[0002] In a thermal power plant, the role of a flue gas dust removal device is crucial. It is mainly used to remove solid particles in the flue gas generated during the combustion process to reduce environmental pollution. With the increase in the flue gas volume and particulate emissions during thermal power generation, the design and cleaning and maintenance of the flue gas dust removal device become particularly important. In order to ensure the dust removal efficiency, extend the service life of the equipment and reduce the downtime, the design that is convenient for cleaning the inner wall has become a trend.

[0003] The patent with the publication number CN212141798U discloses a flue gas dust removal device. The flue gas dust removal device includes: a bin body having an inner cavity filled with dust removal particles, and the bin body also has an air inlet part and an air outlet part communicating with the inner cavity; a vibration filtering mechanism, the input end of which is communicated with the bottom of the bin body to receive and clean the dust removal particles; a lifting mechanism, the input end of which is communicated with the output end of the vibration filtering mechanism, and the output end of which is communicated with the top of the bin body to fill the dust removal particles cleaned by the vibration filtering mechanism into the bin body; and a valve provided at the connection between the bin body and the vibration filtering mechanism. This patent can be applied to the flue gas dust removal of small coal-fired heating boilers and can operate stably for a long period.

[0004] However, during the use of the above device, it is difficult to comprehensively filter the particulate matter and dust in the flue gas, resulting in a slow dust removal speed of the flue gas and affecting the efficiency of subsequent flue gas dust removal. Therefore, a flue gas dust removal device for thermal power generation that is convenient for cleaning the inner wall is proposed to solve the above-mentioned problems. Summary of the Invention

Specific embodiments

[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0015] Please refer to Figures 1 - 9, an embodiment of the present invention is: a flue gas dust removal device for thermal power generation that is convenient for cleaning the inner wall, including a base 1. A bracket 2 is fixedly connected to the top of the base 1. An inner wall of the bracket 2 is fixedly connected to a tank body 3. A motor 4 is fixedly connected to the top of the tank body 3. A smoke inlet valve 5 is fixedly connected to the bottom of the tank body 3. An output end of the motor 4 is fixedly connected to a reciprocating lead screw 8. An inner filter column 9 is fixedly connected to an inner wall of the tank body 3. When the device is started, an operator needs to connect an external exhaust pipe to the smoke inlet valve 5. At this time, the thick smoke that needs to be dust-removed will enter the inside of the inner filter column 9 through the smoke inlet valve 5. At this time, the inner filter column 9 can intercept large particulate matters in the flue gas. The inner filter column 9 can intercept larger particles in the flue gas, reduce blockage and wear of the equipment, and improve the efficiency of flue gas dust removal. A rotating block 10 is fixedly connected to a circumferential surface of the reciprocating lead screw 8. A connecting rod 11 is fixedly connected to a circumferential surface of the rotating block 10. A long column 12 is fixedly connected to an inner wall of the connecting rod 11. A filter plate 13 is fixedly connected to a circumferential surface of the long column 12. At the same time, after the flue gas enters the inside of the inner filter column 9, the motor 4 will be started at this time. The output end of the motor 4 will drive the reciprocating lead screw 8 to rotate. The rotation of the reciprocating lead screw 8 will drive the rotating block 10 to rotate. The rotation of the rotating block 10 will drive the connecting rod 11 to rotate. The rotation of the connecting rod 11 will drive the long column 12 to rotate. The long column 12 will drive the filter plate 13 to rotate. During the rotation of the filter plate 13, it can capture and filter smaller particulate matters in the flue gas inside the tank body 3, so that the dust particulate matters stay on the surface of the filter plate 13, improving the effect of flue gas dust removal of the device and the dust removal speed of the device. A limiting column 14 is fixedly connected to an inner wall of the tank body 3. A cross plate 15 is movably connected to a circumferential surface of the reciprocating lead screw 8. A fixing column 16 is fixedly connected to an inner wall of the cross plate 15. An inner plate 17 is fixedly connected to a circumferential surface of the fixing column 16. A storage tank 18 is fixedly connected to the top of the base 1. A connecting pipe 19 is fixedly communicated with the storage tank 18. A cleaning mechanism 6 for cleaning the inner wall dust is arranged on an inner wall of the tank body 3. A pushing mechanism 7 for pushing and collecting dust and sundries is arranged on the inner wall of the tank body 3. The cross plate 15 is slidably connected to a circumferential surface of the limiting column 14. The inner plate 17 contacts the inner filter column 9. The reciprocating lead screw 8 contacts the tank body 3. The connecting pipe 19 is communicated with the tank body 3. While the reciprocating lead screw 8 rotates, the reciprocating lead screw 8 will drive the cross plate 15 to rotate. However, the cross plate 15 is limited by the limiting column 14. At this time, the cross plate 15 can only move up and down reciprocally through a reciprocating groove on the surface of the reciprocating lead screw 8. The movement of the cross plate 15 will drive the fixing column 16 to move. The movement of the fixing column 16 will drive the inner plate 17 to move. The movement of the inner plate 17 can clean the inner wall of the inner filter column 9 and scrape off dust, avoiding blockage of the filter holes of the inner filter column 9 and affecting the subsequent dust removal effect, and improving the service life of the device.

[0016] The cleaning mechanism 6 includes a roller 601, a reciprocating lead screw two 602, a limit post two 603, a moving groove block 604, and a scraper 605. The roller 601 is rotatably connected to the inner wall of the connecting rod 11. The reciprocating lead screw two 602 is fixedly connected to the inner wall of the roller 601. The limit post two 603 is fixedly connected to the bottom of the connecting rod 11. The moving groove block 604 is movably connected to the circumferential surface of the reciprocating lead screw two 602. The scraper 605 is fixedly connected to the top of the moving groove block 604. When the device is started, the rotational movement of the reciprocating lead screw one 8 will drive the rotational movement of the connecting rod 11. The movement of the connecting rod 11 will drive the movement of the roller 601. During the movement of the roller 601, the roller 601 will generate frictional force due to contact with the tank body 3, resulting in the rotation of the roller 601. The rotation of the roller 601 will drive the rotation of the reciprocating lead screw two 602. The rotation of the reciprocating lead screw two 602 will drive the rotation of the moving groove block 604. However, at this time, the moving groove block 604 is limited by the limit post two 603, causing the moving groove block 604 to only move reciprocally up and down through the reciprocating groove on the surface of the reciprocating lead screw two 602. The reciprocating up and down movement of the moving groove block 604 will drive the movement of the scraper 605. The movement of the scraper 605 can clean and scrape the dust on the surface of the filter plate 13, avoiding excessive dust and particulate matter from clogging the openings on the surface of the filter plate 13, affecting the subsequent use effect, and improving the use ability of the device. The cleaning mechanism 6 further includes a connecting ring 606, a first elastic telescopic rod 607, a double inclined block 608, and a resisting block 609. The connecting ring 606 is fixedly connected to the inner wall of the moving groove block 604. The first elastic telescopic rod 607 is fixedly connected to the inner wall of the connecting ring 606. The double inclined block 608 is fixedly connected to the telescopic end of the first elastic telescopic rod 607. The resisting block 609 is fixedly connected to the circumferential surface of the inner filter column 9. The roller 601 contacts the tank body 3. The moving groove block 604 is slidably connected to the circumferential surface of the limit post two 603. The scraper 605 contacts the filter plate 13. At the same time, during the up and down movement of the moving groove block 604, the up and down movement of the moving groove block 604 will drive the movement of the connecting ring 606. The movement of the connecting ring 606 will drive the movement of the first elastic telescopic rod 607. The movement of the first elastic telescopic rod 607 will drive the movement of the double inclined block 608. After the double inclined block 608 moves a certain distance, the double inclined block 608 will contact the resisting block 609 and receive the anti-extrusion driving force of the resisting block 609. At this time, the double inclined block 608 will move away from the surface of the inner filter column 9. When the double inclined block 608 no longer contacts the resisting block 609, the double inclined block 608 will perform a certain knocking vibration on the surface of the inner filter column 9, which can improve the service life of the inner filter column 9 and avoid excessive particulate matter on the surface of the inner filter column 9 after long-term use, affecting the subsequent flue gas inlet and outlet speeds.

[0017] Working principle: When the device is started, the operator needs to connect the external smoke exhaust pipe to the smoke inlet valve 5. At this time, the thick smoke that needs to be dust-removed will enter the inside of the inner filter column 9 through the smoke inlet valve 5. At this time, the inner filter column 9 can intercept large particles in the smoke. The inner filter column 9 can intercept larger particles in the smoke, reduce the blockage and wear of the equipment, and improve the efficiency of flue gas dust removal. At the same time, after the flue gas enters the inside of the inner filter column 9, the motor 4 will be started at this time. The output end of the motor 4 will drive the reciprocating lead screw 8 to rotate. The rotation of the reciprocating lead screw 8 will drive the rotating block 10 to rotate. The rotation of the rotating block 10 will drive the connecting rod 11 to rotate. The rotation of the connecting rod 11 will drive the long column 12 to rotate. The long column 12 will drive the filter plate 13 to rotate. During the rotation of the filter plate 13, it can capture and filter smaller particles in the flue gas inside the tank body 3, so that the dust particles stay on the surface of the filter plate 13, improve the flue gas dust removal effect of the device, and improve the dust removal speed of the device. While the reciprocating lead screw 8 is rotating, the reciprocating lead screw 8 will drive the cross plate 15 to rotate. However, the cross plate 15 is limited by the limit post 14. At this time, the cross plate 15 can only move up and down reciprocally through the reciprocating groove on the surface of the reciprocating lead screw 8. The movement of the cross plate 15 will drive the fixed post 16 to move. The movement of the fixed post 16 will drive the inner plate 17 to move. The movement of the inner plate 17 can clean the inner wall of the inner filter column 9 and scrape off the dust, which can prevent the filter holes of the inner filter column 9 from being blocked, affect the subsequent dust removal effect, and extend the service life of the device.

[0018] When the device is started, the rotational movement of the reciprocating lead screw 1-8 will drive the connecting rod 11 to rotate and move. The movement of the connecting rod 11 will drive the roller 601 to move. During the movement of the roller 601, due to the contact with the tank body 3, a frictional force will be generated, causing the roller 601 to rotate. The rotation of the roller 601 will drive the reciprocating lead screw 2-602 to rotate. The rotation of the reciprocating lead screw 2-602 will drive the moving groove block 604 to rotate. However, at this time, the moving groove block 604 is limited by the limiting post 2-603, resulting in the moving groove block 604 can only move up and down reciprocally through the reciprocating groove on the surface of the reciprocating lead screw 2-602. The reciprocating up and down movement of the moving groove block 604 will drive the scraper 605 to move. The movement of the scraper 605 can clean and scrape the dust on the surface of the filter plate 13, avoiding excessive dust and particulate matter from blocking the openings on the surface of the filter plate 13, affecting the subsequent use effect, and improving the serviceability of the device. At the same time, during the up and down movement of the moving groove block 604, the up and down movement of the moving groove block 604 will drive the connecting ring 606 to move. The movement of the connecting ring 606 will drive the elastic telescopic rod 1-607 to move. The movement of the elastic telescopic rod 1-607 will drive the double inclined block 608 to move. After the double inclined block 608 moves a certain distance, the double inclined block 608 will contact the abutting block 609 and receive the anti-extrusion driving force of the abutting block 609. At this time, the double inclined block 608 will move away from the surface of the inner filter column 9. When the double inclined block 608 no longer contacts the abutting block 609, the double inclined block 608 will perform a certain knocking vibration on the surface of the inner filter column 9, which can improve the service life of the inner filter column 9 and avoid excessive particulate matter on the surface of the inner filter column 9 after long-term use, affecting the subsequent flue gas inlet and outlet speeds.

When the device is in use, the rotational movement of the moving groove block 604 will drive the second fixing column 701 to rotate and move. The movement of the second fixing column 701 will drive the annular plate 702 to move. During the movement of the annular plate 702, the transverse plate 703 will be driven to move. During the up-and-down rotational movement of the annular plate 702 and the transverse plate 703, the annular plate 702 and the transverse plate 703 can clean and scrape the dust particles on the inner wall of the tank body 3 in all directions, improving the service life of the device, reducing the difficulty and cost of manual cleaning, and ensuring the normal operation of the device during use.

At the same time, during the movement of the moving groove block 604, the movement of the moving groove block 604 will drive the pressure rod 704 to move. After the pressure rod 704 moves a certain distance, the pressure rod 704 will contact and squeeze the connecting round block 706 to push the connecting round block 706. At this time, after the connecting round block 706 receives the extrusion driving force, the connecting round block 706 will compress the second elastic telescopic rod 705. The telescopic movement of the second elastic telescopic rod 705 will drive the connecting round block 706 to move. The movement of the connecting round block 706 will drive the third elastic telescopic rod 707 to move. The movement of the third elastic telescopic rod 707 will drive the pushing inclined plate 708 to move. At this time, the pushing inclined plate 708 will always be in contact with the inner wall of the tank body 3 through the reset characteristic of the third elastic telescopic rod 707. During the movement of the pushing inclined plate 708, it can push a certain amount of dust and particles to move, which can improve the subsequent collection efficiency and reduce the subsequent cleaning difficulty.

[0020] Working principle: When the device is in use, the rotational movement of the moving groove block 604 will drive the rotation and movement of the second fixed column 701. The movement of the second fixed column 701 will drive the movement of the annular plate 702. During the movement of the annular plate 702, it will drive the movement of the cross plate 703.
