Description

Technical Field

[0001] This invention relates to the field of deactivated desulfurization particle regeneration technology, specifically to a continuous thermal regeneration treatment device for deactivated desulfurization particles. Background Technology

[0002] Dry flue gas desulfurization typically uses activated carbon and activated coke particles to adsorb sulfur dioxide in the flue gas. After long-term adsorption of sulfates and sulfides, the internal pores of the particles become blocked, and the adsorption capacity decreases significantly, resulting in a large number of deactivated desulfurization particles. High-temperature thermal regeneration devices are commonly used in the industry to decompose the internal adsorbed impurities through high-temperature pyrolysis, restore the pores and desulfurization activity of the particles, and achieve repeated use.

[0003] In the existing technology, many vertical multi-layer regeneration furnaces adopt a structure in which a fixed outer ring large disc is arranged alternately with small diameter solid receiving plates, and the material falls layer by layer in a serpentine manner, such as: application number 201810660243.6, 202021708286.X, CN201721609455.0.

[0004] The three patents above have the same basic structure for layered material feeding in their furnaces. They all rely on a central main shaft to drive an integrated fixed rake to push charcoal particles, completing the entire process of drying, pyrolysis, and activation in layers. However, the following problems exist during long-term continuous production on-site: The rakes that come with the equipment are all fixed as a whole, and the tilt angle of the pusher cannot be adjusted individually. If you want to change the material conveying speed on the furnace plate or adjust the residence time of a single layer of charcoal particles, you can only adjust the rotation speed of the central spindle. The adjustment method is limited and may also cause conflicting production problems.

[0005] If it is necessary to speed up material feeding, shorten material residence time, and increase equipment throughput on site, the only option is to increase the spindle speed. After the speed is increased, the frequency of the rake sweeping across the material layer increases simultaneously, and the activated carbon particles continuously and violently collide and rub against each other, resulting in a significant increase in wear and pulverization losses. Conversely, for deactivated particles with high sulfur content and many adsorbed impurities, it is necessary to extend the heating time to ensure that sulfates are fully decomposed, which requires reducing the spindle speed. After the speed decreases, the rake turns over the material layer less often, and the material accumulates statically for a long time. At high temperatures, the molten sulfate on the particle surface is very easy to agglomerate. After the thick material layer accumulates, the permeability becomes poor, and the sulfur vapor generated by pyrolysis cannot be quickly dissipated. It will be re-adsorbed into the pores of the activated carbon, ultimately resulting in incomplete regeneration and inconsistent activity of the finished product.

[0006] Therefore, it is difficult to separately control the material conveying speed and the intensity of material layer turning, and the material residence time and turning effect are tied together. The adaptability to different deactivation degrees and different particle sizes of desulfurization particles is very poor.

[0007] Based on this, the present invention designs a continuous thermal regeneration treatment device for deactivated desulfurization particles to solve the above problems. Summary of the Invention

[0008] The purpose of this invention is to provide a continuous thermal regeneration treatment device for deactivated desulfurization particles to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a continuous heat regeneration treatment device for deactivated desulfurization particles, comprising a heating furnace, a feed inlet at the top of the heating furnace, and a discharge pipe fixedly connected to the bottom. A rotating shaft is rotatably connected inside the heating furnace. Multiple vertically distributed support plates are fixedly connected to the inner wall of the heating furnace. A through hole is formed at the center of each support plate. A receiving plate is provided between adjacent support plates. The receiving plate is fixedly connected to the inner wall of the heating furnace, and its diameter is smaller than the diameter of the inner wall of the heating furnace. A material discharge channel is formed between the inner wall of the heating furnace and the outer surface of the receiving plate. Each support plate is provided with at least one fixed rod and an adjusting component. A first lever is rotatably connected to the bottom of the fixed rod near the inner wall of the heating furnace. The first lever is inclined from the rotation center towards the center of the support plate. The length of the first lever is greater than the radial length of the solid area of ​​the support plate. The adjusting component is used to adjust the tilt angle of the first lever around its own rotation axis. Each receiving plate and the inner bottom wall of the heating furnace are equipped with a second lever that is fixedly connected to the rotating shaft. The second lever is used to push the material falling onto the receiving plate into the material discharge channel.

[0010] As a further embodiment of the present invention, the first lever includes an outer segment and an inner segment, the outer end of the outer segment is rotatably connected to the outer end of the fixed rod, and the inner segment is rotatably hinged to the inner end of the outer segment. The adjustment component is used to drive the outer section rod to deflect around the rotation axis, and can drive the inner section rod to rotate synchronously while the outer section rod rotates.

[0011] As a further embodiment of the present invention, the adjusting assembly includes a slide rod that is slidably connected along the axial direction of the fixed rod, an inclined support rod that is rotatably connected to the slide rod, the other end of the support rod being rotatably connected to the outer section rod near the inner end, the support rod having an extension portion fixedly provided, a sliding groove being provided at the top of the inner section rod, a positioning member being provided on the extension portion, the bottom end of the positioning member extending into the sliding groove, and the positioning member being able to slide along the sliding groove and rotate relative to the sliding groove.

[0012] As a further embodiment of the present invention, the positioning member is sleeved outside the extension and slides in cooperation with the extension, and the extension is equipped with a resisting screw for limiting the positioning member.

[0013] As a further aspect of the present invention, the length of the outer section of the rod is greater than the length of the inner section of the rod.

[0014] As a further embodiment of the present invention, several protruding ridges are fixedly provided on the pushing surfaces of both the outer and inner sections of the rod, and the protruding ridges are arranged at intervals along the length direction of the outer and inner sections of the rod.

[0015] As a further embodiment of the present invention, with the end closest to the inner wall of the heating furnace as the starting end and the end closest to the rotating shaft as the ending end, the height of the protruding ridges on the outer section rod and the inner section rod increases sequentially from the starting end to the ending end.

[0016] As a further aspect of the present invention, it also includes a control component for controlling the sliding stroke of the slide bar along the fixed rod. The control component includes a guide frame that is slidably connected to the rotating shaft and extends to the top of the heating furnace. Movable rods are provided at positions corresponding to the slide bar on the guide frame. One end of the movable rod is rotatably connected to the guide frame, and the other end is rotatably connected to the slide bar.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This invention, through an angle-adjustable first lever, allows for independent adjustment of the tilt angle of the first lever while maintaining a constant shaft rotation speed and material turning frequency. This overcomes the problem in existing technologies where the shaft rotation speed determines the material disturbance intensity, adjusts the radial propulsion speed of the material and its residence time inside the heating furnace, and improves the equipment's adaptability to desulfurization particles with different deactivation degrees and particle sizes.

[0020] Please see Figures 1-12 This invention provides a technical solution: a continuous heat regeneration treatment device for deactivated desulfurization particles, comprising a heating furnace 1, a feed inlet 101 at the top of the heating furnace 1, and a discharge pipe 102 fixedly connected to the bottom. A rotating shaft 2 is rotatably connected inside the heating furnace 1. A plurality of vertically distributed support plates 3 are fixedly connected to the inner wall of the heating furnace 1. A through hole 4 is opened through the center of the support plate 3. A receiving plate 5 is provided between adjacent support plates 3. The receiving plate 5 is fixedly connected to the inner wall of the heating furnace 1, and the diameter of the receiving plate 5 is smaller than the diameter of the inner wall of the heating furnace 1. A material discharge channel 6 is formed between the inner wall of the heating furnace 1 and the outer circular surface of the receiving plate 5. Each support plate 3 is provided with at least one fixed rod 7 and an adjustment component. A first lever 8 is rotatably connected to the bottom end of the fixed rod 7 near the inner wall of the heating furnace 1. The first lever 8 is inclined from the rotation center towards the center of the support plate 3. The length of the first lever 8 is greater than the radial length of the solid area of ​​the support plate 3. The adjustment component is used to adjust the tilt angle of the first lever 8 around its own rotation axis. Each receiving plate 5 and the inner bottom wall of the heating furnace 1 are provided with a second lever 9 fixedly connected to the rotating shaft 2. The second lever 9 is used to push the material falling onto the receiving plate 5 into the material discharge channel 6.

[0021] like Figures 1 to 5 As shown: Deactivated desulfurization particles are fed into the furnace body through the feed inlet 101 at the top of the heating furnace 1. The material falls layer by layer onto the surface of each layer of support plate 3. The support plate 3 and the receiving plate 5 are arranged alternately, and the material forms a serpentine continuous falling path from top to bottom along the direction from La to Lb. The material falling on the support plate 3 is pushed radially by the first lever 8, passes through the through hole 4 opened in the center of the support plate 3 and falls onto the surface of the lower receiving plate 5. The material on the receiving plate 5 is pushed by the second lever 9 that rotates synchronously with the rotating shaft 2, and is conveyed downward through the falling channel 6 formed by the inner wall of the heating furnace 1 and the outer circular surface of the receiving plate 5. The particles move layer by layer and are continuously heated, completing the drying, pyrolysis and activation processes in sequence. The regenerated finished particles are finally discharged from the discharge pipe 102 at the bottom of the heating furnace 1.

[0022] Figure 6 A schematic diagram of the first lever 8 pushing the material on the surface of the support plate 3 toward the central through hole 4: Point O is the rotation fulcrum of the first lever 8, O1 is the center of the support plate 3, the dashed line L is the axial reference line extending from point O of the first lever 8, and the first lever 8 is arranged at an inclination from point O to point O1; R is the included angle formed between the first lever 8 and the outer circle of the support plate 3.

[0023] The rotating shaft 2 drives the first lever 8 to rotate counterclockwise. Relying on the radial pushing force generated by the inclined first lever 8, the material on the support plate 3 near point O is continuously pushed towards the central through hole 4. The material passes through the through hole 4 and falls onto the surface of the receiving plate 5; subsequently... Figure 5 As shown, the inclined second lever 9 pushes the material on the receiving plate 5, causing it to fall down along the material drop channel 6 to the next layer of support plate 3.

[0024] Adjustments to speed up material feeding and shorten material residence time: The rotating shaft 2 drives the first lever 8 and the second lever 9 to rotate at a constant speed. The speed at which the material on the support plate 3 is conveyed to the receiving plate 5 is determined by the tilt angle of the first lever 8: the smaller the included angle R, the greater the overall tilt of the first lever 8 (the maximum tilt angle of this device is controlled within 35°). The greater the radial pushing force of the pushing surface of the first lever 8 (the working surface that contacts the material during the rotation of the lever) toward the center O1 of the support plate, the faster the material is fed out, and the shorter the time the material stays on the support plate 3 for heating.

[0025] If it is necessary to slow down the feeding speed and extend the time the material stays heated, simply increase the value of the included angle R.

[0026] The second lever 9 only serves to convey the material on the receiving plate 5 downwards. The second lever 9 can be directly set to the maximum tilt angle to ensure that the material on the receiving plate 5 is conveyed downwards as quickly as possible. At the same time, the overall diameter of the receiving plate 5 is relatively small, and the material itself has a higher conveying efficiency. Therefore, there is no need to dynamically adjust the tilt angle of the second lever 9 to meet the requirements of continuous production.

[0027] This invention, through the first adjustable lever 8, can independently adjust the tilt angle of the first lever 8 under the premise of constant shaft rotation speed and constant material turning frequency, overcoming the problem in the prior art that the rotation speed of the shaft 2 determines the disturbance intensity of the material, adjusting the radial propulsion speed of the material and the residence time inside the heating furnace 1, and improving the equipment's adaptability to desulfurization particles with different deactivation degrees and different particle sizes.

[0028] The first lever 8 includes an outer segment 801 and an inner segment 802. The outer end of the outer segment 801 is rotatably connected to the outer end of the fixed rod 7, and the inner segment 802 is rotatably hinged to the inner end of the outer segment 801. The length of the outer segment 801 is greater than the length of the inner segment 802.

[0029] The adjustment assembly includes a slide rod 10 that is slidably connected along the axis of the fixed rod 7. An inclined support rod 11 is rotatably connected to the slide rod 10. The other end of the support rod 11 is rotatably connected to the outer section rod 801 near the inner end. An extension 12 is fixedly provided on the support rod 11. A groove is provided at the top of the inner section rod 802. A positioning member 13 is provided on the extension 12. The bottom end of the positioning member 13 extends into the groove. The positioning member 13 can slide along the groove and rotate relative to the groove.

[0030] The support plate 3 has a central through hole 4 in a large annular hollow disc with a large radial width. The outer ring has a larger radius of rotation and a linear velocity much higher than that of the inner ring near the rotating shaft 2. The difference in linear velocity between the inner and outer rings is large. If the material is spread throughout the entire radial area of ​​the support plate 3, and a single integral lever is used, the pushing force of the inner and outer rings will be exactly the same. This will result in the outer ring material being conveyed too fast and the inner ring material accumulating, leading to uneven distribution of the material layer thickness.

[0031] The following example illustrates the adjustment process by reducing the included angle R to Ra and increasing the material feeding speed. Figures 7 to 10 : During adjustment, the control component drives the slide rod 10 to move slightly horizontally along the fixed rod 7 towards the rotating shaft 2; one end of the support rod 11 is hinged to the slide rod 10, and the other end is hinged to the outer section rod 801. The displacement of the slide rod 10 will cause the support rod 11 to rotate counterclockwise around its own rotation center O2. Figure 8 To adjust the initial state before adjustment.

[0032] The dashed line L1 is the axial extension reference line of the outer section rod 801, and the dashed line L2 is the axial extension reference line of the inner section rod 802. Before adjustment, the angle between L1 and L2 is Rb.

[0033] The swinging of the support rod 11 will push the outer section rod 801 to rotate counterclockwise around the pivot point O, reducing the included angle R between the outer section rod 801 and the outer circular surface of the support plate 3 to Ra. When the support rod 11 rotates, the integrally connected extension 12 moves synchronously, and the end positioning member 13 slides in the top groove of the inner section rod 802 and rotates synchronously, causing the inner section rod 802 to rotate counterclockwise around its own pivot point O3. The adjusted state is as follows. Figure 9 As shown; at this time, the included angle between L1 and L2 is expanded from Rb to Rb1, so that the inner section rod 802 can rotate synchronously with the outer section rod 801 while automatically deflecting a certain angle, forming a differentiated pushing structure with a small outer ring tilt angle and a large inner ring tilt angle.

[0034] The outer ring uses a small tilt angle to adapt to its high linear velocity, preventing materials from flowing rapidly toward the center; the inner ring increases the tilt angle to compensate for its low rotational linear velocity, avoiding material accumulation. Ultimately, this ensures that the material conveying speed of the entire support plate 3 is uniform and the material layer thickness is basically consistent, avoiding problems such as overheating of particles due to excessively thick local material layers and incomplete regeneration of thin material layers.

[0035] Meanwhile, the outer section rod 801 is longer than the inner section rod 802. Most of the outer ring of the support plate 3 is covered by the long outer section rod 801, and the overall feeding speed of the equipment is roughly adjusted by the tilt angle of the outer section rod 801; only the narrow inner ring area is covered by the short inner section rod 802.

[0036] The outer ring has a larger material load capacity, and the long outer rod 801 has a sufficient tilt angle adjustment range, which makes it easy to change the processing capacity of the equipment in a wide range; the short inner rod 802 only supplements the thrust for a small amount of accumulated material in the inner ring, and will not interfere with the overall material distribution adjustment effect of the outer rod 801 due to the excessive length of the inner rod.

[0037] The positioning member 13 is sleeved on the outside of the extension 12 and slides with the extension 12. The extension 12 is equipped with a resisting screw 17 for limiting the positioning member 13.

[0038] like Figure 10 As shown, the distance between the positioning member 13 and the rotation center O3 of the inner section rod 802 is L3. The positioning member 13 can slide along the extension 12. After adjusting to the correct position, tighten the resisting screw 17 to lock the relative position of the positioning member 13 and the extension 12.

[0039] The closer the positioning element 13 is to O3, the larger the deflection angle of the inner rod 802 can be generated by a small swing of the extension 12; the farther the positioning element 13 is from O3, the smaller the deflection angle of the inner rod 802 under the same swing amplitude; the maximum differential deflection angle of the inner rod 802 relative to the outer rod 801 can be controlled by changing the length of L3 between the positioning element 13 and O3.

[0040] Several protruding ribs 14 are fixedly provided on the pushing surfaces of the outer section rod 801 and the inner section rod 802. The protruding ribs 14 are arranged at intervals along the length direction of the outer section rod 801 and the inner section rod 802. Taking the end near the inner wall of the heating furnace 1 as the starting end and the end near the rotating shaft 2 as the ending end, the height of the protruding ribs 14 on the outer section rod 801 and the inner section rod 802 increases sequentially from the starting end to the ending end.

[0041] like Figure 5 and Figure 11 As shown; During operation, the spindle speed remains constant; only the tilt angle of the lever is adjusted. The tilt angle of the lever is increased, and the material pushing speed is faster: the inner section rod 802 and the outer section rod 801 tilt inward at a greater angle. The horizontal distance between the leftmost convex rib 14 of the outer section rod 801 and the rightmost convex rib 14 of the inner section rod 802 will be reduced, but the height of the convex rib 14 in the working state will be increased. When inserted into the material layer, it can play a strong turning effect, which can turn up the particles at the bottom that have not been fully heated, enhance the air permeability of the material layer, and make up for the problems of short material residence time and incomplete decomposition. Adjusting the tilt angle of the lever to reduce material conveying speed: The horizontal distance between the leftmost ridge 14 of the outer section rod 801 and the rightmost ridge 14 of the inner section rod 802 will increase, the effective turning height of the ridge 14 will be reduced, the stirring of particles will be gentler, the collision and wear of particles will be reduced, and the continuous turning will prevent the material from clumping and sulfur vapor from being adsorbed again.

[0042] The outer rod 801 and the inner rod 802 can be adjusted at their angles independently, and the protrusions 14 of the two sections can also change the material turning force accordingly, adapting to different material feeding conditions of the outer and inner rings of the support plate 3 respectively.

[0043] It also includes a control component for controlling the sliding stroke of the slide rod 10 along the fixed rod 7. The control component includes a guide frame 15 that is slidably connected to the rotating shaft 2 and extends to the top of the heating furnace 1. Movable rods 16 are provided at positions corresponding to the slide rod 10 on the guide frame 15. One end of the movable rod 16 is rotatably connected to the guide frame 15, and the other end is rotatably connected to the slide rod 10.

[0044] like Figure 11 and Figure 12 As shown: The guide frame 15 is slidably connected to the rotating shaft 2 and extends to the top of the heating furnace 1. The guide frame 15 and the slide rod 10 are hinged and driven by the movable rod 16. A threaded rod 18 is threadedly connected between the top of the rotating shaft 2 and the guide frame 15. The guide frame 15 is raised and lowered by rotating the threaded rod 18. The slide rod 10 is pushed and pulled along the fixed rod 7 by the movable rod 16 to achieve adjustment.
