Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, specifically to an intelligent dust removal device for treating waste gas from coal-fired power plants. Background Technology

[0002] Coal-fired power plants generate a large amount of flue gas during power generation, which contains harmful substances such as particulate matter, sulfur dioxide, and nitrogen oxides. The emission of these substances not only pollutes the atmospheric environment but also threatens human health. Therefore, in order to protect the environment and human health, coal-fired power plants need to adopt effective exhaust gas dust removal devices to reduce the emission of harmful substances. Existing dust removal methods include electrostatic dust removal, bag dust removal, and spray dust removal. Spray dust removal involves spraying water mist with specific chemical substances, which combines with pollutants in the flue gas to achieve the purpose of exhaust gas treatment.

[0003] In the environmental practice of spray dust removal, in order to utilize water resources efficiently and sustainably, filters are usually used to separate dust and water from the exhaust gas, extract and recycle water from the mixture. As the core component of water recycling, the continuous and efficient operation of the filter is crucial to maintaining the performance of the entire spray dust removal system. However, in actual operation, it is often difficult for staff to monitor the working status of the filter in real time. This not only requires staff to conduct more frequent troubleshooting and repairs, increasing maintenance and time costs and reducing overall operating efficiency, but also affects the cleanliness of the spray dust removal water resources when the filter is clogged or damaged and is used for a long time without timely maintenance or replacement, thus reducing the overall performance of the spray dust removal system.

[0004] Therefore, this invention proposes an intelligent dust removal device for treating exhaust gas from coal-fired power plants to solve the above problems. Summary of the Invention

A drive motor is fixedly connected to the side of the drive shaft away from the first bevel gear, and a support frame is fixedly connected to the drive motor, with the support frame fixedly connected to the outer wall of the dust collector. The dust cleaning and collection mechanism is used to clean the surface of the filter plate and intermittently drive the rotating shaft to rotate.

[0010] As a further aspect of the present invention: a drainage hole is provided on the outer surface of the hollow column, and a shielding ring is fitted on the outer surface of the hollow column, the shielding ring being initially located at the drainage hole.

[0011] As a further embodiment of the present invention: a fixing plate is fixedly connected to one side of the outer surface of the shielding ring, a sliding groove is provided on the side of the fixing plate away from the shielding ring, a lever is slidably connected in the sliding groove, a lever plate is fixedly connected to the end of the lever away from the sliding groove, a rotating shaft is fixedly connected to one side of the lever plate, and the rotating shaft is rotatably connected to the dust collection box.

[0012] As a further aspect of the present invention: a partition is fixedly connected inside the hollow column, a hole is provided at the center of the partition, a baffle is symmetrically attached to the lower end face of the partition, and a sliding column is fixedly connected to the opposite side of the two baffles, and the sliding column is slidably connected to the hollow column.

[0013] As a further aspect of the present invention: each of the sliding columns is fixedly connected to a connecting block at the end away from the baffle, and each of the connecting blocks is rotatably connected to an elastic linkage plate at the lower end face, and each of the elastic linkage plates is rotatably connected to the upper end face of the shielding ring at the end away from the connecting block.

[0014] As a further embodiment of the present invention: an elastic telescopic plate is fixedly connected to the outer surface of the drive shaft near the drive motor, a lever is fixedly connected to the elastic telescopic plate away from the drive shaft, a lifting column is provided on one side of the drive shaft, a support block is slidably connected to the outer surface of the lifting column, the support block is fixedly connected to the side wall of the dust collector, and a groove is provided on the outer surface of the lifting column near the lever, the groove and the lever being compatible.

[0015] As a further embodiment of the present invention: a rack plate is fixedly connected to the lower end of the lifting column, a spring is fixedly connected between the upper surface of the rack plate and the lower surface of the support block, the spring is sleeved on the outer surface of the lifting column, and a sector gear is meshed with the rack plate near the rotating shaft, the sector gear is fixedly connected to the rotating shaft.

[0016] Compared with the prior art, the present invention provides an intelligent dust removal device for treating exhaust gas from coal-fired power plants, which has the following beneficial effects:

[0017] 1. The system features a real-time filtration efficiency monitoring mechanism that periodically weighs the water filtered by the filter plates. Based on the weight of the filtered water within a specified time, staff can monitor the filter plates' operational status in real time, including their filtration efficiency and clogging levels. This not only reduces unnecessary troubleshooting and repairs, thus lowering maintenance and time costs, but also allows for timely maintenance or replacement of clogged or damaged filter plates. This ensures the continuous and efficient operation of the spray dust removal system, improving overall operational efficiency. Furthermore, the timely detection of filter plate clogging or damage through periodic weighing prevents prolonged use of filter plates that have not been maintained or replaced in a timely manner, thereby reducing the entry of impurities and particulate matter into the spray dust removal system, ensuring water cleanliness, and ultimately improving the overall performance of the spray dust removal system.

[0018] 2. Through the setting of elastic linkage plate, connecting block, sliding column and baffle, it is possible to prevent the water resources filtered by the filter plate from entering the hollow column and mixing with the weighed water resources during the discharge process. If the subsequent water resources are mixed with the weighed water resources during discharge, it will lead to inaccurate subsequent weighing data and will not be able to truly reflect the actual working status of the filter plate. This ensures that the water resources discharged each time are accurately weighed and provides reliable data support.

[0019] 3. The dust collection and cleaning mechanism drives the cleaning box and scraper to rotate against the filter plate surface, ensuring that every part of the filter plate is effectively cleaned. Compared with traditional manual cleaning or fixed-position cleaning, this rotating cleaning method can more comprehensively cover the filter plate surface and improve cleaning efficiency. Moreover, by automatically driving the cleaning box and scraper to rotate against the filter plate surface, the frequency and intensity of manual cleaning can be reduced, thereby reducing maintenance costs and ensuring the filtration effect of the filter plate.

[0020] 4. Through the installation of elastic telescopic plates, levers, lifting columns, springs, racks, and sector gears, the rotating shaft can be intermittently driven during the timed cleaning of the filter plate surface, thereby discharging water from inside the hollow column. This not only automates cleaning and discharge, reducing reliance on manual operation, but also automatically discharges water from inside the hollow column while cleaning the filter plate surface at regular intervals, improving work efficiency and ease of operation. Furthermore, the intermittent rotation of the rotating shaft allows for precise control of the timing of water discharge, improving the accuracy of weighing the filtered water to determine the working status of the filter plate.

[0032] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0033] This embodiment describes an intelligent dust removal device for treating exhaust gas from a coal-fired power plant, such as... Figure 1 - Figure 7 As shown, it includes a dust collection box 1, an air inlet 2 fixedly connected to the side wall of the dust collection box 1, a filter plate 3 fixedly connected inside the dust collection box 1, the filter plate 3 being located below the air inlet 2, and also includes a real-time filtration effect detection mechanism and a dust cleaning and collection mechanism.

[0034] In this embodiment, as Figure 2 and Figure 5 As shown, the real-time filtration effect detection mechanism includes a flow guide ring 401, a hollow column 402, a weighing plate 415, and a gravity sensor 416. The flow guide ring 401 is fixedly connected to the lower end face of the filter plate 3, the hollow column 402 is fixedly connected to the lower end of the flow guide ring 401, the gravity sensor 416 is fixedly connected to the lower end face of the weighing plate 415, and the gravity sensor 416 is fixedly connected to the bottom of the hollow column 402. The real-time filtration effect detection mechanism is used to detect the filtration effect of the filter plate 3 during the operation of the filter plate 3 to determine its working status.

[0035] When the filter plate 3 filters the water that is combined with the exhaust gas, the filtered water flows into the hollow column 402 through the diversion ring 401 and accumulates on the upper surface of the weighing plate 415. At this time, the gravity sensor 416 and the weighing plate 415 weigh the water in the hollow column 402 at regular intervals and transmit the data to the terminal so that the staff can know. The staff can judge whether the filter plate 3 is blocked or damaged by the weight of the water filtered by the filter plate 3 within a specified time.

[0036] In this embodiment, as Figure 2 and Figure 5 As shown, a drainage hole 417 is provided on the outer surface of the hollow column 402, and a shielding ring 403 is fitted on the outer surface of the hollow column 402. The shielding ring 403 is initially located at the drainage hole 417. When the shielding ring 403 slides up and down on the outer surface of the hollow column 402, it can shield or open the drainage hole 417 so that the water resources inside the hollow column 402 can be discharged.

[0037] In this embodiment, as Figure 3 As shown, a fixing plate 405 is fixedly connected to one side of the outer surface of the shielding ring 403. A sliding groove 406 is provided on the side of the fixing plate 405 away from the shielding ring 403. A lever 407 is slidably connected in the sliding groove 406. A lever plate 408 is fixedly connected to the end of the lever 407 away from the sliding groove 406. A rotating shaft 404 is fixedly connected to one side of the lever plate 408. The rotating shaft 404 is rotatably connected to the dust collection box 1.

[0038] When the rotating shaft 404 drives the lever 407 to rotate via the lever plate 408, the lever 407 can slide in the groove 406 opened on the fixed plate 405. At the same time, the fixed plate 405 is moved by the groove 406, causing the blocking ring 403 to slide up and down on the outer surface of the hollow column 402.

[0039] In this embodiment, as Figure 5 As shown, a partition 413 is fixedly connected inside the hollow column 402. A hole 414 is opened at the center of the partition 413. A baffle 412 is symmetrically attached to the lower end face of the partition 413. A sliding column 411 is fixedly connected to the opposite side of the two baffles 412. The sliding column 411 is slidably connected to the side wall of the hollow column 402. When the sliding column 411 is driven to move on the hollow column 402, it can drive the baffle 412 to move synchronously closer to or away from the lower end face of the partition 413, thus blocking or exposing the hole 414 opened on the partition 413.

[0040] In this embodiment, as Figure 3 and Figure 5As shown, a connecting block 410 is fixedly connected to the end of the sliding column 411 away from the baffle 412. An elastic linkage plate 409 is rotatably connected to the lower end face of the connecting block 410. The end of the elastic linkage plate 409 away from the connecting block 410 is rotatably connected to the upper end face of the shielding ring 403. When the shielding ring 403 descends or rises, the connecting block 410 is pulled by the elastic linkage plate 409, pushing the sliding column 411 into the hollow column 402. When the hollow column 402 can no longer slide into the hollow column 402, as the shielding ring 403 continues to descend, the shielding ring 403 will pull the elastic linkage plate 409 to extend it to adapt to the movement of the shielding ring 403.

[0041] In existing technologies, it is often difficult for staff to monitor the working status of filters in real time during operation. This not only requires staff to conduct more frequent troubleshooting and repairs, increasing maintenance and time costs and reducing overall operating efficiency, but also, when filters become clogged or damaged and are used for extended periods without timely maintenance or replacement, it affects the cleanliness of the water used in spray dust removal, thereby reducing the overall performance of the spray dust removal system. Spray dust removal systems are commonly used equipment in existing technologies and will not be specifically described in this application. Compared with existing technologies, this application can periodically weigh the water filtered by filter plate 3 and calculate the weight of the water filtered within a specified time. Operators can monitor the working status of filter plate 3 in real time, including its filtration efficiency and clogging status. This not only reduces unnecessary troubleshooting and repairs, thus lowering maintenance and time costs, but also allows for timely maintenance or replacement of clogged or damaged filter plates 3 when damage occurs. This ensures the continuous and efficient operation of the spray dust removal system, improving overall operational efficiency. Furthermore, by periodically weighing the filter plates 3, blockages or damage can be detected promptly, preventing the prolonged use of filter plates 3 that have not been maintained or replaced in a timely manner. This reduces the amount of impurities and particulate matter entering the spray dust removal system, ensuring the cleanliness of water resources and ultimately improving the overall performance of the spray dust removal system.

[0042] At other levels, this embodiment also provides a dust cleaning and collection mechanism for cleaning the surface of the filter plate 3 and intermittently driving the rotating shaft 404 to rotate, such as... Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, the dust cleaning and collection mechanism includes a protective shell 501. Support plates 502 are fixedly connected to both sides of the protective shell 501. The side of the support plates 502 away from the protective shell 501 is fixedly connected to the inner wall of the dust collection box 1. A connecting shaft 514 is rotatably connected through the bottom of the protective shell 501. A cleaning box 515 is fixedly connected to the lower end of the connecting shaft 514. A scraper 516 is fixedly connected to the lower end of the cleaning box 515. The scraper 516 is attached to the upper surface of the filter plate 3.

[0043] In this embodiment, as Figure 2 and Figure 5 As shown, a second bevel gear 513 is fixedly connected to the upper end of the connecting shaft 514. The second bevel gear 513 is meshed with a first bevel gear 512. A drive shaft 503 is fixedly connected to the first bevel gear 512. The drive shaft 503 is rotatably connected to the protective shell 501 and the dust collector 1. A drive motor 505 is fixedly connected to the side of the drive shaft 503 away from the first bevel gear 512. A support frame 504 is fixedly connected to the drive motor 505. The support frame 504 is fixedly connected to the outer wall of the dust collector 1.

[0044] When the drive shaft 503 rotates slowly, the first bevel gear 512 and the second bevel gear 513 can drive the connecting shaft 514 to rotate synchronously. At the same time, by setting the first bevel gear 512 and the second bevel gear 513 inside the protective shell 501, the first bevel gear 512 and the second bevel gear 513 can be prevented from being corroded by sewage and exhaust gas, thus avoiding the situation that affects their service life.

[0045] In this embodiment, as Figure 4 As shown, an elastic telescopic plate 509 is fixedly connected to the outer surface of the drive shaft 503 near the drive motor 505. A lever 510 is fixedly connected to the side of the elastic telescopic plate 509 away from the drive shaft 503. A lifting column 506 is provided on one side of the drive shaft 503. A support block 518 is slidably connected to the outer surface of the lifting column 506. The support block 518 is fixedly connected to the side wall of the dust collector 1. A groove 511 is provided on the outer surface of the lifting column 506 near the lever 510. The groove 511 and the lever 510 are compatible. When the drive shaft 503 drives the elastic telescopic plate 509 to rotate, the lever 510 connected to the elastic telescopic plate 509 will move synchronously with the drive shaft 503 as the center. During the movement, the lever 510 will move into the groove 511 on the outer surface of the lifting column 506. The groove 511 will push the lifting column 506 downward. At the same time, the elastic telescopic plate 509 will adaptively contract and extend according to the position of the lever 510.

[0046] In this embodiment, as Figure 7As shown, a rack plate 507 is fixedly connected to the lower end of the lifting column 506. A spring 517 is fixedly connected between the upper end face of the rack plate 507 and the lower end face of the support block 518. The spring 517 is sleeved on the outer surface of the lifting column 506. A sector gear 508 is meshed with the side of the rack plate 507 near the rotating shaft 404. The sector gear 508 is fixedly connected to the rotating shaft 404. When the lifting column 506 is subjected to force on the support block 518 and pushes the rack plate 507 downward, the rack plate 507 will drive the rotating shaft 404 to rotate synchronously through the sector gear 508, and pull the spring 517 connected between the rack plate 507 and the support block 518. When the lifting column 506 is no longer subjected to force, the rebound force of the spring 517 can pull the rack plate 507 to automatically rise and approach the support block 518, and drive the rotating shaft 404 to rotate through the sector gear 508.

[0047] Compared with existing technologies, the ability to drive the cleaning box 515 and the scraper 516 to rotate against the surface of the filter plate 3 ensures that the upper surface of the filter plate 3 is effectively cleaned. This rotating cleaning method, compared with traditional manual cleaning or fixed-position cleaning, can more comprehensively cover the surface of the filter plate 3, improve cleaning efficiency, and by automatically driving the cleaning box 515 and the scraper 516 to rotate against the surface of the filter plate 3, the frequency and intensity of manual cleaning can be reduced, thereby reducing maintenance costs and ensuring the filtration effect of the filter plate 3.

[0048] The overall working process and principles involved in the above embodiments are as follows:

[0049] During the process of workers discharging the exhaust gas from the coal-fired power plant into the dust collector box 1 through the air inlet 2 for spray dust removal, the drive motor 505 is simultaneously turned on to drive the drive shaft 503 to rotate. Since the end of the drive shaft 503 furthest from the drive motor 505 is connected to a first bevel gear 512, which meshes with a second bevel gear 513, and the second bevel gear 513 is fixedly connected to the connecting shaft 514, the rotation of the drive shaft 503, through the meshing of the first and second bevel gears 512, drives the connecting shaft 514 to rotate synchronously. This causes the cleaning box 515 connected to the lower end of the connecting shaft 514 to rotate synchronously, and... The shovel 516 connected to the lower end of the cleaning box 515 moves against the surface of the filter plate 3 to clean the surface of the filter plate 3. When dust particles accumulate due to the movement of the shovel 516, they are shoveled into the cleaning box 515 for collection, which can ensure that the upper surface of the filter plate 3 is effectively cleaned. Compared with traditional manual cleaning or fixed position cleaning, this kind of cleaning method can cover the surface of the filter plate 3 more comprehensively and improve cleaning efficiency. Moreover, by automatically driving the cleaning box 515 and the shovel 516 to rotate against the surface of the filter plate 3 for cleaning, the frequency and intensity of manual cleaning can be reduced, thereby reducing maintenance costs and ensuring the filtration effect of the filter plate 3.

[0050] Dust in the exhaust gas combines with water sprayed by the sprinkler system and falls onto the filter plate 3 below. Excess water is then filtered by the filter plate 3 and falls into the lower guide ring 401, flowing into the hollow column 402. After passing through the baffle 413 and leakage holes 414 connected within the hollow column 402, the water is collected above the weighing plate 415. As the amount of water above the weighing plate 415 increases, the gravity sensor 416 connected to the lower end of the weighing plate 415 transmits the weight of the filtered water to the terminal. Based on the weight of the filtered water collected within a specified time, staff can monitor the situation in real time. By monitoring the working status of the filter plate 3, including its filtration efficiency and clogging status, unnecessary troubleshooting and repairs can be reduced, thereby lowering maintenance and time costs. Furthermore, timely maintenance or replacement of clogged or damaged filter plates 3 ensures the continuous and efficient operation of the spray dust removal system, improving overall operational efficiency. Moreover, timely detection of clogging or damage to the filter plate 3 through periodic weighing prevents prolonged use of filter plates 3 that have not been maintained or replaced in a timely manner, thus reducing the entry of impurities and particulate matter into the spray dust removal system, ensuring water cleanliness, and ultimately improving the overall performance of the spray dust removal system.

[0051] During one revolution of the drive shaft 503, the drive shaft 503 drives the elastic telescopic plate 509 to rotate synchronously, causing the lever 510 connected to the elastic telescopic plate 509 to gradually approach the lifting column 506. When the lever 510 and the lifting column 506 come into contact, the lever 510 and the groove 511 on the outer surface of the lifting column 506 are matched, allowing the lever 510 to move exactly into the groove 511. As the lever 510 continues to rotate around the drive shaft 503, the lever 510 will push the lifting column 506 to slide vertically downward on the support block 518 through the groove 511, pushing the rack plate 507 connected to the lower end of the lifting column 506 to descend away from the support block 518, pulling the spring 517 connected between the rack plate 507 and the support block 518. During the descent of the rack plate 507, the rack plate 507 and the sector gear 508 are engaged. Furthermore, the sector gear 508 is fixedly connected to the rotating shaft 404. Therefore, the rack plate 507 will drive the rotating shaft 404 to rotate downwards synchronously through the sector gear 508, causing the lever 408 connected to the end of the rotating shaft 404 away from the sector gear 508 to move synchronously. This causes the lever 407 connected to the lever 408 to slide in the groove 406 opened on the side wall of the fixed plate 405. At this time, because the lever 408 will drive the lever 407 to rotate the shaft 404, 04 moves around the center, and the fixed plate 405 is fixedly connected to the outer wall of the shielding ring 403. The shielding ring 403 is sleeved on the outer surface of the hollow column 402. Therefore, when the lever 407 slides in the slide groove 406, it will push the fixed plate 405 to drive the shielding ring 403 to descend synchronously on the outer surface of the hollow column 402, so that the drainage hole 417 opened on the outer surface of the hollow column 402 is exposed, and the water resources weighed inside the hollow column 402 are drained.

[0052] During the descent of the blocking ring 403, the blocking ring 403 pulls one end of the elastic linkage plate 409 downwards synchronously, causing the elastic linkage plate 409 to move from an inclined state to a near-vertical state. As the state of the elastic linkage plate 409 changes, the elastic linkage plate 409 pulls the connecting block 410 closer to the hollow column 402 and pushes the sliding column 411 into the hollow column 402, causing the baffle 412 to slide on the lower end face of the partition 413, blocking the leakage hole 414 opened on the partition 413. After the two baffles 412 slide close to each other and can no longer move after blocking the leakage hole 414 opened on the partition 413, the blocking ring 403... As 03 continues to descend, the shielding ring 403 will pull the elastic linkage plate 409 to extend, opening the drain hole 417 on the outer surface of the hollow column 402, thereby allowing the water inside the hollow column 402 to flow out. This prevents the water resources subsequently filtered by the diversion ring 401 from mixing with the water resources weighed on the weighing plate 415 and being discharged together from the drain hole 417. If the subsequent water resources are mixed with the weighed water resources, it will lead to inaccurate subsequent weighing data, which cannot truly reflect the actual working state of the filter plate 3. This ensures that the water resources discharged each time are accurately weighed, providing reliable data support.

[0053] When the drive shaft 503 moves the lever 510 away from the lifting column 506 via the elastic telescopic plate 509, the spring 517 connecting the rack plate 507 and the support block 518 will pull the rack plate 507 to automatically move closer to the support block 518. This, in turn, will cause the rotating shaft 404 to reverse direction via the sector gear 508. At this time, the rotating shaft 404 will, through the lever 408, lever 407, fixing plate 405, and slide groove 406, cause the blocking ring 403 to automatically rise on the outer surface of the hollow column 402, blocking the drainage holes 417 on the outer surface of the hollow column 402. During the rising process of the blocking ring 403, the elastic linkage plate 409, connecting block 410, and slide column 416 provide additional support. 1. The baffle 412 can be pulled to slide and separate from the lower end face of the partition 413, exposing the leakage hole 414 on the partition 413. This allows the water filtered by the partition 413 to drip back onto the weighing plate 415 below for weighing. This not only automates cleaning and discharge, reducing reliance on manual operation, but also automatically discharges water from the hollow column 402 while periodically cleaning the surface of the filter plate 3. This improves work efficiency and ease of operation. Furthermore, by intermittently rotating the shaft 404, the timing of water discharge can be precisely controlled, improving the accuracy of judging the working status of the filter plate 3 by weighing the filtered water.
