Technical Field
[0001] The utility model relates to the technical field of baffle doors, in particular to a flue gas desulfurization baffle door. Background Art
[0002] The flue gas desulfurization baffle door is an important device used in the flue gas desulfurization system, mainly used to control the flow of flue gas and isolate it.

Therefore, the utility model proposes a flue gas desulfurization baffle door. Summary of the Utility Model

Such a design makes it very convenient to replace the new main protection shell and the secondary protection shell II, without the need to replace the entire baffle door, which helps to save costs because only the damaged protection component needs to be replaced instead of the entire door body.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0027] As Figure 1 - Figure 4 shown, this embodiment provides a technical solution: a flue gas desulfurization baffle door, including a frame 1, an air inlet assembly 2 is arranged at the top of the frame 1, a sealing assembly 3 is arranged on the frame 1, a transmission assembly 4 is arranged on one side of the sealing assembly 3, and a protection assembly 5 is arranged on the sealing assembly 3; as Figure 1 shown, the air inlet assembly 2 includes a fan 21 and a ventilation pipe 22. The fan 21 is fixedly connected to the top of the frame 1, the ventilation pipe 22 is fixedly communicated between the frame 1 and the fan 21, and the fan 21 is communicated with the inside of the frame 1 through the ventilation pipe 22; as Figure 1 - Figure 2As shown in the figure, the sealing assembly 3 includes a front baffle 32 and a rear baffle 33. The front baffle 32 is arranged inside the frame 1, and the rear baffle 33 is arranged on one side inside the frame 1 away from the front baffle 32. Rotating shafts 31 are fixedly connected to both the front baffle 32 and the rear baffle 33. The front baffle 32 and the rear baffle 33 are rotatably connected to the frame 1 through the rotating shafts 31. By installing the frame 1 on an external flue gas duct, the rotating shafts 31 enable the front baffle 32 and the rear baffle 33 to rotate inside the frame 1. The rotating shaft 31 cooperates with the front baffle 32 to seal the inside of the frame 1, so that the front baffle 32 isolates the flue gas inside the flue gas duct, and the rear baffle 33 isolates the inside of the frame 1 from the flue gas duct. If the air pressure inside the flue gas duct is greater than the air pressure inside the frame 1 at this time, the front baffle 32 and the rear baffle 33 may be damaged by the acting force of the air pressure. At this time, the fan 21 is started, and the fan 21 sends external air into the inside of the frame 1 along the ventilation pipe 22, thereby adjusting the air pressure inside the frame 1 to keep the air pressure between the flue gas duct and the inside of the frame 1 balanced. Thus, the problem that the front baffle 32 and the rear baffle 33 may be deformed or damaged due to the acting force of the air pressure is solved, which is beneficial to improving the stability of the baffle door during use.
[0028] Furthermore, as Figure 2 shown in the figure, the number of rear baffles 33 arranged inside the frame 1 is two. A sealing plate 34 is fixedly connected to one side inside the frame 1 close to the rear baffle 33. The frame 1 is snap-connected to the rear baffle 33 through the sealing plate 34. By the cooperation of the rear baffle 33 and the sealing plate 34, when the rear baffle 33 is closed, the rear baffle 33 fits with the sealing plate 34 to seal the inside of the frame 1, preventing gas from discharging inside the frame 1 and keeping the air pressure inside the frame 1 stable.
[0029] Furthermore, as Figure 3 shown in the figure, the transmission assembly 4 includes a motor 41 and a driven wheel 42. The motor 41 is fixedly connected to one side of the frame 1, and a driving wheel 44 is fixedly connected to the output end of the motor 41. The driven wheel 42 is fixedly connected to one end of the rotating shaft 31 close to the motor 41. A transmission belt 43 is connected between the driven wheel 42 and the driving wheel 44. By using the driven wheel 42 and the transmission belt 43 for transmission connection, when the motor 41 is started, the motor 41 drives the motor 41 and the driven wheel 42 to rotate through the driving wheel 44, and the driven wheel 42 drives the front baffle 32 and the rear baffle 33 to rotate simultaneously through the rotating shaft 31, thereby realizing the unified control of the front baffle 32 and the rear baffle 33, which is beneficial to simplifying the operation process.
[0030] Furthermore, as Figure 3As shown in the figure, a limit post 45 is rotatably connected to the frame 1, and the limit post 45 is in transmission connection with the transmission belt 43. By installing the limit post 45 on the frame 1 and making the limit post 45 press against the transmission belt 43, the transmission belt 43 is kept in a tight state and closely attached to the driven wheel 42, thereby ensuring the transmission between the driven wheel 42 and the transmission belt 43.
[0031] Furthermore, as Figure 4 shown, a gasket 36 is fixedly connected to one side of the front baffle 32, and a sealing groove 35 matching the gasket 36 is formed on the side of the front baffle 32 away from the gasket 36. By closing the front baffle 32, at this time, the gaskets 36 on multiple front baffles 32 are in mutual fit with the sealing grooves 35, sealing the interior of the frame 1 and preventing flue gas from leaking through the gaps between the front baffles 32.
[0032] To solve the problem that the corrosive substances contained in the flue gas corrode the front baffle 32, resulting in damage to the front baffle 32, as Figure 4 shown, the protection assembly 5 includes a main protection shell 51 and a secondary protection shell 52. The secondary protection shell 52 is arranged on the front baffle 32. A slider 55 is fixedly connected to one side of the front baffle 32 close to the secondary protection shell 52, and a sliding groove 56 is formed on the side of the secondary protection shell 52 close to the slider 55. The secondary protection shell 52 is slidably connected to the front baffle 32 through the slider 55 and the sliding groove 56. The main protection shell 51 is arranged on the secondary protection shell 52. A slider 53 is fixedly connected to one side of the main protection shell 51 close to the secondary protection shell 52, and a sliding groove 54 is formed on the side of the secondary protection shell 52 close to the slider 53. The main protection shell 51 is slidably connected to the secondary protection shell 52 through the slider 53 and the sliding groove 54. By installing the main protection shell 51 and the secondary protection shell 52 on the front baffle 32, the main protection shell 51 and the secondary protection shell 52 protect the front baffle 32 from being easily corroded by corrosive substances, which is beneficial to improving the service life of the baffle door. When the main protection shell 51 and the secondary protection shell 52 are corroded, push the main protection shell 51 to make the main protection shell 51 slide along the sliding groove 54 through the slider 53, remove the main protection shell 51, and then push the secondary protection shell 52 to make the secondary protection shell 52 slide along the slider 55 through the sliding groove 56, remove the secondary protection shell 52, so as to facilitate the replacement of the new main protection shell 51 and the secondary protection shell 52, and avoid the need to replace the entire baffle door when the protection assembly 5 is damaged, which helps to save costs.
[0033] Working principle: When in use: First, install the frame 1 on the external flue gas pipeline, drive-connect the driven wheel 42 with the transmission belt 43, start the motor 41, the motor 41 drives the motor 41 and the driven wheel 42 to rotate through the driving wheel 44, the driven wheel 42 drives the front baffle 32 and the rear baffle 33 to rotate simultaneously through the rotating shaft 31, close the front baffle 32 and the rear baffle 33. At this time, the gaskets 36 on the multiple front baffles 32 are mutually attached to the sealing grooves 35, and the rear baffle 33 is attached to the sealing plate 34, thereby sealing the interior of the frame 1. After that, the front baffle 32 blocks the flue gas on the outside. If the air pressure inside the flue gas pipeline is greater than the air pressure inside the frame 1, start the fan 21, the fan 21 conveys air into the interior of the frame 1, adjusts the air pressure inside the frame 1, and keeps the air pressure in the flue gas pipeline and the interior of the frame 1 balanced.
