DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0027] In one embodiment, see Figure 1 、 Figure 2 、 Figure 3 and Figure 7, an industrial waste gas desulfurization, denitrification and dust removal equipment, including a treatment box 1, a filter screen plate 10 is provided inside the treatment box 1, the filter screen plate 10 is in a bamboo hat structure, the side wall of the filter screen plate 10 is slidably connected to the inner wall of the treatment box 1, the filter screen plate 10 is connected to a vibration mechanism 3, the vibration mechanism 3 is used to drive the filter screen plate 10 to vibrate up and down, a partition 11 is provided below the filter screen plate 10, the partition 11 is fixedly connected to the inner wall of the treatment box 1, an elastic filter cloth 12 is fixedly provided at the bottom of the partition 11, the bottom of the elastic filter cloth 12 is fixedly connected to the bottom of the treatment box 1, the elastic filter cloth 12 is connected end to end in a rectangular shape, and a support rod 13 is provided on the inside of the elastic filter cloth 12 in a rectangular distribution to support the elastic filter cloth 12, the elastic filter cloth 12 is provided with a support rod 13 in a rectangular distribution to support the elastic filter cloth 12, A through hole 16 is provided on the inner side of the filter cloth 12 and the interior of the partition 11, and a supporting mechanism 5 is provided on the outer side of the elastic filter cloth 12. The supporting mechanism 5 is used to support the elastic filter cloth 12, so that the elastic filter cloth 12 is deformed. A spraying mechanism 2 is provided inside the elastic filter cloth 12. The spraying mechanism 2 is used to spray the reaction liquid onto the inner side of the elastic filter cloth 12. An air inlet 7 is provided on the top of the processing box 1, and an air outlet 9 is provided below the partition 11 and on the side wall of the processing box 1. A rotating rod 14 passes through the top of the processing box 1, and a motor 6 is connected to the upper end of the rotating rod 14. A fixed plate 15 is fixed to the lower end of the rotating rod 14, and a cleaning mechanism 4 is provided on the fixed plate 15. The cleaning mechanism 4 is used to clean particulate impurities on the surface of the filter mesh plate 10.

[0028] In this embodiment, when the industrial waste gas is subjected to desulfurization, denitrification and dust removal treatment, the waste gas enters the interior of the treatment box 1 through the air inlet 7 on the top of the treatment box 1, and the waste gas is filtered by the filter plate 10 inside the treatment box 1, thereby removing particulate impurities in the waste gas. After passing through the filter plate 10, the waste gas enters the inside of the elastic filter cloth 12 through the through hole 16. At this time, the reaction liquid is sprayed to the inside of the elastic filter cloth 12 through the spray mechanism 2. The reaction liquid reacts chemically with the harmful substances in the waste gas, thereby achieving the purpose of desulfurization and denitrification. No more details will be given here. After the desulfurization and denitrification treatment, the waste gas passes through the inside of the elastic filter cloth 12 and finally passes through the air outlet on the side wall of the treatment box 1 9 is discharged, wherein when the exhaust gas is desulfurized, denitrated and dust-removed, the motor 6 can also be started, and the motor 6 is fixed to the top of the treatment box 1. The motor 6 drives the fixed plate 15 to rotate through the rotating rod 14, and the fixed plate 15 drives the filter plate 10 to vibrate up and down through the vibration mechanism 3. Since the filter plate 10 is a bamboo hat structure (the cross section of the filter plate 10 is a conical or truncated cone structure), under the action of the vibration mechanism 3, the particulate impurities on the top of the filter plate 10 will slide toward the inner wall of the treatment box 1. When the particulate impurities slide to the edge of the filter plate 10, the cleaning mechanism 4 will automatically clean the particulate impurities to the outside of the treatment box 1, which can effectively avoid the particulate impurities in the filter The accumulation phenomenon on the surface of the mesh plate 10 ensures the normal flow of exhaust gas, and at the same time, there is no need for staff to clean the particulate impurities on the surface of the filter mesh plate 10, saving manpower. While the filter mesh plate 10 vibrates up and down, the elastic filter cloth 12 is periodically supported by the supporting mechanism 5. When the supporting mechanism 5 supports the elastic filter cloth 12, the elastic filter cloth 12 is deformed inward. At this time, the spraying mechanism 2 will spray the reaction liquid on the surface of the elastic filter cloth 12, thereby forming a layer of reaction liquid film on the surface of the elastic filter cloth 12. When the exhaust gas passes through the inside of the elastic filter cloth 12, the harmful substances in the exhaust gas will react with the reaction liquid film, thereby causing the reaction liquid film to The liquid can fully react with the harmful substances in the exhaust gas, effectively ensuring the desulfurization and denitrification effect. That is, the industrial exhaust gas desulfurization and denitrification dust removal equipment significantly improves the exhaust gas purification efficiency by integrating vibration filtration, dynamic spray reaction and elastic filter cloth 12 deformation technology. The use of a bamboo hat-shaped filter plate 10 combined with a vibration mechanism 3 allows the particles to automatically slide to the edge under the action of vibration and be discharged through the cleaning mechanism 4, effectively preventing blockage and reducing the need for manual cleaning; the elastic filter cloth 12 is periodically deformed under the action of the supporting mechanism 5, and cooperates with the spray system to form a dynamic reaction liquid film, thereby increasing the gas-liquid contact area and strengthening the desulfurization and denitrification reaction effect, which can significantly reduce the particulate matter in the industrial exhaust gas, and The emission concentration meets environmental protection requirements.

[0029] See also Figure 1 and Figure 4The spray mechanism 2 includes a spray plate 25 fixedly connected to the bottom of the partition 11. A channel is provided inside the partition 11, and the other end of the channel is connected to a water inlet pipe 21, wherein the water inlet pipe 21 is connected to a water pump 23. A reaction liquid tank 24 is provided outside the treatment box 1, and the reaction liquid tank 24 is connected to the water inlet pipe 21;

[0030] When treating the exhaust gas, the exhaust gas enters the inner side of the elastic filter cloth 12 through the through hole 16 inside the partition 11. At this time, under the action of the water pump 23, the reaction liquid inside the reaction liquid tank 24 enters the channel inside the partition 11 through the water inlet pipe 21. The reaction liquid follows the channel inside the partition 11 into the inside of the spray plate 25, and is finally discharged from the water outlet at the bottom of the spray plate 25. At this time, the reaction liquid can react chemically with the harmful substances in the exhaust gas.

[0031] See also Figure 7 , a drain port 17 is provided at the bottom of the reaction liquid tank 24 and inside the elastic filter cloth 12, and a seal is provided at the drain port 17. The lower end of the side wall of the treatment box 1 is connected to a water outlet pipe 22, and the other end of the water outlet pipe 22 is connected to the reaction liquid tank 24;

[0032] When the exhaust gas is treated, the exhaust gas enters the inner side of the elastic filter cloth 12 through the through hole 16 inside the partition 11. At this time, the reaction liquid and the harmful substances in the exhaust gas can undergo a chemical reaction, and the precipitate generated by the reaction will be deposited at the bottom of the treatment box 1 and the inner side of the elastic filter cloth 12. The reaction liquid that has not fully reacted passes through the elastic filter cloth 12 and enters the reaction liquid box 24 again through the outlet pipe 22, thereby fully utilizing the reaction liquid and avoiding the accumulation of the reaction liquid inside the treatment box 1. When there is a lot of sediment at the bottom of the treatment box 1 and the inner side of the elastic filter cloth 12, the seal is opened and the sediment is directly discharged from the sewage outlet 17, which is convenient for the staff to clean the sediment inside the treatment box 1.

[0033] See also Figure 2 and Figure 5 , the cleaning mechanism 4 includes a scraper 43 arranged above the filter screen 10, a slide rod 41 is fixed to the top of the scraper 43, the slide rod 41 passes through the fixed plate 15 and is slidably connected to the fixed plate 15, a second elastic member 42 is provided on the outside of the slide rod 41, and the two ends of the second elastic member 42 are respectively fixedly connected to the bottom of the fixed plate 15 and the top of the scraper 43, the filter screen 10 is passed through a position close to the inner wall of the processing box 1 with a drainage pipe 8, the top of the drainage pipe 8 is flush with the top of the filter screen 10, and the lower end of the drainage pipe 8 passes through the side wall of the processing box 1;

[0034] When the exhaust gas is desulfurized, denitrified and dust-removed, the motor 6 is started, and the motor 6 drives the fixed plate 15 to rotate through the rotating rod 14. While the fixed plate 15 rotates, the scraper 43 is driven to make a circular motion through the sliding rod 41. The scraper 43 of the circular motion cleans the particulate impurities on the top of the filter screen plate 10. In the cleaning process, the scraper 43 pushes the impurities on the top of the filter screen plate 10. Since the filter screen plate 10 is close to the inner wall of the treatment box 1, there is a discharge pipe 8 passing through it. When the particulate dust on the surface of the filter screen plate 10 is pushed to a certain position, the particulate impurities will automatically fall into the discharge pipe 8, thereby playing a role in cleaning the particulate impurities on the surface of the filter screen plate 10. The filter screen 10 is provided with an automatic cleaning function to prevent particulate matter and impurities from clogging the filter screen 10. The scraper 43 is connected to the fixed plate 15 through the second elastic member 42. The second elastic member 42 can play an elastic supporting role on the filter screen 10, thereby preventing the scraper 43 from interfering with the vibration of the filter screen 10. The second elastic member 42 can be a spring. In addition, the drain pipe 8 can be L-shaped, and the upper part of the drain pipe 8 can be a hose, such as a bellows. At the same time, a sealing valve can be provided at the lower end of the drain pipe 8 to seal the drain pipe 8, thereby preventing exhaust gas from leaking from the inside of the drain pipe 8. When there are more particulate matter and impurities in the drain pipe 8, the sealing valve can be opened.

[0035] See also Figure 2 and Figure 5 The vibration mechanism 3 includes a first magnet 31 fixedly connected to the bottom of the fixed plate 15, a second magnet 32 capable of repelling the first magnet 31 is fixed to the top of the filter screen 10, and a first elastic member 33 symmetrically distributed is fixed to the bottom of the filter screen 10, and the bottom of the first elastic member 33 is fixedly connected to the top of the partition 11;

[0036] When the exhaust gas is desulfurized, denitrified and dust-removed, the motor 6 is started, and the motor 6 drives the fixed plate 15 to rotate through the rotating rod 14. The fixed plate 15 rotates while driving the first magnet 31 at its bottom to make a circular motion. When the first magnet 31 rotates above the second magnet 32, the first magnet 31 and the second magnet 32 repel each other, thereby causing the filter plate 10 to move downward. As the fixed plate 15 continues to rotate, the first magnet 31 and the second magnet 32 no longer repel each other, and the filter plate 10 automatically resets under the action of the first elastic member 33. The first elastic member 33 can be a spring. This cycle is repeated, so that the filter plate 10 can continuously vibrate up and down, thereby prompting the particulate impurities on the surface of the filter plate 10 to move toward the side wall of the treatment box 1, effectively avoiding the phenomenon of particulate impurities blocking the filter plate 10, and ensuring the normal flow of exhaust gas.

[0037] See also Figure 3The supporting mechanism 5 includes a plurality of top plates 52 fixedly connected to the outer wall of the elastic filter cloth 12, a support rod 54 fixedly connected to the top plate 52, a plurality of guide plates 53 fixed to the bottom of the processing box 1, the support rod 54 passes through the guide plate 53 and is slidably connected to the guide plate 53, the end of the support rod 54 is rotatably connected to the first connecting rod 55, the other end of the first connecting rod 55 is rotatably connected to the first movable rod 51, the first movable rod 51 passes through the partition 11 and is slidably connected to the partition 11, and the top of the first movable rod 51 is fixedly connected to the bottom of the filter screen plate 10;

[0038] When treating the exhaust gas, the vibration mechanism 3 drives the filter screen 10 to vibrate up and down. While the filter screen 10 vibrates up and down, it drives the first movable rod 51 to move up and down. Under the limit of the guide plate 53, the first movable rod 51 moves up and down while driving the support rod 54 to move back and forth horizontally through the first connecting rod 55. The support rod 54 periodically squeezes the elastic filter cloth 12 through the top plate 52. When the elastic filter cloth 12 is deformed inward, the spray mechanism 2 will spray the reaction liquid on the surface of the elastic filter cloth 12, thereby forming a layer of reaction liquid film on the surface of the elastic filter cloth 12. When the exhaust gas passes through the inside of the elastic filter cloth 12, the harmful substances in the exhaust gas will react with the reaction liquid film, thereby increasing the gas-liquid contact area and enhancing the desulfurization and denitrification effects.

[0039] In another embodiment, see Figure 3 , wherein the two symmetrically distributed first movable rods 51 are connected to a fixing assembly, and when the first movable rod 51 moves to the lowest point, the fixing assembly automatically fixes the first movable rod 51;

[0040] In this embodiment, when the exhaust gas is treated, the filter plate 10 drives the first movable rod 51 to move up and down under the action of the vibration mechanism 3. When the first movable rod 51 moves to the lowest point, the fixing component automatically fixes the first movable rod 51. At this time, the pressure plate 512 squeezes the elastic filter cloth 12 to the maximum extent. When the fixing component no longer fixes the first movable rod 51, the filter plate 10 automatically resets under the action of the first elastic member 33, thereby driving the top plate 52 to automatically reset. On the one hand, the filter plate 10 can move upward quickly, thereby increasing the vibration intensity of the filter plate 10 and ensuring the shaking effect on particulate impurities. On the other hand, it extends the support time of the top plate 52 on the elastic filter cloth 12, so that more reaction liquid can fall on the surface of the elastic filter cloth 12, further promoting the reaction effect between the reaction liquid and harmful substances.

[0041] See also Figure 3 and Figure 6The fixing assembly includes a pin rod 56 that passes through the side wall of the processing box 1 and the side wall of the partition 11. One end of the pin rod 56 is connected to the outer wall of the first movable rod 51, and the other end of the pin rod 56 is connected to an elastic support component. The elastic support component is used to provide elastic support force for the pin rod 56. The side wall of the first movable rod 51 is provided with a pin groove 57 that is compatible with the pin rod 56.

[0042] When treating the exhaust gas, the filter plate 10 drives the first movable rod 51 to move up and down under the action of the vibration mechanism 3. When the first movable rod 51 moves to the lowest point, the pin rod 56 is aligned with the pin groove 57. The pin rod 56 automatically enters the pin groove 57 under the action of the elastic support component, and the pin rod 56 fixes the first movable rod 51 through the pin groove 57.

[0043] See also Figure 6 , the elastic support component includes a second connecting rod 58 rotatably connected to the end of the pin rod 56, and the other end of the second connecting rod 58 is rotatably connected to the second movable rod 59, a positioning plate 510 is fixed on the side wall of the processing box 1, the second movable rod 59 passes through the positioning plate 510 and is slidably connected to the positioning plate 510, and a pressing plate 512 is fixed on the top of the second movable rod 59, and the pressing plate 512 is connected to the positioning plate 510 through a third elastic member 511, wherein an extrusion member is provided above the pressing plate 512, and the extrusion member is used to squeeze the pressing plate 512;

[0044] When the exhaust gas is processed, the filter plate 10 drives the first movable rod 51 to move up and down under the action of the vibration mechanism 3. At this time, the end of the pin rod 56 is connected to the side wall of the first movable rod 51, and the third elastic member 511 is in a compressed state. When the first movable rod 51 moves to the lowest point, the pin rod 56 is aligned with the pin groove 57, and the third elastic member 511 releases elastic potential energy, thereby driving the second movable rod 59 to move upward through the pressure plate 512. The third elastic member 511 can be a spring, and the second movable rod 59 moves upward. At the same time, the pin rod 56 is driven to move by the connecting rod, so that the pin rod 56 is inserted into the pin groove 57, thereby fixing the movable rod. When the extrusion member squeezes the pressure plate 512, the pressure plate 512 drives the second movable rod 59 to move downward, and the second movable rod 59 drives the pin rod 56 to move through the second connecting rod 58, thereby pulling the pin rod 56 out of the pin groove 57, thereby releasing the fixation of the pin rod 56 to the first movable rod 51, so that the filter plate 10 can automatically reset and the elastic filter cloth 12 can rebound.

[0045] See also Figure 1The extrusion member includes a transmission rod 514 that passes through the side wall of the processing box 1. The transmission rod 514 is rotatably connected to the side wall of the processing box 1. An extrusion block 513 capable of extruding the pressure plate 512 is fixed to one end of the transmission rod 514. A first bevel gear 515 is fixed to the other end of the transmission rod 514. A second bevel gear 516 is fixed to the outside of the rotating rod 14. The first bevel gear 515 is meshed with the second bevel gear 516.

[0046] When the exhaust gas is treated, the motor 6 drives the rotating rod 14 to rotate. While the rotating rod 14 rotates, the transmission rod 514 is driven to rotate through the engagement of the first bevel gear 515 and the second bevel gear 516. When the transmission rod 514 rotates to a certain extent, the transmission rod 514 squeezes the pressure plate 512 through the extrusion block 513, and the pressure plate 512 drives the second movable rod 59 to move downward. The second movable rod 59 drives the pin rod 56 to move through the second connecting rod 58, thereby pulling the pin rod 56 out of the pin groove 57, thereby releasing the pin rod 56 from the first movable rod 51.

[0047] Working principle: When desulfurization, denitrification and dust removal are carried out on industrial waste gas, the waste gas enters the inside of the treatment box 1 through the air inlet 7 on the top of the treatment box 1, and is filtered by the filter plate 10 inside the treatment box 1 to remove particulate impurities in the waste gas. After passing through the filter plate 10, the waste gas enters the inside of the elastic filter cloth 12 through the through hole 16. At this time, under the action of the water pump 23, the reaction liquid inside the reaction liquid tank 24 enters the inside of the channel inside the partition 11 through the water inlet pipe 21, and the reaction liquid enters the inside of the spray plate 25 along the channel inside the partition 11, and is finally discharged from the water outlet at the bottom of the spray plate 25. The reaction liquid reacts chemically with the harmful substances in the waste gas to achieve the purpose of desulfurization and denitrification. The waste gas undergoes desulfurization and denitrification. After treatment, it passes through the elastic filter cloth 12 and is finally discharged through the air outlet 9 on the side wall of the treatment box 1. When the exhaust gas is desulfurized, denitrified and dust-removed, the motor 6 can also be started. The motor 6 drives the fixed plate 15 to rotate through the rotating rod 14. While the fixed plate 15 rotates, the scraper 43 is driven to make a circular motion through the sliding rod 41. The scraper 43 of the circular motion cleans the particulate impurities on the top of the filter screen plate 10. During the cleaning process, the scraper 43 pushes the impurities on the top of the filter screen plate 10. Since the filter screen plate 10 is close to the inner wall of the treatment box 1, there is a discharge pipe 8 running through it. When the particulate dust on the surface of the filter screen plate 10 is pushed to a certain position, the particulate impurities will automatically fall into the discharge pipe 8, thereby cleaning the filter screen. The particle impurities on the surface of the plate 10 play an automatic cleaning role, avoiding the phenomenon that the particle impurities block the filter plate 10. In addition, the fixed plate 15 rotates while driving the first magnet 31 at its bottom to make a circular motion. When the first magnet 31 rotates above the second magnet 32, the first magnet 31 and the second magnet 32 repel each other, thereby causing the filter plate 10 to move downward. As the fixed plate 15 continues to rotate, the first magnet 31 and the second magnet 32 no longer repel each other, and the filter plate 10 automatically resets. This cycle is repeated, allowing the filter plate 10 to continuously vibrate up and down, thereby prompting the particle impurities on the surface of the filter plate 10 to move toward the side wall of the processing box 1, effectively avoiding the particle impurities from filtering The blockage of the mesh plate 10 ensures the normal flow of exhaust gas, and the filter mesh plate 10 vibrates up and down while driving the first movable rod 51 to move up and down. Under the limit of the guide plate 53, the first movable rod 51 moves up and down while driving the support rod 54 to move back and forth horizontally through the first connecting rod 55. The support rod 54 periodically squeezes the elastic filter cloth 12 through the top plate 52. When the elastic filter cloth 12 is deformed inward, the spray mechanism 2 will spray the reaction liquid on the surface of the elastic filter cloth 12, thereby forming a layer of reaction liquid film on the surface of the elastic filter cloth 12. When the exhaust gas passes through the inside of the elastic filter cloth 12, the harmful substances in the exhaust gas will react with the reaction liquid film, thereby increasing the gas-liquid contact area and enhancing the desulfurization and denitrification effect.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
