Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, specifically to a photocatalytic treatment device with a film loaded with photocatalytic material. Background Technology

[0002] Currently, in the research and application of photocatalysis technology in water bodies, photocatalytic materials are mostly small-scale structures such as particles, powders, and sheets, such as titanium dioxide (TiO2) powder and carbon nitride (C3N4) nanosheets. When these materials are introduced into water bodies, they can trigger photocatalytic reactions under specific wavelengths of light incident at specific angles. Since the photocatalytic process requires no additional energy consumption, it possesses green and energy-saving advantages, making it a research hotspot in the field of water treatment. In recent years, with researchers' continuous exploration of photocatalytic material development and modification processes, photocatalysis technology has achieved significant improvements in the treatment of organic pollutants in water bodies and the efficiency of hydrogen peroxide (H2O2) preparation, showing increasingly broad application prospects.

[0003] However, the photocatalytic water treatment device disclosed in Chinese Patent No. CN217732873U, although it achieves contact between the photocatalyst and light through the design of "microporous photocatalyst loaded on the outer surface of the membrane tube and ultraviolet light-emitting diodes surrounding the membrane tube", and extends the water flow residence time by means of baffles, still has the following shortcomings: First, the utilization of light is limited. The light emitted by its ultraviolet light-emitting diodes only acts on the photocatalyst on the surface of the membrane tube through direct irradiation. There is no light reflection structure. Some light is dissipated without participating in the photocatalytic reaction, and the light utilization rate needs to be further improved. Second, the maintenance and recycling of the membrane tube is inconvenient. Its membrane tube is fixed longitudinally in the reactor tank and sealed with the upper and lower end caps. The upper end cap must be removed to replace or recycle the membrane tube, which is cumbersome. Moreover, the whole device is a closed tank structure, which is not conducive to the flexible disassembly and maintenance of components. Utility Model Content

[0004] The purpose of this invention is to provide a photocatalytic treatment device with a loaded photocatalytic material membrane to solve the problems of existing devices, such as limited light utilization, ultraviolet light from LEDs only directly irradiating the photocatalyst on the surface of the membrane tube without a reflective structure, resulting in some light being dissipated without participating in the reaction and the need to improve utilization rate; inconvenient maintenance and recycling of the membrane tube, as the membrane tube is fixed longitudinally to a closed tank and requires the removal of the top cover for replacement or recycling, which is cumbersome and not conducive to flexible disassembly and maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a photocatalytic treatment device loaded with a photocatalytic material membrane, comprising a stainless steel platform, an ultraviolet irradiation device covering the upper side of the stainless steel platform and used to provide light to the photocatalytic material, and further comprising a plurality of polished arc-shaped reflective grooves horizontally spaced along the length of the stainless steel platform, recyclable photocatalytic membrane tubes respectively embedded in the plurality of polished arc-shaped reflective grooves and loaded with photocatalytic material membranes, a water inlet pipe sealed and connected to the liquid inlet port of the recyclable photocatalytic membrane tube at the first end, a valve provided on the water inlet pipe section, and a valve connected to the recyclable membrane tube at the tail end. The system includes a water outlet pipe with a sealed connection to the liquid outlet port of the photocatalytic membrane tube, and a connecting pipe for connecting two adjacent recyclable photocatalytic membrane tubes.

Both ends of the multiple recyclable photocatalytic membrane tubes are detachably connected to the upper sides of the stainless steel platform, and the liquid inlet and outlet ports of the multiple recyclable photocatalytic membrane tubes are alternately arranged along the length of the stainless steel platform. The multiple polished arc-shaped reflective grooves are used to reflect the light from the ultraviolet irradiation device to enhance light utilization.

[0006] Furthermore, the recyclable photocatalytic membrane tube includes two axially symmetrically arranged stainless steel end caps, a quartz tube located on the inner side of the two stainless steel end caps and coaxially arranged, a metal mesh tube located inside one side of the stainless steel end cap and inside the quartz tube, a photocatalytic material membrane loaded on the outside of the metal mesh tube, and a sealing end cap covering the metal mesh tube near the other stainless steel end cap; one side of the stainless steel end cap connected to the metal mesh tube is connected to the outlet port of the water outlet pipe or connecting pipe; one side of the other stainless steel end cap is connected to the inlet port of the water inlet pipe or connecting pipe; both ends of the quartz tube are respectively sealed to the inner walls of the two stainless steel end caps, the quartz tube is located inside the corresponding polished arc-shaped reflective groove, and the axis of the quartz tube is parallel to the center line of the arc surface of the polished arc-shaped reflective groove.

[0007] Furthermore, a row of slots is formed on both sides of the stainless steel platform along its length, and the two rows of slots are symmetrically distributed along the width of the stainless steel platform. Each row of slots has multiple slots spaced apart along the length of the stainless steel platform, and two slots opposite each other along the width of the stainless steel platform are respectively connected to the two ends of a polished arc-shaped reflective groove. The bottom of the slot is an arc shape adapted to the outer wall of the stainless steel end cap, and the radius of the arc surface of the slot is consistent with the radius of the outer wall of the stainless steel end cap. The two stainless steel end caps of the recyclable photocatalytic membrane tube are respectively embedded in the two slots opposite each other along the width of the stainless steel platform. The upper two sides of the stainless steel platform are provided with clamping and fixing components for holding and fixing the stainless steel end caps. The two stainless steel end caps of the recyclable photocatalytic membrane tube are respectively held and fixed in the corresponding slots by the two clamping and fixing components.

[0008] Furthermore, the clamping and fixing assembly includes a mounting plate that fits tightly against the upper edge of the stainless steel platform, a plurality of set screws threaded to the mounting plate along the length of the mounting plate, and screws threaded to both ends of the upper side of the mounting plate respectively; one end of the set screw extending to the lower side of the mounting plate abuts against the top of the outer wall of the corresponding stainless steel end cap, the number of set screws is consistent with the number of slots in a row, and a single set screw and a single slot are aligned vertically; the mounting plate is detachably connected to the upper edge of the stainless steel platform by two screws.

[0009] Furthermore, the ultraviolet irradiation device includes a gantry frame shaped like a portal frame located at both ends of the upper side of the stainless steel platform, a light source lifting mechanism located on the upper side of the gantry frame, a mounting cover connected to the light source lifting mechanism, multiple ultraviolet lamps located on both sides inside the mounting cover and horizontally spaced along its length, slide rails located on both sides inside the gantry frame, and sliders that slide in cooperation with the slide rails; two sliders are respectively connected to both sides of the mounting cover, and the sliding cooperation direction between the sliders and the slide rails is set in the vertical direction; the ultraviolet lamps are used to emit ultraviolet light to excite the photocatalytic material film to undergo a photocatalytic reaction.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention relates to a photocatalytic treatment device for loading photocatalytic material membranes. By incorporating a polished arc-shaped reflective groove on the upper side of a stainless steel platform, and a UV irradiation device mounted above it, the portion of the light emitted by the UV irradiation device that does not directly affect the recyclable photocatalytic membrane tube is reflected back to the surface of the recyclable photocatalytic membrane tube. This effectively reduces light energy dissipation, improves light utilization, ensures the photocatalytic material membrane fully receives excitation light, and guarantees photocatalytic reaction efficiency. Furthermore, the two ends of the recyclable photocatalytic membrane tube are detachably connected to the two sides of the upper side of the stainless steel platform, allowing for disassembly, replacement, and recycling of the recyclable photocatalytic membrane tube without disassembling the overall enclosed structure. Simultaneously, the UV irradiation device is independently mounted above the treatment platform, separated from the liquid treatment area. During inspection or maintenance, there is no need to contact the liquid transport components, significantly reducing maintenance difficulty and time costs. The separation of the UV irradiation device from the liquid treatment area avoids direct contact between the liquid and the irradiation components, reducing the risk of liquid corrosion.

[0014] Please see Figure 1-6 A photocatalytic treatment device loaded with a photocatalytic material membrane includes a stainless steel platform 1, an ultraviolet irradiation device covering the upper side of the stainless steel platform 1 for providing light to the photocatalytic material, a plurality of polished arc-shaped reflective grooves 2 horizontally spaced along the length of the stainless steel platform 1 and located on the upper side of the stainless steel platform 1, recyclable photocatalytic membrane tubes 11 respectively embedded in the plurality of polished arc-shaped reflective grooves 2 and loaded with photocatalytic material membranes inside, a water inlet pipe 12 sealed and connected to the liquid inlet port of the first end of the recyclable photocatalytic membrane tube 11, a valve 13 provided on the water inlet pipe 12, and a valve connecting the end of the recyclable photocatalytic membrane tube 11 to the outlet of the second end of the recyclable photocatalytic membrane tube 11. The system includes a liquid outlet pipe 15 with a sealed liquid port, a connecting pipe 14 for connecting two adjacent recyclable photocatalytic membrane components 11, one end of which is sealed to the liquid outlet port of the preceding recyclable photocatalytic membrane component 11, and the other end of which is sealed to the liquid inlet port of the following recyclable photocatalytic membrane component 11; both ends of the multiple recyclable photocatalytic membrane components 11 are detachably connected to the upper sides of the stainless steel platform 1, and the liquid inlet and outlet ports of the multiple recyclable photocatalytic membrane components 11 are alternately arranged along the length of the stainless steel platform 1; and multiple polished arc-shaped reflective grooves 2 are used to reflect the light from the ultraviolet irradiation device to enhance light utilization.

[0015] This application further proposes that the recyclable photocatalytic membrane tube 11 includes two axially symmetrically arranged stainless steel end caps 19, a quartz tube 20 disposed on the inner side of the two stainless steel end caps 19 and coaxially arranged, a metal mesh tube 21 disposed on one side inside one stainless steel end cap 19 and located inside the quartz tube 20, a photocatalytic material membrane loaded on the outside of the metal mesh tube 21, and a sealing end cap 22 covering the side of the metal mesh tube 21 near the other stainless steel end cap 19; one side of one stainless steel end cap 19 connected to the metal mesh tube 21 is connected to the outlet port of the outlet pipe 15 or the connecting pipe 14; one side of the other stainless steel end cap 19 is connected to the inlet port of the inlet pipe 12 or the connecting pipe 14; both ends of the quartz tube 20 are respectively sealed to the inner walls of the two stainless steel end caps 19, the quartz tube 20 is located inside the corresponding polished arc-shaped reflective groove 2, and the axis of the quartz tube 20 is parallel to the center line of the arc surface of the polished arc-shaped reflective groove 2.

[0016] The two ends of the quartz tube 20 are sealed to the inner walls of the two stainless steel end caps 19 by means of sealant or sealing ring; the outer wall of the metal mesh tube 21 is loaded with a photocatalytic material film by coating or impregnation; the stainless steel end cap 19 connected to the metal mesh tube 21 has an interface on its outer wall, which can be connected to the water outlet port of the water outlet pipe 15 or the connecting pipe 14; the outer wall of the other stainless steel end cap 19 also has an interface, which can be connected to the water inlet port of the water inlet pipe 12 or the connecting pipe 14.

[0017] Specifically, the quartz tube 20 has excellent light transmittance, allowing ultraviolet light to efficiently penetrate and act on the photocatalytic material membrane on the outside of the metal mesh tube 21. Simultaneously, the sealed connection between the quartz tube 20 and the stainless steel end cap 19 prevents leakage of the liquid to be treated, ensuring a tight seal during transport. Furthermore, the metal mesh tube 21, as a carrier of the photocatalytic material membrane, possesses both good structural strength and increases the contact area between the membrane and the liquid. The membrane is loaded on the outside, facilitating subsequent inspection and replacement during recycling. The sealing end cap 22 covers the end of the metal mesh tube 21, allowing the liquid to pass through efficiently. The liquid being processed permeates through the mesh of the metal mesh cylinder 21 and flows into its interior. After passing through the interior, it enters the next recyclable photocatalytic membrane tube 11 through the interface of the corresponding stainless steel end cap 19. This forces the liquid to fully contact the photocatalytic material membrane loaded on the outside of the metal mesh cylinder 21, preventing the liquid from flowing directly through the outside of the quartz tube 20 without undergoing a photocatalytic reaction, thus ensuring the liquid purification effect. The matching layout of the quartz tube 20 and the polished arc-shaped reflective groove 2 can fully utilize the reflected ultraviolet light to further stimulate the photocatalytic reaction and improve the overall processing efficiency.

[0018] This application further proposes that a row of slots 3 are formed on both sides of the stainless steel platform 1 along its own length direction, and the two rows of slots 3 are symmetrically distributed along the width direction of the stainless steel platform 1; each row of slots 3 has multiple slots spaced apart along the length direction of the stainless steel platform 1, and two slots 3 opposite each other along the width direction of the stainless steel platform 1 are respectively connected to the two ends of a polished arc-shaped reflective groove 2; the bottom of the slot 3 is an arc shape adapted to the outer wall of the stainless steel end cap 19, and the radius of the arc surface of the slot 3 is consistent with the radius of the outer wall of the stainless steel end cap 19; the two stainless steel end caps 19 of the recyclable photocatalytic membrane tube 11 are respectively embedded in the two slots 3 opposite each other along the width direction of the stainless steel platform 1; the upper two sides of the stainless steel platform 1 are provided with clamping and fixing components for holding and fixing the stainless steel end caps 19; the two stainless steel end caps 19 of the recyclable photocatalytic membrane tube 11 are respectively held and fixed in the corresponding slots 3 by the two clamping and fixing components.

[0019] The bottom of the slot 3 is machined into an arc surface that fits the outer wall of the stainless steel end cap 19, and the radius of the arc surface of the slot 3 is exactly the same as the radius of the outer wall of the stainless steel end cap 19, ensuring that the stainless steel end cap 19 can be installed in the slot 3.

[0020] Specifically, the structure in which the slot 3 and the polished arc-shaped reflective groove 2 are connected one-to-one at both ends allows the quartz tube 20 of the recyclable photocatalytic membrane tube 11 to be embedded in the polished arc-shaped reflective groove 2, ensuring the reflection effect of the polished arc-shaped reflective groove 2 on ultraviolet light and improving the light utilization rate of the photocatalytic material membrane.

[0021] This application further proposes that the clamping and fixing assembly includes a mounting plate 16 that is tightly fitted to the upper edge of the stainless steel platform 1, a plurality of set screws 17 that are threaded to the mounting plate 16 along the length of the mounting plate 16, and screws 18 that are threaded to both ends of the upper side of the mounting plate 16 respectively; one end of the set screw 17 extends to the lower side of the mounting plate 16 and abuts against the top of the outer wall of the corresponding stainless steel end cap 19, the number of set screws 17 is consistent with the number of a row of slots 3, and a single set screw 17 and a single slot 3 are aligned in the vertical direction; the mounting plate 16 is detachably connected to the upper edge of the stainless steel platform 1 by two screws 18.

[0022] The mounting plate 16 is long and narrow; the lower end of the set screw 17 is fixedly connected to a rubber pad to avoid rigid contact between the set screw 17 and the stainless steel end cap 19, and to prevent the set screw 17 from being tightened too much and causing indentations or damage to the outer wall of the stainless steel end cap 19.

[0023] Specifically, the screws 18, mounting plate 16, and set screws ensure the stable assembly of the mounting plate 16 on the stainless steel platform 1, while the set screws 17 hold the stainless steel end cap 19 in the slot 3, preventing the recyclable photocatalytic membrane tube 11 from shaking or shifting during liquid flow. At the same time, the mounting plate 16 is detachably connected by the screws 18, and the set screws 17 can be turned in the opposite direction to release the hold. When disassembling or replacing the recyclable photocatalytic membrane tube 11, there is no need to damage the overall structure, reducing maintenance costs.

[0024] This application further proposes that the ultraviolet irradiation device includes a gantry frame 4 with a portal shape located at both ends of the upper side of the stainless steel platform 1, a light source lifting mechanism located on the upper side of the gantry frame 4, a mounting cover 5 that is connected to the light source lifting mechanism, a plurality of ultraviolet lamps 6 located on both sides inside the mounting cover 5 and arranged horizontally at intervals along its length, slide rails 8 located on both sides inside the gantry frame 4 respectively, and sliders 7 that slide in cooperation with the slide rails 8; the two sliders 7 are respectively connected to both sides of the mounting cover 5, and the sliding cooperation direction between the sliders 7 and the slide rails 8 is set in the vertical direction; the ultraviolet lamps 6 are used to emit ultraviolet light to excite the photocatalytic material film to undergo a photocatalytic reaction.

[0025] The mounting cover 5 is a cover structure with an opening at the bottom. The axis of the ultraviolet lamp tube 6 is parallel to the axis of the recyclable photocatalytic membrane tube 11. The gantry 4 is fixedly connected to the upper side of the stainless steel platform 1 by screws. When the photocatalytic water (H2O) chemical reaction experiment needs to be carried out using natural light, multiple screws can be unscrewed to remove the gantry 4 from the stainless steel platform 1 so that the experiment can proceed smoothly.

[0026] Specifically, the gantry frame 4 provides stable support and can fully cover the recyclable photocatalytic membrane tube 11 on the upper side of the stainless steel platform 1, ensuring that there are no blind spots in the ultraviolet light irradiation; multiple ultraviolet lamps 6 are spaced apart and symmetrically arranged along the length of the mounting cover 5, so that the ultraviolet light can be evenly applied to the outside of the metal mesh tube 21 of each recyclable photocatalytic membrane tube 11.

[0027] This application further proposes that the light source lifting mechanism includes an adjusting screw 9 arranged vertically and threaded through the upper side of the gantry 4, and a handwheel 10 fixedly connected to the upper end of the adjusting screw 9 and located above the gantry 4; the lower end of the adjusting screw 9 is rotatably connected to the upper side of the mounting cover 5 through the middle of the bearing.

[0028] Specifically, turning the handwheel 10 will drive the adjusting screw 9 to rise and fall along the threaded hole on the upper side of the gantry 4, thereby pushing the mounting cover 5 to move. The distance between the ultraviolet lamp tube 6 and the recyclable photocatalytic membrane tube 11 can be flexibly adjusted according to the photocatalytic reaction requirements to ensure that the ultraviolet light acts on the photocatalytic material membrane at the optimal angle and intensity.

[0029] Working process and principle: When the device is working, the stainless steel end caps 19 at both ends of the recyclable photocatalytic membrane tube 11 are respectively embedded into the symmetrical slots 3 on both sides of the stainless steel platform 1. Then, the mounting plate 16 is attached to the upper edge of the stainless steel platform 1 and fixed with screws 18. Then, the set screw 17 on the mounting plate 16 is turned so that the lower end of the set screw 17 presses against the top of the outer wall of the stainless steel end cap 19, thereby realizing the assembly of the recyclable photocatalytic membrane tube 11. The liquid inlet and liquid outlet ports of each recyclable photocatalytic membrane tube 11 are arranged alternately along the length of the stainless steel platform 1 and connected in series through the connecting pipe 14. The first recyclable photocatalytic membrane tube 11 is connected to the water inlet pipe 12 and the last recyclable photocatalytic membrane tube 11 is connected to the water outlet pipe 15.

[0030] Before starting the device, turn the handwheel 10 according to the photocatalytic reaction requirements. The handwheel 10 drives the adjusting screw 9 to rotate around its own axis. When the adjusting screw 9 rotates, it rises and falls in the vertical direction, thereby driving the mounting cover 5 to rise and fall along the slide rail 8 (which cooperates with the slider 7) on the inner side of the gantry frame 4, until the ultraviolet lamp tube 6 inside the mounting cover 5 is at the appropriate light illumination height.

[0031] During operation, valve 13 on the inlet pipe 12 and the circulation pump on the liquid to be treated delivery pipeline are opened. Under the power of the circulation pump, the liquid to be treated sequentially enters the recyclable photocatalytic membrane tube 11 through the inlet pipe 12 and the inlet ports of each recyclable photocatalytic membrane tube 11. When the liquid flows past the outside of the metal mesh tube 21 (the metal mesh tube 21 is loaded with photocatalytic material membrane), the ultraviolet lamp 6 is turned on. The ultraviolet lamp 6 emits ultraviolet light, part of which directly irradiates the photocatalytic material membrane on the upper part of the outside of the metal mesh tube 21, and the other part of the ultraviolet light is reflected by the polished arc-shaped reflective groove 2 on the stainless steel platform 1. The photocatalytic material membrane on the lower outer side of the metal mesh cylinder 21 is activated to fully stimulate the photocatalytic reaction and purify the flowing liquid. The initially purified liquid permeates through the mesh of the metal mesh cylinder 21 into the interior of the metal mesh cylinder 21, and then connects to the connecting pipe 14 through the interface of the corresponding stainless steel end cap 19, entering the next recyclable photocatalytic membrane tube 11 for further purification. This process continues, with the liquid passing through each recyclable photocatalytic membrane tube 11 in sequence, and then flowing into the water outlet pipe 15 from the liquid outlet port of the recyclable photocatalytic membrane tube 11 at the tail end, finally completing the purification and being discharged. If it is necessary to replace or recycle the recyclable photocatalytic membrane tube 11, simply reverse the top screw 17 and remove the mounting plate 16 by unscrewing the top screw 17 and removing the mounting screw 18 to remove the recyclable photocatalytic membrane tube 11 from the slot 3. The operation is convenient.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
