Description

Technical Field

[0001] The invention relates to the technical field of desulfurization equipment, and in particular to a desulfurization device for industrial waste gas. Background Art

[0002] Desulfurization refers to the process of removing sulfur from fuel before combustion and before flue gas emission. It is one of the important technical measures to prevent and control air pollution. There are generally three desulfurization methods: desulfurization before combustion, during combustion and after combustion. With the development of industry and the improvement of people's living standards, the thirst for energy is also increasing. SO2 in coal-fired flue gas has become the main cause of air pollution. Reducing SO2 pollution has become a top priority for today's atmospheric environmental governance. Many flue gas desulfurization processes have been widely used in industry, and they are also of great practical significance for the treatment of industrial waste gases such as tail gas from various boilers and incinerators. When treating industrial waste gas, desulfurization towers are usually required for desulfurization. Desulfurization towers generally include tower bodies, spray layers, demisters and circulation systems. The demister in the desulfurization tower is located at the top of the desulfurization tower. It removes water vapor carrying sulfate crystals in the gas after desulfurization by interception, inertial collision, etc. Therefore, it is necessary to regularly flush the demister to ensure the normal use of the demister.

[0003] A desulfurization tower demisting device is disclosed in a Chinese patent application document with publication number CN119158342A. The desulfurization tower demisting device includes a desulfurization tower, and a demisting device is installed at the lower end of the exhaust port of the desulfurization tower. The demisting device includes a circular mist catcher and a plurality of spraying devices. The outer coaxial fixed sleeve of the circular mist catcher is provided with an annular guide rail, and the plurality of spraying devices are evenly distributed in a circular array, and each spraying device is slidably installed on the annular guide rail through a slider at the lower end. The ends of the plurality of spraying devices close to each other are all provided with nozzles. When the circular mist catcher needs to be cleaned, the plurality of spraying devices can synchronously perform circular motion along the annular guide rail around the axis of the circular mist catcher, and the cleaning liquid is evenly sprayed on the circular mist catcher through the plurality of spraying devices.

[0004] However, the structural design of the above-mentioned related technology is as follows: when cleaning the demister in the desulfurization tower, although it can be cleaned by circular motion, the blades in the demister are usually corrugated. When the water flow flushes the demister, the area in the middle of the corrugated blade can only be cleaned by the flow of water, so that the flushing force on the middle area of ​​the blade is relatively small, and the demister cannot be flushed for a long time, which can easily lead to scaling in the middle area of ​​the blade, thereby causing the flue gas channel to become smaller, thereby affecting the flue gas emission efficiency, and subsequent shutdown for cleaning.

[0005] Therefore, a desulfurization device for industrial waste gas is proposed to solve the above-mentioned problems. Summary of the invention

[0006] The present invention provides a desulfurization device for industrial waste gas, aiming to solve the problem that the middle area of the corrugated blades in the demister in the related art is prone to fouling.

[0007] The desulfurization device for industrial waste gas of the present invention includes a desulfurization mechanism, a demisting mechanism is arranged in the desulfurization mechanism, and a scraping mechanism is arranged on the demisting mechanism; The demisting mechanism includes a mounting component and a plurality of demisting components. The mounting component is mounted on the desulfurization mechanism, and the plurality of demisting components are equidistantly distributed on the mounting component; The demisting component includes a fixing plate mounted on the mounting component, hinge seats respectively mounted on the top and bottom of the fixing plate, and a first movable plate and a second movable plate respectively hinged on the two hinge seats. Both the first movable plate and the second movable plate are inclined; The scraping mechanism includes a cleaning component slidably arranged on the outside of the fixing plate. The cleaning component includes two scraping plates. The two scraping plates are respectively slidably arranged on both sides of the fixing plate, and the two scraping plates can be transferred along the fixing plate to the outside of the first movable plate or the second movable plate so that the scraping plates can be rinsed.

[0008] During the use process, through the two scraping plates on both sides of the fixing plate, fog particles and slurry droplets can be isolated to prevent the fog particles and slurry droplets from adhering to the fixing plate to avoid fouling of the fixing plate. When cleaning the demisting mechanism, the first movable plate and the second movable plate are rinsed with water flow. After the first movable plate and the second movable plate are rinsed, the scraping plates will move up and down, so that the scraping plates are sequentially transferred to the first movable plate and the second movable plate. When the scraping plates are moved to the first movable plate and the second movable plate, the water flow can directly rinse the scraping plates, so that the scraping plates can be subjected to a large water flow impact, and when the scraping plates are transferred to the first movable plate or the second movable plate, the soft scale on the first movable plate and the second movable plate can be scraped off.

[0009] Preferably, the scraping mechanism further includes a lifting mechanism. The lifting mechanism includes a mounting ring. The mounting ring is located above the mounting component. The scraping plate is arranged on the mounting ring, and the mounting ring can reciprocally slide vertically in the desulfurization mechanism.

[0010] By the up and down movement of the mounting ring, the scraping plate can be driven to move up and down to drive the scraping plate to be transferred to the first movable plate or the second movable plate.

[0011] Preferably, the cleaning component further includes connecting plates. The number of the connecting plates is four. The four connecting plates are respectively mounted on both sides of the two scraping plates, and the top of the connecting plates is mounted on the mounting ring.

[0012] Preferably, torsion springs are arranged between the outermost first movable plate and the outermost second movable plate and the hinge seats connected thereto respectively.

[0013] Through the torsion springs on the outermost movable plate 1 and the outermost movable plate 2, the movable plate 1 and the movable plate 2 can automatically reset when the external force is removed.

[0014] Preferably, the mounting assembly includes a mounting base and multiple groups of chutes. The chutes are formed on the top of the mounting base, penetrate through the bottom of the mounting base and extend to the outside of the mounting base. The multiple groups of chutes correspond to the multiple fixing plates one by one, and the connecting plate is slidably connected to the chutes on the mounting base.

[0015] Preferably, each group of chutes has two in number, and the fixing plate is located between the two chutes.

[0016] Preferably, adjusting mechanisms are provided above and below the mounting base to adjust the tilting angles of the movable plate 1 and the movable plate 2.

[0017] Preferably, the adjusting mechanism includes a mounting frame, a hydraulic cylinder and an adjusting assembly. The mounting frame is installed on the inner wall of the desulfurization mechanism, the hydraulic cylinder is installed on the outside of the desulfurization mechanism, and the adjusting assembly is slidably arranged inside the mounting frame.

[0018] Preferably, the adjusting assembly includes a slide bar and multiple adjusting plates. The slide bar is slidably connected inside the mounting frame, the hydraulic cylinder is connected to one side of the slide bar, the multiple adjusting plates are equidistantly installed on the slide bar along the length direction of the slide bar, and the bottom of the adjusting plate penetrates through the bottom of the mounting frame and extends to the outside of the mounting frame.

[0019] Through the hydraulic cylinder, the slide bar can be driven to reciprocate inside the mounting frame to drive the adjusting plates on the slide bar to reciprocate.

[0020] Preferably, the multiple adjusting plates in the upper adjusting mechanism are respectively in contact with the multiple movable plates 1, and the multiple adjusting plates in the lower adjusting mechanism are respectively in contact with the multiple movable plates 2.

[0021] During the reciprocating sliding process of the adjusting plates, the adjusting plates located above can push the movable plate 1 to rotate, and the adjusting plates located below can push the movable plate 2 to rotate, so that the water flow can wash the movable plate 1 and the movable plate 2 more comprehensively, thereby further improving the cleaning effect.

[0022] Adopting the above technical solution, the beneficial effects of the present invention are as follows: During use, through the two scrapers on both sides of the fixing plate, fog particles and slurry droplets can be isolated, preventing the fog particles and slurry droplets from adhering to the fixing plate to avoid scaling of the fixing plate. When cleaning the demisting mechanism, water flow is used to wash the movable plate 1 and the movable plate 2. After the movable plate 1 and the movable plate 2 are washed, the scraper will move up and down, so that the scraper is sequentially transferred to the movable plate 1 and the movable plate 2. When the scraper moves onto the movable plate 1 and the movable plate 2, the water flow can directly wash the scraper, enabling the scraper to receive a large water flow impact to avoid scaling on the scraper, thereby reducing the number of shutdowns for maintenance. Moreover, when the scraper is transferred to the movable plate 1 or the movable plate 2, it can scrape off the soft scale on the movable plate 1 and the movable plate 2 to improve the overall cleaning effect of the demisting mechanism.

[0033] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, but should not be construed as limiting the present invention.

[0034] As Figures 1 to 9 As shown, the desulfurization device for industrial waste gas of the present invention includes a desulfurization mechanism 10, a demisting mechanism 20, an adjusting mechanism 30, and a scraping mechanism 40. The demisting mechanism 20 is arranged above the interior of the desulfurization mechanism 10 to remove the fog particles and slurry droplets entrained in the flue gas. There are two adjusting mechanisms 30, and the two adjusting mechanisms 30 are arranged oppositely, and the demisting mechanism 20 is located between the two adjusting mechanisms 30. The scraping mechanism 40 is arranged on the demisting mechanism 20 to protect the middle part of the demisting mechanism 20 and can scrape the fog particles, slurry droplets, and soft scale adsorbed on the demisting mechanism 20.

[0035] During use, the flue gas is introduced into the desulfurization mechanism 10, and after being desulfurized by the desulfurization mechanism 10, the flue gas passes through the demisting mechanism 20 and is discharged from the desulfurization mechanism 10. When it is necessary to clean the demisting mechanism 20, the upper and lower parts of the demisting mechanism 20 are driven to rotate by the adjusting mechanism 30 to adjust the contact surface between the water flow and the demisting mechanism 20. When the upper part of the demisting mechanism 20 is adjusted to the vertical state, the scraping mechanism 40 moves to the upper part of the demisting mechanism 20 so that the water flow can wash the scraping mechanism 40. When the lower part of the demisting mechanism 20 is adjusted to the vertical state, the scraping mechanism 40 moves down to the lower part of the demisting mechanism 20 so that the water flow can wash the scraping mechanism 40 again. During the movement of the scraping mechanism 40 on the demisting mechanism 20, the soft scale on the demisting mechanism 20 can be cleaned to prevent the soft scale from hardening due to being unable to be washed away.

[0036] As Figures 1 to 2As shown in the figure, the desulfurization mechanism 10 includes a tower body 11, a smoke exhaust cylinder 12, a smoke guiding cylinder 13 and a flushing assembly.

There are two flushing assemblies, which are symmetrically arranged, and the demisting mechanism 20 is located between the two flushing assemblies, and the demisting mechanism 20 can be flushed through the flushing assembly. A spraying assembly (not shown in the figure) is installed below the interior of the tower body 11 to spray slurry on the flue gas. It should be noted that the spraying assembly is a prior art, so the specific structure of the spraying assembly will not be described in detail here.

The other end of the water supply frame 14 is connected to an external water supply pump to supply water to the water supply frame 14. There are multiple spray nozzles 15, and the multiple spray nozzles 15 are evenly installed on the water supply frame 14.

[0038] When the external water pump supplies water to the water supply frame 14, the water in the water supply frame 14 is sprayed onto the demisting mechanism 20 through the spray nozzles 15 to flush the demisting mechanism 20.

The outer peripheral surface of the mounting base 211 is circular and is installed on the inner wall of the tower body 11. The inner side of the mounting base 211 is stepped to install the demisting assembly 22. The sliding groove 212 is opened at the top of the mounting base 211, and the sliding groove 212 penetrates through the bottom of the mounting base 211 and extends to the outside of the mounting base 211. There are multiple groups of sliding grooves 212, and the multiple groups of sliding grooves 212 correspond to the multiple demisting assemblies 22 one by one. Each group of sliding grooves 212 has two, and the demisting assembly 22 is located between the two sliding grooves 212. The scraping mechanism 40 is slidably connected in the sliding groove 212 so that the scraping mechanism 40 can slide up and down in the sliding groove 212.

[0041] As Figures 3 to 5As shown in the figure, the demisting assembly 22 includes a fixed plate 221, a hinge seat 222, a first movable plate 223, and a second movable plate 224. The fixed plate 221 is installed on the inner wall of the mounting seat 211. There are two hinge seats 222, and the two hinge seats 222 are respectively installed at the top and the bottom of the fixed plate 221. Slots adapted to the hinge seats 222 are formed on both the first movable plate 223 and the second movable plate 224. The first movable plate 223 is located at the top of the mounting seat 211, and the first movable plate 223 is hinged to the hinge seat 222 at the top of the fixed plate 221 through a pin shaft. The second movable plate 224 is located at the bottom of the mounting seat 211, and the first movable plate 223 is hinged to the hinge seat 222 at the bottom of the fixed plate 221 through a pin shaft. Torque springs (not shown in the figure) are provided between the outermost first movable plate 223 and the outermost second movable plate 224 and their respective connected hinge seats 222, so that the outermost first movable plate 223 and the outermost second movable plate 224 can automatically reset. In the initial state, both the first movable plate 223 and the second movable plate 224 are inclined to intercept the fog particles and slurry droplets entrained in the flue gas.

[0042] As Figure 2 and Figures 5 to 6 shown, the adjusting mechanism 30 includes a mounting frame 31, a hydraulic cylinder 32, and an adjusting assembly. The mounting frame 31 is installed on the inner wall of the tower body 11, and the mounting frame 31 is located between the two water supply frames 14. The hydraulic cylinder 32 is installed on the outside of the tower body 11, and the adjusting assembly is slidably connected to the inside of the mounting frame 31.

[0043] As Figure 2 and Figures 4 to 6 shown, the adjusting assembly includes a slide bar 33, an adjusting plate 34, and a guide rod 35. The slide bar 33 is slidably connected to the inside of the mounting frame 31. The movable end of the hydraulic cylinder 32 penetrates through one side of the mounting frame 31 and is connected to one side of the slide bar 33. One end of the guide rod 35 is installed on one side of the inner wall of the mounting frame 31, and the other end of the guide rod 35 penetrates through the other side of the slide bar 33 and extends into the inside of the slide bar 33. A hole for the guide rod 35 to slide is formed on the other side of the slide bar 33. There are multiple adjusting plates 34, and the multiple adjusting plates 34 are equidistantly installed at the bottom of the slide bar 33 along the length direction of the slide bar 33. The bottom of the adjusting plate 34 penetrates through the bottom of the mounting frame 31 and extends to the outside of the mounting frame 31. Slots for the adjusting plate 34 to slide are formed at the bottom of the mounting frame 31.

[0044] The multiple adjusting plates 34 in the adjusting mechanism 30 located above the first movable plate 223 are respectively in contact with the multiple first movable plates 223 to push the first movable plate 223 to rotate. The multiple adjusting plates 34 in the adjusting mechanism 30 located below the second movable plate 224 are respectively in contact with the multiple second movable plates 224 to push the second movable plate 224 to rotate.

[0045] When it is necessary to clean the demisting mechanism 20, the water supply frame 14 sprays water through the nozzles 15 onto the first movable plate 223 and the second movable plate 224 respectively to wash the fog particles and slurry droplets on the first movable plate 223 and the second movable plate 224. During the washing process, first start the hydraulic cylinder 32 located above. At this time, the hydraulic cylinder 32 located above drives the upper slide bar 33 to slide in the mounting frame 31. During the sliding process of the upper slide bar 33, the first movable plate 223 is pushed to rotate on the hinge seat 222 through the upper adjusting plate 34 to adjust the inclination direction of the first movable plate 223, so that the upper nozzle 15 can fully wash the first movable plate 223. After the first movable plate 223 is washed, the hydraulic cylinder 32 located above drives the adjusting plate 34 on the slide bar 33 to reset, so as to drive the first movable plate 223 to reset.

[0046] At this time, start the hydraulic cylinder 32 located below. The hydraulic cylinder 32 located below drives the lower slide bar 33 to slide in the mounting frame 31. During the sliding process of the lower slide bar 33, the second movable plate 224 is pushed to rotate on the hinge seat 222 through the lower adjusting plate 34 to adjust the inclination direction of the second movable plate 224, so that the lower nozzle 15 can fully wash the second movable plate 224. After the second movable plate 224 is washed, the hydraulic cylinder 32 located below drives the adjusting plate 34 on the slide bar 33 to reset, so as to drive the second movable plate 224 to reset.

[0047] As Figure 2 、 Figure 4 and Figure 7 As shown in

[0048] The scraping mechanism 40 includes a lifting mechanism and a cleaning component 42. The lifting mechanism is arranged at the top of the mounting seat 211. The number of the cleaning components 42 is multiple, and multiple cleaning components 42 are all installed on the lifting mechanism. Multiple cleaning components 42 are respectively located outside multiple fixing plates 221 to isolate the fixing plates 221 and prevent fog particles and slurry droplets from sticking to the fixing plates 221.

[0049] As Figure 2 、 Figure 5 and Figures 7 to 8As shown in the figure, the lifting mechanism includes a mounting ring 41, a lead screw 43, a motor 44, and a slide bar 45. The mounting ring 41 is located above the mounting base 211. A plurality of cleaning components 42 are all mounted inside the mounting ring 41, and the water supply frame 14 and the mounting frame 31 are both located below the mounting ring 41. The lead screw 43 is threadedly connected to one side of the top end of the mounting ring 41. The bottom end of the lead screw 43 penetrates through the mounting ring 41 and is rotatably connected to one side of the top end of the mounting base 211. The motor 44 is mounted on the outer side of the smoke guide cylinder 13, and the output shaft of the motor 44 is connected to the top end of the lead screw 43. The slide bar 45 is slidably connected to the other side of the top end of the mounting ring 41. The bottom end of the slide bar 45 penetrates through the mounting ring 41 and is mounted on the other side of the top end of the mounting base 211.

[0050] When it is necessary to drive the cleaning component 42 to move up and down, the motor 44 drives the mounting ring 41 to move up and down through the lead screw 43. During the up and down movement of the mounting ring 41, it can drive the cleaning component 42 to move up and down to adjust the position of the cleaning component 42.

[0051] As Figures 7 to 9 shown in the figure, the cleaning component 42 includes a scraper 421 and a connecting plate 422. There are two scrapers 421, and the two scrapers 421 are respectively located on both sides of the fixing plate 221. There are four connecting plates 422, and the four connecting plates 422 are respectively mounted on both sides of the two scrapers 421. The connecting plate 422 is in an L shape. The top of the connecting plate 422 is mounted inside the mounting ring 41, and the connecting plate 422 is slidably connected to the chute 212 on the mounting base 211.

[0052] When the mounting ring 41 moves upward, the mounting ring 41 can drive the scraper 421 to move upward through the connecting plate 422 and make the scraper 421 move along the movable plate one 223, so that the scraper 421 can scrape off the soft scale on the movable plate one 223 during the upward movement.

[0053] When the mounting ring 41 moves downward, the mounting ring 41 can drive the scraper 421 to move downward through the connecting plate 422 and make the scraper 421 move along the movable plate two 224, so that the scraper 421 can scrape off the soft scale on the movable plate two 224 during the downward movement.

[0054] Working principle: When it is necessary to clean the demisting mechanism 20, water is supplied to the water supply frame 14 through an external water pump. At this time, the water in the water supply frame 14 is sprayed onto the movable plate one 223 and the movable plate two 224 through the nozzle 15 to wash the movable plate one 223 and the movable plate two 224. During the washing process, two hydraulic cylinders 32 are started successively. At this time, the two hydraulic cylinders 32 drive the adjusting plate 34 to reciprocate through the slide bars 33 thereon.

[0055] During the movement of the upper adjusting plate 34, the first movable plate 223 is pushed to rotate on the hinge seat 222, so that the nozzle 15 can thoroughly wash the first movable plate 223. During the movement of the lower adjusting plate 34, the second movable plate 224 is pushed to rotate on the hinge seat 222, so that the nozzle 15 can thoroughly wash the second movable plate 224.

[0056] When the first movable plate 223 rotates to the vertical state during the reset process, the motor 44 drives the mounting ring 41 to move upward through the lead screw 43. During the upward movement of the mounting ring 41, the scraper 421 is driven to move upward through the connecting plate 422 to scrape the soft scale on the first movable plate 223. At this time, the nozzle 15 can wash the scraper 421 to prevent fog particles and slurry drops from adhering to the scraper 421. After the scraper 421 cleans the first movable plate 223, the motor 44 drives the scraper 421 to reset through the mounting ring 41 on the lead screw 43.

[0057] When the second movable plate 224 rotates to the vertical state during the reset process, the motor 44 drives the mounting ring 41 to move downward through the lead screw 43. During the downward movement of the mounting ring 41, the scraper 421 is driven to move downward through the connecting plate 422 to scrape the soft scale on the second movable plate 224. After the scraper 421 cleans the second movable plate 224, the motor 44 drives the scraper 421 to reset through the mounting ring 41 on the lead screw 43 to continue to protect the fixed plate 221.
