Description

Technical Field

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

[0002] A power plant is a power plant that converts some form of primitive energy into electrical energy to supply electricity for fixed facilities or transportation. During the operation of a power plant, desulfurization and denitrification treatment equipment is required to treat the flue gas for desulfurization and denitrification, and the flue gas before desulfurization and denitrification needs to be pretreated to remove impurities.

[0003] However, existing power plant flue gas desulfurization and denitrification equipment is prone to impurities adhering to the filter plates when removing impurities from the flue gas, causing them to become clogged and affecting the filtration operation. In addition, the filter plates are inconvenient to disassemble and assemble.

[0004] To address the aforementioned problems, this application proposes a power plant flue gas desulfurization and denitrification treatment device to solve these problems. Utility Model Content

[0005] In order to solve the problems of impurities adhering to filter plates and inconvenient disassembly and assembly of filter plates in existing power plant flue gas desulfurization and denitrification treatment equipment, the purpose of this utility model is to provide a power plant flue gas desulfurization and denitrification treatment equipment.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a power plant flue gas desulfurization and denitrification treatment equipment, including a treatment device, a Z-shaped pipe and an outlet pipe for use, and a pretreatment mechanism for use fixedly connected to the end of the Z-shaped pipe, and a limiting mechanism for use on the pretreatment mechanism.

[0007] The pretreatment mechanism includes a frame, one side of which is fixedly connected to a Z-shaped tube, and the other side of the frame is connected to a matching inlet pipe. A through slot is formed on one side of the frame, and a sealing plate is hinged within the slot. A slot is formed through the frame, and symmetrically arranged baffles are integrally formed at the top and bottom of the frame's inner cavity. The slot and baffles can slide and insert onto the filter plate. A motor is fixedly installed on the upper side of one side of the frame, and a lead screw is fixedly connected to the end of the motor's output. The lead screw is rotatably inserted into the frame. A U-shaped plate is threaded onto the upper part of the frame. A rotating hole is opened through the upper end of the frame, and a screw is inserted into the rotating hole. A brush that works with the filter plate is fixedly installed on one side of the U-shaped plate, and an elastic plate is fixedly installed on the upper end of the other side of the U-shaped plate. A toothed plate is fixedly installed on the upper end of the inner cavity of the frame, and the elastic plate can make movable contact with the toothed plate. A guide rod is fixedly inserted into the lower end of the frame. An insertion hole is opened through the lower end of the frame, and the guide rod is fixedly inserted into the insertion hole. A guide hole is opened through the lower end of the U-shaped plate, and the guide rod slides through the guide hole.

[0008] Preferably, the limiting mechanism includes a moving block and a fixed block. The moving block is fixedly installed at the top and bottom of one side of the filter plate, and a rotating shaft is rotatably inserted into the moving block. A through hole is provided on the moving block, and the rotating shaft is rotatably inserted into the through hole. A rotating ring is fixedly sleeved on one end of the rotating shaft, and a torsion spring is fixedly installed on one side of the rotating ring. A groove for matching is provided on the outer wall of the rotating ring, and the grooves are distributed in an array. The end of the torsion spring is fixedly connected to the moving block, and a shaped block is fixedly sleeved on the end of the rotating shaft away from the torsion spring. The fixed block is fixedly installed at the top and bottom of the frame, and a shaped groove is provided through the fixed block. The shaped block can slide through the shaped groove, and the inner diameter of the shaped groove is the same as the outer diameter of the shaped block.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. Through the use of the pretreatment mechanism, the U-shaped plate can be driven to move back and forth in a cycle while the filter plate intercepts and filters impurities in the flue gas. This, in turn, drives the brush to move back and forth in a cycle, effectively cleaning the impurities intercepted by the filter plate. This prevents the filter plate from becoming clogged and affecting the flue gas filtration operation. The U-shaped plate will also drive the elastic plate to move back and forth in a cycle, allowing the elastic plate to intermittently contact the protruding parts of the toothed plate and deform and separate. This causes the elastic plate to vibrate intermittently, which in turn drives the brush to vibrate intermittently, thus effectively improving the cleaning effect of the filter plate.

[0011] 2. The use of the limiting mechanism facilitates the convenient rotation and reset of the rotating ring, thereby facilitating the rotation and reset of the irregularly shaped block, and further facilitating the docking and misalignment of the irregularly shaped block and the irregularly shaped groove, thus facilitating the disassembly and assembly of the filter plate.

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

[0020] Example: Figures 1-5 As shown, this utility model provides a power plant flue gas desulfurization and denitrification treatment equipment, including a treatment device 1. The treatment device 1 can draw in the power plant flue gas to be treated and discharge it after desulfurization and denitrification treatment. This is the prior art and will not be described in detail here. The treatment device 1 is provided with a Z-shaped pipe 11 and an outlet pipe 12 for use. The end of the Z-shaped pipe 11 is fixedly connected to a pretreatment mechanism 2 for use. The pretreatment mechanism 2 is provided with a limiting mechanism 3 for use.

[0021] The pretreatment mechanism 2 includes a frame 21. One side of the frame 21 is fixedly connected to a Z-shaped tube 11, and the other side of the frame 21 is connected to a cooperating inlet tube 22. A through groove 214 is opened through one side of the frame 21, and a sealing plate 215 is hinged in the through groove 214. The cooperation between the through groove 214 and the sealing plate 215 facilitates the cleaning of impurities intercepted inside the frame 21. A slot 23 is opened through the frame 21, and symmetrically arranged baffles 24 are integrally formed at the top and bottom of the inner cavity of the frame 21. The slot 23 and the baffles 24 can slide and be inserted into the filter plate 25. A motor 26 is fixedly installed at the upper end of one side of the frame 21, and a lead screw 27 is fixedly connected to the output end of the motor 26. The lead screw 27 is rotatably inserted into the frame 21, and a U-shaped plate 28 is threaded onto the lead screw 27. The upper end of the frame 21 is through... A rotating hole 216 is provided, and a lead screw 27 is rotatably inserted into the rotating hole 216. The rotating hole 216 ensures the stable rotation of the lead screw 27. A brush 29 that works with the filter plate 25 is fixedly installed on one side of the U-shaped plate 28, and an elastic plate 210 is fixedly installed on the upper end of the other side of the U-shaped plate 28. A toothed plate 211 is fixedly installed on the upper end of the inner cavity of the frame 21, and the elastic plate 210 can move in contact with the toothed plate 211. A guide rod 212 is fixedly inserted into the lower end of the frame 21. An insertion hole 217 is provided through the lower end of the frame 21, and the guide rod 212 is fixedly inserted into the insertion hole 217. A guide hole 213 is provided through the lower end of the U-shaped plate 28, and the guide rod 212 slides through the guide hole 213. The cooperation of the insertion hole 217, the guide rod 212 and the guide hole 213 plays a limiting and guiding role in the movement adjustment of the U-shaped plate 28.

[0022] By adopting the above technical solution, during use, the flue gas first enters the frame 21 through the inlet pipe 22 and is intercepted by the filter plate 25. Then, it is introduced into the treatment device 1 through the Z-shaped pipe 11 for desulfurization and denitrification treatment. During this period, the motor 26 drives the lead screw 27 to rotate alternately in the forward and reverse directions, thereby driving the U-shaped plate 28 to move back and forth in a cycle, which in turn drives the brush 29 to move back and forth in a cycle. This effectively cleans the impurities intercepted by the filter plate 25, thus avoiding the phenomenon of filter plate 25 clogging and affecting the flue gas filtration operation. At the same time, the U-shaped plate 28 drives the elastic plate 210 to move back and forth in a cycle, which allows the elastic plate 210 to intermittently contact the protruding part of the toothed plate 211 and deform and separate, which in turn causes the elastic plate 210 to vibrate intermittently, thereby driving the brush 29 to vibrate intermittently, thus effectively improving the cleaning effect of the filter plate 25.

[0023] The limiting mechanism 3 includes a movable block 31 and a fixed block 32. The movable block 31 is fixedly installed on the top and bottom of one side of the filter plate 25, and a rotating shaft 33 is rotatably inserted into the movable block 31. A retaining hole 38 is provided through the movable block 31, and the rotating shaft 33 is rotatably inserted into the retaining hole 38. The retaining hole 38 provides a guarantee for the stable rotation of the rotating shaft 33. A rotating ring 34 is fixedly sleeved on one end of the rotating shaft 33, and a torsion spring 35 is fixedly installed on one side of the rotating ring 34. A matching spring is provided on the outer wall of the rotating ring 34. The grooves 39 are arranged in an array and can increase friction to facilitate operation. The end of the torsion spring 35 is fixedly connected to the moving block 31, and the end of the rotating shaft 33 away from the torsion spring 35 is fixedly fitted with a shaped block 36. The fixed block 32 is fixedly installed at the top and bottom of the frame 21, and a shaped groove 37 is opened through the fixed block 32. The shaped block 36 can slide through the shaped groove 37. The inner diameter of the shaped groove 37 is the same as the outer diameter of the shaped block 36.

[0024] By adopting the above technical solution, during use, hold two rotating rings 34 and insert the corresponding filter plate 25 between the slot 23 and the baffle 24. When the irregular block 36 contacts the corresponding fixed block 32, rotate the two rotating rings 34 by 180 degrees, thereby driving the corresponding rotating shaft 33 to rotate by 180 degrees. This allows the corresponding irregular block 36 to rotate by 180 degrees and twist the corresponding torsion spring 35. Then, fully insert the corresponding filter plate 25 between the slot 23 and the baffle 24. At this time, the irregular block 36 will penetrate the corresponding irregular groove 37. After that, release the two rotating rings 34. At this time, the torsion spring 35 will drive the irregular block 36 to reverse and reset, thereby misaligning the irregular block 36 with the irregular groove 37. This allows the filter plate 25 to be conveniently fixed on the frame 21. During subsequent use, the filter plate 25 can be removed by reversing the above steps.

[0025] Working principle: When in use, hold the two rotating rings 34 and insert the corresponding filter plate 25 between the slot 23 and the baffle 24. When the irregular block 36 contacts the corresponding fixed block 32, rotate the two rotating rings 34 by 180 degrees, which will drive the corresponding rotating shaft 33 to rotate by 180 degrees. This will then allow the corresponding irregular block 36 to rotate by 180 degrees and twist the corresponding torsion spring 35. Then, fully insert the corresponding filter plate 25 between the slot 23 and the baffle 24. At this time, the irregular block 36 will penetrate the corresponding irregular groove 37. After that, release the two rotating rings 34. At this time, the torsion spring 35 will drive the irregular block 36 to reverse and reset, thereby misaligning the irregular block 36 with the irregular groove 37. This will allow the filter plate 25 to be easily fixed on the frame 21. During subsequent use, the filter plate 25 can be removed by reversing the above steps.

[0026] During the flue gas desulfurization and denitrification process in the power plant, the flue gas first enters the frame 21 through the inlet pipe 22 and is intercepted by the filter plate 25. Then, it is introduced into the treatment device 1 through the Z-shaped pipe 11 for desulfurization and denitrification. During this process, the motor 26 drives the lead screw 27 to rotate alternately in the forward and reverse directions, which in turn drives the U-shaped plate 28 to move back and forth in a cycle. This, in turn, drives the brush 29 to move back and forth in a cycle, effectively cleaning the impurities intercepted by the filter plate 25. This prevents the filter plate 25 from becoming clogged and affecting the flue gas filtration operation. At the same time, the U-shaped plate 28 drives the elastic plate 210 to move back and forth in a cycle. This causes the elastic plate 210 to intermittently contact the protruding part of the toothed plate 211 and deform and separate. This causes the elastic plate 210 to vibrate intermittently, which in turn causes the brush 29 to vibrate intermittently, thus effectively improving the cleaning effect of the filter plate 25.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
