Description

Technical Field

[0001] This utility model belongs to the field of flue gas purification technology, and in particular relates to a flue gas purification device for power plants. Background Technology

[0002] A flue gas purification device for power plants refers to an integrated flue gas purification system. Its core function is to remove particulate matter from the flue gas produced by the combustion of boilers in power plants continuously and efficiently, so that its emissions meet or exceed national environmental protection standards.

[0003] After dust removal, existing purification equipment requires cleaning the dust adhering to the plates to prepare for the next operation. The traditional cleaning method is to open the top cover of the purification box and have staff use sticks or other tools to tap the plates to remove the dust particles. However, since the plates inside the purification box are mostly arranged in parallel and connected in series, staff need to tap them one by one. This method not only increases the workload of the staff, but also takes a long time to clean, thus greatly reducing the overall cleaning efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a flue gas purification device for power plants. By setting up a cleaning mechanism, specifically, a motor drives a rotating block to rotate counterclockwise. The rotating block intermittently pushes a second rotating shaft and three rotating plates on it to rotate counterclockwise. Simultaneously, the three rotating plates intermittently push a first rotating plate and a first rotating shaft to rotate clockwise. When the second rotating plate loses contact with the first rotating plate, a spiral spring causes the first rotating plate to rotate counterclockwise to reset. The convex post then impacts the electrode plate, generating vibration and causing dust to fall off. This structure can quickly and efficiently clean the dust adhering to the electrode plate, reducing the workload of workers and effectively improving overall cleaning efficiency. It solves the problem that existing purification devices require cleaning the electrode plates after dust removal. Traditionally, workers often use sticks to strike the electrode plates, but the electrode plates in the purification chamber are mostly arranged in series, which increases the workload of workers and takes a long time, leading to a decrease in overall cleaning efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a flue gas purification device for power plants, comprising a support frame, a purification box fixedly connected inside the support frame, two crossbeams fixedly connected to the inner wall of the purification box, several electrode plates fixedly connected inside the two crossbeams, a funnel fixedly connected to the bottom of the purification box, a square frame fixedly connected to the bottom of the funnel, and a baffle inserted inside the square frame. It also includes: a cleaning mechanism disposed on the front of the interior of the purification box, used to clean particles on the electrode plates; the cleaning mechanism includes a first rotating shaft and a second rotating shaft; a fixing plate fixedly connected to the left side of the electrode plates; several first rotating plates fixedly connected to the outer surface of the first rotating shaft; and three second rotating plates fixedly connected to the outer surface of the second rotating shaft; and a disassembly and assembly mechanism disposed inside the square frame and inside the baffle, used for quickly disassembling and assembling the baffle; several first rotating plates are evenly distributed on the outer surface of the first rotating shaft, and several second rotating plates are evenly distributed in a ring on the outer surface of the second rotating shaft.

[0007] Furthermore, round tubes are fixedly connected to the left and right sides of the purification box, and an electric discharger is installed on the top of the purification box; the electric discharger extends into the interior of the purification box, and both round tubes are interconnected with the interior of the purification box.

[0008] Furthermore, the cleaning mechanism includes a mounting shell fixedly connected to the back of the purification box, a rotating shaft rotatably connected to the inner wall of the purification box, a protruding post fixedly connected to the top of the rotating plate, a spiral spring fixedly connected to the inner wall of the mounting shell, and the other end of the spiral spring fixedly connected to the outer surface of the rotating shaft; the protruding post is made of rubber.

[0009] Furthermore, the disassembly and assembly mechanism includes a receiving groove on the front of the frame, a rotating column is rotatably connected inside the baffle, the rotating column is rotatably connected to the inner wall of the receiving groove, a slot is formed on the outer surface of the rotating column, a ring is fixedly connected to the top of the outer surface of the rotating column, and a slot is formed on the outer surface of the ring.

[0010] Furthermore, the second rotating shaft is rotatably connected to the inner wall of the purification chamber. A turntable is fixedly connected to the front of the second rotating shaft, and three round rods are fixedly connected to the front of the turntable. A support is fixedly connected to the front of the purification chamber, and a motor is fixedly connected inside the support. A rotating block is fixedly connected to the output end of the back of the motor. The three round rods are distributed in a ring at equal intervals on the front of the turntable. The rotation axis of the rotating block does not coincide with the axis of the second rotating shaft, so that when the rotating block rotates in a circle, it will only contact one round rod at a time.

[0011] Furthermore, the baffle has a first circular groove and a second circular groove inside. The outer surface of the ring is rotatably connected to the inner wall of the second circular groove. A second spiral spring is fixedly connected to the inner wall of the first circular groove. The other end of the second spiral spring is fixedly connected to the outer surface of the rotating column. The first circular groove and the second circular groove are interconnected. The rotatable connection between the ring and the second circular groove can prevent the rotating column from dislodging from the interior of the baffle.

[0012] Furthermore, a movable groove is provided inside the frame, and a locking block is slidably limited to the inner wall of the movable groove. A spring is fixedly connected to the right side of the inner wall of the movable groove, and the left end of the spring is fixedly connected to the right side of the locking block. An inclined surface is provided at the left end of the locking block, and the locking block is L-shaped. The L-shaped design of the locking block can prevent it from disengaging from the movable groove.

[0013] Furthermore, a fixed shell is fixedly connected to the front of the baffle, and a sliding limit fitting is provided inside the fixed shell. A limit ring is fixedly connected to the outer surface of the insertion rod, and the outer surface of the limit ring slides and limits the inner wall of the fixed shell.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model, through the setting of a cleaning mechanism, specifically, starts a motor to drive a rotating block to rotate counterclockwise. The rotating block intermittently pushes the second rotating shaft and the three rotating plates on it to rotate counterclockwise. At the same time, the three rotating plates intermittently push the first rotating plate and the first rotating shaft to rotate clockwise. When the second rotating plate loses contact with the first rotating plate, the spring force of the first spiral spring drives the first rotating plate to rotate counterclockwise to reset. The convex post impacts the electrode plate to generate vibration, causing the dust on the electrode plate to fall off. This structure can quickly and efficiently clean the dust attached to the electrode plate, reduce the workload of the staff, and effectively improve the overall cleaning efficiency.

[0016] 2. This utility model features a disassembly and assembly mechanism. Specifically, the insert rod is first pulled forward to release the lock of the rotating column. Then, the baffle is pulled out. At this time, the rotating column rotates around its own axis due to the obstruction of the locking block. When the baffle is fully pulled out, the second spring of the spiral spring drives the rotating column to reset. Then, the insert rod is released, and the second spring pushes the insert rod to reset and insert it into the slot. When the baffle is inserted back, the rotating column squeezes and pushes the locking block to the right. After it is fully inserted, the first spring pushes the locking block to the left to reset and lock the rotating column. This structure allows for quick disassembly and assembly of the baffle, greatly improving the efficiency of cleaning dust from the funnel.

[0030] Please see Figures 1-8As shown, this utility model is a flue gas purification device for power plants, including a support frame 1. A purification box 11 is fixedly connected inside the support frame 1. Two crossbeams 14 are fixedly connected to the inner wall of the purification box 11. Several electrode plates 141 are fixedly connected inside the two crossbeams 14. A funnel 15 is fixedly connected to the bottom of the purification box 11. A square frame 151 is fixedly connected to the bottom of the funnel 15. A baffle 152 is inserted inside the square frame 151. The device also includes a cleaning mechanism 2, which is located on the front of the interior of the purification box 11 and is used to clean particles from the electrode plates 141. The cleaning mechanism 2 includes a first rotating shaft 22 and a second rotating shaft 23. A fixing plate 21 is fixedly connected to the left side of the electrode plate 141.

A disassembly and assembly mechanism 3 is located inside the frame 151 and inside the baffle 152, and is used for quick disassembly and assembly of the baffle 152. Several first rotating plates 221 are evenly distributed on the outer surface of the first rotating shaft 22, and several second rotating plates 231 are evenly distributed in a ring on the outer surface of the second rotating shaft 23. Round tubes 12 are fixedly connected to the left and right sides of the purification box 11, and a discharger 13 is installed on the top of the purification box 11. The discharger 13 extends into the interior of the purification box 11, and both round tubes 12 are interconnected with the interior of the purification box 11. The cleaning mechanism 2 includes a mounting shell 223 fixedly connected to the back of the purification box 11, a rotating shaft 22 rotatably connected to the inner wall of the purification box 11, a protruding post 222 fixedly connected to the top of the rotating plate 221, a spiral spring 224 fixedly connected to the inner wall of the mounting shell 223, and the other end of the spiral spring 224 fixedly connected to the outer surface of the rotating shaft 22; the protruding post 222 is made of rubber. The disassembly and assembly mechanism 3 includes a receiving groove 31 opened on the front of the square frame 151, a rotating column 32 rotatably connected inside the baffle 152, the rotating column 32 rotatably connected to the inner wall of the receiving groove 31, a slot 321 opened on the outer surface of the rotating column 32, a ring 322 fixedly connected to the top of the outer surface of the rotating column 32, and a slot 323 opened on the outer surface of the ring 322.The second rotating shaft 23 is rotatably connected to the inner wall of the purification box 11. A turntable 232 is fixedly connected to the front of the second rotating shaft 233, and three round rods 233 are fixedly connected to the front of the turntable 232.

A rotating block 242 is fixedly connected to the output end of the back of the motor 241. When the motor 241 is started, it drives the rotating block 242 to rotate counterclockwise. The rotating block 242 will intermittently push the second rotating shaft 23 and the three rotating plates 231 on it to rotate counterclockwise. At the same time, the three rotating plates 231... It will also intermittently push the rotating plate 221 and the rotating shaft 22 to rotate clockwise. When the rotating plate 231 loses contact with the rotating plate 221, the spiral spring 224 will cause the rotating plate 221 to rotate counterclockwise to reset. It will also cause the plate 141 to vibrate by impacting it through the protrusion 222, causing the dust on the plate 141 to fall off. This structure can quickly and efficiently clean the dust attached to the plate 141, reduce the workload of the staff, and effectively improve the overall cleaning efficiency. The three round rods 233 are distributed in a ring at equal intervals on the front of the turntable 232.

[0031] The baffle 152 has a first circular groove 33 and a second circular groove 331 inside. The outer surface of the ring 322 is rotatably connected to the inner wall of the second circular groove 331. A second spiral spring 34 is fixedly connected to the inner wall of the first circular groove 33. The other end of the spiral spring 34 is fixedly connected to the outer surface of the rotating column 32. The first circular groove 33 and the second circular groove 331 are interconnected. The frame 151 has a movable groove 35 inside. A locking block 351 is slidably limited to the inner wall of the movable groove 35. A first spring 352 is fixedly connected to the right side of the inner wall of the movable groove 35. The left end of the first spring 352 is fixedly connected to the right side of the locking block 351. The left end of the locking block 351 has an inclined surface and the locking block 351 is L-shaped. A fixed housing 36 is fixedly connected to the front of the baffle 152. A sliding limit fitting is provided inside the fixed housing 36, and a limit ring 362 is fixedly connected to the outer surface of the rod 361. The outer surface of the limit ring 362 slides and limits the movement against the inner wall of the fixed housing 36. A second spring 363 is sleeved on the outer side of the rod 361. One end of the back of the second spring 363 is fixedly connected to the front of the limit ring 362, and one end of the front of the second spring 363 is fixedly connected to the inner wall of the fixed housing 36. The rod 361 is inserted into the slot 323. First, pull the rod 361 forward to release the lock of the rotating column 32, then pull out the baffle 152. At this time, the rotating column 32 rotates on its own axis due to the obstruction of the locking block 351. When the baffle 152 is completely pulled out, the second spiral spring 34 drives the rotating column 32 to reset. Then, the insertion rod 361 is released, and the second spring 363 pushes the insertion rod 361 to reset and insert it into the slot 323. When the baffle 152 is inserted back, the rotating column 32 squeezes and pushes the locking block 351 to the right. After it is fully inserted, the first spring 352 pushes the locking block 351 to the left to reset and lock the rotating column 32. This structure can quickly disassemble and assemble the baffle 152, which greatly improves the efficiency of cleaning dust in the funnel 15.

[0032] A specific application of this embodiment is as follows: During use, smoke enters the purification chamber 11 through the left circular pipe 12, and at the same time, the discharger 13 is turned on to charge the smoke and dust, which is then adsorbed and captured by the electrode plate 141. The smoke after dust removal is discharged to the next process through the right circular pipe 12. After dust removal is completed, the motor 241 is started to drive the rotating block 242 to rotate counterclockwise. During the rotation of the rotating block 242, it pushes the circular rod 233 in contact with it, thereby causing the turntable 232 to drive the rotating shaft 23 and the three rotating plates 231 on its outer surface to rotate counterclockwise together. During this process, when the rotating plate 231 contacts the rotating plate 221, it will push it and the rotating shaft 22 to rotate clockwise together. At this time, the spiral spring 224 is compressed. 31 continues to rotate until it loses contact with the rotating plate 221. The worm spring 224 then drives the rotating shaft 22 to rotate counterclockwise and reset. At this time, the rotating plate 221 rotates and impacts the fixed plate 21 through the protrusion 222, transmitting the vibration to the electrode plate 141, causing the dust particles attached to it to fall off. Meanwhile, as the rotating block 242 continues to rotate, it will first lose contact with the round rod 233 and then contact the new round rod 233, thereby achieving the purpose of driving the rotating shaft 23 to rotate counterclockwise intermittently. At the same time, as the rotating plate 231 continues to rotate, it will first lose contact with the rotating plate 221 and then contact the new rotating plate 231 again, thereby achieving the purpose of driving the rotating shaft 22 to rotate clockwise intermittently.

[0033] The detached dust is collected by funnel 15. Then, the insert rod 361 is pulled forward to disengage it from slot 323. At this time, spring 363 is compressed. Next, baffle 152 is pulled out. During this process, because slot 321 is blocked by locking block 351, rotating column 32 rotates clockwise around its own axis, allowing it to smoothly leave receiving slot 31. At this time, spiral spring 34 is stretched until rotating column 32 is completely out of receiving slot 31. Then, the elastic force of spiral spring 34 drives rotating column 32 to rotate counterclockwise to reset. When the insertion rod 361 is released, the spring 363 pushes the insertion rod 361 back to its original position and inserts it into the slot 323. After cleaning the dust in the funnel 15, the baffle 152 is inserted back into its original position. When the rotating column 32 enters the receiving groove 31, it will squeeze the inclined surface of the locking block 351 and push it to the right. At this time, the spring 352 is squeezed. When the baffle 152 is fully inserted back, the spring 352 pushes the locking block 351, which has lost its squeeze, back to its original position and enters the slot 321. At this time, the rotating column 32 is locked by the insertion rod 361, so that the baffle 152 cannot be pulled out.

[0034] It should be noted that the control of motor 241 in this application can all be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be set using existing technologies, such as PLC.
