Description

Technical Field

[0001] This invention belongs to the field of desulfurization wastewater treatment technology, specifically a device for concentrating and softening desulfurization wastewater from coal-fired power plants. Background Technology

[0002] Desulfurization wastewater from coal-fired power plants contains various heavy metals, as well as high concentrations of suspended solids and inorganic salts. Inadequate treatment of desulfurization wastewater can cause significant environmental damage. Therefore, it is essential to strengthen the treatment of desulfurization wastewater, which is mainly the discharge water from the absorption tower during the wet desulfurization (limestone / gypsum method) of boiler flue gas.

[0003] Quicklime is one of the main raw materials for the concentration and softening treatment of desulfurization wastewater from coal-fired power plants. It is inexpensive, has good flocculation effect on the precipitated products, and significantly improves the acid-base reaction environment of the coagulant after being added. Therefore, the addition of quicklime in the early stage of the concentration and softening treatment process of desulfurization wastewater from coal-fired power plants is particularly important.

[0004] Quicklime is generally a powdery solid, but during processing, it may contain larger lumps. However, in the concentration and softening process of desulfurization wastewater from coal-fired power plants, the addition of quicklime and subsequent slurry preparation require ensuring that the initial quicklime is a powdery solid. Therefore, it is necessary to remove lumps and oddly shaped, large carbon slag from the quicklime to ensure the proper reaction effect of the quicklime. Currently, the separation of quicklime lumps and large carbon slag is usually done manually, which is slow and prone to accumulation at the bottom during addition, leading to incomplete reaction. Furthermore, it should be noted that this process is one step in the overall concentration and softening process of desulfurization wastewater from coal-fired power plants, and does not represent the entire process. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the problems mentioned in the background art, this invention provides a concentrated softening treatment device for desulfurization wastewater from coal-fired power plants. This device features powder-solid separation and prevents material accumulation. Through the coordinated arrangement of a first rotating box and a second rotating box, it achieves the separation of powdery and lumpy solids from quicklime and also separates and cleans the larger carbon residue within the quicklime. The coordinated arrangement of a bulking component and a moving component effectively prevents the quicklime from accumulating at the bottom of the treatment chamber during separation and falling. Furthermore, the coordinated arrangement of a shaking component and a contact component provides a secondary shaking effect on the quicklime falling to the bottom of the treatment chamber, enhancing the anti-accumulation effect.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] This invention, through the combination of a first rotating box and a second rotating box, achieves the separation of powdery solids and lumpy solids in quicklime, and separates and cleans the larger carbon residues in the quicklime. Quicklime is fed into the inner wall of the first rotating box through the feed pipe, and the quicklime is moved towards the central area of ​​the first rotating box through the inner wall of the first rotating box. The rotation of the first rotating shaft will cause the second rotating box to flip inside the first rotating box. Due to the elliptical spherical design of the second rotating box, the lumpy quicklime will be crushed, thereby effectively separating the powder and lumps of quicklime inside the first rotating box.

[0021] This invention, through the coordinated arrangement of a bulk material assembly and a moving assembly, effectively prevents the accumulation of quicklime at the bottom of the processing chamber during separation and falling. The rotation of the first rotating shaft drives the second rotating shaft and the screw to rotate via a connecting belt. When the screw rotates, it causes the moving assembly and the bulk material assembly to move together. The movement of the moving plate pulls the second connecting shaft, thereby changing the falling direction of the area between the two adjacent first and second moving plates. This ensures that when the quicklime moves downward from the inside of the first rotating box through the bulk material assembly, it can fall evenly to the bottom of the processing chamber.

[0022] This invention, through the coordination of structures such as a shaking component and a contact component, provides a secondary shaking effect on the quicklime falling to the bottom of the processing chamber, thereby improving the anti-accumulation effect. When the moving plate drives the pushing plate, the bottom end of the pushing plate will press against the contact plate, causing the contact plate to flip around the roller axis. At this time, the bottom end of the contact plate will push the shaking frame. When the upper end of the contact plate stops pressing against the shaking frame, the shaking frame will be coordinated by the second spring telescopic cylinder unit, causing it to move in the opposite direction again, thus achieving a secondary pushing effect on the quicklime falling to the bottom of the processing chamber, preventing re-accumulation and significantly improving the anti-accumulation effect.

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figures 1 to 12As shown, this invention provides a device for concentrating and softening desulfurization wastewater from a coal-fired power plant, comprising a treatment tank 1, a baffle 2 bolted to one side wall of the treatment tank 1, a connecting handle 11 fixedly connected to both the front and back of the treatment tank 1, a working tank 4 bolted to the upper end of the connecting handle 11, mounting slide plates 3 fixedly connected to both sides of the top of the treatment tank 1, a moving component 6 slidably connected to the upper end of the mounting slide plate 3, a limiting slide plate 16 slidably connected to the top of the moving component 6, the top of the limiting slide plate 16 fixedly connected to the bottom of the working tank 4, a bulk material component 13 connected to the inside of the moving component 6, the top and bottom of the bulk material component 13 being movably connected from top to bottom to the working tank 4 and the treatment tank 1 respectively, a first rotating box 7 movably connected to the inside of the working tank 4, a second rotating box 8 movably connected to the inside of the first rotating box 7, a mounting frame 9 fixedly installed on the side wall of the working tank 4 away from the baffle 2, a drive component 10 fixedly installed inside the mounting frame 9, one end of the output shaft of the drive component 10 passing through the first rotating box 7 and the second rotating box 8. Box 8 extends to the outside of working box 4. The moving component 6 is connected to the power component 15 on one side wall of the mounting frame 9. The top of working box 4 is fixedly connected to the feeding component 12. With the above scheme, through the cooperation between the above structures, the operator puts quicklime into the working box 4 through the feeding component 12. The quicklime will then enter the first rotating box 7 and the second rotating box 8. When the driving component 10 runs, the driving component 10 will make the second rotating box 8 rotate inside the working box 4 and the first rotating box 7. At this time, the second rotating box 8 will roll and stir the quicklime inside the first rotating box 7, thereby separating and crushing the blocky quicklime inside. Then the driving component 10 will drive the bulking component 13 to move through the power component 15. At this time, the bulking component 13 will make the quicklime inside the working box 4 fall evenly into the processing box 1, effectively avoiding the accumulation of quicklime when it falls, thus facilitating the subsequent addition and use of quicklime.

[0038] like Figure 3 , Figure 7 , Figure 10 and Figure 11As shown, both sides of the bottom of the working box 4 are fixedly installed with cover components 5. The bottom of the inner cavity of the processing box 1 is movably connected with a shaking component 14. The end of the shaking component 14 near the baffle 2 is fixedly connected to the baffle 2. The side of the inner cavity of the processing box 1 away from the baffle 2 is fixedly installed with a contact component 17. The top of the contact component 17 is in contact with the moving component 6. The side wall of the contact component 17 near the baffle 2 is in contact with the shaking component 14. The cover component 5 includes a cover tube 51, which is fixed to the inner wall of the processing box 1. The cover tube 51 is connected to a cover plate 52 movably inside the end near the first rotating box 7. The end of the cover plate 52 away from the cover tube 51 is in contact with the bulk material assembly 13. Two first spring retraction cylinders 53 are fixedly installed on both ends of the cover plate 52 located on one side wall inside the cover tube 51. Both first spring retraction cylinders 53 are fixedly connected to the processing box 1. The moving assembly 6 includes a moving plate 61, which is movably engaged with the top of the processing box 1. Both sides of the moving plate 61 are slidably connected to the mounting slide plate 3. A pusher plate 62 is fixedly connected to the bottom end of plate 61 away from baffle 2. The above scheme is adopted: through the cooperation of the covering tube 51 and the first spring shrink cylinder 53, the covering tube 51 and the covering plate 52 will effectively cover the blank areas on both sides of the bottom of the working box 4, preventing the quicklime inside the working box 4 from falling down from both sides of the bottom when it is stirred. At the same time, through the sleeve of the covering tube 51 and the covering plate 52, and the connection of the first spring shrink cylinder 53, it will not obstruct the movement of the subsequent bulk material assembly 13. Through the cooperation of the shaking assembly 14 and the contact assembly 17, when the moving assembly 6 moves left and right, the moving assembly 6 will squeeze the contact assembly 17. After being squeezed, the bottom end of the contact assembly 17 will strike the shaking assembly 14, thereby driving the shaking assembly 14 to move together at the bottom of the inner cavity of the processing box 1. This will give the quicklime that has fallen to the bottom of the inner cavity of the processing box 1 a secondary shaking effect, maximizing the chemical reaction of the quicklime in the subsequent process.

[0039] like Figure 3 and Figure 6As shown, the drive assembly 10 includes a servo motor 101, which is fixedly connected to the mounting bracket 9. One end of the output shaft of the servo motor 101 is fixedly connected to a first rotating shaft 102. The end of the first rotating shaft 102 away from the servo motor 101 passes through the working box 4 and the second rotating box 8 and extends to the outside of the working box 4. The surface of the first rotating shaft 102 is fixedly connected to the second rotating box 8 but not to the first rotating box 7. The first rotating box 7 is fixedly connected to the inner wall of the working box 4. The feeding assembly 12 includes a fixing plate 121, which is disposed on the top of the working box 4. Feeding pipes 122 are fixedly installed at both ends of the fixing plate 121. The bottom of the feeding pipes 122 extends into the interior of the first rotating box 7. The inner diameter of the upper opening area of ​​the two feeding pipes 122 is greater than the inner diameter of the lower opening area. Using the above scheme: Through the cooperation of the fixed plate 121 and the feed pipe 122, the operator can feed quicklime into the first rotating box 7 through the feed pipe 122. The design of the two feed pipes 122 greatly improves the feeding efficiency of quicklime and other additives. Through the cooperation of the servo motor 101 and the first rotating shaft 102, the operation of the servo motor 101 will drive the second rotating box 8 to rotate inside the first rotating box 7 through the first rotating shaft 102. The second rotating box 8 will separate the quicklime into powder and lumps and crush the larger quicklime lumps inside the first rotating box 7. At the same time, when the first rotating shaft 102 rotates, it will drive the moving component 6 to move together through the power component 15, so as to facilitate the uniform drop of quicklime after subsequent detachment.

[0040] like Figure 7 and Figure 10As shown, the bulk material assembly 13 includes a first connecting shaft 131, a second connecting shaft 132, and a third connecting shaft 133. The first connecting shaft 131 is movably connected to the lower end of the inner cavity of the working box 4. The second connecting shaft 132 is movably engaged with the inner wall of the moving assembly 6. The third connecting shaft 133 is movably connected to the upper end of the inner wall of the processing box 1. A first movable plate 134 is hinged to the middle area of ​​the first connecting shaft 131 and the second connecting shaft 132. A second movable plate 135 is hinged to the middle area of ​​the second connecting shaft 132 and the third connecting shaft 133. The shaking assembly 14 includes a shaking frame 141, which is movably connected to the bottom of the inner cavity of the processing box 1. Next, two second spring telescopic cylinders 142 are fixedly installed at both ends of the side wall near the baffle 2 of the shaking frame 141. Both second spring telescopic cylinders 142 are fixedly connected to the baffle 2. The end of the shaking frame 141 away from the second spring telescopic cylinders 142 is in contact with the abutting component 17. With the above scheme, through the mutual cooperation of the structures of the shaking frame 141 and the second spring telescopic cylinders 142, when the abutting component 17 squeezes the shaking frame 141, the shaking frame 141 will drive the second spring telescopic cylinders 142 to move towards the baffle 2. The movement of the shaking frame 141 will push the quicklime that has fallen into the bottom of the processing box 1 back and forth. The shaking frame 141 has multiple grooves inside to prevent small amounts of quicklime from accumulating when it is pushed. Through the cooperation of the first connecting shaft 131 and the second movable plate 135, the widths of the connection areas between the first connecting shaft 131 and the working box 4, and between the third connecting shaft 133 and the processing box 1, are greater than the diameters of the side walls of the first and third connecting shafts 131 and 133 that are in contact with the inner walls of the processing box 1 and the working box 4, respectively. When the moving component 6 pulls the second connecting shaft 132, the second connecting shaft 132 will drive the first movable plate 134 and the second movable plate 135. With corresponding changes, the number of bulk material components 13 is set to eight, with seven in the middle area between two adjacent first movable plates 134 and second movable plates 135. When the second connecting shaft 132 moves, the opening direction of the two adjacent third connecting shafts 133 and the second movable plate 135 will change. As a result, when the quicklime falls down from the area between the two adjacent first movable plates 134 and second movable plates 135, the change in the opening of the first movable plates 134 and second movable plates 135 will allow the quicklime to be evenly distributed at the bottom of the inner cavity of the processing box 1, avoiding accumulation.

[0041] like Figure 4 , Figure 6 , Figure 11 and Figure 12As shown, the power assembly 15 includes a screw 151. One end of the screw 151 near the baffle 2 is connected to a bearing of the moving assembly 6. A second rotating shaft 152 is threaded onto the outer wall of the screw 151. A connecting belt 153 is fitted onto the outer surface of the second rotating shaft 152. The second rotating shaft 152 is connected to the drive assembly 10 via the connecting belt 153. A limit block 154 is movably engaged on the side wall of the second rotating shaft 152 away from the baffle 2. The bottom end of the limit block 154 is fixedly connected to the processing box 1. The contact assembly 17 includes a roller 171. The roller 171 is connected to a bearing on the inner wall of the processing box 1 at the end away from the baffle 2. The middle end of the roller 171 is movable. A contact plate 172 is fitted into the moving assembly 6. The top of the contact plate 172 abuts against the moving assembly 6. A flexible spring 173 is fixedly connected to the lower end of the side wall of the contact plate 172 away from the shaking assembly 14. The end of the flexible spring 173 away from the contact plate 172 is fixedly connected to the processing box 1. The side wall of the inner cavity of the first rotating box 7 that communicates with the feeding assembly 12 is sloped. By adopting the above scheme, the sloped design of the inner side wall of the first rotating box 7 will facilitate the subsequent feeding of quicklime into the interior of the first rotating box 7 through the feeding pipe 122, and play a corresponding guiding role. The outer side wall of the first rotating box 7 is provided with a slot, the outer diameter of which is less than or equal to 1m. The first rotating box 7 is designed to allow slaked lime powder to fall downwards under normal solid conditions, while slaked lime particles larger than 1mm in diameter will not be able to fall downwards. The second rotating box 8 is designed with two elliptical hollow spheres, and the outer wall of the second rotating box 8 is in contact with the inner wall of the first rotating box 7. The rotation of the second rotating box 8 will lift up the slaked lime powder, and because the slaked lime lumps are relatively soft, the rotation of the second rotating box 8 will crush the slaked lime lumps. Through the cooperation of roller 171 and flexible spring 173, when the push plate 62 moves against the surface of the contact plate 172... During the pressing process, the contact plate 172 will rotate around the roller 171. At this time, the bottom end of the contact plate 172 will press the shaking frame 141, thereby facilitating the subsequent stirring effect of the quicklime that has fallen into the bottom of the processing box 1 through the shaking frame 141. With the cooperation of the screw 151 and the limiting block 154, when the drive assembly 10 starts to run, it will drive the second rotating shaft 152 to rotate through the connecting belt 153. After the second rotating shaft 152 rotates, the screw 151 will drive the moving assembly 6 to move left and right, thereby realizing the subsequent adjustment of the movement of the bulk material assembly 13, which facilitates the subsequent operation and use.

[0042] Working principle and usage process of this invention:

[0043] In operation, the operator first feeds quicklime into the working box 4 and the first rotating box 7 through the feed pipe 122. The quicklime then moves towards the center of the first rotating box 7 via the inclined inner wall. Next, the servo motor 101 is activated, which drives the second rotating box 8 to rotate inside the first rotating box 7 via the first rotating shaft 102. The second rotating box 8 disperses dust from the quicklime inside the first rotating box 7 and breaks up any lumpy quicklime. Simultaneously, the rotation of the first rotating shaft 102... The connecting belt 153 drives the second rotating shaft 152 and the screw 151 to rotate. When the screw 151 rotates, it will cause the moving component 6 and the bulk material component 13 to move together. The movement of the moving plate 61 will pull the second connecting shaft 132. The pulling of the second connecting shaft 132 will change the direction of the falling of the area between the two adjacent first movable plates 134 and second movable plates 135. As the quicklime moves downward from the inside of the first rotating box 7, the change of the bulk material component 13 will make the quicklime fall evenly into the bottom of the inner cavity of the processing box 1.

[0044] At the same time, when the moving plate 61 drives the pushing plate 62 to move, the pushing plate 62 will squeeze the contact plate 172. After being squeezed, the upper end of the contact plate 172 will flip around the roller 171 as the axis. At this time, the bottom end of the contact plate 172 will push the shaking frame 141. The shaking frame 141 will then push the quicklime a second time to prevent it from accumulating again.

[0045] Meanwhile, the device adopts an assembly design, which facilitates the cleaning of the inside of the first rotating box 7 and the processing box 1. At the same time, the bolts connecting the rotating baffle 2 and the processing box 1 will release the fixing effect between the baffle 2 and the processing box 1, thereby realizing the discharge of raw materials inside the processing box 1.
