Description

Technical Field

[0001] This utility model relates to the field of flue gas deacidification technology, and in particular to a flue gas deacidification tower. Background Technology

[0002] Flue gas is a mixture of gases containing various components produced during industrial production or fuel combustion. It includes not only conventional components such as carbon dioxide and water vapor, but also acidic gases such as sulfur dioxide, hydrogen chloride, and hydrogen fluoride, as well as pollutants such as particulate matter and nitrogen oxides. When these acidic gases are released into the atmosphere, they form acid rain, corroding buildings, damaging vegetation, polluting water bodies, and harming the ecological environment and human health. Simultaneously, they cause severe corrosion to downstream equipment such as chimneys and fans, shortening their service life. Flue gas desulfurization towers, through chemical reactions such as neutralization with desulfurizing agents, can effectively remove acidic components from flue gas, reducing the emission of acidic pollutants. They are key environmental protection equipment for ensuring environmental quality, reducing equipment corrosion, and achieving compliant industrial flue gas emissions.

[0003] Most desulfurization towers introduce flue gas through a flue and inlet pipe, with the gas rising from the bottom. Inside, atomized desulfurizing agent is sprayed, ensuring full contact with the rising flue gas. The acidic gas and desulfurizing agent undergo a neutralization reaction. Finally, a demister removes the mist droplets carried in the flue gas, and the purified gas is discharged through the outlet. However, the connection between the flue and inlet pipe is typically achieved by bolting two flanges tightly together and using gaskets to prevent leakage. Vibration during operation can cause alternating stress on the bolts, leading to gradual loosening and leakage. This not only reduces the desulfurization tower's efficiency but also pollutes the surrounding environment and harms the health of workers.

[0004] Therefore, it is necessary to provide a new flue gas desulfurization tower to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a flue gas desulfurization tower.

[0006] This utility model provides a flue gas desulfurization tower comprising: a carrying plate, a flue, an output component, an inclined plate, and a connecting component. A desulfurization tank is fixedly connected to the top of the carrying plate, and multiple support legs are fixedly connected to the bottom of the carrying plate. A water tank is fixedly connected to the carrying plate mounted on the adjacent side of the multiple support legs. An output component is installed at the output end of the water tank.

An arc-shaped top is fixedly connected to the top of the desulfurization tank. An air outlet pipe is fixedly connected to the top of the arc-shaped top. A demister is installed at the bottom of the arc-shaped top. An air inlet pipe is fixedly connected to one side of the desulfurization tank. A first connecting plate is fixedly connected to the side of the air inlet pipe away from the desulfurization tank. A second connecting plate is fixedly connected to one side of the flue. The first connecting plate is connected to the second connecting plate through the connecting component. A sealing ring is provided at the connection between the air inlet pipe and the flue.

[0007] Preferably, the output component includes a water pump, the input end of which is fixedly connected to the output end of the water tank, a transmission pipe is fixedly connected to the output end of the water pump, a delivery pipe is fixedly connected to one end of the transmission pipe, and multiple spray heads are fixedly connected to the bottom end of the delivery pipe.

[0008] Preferably, the connecting assembly includes multiple bolts, the outer side of the bolts is slidably connected to the interior of the first connecting plate, the outer side of the bolts is slidably connected to the interior of the second connecting plate, two nuts are threadedly connected to the outer side of the bolts away from the first connecting plate, a washer is provided on the adjacent side of the two nuts, and a spring is sleeved on the outer side of the bolts.

[0014] Compared with related technologies, the flue gas desulfurization tower provided by this utility model has the following beneficial effects:

[0015] This invention utilizes the synergistic action of bolts, nuts, washers, and springs in the connecting assembly to ensure a tight fit between the intake pipe and the flue's connecting plate during installation, generating effective pre-tightening force. During operation, facing alternating stresses generated by equipment vibration, the springs elastically deform to absorb and buffer energy, using a counterforce to prevent bolt displacement, reducing the possibility of loosening and ensuring connection stability. Combined with the sealing ring at the connection point, the springs deform under the bolt pre-tightening force to fill gaps, enhancing the sealing effect and preventing flue gas leakage. This avoids problems such as reduced processing efficiency, environmental pollution, and harm to human health caused by leakage.

[0016] This invention uses an inclined plate inside the deacidification tank to make the flue gas flow path tortuous, increasing the contact time and area with the atomized deacidifying agent. The filling layer further increases the contact area and enhances mass transfer, allowing the acidic gas to fully react with the deacidifying agent. Compared with some simple deacidification towers, it significantly improves the deacidification efficiency and more effectively removes acidic components from the flue gas.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1 to 4A flue gas deacidification tower includes: a carrying plate 1, a deacidification tank 2 fixedly connected to the top of the carrying plate 1, and multiple support legs 3 vertically fixedly connected to the bottom of the carrying plate 1. The multiple support legs 3 are evenly distributed, and a water tank 4 is fixedly connected to the carrying plate installed on the side close to the multiple support legs 3. The bottom of the deacidification tank 2 and the top of the water tank 4 are fixedly connected, and the connection is well sealed to prevent solution leakage.

[0025] The output component is installed at the output end of the water tank 4. The output component includes a water pump 5, which is a device with specific power and head. The input end of the water pump 5 is fixedly connected to the output end of the water tank 4 through a sealed pipe to ensure that there is no leakage during the solution transmission process. The output end of the water pump 5 is fixedly connected to a transmission pipe 6. One end of the transmission pipe 6 is tightly connected to the water pump 5, and the other end is fixedly connected to a delivery pipe 7. The outside of the delivery pipe 7 is fixedly connected to the inside of the top of the deacidification tank 2. The bottom end of the delivery pipe 7 is fixedly connected to multiple spray heads 8, which can uniformly atomize and spray the deacidification agent solution.

[0026] Inclined plates 9 are symmetrically fixedly connected inside the deacidification tank 2. The inclination angle of the inclined plates 9 is precisely calculated and designed, and their smooth surfaces effectively guide the flue gas to flow along a predetermined tortuous path inside the deacidification tank 2. A filling layer 10 is fixedly connected to the middle of the inside of the deacidification tank 2, located between the two inclined plates 9. The filling layer 10 is composed of specific fillers with a large specific surface area and good chemical stability. An activated carbon plate 11 is fixedly connected at the connection between the deacidification tank 2 and the water tank 4. The activated carbon plate 11 is made of high-quality activated carbon material with a rich pore structure, which can effectively adsorb impurities in the solution. An arc-shaped top 1 is fixedly connected to the top of the deacidification tank 2. 2. The design of the arc-shaped top 12 conforms to the principles of aerodynamics, which can guide the flue gas to flow smoothly upward. The top of the arc-shaped top 12 is fixedly connected to the exhaust pipe 13 for discharging the purified flue gas. The bottom of the arc-shaped top 12 is equipped with a demister. The demister adopts a high-efficiency demister structure, which can effectively remove the mist droplets carried in the flue gas. The side of the deacidification tank 2 is fixedly connected to the air inlet pipe 14. The side of the air inlet pipe 14 away from the deacidification tank 2 is fixedly connected to the first connecting plate 15. The side of the flue 17 is fixedly connected to the second connecting plate 16. The materials of the first connecting plate 15 and the second connecting plate 16 are matched with those of the air inlet pipe 14 and the flue 17, and have sufficient strength and flatness to ensure the tightness of the connection.

[0027] The connecting assembly includes a first connecting plate 15 connected to a second connecting plate 16. A sealing ring is provided at the connection between the air intake pipe 14 and the flue 17, providing good elasticity and sealing performance. The air intake pipe 14 is connected to the flue 17 via the connection between the first connecting plate 15 and the second connecting plate 16. The connecting assembly includes multiple bolts 18. The outer side of the bolts 18 is slidably connected to the inner side of the first connecting plate 15, allowing them to pass smoothly through the holes in the connecting plate. The outer side of the bolts 18 is also slidably connected to the inner side of the second connecting plate 16. Two nuts 19 are threadedly connected to the outer side of the bolts 18 away from the first connecting plate 15. One side of one nut 19 contacts one side of the second connecting plate 16. The two nuts 19 are of the same specification as the bolts 18, providing good tightening performance. Washers 20 are provided on the adjacent sides of the two nuts 19. A spring 21 is sleeved on the outer side of the bolts 18. The spring 21 has a suitable elastic coefficient and fatigue life. The two ends of the spring 21 are fixedly connected to the adjacent sides of the two washers 20, ensuring stable operation under stress.

[0028] The working principle of the flue gas desulfurization tower provided by this utility model is as follows:

[0029] First, connect the intake pipe 14 and the flue 17. Align the first connecting plate 15 with the second connecting plate 16. Then, pass the bolt 18 through the corresponding holes in the first connecting plate 15 and the second connecting plate 16 in sequence. Next, screw on a nut 19 and tighten it initially. Then, put on a washer 20, followed by a spring 21 and another washer 20. Finally, tighten the second nut 19. By tightening the nut 19, the bolt 18 generates a preload, causing the first connecting plate 15 and the second connecting plate 16 to fit tightly together. At the same time, the spring 21 is compressed. At this time, the spring 21 stores elastic potential energy. The sealing ring at the connection between the intake pipe 14 and the flue 17 is squeezed and deformed under the preload of the bolt 18, filling the tiny gaps between the connecting surfaces. To further enhance the sealing effect and prevent flue gas leakage, the spring 21 is used to prevent the bolts 18 at the connection points from loosening. This is because vibrations are inevitable during the operation of the desulfurization tower, such as the operation of the water pump 5 and the flow of flue gas. These vibrations subject the bolts 18 to alternating stress. Without the spring 21, the bolts 18 would gradually loosen under the influence of alternating stress. However, the spring 21 undergoes elastic deformation when subjected to vibration, absorbing and buffering the vibration energy. When vibration causes the bolts 18 to loosen, the spring 21 generates a counterforce through its own extension and contraction, preventing the bolts 18 from shifting and maintaining the preload of the bolts 18. This reduces the possibility of the bolts 18 loosening and ensures the connection stability between the inlet pipe 14 and the flue 17. At this time, water pump 5 is started. Under the action of water pump 5, the deacidifying agent solution in water tank 4 flows out from the output end of water tank 4, enters the delivery pipe 7 through the transmission pipe 6, and multiple spray heads 8 fixedly connected to the bottom end of the delivery pipe 7 atomize and spray the deacidifying agent solution into the deacidification tank 2. Then, the atomized deacidifying agent comes into full contact with the flue gas. The inclined plates 9 symmetrically fixedly connected inside the deacidification tank 2 make the flow path of the flue gas in the tank more tortuous, increasing the contact time and contact area between the flue gas and the deacidifying agent. At the same time, the filling layer 10 fixedly connected in the middle of the deacidification tank 2 further increases the gas-liquid contact area, strengthens the mass transfer process, and allows the acidic gas and the deacidifying agent to fully undergo neutralization and other chemical reactions, removing the acidic components in the flue gas. After the deacidification reaction, The flue gas will carry some mist droplets. When the flue gas rises to the top of the deacidification tank 2, the demister installed at the bottom of the arc-shaped top 12 will demist the flue gas, remove the mist droplets, and further purify the flue gas. The purified flue gas after demisting will be discharged from the deacidification tower through the gas outlet pipe 13 fixedly connected to the top of the arc-shaped top 12, completing the entire deacidification process. During the deacidification reaction, some of the deacidification agent solution will absorb acidic gases and become a solution containing acidic substances. These solutions will flow downward in the deacidification tank 2. The bottom of the deacidification tank 2 is fixedly connected to the top of the water tank 4, and an activated carbon plate 11 is fixedly connected at the connection. The activated carbon plate 11 can adsorb some impurities, so that the solution can be recycled.
