Description

Technical Field

[0001] This utility model relates to the field of photocatalytic reaction technology, and in particular to a multi-channel photocatalytic-ultrasonic piezoelectric coupling reaction device. Background Technology

[0002] Photocatalytic reactors are devices used to realize reaction processes and have wide applications in chemical and other fields. They are commonly used to achieve single-phase liquid reactions and multiphase reactions such as liquid-liquid, gas-liquid, liquid-solid, and gas-liquid-solid reactions. Currently, most commonly used photocatalytic reactors are single photocatalytic reaction systems, i.e., an open container placed on a magnetic stirrer, where the reaction liquid reacts under ultraviolet irradiation. This type of reactor has low light source utilization efficiency and low catalytic processing efficiency. To address this, existing technologies, such as the multi-channel photocatalytic reaction device disclosed in Chinese patent document CN220940674U, use three photocatalytic reaction tubes, each with an ultraviolet lamp at both ends, ensuring uniform illumination of each tube and significantly improving catalytic efficiency and throughput. The ultraviolet light source between two photocatalytic reaction tubes can simultaneously irradiate both tubes, improving light source utilization. However, the catalyst, located inside the photocatalytic reaction tube, is prone to aggregation, which affects the contact efficiency between the reactants and the catalyst, thus impacting the stability and repeatability of the photocatalytic reaction. Utility Model Content

[0003] In view of this, the purpose of this utility model is to propose a multi-channel photocatalytic-ultrasonic piezoelectric coupling reaction device to solve one or more of the problems mentioned above.

[0004] To achieve the above objectives, this utility model provides a multi-channel photocatalytic-ultrasonic piezoelectric coupling reaction device, comprising a cooling water circulation system and a photocatalytic reaction system. The cooling water circulation system includes a low-temperature constant temperature bath, an inlet pipe, and an outlet pipe. The photocatalytic reaction system includes a reaction tank and a photocatalytic reaction tube. The low-temperature constant temperature bath is connected to an inlet at one end of the reaction tank via the inlet pipe, and the low-temperature constant temperature bath is connected to an outlet at the other end of the reaction tank via the outlet pipe.

[0005] The side end of the reaction tank is equipped with a movable transverse mechanism, which is equipped with an ultrasonic component. The movable transverse mechanism drives the ultrasonic component to move laterally to different positions along the length of the side end of the reaction tank, thereby generating ultrasonic vibrations inside the reaction tank.

[0006] Preferably, a rectangular opening is provided at the side end of the reaction tank. A horizontal sealing strip and a vertical sealing strip are respectively attached to the four outer sides of the opening. A sliding groove is symmetrically provided on the upper and lower sides of the opening. The horizontal sealing strip is located inside the sliding groove. The movable transverse movement mechanism includes multiple movable plates, at least one of which is provided with an ultrasonic component. The component slides and inserts along the sliding groove through the top and bottom edges of the movable plate until the opening is closed by the adjacent movable plates in sequence.

[0007] Preferably, the groove is designed in an L-shape.

[0008] Preferably, the slide is provided with a locking bolt, the shank of which penetrates into the inside of the slide. By tightening the locking bolt, the shank of the locking bolt presses against the movable plate.

[0009] Preferably, a limiting post is provided on one side of the movable plate, and a corresponding limiting hole is provided on the other side, so that adjacent movable plates can be fitted together.

[0010] Preferably, the head end of the limiting post is connected to a limiting ball, the inner end of the limiting hole is correspondingly provided with an enlarged hole, and the two sides of the movable plate are provided with plate sealing strips.

[0011] The beneficial effects of this invention are as follows: A movable transverse mechanism is provided on the side of the reaction tank, and an ultrasonic component is mounted on the movable transverse mechanism. The movable transverse mechanism drives the ultrasonic component to move laterally to different positions along the length of the side of the reaction tank, thereby generating ultrasonic vibrations within the reaction tank. This allows for flexible and adaptive adjustment of the ultrasonic component's position to accommodate different numbers and locations of photocatalytic reaction tubes. By introducing ultrasonic piezoelectric function, the ultrasonic vibration can effectively enhance the uniformity of catalyst dispersion, increase the contact probability between reactants and catalyst, and accelerate the reaction process. Simultaneously, it reduces catalyst agglomeration, extends catalyst lifespan, and improves the stability and repeatability of the photocatalytic reaction. Attached Figure Description

[0030] A multi-channel photocatalytic-ultrasonic piezoelectric coupling reaction device includes a cooling water circulation system and a photocatalytic reaction system. The cooling water circulation system includes a low-temperature constant temperature bath 1, an inlet pipe, and an outlet pipe. The photocatalytic reaction system includes a reaction water tank 3 and a photocatalytic reaction tube 5. The low-temperature constant temperature bath 1 is connected to an inlet 9 at one end of the reaction water tank 3 via the inlet pipe. The low-temperature constant temperature bath 1 is connected to an outlet 8 at the other end of the reaction water tank 3 via the outlet pipe. A movable transverse movement mechanism is provided on the side of the reaction water tank 3. An ultrasonic component 10 is provided on the movable transverse movement mechanism. The ultrasonic component 10 is moved laterally to different positions along the length of the side of the reaction water tank 3 by the movable transverse movement mechanism to generate ultrasonic vibration in the reaction water tank 3.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, this utility model is based on the existing multi-channel photocatalytic reaction device, including a cooling water circulation system and a photocatalytic reaction system. The cooling water circulation system includes a low-temperature constant temperature tank 1, an inlet pipe and an outlet pipe. The photocatalytic reaction system includes a reaction water tank 3 and a photocatalytic reaction tube 5. The low-temperature constant temperature tank 1 is connected to the inlet 9 at one end of the reaction water tank 3 through the inlet pipe. The low-temperature constant temperature tank 1 is connected to the outlet 8 at the other end of the reaction water tank 3 through the outlet pipe. When the water in the reaction water tank 3 is about to reach the critical water level, the water in the reaction water tank 3 flows back to the low-temperature constant temperature tank 1 through the two outlets 8 at the other end of the reaction water tank 3.

[0032] The photocatalytic reaction system includes a reaction tank 3, photocatalytic reaction tubes 5, an electronic ballast, ultraviolet lamps 6, slots 4, and a magnetic stirrer 2. The ultraviolet lamps are mounted on lamp holders 7. During the reaction, the reaction tank 3 is fixed to the magnetic stirrer 2. The three photocatalytic reaction tubes 5 are fitted with stainless steel slots 4 and fixed in positions where the magnetic stirrer 2 can operate. The four ultraviolet lamps 6 are mounted at both ends of the photocatalytic reaction tubes 5 through the lamp holders 7. The ultraviolet lamps 6 at both ends of the photocatalytic reaction tubes 5 ensure that the photocatalytic reaction in the photocatalytic reaction tubes 5 is illuminated evenly. The reaction tank 3 is a stainless steel tank with a length of 404mm, a width of 75mm, and a height of 190mm. The left and right ends of the reaction tank 3 are respectively provided with an outlet 8 and an inlet 9 with a diameter of 11mm, which effectively prevents the possibility of overflow after circulating water is introduced. The outlet 8 and the inlet 9 are connected to the inlet pipe and the outlet pipe by screws and are connected to the low-temperature constant temperature bath 1, so that the reaction tank 3 can maintain a constant temperature environment for the reaction at all times.

[0033] The photocatalytic reaction tube 5 in the photocatalytic reaction system is a flat-bottomed quartz photocatalytic tube with a length of 200mm, an outer diameter of 45mm, and a wall thickness of 2mm. The purpose of this is to ensure that the quartz tube has good light transmittance to ultraviolet light.

[0034] The ballast used is model HF-S218236TL-D II 220-240V 5060Hz; the UV lamp 6 is an 18W UV-C mercury lamp with a peak wavelength of 253.7nm. The compact size of the lamp allows for small system design and design flexibility. The TUV PL-L lamp can provide almost constant UV output throughout its entire lifespan.

[0035] Among them, such as Figure 2 and Figure 4 As shown, the top of the slot 4 is made of stainless steel with a width of 81mm, and the bottom of the slot is made of stainless steel with a width of 70mm. The slot 4 has an opening with an inner diameter of 46.1mm in the middle. The slot 4 has 20mm extension plates on both sides for fixing the slot to the reaction tank. The quartz tube, slot 4 and ultraviolet lamp 6 in the photocatalytic reaction system can be moved and disassembled at will. In the photocatalytic reaction laboratory, the number of quartz tubes required in the reaction system can be flexibly switched according to actual needs, which improves the flexibility of the device.

[0036] like Figure 2 and Figure 3 As shown, the lamp holder 7 is made of stainless steel, with a width of 81mm and an extension of 20mm downward on both sides. The top of the lamp holder 7 is equipped with a vertical stainless steel plate, on which the ultraviolet lamp 6 is mounted.

[0037] In summary, by setting up three photocatalytic reaction tubes 5, with ultraviolet lamps 6 at both ends of each photocatalytic reaction tube 5, the uniform illumination of each photocatalytic reaction tube 5 in the entire reaction system is ensured, greatly improving catalytic efficiency and throughput. The ultraviolet light source between two photocatalytic reaction tubes 5 can simultaneously illuminate two photocatalytic reaction tubes 5, improving the utilization rate of the light source. The ultraviolet lamps 6, photocatalytic reaction tubes 5, and slots 4 are all movable devices, allowing for easy switching of the number of reactors in the system, increasing the operability of the reactor.

[0038] In particular, such as Figure 7 , Figure 8 , Figure 9 As shown, a movable transverse mechanism is provided on the side of the reaction tank 3, and an ultrasonic component 10 is provided on the movable transverse mechanism, such as... Figure 6 As shown, the ultrasonic component 10 can adopt a conventional industrial-grade ultrasonic transducer with dimensions of 68mm wide and 66mm high, rated power of 100W, frequency of 28KHZ, capacitance of 6500Pf, control board operating frequency of 28-40KHZ, drive power of 50-100W, maximum output current of 0.5A, operating voltage of AC220V±10% 50HZ, dimensions of 120×75×42mm, and weight of 0.2KG.

[0039] The ultrasonic component 10 is moved laterally to different positions along the side length of the reaction tank 3 by a movable lateral movement mechanism. This generates ultrasonic vibrations within the reaction tank 3, allowing for flexible and adaptive adjustment of the ultrasonic component 10 to accommodate different numbers and positions of the photocatalytic reaction tubes 5. By introducing ultrasonic piezoelectric function, the ultrasonic vibration effectively enhances the uniformity of catalyst dispersion, increases the contact probability between reactants and catalyst, and accelerates the reaction process. Simultaneously, it reduces catalyst agglomeration, extends catalyst lifespan, and improves the stability and repeatability of the photocatalytic reaction.

[0040] In the embodiments of this utility model, optionally, such as Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12As shown, a rectangular opening 30 is provided on the side of the reaction tank 3. A horizontal sealing strip 31 and a vertical sealing strip 32 are respectively attached to the four outer sides of the opening 30. A sliding groove 33 is symmetrically provided on the upper and lower sides of the opening 30. The horizontal sealing strip 31 is located inside the sliding groove 33. The movable transverse mechanism includes multiple movable plates 11, at least one of which is equipped with an ultrasonic component 10. The ultrasonic component 10 slides and inserts along the sliding groove 33 through the top and bottom edges of the movable plates 11 until the opening 30 is closed by successive adjacent movable plates 11. Thus, the ultrasonic component 10 begins ultrasonic operation at the side of the reaction tank 3. The position of the ultrasonic component 10 is set by adjusting the position of the inserted movable plates 11. Temporary adjustments are possible when necessary. Figure 10 As shown, a new movable plate 11 is then inserted from the left or right side of the port 30 to push the ultrasonic component 10 to move laterally to different positions. Optionally, some of the movable plates 11 can be made of transparent material to be used as observation windows. Different movable plates 11 with different functions can be matched according to different experimental needs, and the different lateral positions of each movable plate 11 can be adjusted.

[0041] In the embodiments of this utility model, optionally, such as Figure 7 , Figure 8 As shown, the slide groove 33 is designed in an L-shape to facilitate the sliding insertion of the top and bottom edges of the movable plate 11 along the slide groove 33.

[0042] In the embodiments of this utility model, optionally, such as Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 As shown, the slide groove 33 is provided with locking bolts 34. The shank of the locking bolt 34 passes through the inner side of the slide groove 33, and multiple locking bolts 34 can be spaced apart along the length of the slide groove 33. After the positions of each movable plate 11 are adjusted laterally, the locking bolts 34 are tightened. Figure 12 As shown, the rod of the locking bolt 34 presses against the movable plate 11, so that the movable plate 11 presses tightly against the horizontal sealing strip 31 and the vertical sealing strip 32, thereby sealing the opening 30 tightly.

[0043] In the embodiments of this utility model, optionally, such as Figure 13As shown, a limiting post 12 is provided on one side of the movable plate 11, and a limiting hole 13 is correspondingly provided on the other side, so that adjacent movable plates 11 can be interlocked. The locking bolt 34 can be located at the middle position on the slide groove 33, and can be locked with only one locking bolt 34, so that each interlocked movable plate 11 tightly seals the opening 30. More preferably, the head end of the limiting post 12 is connected to a limiting ball 14, and the inner end of the limiting hole 13 is correspondingly provided with an enlarged hole 15. Plate sealing strips 16 are attached to both sides of the movable plate 11. The limiting ball 14 can be a hollow spherical structure and can be made of conventional elastic materials such as rubber. The size of the enlarged hole 15 is slightly larger than that of the limiting ball 14. 16 can use existing conventional components such as rubber sealing strips, similar to the transverse sealing strip 31 and vertical sealing strip 32. During use, adjacent movable plates 11 are sequentially pressed together, allowing each limiting post 12 to be inserted into the limiting hole 13. During insertion, the limiting ball 14 is compressed and contracts, sliding along the limiting hole 13 until the limiting post 12 is fully inserted. The limiting ball 14 then inserts into the enlarged hole 15 and elastically expands, thus locking itself within the enlarged hole 15 for limiting, ensuring a tight seal between adjacent plate sealing strips 16. Disassembly simply requires separating adjacent movable plates 11 sequentially to move the limiting ball 14 out of the limiting hole 13. This method is convenient to use, and the sealing effect is sufficient for reactive applications. Even better, such as... Figure 7 As shown, a liquid receiving tank 17 can also be provided under the bottom groove 33. The liquid receiving tank 17 is designed to be inclined to receive a small amount of leakage, and the leakage is then circulated into the low temperature constant temperature bath 1 for reuse.
