Description

Technical Field

[0001] This invention relates to the technical field of desulfurization in desulfurization towers, and in particular to a super activated carbon tail gas desulfurization uniform dispersion device for desulfurization towers. Background Technology

[0002] Flue gas containing sulfur dioxide, after pretreatment, enters a desulfurization tower containing super activated carbon through the main pipeline. The sulfur dioxide in the flue gas is adsorbed on the surface of the activated carbon and reacts chemically with the oxygen in the flue gas under the action of a catalyst to produce sulfur trioxide. After slowly reaching a certain saturation concentration, it reacts chemically with the water entering the desulfurization tower to produce dilute sulfuric acid, which is then recovered and reused through the pipeline.

[0003] Super activated carbon, as a high-performance adsorbent material, boasts an extremely high specific surface area (typically >2000 m²). 2 With its well-developed pore structure (micropore-mesopore synergy) and tunable surface chemistry, it exhibits unique advantages in flue gas desulfurization (especially in small and medium-scale or special scenarios).

[0004] Based on the operation mode of the desulfurization tower, the application of super activated carbon can be divided into three mainstream processes: fixed bed, moving bed (converter) and fluidized bed. In the fixed bed desulfurization tower, activated carbon is filled in the fixed layer inside the tower, and the flue gas passes through the bed horizontally or vertically to complete the desulfurization.

[0005] Chinese patent CN118767622A discloses a super activated carbon desulfurization device for sulfuric acid tail gas treatment, belonging to the field of sulfuric acid tail gas treatment technology. It utilizes a material-turning plate to flip the super activated carbon, allowing the super activated carbon at the bottom of the super activated carbon holder to move to the top. A connecting shaft drives spiral blades to move the bottommost super activated carbon, improving the flowability of the super activated carbon within the desulfurization cylinder. This ensures sufficient contact between the sulfuric acid tail gas and the super activated carbon, enhancing the adsorption effect. Simultaneously, the sprayed dilute sulfuric acid also makes sufficient contact with the super activated carbon, further improving the rinsing effect and fully utilizing its adsorption capacity. Secondly, when discharging super activated carbon, the motor drives the connecting shaft to reverse, so that the super activated carbon can be fed into the discharge cylinder during the rotation of the spiral blades. The super activated carbon can be discharged by opening the discharge valve, without the need for manual assistance to turn and throw, which improves the convenience of operation and is conducive to the efficient treatment of sulfuric acid tail gas. The above-mentioned related technologies have the following defects: the flow trajectory of the tail gas after mixing with water vapor in the tower is generally vertical. This causes the tail gas to not react fully in the tower. Many sets of spray components need to be set in the tower to allow the tail gas to react fully. This results in a high overall height of the tower and insufficient flow pressure of the airflow on the upper side of the tower. Summary of the Invention

[0019] Optionally, the liquid extraction mechanism includes a vertical box and a movable pressure block.

The liquid extraction pipe and the liquid spraying frame are both fixed to and connected to the vertical box, and the liquid extraction pipe is located on the upper side of the liquid spraying frame.

[0020] A water-blocking plate is provided on the lower side of the movable pressure block. The water-blocking plate is inserted into the inside of the vertical box and moves within the vertical box.

[0021] Optionally, the mixing plate mechanism includes an arc plate and multiple variable diameter cylinders, with the variable diameter cylinders mounted on one side of the arc plate.

[0025] Optionally, the distance between the end of the liquid extraction pipe connected to the vertical box and the end of the liquid spraying frame connected to the vertical box is greater than the maximum distance between the movable pressure block and the water-separating plate. When the movable pressure block moves to the uppermost side of the vertical box, the water-separating plate is located on the upper side of the liquid spraying frame, and the liquid extraction pipe is located between the movable pressure block and the water-separating plate.

[0026] In summary, the present invention has the following beneficial technical effects:

[0027] This invention incorporates components such as a vertical mixing mechanism and a longitudinal mixing and gas transmission mechanism. The exhaust gas is conveyed upwards from the bottom and mixed with the liquid vapor. The longitudinal mixing and gas transmission mechanism allows the water vapor to move longitudinally within the tower, increasing the longitudinal movement distance of the mixture. Simultaneously, the rotation of the vertical mixing mechanism agitates the gas-liquid mixture, further increasing the length of its movement trajectory within the tower. This ensures the gas-liquid mixture has sufficient distance to react within the tower, allowing for thorough desulfurization of the exhaust gas without requiring sufficient height or numerous sets of liquid spraying mechanisms.

[0028] This invention, through the arrangement of components such as a movable turntable, a synchronous turntable, a linkage frame, and a variable diameter rod, allows the gas-liquid mixture below the baffle plate to enter the hollow cylinder through the air inlet groove. When the smallest outer diameter portion of the variable diameter rod is inside the small hole, the gas-liquid mixture flows through the gap between the small hole and the variable diameter rod to the space between the movable and synchronous turntables. Simultaneously, the variable diameter rod, rotating with the shaft, mixes the gas-liquid mixture. When the movable turntable moves backward, aligning the small hole with the middle portion of the variable diameter rod, the airflow stops moving between the synchronous and movable turntables, gradually increasing the pressure between them. This increased pressure enhances the mixing effect. The movable turntable pushes the linkage frame, causing the variable diameter rod to move backward, moving its middle portion into the range of the large hole. This allows the gas-liquid mixture between the synchronous and movable turntables to flow backward through the gap between the large hole and the variable diameter rod. This process of repeatedly pressurizing and mixing the gas-liquid mixture backward enhances the absorption effect on the exhaust gas.

[0029] This invention uses an arc plate and a variable diameter cylinder. The vertical shaft and the vertical cylinder drive the connected arc plate to rotate relative to each other. As the opposing arc plates rotate in opposite directions, they mix and stir the gas-liquid mixture, creating a countercurrent airflow that increases the mixing effect and the flow path. At the same time, when the airflow passes through the variable diameter cylinder while the arc plate is rotating, the pressure of the airflow changes due to the different cross-sections at both ends of the variable diameter cylinder. This pressure-enhancing effect increases the absorption of exhaust gas. Attached Figure Description

[0040] The following is in conjunction with the appendix Figures 1-9 The present invention will be described in further detail below.

[0041] This invention discloses a super-activated carbon tail gas desulfurization uniform dispersion device for desulfurization towers. For example... Figures 1-9 As shown, it includes a tower body 1, an exhaust pipe 2, and a liquid supply pipe 3. The exhaust pipe 2 is fixedly installed on the circumference of the tower body 1 and is connected. A liquid spraying mechanism 4 is installed inside the tower body 1. The liquid spraying mechanism 4 passes through the tower body 1 and is connected to the liquid supply pipe 3.

[0042] In this embodiment, the spraying mechanism 4 consists of multiple ring-shaped pipes that are connected in a ring shape. Multiple spray heads that are evenly distributed are installed on the bottom surface of the ring pipes, and the liquid supply pipe 3 fills the ring pipes with liquid.

[0043] A vertical mixing mechanism 5 is installed inside the tower body 1 and below the spraying mechanism 4, and a baffle plate 8 is installed inside the tower body 1 and below the vertical mixing mechanism 5.

[0044] The vertical mixing mechanism 5 includes a vertical shaft 51 and a vertical cylinder 52. The vertical shaft 51 and the vertical cylinder 52 are coaxially rotatably installed inside the tower body 1. A mixing plate mechanism 53 is installed on the outer surface of the vertical shaft 51 and the inner wall of the vertical cylinder 52. The power mechanism 9 provides the vertical shaft 51 and the vertical cylinder 52 with opposite rotational power.

[0045] The mixing plate mechanism 53 includes an arc plate 531 and multiple variable diameter cylinders 532. The variable diameter cylinders 532 are installed on one side of the arc plate 531. The arc plate 531 is curved in an arc shape. The vertical shaft 51 and the vertical cylinder 52 are respectively fixed to the corresponding arc plate 531. The power mechanism 9 drives the vertical shaft 51 and the vertical cylinder 52 to rotate relative to each other, and then drives the corresponding connected arc plate 531 to rotate relative to each other.

[0046] The relative rotation of the arc plate 531 agitates the airflow, increasing the mixing effect and causing the airflow to flow laterally, thus increasing the distance of the airflow trajectory.

[0047] The cross-section of the variable diameter cylinder 532 on the side closest to the vertical shaft 51 is larger than the cross-section of the other end. The arc plate 531 connected to the vertical shaft 51 and the vertical cylinder 52 is set with opposite arc bending angles. The arc plate 531 connected to the vertical shaft 51 and the vertical cylinder 52 is staggered vertically. The staggered arc plate 531 ensures that there will be no interference when rotating. When the arc plate 531 rotates, the gas-liquid mixture passes through the variable diameter cylinder 532. Due to the different cross-sections at both ends of the variable diameter cylinder 532, the pressure of the gas-liquid mixture changes as it passes through the variable diameter cylinder 532, which increases the effect of exhaust gas absorption in the gas-liquid mixture.

[0048] The baffle plate 8 is permeated by a longitudinally distributed longitudinal mixing and gas transmission mechanism 6. The longitudinal mixing and gas transmission mechanism 6 facilitates the longitudinal flow of gas-liquid mixture. The gas on the lower side of the baffle plate 8 moves to the upper side of the baffle plate 8 through the longitudinal mixing and gas transmission mechanism 6.

[0049] The upper surface of the baffle water collection plate 8 is wavy with equal peaks and troughs. The bottom surface of the baffle water collection plate 8 is provided with a corresponding groove structure at the peak position on its upper surface. The longitudinal mixing and air transmission mechanism 6 is installed through the peak position of the baffle water collection plate 8. The liquid sprayed from the upper side gradually accumulates in the trough part of the baffle water collection plate 8.

[0050] A draining mechanism 7 is installed on the outside of the tower body 1. The draining mechanism 7 guides the water on the upper side of the baffle water collection plate 8 to the lower side of the baffle water collection plate 8. The draining mechanism 7 is located at the trough of the baffle water collection plate 8. A power mechanism 9 is installed on the outside of the tower body 1 to control the movement of the vertical mixing mechanism 5 and the longitudinal mixing gas transmission mechanism 6.

[0051] Inside the tower body 1, and below the baffle water collection plate 8, a super activated carbon disc is installed. When the airflow passes through the super activated carbon disc, it absorbs impurities in the exhaust gas.

[0052] The liquid discharge mechanism 7 includes a liquid extraction pipe 71, a liquid extraction mechanism 72, and a liquid spraying frame 74. The liquid extraction pipe 71 is fixed at one end near the baffle water collection plate 8 and is connected to multiple diversion pipes 73. The diversion pipes 73 penetrate the outer surface of the tower body 1. The number of diversion pipes 73 is equal to the number of troughs of the baffle water collection plate 8. The diversion pipes 73 are connected to the corresponding troughs of the baffle water collection plate 8. The liquid in the troughs of the baffle water collection plate 8 flows out through the diversion pipes 73.

[0053] The liquid extraction pipe 71 is fixed and connected to the liquid extraction mechanism 72, the liquid spraying frame 74 is fixed and connected to the liquid extraction mechanism 72, the liquid spraying frame 74 is located on the lower side of the baffle water collection plate 8, the liquid spraying frame 74 is installed through the inside of the tower body 1, and the liquid extraction mechanism 72 is located on the outside of the tower body 1.

[0054] The liquid extraction mechanism 72 includes a vertical box 721 and a movable pressure block 722. The movable pressure block 722 is fitted inside the vertical box 721 and moves within the vertical box 721. A power telescopic rod is installed at the upper end of the vertical box 721 to control the movement of the movable pressure block 722. The power telescopic rod is preferably an electric telescopic rod. The liquid extraction pipe 71 and the liquid spraying frame 74 are both fixed to and connected to the vertical box 721. The liquid spraying frame 74 is equipped with a one-way valve so that liquid can only flow from the vertical box 721 into the liquid spraying frame 74 in one direction. The liquid extraction pipe 71 is located on the upper side of the liquid spraying frame 74.

[0055] A water-blocking plate 723 is provided on the lower side of the movable pressure block 722. The water-blocking plate 723 is inserted into the vertical box 721 and moves within the vertical box 721. The water-blocking plate 723 and the movable pressure block 722 are connected by a fixed-distance telescopic rod 724.

[0056] The distance between the end of the suction pipe 71 connected to the vertical box 721 and the end of the spray rack 74 connected to the vertical box 721 is greater than the maximum distance between the movable pressure block 722 and the water baffle plate 723. When the movable pressure block 722 moves to the uppermost side of the vertical box 721, the water baffle plate 723 is located above the spray rack 74, and the suction pipe 71 is located between the movable pressure block 722 and the water baffle plate 723, so that the liquid at the trough of the baffle plate 8 can flow from the diversion pipe 73 and the suction pipe 722. The liquid flows between the movable pressure block 722 and the baffle plate 723. Then, as the movable pressure block 722 and the baffle plate 723 move downward, the movable pressure block 722 first blocks the liquid extraction pipe 71. Then, the movable pressure block 722 moves downward, and the baffle plate 723 moves to the lower side of the connection between the spray rack 74 and the vertical box 721. The movable pressure block 722 gradually moves downward and approaches the baffle plate 723, pushing the liquid between them into the spray rack 74 and spraying it into the tower body 1 for backflow.

[0057] The longitudinal mixing and air transmission mechanism 6 includes a hollow cylinder 61 and a shaft 62. The hollow cylinder 61 is installed through the crest of the baffle water collection plate 8. The shaft 62 is coaxially installed inside the hollow cylinder 61 and rotates relative to the hollow cylinder 61. The shaft 62 is rotatably connected to the baffle water collection plate 8. Both ends of the shaft 62 pass through the inner walls of both sides of the tower body 1 and rotate relative to the tower body 1. One end of the shaft 62 located outside the tower body 1 is connected to the power mechanism 9, and the power mechanism 9 outputs rotational power to the shaft 62.

[0058] In this embodiment, the power mechanism 9 includes a motor and gear set meshing and a conveyor belt drive, which transmits rotational power to the vertical shaft 51, vertical cylinder 52 and shaft 62.

[0059] A hollow cylinder 61 has an air inlet groove 63 on its bottom surface at one end and an air outlet groove 69 on its upper surface at the other end. A vent pipe 64 is installed on the upper surface of the hollow cylinder 61 and is connected to the air outlet groove 69. A horizontal pipe 65 is provided on the upper side of the baffle water-gathering plate 8. The vent pipe 64 is fixed to and connected to the horizontal pipe 65. An air outlet pipe 66 is provided at each trough of the baffle water-gathering plate 8. The air outlet of the air outlet pipe 66 is located at the bottom and is partially submerged in the liquid accumulated in the trough of the baffle water-gathering plate 8. The air outlet pipe 66 is fixed to and connected to the horizontal pipe 65. The gas-liquid mixture on the lower side of the baffle water-gathering plate 8 enters the hollow cylinder 61 through the air inlet groove 63 and then flows out from the air outlet groove 69. The airflow then enters the air outlet pipe 66 through the vent pipe 64 and is discharged from the air outlet at the bottom of the air outlet pipe 66 into the liquid accumulated at the bottom of the trough of the baffle water-gathering plate 8.

[0060] A reciprocating screw 67 is rotatably inserted into the inner side of the shaft 62. The reciprocating screw 67 is located at one end outside the shaft 62 and is fixed to the tower body 1. Multiple pressure transmission mechanisms 68 are installed inside the hollow cylinder 61. The pressure transmission mechanisms 68 are installed outside the shaft 62 and mesh with the reciprocating screw 67. The shaft 62 rotates relative to the reciprocating screw 67 during rotation.

[0061] An exhaust pipe 10 connected to the interior is installed at the upper end of the tower body 1, and a liquid outlet pipe is installed at the bottom of the tower body 1.

[0062] The pressure transmission mechanism 68 includes a movable turntable 681 and a synchronous turntable 682. The synchronous turntable 682 is fixedly sleeved on the outer surface of the shaft 62. The movable turntable 681 is fitted with the synchronous turntable 682 and is disposed inside the hollow cylinder 61. The movable turntable 681 is located on the side of the synchronous turntable 682 near the air inlet groove 63. The movable turntable 681 is slidably sleeved on the outer side of the shaft 62. The movable turntable 681 rotates synchronously with the shaft 62. After the inner ring surface of the movable turntable 681 slides through the outer surface of the shaft 62, it is threaded onto the outer surface of the reciprocating screw 67.

[0063] In this embodiment, the shaft 62 drives the movable turntable 681 to rotate synchronously. During the rotation, the movable turntable 681 engages with the reciprocating lead screw 67, and the movable turntable 681 moves back and forth towards and away from the synchronous turntable 682.

[0064] A linkage frame 683 is provided between the movable turntable 681 and the synchronous turntable 682. The linkage frame 683 is slidably sleeved on the outer surface of the shaft 62. The linkage frame 683 rotates synchronously with the shaft 62. The end face of the movable turntable 681 has multiple through holes 684. The synchronous turntable 682 has a large hole 685 at the corresponding position of each small hole 684. A variable diameter rod 686 is coaxially provided inside each small hole 684. The variable diameter rod 686 is fixed to the linkage frame 683. The linkage frame 683 rotates synchronously with the shaft 62. As the variable diameter rod 686 rotates with the linkage frame 683, it moves towards the hollow... The gas-liquid mixture inside cylinder 61 is mixed and stirred to make the gas-liquid mixture uniform. The outer diameter of the variable diameter rod 686 near the air inlet groove 63 is smaller than the inner diameter of the small hole 684. The outer diameter of the middle part of the variable diameter rod 686 is equal to the inner diameter of the small hole 684. The linkage frame 683 is fixed to the middle part of the variable diameter rod 686. The outer diameter of the variable diameter rod 686 away from the air inlet groove 63 is larger than the outer diameter of the middle part of the variable diameter rod 686. The outer diameter of the variable diameter rod 686 away from the air inlet groove 63 is equal to the inner diameter of the large hole 685. The outer diameter of the variable diameter rod 686 located on the synchronous turntable 682 away from the air inlet groove 63 is larger than the inner diameter of the large hole 685.

[0065] A retaining ring 687 is provided on the side of the movable turntable 681 near the air inlet slot 63. The retaining ring 687 is fixed to the adjacent variable diameter rod 686. When the movable turntable 681 moves forward, it pushes the retaining ring 687, which in turn drives the variable diameter rod 686 forward. This causes the large diameter end of the variable diameter rod 686 to engage with the large hole 685. When the smallest outer diameter part of the variable diameter rod 686 is inside the small hole 684, the gas-liquid mixture flows through the gap between the small hole 684 and the variable diameter rod 686 into the space between the movable turntable 681 and the synchronous turntable 682. At the same time, the large diameter end of the variable diameter rod 686 blocks the large hole 685. When the movable turntable 681 moves backward, the small hole 684 engages with the variable diameter rod 686. When the intermediate parts are in coordination, the airflow stops moving between the synchronous turntable 682 and the movable turntable 681, gradually increasing the pressure between them. This pressure increase enhances the mixing effect. The movable turntable 681 pushes the linkage frame 683 to move the variable diameter rod 686 backward, causing the middle part of the rod to move into the range of the large hole 685. This allows the gas-liquid mixture between the synchronous turntable 682 and the movable turntable 681 to flow backward through the gap between the large hole 685 and the variable diameter rod 686. The airflow passes through multiple movable turntables 681 and multiple synchronous turntables 682 in sequence, longitudinally transporting the airflow and increasing the movement distance of the gas-liquid mixture.

[0066] The working principle is as follows: the exhaust gas enters the interior of the tower body 1 through the bottom of the tower body 1, the liquid spraying mechanism 4 sprays liquid spraying inward and moves downward, the exhaust gas and the downward spray produce a counter-current mixing, the gas-liquid mixture is absorbed by the super activated carbon plate, and then the longitudinal mixing and gas transmission mechanism 6 moves the water vapor longitudinally in the tower body 1, increasing the longitudinal movement distance of the gas-liquid mixture, and transporting the gas-liquid mixture from the lower side of the baffle water collection plate 8 to its upper side. At the same time, when the vertical mixing mechanism 5 rotates, it agitates the gas-liquid mixture, further increasing the length of the movement trajectory of the gas-liquid mixture in the tower body 1. The gas-liquid mixture can react within the tower body 1 with sufficient distance, so that the tower body 1 can fully treat the exhaust gas without needing sufficient height and many sets of liquid spraying mechanisms 4.

[0067] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
