Description

Technical Field

[0001] This invention relates to the field of flue gas desulfurization technology, specifically a desulfurization device based on lithium mica sintering flue gas. Background Technology

[0002] Lithium mica sintering is a process for processing lepidolite ore. During the sintering process, a large amount of flue gas containing pollutants such as sulfur dioxide is generated. If this flue gas is not effectively desulfurized, direct emission will cause serious environmental pollution and lead to environmental problems such as acid rain. Therefore, it is necessary to desulfurize the flue gas generated after sintering lepidolite.

[0003] Currently, wet desulfurization is commonly used to treat flue gas. This involves passing flue gas into a desulfurization tower and spraying desulfurization slurry in an atomized form through a spraying device. At the same time, a swirl plate is installed inside the desulfurization tower so that the flue gas rises in a spiral manner and comes into contact with the atomized slurry to enhance gas-liquid contact and achieve desulfurization of the flue gas.

[0004] The following problems may exist in the current flue gas desulfurization treatment: 1. Since the swirl blades of the cyclone plate are usually at a fixed angle, and the flue gas may be unevenly distributed in the desulfurization tower, the atomized slurry cannot fully contact and react with the flue gas, affecting the flue gas desulfurization efficiency; 2. The flue gas may contain particulate impurities such as ore dust and solid products after reaction. When the flue gas passes through the cyclone plate, the particulate impurities in the flue gas may wash away the cyclone plate, causing wear and tear, which in turn affects the service life of the cyclone plate.

Multiple circumferentially evenly arranged transmission blocks are fixedly mounted on the upper end of the transmission circular plate. Transmission connecting rods are fixedly mounted on opposite sides of the multiple disturbance rods, and the opposite sides of the multiple transmission connecting rods are rotatably connected to the transmission rod.

[0008] Preferably, two symmetrically arranged pressing and engaging columns are fixedly installed on the outer side of the transmission circular plate, and multiple circumferentially evenly arranged pressing blocks are fixedly installed on the inner side of the rotating shaft. The lower end of the pressing blocks is configured as an inclined surface for driving the pressing and engaging columns to move downward.

[0009] Preferably, the angle adjustment mechanism includes a bevel gear one installed on opposite sides of the rotating shafts of multiple swirl blades via a key engagement, a bevel gear two meshing on the lower side of the multiple bevel gears, a connecting column fixedly installed at the lower end of the bevel gear two, and multiple circumferentially evenly arranged guide rods fixedly installed on the outer side of the connecting column. The opposite sides of the multiple guide rods are slidably installed in a pre-set arc groove on the inner wall of the rotating shaft via arc springs.

[0010] Preferably, a driven circular plate is fixedly installed at the lower end of the connecting column, and a plurality of circumferentially evenly arranged driven blocks are fixedly installed at the lower end of the driven circular plate. The driven blocks are used to cooperate with the transmission block to drive the driven circular plate to rotate.

[0011] Preferably, the disturbance reinforcement rod group includes a plurality of disturbance reinforcement rods that are fixedly installed on the outside of the disturbance rod and are evenly arranged in a circumferential direction.

[0012] Preferably, the intermittent slag discharge mechanism includes a slag discharge plate fixedly sleeved on the outside of the impurity removal plate.

A reset spring is connected between the fixed plates and the desulfurization tower. Multiple circumferentially evenly arranged slag discharge holes are opened on the slag discharge plate.

[0013] Preferably, a plurality of L-shaped mating plates arranged circumferentially are fixedly installed on the annular electric slider assembly and below the disturbance rod, and a plurality of circumferentially arranged lower pressure plates are fixedly installed on the upper side of the slag discharge plate, with the upper end of the lower pressure plate being configured as an inclined surface for mating with the mating plates.

[0015] The beneficial effects of the present invention are as follows: 1. The present invention sets up multiple disturbance rods to disturb the flue gas by revolving, so that the flue gas can be evenly distributed and rise through the flue gas guiding unit. At the same time, the present invention sets up a transmission mechanism and an angle adjustment mechanism to drive the swirl blades to change the angle intermittently, thereby enhancing the turbulence of the flue gas, promoting the full contact and reaction between the flue gas and the atomized slurry, and improving the desulfurization efficiency of the flue gas.

[0016] 2. This invention removes particulate impurities from flue gas by setting impurity removal holes on the impurity removal plate. The upper end of the impurity removal holes is arranged inclined towards the middle of the impurity removal plate, which facilitates the downward sliding of particulate impurities in the flue gas along the inclined structure of the impurity removal holes under the action of gravity, preventing the particulate impurities in the flue gas from clogging the impurity removal holes, thereby ensuring the continuous removal of particulate impurities in the flue gas and ensuring the service life of the swirl blades.

[0017] 3.

[0018] 4. The present invention uses a matching plate and a lower pressure plate to drive the impurity removal plate to shake up and down, thereby ensuring that the particulate impurities on the impurity removal plate can slide down along the spherical surface at the upper end of the impurity removal plate to the slag discharge plate, while preventing impurities from clogging the impurity removal holes of the impurity removal plate, thus ensuring the continuous removal of impurity particles in the flue gas.

[0028] The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Where no specific technology or conditions are specified in the embodiments, they shall be performed in accordance with the technology or conditions described in the literature in the field or in accordance with the product manual.

[0029] See Figure 1 and Figure 2 A desulfurization device based on sintering flue gas from lithium mica includes a desulfurization tower 1, a spray unit 2 installed inside the desulfurization tower 1, a flue gas guiding unit 3 installed inside the desulfurization tower 1 and below the spray unit 2, a disturbance unit 4 installed between the flue gas guiding unit 3 and the desulfurization tower 1, and a cleanup unit 5 installed inside the desulfurization tower 1 and below the disturbance unit 4.

[0030] It should be noted that, in this invention, a flue gas inlet is installed on the lower left side of the desulfurization tower 1, and a flue gas outlet is installed on the upper end of the desulfurization tower 1. A slurry inlet pipe and a slurry outlet pipe are respectively installed on the left and right sides of the lower part of the desulfurization tower 1. The desulfurization slurry can be introduced into the desulfurization tower 1 through the slurry inlet pipe, and the spray unit 2 is connected to the desulfurization slurry in the desulfurization tower 1, so that the spray unit 2 can spray the desulfurization slurry downward in the form of atomization, so that the rising flue gas and the atomized flue gas can come into contact and react, and the desulfurization products can be discharged from the slurry outlet pipe.

[0031] This invention is used for desulfurization of flue gas generated during the sintering of lithium mica. This invention can first filter particulate impurities in the flue gas, thereby preventing the particulate impurities mixed in the flue gas from eroding and wearing the flue gas guiding unit 3, ensuring the service life of the flue gas guiding unit 3. At the same time, this invention can also disturb the flue gas, thereby making the flue gas evenly distributed, allowing the flue gas and the atomized slurry to fully contact and react, increasing the desulfurization effect of the flue gas.

[0032] Specifically, flue gas is first introduced into desulfurization tower 1. The flue gas rises from the bottom of desulfurization tower 1. The impurity removal unit 5 removes particulate impurities from the flue gas, causing them to fall to the bottom of desulfurization tower 1. Then, the flue gas after impurity removal passes through the disturbance unit 4. By activating the disturbance unit 4, the flue gas is continuously disturbed, allowing it to pass evenly through the flue gas guide unit 3. The flue gas spirals upward under the action of the flue gas guide unit 3. At the same time, the spray unit 2 is activated to atomize and spray out slurry, allowing the spiraling flue gas and the atomized slurry to fully contact and react, thus achieving desulfurization of the flue gas. The particulate impurities generated after the reaction between the atomized slurry and the flue gas fall downward onto the impurity removal unit 5. The impurity removal unit 5 can periodically remove the particulate impurities above it. The desulfurized flue gas can continue to rise and be discharged from desulfurization tower 1.

[0033] See Figure 2 , Figure 3 and Figure 5 The impurity removal unit 5 includes an impurity removal plate 51 with a spherical upper end distributed inside the desulfurization tower 1. The impurity removal plate 51 has a plurality of impurity removal holes arranged with the upper end inclined towards the middle of the impurity removal plate 51. The impurity removal plate 51 is connected to the desulfurization tower 1 through an intermittent slag discharge mechanism 52.

[0034] The impurity removal unit 5 is used to remove particulate impurities in the flue gas. Specifically, when the flue gas rises, it rises above the impurity removal plate 51 through the impurity removal holes. Since the upper end of the impurity removal holes is inclined towards the middle of the impurity removal plate 51, the flue gas moves along the inclined direction of the slag discharge hole. The inner wall of the impurity removal holes can intercept particulate impurities in the flue gas. The inclined impurity removal holes are conducive to the particulate impurities in the flue gas sliding down along the inclined structure of the impurity removal holes under the action of gravity, preventing the particulate impurities in the flue gas from clogging the impurity removal holes.

[0035] When the atomized slurry and flue gas come into full contact and react, the resulting particulate impurities can fall to the upper end of the impurity removal plate 51 and slide down the spherical surface of the upper end of the impurity removal plate 51 to the intermittent slag discharge mechanism 52, so that the intermittent slag discharge mechanism 52 can intermittently discharge the particulate impurities on the impurity removal plate 51 and let them fall into the lower part of the desulfurization tower 1.

[0036] See Figures 2-4 The disturbance unit 4 includes an annular electric slider assembly 41 installed in the desulfurization tower 1. Multiple disturbance rods 42 are installed in the annular electric slider assembly 41. Multiple groups of disturbance reinforcing rods 45 are fixedly installed on the outside of the disturbance rods 42 and are evenly arranged along their length. A cooperating mechanism 43 is installed between the opposite sides of the multiple disturbance rods 42 and the rotating shaft 33. The cooperating mechanism 43 is used to make the disturbance rods 42 revolve around the sun and rotate on their own axis at the same time.

[0037] The disturbance reinforcement rod assembly 45 includes multiple disturbance reinforcement rods that are fixedly installed on the outside of the disturbance rod 42 and are evenly arranged in the circumferential direction.

[0038] It should be noted that the annular electric slider assembly 41 in this invention includes a transmission ring, an annular slide rail, and an arc-shaped electric slider. The transmission ring is rotatably installed inside the desulfurization tower 1. The outer side of the transmission ring is fixedly connected to multiple circumferentially evenly arranged arc-shaped electric sliders. The multiple arc-shaped electric sliders are all slidably connected to the annular slide rail, and the annular slide rail is fixedly installed on the desulfurization tower 1. By starting the multiple arc-shaped electric sliders to slide along the annular slide rail, the multiple arc-shaped electric sliders drive the transmission ring to rotate around the center line reference of the desulfurization tower 1.

[0039] The disturbance unit 4 is used to disturb the flue gas. Specifically, the ring-shaped electric slider assembly 41 is activated to drive the disturbance rod 42 to revolve around the center line of the desulfurization tower 1. When the flue gas rises to the corresponding position of the disturbance rod 42, the rotating disturbance rod 42 can disturb the flue gas, making the flue gas evenly distributed. This allows the flue gas to rise evenly to the corresponding position of the flue gas guide unit 3. At the same time, under the action of the cooperating mechanism 43, the disturbance rod 42 can rotate around its center line, which in turn causes the disturbance rod 42 to drive the disturbance enhancement rod to rotate, increasing the disturbance effect on the flue gas and further ensuring the uniform distribution of the flue gas.

[0040] See Figure 2 and Figure 3 The intermittent slag discharge mechanism 52 includes a slag discharge plate 521 fixedly sleeved on the outside of the impurity removal plate 51. The outside of the slag discharge plate 521 is slidably connected to the desulfurization tower 1 through multiple circumferentially evenly arranged fixed plates. A reset spring 522 is connected between the fixed plates and the desulfurization tower 1. Multiple circumferentially evenly arranged slag discharge holes are opened on the slag discharge plate 521.

[0041] See Figures 2-4 On the annular electric slider assembly 41 and below the disturbance rod 42, a plurality of L-shaped mating plates 411 are fixedly installed in a circumferentially uniform manner. On the upper side of the slag discharge plate 521, a plurality of circumferentially uniformly arranged lower pressure plates 525 are fixedly installed. The upper end of the lower pressure plate 525 is set as an inclined surface for mating with the mating plates 411.

[0042] See Figure 5 A sealing plate 523 is rotatably installed at the lower end of the slag discharge plate 521. The sealing plate 523 has multiple circumferentially evenly arranged phase adjustment holes, which are initially staggered with the slag discharge holes. Multiple circumferentially evenly arranged mating blocks 524 are fixedly installed on the outer side of the sealing plate 523. The inner wall of the desulfurization tower 1 has mating grooves 11 at the positions corresponding to the mating blocks 524, and the mating blocks 524 are slidably installed in the mating grooves 11. The mating grooves 11 are set as inclined structures for mating with the mating blocks 524 to drive the sealing plate 523 to rotate.

[0043] The intermittent slag discharge mechanism 52 is used to intermittently discharge particulate impurities from the impurity removal plate 51. Specifically, after the atomized slurry and flue gas fully react, the generated particulate impurities can fall to the upper end of the impurity removal plate 51 and slide down the spherical surface of the upper end of the impurity removal plate 51 onto the slag discharge plate 521. Initially, the phase adjustment hole of the blocking plate 523 and the slag discharge hole of the slag discharge plate 521 are arranged alternately, so that the blocking plate 523 blocks the slag discharge hole of the slag discharge plate 521, thereby preventing the particulate impurities from falling downwards. At the same time, the flue gas cannot rise above the impurity removal plate 51 through the phase adjustment hole of the blocking plate 523 and the slag discharge hole of the slag discharge plate 521, thus ensuring that the flue gas can rise above the impurity removal plate 51 through the slag discharge hole of the impurity removal plate 51.

[0044] When the annular electric slider assembly 41 is activated, it drives the disturbance rod 42 to revolve around the center line of the desulfurization tower 1. The annular electric slider assembly 41 drives the mating plate 411 to rotate synchronously. When the mating plate 411 rotates to the corresponding position of the lower pressure plate 525, the inclined surfaces of the mating plate 411 and the lower pressure plate 525 engage to drive the slag discharge plate 521 and the impurity removal plate 51 to move downwards and compress the reset spring 522 through the fixed plate. When the mating plate 411 and the lower pressure plate 525 separate, the slag discharge plate 521 and the impurity removal plate 51 spring back to their initial positions under the action of the reset spring 522, thereby realizing the up-and-down shaking of the impurity removal plate 51. This ensures that the particulate impurities on the impurity removal plate 51 can slide down along the spherical surface at the upper end of the impurity removal plate 51 onto the slag discharge plate 521, while preventing the particulate impurities from clogging the impurity removal holes of the impurity removal plate 51.

[0045] When the slag discharge plate 521 moves downward, it drives the sealing plate 523 to move downward. At the same time, the inclined structure of the cooperating block 524 and the cooperating groove 11 drives the sealing plate 523 to rotate, so that the phase adjustment hole of the sealing plate 523 and the slag discharge hole of the slag discharge plate 521 are aligned, thereby allowing the impurities on the slag discharge plate 521 to fall into the lower part of the desulfurization tower 1.

[0046] See Figure 2 , Figure 3 and Figure 6 The flue gas guiding unit 3 includes an installation ring 31 fixedly installed inside the desulfurization tower 1. A rotating shaft 33 is distributed in the middle of the inner side of the installation ring 31. Multiple circumferentially evenly arranged swirl blades 32 are rotatably installed on opposite sides of the installation ring 31 and the rotating shaft 33. An angle adjustment mechanism 34 is installed between the opposite sides of the multiple swirl blades 32 and the rotating shaft 33. The swirl blades 32 are initially in an inclined state.

[0047] See Figure 6 Multiple disturbance rods 42 are also equipped with a transmission mechanism 44 on opposite sides. The transmission mechanism 44 is used to cooperate with the angle adjustment mechanism 34 to drive the swirl blades 32 to change angle.

[0048] The flue gas guiding unit 3 is used to make the flue gas spiral upward. Specifically, when the flue gas rises through the swirl blades 32, the flue gas spirals upward under the action of the inclined swirl blades 32, thereby ensuring that the atomized slurry and flue gas fully contact and react. At the same time, under the cooperation of the transmission mechanism 44 and the angle adjustment mechanism 34, the swirl blades 32 are driven to change their angle periodically, thereby enhancing the turbulence of the flue gas, further promoting the full contact and reaction between the flue gas and the atomized slurry, and improving the desulfurization efficiency of the flue gas.

[0049] See Figure 3 and Figure 6 The mating mechanism 43 includes a connecting cylinder 431 fixedly installed at the lower end of the rotating shaft 33. A driving bevel gear 432 is installed on the outer side of the lower end of the connecting cylinder 431 by key engagement. The mating mechanism 43 also includes a driven bevel gear 433 installed on the outer side of the opposite sides of multiple disturbance rods 42 by key engagement, and the driven bevel gear 433 and the driving bevel gear 432 mesh with each other. A sealing cylinder is rotatably sleeved on the outer side of the lower end of the connecting cylinder 431. The driven bevel gear 433 and the driving bevel gear 432 are both set inside the sealing cylinder, and the disturbance rods 42 and the sealing cylinder are rotatably connected, thereby preventing the flue gas from affecting the driven bevel gear 433 and the driving bevel gear 432.

[0050] The cooperating mechanism 43 is used to drive the disturbance rod 42 to revolve around the center line of the desulfurization tower 1 while rotating on its own axis. Specifically, when the disturbance rod 42 revolves around the center line of the desulfurization tower 1, the disturbance rod 42 drives the driven bevel gear 433 to revolve around the center line of the desulfurization tower 1. Under the action of the driven bevel gear 433 and the driving bevel gear 432, the driven bevel gear 433 drives the disturbance rod 42 to rotate on its own axis, thereby causing the disturbance rod 42 to revolve around the center line and rotate on its own axis at the same time.

[0051] See Figure 6 and Figure 7 The transmission mechanism 44 includes a transmission rod 441 rotatably mounted on the lower end of the rotating shaft 33. The upper end of the transmission rod 441 is configured as an elastic telescopic structure and rotatably passes through the lower end of the rotating shaft 33. A transmission circular plate 442 is fixedly mounted on the upper end of the transmission rod 441. Multiple circumferentially evenly arranged transmission blocks 443 are fixedly mounted on the upper end of the transmission circular plate 442. Transmission connecting rods 421 are fixedly mounted on opposite sides of multiple disturbance rods 42. The multiple transmission connecting rods 421 are rotatably connected to the transmission rod 441 on opposite sides.

[0052] See Figure 7 Two symmetrically arranged pressing and fitting columns 444 are fixedly installed on the outer side of the transmission circular plate 442, and multiple circumferentially evenly arranged pressing blocks 331 are fixedly installed on the inner side of the rotating shaft 33. The lower end of the pressing block 331 is set as an inclined surface for driving the pressing and fitting columns 444 to move downward.

[0053] See Figure 6 and Figure 7The angle adjustment mechanism 34 includes a bevel gear 341 mounted on opposite sides of the rotating shafts of multiple swirl blades 32 via a key connection. A bevel gear 342 is meshed on the lower side of the multiple bevel gears 341. A connecting column 343 is fixedly mounted on the lower end of the bevel gear 342. Multiple circumferentially evenly arranged guide rods 344 are fixedly mounted on the outer side of the connecting column 343. The opposite sides of the multiple guide rods 344 are slidably mounted in the arc grooves preset on the inner wall of the rotating shaft 33 via arc springs 345.

[0054] See Figure 7 A driven circular plate 346 is fixedly installed at the lower end of the connecting column 343. Multiple driven blocks 347 are evenly arranged in the circumference at the lower end of the driven circular plate 346. The driven blocks 347 are used to cooperate with the transmission block 443 to drive the driven circular plate 346 to rotate.

[0055] The transmission mechanism 44 is used in conjunction with the angle adjustment mechanism 34 to drive the swirl blade 32 to change its angle. Specifically, when the disturbance rod 42 revolves around the center line of the desulfurization tower 1, the disturbance rod 42 drives the transmission rod 441 to rotate through the transmission connecting rod 421. The transmission rod 441 drives the transmission block 443 to rotate through the transmission circular plate 442. The transmission block 443 and the driven block 347 cooperate to drive the bevel gear 342 to rotate through the driven circular plate 346 and the connecting column 343. At the same time, the connecting column 343 drives the guide rod 344 to rotate and compress the arc spring 345. The bevel gear 342 and the bevel gear 341 cooperate to drive the swirl blade 32 to rotate with its rotation axis as the reference, thereby changing the tilt angle of the swirl blade 32.

[0056] When the transmission plate 442 drives the lower pressing engagement column 444 to rotate to the corresponding position of the lower pressing block 331, the inclined surfaces of the lower pressing engagement column 444 and the lower pressing block 331 engage to drive the transmission plate 442 to move downward and compress the telescopic end of the transmission rod 441. This causes the transmission plate 442 to drive the transmission block 443 to move downward and separate from the driven block 347. Consequently, under the action of the arc spring 345, the guide rod 344 drives the bevel gear 342 to rotate to the initial position through the connecting column 343. This causes the bevel gear 342 and the bevel gear 341 to engage and drive the swirl blade 32 to rotate to the initial position with its rotation axis as the reference.

[0057] When the lower pressure engagement column 444 and the lower pressure block 331 separate, the transmission circular plate 442 returns to its initial position under the elastic structure of the transmission rod 441. This causes the transmission block 443 to engage with the driven block 347 again, driving the bevel gear 342 to rotate through the driven circular plate 346 and the connecting column 343. Since multiple lower pressure blocks 331 are provided, the swirl blades 32 can change their angle intermittently, thereby enhancing the turbulence of the flue gas and further promoting the full contact and reaction between the flue gas and the atomized slurry, thus improving the desulfurization efficiency of the flue gas.

[0058] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
