Abstract
Description
Technical Field
[0001] This utility model relates to the field of flue gas purification technology, specifically a flue gas desulfurization control device based on continuous emission monitoring. Background Technology
[0002] Flue gas desulfurization (FGD) refers to the process of removing sulfur oxides (such as SO2 and SO3) from flue gas or other industrial waste gases to meet environmental requirements. The main purpose of FGD is to reduce sulfur oxide emissions generated during coal or oil combustion, thereby protecting the environment and human health.
[0003] Flue gas is desulfurized using SDS desulfurization technology. SDS desulfurization technology uses dry desulfurizing agent as the desulfurizing agent. The ground desulfurizing agent is transported to the desulfurization tower and fully mixed with the flue gas to react. However, existing desulfurization control devices generally use a fixed frequency to feed the desulfurizing agent when it is being transported and mixed with the flue gas. This makes it impossible to adjust the amount of desulfurizing agent fed according to the changes in the sulfur dioxide concentration in the flue gas, which leads to waste of desulfurizing agent or excessive emissions. To address the above problems, the inventors propose a flue gas desulfurization control device based on continuous emission monitoring to solve the above problems. Utility Model Content
[0004] To address the issue that desulfurization control devices typically use a fixed frequency for feeding desulfurizing agent when mixing it with flue gas, making it impossible to adjust the amount of desulfurizing agent fed, the purpose of this invention is to provide a flue gas desulfurization control device based on continuous emission monitoring.
[0005] To solve the above technical problems, this utility model adopts the following technical solution: A flue gas desulfurization control device based on continuous emission monitoring, including a control box, a rotating rod rotatably disposed inside the control box, a fixed seat fixedly sleeved on the outer surface of the rotating rod, an adjusting plate fixedly disposed on one side of the fixed seat, a worm gear fixedly disposed on one side of the rotating rod, an mounting plate fixedly disposed on one side of the control box, a first motor mounted on one side of the mounting plate, a rotating shaft fixedly disposed at the output end of the first motor, a first bevel gear fixedly sleeved on the outer surface of the rotating shaft, a fixed rod rotatably disposed inside the mounting plate, a second bevel gear fixedly disposed on the top surface of the fixed rod, the first bevel gear meshing with the second bevel gear, a worm gear fixedly sleeved on the outer surface of the fixed rod, the worm gear meshing with the worm gear, a fixed frame fixedly disposed inside the control box, the rotating rod rotatably disposed within the fixed frame, and the desulfurizing agent is first poured into the screen frame. Then, the cylinder is activated, causing the screen frame to slide the slider in the chute and move the guide rod. This causes the toothed ring on the guide rod surface to mesh with the toothed plate, allowing the guide rod to rotate. This allows the dispersing rod to break up the clumps of desulfurizing agent, which then falls from the screen frame into the control box. Next, the first motor is activated, causing the rotating shaft to drive the first bevel gear to rotate. The first bevel gear meshes with the second bevel gear, which in turn drives the fixed rod to rotate. The fixed rod drives the worm gear to rotate, which meshes with the worm wheel, causing the rotating rod to rotate. This rotates the fixed seat and the adjusting plate downwards, allowing the opening and closing of the adjusting plate to be adjusted. This allows for the regulation of the amount of desulfurizing agent fed during delivery, and the agent is delivered from the control box into the delivery pipe. Then, the second motor is activated, causing the spiral conveying roller to rotate in the delivery pipe, allowing the desulfurizing agent to fall from the discharge frame, thus enabling the delivery of the desulfurizing agent.

This allows for the adjustment of the amount of desulfurizer fed during the conveying of the desulfurizer, preventing waste of the desulfurizer or excessive emissions.
[0010] 2. The guide rod drives the dispersing rod to rotate, which can break up the clumps of desulfurizing agent and then let it fall from the screen frame, avoiding the clumps of desulfurizing agent falling and clogging the conveying pipe, thus improving the desulfurization efficiency.

[0021] 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.
[0022] Example: Figure 1-8As shown, this utility model provides a flue gas desulfurization control device based on continuous emission monitoring, including a control box 1. A rotating rod 14 is rotatably mounted inside the control box 1. A fixed seat 12 is fixedly fitted onto the outer surface of the rotating rod 14. An adjusting plate 13 is fixedly mounted on one side of the fixed seat 12. A worm gear 15 is fixedly mounted on one side of the rotating rod 14. A mounting plate 2 is fixedly mounted on one side of the control box 1. A first motor 21 is mounted on one side of the mounting plate 2. A rotating shaft 22 is fixedly mounted on the output end of the first motor 21. A fixed sleeve is fitted onto the outer surface of the rotating shaft 22. A first bevel gear 23 is provided. A fixed rod 24 is rotatably mounted inside the mounting plate 2. A second bevel gear 25 is fixedly mounted on the top surface of the fixed rod 24. The first bevel gear 23 and the second bevel gear 25 mesh with each other. A worm gear 26 is fixedly sleeved on the outer surface of the fixed rod 24. A worm wheel 15 meshes with the worm gear 26. A fixed frame 11 is fixedly mounted inside the control box 1. A rotating rod 14 is rotatably mounted inside the fixed frame 11. The concentration of particulate matter in the flue gas is measured by a flue gas emission parameter monitoring system, and the concentration of gaseous pollutants in the flue gas is measured by a gaseous pollutant monitoring system. The flue gas emission monitoring system monitors parameters such as temperature, pressure, and flow rate, including sulfur dioxide and nitrogen oxides. It then transmits the real-time data from the flue gas emission parameter monitoring system, gaseous pollutant monitoring system, and flue gas monitoring system to a data acquisition system. This data acquisition system collects and analyzes the data to determine the concentration of sulfur dioxide in the flue gas. The analyzed data is then sent to the main control system, which controls the start, stop, forward, and reverse rotation of the first motor 21. Starting the first motor 21 causes the rotating shaft 22 to drive the first bevel gear 23 to rotate. The first bevel gear 23 meshes with the second bevel gear 25, which in turn drives the fixed rod 24 to rotate. The fixed rod 24 then drives the worm gear 26 to rotate, which meshes with the worm wheel 15. This causes the rotating rod 14 to rotate, which in turn drives the fixed seat 12 and the adjusting plate 13 to rotate downwards. This allows for adjustment of the opening and closing of the adjusting plate 13, regulating the amount of desulfurizer fed during desulfurization to prevent waste or excessive emissions.
[0023] A support frame 3 is fixedly installed on the top surface of the control box 1. A screen frame 31 is slidably installed inside the support frame 3. A guide rod 35 is rotatably installed inside the screen frame 31. A dispersing rod 37 is fixedly sleeved on the outer surface of the guide rod 35. A toothed plate 34 is fixedly installed inside the support frame 3. A toothed ring 36 is fixedly sleeved on the outer surface of the guide rod 35. The toothed plate 34 and the toothed ring 36 mesh with each other. A cylinder 32 is installed on one side of the support frame 3. The output end of the cylinder 32 is fixedly installed on one side of the screen frame 31. A sliding groove 301 is opened inside the support frame 3. Sliding blocks 33 are fixedly installed on both sides of the screen frame 31. The sliding blocks 33 are slidably installed in the sliding groove 301.
[0024] By adopting the above technical solution, a screen is provided at the bottom of the screen frame 31. After the desulfurizing agent is poured into the screen frame 31, the cylinder 32 is turned on, so that the screen frame 31 drives the slider 33 to slide in the slide groove 301 and drives the guide rod 35 to move. This causes the toothed ring 36 on the surface of the guide rod 35 to mesh with the toothed plate 34, thereby enabling the guide rod 35 to rotate. This allows the dispersing rod 37 to disperse the clumps of desulfurizing agent, which then falls out of the screen frame 31. This prevents the clumps of desulfurizing agent from falling and blocking the conveying pipe 41, thus improving the desulfurization efficiency.
[0025] A base 4 is provided below the control box 1. A conveying pipe 41 is fixedly provided on the top surface of the base 4. A second motor 42 is installed on one side of the conveying pipe 41. A spiral conveying roller 43 is fixedly provided at the output end of the second motor 42. The spiral conveying roller 43 is rotatably located inside the conveying pipe 41. The control box 1 is fixedly connected to the conveying pipe 41. A feeding frame 44 is fixedly provided on the outer surface of the conveying pipe 41.
[0026] By adopting the above technical solution, by turning on the second motor 42, the spiral conveying roller 43 rotates inside the conveying pipe 41, thereby causing the desulfurizing agent to fall from the feeding frame 44, thus enabling the desulfurizing agent to be conveyed.
[0027] Working principle: First, the desulfurizing agent is poured into the screen frame 31. Then, the cylinder 32 is turned on, causing the screen frame 31 to move the slider 33 within the chute 301, which in turn moves the guide rod 35. This causes the toothed ring 36 on the surface of the guide rod 35 to mesh with the toothed plate 34, thus allowing the guide rod 35 to rotate. This causes the dispersing rod 37 to break up the clumps of desulfurizing agent, which then falls from the screen frame 31 into the control box 1. Next, the first motor 21 is turned on, causing the rotating shaft 22 to drive the first bevel gear 23 to rotate. The first bevel gear 23 meshes with the second bevel gear 25, causing the second bevel gear... 25 drives the fixed rod 24 to rotate, the fixed rod 24 drives the worm 26 to rotate, the worm 26 meshes with the worm wheel 15 to drive the rotation rod 14 to rotate, and drives the fixed seat 12 and the adjusting plate 13 to rotate downward, thereby adjusting the opening and closing size of the adjusting plate 13, so as to adjust the amount of desulfurizer fed when conveying the desulfurizer, and convey it from the control box 1 to the conveying pipe 41. Then, the second motor 42 is turned on, so that the spiral conveying roller 43 rotates in the conveying pipe 41, thereby causing the desulfurizer to fall from the feeding frame 44, thus enabling the conveying of the desulfurizer.
