Description

Technical Field

[0001] This invention relates to the technical field of ammonia treatment, and in particular to an ammonia treatment and recovery device. Background Technology

[0002] Ammonia is a colorless gas with a pungent, irritating odor. It is gaseous at room temperature and is highly soluble in water. As a pollutant whose emission limits are set by national regulations, ammonia causes environmental pollution by: disrupting air quality; altering the pH of water bodies and increasing ammonia nitrogen levels; causing soil salinization; being toxic; and being corrosive.

[0003] Chinese patent CN115738705A discloses a water-sealed tower-type positive pressure ammonia capture and recovery system, comprising two exhaust fans connected by pipelines, a negative pressure tank, a water-sealed tower, a circulation pump, a makeup water pump, an ammonia water transfer pump, an ammonia water storage tank, a fresh water tank, a distribution bed, an air flow shut-off device, a ship's main and auxiliary engine SCR system, and an ammonia water treatment pump. This invention's water-sealed tower-type positive pressure ammonia capture and recovery system uses fans to blow ammonia gas remaining in pipelines or leaking from the system into the water-sealed tower. Through a three-stage progressive water-soluble absorption method, the ammonia gas contained in the mixed gas is completely absorbed. The circulation pump, makeup water pump, and various instruments ensure the system's safety, efficiency, and controllability. After the ammonia gas is absorbed and converted into ammonia water of a certain concentration, it can be stored in a dedicated cabinet for use in the ship's main and auxiliary engine SCR systems to reduce NOx emissions from the exhaust system, achieving ammonia capture, recovery, and reuse, ultimately reaching the standard of zero ammonia emissions.

[0004] Chinese patent CN203315978U discloses a membrane-based ammonia treatment and recovery device, including a pre-treatment component and an ammonia absorption component. The ammonia absorption component includes a membrane element, an ammonia water storage tank, an ammonia water pipeline heat exchanger, a circulating pump, and a pressure reducing valve. The membrane element includes an air inlet, an air outlet, a water outlet, and a water inlet. The key feature is that the ammonia absorption component has at least two stages. The beneficial effects of this membrane-based ammonia treatment and recovery device and process are: after ammonia is treated by a multi-stage membrane device, the tail gas can meet emission standards, while maintaining the recovered ammonia water concentration at a high level, above 20%; the absorbent can be recycled and reused in process production or sold as a chemical product after the concentration is increased.

[0005] The aforementioned technologies have the following drawbacks: the treatment method for ammonia is relatively simple, and it does not combine water-sealed tower and membrane treatment methods. Furthermore, when using water-sealed towers to treat ammonia, the ammonia rises rapidly inside the treatment liquid, which results in the treatment liquid not being able to fully absorb the ammonia. Summary of the Invention

[0006] To address the problems mentioned in the background art, the present invention provides an ammonia treatment and recovery device.

[0007] The present invention provides an ammonia treatment and recovery device, which adopts the following technical solution: it includes a high-pressure treatment tank and a spray frame. The spray frame is installed inside the high-pressure treatment tank. A membrane treatment tank is arranged outside the high-pressure treatment tank. A vent pipe is installed in connection with the membrane treatment tank. The other end of the vent pipe passes through the outside of the high-pressure treatment tank and is coaxially and vertically arranged inside the high-pressure treatment tank. Multiple double-cylinder components are installed inside the high-pressure treatment tank. The multiple double-cylinder components are equally spaced and coaxially arranged with the vertical end of the vent pipe.

[0008] Each twin-cylinder assembly has multiple layers of fixed ring plates installed on its outer ring side. Each fixed ring plate has a movable ring plate in contact with its upper side. The outer ring surface of the movable ring plate slides in contact with the inner ring surface of the adjacent outer twin-cylinder assembly. The vertical part of the vent pipe is equipped with a power component that controls the rotation of the twin-cylinder assembly and the movable ring plate.

[0009] The air outlet of the vent pipe is located on the lower side of the twin-cylinder assembly.

[0010] Optionally, the dual-cylinder assembly includes an inner cylinder and an outer cylinder, with the inner cylinder rotatably inserted into the inner side of the outer cylinder. Both the outer cylinder and the inner cylinder have multiple through holes, which are evenly distributed in multiple rows on the outer side of the outer cylinder and the inner cylinder. The through holes distributed on the surfaces of the outer cylinder and the inner cylinder are circumferentially staggered.

[0011] The upper ends of both the inner and outer cylinders are connected to the power assembly. The fixed ring plate is fixed to the outer ring surface of the outer cylinder on the adjacent inner side. The inner ring surface of the inner cylinder is in sliding contact with the movable ring plate on the adjacent inner side. The inner ring surface of the high-pressure treatment tank is in sliding contact with the movable ring plate on the adjacent inner side.

[0012] Optionally, the power assembly includes a power box, a transmission ring frame, and a misaligned ring frame. The upper ends of the inner and outer cylinders are fixed to the transmission ring frame and the misaligned ring frame, respectively. The misaligned ring frame is rotatably sleeved on the outside of the transmission ring frame and can elastically twist relative to the transmission ring frame. The transmission ring frame is rotatably sleeved on the outside of the vertical part of the vent pipe. The power box is installed on the outside of the vertical part of the vent pipe and drives the transmission ring frame to rotate.

[0013] Optionally, a lifting mechanism connected to the movable ring plate is installed on the inner side of the high-pressure treatment tank. The power component drives the double-cylinder assembly to rotate, and the lifting mechanism drives the multiple layers of the movable ring plate to move back and forth up and down.

[0014] Optionally, the lifting mechanism includes an arc-shaped block and multiple suspension frames. The misaligned ring frame is slidably sleeved on the outside of the suspension frame. The suspension frame moves elastically relative to the misaligned ring frame. A round rod is installed at one end of the vertical part of the suspension frame away from the vent pipe. The arc-shaped block is installed inside the high-pressure treatment tank.

[0015] The number of fixed ring plates connected to each outer cylinder is the same as the number of suspension brackets. Each suspension bracket is fixed to the movable ring plate of each layer, and the suspension bracket is slidably connected to the adjacent movable ring plate.

[0016] Optionally, the outer ring surface of the transmission ring frame is provided with a fan-shaped ring groove, and a sliding slider is inserted into the inner side of the fan-shaped ring groove. The slider is fixed to the misaligned ring frame.

[0017] Optionally, the fixed ring plate is a conical cylindrical structure with a large diameter end at the top, and the movable ring plate is a conical cylindrical structure with a small diameter end at the top. The inner diameter of the small diameter end of the movable ring plate is smaller than the inner diameter of the large diameter end of the fixed ring plate, and the fixed ring plates distributed on the outer side of the same outer cylinder are equally spaced vertically.

[0018] Optionally, the axis of the round rod intersects perpendicularly with the axis of the inner cylinder, and multiple suspension brackets are evenly distributed in a circumferential array around the axis of the inner cylinder.

[0019] Optionally, it also includes an air distribution bed installed at the air outlet end of the vent pipe. The air distribution bed is located on the lower side of the twin-cylinder assembly. The air distribution bed has a through hole running vertically through it, and the upper surface of the air distribution bed has a vent hole communicating with the interior.

[0020] Optionally, the spray frame is located above the dual-cylinder assembly and is used to spray the treatment liquid downwards. There is at least one membrane treatment tank, which is connected in series with the vent pipe via a pipeline.

[0021] In summary, the present invention has the following beneficial technical effects:

[0022] 1. This invention, through the coordinated arrangement of a fixed ring plate, a movable ring plate, and a double-cylinder assembly, uses a power assembly to control the lifting mechanism and adjust the relative position of the fixed ring plate and the lower movable ring plate. When the fixed ring plate and the movable ring plate are in contact, they block the ammonia gas below, allowing the ammonia gas to fully react inside the treatment liquid. When the fixed ring plate and the movable ring plate separate, the ammonia gas continues to move upward, increasing the ammonia gas treatment time.

[0023] 2. This invention, through the coordination of components such as arc-shaped blocks, round rods, and suspension frames, allows multiple round rods to rotate around the inner cylinder axis. As the round rods slide on the upper surface of the arc-shaped blocks, the corresponding suspension frames pull the corresponding movable ring plates of the same layer upward. As the multiple round rods slide sequentially on the upper surface of the arc-shaped blocks, they drive the multi-layer movable ring frames to move upward sequentially, causing the ammonia gas to float upward sequentially. This allows the ammonia gas between the inner and outer cylinders to be absorbed and treated in multiple layers, increasing the absorption effect.

[0024] 3. This invention, by setting a fan-shaped annular groove and a slider, allows the misaligned ring frame to rotate relative to the transmission ring frame when the round rod encounters resistance after contacting the arc-shaped block. This causes the slider to slide from one end of the fan-shaped annular groove to the other end, aligning the through holes between the inner and outer cylinders. This allows the treatment liquids on both sides of the inner and outer cylinders to communicate and mix, ensuring a uniform distribution of residual agents on the inner side of the treatment liquid. After the round rod separates from the arc-shaped block, the slider returns to one end of the fan-shaped annular groove under the elastic torsion of the misaligned ring frame and the transmission ring frame, causing the through holes on the surfaces of the inner and outer cylinders to realign.

[0034] The following is in conjunction with the appendix Figures 1-8 The present invention will be described in further detail below.

[0035] This invention discloses an ammonia treatment and recovery device. For example... Figures 1-8As shown, the system includes a high-pressure treatment tank 1 and a spray frame 2. The spray frame 2 is installed inside the high-pressure treatment tank 1 and is connected to an external liquid storage tank. The spray frame 2 is located above the twin-cylinder assembly 4 and is used to spray the treatment liquid downwards. The spray frame 2 can spray the treatment mist downwards. A membrane treatment tank 3 is installed outside the high-pressure treatment tank 1. The membrane treatment tank 3 is filled with a treatment membrane. Both ends of the membrane treatment tank 3 can be disassembled to replace the internal membrane structure. After the gas passes through the membrane treatment tank 3, the internal ammonia gas is initially absorbed. There is at least one membrane treatment tank 3, which is connected in series with a vent pipe 7 through a pipeline. Multiple membrane treatment tanks 3 can be installed as needed. Multi-layer absorption is performed. A vent pipe 7 is installed in the membrane treatment tank 3. The other end of the vent pipe 7 passes through the outside of the high-pressure treatment tank 1 and is coaxially and vertically installed inside the high-pressure treatment tank 1. Both the high-pressure treatment tank 1 and the membrane treatment tank 3 are connected to external high-pressure equipment, which can control the pressure inside the high-pressure treatment tank 1 and the membrane treatment tank 3. By controlling the pressure inside the high-pressure treatment tank 1, the gas absorption efficiency is controlled. Multiple double-cylinder components 4 are installed inside the high-pressure treatment tank 1. The multiple double-cylinder components 4 are equally spaced and coaxially installed with the vertical end of the vent pipe 7. By changing the material of the membrane inside the membrane treatment tank 3, the absorption efficiency of ammonia can be controlled.

[0036] The dual-cylinder assembly 4 includes an inner cylinder 41 and an outer cylinder 42. The inner cylinder 41 is rotatably inserted into the inner side of the outer cylinder 42. Both the outer cylinder 42 and the inner cylinder 41 are provided with multiple through holes. The multiple through holes are evenly distributed in multiple rows on the outer side of the outer cylinder 42 and the inner cylinder 41. The through holes distributed on the surface of the outer cylinder 42 and the inner cylinder 41 are circumferentially staggered. When the through holes between the inner cylinder 41 and the outer cylinder 42 are staggered, the space between the inner side of the inner cylinder 41 and the outer side of the outer cylinder 42 is separated. When the through holes between the inner cylinder 41 and the outer cylinder 42 are connected, the space between the inner side of the inner cylinder 41 and the outer side of the outer cylinder 42 is connected, so that the reaction liquids on the inner and outer sides are connected and mixed together.

[0037] Each double-cylinder assembly 4 has multiple layers of fixed ring plates 8 installed on its outer ring side. Each fixed ring plate 8 has a movable ring plate 9 in contact with its upper side. The outer ring surface of the movable ring plate 9 slides in contact with the inner ring surface of the adjacent outer double-cylinder assembly 4. When the lower side of the movable ring plate 9 contacts the upper end of the fixed ring plate 8, it blocks the ammonia gas on the lower side of the movable ring plate 9 and the fixed ring plate 8 in contact with it, so that the ammonia gas can be fully mixed with the reaction liquid. After the movable ring plate 9 separates upward from the corresponding fixed ring plate 8, the ammonia gas blocked on the lower side can continue to float upward, so that the new ammonia gas on the lower side can move upward. The vertical part of the vent pipe 7 is equipped with a power component 6 that controls the rotation of the double-cylinder assembly 4 and the movable ring plate 9.

[0038] The upper ends of the inner cylinder 41 and the outer cylinder 42 are both connected to the power assembly 6. The fixed ring plate 8 is fixed to the outer ring surface of the adjacent inner outer cylinder 42. The innermost fixed ring plate 8 is fixed to the innermost outer cylinder 42. The inner ring surface of the inner cylinder 41 is in sliding contact with the adjacent inner movable ring plate 9. The inner ring surface of the high-pressure treatment tank 1 is in sliding contact with the adjacent inner movable ring plate 9. The outermost movable ring plate 9 is in sliding contact with the inner wall of the high-pressure treatment tank 1.

[0039] The fixed ring plate 8 is a conical cylindrical structure with a large diameter end at the top, and the movable ring plate 9 is a conical cylindrical structure with a small diameter end at the top. The inner diameter of the small diameter end of the movable ring plate 9 is smaller than the inner diameter of the large diameter end of the fixed ring plate 8. The fixed ring plates 8 distributed on the outer side of the same outer cylinder 42 are equally spaced vertically, so that a closed space is formed between the bottom of the movable ring plate 9 and the top of the fixed ring plate 8. After the movable ring plate 9 separates from the fixed ring plate 8 on the lower side, a reciprocating and bending flow channel is formed between the movable ring plate 9 and the fixed ring plate 8, which further increases the flow trajectory as the ammonia floats upward.

[0040] The power assembly 6 includes a power box 61, a transmission ring frame 62, and a misaligned ring frame 63. The upper ends of the inner cylinder 41 and the outer cylinder 42 are fixed to the transmission ring frame 62 and the misaligned ring frame 63, respectively. The misaligned ring frame 63 is rotatably sleeved on the outside of the transmission ring frame 62. The misaligned ring frame 63 can elastically twist relative to the transmission ring frame 62. The misaligned ring frame 63 and the transmission ring frame 62 are connected by a torsion spring. The transmission ring frame 62 is rotatably sleeved on the outside of the vertical part of the vent pipe 7. The power box 61 is installed on the outside of the vertical part of the vent pipe 7. The power box 61 drives the transmission ring frame 62 to rotate.

[0041] The high-pressure treatment tank 1 is equipped with a motor that provides power to the power box 61. Inside the power box 61, there is a meshing bevel gear transmission assembly that transmits the motor's power to the transmission ring frame 62 for rotational power.

[0042] The outer ring surface of the transmission ring frame 62 is provided with a fan-shaped ring groove 621. A sliding slider 622 is inserted into the inner side of the fan-shaped ring groove 621. The slider 622 is fixed to the misaligned ring frame 63. The elasticity between the misaligned ring frame 63 and the transmission ring frame 62 has a tendency to push the slider 622 to one end of the fan-shaped ring groove 621. At this time, the through holes between the inner cylinder 41 and the outer cylinder 42 are circumferentially misaligned. When the misaligned ring frame 63 drives the slider 622 to move to the other end of the fan-shaped ring groove 621, the through holes between the inner cylinder 41 and the outer cylinder 42 are connected, and the reaction liquids on the inner and outer sides are mixed.

[0043] The high-pressure treatment tank 1 is equipped with a lifting mechanism 5 connected to the movable ring plate 9. The power component 6 drives the double cylinder assembly 4 to rotate, and the lifting mechanism 5 drives the multi-layer movable ring plate 9 to move up and down reciprocally.

[0044] The lifting mechanism 5 includes an arc-shaped block 51 and multiple suspension frames 52. The misaligned ring frame 63 is slidably sleeved on the outside of the suspension frame 52. The suspension frame 52 moves elastically relative to the misaligned ring frame 63. The suspension frame 52 and the connected misaligned ring frame 63 are connected by a vertically arranged elastic telescopic rod, which has the tendency to pull the suspension frame 52 downward. A round rod 53 is installed at one end of the vertical part of the suspension frame 52 away from the vent pipe 7. The arc-shaped block 51 is installed inside the high-pressure treatment tank 1.

[0045] The number of fixed ring plates 8 connected to each outer cylinder 42 is the same as the number of suspension brackets 52. Each suspension bracket 52 is fixed to the movable ring plate 9 of each layer, and the suspension bracket 52 is slidably connected to the adjacent movable ring plate 9.

[0046] The axis of the round rod 53 intersects perpendicularly with the axis of the inner cylinder 41, and multiple suspension brackets 52 are evenly distributed in a circular array around the axis of the inner cylinder 41.

[0047] As the transmission ring frame 62 rotates, the misalignment ring frame 63 rotates along with it through the elastic connection between the transmission ring frame 62 and the transmission ring frame 62. When the round rod 53 comes into contact with the arc block 51 and encounters resistance, the misalignment ring frame 63 rotates relative to the transmission ring frame 62, causing the slider 622 to slide from one end of the fan-shaped ring groove 621 to the other end, so that the through holes between the inner cylinder 41 and the outer cylinder 42 coincide. After the round rod 53 separates from the arc block 51, the slider 622 returns to one end of the fan-shaped ring groove 621 under the elastic torsion of the misalignment ring frame 63 and the transmission ring frame 62, so that the through holes on the surfaces of the inner cylinder 41 and the outer cylinder 42 are misaligned again.

[0048] Simultaneously, when the round rod 53 moves from the lower side of the arc-shaped block 51 to the upper surface of the arc-shaped block 51, it pushes the corresponding suspension bracket 52 to move upward, causing the corresponding connected layer of movable ring plate 9 to move upward and separate from the corresponding fixed ring plate 8. The multiple round rods 53 move sequentially to the upper side of the arc-shaped block 51, and through the corresponding suspension bracket 52, they drive the movable ring plates 9 of different heights to move upward, causing the ammonia gas on the lower side to move upward sequentially.

[0049] The lower end of the vent pipe 7 is connected to an exhaust distribution bed 10, which is located below the twin-cylinder assembly 4.

[0050] The gas distribution bed 10 has a through hole running vertically through it. The upper surface of the gas distribution bed 10 has a vent hole that communicates with the interior. Ammonia gas in the vent pipe 7 is introduced into the reaction liquid in the high-pressure treatment tank 1 through the gas distribution bed 10. A drain pipe is installed at the bottom of the high-pressure treatment tank 1 so that the reaction liquid in the high-pressure treatment tank 1 can be discharged through the drain pipe. A liquid replenishment pipe is installed inside the high-pressure treatment tank 1 on the upper side of the misaligned ring frame 63 and the transmission ring frame 62. The treatment liquid is added to the interior through the liquid replenishment pipe.

[0051] The working principle is as follows: The gas to be treated is filled into the membrane treatment tank 3, where it undergoes preliminary treatment. The pre-treated gas is then ejected from the outlet distribution bed 10 through the vent pipe 7 and enters the treatment liquid inside the high-pressure treatment tank 1. The treatment liquid further treats the gas, and the upward-floating gas enters between the double-cylinder components 4. The power component 6 drives the double-cylinder components 4, the movable ring plate 9, and the fixed ring plate 8 to rotate, mixing the treatment liquid and the gas, increasing the circumferential movement distance of the gas, and increasing the degree of gas absorption. At the same time, the power component 6 drives the multi-layer movable ring plate 9 to move up and down reciprocally through the lifting mechanism 5. When the fixed ring plate 8 contacts the lower movable ring plate 9, the fixed ring plate 8 and the movable ring plate 9 block the ammonia gas below, allowing the ammonia gas to fully react inside the treatment liquid. After the fixed ring plate 8 and the movable ring plate 9 are separated by the lifting mechanism 5, the ammonia gas continues to move upward, increasing the ammonia gas treatment time and the ammonia gas absorption effect.

[0052] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
