DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Example 1, reference Figure 1-4A spray assembly of a spray tower includes a spray tower 1, a water tank 2 and a spray rack 3. The water tank 2 and the spray rack 3 are interconnected through a pipeline. A rotating drum 5 is rotatably arranged in the spray tower 1 below the spray rack 3. A plurality of liquid inlets 6 are evenly opened on the outer side of the rotating drum 5. A blocking component 7 and a regulating component 8 are also arranged in the rotating drum 5.

[0026] The regulating component 8 includes a diverter hole 81, a gas input hole 82, a cavity 83 and a connecting chamber 84. The cavity 83 is distributed in a circular array on the inner side of the drum 5. The multiple cavities 83 are interconnected through the connecting chamber 84. The gas input hole 82 is opened at the axial center line position of the drum 5, and one end of the gas input hole 82 is connected to the air intake device through a pipeline. The gas input hole 82 is connected to each cavity 83 through the diverter hole 81, and each cavity 83 corresponds to the liquid inlet 6 one by one.

[0027] The blocking assembly 7 includes a slot 71, a baffle 72 and an electric telescopic rod 73. The slot 71 is opened on the inner side of the cavity 83. The baffle 72 is connected to one end of the electric telescopic rod 73, and the baffle 72 is slidably arranged on the inner side of the slot 71. The positions of the liquid inlet 6 and the slot 71 correspond to each other. The cavity 83 is filled with an absorbent, and the absorbent is specifically activated carbon particles.

[0028] The upper ends of both sides of the spray tower 1 are symmetrically provided with downwardly inclined connecting plates 4 , and the end positions of the two connecting plates 4 are in contact with the outer surface of the rotating drum 5 .

[0029] Activated carbon particles are filled into the inner side of the cavity 83, ammonia enters the gas input hole 82 through the pipeline, and then is transferred to different cavities 83 through the diversion hole 81. After the activated carbon particles adsorb the ammonia, the activated carbon particles have a large surface area and can concentrate on adsorbing the ammonia. The stepper motor 18 is started, and the stepper motor 18 drives the drum 5 to rotate at a low speed inside the spray tower 1. The upper spray rack 3 sprays out sodium hydroxide solution. When the liquid inlet 6 is located at the top and is in an open state, the solution smoothly passes through the liquid inlet 6 and the slot 71 into the cavity 83. At this time, since the drum 5 is in a low-speed rotation process, the activated carbon particles and sodium hydroxide solution in different cavities 83 will flow from the connecting chamber 84 to the lower cavity 83. In this process, the activated carbon particles can roll when transferred, so that the surface of the activated carbon particles that were not in contact with the ammonia due to accumulation can get the opportunity to combine with the ammonia.

[0030] In this process, due to the pore structure on the outer surface of the activated carbon particles, and these pores are large and small, when the pores on the surface of the activated carbon particles are small, it is difficult for the sodium hydroxide solution to enter these pores and react with the adsorbed ammonia. This is because there is surface tension on the surface of the liquid, which makes the surface of the liquid like an elastic film, tending to maintain the minimum surface area. When the gap is small, the effect of surface tension is more significant, which will prevent the liquid from entering the gap.

[0031] To this end, a rotating drum 5 is designed to keep the liquid and the activated carbon particles in an active state, so that during the collision of the activated carbon particles with the solution, the molecular movement inside the liquid can be made more intense, breaking the orderly arrangement of the molecules on the surface of the liquid, thereby reducing the surface tension, allowing the sodium hydroxide solution to smoothly enter the pores of the activated carbon particles and promote the normal occurrence of the reaction.

[0032] Secondly, during the rotation of the drum 5, each rotation is a cycle. During this cycle, the cavity 83 located below will contain more activated carbon particles and sodium hydroxide solution. In order to allow these sodium hydroxide solutions and activated carbon particles to remain smoothly in the cavity 83, when the cavity 83 is about to rotate to the bottom, the electric telescopic rod 73 will be controlled to extend, and the baffle 72 will be used to block the slot 71. In this way, the material will not overflow from the liquid inlet 6. At the same time, the two electric telescopic rods 73 at the upper end will shrink, and the baffle 72 will be removed from the slot 71, so that the sodium hydroxide solution above can smoothly enter the cavity 83 from the liquid inlet 6. When the liquid inlet 6 moves to the position of the connecting plate 4, the sodium hydroxide solution accumulated between the outer surface of the drum 5 and the connecting plate 4 will smoothly enter the cavity 83 from the liquid inlet 6 with the help of the slope of the connecting plate 4. The purpose of adding the reactant sodium hydroxide in small amounts and multiple times is to allow the reactants to fully contact and react in the reaction system, improve the utilization rate of the raw materials, and reduce the unreacted raw material residues.

[0033] Example 2, reference Figure 1-6 The difference between this embodiment and embodiment 1 is that a discharge port 9 is installed on one side of the spray tower 1, a liquid output pipe 19 is arranged at the bottom position of the spray tower 1, and a receiving plate 11 is movably arranged on the inner side of the spray tower 1, one end of the receiving plate 11 matches the position of the discharge port 9, a plurality of arc plates 12 are arranged on the receiving plate 11, and penetrating water leakage holes 13 are opened on the receiving plate 11 at the lower end of the arc plate 12, and partitions 10 are symmetrically arranged at the position of the receiving plate 11 near the discharge port 9, and are located between the two partitions 10.

[0034] A chassis 14 is installed outside the spray tower 1, a stepper motor 18 is installed inside the chassis 14, and one end of the output shaft of the stepper motor 18 is connected to the drum 5, and a transmission member is also arranged on the output shaft of the stepper motor 18.

[0035] The transmission member includes a first transmission tooth 15, a chain 16, a second transmission tooth 17 and a round rod 22. The first transmission tooth 15 is installed on the output shaft of the stepper motor 18, the round rod 22 is installed on the spray tower 1, the second transmission tooth 17 is installed at one end of the round rod 22, the chain 16 is sleeved on the outside of the second transmission tooth 17 and the first transmission tooth 15, and the other end of the round rod 22 extends to the inside of the spray tower 1.

[0036] When the reaction is completed, it is necessary to collect the material in the cavity 83. At this time, the electric telescopic rod 73 is adjusted to a shortened state so that the liquid inlet 6 is in an open state. As the drum 5 continues to rotate, all the materials inside the cavity 83 can fall down, and the fallen materials will fall on the receiving plate 11. Since the activated carbon particles can roll on the receiving plate 11, the activated carbon particles can be collected from the discharge port 9. At this time, the fallen liquid can fall from the leakage hole 13 and be discharged from the liquid output pipe 19 for centralized collection. The position of the leakage hole 13 partially extends to the outside of the arc plate 12. In this way, the liquid can be well collected through the leakage hole 13, and the arc plate 12 can be well utilized to prevent the activated carbon particles from entering the leakage hole 13.

[0037] Example 3, reference Figure 5-6 The difference between this embodiment and Embodiment 1 and Embodiment 2 is that a swing assembly is arranged between the end position of the round rod 22 inside the spray tower 1 and the receiving plate 11, and the swing assembly includes a first connecting rod 20 and a second connecting rod 21. The first connecting rod 20 is arranged at the end position of the round rod 22, and the second connecting rod 21 is hinged between the first connecting rod 20 and the receiving plate 11 through a hinge column. When the first connecting rod 20 rotates, there is a gap between the first connecting rod 20 and the rotating drum 5 above.

[0038] Due to the porous nature of the surface of activated carbon particles, part of the liquid will remain on its surface, and the liquid on the surface needs to be separated.

[0039] To this end, in order to separate the liquid on the surface of the activated carbon particles, the activated carbon particles need to move more violently when rolling on the receiving plate 11, and the first connecting rod 20 rotates together with the round rod 22. At this time, the first connecting rod 20 will drive the second connecting rod 21 to perform reciprocating lifting and lowering motions in the longitudinal direction. The rocker structure composed of the first connecting rod 20, the second connecting rod 21 and the round rod 22 will make the receiving plate 11 always in an up and down swinging state, so as to make the activated carbon particles move more violently. At the same time, the setting of the arc plate 12 can allow the activated carbon particles to get the opportunity to roll and jump, and separate the liquid on their surface during the repeated leaps and collisions.

[0040] The working principle of the device is: Activated carbon particles are filled into the inner side of the cavity 83, ammonia enters the gas input hole 82 through the pipeline, and then is transferred to different cavities 83 through the diversion hole 81. After the activated carbon particles adsorb the ammonia, the activated carbon particles have a large surface area and can concentrate on adsorbing the ammonia. The stepper motor 18 is started, and the stepper motor 18 drives the drum 5 to rotate at a low speed inside the spray tower 1. The upper spray rack 3 sprays out sodium hydroxide solution. When the liquid inlet 6 is located at the top and is in an open state, the solution smoothly passes through the liquid inlet 6 and the slot 71 into the cavity 83. At this time, since the drum 5 is in a low-speed rotation process, the activated carbon particles and sodium hydroxide solution in different cavities 83 will flow from the connecting chamber 84 to the lower cavity 83. In this process, the activated carbon particles can roll when transferred, so that the surface of the activated carbon particles that were not in contact with the ammonia due to accumulation can get the opportunity to combine with the ammonia.

[0041] In this process, due to the pore structure on the outer surface of the activated carbon particles, and these pores are large and small, when the pores on the surface of the activated carbon particles are small, it is difficult for the sodium hydroxide solution to enter these pores and react with the adsorbed ammonia. This is because there is surface tension on the surface of the liquid, which makes the surface of the liquid like an elastic film, tending to maintain the minimum surface area. When the gap is small, the effect of surface tension is more significant, which will prevent the liquid from entering the gap.

[0042] To this end, a rotating drum 5 is designed to keep the liquid and the activated carbon particles in an active state, so that during the collision of the activated carbon particles with the solution, the molecular movement inside the liquid can be made more intense, breaking the orderly arrangement of the molecules on the surface of the liquid, thereby reducing the surface tension, allowing the sodium hydroxide solution to smoothly enter the pores of the activated carbon particles and promote the normal occurrence of the reaction.

[0043] Secondly, during the rotation of the drum 5, each rotation is a cycle. During this cycle, the cavity 83 located below will contain more activated carbon particles and sodium hydroxide solution. In order to allow these sodium hydroxide solutions and activated carbon particles to remain smoothly in the cavity 83, when the cavity 83 is about to rotate to the bottom, the electric telescopic rod 73 will be controlled to extend, and the baffle 72 will be used to block the slot 71. In this way, the material will not overflow from the liquid inlet 6. At the same time, the two electric telescopic rods 73 at the upper end will shrink, and the baffle 72 will be removed from the slot 71, so that the sodium hydroxide solution above can smoothly enter the cavity 83 from the liquid inlet 6. When the liquid inlet 6 moves to the position of the connecting plate 4, the sodium hydroxide solution accumulated between the outer surface of the drum 5 and the connecting plate 4 will smoothly enter the cavity 83 from the liquid inlet 6 with the help of the slope of the connecting plate 4. The purpose of adding the reactant sodium hydroxide in small amounts and multiple times is to allow the reactants to fully contact and react in the reaction system, improve the utilization rate of the raw materials, and reduce the unreacted raw material residues.

[0044] When the reaction is completed, it is necessary to collect the material in the cavity 83. At this time, the electric telescopic rod 73 is adjusted to a shortened state so that the liquid inlet 6 is in an open state. As the drum 5 continues to rotate, all the materials inside the cavity 83 can fall down, and the fallen materials will fall on the receiving plate 11. Since the activated carbon particles can roll on the receiving plate 11, the activated carbon particles can be collected from the discharge port 9. At this time, the fallen liquid can fall from the leakage hole 13 and be discharged from the liquid output pipe 19 for centralized collection. The position of the leakage hole 13 partially extends to the outside of the arc plate 12. In this way, the liquid can be well collected through the leakage hole 13, and the arc plate 12 can be well utilized to prevent the activated carbon particles from entering the leakage hole 13.

[0045] Due to the porous nature of the surface of activated carbon particles, part of the liquid will remain on its surface, and the liquid on the surface needs to be separated.

[0046] To this end, in order to separate the liquid on the surface of the activated carbon particles, the activated carbon particles need to move more violently when rolling on the receiving plate 11, and the first connecting rod 20 rotates together with the round rod 22. At this time, the first connecting rod 20 will drive the second connecting rod 21 to perform reciprocating lifting and lowering motions in the longitudinal direction. The rocker structure composed of the first connecting rod 20, the second connecting rod 21 and the round rod 22 will make the receiving plate 11 always in an up and down swinging state, so as to make the activated carbon particles move more violently. At the same time, the setting of the arc plate 12 can allow the activated carbon particles to get the opportunity to roll and jump, and separate the liquid on their surface during the repeated leaps and collisions.
