Description

Technical Field

[0001] This utility model relates to the field of flue gas treatment technology, and in particular to a flue gas desulfurization and denitrification device. Background Technology

[0002] In industrial production processes, the combustion of fossil fuels such as coal and oil produces large amounts of flue gas, which typically contains harmful substances such as sulfur dioxide and nitrogen oxides, causing serious environmental pollution. To reduce the environmental damage caused by these harmful substances, flue gas desulfurization and denitrification technologies have emerged.

[0003] Traditional flue gas desulfurization and denitrification devices mostly treat flue gas by spraying chemical solutions. However, filter plates are prone to clogging during the treatment process, which affects the desulfurization and denitrification effect. Furthermore, filter plate replacement and maintenance are relatively difficult and inconvenient to use. Utility Model Content

[0008] Preferably, the cleaning mechanism includes a linkage shaft that is rotatably connected to the linkage shaft, a linkage groove is provided at the top of the linkage shaft, and a cleaning rod located below the filter plate is fixedly installed on the outer wall of the linkage shaft.

[0009] Preferably, all four positioning blocks are adapted to the four positioning slots.

[0011] Preferably, the linkage rod is adapted to the linkage groove, and the linkage rod is a square rod.

[0012] The beneficial effects of this utility model are:

[0013] By setting up a spraying mechanism and a cleaning mechanism, the spraying pipe can be rotated to spray liquid from the nozzle to desulfurize and denitrify the flue gas. At the same time, the cleaning rod can be rotated to clean impurities on the filter plate to prevent clogging. After the flue gas is treated, the filter plate is easy to replace and maintain, making it convenient to use. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4A flue gas desulfurization and denitrification device includes a transparent housing 1. An inlet pipe 12, connected to the interior of the transparent housing 1, is used to introduce the flue gas to be treated for initial contact. Four positioning slots 14 are provided on the top of the transparent housing 1. A filter plate 17 is installed inside the transparent housing 1, positioned above the inlet pipe 12. Four positioning blocks 16 are fixedly installed on the outer wall of the filter plate 17, each of which is compatible with one of the positioning slots 14, ensuring the filter plate 17 is securely installed inside the transparent housing 1 to prevent displacement. A liquid spraying mechanism is provided on the transparent housing 1. The liquid spraying mechanism includes fixing blocks 2 fixedly installed on the outer wall of the transparent housing 1. Two hydraulic cylinders 3 are fixedly installed on the top of each fixing block 2, and the hydraulic cylinders 3 are used to drive the liquid spraying mechanism to move up and down, achieving flexible operation adjustment. A cover plate 4 is fixedly installed on the telescopic end of each cylinder 3. A spray pipe 11 rotatably connected to the cover plate 4 is installed through the cover plate 4. A motor 5 is fixedly installed on the top of the cover plate 4. The motor 5 provides rotational power to drive the rotation of the spray pipe 11, thereby achieving uniform spraying of liquid. A first gear 6 is fixedly installed on the output shaft of the motor 5. A second gear 7 is fixedly installed on the outer wall of the spray pipe 11. The first gear 6 and the second gear 7 are meshed and connected. An inlet pipe 8 is provided above the spray pipe 11. The inlet pipe 8 is used to deliver the treatment liquid to the spray pipe 11 to ensure a continuous liquid supply. A linkage rod 15 is fixedly installed at the bottom of the spray pipe 11. A rotary joint 9 is provided between the inlet pipe 8 and the spray pipe 11. Multiple nozzles 13 located below the cover plate 4 are provided on the spray pipe 11.

[0021] A cleaning mechanism is provided on the filter plate 17. The cleaning mechanism includes a linkage shaft 18 that is rotatably connected to the linkage shaft 18. The rotation of the linkage shaft 18 is damped, so that the linkage rod 15 can cooperate with the linkage groove 20. The top of the linkage shaft 18 is provided with the linkage groove 20. A cleaning rod 19 located below the filter plate 17 is fixedly installed on the outer wall of the linkage shaft 18. The linkage rod 15 is adapted to the linkage groove 20. The linkage rod 15 is a square rod, so that the linkage rod 15 can drive the linkage shaft 18 to rotate.

[0022] In use, this invention involves simultaneously activating two hydraulic cylinders 3 to move the cover plate 4 upwards (synchronous activation of the two hydraulic cylinders 3 is existing technology; for example, a dedicated synchronization controller can be used. This controller can receive signals from sensors or preset programs and precisely control the piston speed and position of each hydraulic cylinder to ensure synchronized movement; or each hydraulic cylinder 3 can be equipped with a proportional valve or servo valve, which can adjust the flow rate and pressure of the oil 3 according to the control signal, thereby achieving precise control of the movement of the hydraulic cylinder 3, as is well known to those skilled in the art). After the cover plate 4 moves upwards to a certain height, the four positioning blocks 16 on the filter plate 17 respectively cooperate with the four positioning slots 14, as shown in the attached diagram. Figure 2As shown, the cover plate 4 is then moved downwards by the hydraulic cylinder 3. After the cover plate 4 moves downwards and comes into tight contact with the top of the transparent box 1, it will not rotate without external force due to the damping caused by the rotation of the linkage shaft 18. Therefore, the linkage rod 15 on the spray pipe 11 can cooperate with the linkage groove 20 to introduce flue gas into the air inlet pipe 12. Then, the motor 5 is started, and by setting the first gear 6 and the second gear 7, the spray pipe 11 can be rotated. The treatment liquid is introduced into the spray pipe 11 through the liquid inlet pipe 8 and the rotary joint 9, and finally... Then, the liquid is sprayed from the nozzle 13 on the rotating spray pipe 11, which can desulfurize and denitrify the flue gas filtered by the filter plate 17, expand the treatment area, and finally discharge the treated flue gas from the exhaust pipe 10. When the spray pipe 11 rotates, the linkage rod 15 and the linkage shaft 18 rotate accordingly. By setting the cleaning rod 19, the impurities on the lower surface of the filter plate 17 can be cleaned to prevent the filter plate 17 from becoming blocked. After the treatment is completed, the cover plate 4 is moved upward again, which can directly remove the filter plate 17, making it easy to replace or repair it.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
