Technical Field
[0001] This utility model relates to the field of environmental protection technology, and in particular to a processing device for reducing nitrogen oxide solid particulate matter. Background Technology
[0002] The nitrogen oxide solid particulate matter reducing agent treatment and processing device is a specialized piece of equipment focused on air pollution control and serving industrial flue gas purification. Its core function is to pre-treat reducing agents in specific solid particulate forms and accurately deliver the processed qualified solid particulate matter reducing agents to the flue gas systems of emission sources such as industrial boilers, kilns, and coal-fired power plant units. This converts harmful nitrogen oxides into harmless nitrogen and water, thereby significantly reducing the amount of nitrogen oxides emitted in industrial flue gas and mitigating the harm of nitrogen oxides to the atmospheric environment and human health. It is one of the key technological equipment for industrial enterprises to achieve nitrogen oxide emission reduction and comply with environmental regulations.
[0003] The nitrogen oxide solid particulate matter reducing agent treatment and processing device mainly consists of a feeding system, a pyrolysis tank, reducing agent pretreatment auxiliary components, a conveying and regulating system, and a control and monitoring system. The feeding system includes a hopper, which is responsible for stably conveying the solid particulate reducing agent to the pyrolysis tank. The control and monitoring system uses controllers to regulate the feeding speed and the operating conditions of the pyrolysis tank in real time. Its working principle is that the device sends the solid particulate reducing agent into the pyrolysis tank through the feeding system. After heating and pretreatment in the pyrolysis tank, the harmful substances are converted into harmless substances.
[0004] In the existing technology, some nitrogen oxide solid particulate matter reducing agent processing devices still use traditional manual feeding, which makes it difficult to ensure the continuity and stability of the reducing agent supply. This results in uneven feeding intervals and deviations in the amount of reducing agent fed at one time, leading to insufficient or excessive reducing agent in the pyrolysis tank. Therefore, a nitrogen oxide solid particulate matter reducing agent processing device is proposed to solve the above problems. Summary of the Invention
[0005] To overcome the above deficiencies, this utility model provides a nitrogen oxide solid particulate matter reducing agent treatment and processing device, which aims to improve the problem of material feeding deviation in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A nitrogen oxide solid particulate matter reducing agent treatment and processing device includes a base, a pyrolysis tank fixedly connected to the top of the base, a funnel fixedly connected to the top of the pyrolysis tank, a feeding mechanism installed on the top of the base, a water tank fixedly connected to the top of the base, a water pump fixedly connected to the top of the water tank, and a heat dissipation mechanism installed at the output end of the water pump. The feeding mechanism includes two support plates, the bottom of which is fixedly connected to the top of the base. A motor is fixedly connected to the outside of one of the support plates. A rotating shaft is fixedly connected to the drive end of the motor. Two sprockets are fixedly connected to the outside of the rotating shaft. A chain is sleeved on the outside of each of the two sprockets. A connecting plate is fixedly connected to the outside of the chain. A connecting rod is fixedly connected inside the connecting plate. A material box is rotatably connected to the outside of the connecting rod. A flipping component is installed on the outside of the material box. As a further description of the above technical solution: The flipping assembly includes a stop block, the outside of which is fixedly connected to the outside of the material box, the inside of which is fixedly connected to a discharge pipe, and the inside of which is fixedly connected to a fixing plate. As a further description of the above technical solution: The heat dissipation mechanism includes a pipe, which is fixedly connected to the output end of the water pump. Multiple heat dissipation fins are fixedly connected to the outside of the pipe. A filter plate is slidably connected inside the pipe. Two rotating columns are rotatably connected inside the filter plate. A rotating plate is fixedly connected to the far side of the two rotating columns. Multiple baffles are slidably connected inside the pipe. A spring is fixedly connected to the far side of the two baffles. A connecting rod is fixedly connected to the near side of the two baffles. A limit plate is fixedly connected to the near side of the two connecting rods. As a further description of the above technical solution: A control console is fixedly connected to the top of the base, and a motor is fixedly connected to the top of the pyrolysis tank. As a further description of the above technical solution: The driving end of the second motor is fixedly connected to a stirring rod, and the outside of the stirring rod is rotatably connected to the inside of the pyrolysis tank. As a further description of the above technical solution: The external shaft is rotatably connected to the inside of the support plate, and the top end of the stop block is in contact with the bottom end of the fixed plate; As a further description of the above technical solution: The outside of the rotating column is rotatably connected to the inside of the pipe, and the outside of the limiting plate is engaged with the inside of the rotating column; As a further description of the above technical solution: The limiting plate is externally slidably connected to the inside of the pipe, and the connecting rod is externally slidably connected to the inside of the pipe.
[0007] This utility model has the following beneficial effects: 1. In this utility model, the motor drives the rotating shaft to rotate, and the two sprockets rotate synchronously with the rotating shaft, so that the chain performs cyclic transmission, thereby the connecting plate moves synchronously. The connecting plate drives the material box to move through the connecting rod. When the baffle outside the material box contacts the fixed plate, the material box flips around the connecting rod, and the material enters the funnel through the discharge pipe. This effectively reduces manual input, avoids excessive labor intensity and safety accidents caused by frequent manual handling of heavy objects, ensures the stability of the feeding amount, and lays the foundation for the uniformity of subsequent pyrolysis processing, thereby achieving the effect of automatic feeding.
[0008] 2. In this utility model, by rotating the rotating plate, the rotating column is driven to rotate, thereby squeezing the limiting plate. The limiting plate then squeezes the baffle through the connecting rod, thereby compressing the spring. The limiting plate will enter the pipeline, thereby allowing the filter plate to be removed. This prevents the filter plate from being affected by heat dissipation and allows for quick removal of the filter plate, reducing replacement time, maintenance difficulty and time costs. This ensures that the temperature inside the tank is controlled and stabilized within the optimal pyrolysis range, thereby achieving the effect of heat dissipation. Attached Figure Description

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0012] A nitrogen oxide solid particulate matter reducing agent treatment and processing apparatus, referring to Figures 1 to 3 The device includes a base 1, which serves as the basic support structure for the entire device. A pyrolysis tank 2 is fixedly connected to the top of the base 1. This tank is the core reaction vessel for the treatment and processing of nitrogen oxide solid particulate matter reducing agent. A funnel 3 is fixedly connected to the top of the pyrolysis tank 2 to accurately introduce materials into the pyrolysis tank 2. A feeding mechanism 4 is installed on the top of the base 1. A water tank 5 is fixedly connected to the top of the base 1 to store cooling water. A water pump 6 is fixedly connected to the top of the water tank 5 to pressurize and extract the cooling water in the water tank 5. A heat dissipation mechanism 7 is installed at the output end of the water pump 6. The feeding mechanism 4 includes two support plates 41. The bottom of both support plates 41 is fixedly connected to the top of the base 1, which serves to support and fix other components of the feeding mechanism 4. One of the support plates 41 is fixedly connected to a motor 42, which is the power source of the feeding mechanism 4. The drive end of the motor 42 is fixedly connected to a rotating shaft 43, which drives the motor 42 to rotate. Two sprockets 44 are fixedly connected to the outside of the rotating shaft 43, which rotate synchronously under the drive of the rotating shaft 43. Chains 45 are sleeved on the outside of the two sprockets 44, which perform cyclic transmission under the drive of the sprockets 44. A connecting plate 46 is fixedly connected to the outside of the chain 45. When the chain 45 is driven, the connecting plate 46 moves with the chain 45. A connecting rod 47 is fixedly connected inside the connecting plate 46, which provides a fulcrum for rotation. A material box 48 is rotatably connected to the outside of the connecting rod 47, which is the core component of the feeding mechanism 4 that carries materials. A flipping component 49 is installed on the outside of the material box 48.
[0013] The flipping assembly 49 includes a stop 491, which is externally fixedly connected to the outside of the material box 48. The material box 48 is flipped by touching the stop. The material box 48 is internally fixedly connected to a discharge pipe 492, and the material is poured from the discharge pipe 492 into the funnel 3. The funnel 3 is internally fixedly connected to a fixing plate 493, which generates a blocking force on the stop 491, forcing the material box 48 to flip around the connecting rod 47.
[0014] Specifically, motor 42 drives shaft 43 to rotate, causing two sprockets 44 to rotate together, which in turn causes chain 45 to circulate and drive connecting plate 46 to move together. This, in turn, drives material box 48 to move through connecting rod 47. When it rises to a certain position, stop block 491 touches fixed plate 493, and chain 45 continues to drive material box 48 to rise, causing material box 48 to flip outside connecting rod 47, so that material is poured from discharge pipe 492 into funnel 3.
[0015] Reference Figure 1 , Figure 4 and Figure 5 The heat dissipation mechanism 7 includes a pipe 71, which is externally fixedly connected to the output end of the water pump 6. One end of the pipe 71 is connected to the output end of the water pump 6, and the other end flows back to the water tank 5, providing a flow channel for cooling water. Multiple heat dissipation fins 72 are fixedly connected to the outside of the pipe 71 to increase the contact area between the pipe 71 and the air. A filter plate 73 is slidably connected inside the pipe 71 to filter impurities in the cooling water and prevent impurities from clogging the pipe 71. Two rotating columns 74 are rotatably connected inside the filter plate 73 to fix the position of the filter plate 73 inside the pipe 71.
[0016] Rotating plates 75 are fixedly connected to the far sides of the two rotating columns 74 to provide operating fulcrums for the workers. Multiple baffles 76 are slidably connected inside the pipe 71 for transmission. Springs 77 are fixedly connected to the far sides of the two baffles 76 to provide restoring elasticity for the baffles 76. Connecting rods 78 are fixedly connected to the near sides of the two baffles 76. When the baffles 76 slide under the action of the springs 77, the connecting rods 78 move synchronously. Limiting plates 79 are fixedly connected to the near sides of the two connecting rods 78 to fix the position of the filter plate 73 by engaging with the rotating columns 74.
[0017] Specifically, water pump 6 draws water from water tank 5 through pipe 71 and heat dissipation fins 72 to heat and control the temperature of pyrolysis tank 2. When the water flows back to water tank 5, it is filtered through filter plate 73. Rotating plate 75 drives rotating column 74 to rotate and squeeze limit plate 79, thereby squeezing connecting rod 78 and baffle 76, thus compressing spring 77. As a result, limit plate 79 slides into pipe 71 to release the fixation of rotating column 74. After removing it, the fixation of filter plate 73 is released.
[0018] Reference Figure 1 , Figure 2 and Figure 4The top of the base 1 is fixedly connected to the control console 8, which centrally controls the operation of each component of the control device. The top of the pyrolysis tank 2 is fixedly connected to the motor 9, which is the power source for driving the stirring. The drive end of the motor 9 is fixedly connected to the stirring rod 10, which rotates under the drive of the motor 9. The outside of the stirring rod 10 is rotatably connected to the inside of the pyrolysis tank 2. The stirring blades can turn the material in the pyrolysis tank 2 and break the material agglomeration. The outside of the rotating shaft 43 is rotatably connected to the inside of the support plate 41. When the motor 42 drives the rotation, it can synchronously drive the two sprockets 44 to rotate.
[0019] The top of the stop block 491 contacts the bottom of the fixing plate 493. The fixing plate 493 generates a blocking force on the stop block 491, forcing the material box 48 to rotate around the connecting rod 47. The outside of the rotating column 74 is rotatably connected to the inside of the pipe 71. When the rotating column 74 is rotated, it is released from fixation and can be removed. The outside of the limiting plate 79 is engaged with the inside of the rotating column 74. The engagement of the limiting plate 79 and the rotating column 74 fixes the position of the filter plate 73. The outside of the limiting plate 79 is slidably connected to the inside of the pipe 71. When the limiting plate 79 is squeezed, it slides into the pipe 71. The outside of the connecting rod 78 is slidably connected to the inside of the pipe 71, which plays a role in force transmission.
[0020] Specifically, the control console 8 can control the start of each device. Motor 2 9 drives the stirring rod 10 to rotate, thereby stirring the material. When motor 1 42 starts, it can drive the rotating shaft 43 to rotate, thereby causing the two sprockets 44 to rotate synchronously. When the stop block 491 touches the fixed plate 493, the material box 48 is still rising, thereby causing the material box 48 to flip around the connecting rod 47 and pour the material out from the discharge pipe 492. When the limiting plate 79 is aligned with the groove of the rotating column 74, the spring 77 rebounds and causes the limiting plate 79 to be stuck in the rotating column 74. By rotating the rotating plate 75, the rotating column 74 is driven to rotate, thereby squeezing the limiting plate 79 and causing it to slide into the pipe 71. The movement of the limiting plate 79 will drive the connecting rod 78 to move together.
[0021] The implementation principle of this application embodiment is as follows: When automatic material conveying is required, motor 42 is started, which drives the rotating shaft 43 to rotate, thereby driving the two sprockets 44 to rotate synchronously, which in turn drives the externally sleeved chain 45 to perform cyclic transmission. The chain 45 drives the connecting plate 46 to move together, and the connecting plate 46 drives the material box 48 to move through the connecting rod 47. When the material box 48 moves, when the stop block 491 outside the material box 48 contacts the bottom end of the fixed plate 493, the fixed plate 493 forms a blocking force on the stop block 491, while the material box 48 continues to move with the chain 45, thereby causing the material box 48 to flip around the connecting rod 47, so that the material enters the funnel 3 through the discharge pipe 492. This avoids excessive labor intensity and safety accidents caused by frequent manual handling of heavy objects, ensures the stability of the feeding amount, and lays the foundation for the uniformity of subsequent pyrolysis processing, thereby achieving the effect of automatic feeding.
[0022] To prevent the temperature of the pyrolysis tank 2 from overheating during operation, the water pump 6 is activated. The water pump 6 draws cooling water from the water tank 5, pressurizes it, and delivers it to the pipe 71. The heat dissipation fins 72 on the outside of the pipe 71 increase the contact area between the pipe 71 and the air. The water flows back to the water tank 5 after being filtered by the filter plate 73 inside the pipe 71, thus dissipating heat. When the filter plate 73 needs to be replaced or cleaned, the rotating plate 75 is rotated, which drives the rotating column 74 to rotate, thereby squeezing the limiting plate 79. This causes the limiting plate 79 to squeeze the baffle 76 via the connecting rod 78, thus causing the baffle 76 to... 6. When the spring 77 is compressed, the limiting plate 79 will enter the pipe 71, thereby releasing the fixation of the rotating column 74. The column 74 can then be removed to disassemble the filter plate 73. During installation, the limiting plate 79 only needs to be aligned with the groove of the rotating column 74. The spring 77 will then reset and press, causing the limiting plate 79 to be locked into the rotating column 74 for fixation, thus preventing any impact on heat dissipation. This allows for quick disassembly of the filter plate 73, reducing replacement time, maintenance difficulty, and time costs. It also ensures that the temperature is controllable and stabilizes the temperature inside the tank within the optimal pyrolysis range, thereby achieving the effect of heat dissipation.
[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
