When in use, water and medicine are added to the inside of the water tank 17 to mix them into an absorption liquid, and then the water pump 16 is started. The input end of the water pump 16 draws the absorption liquid from the inside of the water tank 17 and transports the absorption liquid to the inside of the spray pipe 15. The spray pipe 15 sprays the absorption liquid through a number of spray holes. Since the ammonia absorbed by the filling layer 14 can only be discharged through the two rectangular air outlets at the upper end of the second baffle 32, it is convenient for the ammonia to combine with the absorption liquid, and the used absorption liquid falls on the upper end of the filling layer 14, and then drips on the upper end of the first partition 19 through the filling layer 14.

[0030] The liquid discharge mechanism includes a floating plate 22, a sliding tube 24 is fixedly provided on the upper end of the floating plate 22, the floating plate 22 and the sliding tube 24 are both slidably provided on a guide slide 43, the guide slide 43 is fixedly provided on the upper end of the liquid blocking slide 20, first guide groove rods 44 are slidably provided on both sides of the liquid blocking slide 20, the first guide groove rods 44 are fixedly provided on the upper end of the first partition 19, a first fixed plate 45 is fixedly provided on one side of the liquid blocking slide 20, a tension spring 21 is provided between one side of the first fixed plate 45 and the inside of the absorption tower body 11, a mounting ring 46 is slidably provided on the sliding tube 24, and the mounting ring An annular mounting groove is provided in the middle of 46, and a magnet ring 25 is fixedly provided in the annular mounting groove. A push plate 26 is symmetrically provided above one end of the sliding tube 24, and the push plate 26 is symmetrically arranged at the bottom end of the sliding plate 28. Second guide groove rods 47 are slidably provided on both sides of the sliding plate 28, and the second guide groove rods 47 are fixedly provided inside the absorption tower body 11. An arc groove is provided at one end of the push plate 26, and a permanent magnet 27 is fixedly provided in the arc groove. The permanent magnet 27 has opposite polarity to the magnet ring 25, and a first driving component for driving the sliding plate 28 to move is provided at the upper end of the sliding plate 28.

[0031] The first driving assembly includes a guide frame 29, which is fixed on the upper end of the sliding plate 28. A sliding column 48 is slidably provided inside the guide frame 29. The sliding column 48 is fixed on the bottom end of the mounting turntable 30. The rotating shaft at the upper end of the mounting turntable 30 is rotatably provided in the mounting hole at the bottom end of the support plate 49. The support plate 49 is fixed inside the absorption tower body 11. A driven wheel is fixed on the rotating shaft at the upper end of the mounting turntable 30. The driven wheel is connected to the driving wheel through a belt. The driving wheel is fixed on one end of the fixed shaft. The fixed shaft is rotatably provided in the mounting hole at the upper end of the support plate 49. The other end of the fixed shaft is fixedly provided with a There is an impeller 31, which is arranged at a position corresponding to one end of the air inlet pipe 12. When in use, when it is necessary to process ammonia, the air inlet pipe 12 is connected with the external air supply component, so that the external air supply component transports ammonia to the inside of the absorption tower body 11 through the air inlet pipe 12. When the ammonia enters the inside of the absorption tower body 11, the airflow drives the impeller 31 to rotate, the impeller 31 drives the fixed shaft to rotate, the fixed shaft drives the installation turntable 30 to rotate, and the installation turntable 30 drives the sliding column 48 to rotate. The sliding column 48 is used in conjunction with the guide frame 29, so that the sliding plate 28 drives the push plate 26 to reciprocate along the length direction of the second guide groove rod 47, and As the used absorption liquid falls on the upper end of the first partition 19, the liquid level on the upper end of the first partition 19 increases. Since the liquid cannot be compressed, the distance between the upper end of the absorption liquid and the bottom end of the filling layer 14 decreases, so that the ammonia gas at the upper end of the first partition 19 and the bottom end of the filling layer 14 is pushed to the upper end of the filling layer 14 for treatment. When the liquid level rises, the floating plate 22 always floats on the upper end of the absorption liquid, so that the floating plate 22 drives the sliding tube 24 and the mounting ring 46 to move. When the mounting ring 46 is aligned with the notch at one end of the push plate 26, the magnet ring 25 and the permanent magnet 27 are attracted to each other, so that the sliding plate 28 passes through the push plate 26 and the sliding tube 2 4 and the guide slide bar 43 push the liquid retaining slide plate 20 to slide. When the liquid retaining slide plate 20 is separated from one end of the drain pipe, the absorption liquid at the upper end of the first partition 19 flows into the water storage chamber. As the liquid level at the upper end of the first partition 19 drops, the floating plate 22 drives the sliding tube 24 to move. Under the action of the magnet ring 25 and the permanent magnet 27, the mounting ring 46 slides on the sliding tube 24. When the mounting ring 46 is tightly attached to the upper end of the sliding tube 24, under the action of the self-weight of the sliding tube 24 and the floating plate 22, the magnet ring 25 is separated from the permanent magnet 27, so that the liquid retaining slide plate 20 no longer moves, and the space between the upper end of the absorption liquid and the bottom end of the filling layer 14 becomes larger.

[0032] The floating plate 22 is fixed with a weight ring 23. When in use, after the upper end of the mounting ring 46 is in close contact with the upper end of the sliding tube 24, the weight ring 23 increases the weight of one end of the sliding tube 24, making it easier to separate the magnet ring 25 from the permanent magnet 27.

[0033] The dewatering mechanism includes a cooling pipe 37, which is arranged at the upper end of the third baffle 33. A rotating hole is provided at the position of the absorption tower body 11 corresponding to the position of the cooling pipe 37. Bearings 50 are fixedly provided at both ends of the cooling pipe 37. The outer rings of the bearings 50 are fixedly provided with mounting pipes 51. The mounting pipes 51 are fixedly provided on the absorption tower body 11. Several air intake fans 38 are fixedly provided inside the cooling pipe 37. Several spacers 52 are fixedly provided on the cooling pipe 37. A sealing plate 36 is fixedly provided at one end of the conveying pipe 34. The sealing plate 36 is fixedly provided at one end of the conveying pipe 34. 6 is arranged outside the spacer 52, the sealing plate 36 is coaxially arranged with the cooling pipe 37, one end of the delivery pipe 34 is sleeved with a fixed pipe 53, the fixed pipe 53 is provided with a heating wire 35, the inside of the absorption tower body 11 is connected with the third baffle 33 and a U-shaped pipe is provided, the output end of the U-shaped pipe is connected with a reflux pipe 41, one end of the reflux pipe 41 is connected with the inside of the water storage tank 17, and one end of the cooling pipe 37 is provided with a second driving component for driving the cooling pipe 37 to rotate. When in use, when it is necessary to defog the ammonia gas, the driving component drives the cooling pipe 37 to rotate. The cooling tube 37 rotates, and when the cooling tube 37 rotates, it drives several air intake fans 38 to rotate, so as to accelerate the air circulation inside the cooling tube 37, so that the overall temperature of the cooling tube 37 drops, and at the same time, the ammonia gas after being sprayed enters the inside of the delivery tube 34. At this time, the heating wire 35 is energized to make the heating wire 35 heat up, thereby heating the ammonia gas, and the heated ammonia gas is discharged through one end of the delivery tube 34. Since a sealing plate 36 is fixed at one end of the delivery tube 34, the ammonia gas enters the dewatering chamber composed of two spacers 52 and the cooling tube 37, so that the cooling tube 37 is heated by the ammonia gas. Condensation is carried out. When the dewatering chamber is separated from one end of the sealing plate 36, the condensed water falls on the upper end of the third baffle plate 33, and the ammonia is discharged after being defogged by the defogger plate 18 again. When the liquid at the upper end of the third baffle plate 33 exceeds the height of the output end of the U-shaped tube, the liquid inside the third baffle plate 33 flows into the water storage tank 17 through the reflux pipe 41. It is worth noting that the water storage tank 17 adopts existing components, and the water storage tank 17 is provided with a concentration sensor, a liquid level sensor, a drain pipe, a liquid adding pipe, a dosing component, etc., so that the concentration of the absorption liquid inside the water storage tank 17 is always kept stable, which will not be repeated here.

[0034] The second driving assembly includes a gear ring 39, which is fixed at one end of the cooling tube 37. A gear is meshed on the gear ring 39, and the gear is fixed at the output end of the motor 40. The motor 40 is fixed on the absorption tower body 11. When in use, when the cooling tube 37 rotates when necessary, the motor 40 is started, and the output end of the motor 40 meshes with the gear ring 39 to drive the cooling tube 37 to rotate.

[0035] A fixed baffle 42 is provided above the cooling tube 37 and fixed inside the absorption tower body 11. The fixed baffle 42 is arranged in an arc shape, which can prevent the liquid from being thrown into the demister plate 18 when the cooling tube 37 rotates.

[0036] The above embodiment discloses an ammonia absorption tower, wherein when ammonia needs to be processed, the air inlet pipe 12 is connected with the external air supply component, so that the external air supply component transports ammonia to the inside of the absorption tower body 11 through the air inlet pipe 12. When ammonia enters the inside of the absorption tower body 11, the airflow drives the impeller 31 to rotate, the impeller 31 drives the fixed shaft to rotate, the fixed shaft drives the installation turntable 30 to rotate, and the installation turntable 30 drives the sliding column 48 to rotate. The sliding column 48 cooperates with the guide frame 29 to make the sliding plate 28 drive the push plate 26 to reciprocate along the length direction of the second guide groove rod 47, and as the used absorption liquid falls on the first partition The upper end of the plate 19 increases the liquid level at the upper end of the first partition 19. Since the liquid cannot be compressed, the distance between the upper end of the absorption liquid and the bottom end of the filling layer 14 is reduced, so that the ammonia gas at the upper end of the first partition 19 and the bottom end of the filling layer 14 is pushed to the upper end of the filling layer 14 for treatment. When the liquid level rises, the floating plate 22 always floats on the upper end of the absorption liquid, so that the floating plate 22 drives the sliding tube 24 and the mounting ring 46 to move. When the mounting ring 46 is aligned with the notch at one end of the push plate 26, the magnet ring 25 and the permanent magnet 27 are mutually attracted, so that the sliding plate 28 pushes the liquid blocking slide plate 20 to slide through the push plate 26, the sliding tube 24 and the guide slide rod 43. When the liquid retaining slide plate 20 is separated from one end of the drain pipe, the absorption liquid at the upper end of the first partition plate 19 flows into the water storage chamber. As the liquid level at the upper end of the first partition plate 19 drops, the floating plate 22 drives the sliding tube 24 to move, and under the action of the magnet ring 25 and the permanent magnet 27, the mounting ring 46 slides on the sliding tube 24. When the mounting ring 46 is in close contact with the upper end of the sliding tube 24, under the action of the deadweight of the counterweight ring 23, the sliding tube 24 and the floating plate 22, the magnet ring 25 is separated from the permanent magnet 27, so that the liquid retaining slide plate 20 no longer moves, and the space between the upper end of the absorption liquid and the bottom end of the filling layer 14 becomes larger, and the ammonia gas after being sprayed enters the delivery pipe 34. Inside, at this time, the heating wire 35 is energized to make the heating wire 35 heat up, thereby heating the ammonia gas, and the heated ammonia gas is discharged through one end of the delivery pipe 34. Since a sealing plate 36 is fixed at one end of the delivery pipe 34, the ammonia gas enters the dewatering chamber composed of two spacers 52 and a cooling pipe 37, so that the cooling pipe 37 condenses the ammonia gas. When the dewatering chamber is separated from one end of the sealing plate 36, the condensed water falls on the upper end of the third baffle plate 33, and the ammonia gas is defogged again by the defogger plate 18 and then discharged. When the liquid at the upper end of the third baffle plate 33 exceeds the height of the output end of the U-shaped tube, the liquid inside the third baffle plate 33 flows into the water storage tank 17 through the reflux pipe 41.

[0037] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
