Description

Technical Field

[0001] This invention relates to the field of pollutant treatment technology, specifically to a photoelectrocatalytic degradation device for gaseous pollutants. Background Technology

[0002] Volatile organic compounds (VOCs) are important precursors to common air pollutants PM2.5 and ozone (O3), with large emissions and complex compositions, making them difficult to control. Existing VOCs treatment technologies are mainly divided into several categories: physical adsorption, combustion, absorption, and chemical scrubbing. All of these methods are used in production. Due to the complexity of VOCs composition, photocatalysis technology, which has good degradation effects and non-selective reactions to VOCs, has become a new research hotspot in the field of air purification. For example, patent application number 202310728079.9 discloses an adsorption-type photocatalytic degradation treatment device, relating to the technical field of waste gas treatment. The device includes a reaction chamber with an air inlet at one end and an air outlet at the other. At least one airflow distributor is installed inside the reaction chamber, and at least one activated carbon fiber roll is installed on the end face of the airflow distributor. One end of the roll is an open air inlet, and the other end is closed. Light sources are installed inside both the airflow distributor and the roll. A photocatalyst is attached to the roll, and electrodes are installed on the roll, capable of applying a fixed bias voltage.

[0003] When the above-mentioned photoelectrocatalytic degradation treatment device is used, three or more photoelectrocatalytic degradation treatment devices are connected in series to form a multi-stage treatment equipment to improve the treatment quality of gaseous pollutants. However, the photoelectrocatalytic degradation treatment device is generally composed of multiple rollers and multiple light sources. Although the multi-stage treatment equipment improves the treatment quality, the setting of multiple rollers and multiple light sources greatly increases the difficulty of dust cleaning and increases the labor cost of maintaining the photoelectrocatalytic degradation treatment device.

Both the transmission shaft 5 and the transmission shaft 4 are fixedly mounted with bevel gears, and the bevel gears on the transmission shaft 5 and the transmission shaft 4 mesh with each other. The outer side of the central transmission shaft 3 is fixedly mounted with a gear component 3, and a spoke bracket is fixedly mounted on the transmission shaft 3. The gear component 3 meshes with four gear components 1. A transmission ring is mounted on the spoke bracket. The outer ring and the inner ring of the transmission ring are both set as gear rings. The outer ring of the transmission ring meshes with four gear components 4, and the inner ring of the transmission ring meshes with four gear components 2.

[0010] Furthermore, the top end of the fourth drive shaft extends to the top of the processing box and is rotatably connected to the processing box.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example: Figures 1-12 As shown, the present invention provides a technical solution for a photoelectrocatalytic degradation device for gaseous pollutants, including a processing box 1. Four partition plates 5 are fixedly installed inside the processing box 1. A pollutant degradation structure is provided between each pair of adjacent partition plates 5. Each pollutant degradation structure includes four filter cylinders 7 and five linear light sources 19. Four linear light sources 19 are located between each pair of filter cylinders 7, and another linear light source 19 is located at the center of each of the four filter cylinders 7. A linear light source 11 is provided inside each of the four filter cylinders 7. A U-shaped frame 45 is fixedly installed on the outside of each of the four filter cylinders 7, and a sponge block 46 is fixedly installed on the outside of the U-shaped frame 45. A gear transmission assembly is provided on one side of each of the three pollutant degradation structures. Each of the three gear transmission assemblies includes a transmission shaft 22. A sampling assembly is provided between the three transmission shafts 22. A ash discharge trough 32, an arc-shaped plate 33, and a ash discharge trough 36 are provided on one side of the bottom of each of the three pollutant degradation structures.

[0034] Specifically, such as Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, an air inlet bend 3 is fixedly installed at the air inlet end of the treatment box 1. The air inlet bend 3 is used for gaseous pollutants to enter the interior of the treatment box 1. An exhaust pipe 4 is fixedly installed at the air outlet end of the treatment box 1. The exhaust pipe 4 discharges the degraded and purified gas. A support frame 2 is fixedly installed at the bottom of the treatment box 1. Under the support of the support frame 2, the treatment box 1 is tilted. The end of the treatment box 1 where the air inlet bend 3 is installed faces downward and the end of the treatment box 1 where the exhaust pipe 4 is installed faces upward.

[0035] Four partition plates 5 are fixedly installed inside the treatment box 1, dividing the interior of the treatment box 1 into three degradation spaces. Each degradation space is equipped with a pollutant degradation structure. Four diversion channels 6 are opened on one side of each of the four partition plates 5. The four filter cylinders 7 in the pollutant degradation structure are all located on the side of the partition plate 5 away from the air inlet bend 3. The end of the filter cylinder 7 facing the air inlet bend 3 is the open end, and the end of the filter cylinder 7 away from the air inlet bend 3 is the closed end. The gas entering the treatment box 1 through the air inlet bend 3 first enters the filter cylinder 7 through the diversion channel 6. After the gaseous pollutants are filtered and the particulate matter is intercepted by the filter cylinder 7, they move to the outside of the filter cylinder 7 and enter the interior of the treatment box 1.

[0036] Furthermore, a photocatalyst is attached to the filter cartridge 7, and a metal negative electrode 8 and a metal positive electrode 9 are fixedly installed on the outside of the filter cartridge 7. The metal negative electrode 8 and the metal positive electrode 9 are comb-shaped after being laid flat, and the comb teeth of the metal negative electrode 8 and the metal positive electrode 9 are arranged in an alternating manner. The working metal negative electrode 8 and the metal positive electrode 9 generate a coupled electric field covering the outside of the filter cartridge 7. Linear light source 11 is set inside each of the four filter cartridges 7. Four of the five linear light sources 219 are distributed in a ring between each pair of the four filter cartridges 7, and the other linear light source 219 is set in the center of the four filter cartridges 7. The four linear light sources 11 and the five linear light sources 219 provide sufficient light for the airflow to ensure that the photocatalyst fully reacts with the gaseous pollutants and degrades them.

[0037] After the gaseous pollutants enter the treatment chamber 1 through the inlet bend 3, they enter the four filter cartridges 7 in the first degradation space under the action of the partition plate 5. During the process of the gaseous pollutants passing through the walls of the filter cartridges 7 into the treatment chamber 1, the filter cartridges 7, made of activated carbon fiber, play an adsorption role, which makes the waste gas more fully contacted with the photocatalyst. The gaseous pollutants come into contact with the photocatalyst attached to the filter cartridges 7. Under the action of four linear light sources 11 and five linear light sources 19, the gaseous pollutants react efficiently with the photocatalyst during the flow process. Moreover, the gaseous pollutants pass through the coupled electric field covering the outside of the filter cartridges 7. The coupled electric field strongly inhibits the recombination of photogenerated electrons and holes generated by ultraviolet light, improves photocatalytic activity and accelerates the reaction rate.

[0038] After being degraded by the pollutant degradation structure inside the first degradation space, the gaseous pollutants sequentially enter the second and third degradation spaces. After being treated by the three pollutant degradation structures, the gaseous pollutants are discharged through the exhaust pipe 4. The gaseous pollutants are treated multiple times to ensure the quality of gaseous pollutant treatment.

[0039] Specifically, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the open end of the filter cylinder 7 is rotatably connected to the partition plate 5, allowing the filter cylinder 7 to rotate. A mounting bracket 12 is rotatably connected to one end of the linear light source 11, and the mounting bracket 12 is fixedly installed inside the partition plate 5. A drive shaft 13 is fixedly installed at the other end of the linear light source 11. One end of the drive shaft 13 passes through the filter cylinder 7 and is rotatably connected to it, allowing the linear light source 11 to rotate inside the filter cylinder 7. A gear component 14 is fixedly installed on the outside of the drive shaft 13, and a gear component 10 is fixedly installed on the outside of the filter cylinder 7. The drive shaft 13 passes through the gear component 10, and the rotation of the drive shaft 13 will not affect the operation of the gear component 10.

[0040] Furthermore, one end of each of the five linear light sources 219 is rotatably connected to the adjacent partition plate 5. The five drive shafts 320 in the gear transmission assembly are respectively fixedly connected to the five linear light sources 219. Gear components 421 are fixedly installed on the four outer drive shafts 320, and a drive shaft 517 is fixedly installed on one end of the central drive shaft 320. A gear component 318 and a spoke support 16 are fixedly installed on the central drive shaft 320. The gear component 318 meshes with four gear components 10 arranged in a ring. When the gear component 318 rotates, the four gear components 10 rotate, and the filter fixedly connected to the gear components 10... The cylinder 7 rotates; a transmission ring 15 is fixedly installed on the spoke support 16. The outer and inner rings of the transmission ring 15 are both set as gear rings 44. The outer ring of the transmission ring 15 meshes with four gear components 21, and the inner ring of the transmission ring 15 meshes with four gear components 14. When the transmission ring 15 rotates, the four gear components 14 and four gear components 21 rotate, and the gear component 18 drives the linear light source 19 in the middle to rotate through the transmission shaft 20 in the middle. At this time, the five linear light sources 19 and four linear light sources 11 rotate. Due to the characteristics of gear transmission, the linear light source 11 and the filter cylinder 7 rotate in different directions and at different speeds.

[0041] A bevel gear 23 is fixedly installed on the outer side of both the fifth drive shaft 17 and the fourth drive shaft 22, and the two bevel gears 23 mesh with each other; the top end of the fourth drive shaft 22 extends to the top of the processing box 1 and is rotatably connected to the processing box 1; a gearbox 25 is fixedly installed on the top of the processing box 1; the three fourth drive shafts 22 are fixedly connected to the three output ends of the gearbox 25 respectively; the drive motor 26, which is fixedly connected to the input end of the gearbox 25, is fixedly installed on the top of the processing box 1 and controls the operation of the first air pump 27; the gearbox 25 drives the three fourth drive shafts 22 to rotate.

[0042] In summary, after the drive motor 26 is activated, under the transmission of the three gear transmission components, the four filter cartridges 7, the four linear light sources 11, and the five linear light sources 29 in the three pollutant degradation structures all rotate.

[0043] Specifically, such as Figure 2 , Figure 3 and Figure 8 As shown, the sampling assembly consists of a vacuum pump 27 fixedly installed on the top of the processing box 1, a return pipe 47 fixedly installed between the outlet end of the vacuum pump 27 and the inlet bend 3, a guide pipe 31 fixedly installed on the inlet end of the vacuum pump 27, and three three-way valves 29 fixedly installed on the guide pipe 31. A guide box 28 is fixedly installed on one side of the three-way valve 29. The guide box 28 is fixedly installed on the top of the processing box 1 and movably sleeved on the outside of the drive shaft 22. Therefore, the rotation of the drive shaft 22 will not be affected by the guide box 28. A sampling tube 30 is fixedly installed on the normally closed end of the three-way valve 29.

[0044] Furthermore, the hollow interior of the drive shaft 22 forms an air guide channel 24, with both ends of the air guide channel 24 connected to the interior of the air guide box 28 and the interior of the processing box 1, respectively, enabling the drive motor 26 to draw air from the interior of the processing box 1 through the air guide pipe 31, the three-way valve 29, the air guide box 28, and the air guide channel 24.

[0045] Specifically, such as Figure 2 , Figure 3 and Figure 8 As shown, both ash discharge trough 1 32 and ash discharge trough 2 36 are located on the processing box 1. An arc-shaped plate 33 is inserted inside the ash discharge trough 1 32, which seals the inside of the ash discharge trough 1 32. When the position of the arc-shaped plate 33 remains unchanged, the gas inside the processing box 1 will not leak through the ash discharge trough 1 32. A mounting bracket 2 34 is fixedly installed between the three arc-shaped plates 33. A pneumatic cylinder 35 is fixedly installed on one side of the mounting bracket 2 34 and embedded in one side of the processing box 1. By controlling the operation of the pneumatic cylinder 35, the three arc-shaped plates 33 can be controlled to move inside the ash discharge trough 1 32 through the mounting bracket 2 34.

[0046] A manifold 37 is fixedly installed on one side of the treatment box 1. The two ends of the ash discharge trough 36 are connected to the inside of the manifold 37 and the adjacent arc plate 33, respectively. A filter screen 38 that serves as a filter is fixedly installed on the top of the manifold 37. A flared pipe 39 set on the top of the filter screen 38 is fixedly connected to the manifold 37. An air pump 40 is fixedly installed between two mounting brackets 41 fixedly installed on one side of the treatment box 1. The air inlet end of the air pump 40 is fixedly connected to the flared pipe 39. An external threaded part 42 is fixedly installed at the bottom of the manifold 37. An internal threaded part 43 is fitted on the outer thread of the external threaded part 42.

[0047] The working principle of the photoelectrocatalytic degradation device in this embodiment is as follows:

[0048] During the treatment of gaseous pollutants in the photoelectrocatalytic degradation device, the sampling pump 27 in the control sampling component operates. The gas guide pipe 31 fixedly installed at the inlet end of the gas pump 27 is fixedly connected to the normally open end of the three-way valve 29. The operating gas pump 27 draws air from inside the treatment box 1 through the gas guide pipe 31, the three-way valve 29, the gas guide box 28, and the gas guide channels 24 opened on the three drive shafts 22. The three drive shafts 22 are respectively set at the ends of the three pollutant degradation structures. A return pipe 47 is fixedly installed between the outlet end of the gas pump 27 and the inlet bend 3. After the residual gas inside the gas guide channel 24 is transported and discharged for a period of time, the gas guide channel 24 and the gas guide box 28 are filled with the pollutant degradation structures. After the gas has been degraded, the exhaust pump 27 is stopped, and the normally closed end of the three-way valve 29 is opened. At this time, the gas degraded by the pollutant degradation structure is discharged through the sampling tube 30 and enters the sampling system that the staff has set up in advance at one end of the sampling tube 30. After a period of time, the normally open end of the three-way valve 29 is opened, and the sampling work from the end of the pollutant degradation structure can be completed. Sampling can be carried out from the end of three pollutant degradation structures at one time. The staff can judge the working status of the corresponding pollutant degradation structure based on the processing status of the samples at the corresponding locations. At the same time, the staff can locate the pollutant degradation structures with reduced working efficiency or even damage, so as to facilitate the arrangement of maintenance.

[0049] After the photoelectrocatalytic degradation device has been working to treat gaseous pollutants for a period of time, the gas supply to the inlet bend 3 is stopped, and the drive motor 26 is controlled to work. Under the transmission of the gearbox 25 and three gear transmission components, the four filter cartridges 7, the four linear light sources 11, and the five linear light sources 29 in each pollutant degradation structure all rotate. Because the gear components 10, 24, 318, and 421 in the gear transmission components are of different sizes, under the gear transmission characteristics, the multiple linear light sources 11 and the multiple filter cartridges 7 rotate in different directions and at different speeds. The rotating linear light sources 29, filter cartridges 7, and linear light sources 11 throw off most of the dust attached to the outside; and U-shaped frames 45 are fixedly installed on the outside of each of the four filter cartridges 7. A sponge block 46 is fixedly installed on the outside of the filter cylinder 7. The filter cylinder 7 drives the U-shaped frame 45 and the sponge block 46 to rotate. The rotation trajectory of the sponge block 46 is tangent to the rotation trajectory of the four linear light sources 19 on the outer layer. The rotation speed of the filter cylinder 7 is different from that of the linear light sources 19. Therefore, the rotating sponge block 46 has the effect of cleaning the surface of the linear light sources 19, ensuring that the linear light sources 19 provide sufficient light for the reaction of gaseous pollutants and photocatalysts inside the treatment box 1. Under the support of the support frame 2 fixedly installed at the bottom of the treatment box 1, the treatment box 1 is tilted. The end of the treatment box 1 with the intake bend 3 is facing down, the end of the treatment box 1 with the exhaust pipe 4 is facing up, and the open end of the filter cylinder 7 is facing down. Dust and impurities inside the filter cylinder 7 leave the inside of the filter cylinder 7 under the action of gravity.

[0050] By simply controlling the drive motor 26, the three pollutant degradation structures can be cleaned under the transmission of three gear transmission components, reducing the impurities attached to the outside of the four filter cartridges 7, the four linear light sources 11 and the five linear light sources 2 19, and reducing the labor cost required for the maintenance of the photoelectrocatalytic degradation device.

[0051] During the operation of the air pump 27, the pneumatic cylinder 35 is activated, causing the three arc-shaped plates 33 to move. This allows the ash discharge trough 36 to connect with the interior of the processing box 1 via the ash discharge trough 32. The partition plate 5, which houses the filter cartridge 7, is positioned on one side of the top of the adjacent ash discharge trough 32. The ash discharge trough 32 is connected to the spaces on both sides of the partition plate 5. Dust and impurities leaving the filter cartridge 7, as well as impurities leaving the outside of the linear light source 19 and the filter cartridge 7, can enter the ash discharge trough 32. The drive motor 26 operates before the pneumatic cylinder 35, and one of the rotating sponge blocks 46 agitates the bottom of the processing box 1, raising the dust and impurities at the bottom of the processing box 1. This process effectively removes the dust and impurities from the processing box 1. After the air pump 40 operates, it draws air from inside the treatment box 1 through the flared pipe 39, the manifold box 37, three ash discharge troughs 36 and 32. The negative pressure inside the ash discharge trough 32 draws the dust out of the treatment box 1. The filter screen 38 filters and traps the dust and impurities entering the air pump 40, keeping them inside the manifold box 37. An external threaded part 42 is fixedly installed at the bottom of the manifold box 37. An internal threaded part 43 with an external threaded part 42 is set at the bottom of the filter screen 38. Most of the dust and impurities trapped by the filter screen 38 fall into the internal threaded part 43. The dust and impurities can be collected and treated by rotating the internal threaded part 43 after the air pump 40 stops working.

[0052] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
