Description

Technical Field

[0001] The present invention relates to the technical field of flue gas desulfurization, and specifically to a desulfurization device for sintering flue gas based on lepidolite. Background Art

[0002] Lepidolite sintering is a process for treating lepidolite ore. During the lepidolite sintering process, a large amount of flue gas containing pollutants such as sulfur dioxide is generated. If these flue gases are not effectively desulfurized and directly discharged, it will cause serious environmental pollution and trigger environmental problems such as acid rain. Therefore, it is necessary to desulfurize the flue gas generated after lepidolite sintering.

[0003] Currently, wet desulfurization is often used to desulfurize flue gas. The flue gas is introduced into a desulfurization tower, and the desulfurization slurry is sprayed in an atomized form through a spraying device. At the same time, a swirl plate is arranged in the desulfurization tower, so that the flue gas contacts and reacts with the atomized slurry in a spiral rising manner to enhance the gas-liquid contact and achieve the desulfurization treatment of the flue gas.

[0004] The following problems may exist when desulfurizing flue gas currently: 1. Since the swirl blades of the swirl 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. There may be particulate impurities such as ore dust and solid products after reaction in the flue gas. When the flue gas passes through the swirl plate, the particulate impurities in the flue gas may scour the swirl plate, causing wear of the swirl plate and thus affecting the service life of the swirl plate.

Detailed implementation manners

[0028] The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as a limitation to the present invention. For those not specified in the embodiments regarding specific technologies or conditions, they shall be carried out according to the technologies or conditions described in the literature in this field or according to the product manuals.

[0029] Refer to Figure 1 and Figure 2 , a desulfurization device for lithium mica sintering flue gas, comprising a desulfurization tower 1, a spray unit 2 is installed in the desulfurization tower 1, a flue gas guiding unit 3 is installed below the spray unit 2 in the desulfurization tower 1, a disturbance unit 4 is jointly installed between the lower side of the flue gas guiding unit 3 and the desulfurization tower 1, and an impurity removal unit 5 is installed below the disturbance unit 4 in the desulfurization tower 1.

[0030] It should be noted that a flue gas inlet cylinder is installed at the lower left side of the desulfurization tower 1 in the present invention, a flue gas outlet cylinder is installed at the upper end of the desulfurization tower 1, a slurry inlet pipe and a slurry discharge pipe are respectively installed on the left and right sides of the lower part of the desulfurization tower 1. Through the slurry inlet pipe, desulfurization slurry can be introduced into the desulfurization tower 1, and the spray unit 2 is communicated with the desulfurization slurry in the desulfurization tower 1, so that the spray unit 2 can spray the desulfurization slurry downward in an atomized form, enabling the rising flue gas to contact and react with the atomized flue gas, and the desulfurization products can be discharged from the slurry discharge pipe.

[0031] The present invention is used for desulfurizing the flue gas generated during lithium mica sintering, and the present invention can first filter the particulate impurities in the flue gas, thereby preventing the particulate impurities mixed in the flue gas from scouring and wearing the flue gas guiding unit 3, ensuring the service life of the flue gas guiding unit 3. At the same time, the present invention can also disturb the flue gas, so that the flue gas can be evenly distributed, enabling the flue gas to fully contact and react with the atomized slurry, and increasing the desulfurization effect on the flue gas.

[0032] Specifically, first, the flue gas is introduced into the desulfurization tower 1. The flue gas rises from the bottom of the desulfurization tower 1. The impurity removal unit 5 can first remove the particulate impurities in the flue gas, causing the particulate impurities mixed in the flue gas to fall to the bottom of the desulfurization tower 1. Then, the desulfurized flue gas passes through the disturbance unit 4. By starting the disturbance unit 4 to continuously disturb the flue gas, the flue gas can uniformly pass through the flue gas guiding unit 3 under the action of the disturbance unit 4, and the flue gas spirally rises under the action of the flue gas guiding unit 3. At the same time, the spraying unit 2 is started to atomize and spray the slurry, so that the spirally rising flue gas and the atomized slurry fully contact and react to achieve the desulfurization of the flue gas. The particulate impurities generated after the atomized slurry and the flue gas react can fall downward onto the impurity removal unit 5, and 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 the desulfurization tower 1.

[0033] Refer to Figure 2 、 Figure 3 and Figure 5 The impurity removal unit 5 includes an impurity removal plate 51 with a spherical upper end distributed in the desulfurization tower 1. A plurality of impurity removal holes are formed in the impurity removal plate 51, and the upper ends of the impurity removal holes are inclined toward the middle of the impurity removal plate 51. The impurity removal plate 51 is connected to the desulfurization tower 1 through an intermittent slag discharging mechanism 52.

[0034] The impurity removal unit 5 is used to remove the particulate impurities in the flue gas; specifically, when the flue gas rises, the flue gas passes through the impurity removal holes of the impurity removal plate 51 and rises above the impurity removal plate 51. Since the upper ends of the impurity removal holes are inclined toward the middle of the impurity removal plate 51, the flue gas moves along the inclined direction of the slag discharging holes. The inner wall of the impurity removal holes can intercept the particulate impurities in the flue gas, and the inclined impurity removal holes are conducive to the particulate impurities in the flue gas sliding downward along the inclined structure of the impurity removal holes under the action of gravity, preventing the particulate impurities in the flue gas from blocking the impurity removal holes.

[0035] After the atomized slurry and the flue gas fully contact and react, the generated particulate impurities can fall onto the upper end of the impurity removal plate 51 and slide along the spherical surface at the upper end of the impurity removal plate 51 to the intermittent slag discharging mechanism 52, so that the intermittent slag discharging mechanism 52 can intermittently discharge the particulate impurities on the impurity removal plate 51 and fall to the lower side inside the desulfurization tower 1.

[0036] Refer to Figures 2 - 4 The disturbance unit 4 includes an annular electric slider assembly 41 installed in the desulfurization tower 1. A plurality of disturbance rods 42 are circumferentially and uniformly arranged in the annular electric slider assembly 41. A plurality of groups of disturbance enhancement rod groups 45 are fixedly installed on the outer side of the disturbance rods 42 and are uniformly arranged along their lengths. A cooperation mechanism 43 is jointly installed between the opposite sides of the plurality of disturbance rods 42 and the rotating shaft 33. The cooperation mechanism 43 is used to make the disturbance rods 42 revolve and rotate simultaneously.

[0037] The disturbance enhancement rod group 45 includes a plurality of disturbance enhancement rods that are fixedly installed outside the disturbance rod 42 and are circumferentially and uniformly arranged.

[0038] It should be noted that the annular electric slider assembly 41 in the present invention includes a transmission ring, an annular slide rail, and an arc-shaped electric slider. The transmission ring is rotatably installed in the desulfurization tower 1. The outer side of the transmission ring is fixedly connected to a plurality of arc-shaped electric sliders that are circumferentially and uniformly arranged. A plurality of 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 a plurality of arc-shaped electric sliders to slide along the annular slide rail, the plurality of arc-shaped electric sliders drive the transmission ring to rotate with the center line of the desulfurization tower 1 as the reference.

[0039] The disturbance unit 4 is used to disturb the flue gas. Specifically, when starting the annular electric slider assembly 41 to drive the disturbance rod 42 to revolve with the center line of the desulfurization tower 1 as the reference, 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, so that the flue gas can evenly rise to the corresponding position of the flue gas guiding unit 3. At the same time, under the action of the matching mechanism 43, the disturbance rod 42 can rotate around its center line, so that the disturbance rod 42 drives the disturbance enhancement rod to rotate, increasing the disturbance effect on the flue gas and further ensuring the even distribution of the flue gas.

[0040] Refer to Figure 2 and Figure 3 , the intermittent slag discharging mechanism 52 includes a slag discharging plate 521 fixedly sleeved outside the impurity removing plate 51. The outer side of the slag discharging plate 521 is slidably connected to the desulfurization tower 1 up and down through a plurality of circumferentially and uniformly arranged fixing plates. A return spring 522 is connected between the fixing plate and the desulfurization tower 1. A plurality of circumferentially and uniformly arranged slag discharging holes are formed on the slag discharging plate 521.

[0041] Refer to Figures 2 - 4 , a plurality of circumferentially and uniformly arranged L-shaped matching plates 411 are fixedly installed on the annular electric slider assembly 41 and below the disturbance rod 42. A plurality of circumferentially and uniformly arranged lower pressing plates 525 are fixedly installed on the upper side of the slag discharging plate 521. The upper end of the lower pressing plate 525 is provided with an inclined surface for cooperating with the matching plate 411.

[0042] Refer to Figure 5 , a blocking plate 523 is rotatably installed at the lower end of the slag discharging plate 521. A plurality of circumferentially and uniformly arranged phase adjustment holes are formed on the blocking plate 523, and the phase adjustment holes are initially staggered with the slag discharging holes. A plurality of circumferentially and uniformly arranged matching blocks 524 are fixedly installed on the outer side of the blocking plate 523. Matching grooves 11 are formed on the inner wall of the desulfurization tower 1 corresponding to the positions of the matching blocks 524, and the matching blocks 524 are all slidably installed in the matching grooves 11. The matching grooves 11 are arranged as an inclined structure for cooperating with the matching blocks 524 to drive the blocking plate 523 to rotate.

[0043] The intermittent slag discharging mechanism 52 is used to intermittently discharge the granular impurities on the impurity removal plate 51; specifically, when the atomized slurry and the flue gas are in full contact and react, the generated granular impurities can fall onto the upper end of the impurity removal plate 51 and slide down along the spherical surface at the upper end of the impurity removal plate 51 to the slag discharging plate 521. Initially, the phase adjustment holes of the blocking plate 523 and the slag discharging holes of the slag discharging plate 521 are arranged in an alternating manner, so that the blocking plate 523 blocks the slag discharging holes of the slag discharging plate 521. As a result, the granular impurities will not fall downward at this time, and at the same time, the flue gas cannot rise above the impurity removal plate 51 through the phase adjustment holes of the blocking plate 523 and the slag discharging holes of the slag discharging plate 521, thus ensuring that the flue gas can rise above the impurity removal plate 51 through the slag discharging holes of the impurity removal plate 51.

[0044] When the annular electric slider assembly 41 is started to drive the disturbing rod 42 to revolve around the center line of the desulfurization tower 1 as a reference, 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 pressing plate 525, the mating plate 411 and the inclined surface of the lower pressing plate 525 cooperate to drive the slag discharging plate 521 and the impurity removal plate 51 to move downward and compress the return spring 522 through the fixing plate. When the mating plate 411 and the lower pressing plate 525 are separated, the slag discharging plate 521 and the impurity removal plate 51 bounce back to the initial position under the action of the return spring 522, thereby realizing the up-and-down jitter of the impurity removal plate 51, ensuring that the granular impurities on the impurity removal plate 51 can slide down along the spherical surface at the upper end of the impurity removal plate 51 to the slag discharging plate 521, and at the same time preventing the granular impurities from blocking the impurity removal holes of the impurity removal plate 51.

[0045] When the slag discharging plate 521 moves downward, the slag discharging plate 521 drives the blocking plate 523 to move downward. At the same time, the mating block 524 and the inclined structure of the mating groove 11 cooperate to drive the blocking plate 523 to rotate, so that the phase adjustment holes of the blocking plate 523 and the slag discharging holes of the slag discharging plate 521 are aligned, and thus the impurities on the slag discharging plate 521 at this time can fall to the lower side inside the desulfurization tower 1.

[0046] Refer to Figure 2 、 Figure 3 and Figure 6 Referring to

[0047] Refer to Figure 6 As shown in

[0048] The flue gas guiding unit 3 is used to make the flue gas rise in a spiral manner; specifically, when the flue gas rises through the swirl vanes 32, the flue gas spirally rises under the action of the obliquely arranged swirl vanes 32, thereby ensuring sufficient contact and reaction between the atomized slurry and the flue gas. At the same time, under the combined action of the transmission mechanism 44 and the angle adjustment mechanism 34, the swirl vanes 32 are driven to change their angles periodically, so as to enhance the turbulence degree of the flue gas, further promote the sufficient contact and reaction between the flue gas and the atomized slurry, and improve the desulfurization efficiency of the flue gas.

[0049] Refer to Figure 3 and Figure 6 For the cooperating mechanism 43, it includes a connecting cylinder 431 fixedly installed at the lower end of the rotating shaft 33. An active bevel gear 432 is installed on the outer side of the lower end of the connecting cylinder 431 by means of key fitting. The cooperating mechanism 43 further includes a driven bevel gear 433 installed on the outer sides of the opposite sides of a plurality of disturbing rods 42 by means of key fitting, and the driven bevel gear 433 meshes with the active bevel gear 432; wherein, a sealing cylinder is rotatably sleeved on the outer side of the lower end of the connecting cylinder 431. Both the driven bevel gear 433 and the active bevel gear 432 are arranged inside the sealing cylinder, and the disturbing rod 42 is rotatably connected to the sealing cylinder, thereby preventing the flue gas from affecting the driven bevel gear 433 and the active bevel gear 432.

[0050] The cooperating mechanism 43 is used to drive the disturbing rod 42 to revolve and rotate simultaneously; specifically, when the disturbing rod 42 revolves with the center line of the desulfurization tower 1 as the reference, the disturbing rod 42 drives the driven bevel gear 433 to revolve with the center line of the desulfurization tower 1 as the reference, and under the action of the driven bevel gear 433 and the active bevel gear 432, the driven bevel gear 433 drives the disturbing rod 42 to rotate, so that the disturbing rod 42 revolves and rotates simultaneously.

[0051] Refer to Figure 6 and Figure 7 For the transmission mechanism 44, it includes a transmission rod 441 rotatably installed at the lower end of the rotating shaft 33. The upper end of the transmission rod 441 is provided with an elastic telescopic structure and rotatably penetrates through the lower end of the rotating shaft 33. A transmission circular plate 442 is fixedly installed at the upper end of the transmission rod 441. A plurality of transmission blocks 443 are fixedly installed on the upper end of the transmission circular plate 442 and are circumferentially and evenly arranged. Transmission connecting rods 421 are fixedly installed on the opposite sides of a plurality of disturbing rods 42, and the opposite sides of a plurality of transmission connecting rods 421 are all rotatably connected to the transmission rod 441.

[0052] Refer to Figure 7 On the outer side of the transmission circular plate 442, two symmetrically arranged downward pressing and cooperating columns 444 are fixedly installed. Inside the rotating shaft 33, a plurality of downward pressing blocks 331 are fixedly installed and are circumferentially and evenly arranged. The lower end of the downward pressing block 331 is provided with an inclined surface for driving the downward pressing and cooperating column 444 to move downward.

[0053] Refer to Figure 6 and Figure 7, the angle adjustment mechanism 34 includes a first bevel gear 341 installed on the opposite sides of the rotating shafts of multiple swirl vanes 32 by key fitting. A second bevel gear 342 is meshed and installed under multiple first bevel gears 341. A connecting column 343 is fixedly installed at the lower end of the second bevel gear 342. Multiple guide rods 344 arranged circumferentially and uniformly are fixedly installed on the outer side of the connecting column 343. On the opposite sides of multiple guide rods 344, they are all slidably installed in arc-shaped grooves preset on the inner wall of the rotating shaft 33 through arc-shaped springs 345.

[0054] Refer to Figure 7 , a driven circular plate 346 is fixedly installed at the lower end of the connecting column 343. Multiple driven blocks 347 arranged circumferentially and uniformly are fixedly installed at the lower end of the driven circular plate 346. The driven blocks 347 are used to cooperate with the driving blocks 443 to drive the driven circular plate 346 to rotate.

[0055] The transmission mechanism 44 is used to cooperate with the angle adjustment mechanism 34 to drive the angle change of the swirl vanes 32; specifically, when the disturbance rod 42 revolves with the center line of the desulfurization tower 1 as the reference, the disturbance rod 42 drives the transmission rod 441 to rotate through the transmission connecting rod 421. The transmission rod 441 drives the driving block 443 to rotate through the transmission circular plate 442, so that the driving block 443 and the driven block 347 cooperate to drive the second 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 rods 344 to rotate and compress the arc-shaped springs 345, and the second bevel gear 342 and the first bevel gear 341 cooperate to drive the swirl vanes 32 to rotate with its rotating shaft as the reference, thereby changing the inclination angle of the swirl vanes 32.

[0056] When the pressing cooperation column 444 drives the lower pressing block 331 to rotate to the corresponding position of the lower pressing block 331, the pressing cooperation column 444 and the inclined surface of the lower pressing block 331 cooperate to drive the transmission circular plate 442 to move downward and compress the telescopic end of the transmission rod 441, so that the transmission circular plate 442 drives the driving block 443 to move downward and separate from the driven block 347. Furthermore, at this time, the guide rod 344 drives the second bevel gear 342 to rotate to the initial position through the connecting column 343 under the action of the arc-shaped spring 345, so that the second bevel gear 342 and the first bevel gear 341 cooperate to drive the swirl vanes 32 to rotate to the initial position with its rotating shaft as the reference.

[0057] When the pressing cooperation column 444 separates from the lower pressing block 331, the transmission circular plate 442 returns upward to the initial position under the action of the elastic structure of the transmission rod 441. Furthermore, the driving block 443 and the driven block 347 cooperate again to drive the second bevel gear 342 to rotate through the driven circular plate 346 and the connecting column 343. And there are multiple lower pressing blocks 331, so that the swirl vanes 32 can change the angle intermittently, thereby enhancing the turbulence degree of the flue gas, further promoting the full contact reaction between the flue gas and the atomized slurry, and improving the desulfurization efficiency of the flue gas.
