Description

Technical Field

[0001] The utility model relates to the technical field of denitration reactors, and more specifically, to a flue gas SCR denitration reactor. Background Art

[0002] Denitrification reactors offer significant environmental advantages, effectively reducing nitrogen oxide emissions and alleviating air pollution. However, in practice, they also face challenges, such as reduced catalyst activity and ammonia slip. Therefore, continuous optimization of denitrification technology is necessary to improve catalyst stability and denitrification efficiency to meet increasingly stringent environmental requirements.

[0003] When general devices are in use, if the door of the denitrification device is not closed tightly, ammonia may leak. Ammonia is a toxic and harmful chemical. If it leaks into the environment, it will not only pose a risk of suffocation or poisoning to on-site workers, but may also cause fire or explosion accidents. Especially if hot work is carried out during maintenance, the explosive mixture formed by the mixture of ammonia and air is more likely to cause catastrophic consequences. Therefore, it needs to be modified and optimized. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figures 1 to 7 As shown, the utility model provides a flue gas SCR denitrification reactor, comprising a support 1 and a shell 2, wherein the shell 2 is fixedly arranged above the support 1;

[0025] A casement door 9 is hinged on one side of the shell 2, and a limit rod 10 is fixedly installed between the upper and lower sides inside the casement door 9. A fixing ring 11 is fixedly sleeved on the middle outer surface of the limit rod 10, and a spring 13 and a spring 2 14 are fixedly installed on the upper and lower sides of the fixing ring 11 respectively. A lifting plate 15 is fixedly installed on the bottom end of the spring 2 14, and the lifting plate 15 is movably sleeved with the limit rod 10. A pressing plate 12 is fixedly installed above the spring 13, and the pressing plate 12 is movably sleeved with the limit rod 10. A fixing plate 16 is fixedly installed on one side of the shell 2, and the fixing plate 16 is movably connected to the pressing plate 12 and the lifting plate 15.

[0026] When the staff uses it, the staff first presses the pressing plate 12 downward and moves the lifting plate 15 upward. When the pressing plate 12 moves downward, the spring 13 is subjected to pressure from top to bottom. When the lifting plate 15 moves upward, the butterfly spring 2 14 is subjected to pressure from bottom to top. When the spring 13 is subjected to pressure from top to bottom, the upper end of the spring 13 is contracted toward the lower end. When the spring 2 14 is subjected to pressure from bottom to top, the bottom end of the spring 2 14 is contracted toward the upper end. When one end of the lifting plate 15 combined with the pressing plate 12 is detached from the fixing plate 16, the swing door 9 can be opened.

[0027] By pressing the pressing plate 12 and moving the lifting plate 15 upward, the spring 13 is contracted from top to bottom and the spring 2 14 is contracted from bottom to top respectively. When the pressing plate 12 and the lifting plate 15 are both separated from the fixing plate 16, the swing door 9 can be opened. Compared with the traditional device, the device fixes the swing door 9 to prevent the swing door 9 from being closed, resulting in an unfixed connection between the swing door 9 and the shell 2, causing the swing door 9 to open, causing the smoke inside the shell 2 to leak out, thereby causing smoke poisoning to the staff, thereby improving the safety of the device operation.

[0028] Among them, one side of the shell 2 is fixedly connected to the air intake pipe 3, the inner side of the air intake pipe 3 is fixedly sleeved with a connecting pipe 4, the outer surface of the air intake pipe 3 is movably installed with an arc sleeve 1 5 and an arc sleeve 2 25, one end of the arc sleeve 1 5 is rotatably installed with a threaded rod 1 6, one end of the threaded rod 1 6 passes through the left and right sides of the arc sleeve 2 25, the threaded rod 1 6 and the arc sleeve 2 25 are threadedly sleeved, one end of the threaded rod 1 6 is fixedly installed with a baffle 7, one side of the arc sleeve 1 5 is fixedly installed with a slide rod 8, one end of the slide rod 8 passes through the left and right sides of the arc sleeve 2 25.

[0029] When the staff uses it, they first rotate the threaded rod 16. When the threaded rod 16 rotates, it will drive the rotation of the baffle 7. Since the connection between the arc sleeve 25 and the threaded rod 16 is provided with the same thread as the threaded rod 16, the arc sleeve 25 will be driven to move as the threaded rod 16 rotates. When the arc sleeve 25 moves, it will slide on the surface of the slide rod 8. When the inner side of the arc sleeve 25 is separated from the surface of the intake pipe 3, the connecting pipe 4 can be removed from the inside of the intake pipe 3.

[0030] By rotating the threaded rod 1 6, the baffle 7 and the arc sleeve 2 25 connected by the thread are driven to move, so that the arc sleeve 25 slides on the slide rod 8 and separates from the surface of the intake pipe 3. When the arc sleeve 25 separates from the surface of the intake pipe 3, the connecting pipe 4 can be removed from the inside of the intake pipe 3. Compared with the traditional device, the device facilitates the fixation of the intake pipe 3 and the connecting pipe 4 by disassembling the intake pipe 3 and the connecting pipe 4, thereby improving the working efficiency of the device and improving the convenience of operation.

[0031] A bottom plate 19 is fixedly installed between two sides of the housing 2 , and a filter cartridge 20 is fixedly installed above the bottom plate 19 .

[0032] The design of the bottom plate 19 and the filter cartridge 20 facilitates fixing the positions of the connecting rod 21 and the filter plate 22 . A connecting plate 17 is fixedly mounted on one side of the filter cartridge 20 .

[0033] A filter plate 22 is fixedly mounted on the bottom of the inner side of the filter cartridge 20 , and a connecting rod 21 is fixedly mounted above the filter plate 22 .

[0034] Through the design of the filter plates 22 and the connecting rods 21 , the filter material is placed between the two filter plates 22 , thereby denitrifying the flue gas.

[0035] A motor 23 is fixedly mounted on the bottom inner side of the housing 2 , and a fan blade 24 is fixedly mounted above the transmission shaft of the motor 23 .

[0036] By starting the motor 23 to drive the fan blades 24 to rotate, the smoke coming from the inside of the air inlet pipe 3 can quickly pass through the inside of the filter cartridge 20.

[0037] An air outlet pipe 18 is fixedly connected to the upper portion of the housing 2 , and the interior of the air outlet pipe 18 is communicated with the interior of the housing 2 .

[0038] Through the design of the exhaust pipe 18 , when the flue gas denitrification is completed, it can be moved out of the interior of the housing 2 through the exhaust pipe 18 .

[0039] The working principle and use process of this utility model:

[0040] When the staff uses it, the staff first presses the pressing plate 12 downward and moves the lifting plate 15 upward. When the pressing plate 12 moves downward, the spring 13 is subjected to pressure from top to bottom. When the lifting plate 15 moves upward, the butterfly spring 2 14 is subjected to pressure from bottom to top. When the spring 13 is subjected to pressure from top to bottom, the upper end of the spring 13 is contracted toward the lower end. When the spring 2 14 is subjected to pressure from bottom to top, the bottom end of the spring 2 14 is contracted toward the upper end. When one end of the lifting plate 15 combined with the pressing plate 12 is detached from the fixing plate 16, the swing door 9 can be opened.

[0041] When the staff uses it, they first rotate the threaded rod 16. When the threaded rod 16 rotates, it will drive the rotation of the baffle 7. Since the connection between the arc sleeve 25 and the threaded rod 16 is provided with the same thread as the threaded rod 16, the arc sleeve 25 will be driven to move as the threaded rod 16 rotates. When the arc sleeve 25 moves, it will slide on the surface of the slide rod 8. When the inner side of the arc sleeve 25 is separated from the surface of the intake pipe 3, the connecting pipe 4 can be removed from the inside of the intake pipe 3.
