Description

Technical Field

[0001] The present invention relates to the technical field of photocatalytic reactors, and particularly to a normal-temperature photocatalytic reactor and method for synthesizing polycyclic compounds. Background Technique

[0002] Photocatalytic reaction refers to the process of accelerating the reaction rate by a photocatalyst absorbing light energy and reducing the activation energy of a chemical reaction. The core of this reaction lies in that the photocatalyst can absorb the photon energy of a specific wavelength, excite molecules to a high-energy state, and then initiate a chemical reaction. The principle of photocatalytic reaction is mainly based on the light absorption characteristics of semiconductors. When light with energy greater than or equal to the band gap of the semiconductor irradiates the surface of the catalyst, electrons in the valence band are excited and jump to the conduction band, while holes are left in the valence band, forming electron-hole pairs. This process triggers a series of redox reactions, specifically including: Photo-generated electrons: Participate in reduction reactions (such as decomposing organic substances and reducing heavy metal ions). Photo-generated holes: Participate in oxidation reactions (such as decomposing pollutants and sterilizing).

[0003] After retrieval, a photocatalytic reactor is disclosed in Chinese Patent Publication No. CN106669412A. The photocatalytic reactor includes a housing, an ultraviolet lamp tube, and a photocatalytic component. The housing is provided with an inlet and an outlet communicating with the accommodation space; the ultraviolet lamp tube is accommodated in the accommodation space; the photocatalytic component is accommodated in the accommodation space. The photocatalytic component is a hollow column structure with both ends open and a photocatalyst attached to the inner surface. The two ends of the photocatalytic component are respectively connected to the inlet and the outlet of the housing. The inner surface of the photocatalytic component has a plurality of V-shaped grooves, and the angle of each V-shaped groove does not exceed 20°, and the depth of each V-shaped groove is at least 2 cm; wherein, the ultraviolet lamp tube is fixedly arranged through the photocatalytic component, and the extending direction of the ultraviolet lamp tube is parallel to the extending direction of the photocatalytic component.

[0004] When the photocatalytic reactor in the above technical solution performs a photocatalytic reaction, the total amount of the photocatalyst is fixed. This way, when a continuous reaction is carried out, the amount of the photocatalyst participating in the catalytic reaction decreases, resulting in a decrease in the efficiency of the catalytic reaction. Therefore, a photocatalytic reactor that can adapt to continuous reactions is needed. Summary of the Invention

[0005] The purpose of the present invention is to provide a normal-temperature photocatalytic reactor and method for synthesizing polycyclic compounds to solve the problems raised in the above background technique.

[0013] Furthermore, an arc-shaped opening is provided on the side of the storage chamber facing the unwinding roller, and the arc-shaped opening is adapted to the contour of the unwinding roller.

[0014] Furthermore, a push plate is snap-fitted inside the storage chamber. The push plate slides freely inside the storage chamber. The push plate is fixedly connected with at least one guide post. A nut is fixedly sleeved at the end of the guide post far away from the storage chamber. A tension spring is wound around the periphery of the guide post, and both ends of the tension spring are fixedly connected to the outer wall of the nut and the outer wall of the storage chamber respectively, and impart potential energy to the push plate to move towards the unwinding roller.

[0015] Furthermore, the winding assembly includes a plurality of driven guide rollers whose two ends are respectively rotatably connected to the two partitions. The driven guide rollers are evenly distributed inside the reaction chamber. Two guide rollers are rotatably connected to the side of the two partitions close to the installation chamber. The adhesive film is unrolled from the unwinding roller, bypasses one of the guide rollers, a plurality of the driven guide rollers and the other guide roller in sequence, and is wound onto the winding roller.

[0016] Furthermore, belt pulleys are respectively installed at the ends of the winding roller and the unwinding roller. The two belt pulleys are drivingly connected by a V-belt, and one of the belt pulleys is driven to rotate by an external motor.

[0017] Further, a vibration material component is provided on the partition board. The vibration material component includes a sliding block snap-fitted and installed in a sliding cavity opened on the end face of the partition board. The sliding block freely slides along the radial direction of the partition board in the sliding cavity. The two ends of the driven guide roller are correspondingly rotatably connected to the sliding blocks on the two partition boards. The sliding block is driven to move by a driving unit provided on the partition board.

[0018] Further, the driving unit includes an ear block fixedly connected to the end face of the partition board. A sliding column is fixedly connected to the sliding block. The sliding column slidably penetrates through the ear block, and a sliding pin is fixedly connected to the end of the sliding column that penetrates out of the ear block. A rotating part is coaxially rotatably connected to the end face of the partition board. An annular groove for the sliding column to freely pass through is opened on the periphery of the rotating part. A special-shaped sliding groove for the sliding pin to be inserted is opened on the end face of the rotating part;

[0019] The special-shaped sliding groove includes a straight groove and an inclined groove connected end to end. The length direction of the straight groove is perpendicular to the axial direction of the rotating part. One end of the inclined groove far from the straight groove extends obliquely towards the outer side of the periphery of the rotating part. A spring is wound around the periphery of the sliding column. The two ends of the elastic force direction of the spring elastically abut against the sliding block and the ear block respectively;

[0020] The reaction chamber is provided with a rotating structure for driving the rotating part to rotate.

[0021] Further, the rotating structure includes a second cylinder installed on the outer wall of the reaction chamber. The second cylinder is drivingly connected with a rack column. The rack column slidably penetrates through the reaction chamber. An annular gear part is coaxially fixedly connected to the end face of the rotating part. The annular gear part meshes with the rack column.

[0022] A method for synthesizing polycyclic compounds by photocatalysis at room temperature is applied to the photocatalytic reactor as described above, and includes:

[0023] The reactants of the polycyclic compound enter the reaction chamber from the inlet and enter between the two partition boards through the fluid channel openings on the partition board. Under the action of ultraviolet light emitted by the ultraviolet lamp, the photocatalyst powder adhered to the surface of the adhesive film undergoes a catalytic reaction with the reactants of the polycyclic compound to complete one catalytic reaction;

[0024] During continuous reaction, after a single catalytic reaction is completed, the winding component unwinds the adhesive film, so that the adhesive film is unwound from the unwinding roller and finally wound on the winding roller, so as to replace the adhesive film in the reaction chamber again;

[0025] When the adhesive film is unwound, the photocatalyst coating component smears the photocatalyst powder on the adhesive layer surface of the adhesive film, so that a layer of photocatalyst powder adheres to the adhesive layer of the adhesive film, and then the photocatalyst powder on the surface of the adhesive film in the reaction chamber participates in the next photocatalytic reaction.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. In the present invention, the adhesive film is unrolled through the winding assembly, so that the adhesive film in the reaction chamber can be replaced for continuous reaction, avoiding the reduction of the amount of photocatalyst participating in the reaction on the adhesive film and affecting the photocatalytic reaction efficiency. In addition, through the photocatalyst coating assembly, the photocatalyst powder can be coated on the adhesive layer surface of the adhesive film, thus realizing the replenishment of the photocatalyst. In addition, the winding roller winds and recovers the adhesive film attached with the photocatalyst after the reaction for subsequent recovery of the photocatalyst;

[0028] 2. In the present invention, under the action of the elastic potential energy of the tension spring, the push plate has the potential energy to move towards the unwinding roller, so that the push plate can drive the photocatalyst powder in the storage bin towards the direction of the unwinding roller, enabling the photocatalyst powder to be coated on the adhesive film surface of the unwinding roller;

[0029] 3. In the present invention, by quickly sliding the sliding block towards the outer side of the periphery of the partition plate, the driven guide roller quickly tensions the adhesive film, thereby generating vibration on the adhesive film and rapidly increasing the surface tension of the adhesive film. As a result, the reactants of the polycyclic aromatic compounds stuck in the gaps of the photocatalyst powder can be shaken off when the adhesive film is quickly tensioned, avoiding the reactants being stuck in the gaps of the photocatalyst powder and being wound onto the winding roller.

Detailed implementation manners

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] Please refer to Figures 1 - 12, the present invention provides a technical solution: a room-temperature photocatalytic reactor for synthesizing polycyclic compounds, comprising a reaction chamber 2 with both ends open and an inlet 1 and an outlet 6 installed respectively. The inlet 1 is connected to an external conveying system, which conveys the reactants of the polycyclic compounds to the inlet 1. Two partitions 10 are coaxially and fixedly connected to the inner cavity of the reaction chamber 2, and the two partitions 10 are respectively located at the axial two ends of the reaction chamber 2. In addition, the partitions 10 are provided with a plurality of fluid passage openings 12, and an ultraviolet lamp 17 is commonly installed on the end faces of the two partitions 10, and the ultraviolet lamp 17 is powered by an external power supply;

[0045] On the upper side of the periphery of the reaction chamber 2, there is a fixedly connected installation chamber 3. A winding roller 15 and an unwinding roller 14 are rotatably connected in the installation chamber 3. The unwinding roller 14 and the winding roller 15 are symmetrically arranged along the center line of the installation chamber 3. Belt pulleys are installed at the ends of the winding roller 15 and the unwinding roller 14 respectively, and the two belt pulleys are connected by a triangular belt in transmission. And one of the belt pulleys is driven to rotate by an external motor. In this way, when an external motor drives one belt pulley to rotate, it can drive the other belt pulley to rotate through the transmission of the triangular belt, so that the winding roller 15 and the unwinding roller 14 can rotate synchronously. One side outer wall of the installation chamber 3 is integrally formed or connected by welding with a fixed chamber 32, and the inner cavity of the fixed chamber 32 is communicated with the inner cavity of the installation chamber 3;

[0046] A storage chamber 5 is snap-fitted and installed in the fixed chamber 32. The storage chamber 5 can freely slide horizontally in the fixed chamber 32 in the direction towards the unwinding roller 14. In addition, one side of the storage chamber 5 facing the unwinding roller 14 is open, and it stores photocatalyst powder (or fine particles) therein. A first cylinder 4 is horizontally installed on the side wall of the fixed chamber 32. The cylinder rod of the first cylinder 4 slidably penetrates into the fixed chamber 32 and is fixedly connected to the outer wall of the storage chamber 5. Thus, when the cylinder rod of the first cylinder 4 expands and contracts, it can drive the storage chamber 5 to slide horizontally in the fixed chamber 32. In addition, an arc-shaped opening is provided on the side of the storage chamber 5 facing the unwinding roller 14, and the arc-shaped opening is adapted to the contour of the unwinding roller 14, that is, the arc-shaped opening of the storage chamber 5 can be stuck on the periphery of the unwinding roller 14;

[0047] A plurality of sliding cavities 26 distributed in a ring shape are formed at the end faces of the two partition plates 10. A sliding block 9 is snap-fitted and installed in each sliding cavity 26. The sliding block 9 can freely slide radially along the partition plate 10 in the sliding cavity 26. In addition, a bearing is installed on the sliding block 9. The bearings of the two corresponding sliding blocks 9 on the two partition plates 10 are jointly inserted with a driven guide roller 19. Two guide rollers 18 are jointly rotatably connected to the upper sides of the two partition plates 10 through bearings. An adhesive film 13 is wound on the unwinding roller 14. The adhesive layer side of the adhesive film 13 corresponds to the storage bin 5. A film passing opening 31 for the free passage of the adhesive film 13 is formed in the outer wall of the reaction chamber 2. After the adhesive film 13 on the unwinding roller 14 is unwound from the unwinding roller 14, it passes through the film passing opening 31, then bypasses the guide roller 18 below the unwinding roller 14, then sequentially bypasses all the driven guide rollers 19, then bypasses a guide roller 18 below the winding roller 15, and then passes out through the film passing opening 31 and is wound on the winding roller 15. The driven guide rollers 19 are evenly distributed in the reaction chamber 2, so that the adhesive film 13 in the reaction chamber 2 is distributed in a ring shape and encloses a catalytic reaction space with the two partition plates 10;

[0048] A push plate 27 is snap-fitted and installed in the storage bin 5. The push plate 27 can freely slide in the storage bin 5. At least one guide post 30 is fixedly connected to the push plate 27. A nut 28 is fixedly sleeved at the end of the guide post 30 far away from the storage bin 5. A tension spring 29 is wound around the periphery of the guide post 30. The two ends of the tension spring 29 are respectively fixedly connected to the outer wall of the nut 28 and the outer wall of the storage bin 5, and endow the push plate 27 with the potential energy to move towards the unwinding roller 14. Under the action of the elastic potential energy of the tension spring 29 on the push plate 27, the push plate 27 has the potential energy to move towards the unwinding roller 14, so that the push plate 27 can drive the photocatalyst powder in the storage bin 5 towards the unwinding roller 14, so that the photocatalyst powder can be coated on the adhesive layer surface of the adhesive film 13 on the unwinding roller 14, and then the photocatalyst powder is coated on the surface of the adhesive film 13;

[0049] A plurality of ear blocks 20 corresponding to the positions of the sliding blocks 9 are fixedly connected to the end faces of the partition plates 10. A sliding column 22 is fixedly connected to the sliding block 9. The sliding column 22 slidably penetrates through the ear block 20, and a sliding pin 25 is fixedly connected to the end of the sliding column 22 that penetrates out of the ear block 20. A rotating part 11 is coaxially rotatably connected to the end face of the partition plate 10. An annular groove for the free passage of the sliding column 22 is formed on the periphery of the rotating part 11. A special-shaped sliding groove for inserting the sliding pin 25 is formed on the end face of the rotating part 11. The special-shaped sliding groove includes a straight groove 24 and an inclined groove 23 connected end to end. The length direction of the straight groove 24 is perpendicular to the axial direction of the rotating part 11. The end of the inclined groove 23 far away from the straight groove 24 extends obliquely towards the outer side of the periphery of the rotating part 11. A spring 21 is wound around the periphery of the sliding column 22. The two ends of the elastic force direction of the spring 21 elastically abut against the sliding block 9 and the ear block 20 respectively;

[0050] A second cylinder 7 is horizontally installed on the outer wall of the reaction chamber 2. The second cylinder 7 is drivingly connected to a rack column 8. The rack column 8 is slidably disposed through the reaction chamber 2. An annular gear portion 16 is coaxially and fixedly connected to the end face of the rotating portion 11. The annular gear portion 16 meshes with the rack column 8. The cylinder rod of the second cylinder 7 drives the rack column 8 to move horizontally, so that the rack column 8 meshes and drives with the annular gear portion 16, and further enables the annular gear portion 16 to drive the rotating portion 11 to rotate slightly. When the rotating portion 11 rotates, the sliding pin 25 slides in the special-shaped chute. When the sliding pin 25 slides from the straight groove 24 into the inclined groove 23, under the elastic abutting force of the spring 21, the sliding block 9 will quickly move towards the outer side of the periphery of the partition plate 10, so that the driven guide roller 19 quickly tensions the adhesive film 13, and a vibration force is generated on the surface of the adhesive film 13. Under the action of the vibration force, the reactants of the polycyclic aromatic compounds stuck in the gaps of the photocatalyst powder can be shaken off.

[0051] The working principle of the present invention:

[0052] The external conveying system conveys the reactants of the polycyclic aromatic compounds to the inlet 1, and then enters the reaction chamber 2 from the inlet 1. Subsequently, it enters the catalytic reaction space enclosed by the adhesive film 13 and the two partition plates 10 through the fluid channel opening 12 on the partition plate 10. The ultraviolet light emitted by the ultraviolet lamp 17 generates a photocatalytic reaction on the photocatalyst powder on the surface of the adhesive film 13, and further enables the photocatalyst powder after the photocatalytic reaction to react with the reactants. After a certain period of time, the reactants are discharged from the outlet 6 to complete a photocatalytic reaction.

[0053] In addition, when the total amount of reactants in the catalytic reaction space is relatively large, some reactants may be stuck between the gaps of the photocatalyst powder. Therefore, after the photocatalytic reaction is completed, the second cylinder 7 is first started. The cylinder rod of the second cylinder 7 extends, so that the rack column 8 meshes with the annular gear portion 16 on the rotating portion 11. During the meshing transmission process, the rotating portion 11 will be driven to rotate. When the rotating portion 11 rotates, the sliding pin 25 slides from the straight groove 24 into the inclined groove 23. Under the elastic abutting force of the spring 21, the sliding block 9 will quickly move towards the outer side of the periphery of the partition plate 10, so that the driven guide roller 19 generates a rapid tensioning force on the adhesive film 13. Under the action of the tensioning force, a vibration is generated on the surface of the adhesive film 13, and then the reactants stuck in the gaps of the photocatalyst powder are shaken off.

[0054] When carrying out a continuous reaction, first start the external motor. The external motor drives the pulley to rotate. Then, through the transmission of the V-belt, it can drive another pulley to rotate, so that the winding roller 15 and the unwinding roller 14 can rotate synchronously. The winding roller 15 starts to wind the adhesive film 13 in the reaction chamber 2. At the same time, the unwinding roller 14 unwinds, so that the adhesive film 13 can be replaced. During the winding process of the adhesive film 13, the piston rod of the first cylinder 4 slowly extends slightly, so that the piston rod of the first cylinder 4 drives the storage bin 5 to slide in the fixed bin 32, making the storage bin 5 move towards the unwinding roller 14. At the same time, under the pulling force of the tension spring 29 on the nut 28, the guide post 30 will drive the push plate 27 to move towards the unwinding roller 14, so that the push plate 27 can drive the photocatalyst powder in the storage bin 5 towards the unwinding roller 14, and then the photocatalyst powder can be coated on the adhesive layer surface of the adhesive film 13, so that the adhesive layer surface of the adhesive film 13 is coated with photocatalyst powder. Then, the adhesive film 13 coated with photocatalyst powder is unrolled into the reaction chamber 2, so that the adhesive film 13 is distributed in a ring shape in the reaction chamber 2, and then the next photocatalytic reaction can be carried out.

A method for synthesizing polycyclic compounds by a room-temperature photocatalytic reaction, which is applied to the photocatalytic reactor described in any one of claims 1 to 9, and is characterized in that, Comprising: The reactant of the polycyclic compound enters the reaction chamber (2) from the inlet (1), and enters between the two partition plates (10) through the fluid channel opening (12) on the partition plate (10). Under the action of the ultraviolet light emitted by the ultraviolet lamp (17), the photocatalyst powder adhered to the surface of the adhesive film (13) undergoes a catalytic reaction with the reactant of the polycyclic compound to complete a catalytic reaction. During continuous reaction, after a single catalytic reaction is completed, the winding assembly unwinds the adhesive film (13), so that the adhesive film (13) is unwound from the unwinding roller (14) and finally wound on the winding roller (15), so as to replace the adhesive film (13) in the reaction chamber (2) again. When the adhesive film (13) is unwound, the photocatalyst coating assembly smears the photocatalyst powder on the adhesive layer surface of the adhesive film (13), so that a layer of photocatalyst powder adheres to the adhesive layer of the adhesive film (13), and then the photocatalyst powder on the surface of the adhesive film (13) in the reaction chamber (2) participates in the next photocatalytic reaction.
