Description

Technical Field

[0001] This invention relates to the field of particulate matter purification technology in industrial kilns, and more particularly to a purification device and method for treating particulate matter in industrial kilns. Background Technology

[0002] Industrial kilns are high-energy-consuming and high-emission equipment in national production. During combustion or smelting, they generate a large amount of high-temperature and high-dust industrial flue gas. The particulate matter (dust) contained in this flue gas is one of the main air pollutants. If it is discharged directly without effective purification treatment, it will cause serious pollution to the atmospheric environment and endanger human health.

[0003] Existing dust removal methods require offline (i.e., shutting down the corresponding filter unit) dust removal, which leads to a sudden reduction in the overall filtration area and increased system resistance fluctuations, potentially affecting the stable operation of the kiln. This is especially true when dealing with continuously emitted kiln flue gas, making it difficult to achieve true non-stop maintenance and repair. In particular, how to efficiently and uniformly clean the filter media automatically without interrupting the purification process, achieve simultaneous cleaning of ash and slag, and flexibly adjust the processing load of each module remains a challenge that needs to be optimized and overcome in existing technologies.

[0004] Therefore, there is an urgent need to develop an industrial kiln flue gas purification device that is more integrated, more automated, and capable of continuous operation and online cleaning, in order to meet the increasingly stringent environmental standards and the industrial production requirements for continuous and stable operation. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a purification device and method for treating particulate matter in industrial kilns.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A purification device for treating particulate matter in industrial kilns includes a support member. At least two purification components are mounted on the top of the support member. Each purification component includes a housing and a partition plate fixed to one end. A sliding plate is movably connected between the top and bottom of the housing. A filter plate mechanism is mounted on the side of the sliding plate. A second flue is fixed to the side of the sliding plate via a connecting block. A flue hole is opened on the side of the second flue. A first flue is fixed between frames fixed to the outer walls of the top of the two housings. A connecting seat is welded to the side of the first flue. The two connecting seats are connected by an input pipe. The same output pipe is installed at the bottom of the two housings.

[0007] As a further embodiment of the present invention: the filter plate mechanism includes a filter screen and a flexible strip, the flexible strip being adhered to the side wall of the sliding plate, and the filter screen being adhered to the side of the flexible strip.

[0008] As a further embodiment of the present invention: the vibration mechanism installed between the two sides of the housing includes a rotating shaft, a mounting ring, a rubber head, and a hammer rod. The rotating shaft is movably connected to the inner wall of the through holes opened on both sides of the housing. The mounting ring is welded to the outer circumference of the rotating shaft. The hammer rod is welded to the bottom of the mounting ring. The rubber head is fixed to the end of the hammer rod by embedding.

[0009] As a further embodiment of the present invention: the vibration mechanism further includes a limiting cover and a coil spring, the limiting cover being fixed to the end of the rotating shaft, and the coil spring being sleeved on the outer circumferential wall of the rotating shaft with both ends of the coil spring being fixed between the housing and the limiting cover respectively.

[0010] As a further embodiment of the present invention: an extension rod is fixed to one side of the outer wall of the sliding plate, a conductive component is fixed to one end of the extension rod, a vertical plate is fixed to the top outer wall of the housing, and multiple sets of conductive track components that cooperate with the conductive component are fixed to the side of the vertical plate.

[0011] As a further embodiment of the present invention: a connecting plate is fixed to one side of the outer wall of the housing, an electromagnet is fixed to the bottom of the connecting plate, a driving plate is fixed to one end of the rotating shaft, and a permanent magnet is fixed to the top of the driving plate.

[0012] As a further embodiment of the present invention: a connecting plate is fixed to the inner surface of the sliding plate, and an inclined plate is fixed to the end of the connecting plate away from the sliding plate.

[0013] As a further embodiment of the present invention: the support member includes a first mounting plate and a second mounting plate. The first mounting plate and the second mounting plate are welded and fixed together by a series of support rods. The output end of the electric telescopic rod fixed to the bottom outer wall of the first mounting plate is fixed with a U-shaped plate. The rotating rod movably connected between the two sides of the U-shaped plate is driven by a self-locking motor. The outer circumference of the rotating rod is fixed with a sliding plate. Both ends of the sliding plate are movably connected with sliding sleeves, and the sliding sleeves and the bottom of the sliding plate are movably connected by a rotating shaft.

[0014] As a further embodiment of the present invention: a controller is mounted on the side of the housing.

[0015] A purification method for treating particulate matter in industrial kilns includes the following steps: S1: The flue gas is diverted to two connecting seats through the input pipe and enters flue one. The drive sliding plate drives flue two to move up and down in flue one, adjusting the opening and closing of its side flue holes and corresponding connecting seats. The flue gas enters flue two through the aligned flue holes and is introduced into the inner cavity of the shell. S2: Flue gas passes through the filter screen inside the housing and is filtered, while the clean flue gas is discharged from the output pipe. S3: The controller controls the self-locking motor or electric telescopic rod to drive the sliding plate to move longitudinally. When the sliding plate moves, it drives the conductive component to slide along the conductive track on the upright plate. When the conductive component contacts the conductive track, the circuit is turned on, the electromagnet is energized and attracts the permanent magnet, which drives the rotating shaft to rotate and causes the coil spring to store energy. When the conductive component slides to the gap of the conductive track, the power is cut off, the electromagnet loses magnetism, and the coil spring drives the rotating shaft to rotate back, causing the rubber head at the end of the hammer rod to strike the filter screen. The flexible connection of the filter screen generates vibration to shake off surface particles. S4: As the sliding plate moves downward, the dislodged particles are guided by the inclined plate on its side and slide out through the opening at the bottom of the housing, achieving cleaning without stopping the machine.

[0016] Compared with the prior art, the present invention provides a purification device and method for treating particulate matter in industrial kilns, which has the following beneficial effects: The two sets of parallel purification components in this application are separated by a partition. When one set is shut down due to maintenance, inspection or cleaning, its flue can be moved to make its flue hole misalign with the connecting seat, cutting off the entry of flue gas. The other set of purification components can continue to operate at full load or with adjusted load without being affected, ensuring the continuity and stability of the flue gas purification process of industrial kilns and avoiding production interruption.

[0017] The movement of the sliding plate triggers the periodic switching of the conductive components and the conductive track, automatically controlling the electromagnet to switch on and off. This drives the rubber head to perform high-frequency, reciprocating tapping on the filter screen under the action of the coil spring. Without additional machine shutdown or manual intervention, it can effectively shake off the particles accumulated on the surface of the filter screen, maintain the air circulation efficiency of the filter screen, and extend its service life.

[0018] The continuous up-and-down movement of the sliding plate during the dust removal process, combined with the periodic tapping of the vibration mechanism, causes the position of the rubber head hitting the filter screen to change longitudinally each time. This achieves segmented and uniform cleaning of the entire working surface of the filter screen, avoiding over-cleaning of local areas or cleaning dead corners, and ensuring the comprehensiveness and effectiveness of dust removal.

[0019] The dust removal and slag discharge processes are completed in conjunction with the same self-locking motor and electric telescopic rod. When the sliding plate moves the filter screen for cleaning or adjustment, the inclined plate fixed to its side moves synchronously. In the purification state, the inclined plate seals the bottom of the shell; in the slag discharge state, the sliding plate moves down to form a gap between the inclined plate and the bottom of the shell, and the shaken particles can slide out automatically along the inclined plate.

[0020] By driving flue 2 to move up and down within flue 1, the relative opening between its side flue holes and the fixed connecting seat can be precisely adjusted. This allows operators to flexibly adjust the flue gas flow rate entering each purification component according to the actual flue gas treatment volume, particulate matter concentration, or changes in system resistance. When operating a single unit, the opening can be adjusted to ensure treatment capacity; when operating two units, the load can be distributed.

Detailed Implementation

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0034] A purification device for treating particulate matter in industrial kilns, such as Figures 1 to 9 As shown, the system includes a support member, on the top of which are two sets of purification components. Each purification component includes a housing 1 and a partition 14 fixed to one end by screws. A sliding plate 7 is slidably connected between the top and bottom of the housing 1. A filter plate mechanism is installed on the side of the sliding plate 7. The filter plate mechanism includes a filter screen 20 and a flexible strip 34. The flexible strip 34 is adhered to the side wall of the sliding plate 7, and the filter screen 20 is adhered to the side of the flexible strip 34. A second flue 27 is fixed to the side of the sliding plate 7 by a connecting block 17. A smoke hole 31 is opened on the side of the second flue 27 near the top. A frame 21 is fixed to the top outer wall of the two housings 1 by screws. A first flue 8 is fixed between the two frames 21 by screws. A connecting seat 30 is welded to the side of the first flue 8. The two connecting seats 30 are connected to each other by an input pipe 9. The same output pipe 13 is installed at the bottom of the two housings 1.

[0035] When flue gas purification is required, the inlet pipe 9 is first connected to the flue of the industrial kiln. The flue gas is introduced into the two connecting seats 30 by the diversion effect of the inlet pipe 9. In the initial state, the smoke holes 31 on the two flue 27 are misaligned with their corresponding connecting seats 30. At this time, the flue gas cannot enter the flue 27 through the connecting seats 30. When purification begins, the flue 27 is driven to move up or down along the inner surface of the flue 8. When the smoke holes 31 on the side of the flue 27 and the connecting seats 30 are relatively open, the flue gas is input into the interior of the flue 27 through the connecting seats 30 and the smoke holes 31. Finally, the flue gas enters the interior of the shell 1 through the flue 27. In actual operation, flexible materials such as rubber are wrapped around the outer wall of the flue 27 to improve the fit between it and the inner surface of the flue 8.

[0036] After the flue gas enters the housing 1, it is filtered by the filter screen 20. The filtered flue gas then enters the inner cavity between the side wall of the housing 1 and the sliding plate 7 through the filter screen 20. Finally, the purified flue gas is discharged through the output pipe 13. A one-way valve can be installed at the end of the output pipe 13 to prevent the purified flue gas from flowing back.

[0037] By setting up a partition 14, the two sets of purification components can be separated from each other, so that each set of purification components can operate independently without interference. This ensures that when one set of purification components needs maintenance or inspection, the other set of purification components can continue to purify the flue gas without interruption. By setting the second flue 27 to move up or down along the inner wall of the first flue 8, when one set of purification components is under maintenance or inspection, the second flue 27 on it can be moved to a position that is misaligned with its corresponding connecting seat 30, so as to prevent the flue gas from entering the purification component during maintenance or inspection. At the same time, the size of the flue gas inlet can be adjusted by adjusting the relative opening between the second flue 27 and the connecting seat 30.

[0038] The support includes mounting plate 4 and mounting plate 5. Mounting plate 4 and mounting plate 5 are welded together by support rods 3 in series. The bottom of the housing 1 and the top of the support rods 3 are fixedly connected by screws. An electric telescopic rod 25 is fixed to the bottom outer wall of mounting plate 4 by screws. A U-shaped plate 23 is fixed to the output end of the electric telescopic rod 25 by a pin. A rotating rod 26 is rotatably connected between the two sides of the U-shaped plate 23. A self-locking motor 12 is fixed to one side outer wall of the U-shaped plate 23 by screws. The output end of the self-locking motor 12 is connected to one end of the rotating rod 26 by a coupling. A sliding plate 24 is fixed to the outer circumference of the rotating rod 26 by screws. Sliding sleeves 22 are slidably connected to both ends of the sliding plate 24. The sliding sleeves 22 and the bottom of the sliding plate 7 are rotatably connected by a rotating shaft.

[0039] The self-locking motor 12 drives the sliding sleeve 22 and the sliding plate 24 to rotate via the rotating rod 26. The sliding sleeve 22 and the sliding plate 24 convert the circular motion of the rotating rod 26 into the longitudinal linear motion of the sliding plate 7 along the corresponding housing 1. The two sliding plates 7 move in opposite directions, that is, when one sliding plate 7 moves up, the other sliding plate 7 moves down. When the self-locking motor 12 does not drive the rotating rod 26 to rotate, the electric telescopic rod 25 drives the two sliding plates 7 to move up or down synchronously.

[0040] A vibration mechanism is installed between the two sides of the housing 1. The vibration mechanism includes a rotating shaft 6, a mounting ring 35, a rubber head 36, and a hammer rod 37. The rotating shaft 6 is rotatably connected to the inner wall of the through holes on both sides of the housing 1. The mounting ring 35 is welded to the outer circumference of the rotating shaft 6. The hammer rod 37 is welded to the bottom of the mounting ring 35. The rubber head 36 is fixed to the end of the hammer rod 37 by embedding. The vibration mechanism also includes a limit cover 10 and a coil spring 16. The limit cover 10 is fixed to the end of the rotating shaft 6 by screws. The coil spring 16 is sleeved on the outer circumference of the rotating shaft 6, and both ends of the coil spring 16 are respectively fixed between the housing 1 and the limit cover 10.

[0041] After the filter screen 20 has been used for a period of time, the particles attached to its surface need to be cleaned. During cleaning, the sliding plate 7 is driven to move up or down along its corresponding housing 1 by the self-locking motor 12 or the electric telescopic rod 25. During the up and down movement of the sliding plate 7, the rotating shaft 6 is rotated along the housing 1 by external force. During the rotation of the rotating shaft 6, the coil spring 16 undergoes elastic deformation in the circumferential direction, causing the rubber head 36 and the hammer rod 37 to move away from the filter screen 20. When the coil spring 16 stores a certain amount of elastic potential energy, it releases the rotating shaft 6. The elastic potential energy stored in the spring 16 is converted into the kinetic energy of the rubber head 36. Under the action of the rebound force of the coil spring 16, the rubber head 36 strikes the surface of the filter screen 20. By increasing the length of the hammer rod 37, the rotating shaft 6 can rotate at a small angle, and the rubber head 36 can swing at a large angle. Since the filter screen 20 is fixed between the flexible strip 34 and the sliding plate 7, the filter screen 20 will vibrate during the striking process. The flexible strip 34 can be made of rubber or sponge. After being vibrated, the particles attached to the surface of the filter screen 20 will be shaken off the surface of the filter screen 20 more quickly.

[0042] An extension rod 33 is fixed to one side of the outer wall of the sliding plate 7 by screws. A conductive component 32 is fixed to one end of the extension rod 33 by screws. A vertical plate 28 is fixed to the top outer wall of the housing 1 by screws. Multiple sets of conductive track components 29 that cooperate with the conductive component 32 are fixed to the side of the vertical plate 28 by screws. A connecting plate 15 is fixed to one side of the outer wall of the housing 1 by screws. An electromagnet 39 is fixed to the bottom of the connecting plate 15 by screws. A drive plate 11 is fixed to one end of the rotating shaft 6 by screws. A permanent magnet 38 that cooperates with the electromagnet 39 is fixed to the top of the drive plate 11 by screws.

[0043] Electromagnet 39 and conductive component 32 are electrically connected. When sliding plate 7 moves up or down, conductive component 32 moves synchronously up or down with sliding plate 7. Conductive rail components 29 with a certain distance are installed on vertical plate 28. Conductive rail components 29 contain energized conductive copper strips. Elastic conductive contacts are installed on the surface of conductive component 32. One end or middle of conductive rail component 29 is connected to a power source. Current flows through wires into the pre-set conductive copper strips inside conductive rail component 29. Each conductive rail component 29 contains at least two copper strips 9 (neutral and live wires). The position of the elastic conductive contacts on conductive component 32 precisely corresponds to the copper strips inside conductive rail component 29. During movement, the elastic conductive contacts of conductive component 32... The electrical contacts will make tight and stable contact with the conductive copper strips in the conductive track 29 to form an electrical connection. There are insulating grooves between the conductive copper strips on the conductive track 29 to prevent short circuits. When the circuit is turned on, the current flows from the copper strips of the conductive track 29 through the spring to the electromagnet 39, so that the electromagnet 39 is energized and generates a magnetic force to attract the permanent magnet 38. After the permanent magnet 38 is attracted, the rotating shaft 6 rotates, which in turn causes the rubber head 36 to move away from the filter screen 20. When the conductive component 32 moves to the gap between two adjacent conductive track components 29, since the conductive component 32 is not in contact with the conductive track component 29, the electromagnet 39 is de-energized. Then, the rubber head 36 knocks and vibrates the filter screen 20 under the action of the spring force of the coil spring 16.

[0044] When the conductive component 32 moves again to contact the other conductive track components 29, the electromagnet 39 is energized again to attract the permanent magnet 38, causing the rubber head 36 to reciprocate to strike the filter screen 20. Because the filter screen 20 moves up and down continuously during this process, the position of the rubber head 36 striking the filter screen 20 will change each time, so that the rubber head 36 strikes the filter screen 20 at different heights evenly, so that the particles attached to different positions on the filter screen 20 can be evenly knocked off.

[0045] The inner surface of the sliding plate 7 is fixed with a connecting plate 18 by screws, and the end of the connecting plate 18 away from the sliding plate 7 is fixed with an inclined plate 19 by screws.

[0046] When it is necessary to clean the particles shaken off the filter screen 20, the inclined plate 19 is fixedly connected to the side of the sliding plate 7 by the connecting plate 18, so that the inclined plate 19 can move up or down synchronously with the sliding plate 7. When the sliding plate 7 drives the inclined plate 19 to move down, a certain gap is formed between the inclined plate 19 and the bottom of the housing 1, so that the shaken particles can slide down the inclined surface of the inclined plate 19 from the bottom of the housing 1.

[0047] The inclined plate 19 has a certain thickness, so when the sliding plate 7 moves up or down, and the flue hole 31 on the flue 27 adjusts its opening and closing with the connecting seat 30, the inclined plate 19 will block the bottom opening of the housing 1, so as to prevent the flue gas from being discharged from the bottom opening of the housing 1 when the flue gas is being purified.

[0048] When one housing 1 is cleaning particulate matter while the other housing 1 continues to purify flue gas, the self-locking motor 12 drives the two sets of sliding plates 7 to move in opposite directions. One of the sliding plates 7 is higher and the other is lower. Therefore, when the smoke hole 31 on the side of one flue duct 27 is aligned with the connecting seat 30, the smoke hole 31 on the side of the other flue duct 27 is located below the connecting seat 30. Furthermore, there is a gap between the inclined plate 19 corresponding to this flue duct 27 and the bottom of the housing 1. Thus, when one housing 1 is cleaning particulate matter while the other housing 1 continues to purify flue gas, the entire purification process will not be interrupted due to the cleaning of particulate matter.

[0049] A controller 2 is installed on the side of the housing 1. The controller 2 is used to control the self-locking motor 12 and the electric telescopic rod 25 to drive the sliding plate 7 and the filter screen 20 to move, and to link the vibration mechanism to clean the filter screen 20.

[0050] A purification method for treating particulate matter in industrial kilns includes the following steps: S1: The flue gas is diverted through the input pipe 9 to the two connecting seats 30 and enters the flue 1 8. The drive sliding plate 7 drives the flue 27 to move up and down in the flue 1 8, adjusting the opening and closing of its side smoke hole 31 and the corresponding connecting seat 30. The flue gas enters the flue 27 through the aligned smoke hole 31 and is introduced into the inner cavity of the housing 1.

[0051] S2: The flue gas passes through the filter screen 20 inside the housing 1 and is filtered, and the clean flue gas is discharged from the output pipe 13.

[0052] S3: Controller 2 controls the self-locking motor 12 or electric telescopic rod 25 to drive the sliding plate 7 to move longitudinally. When the sliding plate 7 moves, it drives the conductive component 32 to slide along the conductive track 29 on the vertical plate 28. When the conductive component 32 contacts the conductive track 29, the circuit is turned on, which energizes the electromagnet 39 and attracts the permanent magnet 38, which drives the rotating shaft 6 to rotate and causes the coil spring 16 to store energy. When the conductive component 32 slides to the gap of the conductive track 29, the power is cut off, the electromagnet 39 loses magnetism, which causes the coil spring 16 to drive the rotating shaft 6 to rotate, so that the rubber head 36 at the end of the hammer rod 37 strikes the filter screen 20. The flexible connection of the filter screen 20 generates vibration to shake off surface particles.

[0053] S4: When the shaken-off particles move down the sliding plate 7, they are guided by the inclined plate 19 on its side and slide out from the bottom opening of the housing 1, achieving cleaning without stopping the machine.

[0054] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

Both ends of the sliding plate (24) are movably connected with sliding sleeves (22), and the sliding sleeves (22) and the bottom of the sliding plate (7) are movably connected by a rotating shaft.

9. A purification device for treating particulate matter in industrial kilns according to claim 1 or 8, characterized in that, The controller (2) is mounted on the side of the housing (1).

10. A purification method for treating particulate matter in industrial kilns, comprising purifying using the purification device described in any one of claims 1-9, characterized in that, Includes the following steps: S1: The flue gas is diverted to two connecting seats (30) through the input pipe (9) and enters flue one (8). The second flue (27) is driven up and down in flue one (8) by the drive sliding plate (7). The opening and closing of the side flue hole (31) and the corresponding connecting seat (30) are adjusted. The flue gas enters the second flue (27) through the aligned flue hole (31) and is introduced into the inner cavity of the housing (1). S2: The flue gas passes through the filter screen (20) inside the shell (1) and is filtered, and the clean flue gas is discharged from the output pipe (13); S3: The controller (2) controls the self-locking motor (12) or electric telescopic rod (25) to drive the sliding plate (7) to move longitudinally. When the sliding plate (7) moves, it drives the conductive component (32) to slide along the conductive track (29) on the upright plate (28). When the conductive component (32) contacts the conductive track (29), the circuit is turned on, which energizes the electromagnet (39) and attracts the permanent magnet (38), which drives the rotating shaft (6) to rotate and makes the coil spring (16) store energy. When the conductive component (32) slides to the gap of the conductive track (29) and is de-energized, the electromagnet (39) loses magnetism, which causes the coil spring (16) to drive the rotating shaft (6) to rotate, so that the rubber head (36) at the end of the hammer rod (37) strikes the filter screen (20). The flexible connection of the filter screen (20) generates vibration to shake off surface particles. S4: When the shaken particles move down the sliding plate (7), they are guided by the inclined plate (19) on its side and slide out from the bottom opening of the housing (1), thus achieving cleaning without stopping the machine.
