Description

Technical Field

[0001] The present invention relates to the technical field of desulfurization and denitrification, and specifically relates to a desulfurization, denitrification and dust removal tower. Background Art

[0002] Sulfur dioxide and nitrogen oxides are gaseous pollutants with greater impacts among atmospheric pollutants, and have great harms to humans, the environment and the ecosystem. With the increasingly strict environmental protection requirements, the problems of sulfur dioxide and nitrogen oxide emissions have received more and more attention. Sulfur dioxide and nitrogen oxides mainly come from the combustion processes of fossil fuels such as coal and oil, as well as the flue gas emissions from the roasting and smelting processes of ores. Among them, the flue gas discharged from various combustion boilers, especially those in thermal power plants, has the characteristics of low concentration, large flue gas volume and a lot of floating dust, making it difficult to treat. In traditional technologies, the purification technologies for sulfur dioxide and nitrogen oxides in the discharged flue gas usually carry out desulfurization and denitrification separately, which results in defects such as a complex and large discharged flue gas purification system, high initial investment and high operating costs, severely restricting the actual implementation of desulfurization and denitrification of discharged flue gas.

[0003] In the prior art, there has also been a patent on a technical solution for a desulfurization, denitrification and dust removal tower. For example, a Chinese patent with the application number CN2020103926303 discloses a desulfurization, denitrification and dust removal tower, including a cylindrical main body; an exhaust pipe for exhausting gas is provided at the top of the main body, a drain pipe is provided on one side of the bottom of the main body, and an intake pipe communicating with sulfur-containing waste gas is provided on the side of the bottom of the main body away from the drain pipe. A cylindrical base is provided at the inner bottom of the main body, and a first hole is opened in the base; the intake pipe penetrates through the main body and communicates with the first hole; a turntable is rotatably connected to the top of the base, and first pipes are symmetrically connected to the turntable. The first pipes communicate with the first hole through a second hole opened in the turntable; one end of the first pipe away from the turntable communicates with a second pipe, the first pipe and the second pipe are perpendicular to each other, and the two second pipes are centrosymmetric about the axis of the turntable.

[0004] The above prior art, by setting the first pipe, the turntable, the second hole and the second pipe, enables the air flow ejected from the second pipe to drive the first pipe to rotate, further increasing the desulfurization efficiency of the waste gas; however, when the above-mentioned desulfurization, denitrification and dust removal tower is in use, the sulfur-containing waste gas is directly discharged through the exhaust pipe after being filtered, so that the sulfur-containing waste gas undergoes single desulfurization and denitrification, and the desulfurization process is relatively single, and the sulfur-containing waste gas cannot be secondarily filtered, resulting in poor filtration efficiency.

[0005] In view of this, the present invention provides a desulfurization, denitrification and dust removal tower to solve the above problems. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve the problem that when the desulfurization, denitrification and dust removal tower used in the prior art is in use, the sulfur-containing waste gas is directly discharged through the exhaust pipe after filtration, so that the sulfur-containing waste gas undergoes single desulfurization and denitrification, and the desulfurization process is relatively single, and the sulfur-containing waste gas cannot be filtered twice, resulting in poor filtration efficiency; the present invention proposes a desulfurization, denitrification and dust removal tower.

[0007] The technical solution adopted by the present invention to solve its technical problems is: a desulfurization, denitrification and dust removal tower, including a housing, a cover body and a motor; a water inlet pipe and an air inlet pipe are fixedly connected to the lower side of the outer circle of the housing, the air inlet pipe is located directly below the water inlet pipe, an air outlet pipe is fixedly connected to the lower end of the housing, a motor is fixedly connected to the center position of the lower end surface of the housing, and the output shaft of the motor passes through the housing and is located inside the housing; an air outlet pipe is arranged on the upper end surface of the cover body; a driving shaft is fixedly connected to the center position of the lower end of the housing, a first plate is evenly fixedly connected to the outer circle of the driving shaft, a rotating shaft is fixedly connected to the center position of the upper end of the driving shaft, a first filter screen is slidably connected to the outer circle of the rotating shaft, the outer circle of the first filter screen is fixedly connected to the inner wall of the housing, a second plate is arranged at the upper end of the rotating shaft, a rectangular groove is opened at the upper end of the rotating shaft, a rectangular block is fixedly connected to the lower end of the second plate, the rectangular block is slidably connected in the rectangular groove, a first groove is opened on the inner wall of the housing, the first groove is annular, a first convex block is evenly fixedly connected to the lower side of the outer circle of the second plate, a second convex block is evenly fixedly connected to the lower groove wall of the first groove, the lower end of the first convex block is arc-shaped, the upper end of the second convex block is arc-shaped, and a through hole is opened through the upper and lower sides of the second convex block plate;

[0008] In use, the desulfurization and denitrification liquid is poured into the interior of the housing through the water inlet pipe, so that the liquid level of the desulfurization and denitrification liquid is located above the upper end face of the driving shaft, and at the same time the liquid level is located below the first filter screen. Then, waste gas is flushed into the inner wall of the housing through the air inlet pipe. Subsequently, the motor is started. When the motor rotates, the motor drives the driving shaft to rotate. When the driving shaft drives the first plate to rotate, the first plate stirs the desulfurization and denitrification liquid inside, making the waste gas and the desulfurization and denitrification liquid mix more evenly. Then, after the waste gas is filtered by the desulfurization and denitrification liquid and continues to be poured into the interior of the housing, the gas after being filtered by the desulfurization and denitrification liquid moves upward. When the filtered gas moves upward, the gas passes through the first filter screen, so that the first filter screen filters the dust and impurities in the gas, thereby improving the cleanliness of the gas. And when the motor rotates, the driving shaft rotates, and the driving shaft drives the rotating shaft to rotate. The first filter screen is slidably connected to the rotating shaft. When the rotating shaft rotates, the first filter screen does not move. And by providing a rectangular groove on the upper end face of the rotating shaft and a rectangular block on the lower end face of the second plate, the rectangular block is located in the rectangular groove. When the rotating shaft rotates, through the engagement between the rectangular groove and the rectangular block, and the second plate is located in the first groove on the inner wall of the housing, the side wall of the first groove limits the second plate, so that the rotating shaft drives the second plate to rotate. When the second plate rotates, the second plate drives the first convex block at the lower end to move. The contact end of the first convex block and the second convex block is arc-shaped. When the first convex block moves, it presses against the second convex block, so that the second plate vibrates up and down. When the second plate vibrates up and down, the second plate squeezes the gas passing through the first filter screen, so that the gas passes through the first filter screen again and returns below the first filter screen. Then the gas passes through the first filter screen again. Through the up and down vibration of the second plate, the first filter screen realizes multiple filtrations of the gas. And the filtered gas flows to the upper side of the second plate through the through holes on the second plate, and then flows out through the air outlet pipe. And the desulfurization and denitrification liquid after long-term use is discharged from the water outlet pipe, thereby improving the desulfurization efficiency of the gas.

[0009] Preferably, the lower end face of the second plate is uniformly and fixedly connected with third convex blocks, and the third convex blocks are in contact with the upper end face of the first filter screen in the initial state;

[0010] During use, three convex blocks are evenly fixedly connected to the lower end of the second plate, so that the three convex blocks are in contact with the upper end surface of the first filter screen in the initial state. When the motor rotates, the motor drives the driving shaft to rotate, and the driving shaft drives the rotating shaft to rotate. When the rotating shaft rotates, the rotating shaft drives the second plate to rotate through the rectangular block in the rectangular groove. When the second plate rotates, the first convex block at the lower end of the second plate presses against the second convex block in the first groove, causing the second plate to vibrate up and down when it rotates. When the third convex block at the upper end of the second plate vibrates up and down, the third convex block presses against the first filter screen, causing the first filter screen to vibrate. When the first filter screen vibrates, the impurities on the surface of the first filter screen vibrate and fall off, thereby improving the subsequent filtration efficiency of the first filter screen.

[0011] Preferably, the first plate is arranged in multiple layers, and the shapes of the layers of the first plate are fan-shaped;

[0012] During use, by arranging the first plate in multiple layers and making the shapes of the layers of the first plate fan-shaped, when the motor rotates, the motor drives the driving shaft to rotate. When the driving shaft rotates, the driving shaft drives the first plate to rotate. When the first plate rotates, since the first plate is arranged in multiple layers and each layer is fan-shaped, when the first plate rotates, the first plate stirs the desulfurization and denitrification liquid inside, and when the first plate rotates, each layer of the first plate is fan-shaped, causing the desulfurization and denitrification liquid to roll upward, so that when the gas enters the desulfurization and denitrification liquid, the mixing efficiency of the waste gas and the desulfurization and denitrification liquid increases.

[0013] Preferably, second filter screens are fixedly connected between adjacent layers of the first plate;

[0014] During use, by evenly fixedly connecting second filter screens between adjacent layers of the first plate, when the motor rotates, the motor drives the driving shaft to rotate actively. When the driving shaft rotates, the first plate rotates. By evenly fixedly connecting second filter screens between the layers of the first plate, on the one hand, when the first plate rotates, the second filter screens filter the dust in the waste gas, increasing the desulfurization and denitrification efficiency when the waste gas undergoes desulfurization and denitrification; on the other hand, when the second filter screens rotate in the desulfurization and denitrification liquid along with the driving shaft, the filter holes on the second filter screens disperse the waste gas entering the desulfurization and denitrification liquid from the intake pipe, causing the bubbles of the waste gas entering the desulfurization and denitrification liquid to be dispersed, thereby increasing the contact area between the waste gas and the desulfurization and denitrification liquid, and thus improving the desulfurization and denitrification efficiency of the desulfurization and denitrification liquid for the waste gas.

[0015] Preferably, L-shaped grooves are evenly formed inside the housing. The lower ends of the L-shaped grooves communicate with the first groove. A first slider and a second slider are slidably connected in the L-shaped grooves. One end of the first slider extends into the first groove. The second slider is parallel to the horizontal plane. A return spring is sleeved outside the second slider, and one end of the second slider contacts the upper end of the first slider. Liquid infusion tubes are fixedly connected to the upper openings of the L-shaped grooves. One end of the second slider extends into the liquid infusion tubes. Atomizing nozzles are evenly arranged at the lower ends of the liquid infusion tubes. A first tube is arranged at the intersection of the plurality of liquid infusion tubes. The lower end of the first tube communicates with the liquid infusion tubes. The upper end of the first tube passes through the cover body and is located on the upper surface of the cover body. A water tank is arranged on the upper surface of the cover body. A desulfurization and denitrification liquid is contained in the water tank. The water tank communicates with the first tube;

[0016] During use, L-shaped grooves are evenly formed inside the housing, and a first slider and a second slider are slidably connected inside the L-shaped grooves, so that one end of the first slider extends into the first groove. When the motor rotates, the motor drives the driving shaft to rotate, and the driving shaft drives the second plate to rotate. When the second plate rotates, the first convex block and the second convex block are pressed, causing the second plate to vibrate up and down. When the second plate vibrates upward, the second plate presses the first slider, and the first slider moves upward. When the first slider slides, it presses the second slider. The second slider is pressed and moves into the liquid infusion tube. The return spring is used to reset the second slider and the first slider. When the second slider moves, the desulfurization and denitrification liquid in the water tank flows into the liquid infusion tube through the first tube under the action of its own gravity. The second slider applies hydraulic pressure to the desulfurization and denitrification liquid inside the liquid infusion tube, causing the desulfurization and denitrification liquid to spray out of the atomizing nozzle, making the desulfurization and denitrification liquid flow downward in a mist shape to filter the waste gas. When the desulfurization and denitrification liquid descends in a mist shape, the misty liquid causes the gas to flow downward in a reflux, providing conditions for secondary filtration of the waste gas, thereby improving the filtration efficiency of the waste gas. And by arranging the first tube at the upper end of the liquid infusion tube, connecting the upper end of the first tube to the water tank, and communicating the lower end of the first tube with the liquid infusion tube, the desulfurization and denitrification liquid inside the water tank flows through the first tube into the liquid infusion tube, so that the liquid infusion tube is always filled with the desulfurization and denitrification liquid, thereby ensuring the continuity of the desulfurization and denitrification liquid.

[0017] Preferably, fan-shaped pieces are evenly arranged in the through holes, and the arc-shaped edges of the fan-shaped pieces are hinged to the inner walls of the through holes;

[0018] During use, sector-shaped pieces are evenly arranged in the through holes, and the arc-shaped edges of the sector-shaped pieces are hinged to the inner walls of the through holes. When the motor rotates, the motor drives the driving shaft to rotate, and the driving shaft drives the rotating shaft to rotate. When the rotating shaft rotates, through the engagement between the rectangular groove of the rotating shaft and the rectangular block on the second plate, the second plate rotates. When the second plate rotates, the first convex block at the lower end of the second plate presses against the second convex block in the first groove, thereby causing the second plate to vibrate up and down. When the second plate moves downward, the second plate presses the air below, and the gas flows back downward, enabling the first filter screen to filter the flowing-back gas multiple times, thereby improving the cleanliness of the gas. Moreover, when the second plate presses the gas, the gas generates a reaction force on the second plate, causing the middle of the sector-shaped piece to open, thereby allowing the gas to pass through, thus improving the gas filtration efficiency.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. For the desulfurization, denitrification, and dust removal tower of the present invention, by setting a motor, a driving shaft, a first plate, and a second filter screen; when the first plate rotates, the second filter screen filters the dust in the waste gas, increasing the desulfurization and denitrification efficiency when the waste gas undergoes desulfurization and denitrification. On the other hand, when the second filter screen rotates in the desulfurization and denitrification liquid along with the driving shaft, the filter holes on the second filter screen disperse the waste gas entering the desulfurization and denitrification liquid from the intake pipe, causing the bubbles of the waste gas entering the desulfurization and denitrification liquid to be dispersed, thereby increasing the contact area between the waste gas and the desulfurization and denitrification liquid, and thus improving the desulfurization and denitrification efficiency of the desulfurization and denitrification liquid for the waste gas.

[0021] 2. For the desulfurization, denitrification, and dust removal tower of the present invention, by setting a second plate, a through hole, and a sector-shaped piece; when the second plate rotates, the first convex block at the lower end of the second plate presses against the second convex block in the first groove, thereby causing the second plate to vibrate up and down. When the second plate moves downward, the second plate presses the air below, and the gas flows back downward, enabling the first filter screen to filter the flowing-back gas multiple times, thereby improving the cleanliness of the gas. Moreover, when the second plate presses the gas, the gas generates a reaction force on the second plate, causing the middle of the sector-shaped piece to open, thereby allowing the gas to pass through, thus improving the gas filtration efficiency.

Specific embodiments

[0028] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0029] As Figures 1 to 4 shown, a desulfurization, denitrification and dust removal tower includes a housing 1, a cover 11 and a motor 12; a water inlet pipe 13 and an air inlet pipe 14 are fixedly connected to the lower side of the outer circle of the housing 1, the air inlet pipe 14 is located directly below the water inlet pipe 13, an air outlet pipe 15 is fixedly connected to the lower end of the housing 1, a motor 12 is fixedly connected to the center position of the lower end surface of the housing 1, and the output shaft of the motor 12 passes through the housing 1 and is located inside the housing 1; an air outlet pipe 15 is arranged on the upper end surface of the cover 11; a driving shaft 2 is fixedly connected to the center position of the lower end of the housing 1, a first plate 21 is uniformly fixedly connected to the outer circle of the driving shaft 2, a rotating shaft 22 is fixedly connected to the center position of the upper end of the driving shaft 2, a first filter screen 23 is slidably connected to the outer circle of the rotating shaft 22, the outer circle of the first filter screen 23 is fixedly connected to the inner wall of the housing 1, a second plate 24 is arranged at the upper end of the rotating shaft 22, a rectangular groove 221 is opened at the upper end of the rotating shaft 22, a rectangular block 241 is fixedly connected to the lower end of the second plate 24, the rectangular block 241 is slidably connected in the rectangular groove 221, a first groove 16 is opened on the inner wall of the housing 1, the first groove 16 is annular, a first convex block 242 is uniformly fixedly connected to the lower side of the outer circle of the second plate 24, a second convex block 161 is uniformly fixedly connected to the lower groove wall of the first groove 16, the lower end of the first convex block 242 is arc-shaped, the upper end of the second convex block 161 is arc-shaped, and a through hole 243 is opened through the upper and lower sides of the second convex block 161 plate;

[0030] During use, the desulfurization and denitrification liquid is poured into the inside of the housing 1 through the water inlet pipe 13, so that the liquid level of the desulfurization and denitrification liquid is located at the upper end face of the driving shaft 2, and at the same time the liquid level is located below the first filter screen 23. Then, waste gas is introduced into the inner wall of the housing 1 through the air inlet pipe 14. Subsequently, the motor 12 is started. When the motor 12 rotates, the motor 12 drives the driving shaft 2 to rotate. When the driving shaft 2 drives the first plate 21 to rotate, the first plate 21 stirs the desulfurization and denitrification liquid inside, making the mixing of the waste gas and the desulfurization and denitrification liquid more uniform. Then, after the waste gas is filtered by the desulfurization and denitrification liquid and continues to be introduced into the inside of the housing 1, the gas after being filtered by the desulfurization and denitrification liquid moves upward. When the filtered gas moves upward, the gas passes through the first filter screen 23, so that the first filter screen 23 filters the dust and impurities in the gas, thereby improving the cleanliness of the gas. And when the motor 12 rotates, the driving shaft 2 rotates, and the driving shaft 2 drives the rotating shaft 22 to rotate. The first filter screen 23 is slidably connected to the rotating shaft 22. When the rotating shaft 22 rotates, the first filter screen 23 does not move. And by providing a rectangular groove 221 on the upper end face of the rotating shaft 22 and a rectangular block 241 on the lower end face of the second plate 24, the rectangular block 241 is located in the rectangular groove 221. When the rotating shaft 22 rotates, through the engagement between the rectangular groove 221 and the rectangular block 241, and the second plate 24 is located in the first groove 16 on the inner wall of the housing 1, the side wall of the first groove 16 limits the second plate 24, so that the rotating shaft 22 drives the second plate 24 to rotate. When the second plate 24 rotates, the second plate 24 drives the first convex block 242 at the lower end to move. The contact end of the first convex block 242 and the second convex block 161 is arc-shaped. When the first convex block 242 moves, it presses against the second convex block 161, so that the second plate 24 vibrates up and down. When the second plate 24 vibrates up and down, the second plate 24 squeezes the gas passing through the first filter screen 23, so that the gas passes through the first filter screen 23 again and returns to the lower side of the first filter screen 23. Then the gas passes through the first filter screen 23 again. Through the up and down vibration of the second plate 24, the first filter screen 23 realizes multiple filtrations of the gas. And the filtered gas flows to the upper side of the second plate 24 through the through holes 243 on the second plate 24, and then flows out through the air outlet pipe 15. And the desulfurization and denitrification liquid after long-term use is discharged from the water outlet pipe, thereby improving the desulfurization efficiency of the gas.

[0031] As a specific embodiment of the present invention, the lower end face of the second plate 24 is uniformly and fixedly connected with third convex blocks 244, and the third convex blocks 244 are in contact with the upper end face of the first filter screen 23 in the initial state;

[0032] During use, third bumps 244 are evenly fixedly connected to the lower end of the second plate 24, so that the third bumps 244 are in contact with the upper end surface of the first filter screen 23 in the initial state. When the motor 12 rotates, the motor 12 drives the driving shaft 2 to rotate, and the driving shaft 2 drives the rotating shaft 22 to rotate. When the rotating shaft 22 rotates, the rotating shaft 22 drives the second plate 24 to rotate through the rectangular block 241 in the rectangular groove 221. When the second plate 24 rotates, the first bump 242 at the lower end of the second plate 24 presses against the second bump 161 in the first groove 16, so that when the second plate 24 rotates, the second plate 24 vibrates up and down. When the third bump 244 at the upper end of the second plate 24 vibrates up and down, the third bump 244 presses against the first filter screen 23, causing the first filter screen 23 to vibrate. When the first filter screen 23 vibrates, the impurities on the surface of the first filter screen 23 vibrate and fall off, thereby improving the subsequent filtration efficiency of the first filter screen 23.

[0033] As a specific embodiment of the present invention, the first plate 21 is arranged in multiple layers, and each layer of the first plate 21 is in the shape of a fan blade.

[0034] During use, by arranging the first plate 21 in multiple layers and making each layer of the first plate 21 in the shape of a fan blade, when the motor 12 rotates, the motor 12 drives the driving shaft 2 to rotate. When the driving shaft 2 rotates, the driving shaft 2 drives the first plate 21 to rotate. When the first plate 21 rotates, since the first plate 21 is arranged in multiple layers and each layer is in a fan shape, when the first plate 21 rotates, the first plate 21 stirs the desulfurization and denitrification liquid inside, and when the first plate 21 rotates, each layer of the first plate 21 is in the shape of a fan blade, causing the desulfurization and denitrification liquid to roll upward, so that when the gas enters the desulfurization and denitrification liquid, the mixing efficiency of the waste gas and the desulfurization and denitrification liquid increases.

[0035] As a specific embodiment of the present invention, second filter screens 211 are fixedly connected between adjacent layers of the first plate 21.

[0036] During use, second filters 211 are uniformly fixedly connected between adjacent layers of the first plate 21. When the motor 12 rotates, the motor 12 drives the main shaft 2 to rotate. When the main shaft 2 rotates, the first plate 21 rotates. Since the second filters 211 are uniformly fixedly connected between the layers of the first plate 21, on the one hand, when the first plate 21 rotates, the second filters 211 filter the dust in the waste gas, increasing the desulfurization and denitrification efficiency when the waste gas undergoes desulfurization and denitrification. On the other hand, when the second filters 211 rotate in the desulfurization and denitrification liquid along with the main shaft 2, the filter holes on the second filters 211 disperse the waste gas entering the desulfurization and denitrification liquid from the intake pipe 14, breaking up the bubbles of the waste gas entering the desulfurization and denitrification liquid from the intake pipe 14, thereby increasing the contact area between the waste gas and the desulfurization and denitrification liquid, and thus increasing the desulfurization and denitrification efficiency of the desulfurization and denitrification liquid for the waste gas.

[0037] As a specific embodiment of the present invention, L-shaped grooves 17 are uniformly formed inside the housing 1. The lower ends of the L-shaped grooves 17 communicate with the first grooves 16. A first slider 171 and a second slider 172 are slidably connected in the L-shaped grooves 17. One end of the first slider 171 extends into the first groove 16. The second slider 172 is parallel to the horizontal plane. A return spring is sleeved outside the second slider 172, and one end of the second slider 172 contacts the upper end of the first slider 171. Liquid delivery pipes 18 are fixedly connected to the upper openings of the L-shaped grooves 17. One end of the second slider 172 extends into the liquid delivery pipes 18. Spray heads 181 are uniformly arranged at the lower ends of the liquid delivery pipes 18. A first pipe 19 is arranged at the intersection of the plurality of liquid delivery pipes 18. The lower end of the first pipe 19 communicates with the liquid delivery pipes 18. The upper end of the first pipe 19 passes through the cover body 11 and is located on the upper surface of the cover body 11. A water tank 191 is arranged on the upper surface of the cover body 11. The water tank 191 contains desulfurization and denitrification liquid, and the water tank 191 communicates with the first pipe 19;

[0038] During use, an L-shaped groove 17 is uniformly formed inside the housing 1. A first slider 171 and a second slider 172 are slidably connected inside the L-shaped groove 17, with one end of the first slider 171 extending into the first groove 16. When the motor 12 rotates, the motor 12 drives the driving shaft 2 to rotate, and the driving shaft 2 drives the second plate 24 to rotate. When the second plate 24 rotates, the first convex block 242 and the second convex block 161 are pressed against each other, causing the second plate 24 to vibrate up and down. When the second plate 24 vibrates upward, the second plate 24 presses the first slider 171, and the first slider 171 moves upward. When the first slider 171 slides, it presses the second slider 172, and the second slider 172 is pressed and moves into the interior of the infusion tube 18. The return spring is used to reset the second slider 172 and the first slider 171. When the second slider 172 moves, the desulfurization and denitrification liquid in the water tank 191 flows into the infusion tube 18 through the first tube 19 under the action of its own gravity. The second slider 172 applies hydraulic pressure to the desulfurization and denitrification liquid inside the infusion tube 18, causing the desulfurization and denitrification liquid to spray out from the spray head 181, making the desulfurization and denitrification liquid flow downward in a mist shape to filter the waste gas. When the desulfurization and denitrification liquid descends in a mist shape, the misty liquid causes the gas to flow back downward, providing conditions for secondary filtration of the waste gas, thereby improving the filtration efficiency of the waste gas. And by providing the first tube 19 at the upper end of the infusion tube 18, connecting the upper end of the first tube 19 to the water tank 191 and the lower end of the first tube 19 to communicate with the infusion tube 18, the desulfurization and denitrification liquid inside the water tank 191 flows through the first tube 19 into the interior of the infusion tube 18, so that the interior of the infusion tube 18 is always filled with the desulfurization and denitrification liquid, thus ensuring the continuity of the desulfurization and denitrification liquid.

[0039] As a specific embodiment of the present invention, sector-shaped pieces 245 are uniformly arranged in the through hole 243, and the arc edges of the sector-shaped pieces 245 are hinged to the inner wall of the through hole 243;

[0040] During use, sector pieces 245 are evenly arranged in through hole 243, and the arc-shaped edges of the sector pieces 245 are hinged to the inner wall of the through hole 243. When the motor 12 rotates, the motor 12 drives the driving shaft 2 to rotate, the driving shaft 2 drives the rotating shaft 22 to rotate. When the rotating shaft 22 rotates, through the engagement between the rectangular groove 221 of the rotating shaft 22 and the rectangular block 241 on the second plate 24, the second plate 24 rotates. When the second plate 24 rotates, the first convex block 242 at the lower end of the second plate 24 presses against the second convex block 161 in the first groove 16, so that the second plate 24 vibrates up and down. When the second plate 24 moves downward, the second plate 24 presses the air below, and the gas flows back downward, so that the first filter screen 23 filters the flowing-back gas multiple times, thereby improving the cleanliness of the gas. Moreover, when the second plate 24 presses the gas, the gas generates a reaction force on the second plate 24, causing the middle of the sector piece 245 to open, so that the gas passes through, thereby improving the gas filtration efficiency.

[0041] The specific working process is as follows:

[0042] The desulfurization and denitrification liquid is poured into the inside of the housing 1 through the water inlet pipe 13, so that the liquid level of the desulfurization and denitrification liquid is located at the upper end surface of the driving shaft 2, and at the same time the liquid level is located below the first filter screen 23. Then, waste gas is introduced into the inner wall of the housing 1 through the air inlet pipe 14. Subsequently, the motor 12 is started. When the motor 12 rotates, the motor 12 drives the driving shaft 2 to rotate. When the driving shaft 2 drives the first plate 21 to rotate, the first plate 21 stirs the desulfurization and denitrification liquid inside, making the mixing of the waste gas and the desulfurization and denitrification liquid more uniform. Then, after the waste gas is filtered by the desulfurization and denitrification liquid and continues to be introduced into the inside of the housing 1, the gas after being filtered by the desulfurization and denitrification liquid moves upward. When the filtered gas moves upward, the gas passes through the first filter screen 23, so that the first filter screen 23 filters the dust and impurities in the gas, thereby improving the cleanliness of the gas. And when the motor 12 rotates, the driving shaft 2 rotates, and the driving shaft 2 drives the rotating shaft 22 to rotate. The first filter screen 23 is slidably connected to the rotating shaft 22. When the rotating shaft 22 rotates, the first filter screen 23 does not move. And by providing a rectangular groove 221 on the upper end surface of the rotating shaft 22 and a rectangular block 241 on the lower end surface of the second plate 24, the rectangular block 241 is located in the rectangular groove 221. When the rotating shaft 22 rotates, through the engagement between the rectangular groove 221 and the rectangular block 241, and the second plate 24 is located in the first groove 16 on the inner wall of the housing 1, the side wall of the first groove 16 limits the second plate 24, so that the rotating shaft 22 drives the second plate 24 to rotate. When the second plate 24 rotates, the second plate 24 drives the first convex block 242 at the lower end to move. The contact end of the first convex block 242 and the second convex block 161 is arc-shaped. When the first convex block 242 moves, it presses against the second convex block 161, so that the second plate 24 vibrates up and down. When the second plate 24 vibrates up and down, the second plate 24 squeezes the gas passing through the first filter screen 23, so that the gas passes through the first filter screen 23 again and returns to the lower side of the first filter screen 23. Then the gas passes through the first filter screen 23 again. Through the up and down vibration of the second plate 24, the first filter screen 23 realizes multiple filtration of the gas, and the filtered gas flows to the upper side of the second plate 24 through the through holes 243 on the second plate 24, and then flows out through the air outlet pipe 15.
