Description

Technical Field

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

[0002] In industrial production, the emission of sulfur-containing waste gas is a major contributor to air pollution. Sulfur compounds such as sulfur dioxide and hydrogen sulfide not only cause environmental problems like acid rain but also pose a serious threat to human health and the ecological balance. Therefore, efficient desulfurization technology has become a key component of industrial waste gas treatment.

[0003] At present, the desulfurization technologies commonly used in industry mainly include dry desulfurization, wet desulfurization and semi-dry desulfurization. Dry desulfurization technology, such as activated carbon adsorption, has the advantages of simple process flow and no wastewater generation, but it has problems such as limited adsorption capacity, difficulty in regenerating adsorption materials, and low desulfurization efficiency. It is difficult to meet the needs of deep treatment of high-concentration sulfur-containing waste gas. Wet desulfurization technology is widely used. For example, the limestone-gypsum method removes sulfides by reacting alkaline absorbents with sulfur-containing gases. The desulfurization efficiency is high, but there are problems such as severe equipment corrosion, easy generation of large amounts of desulfurization wastewater, high operating costs, and difficulty in subsequent wastewater treatment. Semi-dry desulfurization combines some of the advantages of dry and wet methods, but it still has shortcomings in desulfurization efficiency and system stability, and is prone to scaling and clogging, affecting the continuous and stable operation of the device.

[0004] The desulfurization tower and desulfurization device presented in Patent 202311142500.4 divide the desulfurization space into multi-stage spray chambers by arranging multiple groups of spray components in the desulfurization space, and perform multi-stage spray desulfurization on the flue gas. At the same time, the flue gas entering the spray chambers at each level is evenly distributed with an air guide plate, which promotes full contact between the flue gas and the spray liquid, thereby improving the desulfurization effect. This embodies the concept of multi-stage treatment and optimized gas-liquid contact. However, the existing technology, including the above-mentioned patents, still has many limitations. On the one hand, when treating sulfur-containing gases, there is a lack of efficient means for the early separation of particulate sulfur-containing substances and impurities in the gas, which causes the nozzles in the subsequent spray system to be easily clogged by impurities, and the adsorption materials in the adsorption desulfurization system to be easily contaminated, which not only reduces the stability of the equipment operation, but also shortens the service life of the equipment and increases maintenance costs.

[0005] Therefore, it is necessary to provide a desulfurization device to solve the above technical problems. Summary of the Invention

[0006] The object of the present invention is to provide a desulfurization device to solve the existing problems in the above background technology.

[0009] A dual centrifugal separation system, a spray desulfurization system and an adsorption desulfurization system are distributed in the central tower from bottom to top. The dual centrifugal separation system includes an inner centrifugal cylinder, which is located in the central tower. An air intake pipe is connected to the outer wall of the centrifugal cylinder. The air intake pipe passes through the central tower and extends outward. The air intake pipe is arranged along the tangential direction of the side wall of the centrifugal cylinder. An inner spiral channel is provided in the inner centrifugal cylinder through a plurality of spirally arranged inner spiral plates. An outer spiral channel is provided on the inner wall of the central tower through a plurality of spirally arranged outer spiral plates, and the outer spiral channel is arranged between the central tower and the inner centrifugal cylinder. A guide hole is provided on the inner centrifugal cylinder, and the guide holes are distributed along the axial direction of the inner centrifugal cylinder and are evenly arranged circumferentially. The guide hole is an inclined circular hole. It is worth noting that the guide hole is arranged above the inner spiral plate.

[0010] As a further solution of the present invention, the spray desulfurization system is divided into a coarse spray layer, a fine spray layer and a buffer spray layer from bottom to top. The coarse spray layer, the fine spray layer and the buffer spray layer are all horizontally arranged grid structures, and are respectively equipped with nozzles of different types and densities.

[0011] As a further solution of the present invention, the adsorption and shedding system includes an adsorption plate, which is arranged on the inner wall of the central tower. The interior of the adsorption plate is filled with activated carbon, and the activated carbon particles are evenly laid.

[0012] As a further solution of the present invention, the inner spiral plate is installed on the inner wall of the central tower through an installation assembly, a sealing box is installed on the outer wall of the central tower, and a transmission hole is opened on the central tower to achieve communication with the interior of the sealing box. The sealing box is provided with a drive motor, and the drive motor drives the installation assembly and the inner spiral plate to rotate through the transmission assembly.

[0013] As a further solution of the present invention, the mounting assembly includes a fixed ring and an extended vertical plate, and the fixed ring is fixed on the inner wall of the central tower, the extended vertical plate is arranged at the lower end of the inner spiral plate, and the lower ends of multiple extended vertical plates are commonly provided with a connecting ring, the connecting ring is located in the inner centrifugal cylinder, the lower end of the connecting ring is connected to a driving ring through an extension frame, the upper end of the driving ring is provided with a limiting ring, the lower end surface of the fixed ring is provided with an annular limiting groove, and the limiting ring is movably connected in the annular limiting groove.

[0014] As a further solution of the present invention, the transmission assembly includes a gear ring, and the gear ring is compounded on the limiting ring. The output end of the drive motor is equipped with a drive gear, and the drive gear is meshed with the gear ring through a transmission hole.

[0017] In the present invention, the inner centrifugal cylinder and the air inlet pipe are arranged along the tangential direction of the side wall of the inner centrifugal cylinder, and the sulfur-containing gas cuts into the inner spiral channel at high speed. The channel is formed by a spiral arrangement of multiple inner spiral plates. During the rotation of the gas in the channel, the particulate sulfur-containing substances and impurities are acted upon by centrifugal force and move rapidly toward the wall of the inner centrifugal cylinder to achieve preliminary separation. After the sulfur-containing gas completes the preliminary centrifugal separation in the inner spiral channel, some of the gas that still contains a small amount of residual impurities will enter the outer spiral channel through the guide hole. The gas forms a spiral motion again in the outer spiral channel, generating a secondary centrifugal force to further capture and separate the residual particulate impurities. This process performs a secondary screening of the gas, greatly reducing the particle content entering the subsequent spray desulfurization system and adsorption desulfurization system, reducing the risk of nozzle clogging and contamination of the adsorption material, and effectively improving the overall desulfurization efficiency. At the same time, the secondary centrifugal separation can also reduce the wear of subsequent equipment components by particulate matter in the gas, thereby extending the service life of the equipment.

DETAILED DESCRIPTION

[0031] Example 1

[0032] like Figure 1-Figure 2As shown, a desulfurization device includes a tower body 1, which is divided into a collecting hopper 101, a central tower 102 and a gas collecting hopper 103 from bottom to top. The gas collecting hopper 103 is a cone with a narrow top and a wide bottom. The gas collecting hopper 103 is connected to an air outlet pipe 2. The collecting hopper 101 is an inverted cone with a wide top and a narrow bottom. The principle of gravity is used to make the separated solid particles and liquids naturally converge to the bottom, which is convenient for centralized collection and discharge. The lower end of the collecting hopper 101 is connected to a discharge pipe 3 and a liquid discharge pipe 4. The end of the discharge pipe 3 away from the collecting hopper 101 is connected to a screw feeder.

[0033] The collecting hopper 101 collects solid particles from the centrifugal separation stage and sulfur-containing waste liquid from the spray desulfurization stage. Since the collecting hopper 101 is an inverted cone with a wide top and a narrow bottom, it is convenient for the collection of solids and liquids. The solid particles enter the screw feeder through the discharge pipe 3 and are transported to the designated location for treatment; the sulfur-containing waste liquid is discharged through the liquid outlet pipe 4 for subsequent waste liquid treatment.

[0034] A dual centrifugal separation system, a spray desulfurization system and an adsorption desulfurization system are distributed in the central tower 102 from bottom to top. The dual centrifugal separation system includes an inner centrifugal cylinder 5, which is located in the central tower 102. An air intake pipe 6 is connected to the outer wall of the centrifugal cylinder 5. The air intake pipe 6 passes through the central tower 102 and extends outward. The air intake pipe 6 is arranged along the tangential direction of the side wall of the centrifugal cylinder 5. An inner spiral channel is provided in the inner centrifugal cylinder 5 through a plurality of spirally arranged inner spiral plates 7. An outer spiral channel is provided on the inner wall of the central tower 102 through a plurality of spirally arranged outer spiral plates 8, and the outer spiral channel is arranged between the central tower 102 and the inner centrifugal cylinder 5. A guide hole 9 is provided on the inner centrifugal cylinder 5, and the guide holes 9 are distributed axially along the inner centrifugal cylinder 5 and evenly arranged circumferentially. The guide hole 9 is an inclined circular hole. It is worth noting that the guide hole 9 is arranged above the inner spiral plate 7.

[0035] The sulfur-containing gas enters the inner spiral channel at high speed along the tangential direction of the side wall of the inner centrifugal cylinder 5 through the air inlet pipe 6. The gas rotates in the channel. Under the action of centrifugal force, the granular sulfur-containing substances and other impurities in the gas are thrown to the wall of the inner centrifugal cylinder 5, and slide down along the wall, and finally fall into the collecting hopper 101 below. Part of the gas that has been initially separated passes through the inclined guide holes 9 on the inner centrifugal cylinder 5 and enters the outer spiral channel from the inner spiral channel for secondary centrifugal separation to further remove the residual particulate impurities. The separated impurities also fall into the collecting hopper 101.

[0036] The spray desulfurization system is divided into a coarse spray layer 10, a fine spray layer 11 and a buffer spray layer 12 from bottom to top. The coarse spray layer 10, the fine spray layer 11 and the buffer spray layer 12 are all horizontally arranged grid structures, and are respectively equipped with nozzles of different types and densities.

[0037] After centrifugal separation, the gas rises to the spray desulfurization system and passes through the coarse spray layer 10, the fine spray layer 11 and the buffer spray layer 12 in sequence. In the coarse spray layer 10, a large amount of alkaline spray liquid is sprayed by a large flow and large angle nozzle to perform preliminary scrubbing on the gas and remove most of the sulfur-containing substances. The gas then enters the fine spray layer 11, where the nozzle density is higher and the spray droplets are finer, further absorbing the residual sulfur-containing components in the gas. Finally, in the buffer spray layer 12, a small amount of spray liquid plays a buffering and supplementary scrubbing role to ensure that the gas is fully desulfurized. During this process, the spray liquid reacts chemically with the sulfur-containing gas, converting the sulfide into a water-soluble substance, which falls into the collection device below (i.e., the collecting hopper 101) along with the spray liquid.

[0038] The adsorption and shedding system includes an adsorption plate 35 , which is arranged on the inner wall of the central tower 102 . The interior of the adsorption plate 35 is filled with activated carbon, and the activated carbon particles are evenly laid.

[0039] After spray desulfurization, the gas continues to rise and enters the adsorption desulfurization system. The gas passes through adsorption plates 35 installed on the inner wall of central tower 102. The activated carbon filled in adsorption plates 35 has a rich pore structure and a large specific surface area, which can effectively adsorb trace sulfur-containing substances remaining in the gas, further purifying the gas. The purified gas ultimately enters gas collection hopper 103 and exits the device through outlet pipe 2.

[0040] Example 2

[0041] Based on the first embodiment, Figure 3-Figure 6 As shown, the inner spiral plate 7 is installed on the inner wall of the central tower 102 through an installation assembly, a sealing box 13 is installed on the outer wall of the central tower 102, and a transmission hole is opened on the central tower 102 to achieve communication with the interior of the sealing box 13. A drive motor 14 is provided on the sealing box 13, and the drive motor 14 drives the installation assembly and the inner spiral plate 7 to rotate through the transmission assembly.

[0042] Specifically, the mounting assembly includes a fixed ring 15 and an extended vertical plate 16, and the fixed ring 15 is fixed on the inner wall of the central tower 102, the extended vertical plate 16 is arranged at the lower end of the inner spiral plate 7, and the lower ends of multiple extended vertical plates 6 are commonly provided with a connecting ring 17, the connecting ring 17 is located in the inner centrifugal cylinder 5, and the lower end of the connecting ring 17 is connected to the driving ring 19 through the extension frame 18, and the upper end of the driving ring 19 is provided with a limiting ring 20, and the lower end face of the fixed ring 15 is provided with an annular limiting groove 21, and the limiting ring 20 is movably connected in the annular limiting groove 21, which can not only limit the radial movement of the driving ring 19, but also ensure its rotation around the central axis, thereby ensuring the stability of the inner spiral plate 7 during rotation.

[0043] The transmission assembly includes a gear ring 22 , and the gear ring 22 is compounded on the drive ring 19 . A drive gear 23 is installed at the output end of the drive motor 14 , and the drive gear 23 is meshed with the gear ring 22 through a transmission hole.

[0044] refer to Figure 7 — Figure 11 , a limited slot 24 is vertically provided on the inner wall of the inner centrifugal cylinder 5, and a mobile connecting seat 25 is slidably connected in the limited slot 24, and a cleaning spoiler 26 is rotatably connected on the mobile connecting seat 25, and a movable chamber 27 is provided in the mobile connecting seat 25, and a steering gear 28 is rotatably connected in the movable chamber 27, and the steering gear 28 is coaxially arranged with the cleaning spoiler 26, and a steering gear plate 29 is also slidably connected in the movable chamber 27, and the steering gear plate 29 is meshed with the steering gear 28, an extension hole 30 is provided on the mobile connecting seat 25, a meshing hole 31 is provided on the inner centrifugal cylinder 5, a mounting seat 32 is installed on the inner centrifugal cylinder 5, a steering gear 33 is installed in the mounting seat 32, and the rotating gear 33 is driven by the steering motor, a steering gear plate 34 is compounded on the steering gear plate 29, and the steering gear 33 is meshed with the steering gear plate 34 through the meshing hole 31, and a one-way bearing is installed between the rotating gear 33 and the output shaft of the rotating motor.

[0045] Since the inner spiral plate 7 is in contact with the initial gas, it is easy to produce more impurities attached. When the upper and lower surfaces of the inner spiral plate 7 need to be cleaned, first ensure that the cleaning spoiler 26 is in a vertical state (such as Figure 5 As shown), at this time, the upper and lower ends of the cleaning spoiler 26 are against the upper and lower end surfaces of the two adjacent inner spiral plates 7 (that is, against the inner wall of the inner spiral channel). It is worth noting that the number of cleaning spoilers 26 is equal to the number of inner spiral plates 7. Subsequently, the driving motor 14 on the sealing box 13 is started, and the driving gear 23 at its output end begins to rotate. The driving gear 23 engages with the gear ring 22 compounded on the limiting ring 20 through the transmission hole, thereby driving the gear ring 22 to rotate. Since the limiting ring 20 is movably connected to the annular limiting groove 21 on the lower end surface of the fixing ring 15, it plays a role. The limiting effect causes the gear ring 22 to rotate, driving the connected drive ring 19, extension frame 18, connecting ring 17, extension vertical plate 16 and inner spiral plate 7 to rotate together around the axis of the central tower 102. When the inner spiral plate 7 rotates, the cleaning spoiler 26 on the inner wall of the inner centrifugal cylinder 5 begins to play a role. The cleaning spoiler 26 remains stationary during the rotation of the inner spiral plate 7, but under the push of the inner spiral plate 7, the mobile connecting seat 25 slides up and down in the limiting slide groove 24 to ensure that the cleaning spoiler 26 can comprehensively clean the inner spiral plate 7.

[0046] During the rotation of the inner spiral plate 7, the mobile connecting seat 25 slides up and down within the limiting chute 24, pushing the cleaning spoiler 26 to move along the surface of the inner spiral plate 7 for cleaning. At this time, to ensure that the angle of the cleaning spoiler 26 does not change, the steering gear 29 can only slide in a straight line within the movable cavity of the mobile connecting seat 25 and cannot rotate freely. When the mobile connecting seat 25 slides up and down, the position of the steering gear 29 within the movable cavity is relatively fixed and will not move arbitrarily due to external forces. Because the tooth profile of the steering gear 29 and the steering gear 28 are closely matched, the rotational freedom of the steering gear 28 is limited, thereby ensuring that the cleaning spoiler 26 always maintains a vertical angle during the up and down movement, stably cleaning the inner spiral plate 7. At the same time, the one-way bearing between the rotating gear 33 and the output shaft of the rotating motor ensures that when the mobile connecting seat 25 slides, even if the steering rack 34 moves with it, it will not drive the rotating gear 33 to rotate, thereby avoiding the rotation of the rotating gear 33 and the transmission of torque through the steering rack 34 and the adjustment rack 29, resulting in a change in the angle of the cleaning spoiler 26.

[0047] When the cleaning spoiler 26 is not needed to clean the inner spiral plate 7, the cleaning spoiler 26 can be used as a spoiler. First, the steering motor drives the steering gear 33 in the mounting seat 32 to rotate. The steering gear 33 engages with the steering gear 34 on the steering rack 29, driving the steering rack 29 to slide in the movable cavity of the movable connecting seat 25. When the steering rack 29 slides, it engages with the steering gear 28, causing the steering gear 28 to rotate, thereby driving the coaxially arranged cleaning spoiler 26 to rotate around its own axis, adjusting the angle of the cleaning spoiler 26, thereby generating disturbances in the gas and further enhancing the centrifugal separation effect.

[0048] When the mobile connecting seat 25 slides in the limiting slide groove 24, the steering gear plate 34 moves accordingly. The one-way bearing between the rotating gear 33 and the output shaft of the rotating motor can ensure that the engagement of the rotating gear plate 34 with the rotating gear 33 during the movement will not cause the rotating gear plate 34 and the adjusting gear plate 29 to move, thereby avoiding the change in the angle of the cleaning spoiler 26 after the adjusting gear plate 29 moves.

[0049] It is worth noting that when the cleaning spoiler 26 is not needed to clean the inner spiral plate 7, nor is it needed to disturb the gas, the angle of the cleaning spoiler 26 can be rotated to a state roughly parallel to the inner spiral plate 7. At this time, the effect of the cleaning spoiler 26 on the gas disturbance is minimized, which can reduce the energy loss during the gas flow process and keep the gas in a relatively stable flow state in the inner spiral channel.
