Description

Technical Field

[0001] This invention relates to the field of automotive urea wastewater treatment technology, specifically to an automotive urea wastewater treatment device with an integrated cyclone plate and wire mesh demisting structure. Background Technology

[0002] With increasingly stringent national emission standards for diesel vehicles, selective catalytic reduction (SCR) technology has become the mainstream solution for diesel vehicle exhaust treatment. As an essential consumable for reducing nitrogen oxides in SCR technology, the demand for automotive urea solution continues to grow. The production and use of automotive urea generates various types of wastewater, including cooling water, washing water, process wastewater, and equipment cleaning wastewater. Direct discharge of these wastewaters without treatment will pollute the environment.

[0003] Currently, the treatment of automotive urea wastewater generally requires the addition of chemical agents to the reaction chamber via a dosing mechanism to adjust the pH value or remove specific pollutants. Existing dosing mechanisms mostly use a fixed cylinder to deliver the agents into the reaction chamber. After the agents are discharged from the end of the cylinder, they typically concentrate in the central area of ​​the reaction chamber, making it difficult to distribute them evenly to the central and peripheral areas. This affects the sufficient contact between the chemical agents and the wastewater, and the reaction efficiency. Furthermore, the reaction chamber lacks effective auxiliary stirring methods, and the mixing effect between the chemical agents and the wastewater needs improvement.

[0004] Therefore, in order to address the above problems, a vehicle urea wastewater treatment device with an integrated swirl plate and wire mesh demisting structure is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a vehicle urea wastewater treatment device with an integrated swirl plate and wire mesh demisting structure.

[0006] The objective of this invention is achieved through the following technical solution: A vehicle urea wastewater treatment device integrating a swirl plate and wire mesh combined demisting structure, comprising: a multi-stage treatment system, the multi-stage treatment system including a filtration device, a reaction chamber, a reverse osmosis device and a discharge pool, the reaction chamber being provided with a dosing mechanism and a demisting mechanism, the dosing mechanism including a feed pipe and a sleeve penetrating into the reaction chamber, the sleeve being provided with a spiral conveying mechanism, and also including a movable cylinder located in the reaction chamber, the end of the movable cylinder being provided with a clearance groove, the movable cylinder being rotatably connected to the sleeve through the clearance groove, and a steel guide rope extending out of the reaction chamber being pulled on the movable cylinder;

[0007] A rotating ring is rotatably connected to the top of the sleeve. A steel guide rope is wound around the rotating ring. A pressure column is fixedly connected to the edge of the rotating ring. A rotating assembly with elastic elements is fixedly connected to the screw conveyor mechanism. A lifting plate is fixedly connected to the outer surface of the sleeve.

[0008] The rotating component acts as a pressure column, driving the rotating ring to wind up the steel guide rope. When the rotating component contacts the lifting plate, it passes over the pressure column, causing the rotating ring to rotate. By intermittently pushing the pressure column with the rotating component, the rotating ring alternates between winding and releasing the steel guide rope, thereby driving the movable cylinder to continuously oscillate at a small angle within the reaction chamber. This process requires no additional motor or cylinder, resulting in a compact structure and low energy consumption.

[0009] As a further description of the above technical solution:

[0010] The movable cylinder and sleeve are located at the top of the reaction chamber. A motor is fixedly connected to the outer surface of the reaction chamber, and the output shaft of the motor is fixedly connected to the central shaft of the screw conveyor mechanism.

[0011] The feed pipe is connected and fixed to the sleeve. The steel guide rope passes through the feed pipe. When the steel guide rope moves back and forth with the swinging cylinder inside the feed pipe, it will continuously and slightly disturb and move the chemical agent inside the feed pipe, promoting the smooth falling of the chemical agent into the sleeve, and playing an additional function of assisting the feeding.

[0012] A sealing block is fixedly connected between the feed pipe and the reaction chamber. The steel guide rope passes through the sealing block, and the sealing block forms an effective dynamic sealing structure at the point where the steel guide rope exits, preventing high-temperature flue gas and fly ash in the reaction chamber from leaking outward along the gap between the steel guide rope and the pipe wall. At the same time, the sealing block also supports and guides the steel guide rope, reducing direct friction and wear between the steel guide rope and the metal edges of the feed pipe and the reaction chamber shell during reciprocating motion, thus extending the service life of the steel guide rope.

[0013] The swivel ring has a winding groove for winding the steel guide rope. A pressure rod that cooperates with the swivel ring is fixedly connected to the outer surface of the sleeve. The pressure rod restricts the steel guide rope, and the winding groove provides a clear winding trajectory for the steel guide rope, so that the steel guide rope can be orderly embedded in the groove when the swivel ring rotates, avoiding the steel guide rope from being randomly piled up or tangled on the surface of the swivel ring. The pressure rod fits against the edge of the swivel ring, playing a limiting and guiding role, preventing the steel guide rope from coming out of the winding groove during winding or releasing, and ensuring the stability and reliability of the steel guide rope winding and releasing action.

[0014] A pressure ball is fixedly connected to the pressure rod and located in the winding groove. The pressure ball presses against the steel guide rope and extends into the winding groove to apply elastic or constant pressure to the steel guide rope, so that the steel guide rope can fit tightly against the bottom of the winding groove when winding, preventing the phenomenon of jumping out of the groove or tangling due to the loosening or vibration of the steel guide rope.

[0015] The rotating assembly includes a fixed plate and a pressure plate. A rod is fixedly connected to the pressure plate and inserted into the fixed plate. The elastic element is a compression spring, with both ends of the elastic element connected to the fixed plate and the pressure plate respectively. The pressure plate is inserted into the fixed plate through the rod, forming a precisely guided telescopic sliding pair. This ensures that the pressure plate can stably move away from the rotating ring along a straight trajectory when it is squeezed by the wedge-shaped surface of the lifting plate, without swaying or jamming.

[0016] The lifting plate has a wedge-shaped structure at its end. The wedge-shaped structure allows the pressure plate to move away from the rotating ring and pass over the pressure column. The wedge-shaped structure converts the circular motion of the pressure plate into an axial translational motion away from the rotating ring, thus achieving a smooth obstacle crossing without contact.

[0017] A fixed rod is fixedly connected inside the reaction chamber, and a movable shaft is rotatably connected to the end of the fixed rod. A steel guide rope passes through the movable shaft. The movable shaft provides a turning support point for the steel guide rope to travel a long distance inside the reaction chamber, making the direction of the steel guide rope more reasonable and preventing the steel guide rope from hanging randomly inside the reaction chamber and directly contacting the reaction chamber wall.

[0018] A reinforcing plate is fixedly connected to the movable cylinder. The rotating connecting shaft of the sleeve and the movable cylinder is rotatably connected to the reinforcing plate. The reinforcing plate increases the connection rigidity and contact area between the movable cylinder and the rotating connecting shaft, so that the connection part is not prone to deformation or cracking under the dual action of the gravity load of the internal chemical agent and the traction force of the steel guide rope, thereby improving the structural stability and load-bearing capacity of the movable cylinder during reciprocating swing.

[0019] The demisting mechanism includes an exhaust pipe that is fixedly connected to the reaction chamber and connected to an external gas treatment system. Multiple wire mesh plates arranged in a circular pattern and staggered are fixedly connected inside the reaction chamber, and the positions of the wire mesh plates correspond to the positions of the exhaust pipe.

[0020] Compared with the prior art, the advantages of the present invention are as follows:

[0021] When the screw conveyor rotates, the rotating component moves in a circular motion, pushing the pressure column, driving the rotating ring to rotate and winding the steel guide rope. When the rotating component continues to rotate until it contacts the lifting plate on the outer wall of the sleeve, the wedge-shaped structure of the lifting plate forces the pressure plate away from the rotating ring and past the pressure column. After the pressure column loses its thrust, the movable cylinder swings back under its own gravity, and the steel guide rope loosens, causing the movable cylinder to continuously oscillate at a small angle at the end of the sleeve. The oscillation of the movable cylinder, on the one hand, scatters part of the chemical agent discharged from the sleeve circumferentially to the central edge area of ​​the reaction chamber, preventing the chemical agent from concentrating at the center point; on the other hand, the reciprocating motion of the movable cylinder itself agitates the reaction chamber. In addition, the reciprocating movement of the steel guide rope in the feed pipe also helps to agitate the chemical agent, promoting its smooth entry into the sleeve and avoiding blockage.

[0035] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0036] like Figures 1-12 The diagram shows an embodiment of a vehicle urea wastewater treatment device with an integrated swirl plate and wire mesh demisting structure provided by the present invention. It includes a multi-stage treatment system 1, which includes a filter device 101, a reaction chamber 102, a reverse osmosis device 103, and an discharge pool 104. The reaction chamber 102 is equipped with a dosing mechanism and a demisting mechanism. The demisting mechanism includes an exhaust pipe 23 that is fixedly connected to the reaction chamber 102. The exhaust pipe 23 is connected to an external gas treatment system. Multiple wire mesh plates 24 arranged in a circular pattern and staggered are fixedly connected inside the reaction chamber 102. The positions of the wire mesh plates 24 correspond to the positions of the exhaust pipe 23.

[0037] The dosing mechanism includes a feed pipe 22 and a sleeve 2 that penetrates into the reaction chamber 102. The sleeve 2 is equipped with a screw conveyor 3. It also includes a movable cylinder 4 located in the reaction chamber 102. The movable cylinder 4 has a relief groove 5 at its end. The movable cylinder 4 is rotatably connected to the sleeve 2 through the relief groove 5. A steel guide rope 6 that passes out of the reaction chamber 102 is pulled on the movable cylinder 4. The filtration device 101 consists of a sand filter and an activated carbon filter.

[0038] Explanation of wastewater treatment processes:

[0039] First, the wastewater is pressurized by a booster pump and then passed through a sand filter and an activated carbon filter in sequence to remove suspended solids, residual chlorine and organic matter;

[0040] Then, a chemical neutralization reaction is carried out in the reaction chamber 102 (with the addition of chemical agents by the dosing mechanism); when the mist-containing gas passes through the wire mesh plate 24, the mist droplets collide with the wire mesh plate 24 due to inertial collision and are captured. The small mist droplets converge and become larger, and finally fall down along the wire mesh plate 24 due to gravity, realizing gas-liquid separation. The gas enters the gas treatment system through the exhaust pipe 23.

[0041] Finally, the salt is desalinated by the reverse osmosis unit 103 and then enters the discharge pool 104.

[0042] The device also includes a movable cylinder 4 located inside the reaction chamber 102, which is rotatably connected to the end of the sleeve 2. Specifically, the end of the movable cylinder 4 is provided with a clearance groove 5, through which the movable cylinder 4 is rotatably connected to the sleeve 2. The clearance groove 5 ensures that the relative rotation between the movable cylinder 4 and the sleeve 2 is not interfered with, and also allows some chemical reagents to easily enter the interior of the movable cylinder 4 from the end of the sleeve 2. Preferably, a reinforcing plate 21 is fixedly connected to the movable cylinder 4, and the rotating connecting shaft of the sleeve 2 and the movable cylinder 4 is rotatably connected to the reinforcing plate 21 to enhance the structural strength and rotational stability of the connection.

[0043] The movable cylinder 4 and the sleeve 2 are located at the top of the reaction chamber 102 to avoid thermal damage to the movable cylinder 4 and the sleeve 2 caused by high temperature, and to ensure long-term reliable operation of the device in high temperature environment.

[0044] A steel guide rope 6 is pulled along the movable cylinder 4, extending out of the reaction chamber 102. One end of the steel guide rope 6 is fixedly connected to the movable cylinder 4, and the other end extends out of the movable cylinder 4, passing sequentially through the internal space of the reaction chamber 102, the inside of the feed pipe 22, and finally out of the reaction chamber 102. Inside the reaction chamber 102, the steel guide rope 6 is threaded through the movable shaft 20. Specifically, a fixed rod 19 is fixedly connected inside the reaction chamber 102, and the end of the fixed rod 19 is rotatably connected to the movable shaft 20, through which the steel guide rope 6 passes. The movable shaft 20 can adaptively rotate with the reciprocating motion of the steel guide rope 6 to reduce the frictional resistance during the movement of the steel guide rope 6.

[0045] A sealing block 12 is fixedly connected between the feed pipe 22 and the reaction chamber 102, and the steel guide rope 6 passes through the sealing block 12. The sealing block 12 ensures the sealing effect at the connection between the feed pipe 22 and the reaction chamber 102 when the steel guide rope 6 reciprocates, and also reduces the friction and wear of the steel guide rope 6 on the feed pipe 22 and the reaction chamber 102.

[0046] The device also includes a rotating ring 7 rotatably connected to the top of the sleeve 2. The rotating ring 7 is fitted onto the outer surface of the sleeve 2 and can rotate freely around the axis of the sleeve 2. After the steel guide rope 6 passes through the sealing block 12, it passes through the inside of the feed pipe 22 and is wound onto the rotating ring 7. Preferably, the rotating ring 7 has a winding groove 13 for winding the steel guide rope 6, and the steel guide rope 6 is embedded in the winding groove 13 to prevent it from coming out during winding. A pressure rod 14 that cooperates with the rotating ring 7 is fixedly connected to the outer surface of the sleeve 2. The pressure rod 14 fits against the edge of the rotating ring 7 to limit the movement trajectory of the steel guide rope 6 in the winding groove 13. More preferably, a pressure ball 15 located in the winding groove 13 is fixedly connected to the pressure rod 14. The pressure ball 15 presses against the steel guide rope 6, so that the steel guide rope 6 always remains in contact with the winding groove 13 during winding and release, achieving precise winding.

[0047] A pressure post 8 is fixedly connected to the edge of the rotating ring 7, and the pressure post 8 protrudes outward radially along the rotating ring 7. A rotating assembly with an elastic element 9 is fixedly connected to the screw conveyor mechanism 3, and a lifting plate 10 is fixedly connected to the outer surface of the sleeve 2. The rotating assembly rotates synchronously with the screw conveyor mechanism 3, and pushes the pressure post 8 through the pressure action, thereby driving the rotating ring 7 to rotate and winding the steel guide rope 6; when the rotating assembly continues to rotate until it contacts the lifting plate 10, it passes over the pressure post 8 under the action of the lifting plate 10, allowing the rotating ring 7 to rotate back.

[0048] The rotating assembly includes a fixed plate 16 and a pressure plate 17. The fixed plate 16 is fixedly connected to the central shaft of the screw conveyor mechanism 3 and rotates synchronously with the central shaft. A rod 18, which inserts into the fixed plate 16, is fixedly connected to the pressure plate 17. The pressure plate 17 can move relative to the fixed plate 16 along the axis of the rod 18. The elastic element 9 is a compression spring, fitted onto the outside of the rod 18. Both ends of the elastic element 9 are connected to the fixed plate 16 and the pressure plate 17, respectively. Under the elastic force of the elastic element 9, the pressure plate 17 always tends to move closer to the rotating ring 7.

[0049] The lifting plate 10 is fixedly connected to the outer surface of the sleeve 2, and the end of the lifting plate 10 has a wedge-shaped structure. When the pressure plate 17 rotates with the screw conveyor mechanism 3 to the position of the lifting plate 10, the pressure plate 17 first contacts the wedge-shaped inclined surface of the lifting plate 10. Under the guidance of the wedge-shaped inclined surface, the pressure plate 17 overcomes the elastic force of the elastic element 9 and moves away from the rotating ring 7 along the insert rod 18, so that the pressure plate 17 passes over the pressure column 8, and the pressure column 8 is no longer subjected to the thrust of the pressure plate 17.

[0050] A motor 11 is fixedly connected to the outer surface of the reaction chamber 102, and the output shaft of the motor 11 is fixedly connected to the central shaft of the screw conveyor mechanism 3. The motor 11 provides rotational power to the screw conveyor mechanism 3, which performs a continuous and slow rotational motion within the sleeve 2.

[0051] Working principle: During feeding: Chemical reagents are placed into the feed pipe 22 and enter the sleeve 2. At this time, the motor 11 drives the screw conveyor 3 to slowly rotate in its original position inside the sleeve 2, so that the chemical reagents enter the reaction chamber 102 slowly along the sleeve 2 under the action of the screw conveyor 3.

[0052] When the chemical reagent comes out of the sleeve 2, part of it directly enters the middle of the reaction chamber 102, and the other part enters the movable cylinder 4 (the setting of the clearance groove 5 ensures the rotation between the movable cylinder 4 and the sleeve 2, and also facilitates the entry of some chemical reagent into the movable cylinder 4). As the movable cylinder 4 slowly moves back and forth at a certain angle, it drives the chemical reagent in the movable cylinder 4 to disperse to the middle edge (not the inner wall of the reaction chamber 102), and the reciprocating movable cylinder 4 stirs the wastewater to ensure the reaction between the chemical reagent and the wastewater.

[0053] The implementation process for the slow reciprocating motion of the movable cylinder 4 is as follows:

[0054] While the screw conveyor 3 rotates slowly, it drives the fixed plate 16 and the pressure plate 17 to make circular motion. Under the action of the elastic element 9, the pressure plate 17 presses against the rotating ring 7 and makes circular motion. The pressure plate 17 contacts the pressure column 8 on the rotating ring 7 and pushes the pressure column 8 to make circular motion, thereby making the rotating ring 7 rotate. The receiving groove of the rotating ring 7 winds up the steel guide rope 6. The pressure rod 14 is attached to the edge of the rotating ring 7, and part of the pressure ball 15 is located in the receiving groove. The cooperation of the pressure rod 14 and the pressure ball 15 makes the steel guide rope 6 accurately receive into the receiving groove.

[0055] After the pressure plate 17, which continues to move in a circular motion, contacts the lifting plate 10, the wedge-shaped structure of the lifting plate 10 causes the pressure plate 17 to move away from the rotating ring 7, so that the pressure plate 17 passes over the pressure column 8. At this time, the pressure column 8 is not pushed by the pressure plate 17. Under the gravity of the movable cylinder 4, the pressure column 8 and the rotating ring 7 rotate, and the steel guide rope 6 slackens.

[0056] This causes the steel guide rope 6 to reciprocate, and in conjunction with the adaptive rotation of the movable shaft 20, causes the movable cylinder 4 to reciprocate at a certain angle.

[0057] It is worth noting that a sealing block 12 is provided in this application to ensure the sealing effect when the steel guide rope 6 moves, and also to reduce the friction of the steel guide rope 6 on the feed pipe 22 and the reaction chamber 102.

[0058] The steel guide rope 6 reciprocates within the feed pipe 22, which helps the chemical agent enter the sleeve 2 from the feed pipe 22.
