Description

A desulfurization device for flue gas from carbide slag in cement production Technical Field

[0001] This invention relates to the field of flue gas desulfurization equipment technology, and in particular to a flue gas desulfurization equipment for cement production using carbide slag. Background Technology

[0002] In the operation of flue gas desulfurization units for cement production using carbide slag, the demister layer inside the desulfurization tower is a key structure for treating clean flue gas. Upon contact with flue gas containing impurities, carbide slag particles, calcium sulfite generated during the desulfurization reaction, and calcium sulfate, among other impurities, easily adhere to its surface and gradually accumulate. Existing demister layers mostly employ fixed corrugated plate structures, making it difficult to clean the accumulated impurities easily. This requires manual entry into the tower after the machine is shut down, which is not only difficult and creates a harsh working environment but also affects the continuous operating efficiency of the unit. Furthermore, long-term accumulation of impurities can clog the demister layer channels, increasing flue gas flow resistance, reducing the demister effect, and accelerating the wear and corrosion of the demister layer structure, shortening the equipment's service life and failing to meet the requirements for efficient and stable operation of the carbide slag desulfurization process. Summary of the Invention

Arc-shaped grooves are provided on the inner wall of the two sets of triangular sleeves corresponding to the notches. Several sets of corrugated plates are fixedly installed on the inner side of the demisting frame corresponding to the position of the demisting frame.

[0006] Preferably, the driving assembly includes a shielding sleeve fixedly disposed between two sets of notches. Both ends of the shielding sleeve are fitted with shielding plates. Fixing blocks are fixedly disposed on both sides of the two sets of shielding plates. A fixing rod is fixedly disposed on the upper end of each fixing block.

Two sets of support rods are fixedly disposed on the upper inner wall of the shielding sleeve. Rotating rods are movably disposed on the inner sides of the two sets of support rods. A motor is fixedly disposed on the fixing plate. A spur gear is fixedly disposed on one end of the motor's rotating shaft and the rotating rod. A fixing sleeve is fixedly disposed near the middle position on the upper inner wall of the shielding sleeve. A movable shaft is rotatably disposed on the inner side of the fixing sleeve. Bevel gears are fixedly disposed on the outer side of the movable shaft and the other end of the rotating rod. Two sets of push rods are fixedly disposed on the lower side of the movable shaft.

[0007] Preferably, the telescopic component includes two sets of circular sleeves fixedly installed in each of the four sets of mounting cavities. A fixed shaft is fixedly installed on the inner side of each circular sleeve, and a spiral spring sheet is wound inside the fixed shaft. An opening is provided on the outer side of each circular sleeve, and a movable opening is provided in the middle of each spiral spring sheet.

[0008] Preferably, the slag removal assembly includes two sets of movable blocks symmetrically arranged between two sets of corrugated plates. A slag blade is fixedly installed on the opposite side of each set of movable blocks. A movable groove is opened on the inner side of each movable block. A roller is rotatably installed on the inner side of the movable groove. A right-angle shaft is fixedly installed at the upper and lower ends of each movable block. Two sets of hemispheres are fixedly installed on the right-angle shaft.

[0009] Preferably, the two sets of mounting cavities are mirror-symmetrically arranged, the arc-shaped groove satisfies the rotational movement of the push rod, and the several sets of wave plates are evenly distributed and arranged.

[0010] Preferably, the notch of the shielding sleeve communicates with the interior of the mounting cavity, the shielding plate fits against the shielding sleeve and covers the movable block together, the fixed block is located inside the arc groove, the fixed rod passes through the inner wall of the mounting cavity to the annular sleeve, the hydraulic cylinder is fixedly connected to the inner wall of the mounting cavity and the telescopic rod is connected to the fixed plate, the two sets of column gears are meshed, the two sets of bevel gears are meshed, the two sets of push rods are located between the front and rear spiral spring plates and staggered from the movable opening position, and a certain distance is set between the two ends of the push rod and the edge of the wave plate when the push rod rotates.

[0011] Preferably, the fixed shaft is fixedly connected to the inner end of the wound spiral spring sheet, and the two sets of symmetrical spiral spring sheets in the mounting cavities on both sides of the triangular sleeve are fixedly connected as an integral structure on one side of the push rod, and the opening allows the spiral spring sheet to pass through.

[0012] Preferably, the two sets of movable blocks are attached together, the shovel is attached to the surface of the corrugated plate, the roller is attached to the surface of the corrugated plate, the right-angle shaft is inserted into the movable opening, and the two sets of hemispherical restrictive spiral spring plates on the right-angle shaft are attached to both ends.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The sprayer reacts with the cement fumes entering through the air inlet pipe. The corrugated plate, with its corrugated structure, allows the fumes carrying slurry droplets to repeatedly change direction as they pass through the channel between the plates. The droplets are impacted by inertial force and aggregate into larger droplets, eventually flowing down the plate surface, thus separating the clean fumes from the droplets. The triangular sleeve guides the fumes onto the corrugated plate and discharges them down.

[0015] 2. When it is necessary to treat the impurities accumulated on the corrugated plate, the use of hydraulic cylinders on both sides can move the fixed plate, fixed rod, fixed block, and baffle plate up or down, thereby opening or closing the two sides of the baffle sleeve. Opening the two sides of the baffle sleeve facilitates the rotation of the push rod, while closing the push rod and the spiral spring plate protects it from contact with mud and other impurities, preventing them from affecting its use. The motor drives the connected spur gear to rotate, which in turn drives the rotating rod and the bevel gear at one end to rotate. The rotating bevel gear then drives the meshing bevel gear, the movable shaft, and the two sets of push rods to rotate. The two sets of push rods rotate between the front and rear spiral spring plates, causing the spiral spring plates to expand and contract in a circular motion, thereby pushing several sets of movable blocks to move and treat the impurities accumulated on the corrugated plate. When the push rod rotates, there is a certain distance between it and the edge of the corrugated plate, which allows the movable blocks to move to the distance between the rotating end of the push rod and the edge of the corrugated plate, enabling the push rod to rotate normally.

[0016] 3. The scroll spring is pushed and stretched, causing the scroll spring on one side of the sleeve to be elastically wound up. The elastic structure of the scroll spring being wound up allows the deformation that pushes the scroll spring and several sets of movable blocks to move when the push rod rotates, and the final elastic stretch can pull it back.

[0017] 4. Two sets of symmetrical movable blocks between the two sets of wave plates are connected to the spiral spring plates via a right-angle shaft. They are pushed by the rotating push rod and, together with the rollers, roll on the wave plates, causing the two sets of symmetrical movable blocks to be pushed to both sides. The scraper removes impurities from the surface of the wave plates. With the rotation of the push rod, several sets of movable blocks can be moved to different positions, fitting closer to the edges of the circular wave plates, resulting in more thorough cleaning.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to 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 as a relative relationship of orientation or position, and 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, and therefore should not be construed as a limitation of this invention.

[0034] Please refer to Figures 1-13. One embodiment of the present invention provides a desulfurization device for flue gas from carbide slag cement production, comprising a spray tower device 1. An air inlet pipe 2 is fixedly installed on one side of the spray tower device 1. An exhaust pipe 3 is fixedly installed on the upper side of the spray tower device 1 near the front. A sprayer 4 is fixedly installed inside the spray tower device 1. A demisting component 5 is installed inside the spray tower device 1, below the sprayer 4. Two sets of drive components 6 are installed in the middle of the demisting component 5. Telescopic components 7 are installed inside the demisting component 5 at both the upper and lower sides. A slag-scraping component 8 is installed in the middle of the demisting component 5. The demisting component 5 includes a fixed... A demisting frame 51 is installed inside the spray tower equipment 1. A circular ring sleeve 52 is provided in the middle of the demisting frame 51. Triangular sleeves 53 are provided on both the upper and lower sides of the demisting frame 51. An installation cavity 54 is provided on both sides of the two sets of triangular sleeves 53. A fixing plate 55 is fixedly installed in the installation cavity 54 on one side of the two sets of triangular sleeves 53. Several sets of outlets 56 are opened on the lower set of the two sets of triangular sleeves 53. Two sets of notches 57 are opened symmetrically on the inner wall of the two sets of installation cavities 54. Arc grooves 58 are provided on the inner wall of the two sets of triangular sleeves 53 corresponding to the notches 57. Several sets of corrugated plates 59 are fixedly installed on the inner side of the demisting frame 51 corresponding to the position of the demisting frame 51.

[0035] The two sets of mounting cavities 54 are mirror-symmetrically arranged, the arc-shaped groove 58 satisfies the rotational movement of the push rod 614, and several sets of wave plates 59 are evenly distributed.

[0036] The sprayer 4 reacts with the cement flue gas entering through the air inlet pipe 2. The corrugated plate 59, with its corrugated structure, allows the flue gas carrying slurry droplets to repeatedly change direction as it passes through the inter-plate channel. The droplets are impacted by inertial force and aggregate into large droplets, eventually flowing down the plate surface, thus separating the clean flue gas from the droplets. The triangular sleeve 53 guides the flue gas onto the corrugated plate 59 and discharges it down.

[0037] The drive assembly 6 includes a shielding sleeve 61 fixedly disposed between two sets of notches 57. Both ends of the shielding sleeve 61 are fitted with shielding plates 62. Fixing blocks 63 are fixedly disposed on both sides of the two sets of shielding plates 62. Fixing rods 64 are fixedly disposed on the upper ends of the fixing blocks 63. Fixing plates 65 are fixedly disposed on the upper ends of the two sets of fixing rods 64 on both sides of the shielding sleeve 61. Hydraulic cylinders 66 are fixedly disposed on both sets of fixing plates 65. Two sets of support rods 67 are fixedly disposed on the upper inner wall of the shielding sleeve 61. A rotating rod 68 is movably installed inside the support rod 67. A motor 69 is fixedly installed on the fixed plate 55. A spur gear 610 is fixedly installed on one end of the rotating shaft of the motor 69 and the rotating rod 68. A fixed sleeve 611 is fixedly installed on the upper inner wall of the shielding sleeve 61 near the middle position. A movable shaft 612 is rotatably installed inside the fixed sleeve 611. A bevel gear 613 is fixedly installed on the outer side of the movable shaft 612 and the other end of the rotating rod 68. Two sets of push rods 614 are fixedly installed on the lower side of the movable shaft 612.

[0038] The shielding sleeve 61 is connected to the inside of the mounting cavity 54 at the position corresponding to the notch 57. The shielding plate 62 fits against the shielding sleeve 61 and covers the movable block 81 together. The fixed block 63 is located inside the arc groove 58. The fixed rod 64 passes through the inner wall of the mounting cavity 54 to the annular sleeve 52. The hydraulic cylinder 66 is fixedly connected to the inner wall of the mounting cavity 54 and the telescopic rod is connected to the fixed plate 65. The two sets of column gears 610 are meshed. The two sets of bevel gears 613 are meshed. The two sets of push rods 614 are located between the front and rear spiral spring plates 73 and are staggered from the movable opening 75. When the two ends of the push rod 614 rotate, a certain distance is set between them and the edge of the wave plate 59.

[0039] When it is necessary to treat the impurities accumulated on the corrugated plate 59, the use of the hydraulic cylinders 66 on both sides can move the fixing plate 65, fixing rod 64, fixing block 63, and baffle plate 62 up or down, thereby opening or closing the two sides of the baffle sleeve 61. Opening the two sides of the baffle sleeve 61 facilitates the rotation of the push rod 614, while closing the push rod 614 and the spiral spring plate 73 prevents contact with mud and other impurities, thus affecting its use. The motor 69 drives the connected spur gear 610 to rotate, and the meshing spur gear 610 drives the rotating rod 68 and the bevel gear 613 at one end to rotate. The rotating bevel gear 613 drives the meshing bevel gear 613, the movable shaft 612, and the two sets of push rods 614 to rotate. The two sets of push rods 614 rotate between the front and rear spiral spring plates 73, causing the spiral spring plates 73 to expand and contract in a circular motion. This pushes several sets of movable blocks 81 to move, thus processing the impurities accumulated on the wave plate 59. When the push rod 614 rotates, there is a certain distance between it and the edge of the wave plate 59, which allows the movable blocks 81 to move between the rotating end of the push rod 614 and the edge of the wave plate 59, so that the push rod 614 can rotate normally.

[0040] The telescopic assembly 7 includes two sets of circular sleeves 71 fixedly installed in each of the four sets of mounting cavities 54. A fixed shaft 72 is fixedly installed on the inner side of the circular sleeve 71. A spiral spring sheet 73 is wound inside the fixed shaft 72. An opening 74 is opened on the outer side of the circular sleeve 71. An movable opening 75 is opened in the middle position of the spiral spring sheet 73.

[0041] The fixed shaft 72 is fixedly connected to the inner end of the wound spiral spring sheet 73. The two sets of symmetrical spiral spring sheets 73 in the mounting cavities 54 on both sides of the triangular sleeve 53 are fixedly connected as a whole structure and are on the side of the push rod 614. The opening 74 allows the spiral spring sheet 73 to pass through.

[0042] The scroll spring plate 73 is pushed and stretched, causing the scroll spring plate 73 on one side of the sleeve 71 to be elastically wound up. The elastic structure of the scroll spring plate 73 being wound up allows the deformation of the scroll spring plate 73 and several sets of movable blocks 81 to move when the push rod 614 rotates, and the final elastic stretch can pull it back.

[0043] The slag removal assembly 8 includes two sets of movable blocks 81 symmetrically arranged between two sets of corrugated plates 59. Each set of movable blocks 81 has a slag blade 82 fixedly installed on the opposite side. The inner side of the movable block 81 has a movable groove 83. A roller 84 is rotatably installed inside the movable groove 83. A right-angle shaft 85 is fixedly installed at the upper and lower ends of the movable block 81. Two sets of hemispheres 86 are fixedly installed on the right-angle shaft 85.

[0044] Two sets of movable blocks 81 are attached together, the scraper 82 is attached to the surface of the wave plate 59, the roller 84 is attached to the surface of the wave plate 59, the right-angle shaft 85 is inserted into the movable opening 75, and the two sets of hemispheres 86 on the right-angle shaft 85 restrict the two ends of the spiral spring plate 73.

[0045] Two sets of movable blocks 81, symmetrically positioned between the two sets of wave plates 59, are connected to the spiral spring plate 73 via a right-angle shaft 85. They are pushed by the rotating push rod 614 and, in conjunction with the roller 84, roll on the wave plates 59. This causes the two sets of movable blocks 81 to be pushed to both sides, where the scraper 82 scrapes off impurities from the surface of the wave plates 59. Furthermore, with the rotation of the push rod 614, several sets of movable blocks 81 can be moved to different positions, fitting more closely to the edges of the circularly arranged wave plates 59, resulting in a more thorough cleaning.

[0046] Working principle: During use, the sprayer 4 reacts with the cement flue gas entering through the air inlet pipe 2. The corrugated plate 59, with its corrugated structure, allows the flue gas carrying slurry droplets to repeatedly change direction as it passes through the inter-plate channel. Due to inertial force, the droplets impact the plate surface and aggregate into larger droplets, eventually flowing down the plate surface, thus separating the clean flue gas from the droplets. The triangular sleeve 53 guides the droplets onto the corrugated plate 59 and discharges them. Furthermore, when it is necessary to treat impurities accumulated on the corrugated plate 59, the hydraulic cylinders 66 on both sides can be used to fix the plate 65, the fixing rod 64, and the fixing... Block 63 and baffle 62 move up or down, thereby opening or closing the two sides of the baffle sleeve 61. Opening the two sides of the baffle sleeve 61 facilitates the rotation of the push rod 614, while closing the push rod 614 and the spiral spring plate 73 prevents contact with mud and other impurities, thus avoiding their impact on future use. The motor 69 drives the connected spur gear 610 to rotate, which in turn drives the rotating rod 68 and the bevel gear 613 at one end to rotate. The rotating bevel gear 613 then drives the meshing bevel gear 613, the movable shaft 612, and the two sets of push rods 614 to rotate. The two sets of push rods 614 rotate back and forth. The rotation of the side scroll spring plates 73 causes them to expand and contract in a circular motion, thereby pushing several sets of movable blocks 81 to move and process the impurities accumulated on the wave plate 59. When the push rod 614 rotates, there is a certain distance between it and the edge of the wave plate 59, allowing the movable blocks 81 to move between the rotating end of the push rod 614 and the edge of the wave plate 59, enabling the push rod 614 to rotate normally. Simultaneously, the scroll spring plates 73 are pushed and stretched, causing one side of the scroll spring plate 73 in the circular sleeve 71 to spring back. The elastic structure of the spring plate 73 allows the push rod 614 to push when it rotates. The moving scroll spring plate 73 and several sets of movable blocks 81 deform as they move, and the final elastic stretch can pull them back; while the two sets of movable blocks 81 symmetrically located between the two sets of wave plates 59 are connected to the scroll spring plate 73 through the right-angle shaft 85 and are pushed by the rotating push rod 614. In conjunction with the roller 84, they roll on the wave plate 59, so that the two sets of movable blocks 81 are pushed to both sides respectively. The scraper 82 scrapes off the impurities on the surface of the wave plate 59. With the rotation of the push rod 614, several sets of movable blocks 81 can be moved to different positions, more closely fitting the edges of the several sets of circularly arranged wave plates 59, and cleaning more thoroughly.

[0047] The electrical connection and control of the spray tower equipment 1, air inlet pipe 2, exhaust pipe 3, sprayer 4, corrugated plate 59, hydraulic cylinder 66, and motor 69 in this invention are common knowledge in the field. Their working principle is already known technology, and the appropriate model is selected according to actual use, so it will not be explained in detail.
