Description

Technical Field

[0001] This utility model belongs to the field of flue gas desulfurization and denitrification, specifically a desulfurization and denitrification device. Background Technology

[0002] Nowadays, industrial processes generate large amounts of waste gas and flue gas, which contain a large number of pollutants harmful to the atmosphere. Nitrogen oxides and sulfur oxides are among the main sources of air pollution. Therefore, before the flue gas is emitted, it needs to be treated by purification equipment to remove sulfur and nitrates to meet safety standards. Existing flue gas desulfurization and denitrification equipment mainly uses spraying to mix the treatment liquid with the flue gas. Patent CN220738024U, entitled "An Adjustable Flue Gas Desulfurization and Denitrification Equipment", discloses a device for rotating spraying treatment liquid. However, in use, the lack of baffle components in the tank results in a short residence time of the flue gas in the tank and incomplete reaction. Therefore, we designed a desulfurization and denitrification equipment to extend the mixing reaction time. Utility Model Content

[0004] This utility model is achieved through the following technical solution:

[0005] A desulfurization and denitrification device includes a tank body with an exhaust port at the top and an air inlet at the bottom. Several support legs are fixedly mounted on the bottom side of the tank body, and a drain pipe is fixedly connected to the bottom of the tank body. A vertical pipe is rotatably mounted inside the tank body, and a drive mechanism for driving the vertical pipe to rotate is provided outside the tank body. The top end of the vertical pipe is rotatably mounted on the tank body and passes through the tank body to connect with an external liquid inlet pipe. A spray pipe is fixedly connected to the vertical pipe, and several spray nozzles are fixedly connected to the spray pipe. Several staggered baffles are fixedly mounted inside the tank body, and the spray pipe is located below the topmost baffle. The vertical pipe is rotatably mounted on the baffle through bearings and passes through the baffles in sequence.

[0006] As described above, in a desulfurization and denitrification device, the drive mechanism includes a motor, which is fixedly mounted on the tank body. The output shaft of the motor is fixedly connected to a coaxial first bevel gear. A second bevel gear is meshed with one side of the first bevel gear, and the second bevel gear is fixedly mounted on the outer periphery of the vertical pipe extending out of the tank body.

[0007] As described above, in a desulfurization and denitrification device, the motor, the first bevel gear, and the second bevel gear are provided with protective covers on their outer peripheries. The protective covers are fixedly installed on the tank body, and the top end of the vertical pipe passes through the protective cover and is connected to the external liquid inlet pipe through a sealed bearing.

[0008] As described above, in a desulfurization and denitrification device, C-shaped scrapers are respectively provided below the baffle plate. The outer side of the C-shaped scraper slides in contact with the inner wall of the tank and the surface of the baffle plate. The C-shaped scrapers are rotatably mounted on the vertical pipe through one-way bearings.

[0009] In the desulfurization and denitrification equipment described above, the bottom of the C-shaped scraper located below the bottom baffle plate slides in contact with the inner wall of the bottom funnel structure of the tank.

[0010] In the desulfurization and denitrification equipment described above, stirring rods are fixedly installed at the middle and bottom outer periphery of the vertical pipe.

[0011] The advantages of this invention are: It has a simple structure and ingenious design.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] A desulfurization and denitrification device, such as Figure 1 As shown, the device includes a tank body 1, with an exhaust port 2 at the top and an air inlet 3 at the bottom. Several support legs 4 are fixedly mounted on the bottom side of the tank body 1. A drain pipe 5 is fixedly connected to the bottom of the tank body 1. A vertical pipe 6 is rotatably mounted inside the tank body 1, and the tank body 1 and the vertical pipe 6 are coaxially arranged. A drive mechanism for rotating the vertical pipe 6 is provided outside the tank body 1. The top end of the vertical pipe 6 is rotatably mounted on the tank body 1 and passes through the tank body 1 to connect with an external liquid inlet pipe. A spray pipe 7 is fixedly connected to the vertical pipe 6, and several nozzles 8 are fixedly connected to the spray pipe 7. Several staggered baffles 9 are fixedly mounted inside the tank body 1. In this embodiment, there are three baffles 9. The spray pipe 7 is located below the topmost baffle 9. The vertical pipe 6 is rotatably mounted on the baffle 9 via bearings and passes through the baffles 9 in sequence. This utility model has a simple structure and ingenious design. By setting staggered baffles 9 in conjunction with rotating spray pipes 7, the mixing reaction time is extended, the mixing effect is increased, and the market demand is met, making it suitable for promotion. When using this utility model, the treatment liquid is first delivered into the vertical pipe 6 through the liquid inlet pipe, and the vertical pipe 6 is driven to rotate by the drive mechanism. The rotation of the vertical pipe 6 can drive the spray pipe 7 and the nozzle 8 to rotate, which can achieve rotational spraying and also play a stirring role. During the process of conveying flue gas from the bottom to the top, the staggered baffles 9 can increase the propagation path, prolong the mixing reaction time of flue gas and treatment liquid, and increase the mixing effect. The treated flue gas is discharged from the exhaust port 2 from the tank 1.

[0017] Specifically, as shown in the figure, the driving mechanism in this embodiment includes a motor 20, which is fixedly mounted on the tank body 1. The output shaft of the motor 20 is fixedly connected to a coaxial first bevel gear 21. A second bevel gear 22 is meshed with one side of the first bevel gear 21. The second bevel gear 22 is fixedly mounted on the outer periphery of the vertical tube 6 extending out of the tank body 1, and is coaxial with the vertical tube 6. The output shaft of the motor 20 drives the first bevel gear 21 to rotate, and the first bevel gear 21 drives the vertical tube 6 to rotate through the second bevel gear 22.

[0018] Specifically, as shown in the figure, in this embodiment, the motor 20, the first bevel gear 21, and the second bevel gear 22 are provided with protective covers 30 on their outer peripheries. The protective covers 30 are fixedly installed on the tank body 1. The top end of the vertical pipe 6 passes through the protective cover 30 and is connected to the external liquid inlet pipe through a sealed bearing 31. The external liquid inlet pipe is fixedly connected to the outer periphery of the sealed bearing 31, and the outer periphery of the sealed bearing 31 is fixedly installed on the protective cover 30. The inner periphery of the sealed bearing 31 is fixedly connected to the vertical pipe 6. The protective cover 30 can protect the internal transmission mechanism, and the sealed bearing 31 can prevent water vapor from entering the protective cover 30 while ensuring that the external liquid inlet pipe does not rotate.

[0019] Furthermore, as shown in the figure, in this embodiment, C-shaped scrapers 40 are respectively provided below the baffle 9. The outer side of the C-shaped scraper 40 slides in contact with the inner wall of the tank 1 and the surface of the baffle 9. The C-shaped scrapers 40 are rotatably mounted on the vertical pipe 6 through one-way bearings 41. When the vertical pipe 6 rotates in the opposite direction, the C-shaped scrapers 40 can be driven by the one-way bearings 41 to clean the residues adhering to the inner wall of the tank 1 and the surface of the baffle 9.

[0020] Furthermore, as shown in the figure, in this embodiment, the bottom of the C-shaped scraper 40 located below the bottom baffle 9 slides in contact with the inner wall of the bottom funnel structure of the tank 1. When the bottom C-shaped scraper 40 rotates, it can clean the inner wall of the bottom funnel of the tank 1.

[0021] Furthermore, as shown in the figure, stirring rods 60 are fixedly installed at the middle and bottom outer periphery of the vertical pipe 6 in this embodiment. The stirring rods 60 can increase the mixing effect of flue gas and treatment liquid.
