3 to operate. The float 35 at the top of the turntable 31 enables the flow guiding device 3 to adaptively adjust its height according to the changes in the liquid level in the reaction chamber 14, always maintaining effective flow guidance. During operation, the first blade 34 drives the liquid in the middle of the reaction chamber 14 to flow towards the stirring mechanism 2. The liquid flowing to the bottom of the reaction chamber 14 is fully stirred by the stirring blades 22 to prevent... Catalyst precipitation achieves uniform mixing of catalyst and liquid. Subsequently, the mixed liquid diffuses circumferentially in the middle. At the same time, the support ring 41 of the counterflow mechanism 4 rotates synchronously with the turntable 31. The second blade 44 on the inner wall of the counterflow hole 43 inside the support ring 41 assists in driving the liquid on the periphery of the reaction chamber 14 to flow upward to the liquid surface through the counterflow hole 43, forming a circulating flow of liquid inside the reaction chamber 14. This allows the liquid, catalyst and ultraviolet light to fully contact each other, improving the efficiency of photocatalytic reaction. After the reaction is completed, the treated liquid is discharged from the photocatalytic device 1 through the drain pipe 13 at the bottom of the reaction chamber 14.
