At the same time, a large amount of impurities will accumulate on the lower surface of the first-level filter element 14, which will result in more impurities. The fitting processing component includes a primary filter element 14 fixedly installed inside the housing 1, and a secondary filter element 15 is fixedly connected to the top of the primary filter element 14, and a tertiary filter element 16 is fixedly connected to the upper surface of the secondary filter element 15; an inclined scraper 18 is slidably connected to the lower surface of the primary filter element 14, and a connecting block 19 is fixedly installed on one side of the inclined scraper 18; the fitting processing component also includes an extrusion electric cylinder 20, a linkage bar 21, a push shaft 22, a sleeve box 23, a linkage electric cylinder 24 and a bracket 25.

[0041] The multi-processing environmental protection desulfurization and dust removal device for power plants of the embodiment of the present invention pushes the connecting block 19 upward by the extrusion electric cylinder 20, and the connecting block 19 drives the inclined scraper 18 upward. The linkage electric cylinder 24 starts to push the push shaft 22 to move left, and the push shaft 22 moves left along the inner wall of the sleeve box 23. The linkage bar 21 causes the extrusion electric cylinder 20 to move left, and the extrusion electric cylinder 20 drives the connecting block 19 to move left. The inclined scraper 18 slides to the left along the lower surface of the primary filter element 14 to realize the scraping operation, thereby avoiding the blockage of the primary filter element 14 during long-term operation, improving the dust removal treatment effect of the desulfurization and dust removal device, and improving the stability of the device.

[0042] In some embodiments, a switching processing component is provided on one side of the cover plate 3; the switching processing component includes a rotating plate 5, a rotating motor 6, a sleeve block 7, an external pipe 8, a boost pipe 9 and an air supply pump 10; the rotating plate 5 is fixedly connected to one side of the cover plate 3, and the rotating motor 6 is fixedly installed on the upper surface of the rotating plate 5, the rotating motor 6 is used to drive the rotating plate 5 to rotate, and the sleeve block 7 is fixedly connected to one side of the rotating plate 5; the external pipe 8 is located on the inner wall of the sleeve block 7, and the boost pipe 9 is fixedly connected to one side of the outer wall of the external pipe 8, the air supply pump 10 is fixedly installed on one end of the boost pipe 9, and the air supply pump 10 is used to supply pressure to the boost pipe 9.

[0043] Specifically, the rotating plate 5 is fixedly connected to one side of the cover plate 3, and the rotating motor 6 is fixedly installed on the upper surface of the rotating plate 5, the rotating motor 6 is used to drive the rotating plate 5 to rotate, and the sleeve block 7 is fixedly connected to one side of the rotating plate 5; the outer pipe 8 is fixedly located on the inner wall of the sleeve block 7, and the boost pipe 9 is fixedly connected to one side of the outer wall of the outer pipe 8, and the air supply pump 10 is fixedly installed on one end of the boost pipe 9, and the air supply pump 10 is used to supply pressure to the boost pipe 9, or the air supply pressure can be negative pressure or positive pressure. For example, the number of air supply pumps can be two, one of the two air supply pumps is responsible for generating positive pressure, and the other is responsible for generating positive pressure, so as to adsorb impurities on the sealing gasket 2 into the outer pipe 8 and discharge them.

[0044] The multi-processing environmental protection desulfurization and dust removal device for power plants of the embodiment of the present invention adopts a switching processing component. The rotating motor 6 drives the rotating plate 5 to rotate, and the rotating plate 5 drives the cover plate 3 to rotate one hundred and eighty degrees. The cover plate 3 drives the intake pipe 4 to rotate one hundred and eighty degrees, and the rotating plate 5 simultaneously drives the sleeve block 7 to rotate one hundred and eighty degrees, and the external exhaust pipe 8 drives the boost pipe 9 to rotate one hundred and eighty degrees. The sleeve block 7 can be rotated to the extrusion position of the lower surface of the sealing gasket 2, and the air supply pump 10 pressurizes the external air into the inside of the boost pipe 9, and the boost pipe 9 is poured into the inside of the external exhaust pipe 8. The impurities in the external exhaust pipe 8 are forced to be discharged through the pressurization, and can be quickly and automatically removed according to the accumulation thickness, thereby greatly improving the dust removal treatment effect of the desulfurization and dust removal device.

[0045] In some embodiments, the upper surface of the sleeve 7 is at the same level as the upper surface of the cover plate 3, and the material of the sealing gasket 2 is a high molecular polymer, so that after rotation, the sleeve 7 can rotate to the squeezing position of the lower surface of the sealing gasket 2 to facilitate the discharge of impurities.

[0046] Furthermore, the air supply pump 10 is fixedly connected to the sleeve block 7, and the vertical cross-section of the outer discharge pipe 8 is L-shaped, so that impurities flow into the outer discharge pipe 8 under the action of gravity, and the upper end of the outer discharge pipe 8 absorbs the impurities, and the air supply pump 10 is connected to the bottom of the outer discharge pipe 8, so that the air supply pump can act to absorb and discharge impurities.

[0047] Furthermore, a support block 11 is provided at the top of the rotating motor 6, and the housing 1 and the rotating motor 6 are fixedly connected to the support block 11, and the vertical cross-section of the support block 11 is T-shaped.

[0048] In some embodiments, a flange 12 is fixedly connected to the outer wall of the outer exhaust pipe 8 and away from the boost pipe 9, and the vertical cross-section of the flange 12 is annular.

[0049] In some embodiments, the top of the shell 1 is fixedly connected with an exhaust pipe 13, and the exhaust pipe 13 is connected to the shell 1. The top of the shell 1 is fixedly connected with an exhaust pipe 13, and the exhaust pipe 13 is connected to the shell 1, so that the filtered flue gas can be discharged upward along the exhaust pipe 13, and the air after desulfurization and dust removal can be discharged upward.

[0050] In some embodiments, the vertical cross-section of the inclined scraper strip 18 is triangular, and the inclined scraper strip 18 is made of resin material.

[0051] Specifically, the triangle has a robust geometric property, and its sharp or blunt edge appearance can be tailored to the application requirements to achieve effective scraping, cleaning or guiding functions.

[0052] At the same time, the inclined scraper strip 18 is made of resin material, and this material selection brings many benefits. Resin is a lightweight, high-strength and corrosion-resistant material. It has good wear resistance and anti-aging properties, which can ensure that the scraper strip maintains stable performance during long-term use. In addition, the resin material also has good processing properties and can be easily made into various shapes and sizes to meet the needs of different application scenarios.

[0053] In the application of the inclined scraper bar 18, its triangular vertical cross-sectional shape and resin material work together. The triangular edge can effectively scrape away dirt, residue or liquid attached to the surface, while the resin material ensures that the scraper bar will not fail due to wear or corrosion during use. This design makes the inclined scraper bar 18 perform well in various cleaning, scraping or guiding tasks, especially in situations where high precision and durability are required.

[0054] In some embodiments, the multi-processing power plant environmental protection desulfurization and dust removal device further includes a detection component, the detection component includes a rubber sleeve 26 slidably mounted on the inner wall of the shell 1 and close to its corner line, and a controller 17 fixedly connected to the shell 1 is provided on one side of the rubber sleeve 26;

[0055] A slide bar 27 is bonded and fixed to the outer wall of the rubber sleeve 26, and the slide bar 27 is slidably connected to the housing 1. A linkage block 28 is fixedly connected to one end of the slide bar 27, and a threaded sleeve block 29 is fixedly connected to the bottom end of the linkage block 28. A guide frame 30 is slidably connected to the outer wall of the threaded sleeve block 29.

[0056] A driving motor 31 is fixedly mounted on one end of the guide frame 30, a screw rod 32 is threadedly connected to the inner wall of the threaded sleeve block 29, and the driving motor 31 is used to drive the screw rod 32 to rotate;

[0057] The other end of the slide bar 27 is fixedly connected with a thickness sensor 33 .

[0058] Specifically, the screw 32 is driven to rotate forward by the driving motor 31, and the screw 32 drives the threaded sleeve 29 to move right under the action of the thread, and the threaded sleeve 29 moves right along the inner wall of the guide frame 30, and the threaded sleeve 29 causes the linkage block 28 to move right, and the linkage block 28 drives the slide bar 27 to move right, and the slide bar 27 causes the rubber sleeve 26 to move right, so that the rubber sleeve 26 and the slide bar 27 can be guided to move right along the corner position of the inner wall of the shell 1. At the same time, the slide bar 27 drives the thickness sensor 33 to move right, and the thickness sensor 33 can detect the thickness of smoke and dust impurities along the lower surface of the primary filter element 14. When the dust impurities at the bottom of the primary filter element 14 are too much, the thickness sensor 33 is used for sensing. When the thickness value sensed by the thickness sensor 33 exceeds the thickness value set by the controller 17, the rotating motor 6 is started by the controller 17, and the controller 17 simultaneously starts the driving motor 31 to drive the screw 32 to reverse.

[0059] In some embodiments, the outer wall of the threaded sleeve 29 is slidably connected to the inner wall of the guide frame 30, and both the outer wall of the threaded sleeve 29 and the inner wall of the guide frame 30 are smooth surfaces to reduce friction during operation.

[0060] Technical effects and advantages of the present invention:

[0061] 1. The present invention adopts a switching processing mechanism. The rotating motor 6 drives the rotating plate 5 to rotate. The rotating plate 5 drives the cover plate 3 to rotate 180 degrees. The cover plate 3 drives the intake pipe 4 to rotate 180 degrees, and the rotating plate 5 drives the sleeve block 7 to rotate 180 degrees at the same time. The outer pipe 8 drives the boost pipe 9 to rotate 180 degrees. The sleeve block 7 can be rotated to the extrusion position of the lower surface of the sealing gasket 2. The air supply pump 10 pressurizes the external air into the inside of the boost pipe 9, and the boost pipe 9 is poured into the inside of the outer pipe 8. The impurities in the outer pipe 8 are forced to be discharged through the pressurization, and can be quickly and automatically removed according to the accumulation thickness, thereby greatly improving the dust removal processing effect of the desulfurization and dust removal device.

[0062] 2. The present invention adopts a detection component, which pushes the connecting block 19 upward through the extrusion electric cylinder 20, and the connecting block 19 drives the inclined scraper 18 upward. The linkage electric cylinder 24 starts to push the push shaft 22 to move left, and the push shaft 22 moves left along the inner wall of the sleeve box 23. The linkage bar 21 makes the extrusion electric cylinder 20 move left, and the extrusion electric cylinder 20 drives the connecting block 19 to move left. The inclined scraper 18 slides left along the lower surface of the primary filter element 14 to achieve the scraping operation, and enters the sleeve block 7 from the sealing gasket 2, and drives the external discharge pipe 8 through the sleeve block 7 to divert impurities, so that automatic removal can be quickly achieved according to the accumulation thickness.

[0063] 3. The present invention adopts a fitting processing mechanism, which drives the screw 32 to rotate forward by driving the motor 31. The screw 32 drives the threaded sleeve 29 to move right under the action of the thread. The threaded sleeve 29 causes the linkage block 28 to move right, and the linkage block 28 drives the slide bar 27 to move right. The rubber sleeve 26 and the slide bar 27 can be guided to move right along the corner position of the inner wall of the shell 1. The thickness sensor 33 can detect the thickness of smoke and dust impurities along the lower surface of the primary filter element 14. When the thickness value sensed by the thickness sensor 33 exceeds the thickness value set by the controller 17, the rotating motor 6 is started by the controller 17, so that the dust and impurities on the lower surface of the primary filter element 14 can be accurately detected, and rapid processing can be achieved after the thickness is detected, thereby avoiding excessive dust and impurities on the lower surface of the primary filter element 14, and rapid automatic removal can be achieved according to the accumulated thickness.

[0064] The interaction of the above multiple functions firstly realizes accurate thickness detection of dust impurities on the lower surface of the primary filter element 14, while the rotating plate 5 drives the sleeve block 7 to rotate 180 degrees, the outer pipe 8 drives the boost pipe 9 to rotate 180 degrees, and finally the inclined scraper 18 slides leftward along the lower surface of the primary filter element 14 to realize the scraping operation. In summary, according to the accumulation thickness on the lower surface of the primary filter element 14, automatic removal can be realized quickly, greatly improving the dust removal effect of the desulfurization and dust removal device.

The vertical cross-section of the inclined scraper strip 18 is triangular, and the inclined scraper strip 18 is made of resin material.

[0071] In this embodiment, as shown in the attached Figure 6 As shown, the detection assembly includes a rubber sleeve 26 slidably mounted on the inner wall of the housing 1 and near the corner line thereof, and a controller 17 fixedly connected to the housing 1 is provided on one side of the rubber sleeve 26; a slide bar 27 is bonded and fixed to the outer wall of the rubber sleeve 26, and the slide bar 27 is slidably connected to the housing 1, one end of the slide bar 27 is fixedly connected to a linkage block 28, a threaded sleeve block 29 is fixedly connected to the bottom end of the linkage block 28, and a guide frame 30 is slidably connected to the outer wall of the threaded sleeve block 29;

[0072] A driving motor 31 is fixedly mounted on one end of the guide frame 30, a screw 32 is threadedly connected to the inner wall of the threaded sleeve 29, and the driving motor 31 is used to drive the screw 32 to rotate; a thickness sensor 33 is fixedly connected to the other end of the slide bar 27. The outer wall of the threaded sleeve 29 is slidably connected to the inner wall of the guide frame 30, and both the outer wall of the threaded sleeve 29 and the inner wall of the guide frame 30 are smooth surfaces.

[0073] The working principle of the multi-processing environmental protection desulfurization and dust removal device for power plants of the present invention is as follows:

[0074] First, when the present invention performs desulfurization and dust removal, the desulfurized high-temperature smoke air is connected to the air intake pipe 4, enters the inside of the cover plate 3 through the air intake pipe 4, enters the sealing gasket 2 along the cover plate 3, enters the inside of the housing 1 through the sealing gasket 2, and enters the first-level filter element 14 through the housing 1, so that the first-level filter element 14 performs first-level filtration of impurities, and at the same time passes through the second-level filter element 15 for second-level filtration, and the third-level filter element 16 performs third-level filtration, and the filtered smoke is discharged upward along the exhaust pipe 13. At the same time, a large amount of impurities will accumulate on the lower surface of the first-level filter element 14, which will result in more impurities.

[0075] Secondly, when the present invention is detecting, the screw 32 is driven to rotate forward by the driving motor 31, and the screw 32 drives the threaded sleeve 29 to move right under the action of the thread, and at the same time, the threaded sleeve 29 moves right along the inner wall of the guide frame 30, and the threaded sleeve 29 makes the linkage block 28 move right, and the linkage block 28 drives the slide bar 27 to move right, and the slide bar 27 makes the rubber sleeve 26 move right, so that the rubber sleeve 26 and the slide bar 27 can be guided to move right along the corner position of the inner wall of the shell 1. At the same time, the slide bar 27 drives the thickness sensor 33 to move right, and the thickness sensor 33 can detect the thickness of smoke and dust impurities along the lower surface of the primary filter element 14. When the dust impurities at the bottom of the primary filter element 14 are too much, the thickness sensor 33 is used for sensing. When the thickness value sensed by the thickness sensor 33 exceeds the thickness value set by the controller 17, the rotating motor 6 is started by the controller 17, and the controller 17 simultaneously starts the driving motor 31 to drive the screw 32 to reverse.

[0076] At the same time, the screw rod 32 drives the screw rod 32 to reverse, the screw rod 32 drives the threaded sleeve block 29 to move left, the threaded sleeve block 29 makes the linkage block 28 move left, the linkage block 28 drives the slide bar 27 to make the rubber sleeve 26 move left, the slide bar 27 makes the thickness sensor 33 move left, so that the thickness sensor 33 can return to its original position.

[0077] Then, when the present invention performs switching processing, the rotating motor 6 is started through the controller 17, and the shell 1 supports the support block 11, and the support block 11 supports the rotating motor 6, so that the rotating motor 6 drives the rotating plate 5 to rotate, and the rotating plate 5 drives the cover plate 3 to rotate one hundred and eighty degrees, and at the same time the cover plate 3 drives the intake pipe 4 to rotate one hundred and eighty degrees, and the rotating plate 5 drives the sleeve block 7 to rotate one hundred and eighty degrees, the sleeve block 7 makes the outer pipe 8 rotate one hundred and eighty degrees, the outer pipe 8 drives the boost pipe 9 to rotate one hundred and eighty degrees, and the boost pipe 9 makes the air supply pump 10 rotate one hundred and eighty degrees, so that the sleeve block 7 can be rotated to the extrusion position of the lower surface of the sealing gasket 2.

[0078] Finally, when the present invention is subjected to the laminating treatment, the connecting block 19 is pushed upward by the extrusion electric cylinder 20, and the connecting block 19 drives the inclined scraper 18 upward, and the inclined scraper 18 moves upward to fit the lower surface of the primary filter element 14. At the same time, the bracket 25 supports the linkage electric cylinder 24, and the linkage electric cylinder 24 starts to push the push shaft 22 to move left, and the push shaft 22 moves left along the inner wall of the sleeve box 23, and the push shaft 22 drives the linkage bar 21 to move left, and the linkage bar 21 makes the extrusion electric cylinder 20 move left, and the extrusion electric cylinder 20 drives the connecting block 19 to move left. At the same time, the connecting block 19 makes the inclined scraper 18 move left, and the inclined scraper 18 slides left along the lower surface of the primary filter element 14 to achieve the scraping operation, and the impurities on the lower surface of the primary filter element 14 can be cleaned up. In this way, the impurities at the bottom of the primary filter element 14 will enter the inside of the sealing gasket 2 along the housing 1, and enter the inside of the sleeve block 7 from the sealing gasket 2, and drive the outer discharge pipe 8 to divert the impurities through the inside of the sleeve block 7.

[0079] At the same time, the air supply pump 10 is started, and the air supply pump 10 pressurizes the external air and enters the inside of the boosting pipe 9, and then pours it into the inside of the external exhaust pipe 8 through the boosting pipe 9. The impurities in the external exhaust pipe 8 are forced to be discharged through the pressurization.
