Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, and in particular to a device for removing thallium from regenerated copper flue gas desulfurization wastewater. Background Art

[0002] The raw materials used in the smelting production of recycled copper are very complex and contain toxic raw materials. Some of these toxic raw materials contain thallium, which results in the flue gas produced during the recycled copper smelting process containing heavy metal pollutants thallium and its compounds. During the desulfurization treatment of the flue gas, thallium in the desulfurization circulating slurry will be enriched with the running time. Therefore, people often use desulfurization wastewater thallium removal equipment to remove thallium from the desulfurization circulating slurry.

[0003] Patent publication number CN221296606U discloses a wastewater thallium removal device, including a sedimentation tank, a grid plate is vertically installed in the middle of the sedimentation tank, a stirring tank is provided on one side of the sedimentation tank, a filter tank is provided on one side of the stirring tank, a plurality of vertical S-shaped spoilers are installed inside the sedimentation tank on one side of the grid plate, a first water pump is provided on one side of the interior of the sedimentation tank, a first connecting pipe is installed at the liquid outlet end of the first water pump, and the outer end of the first connecting pipe is connected to the upper part of the stirring tank; a second water pump is provided at the bottom of one side of the stirring tank, a second connecting pipe is connected to the liquid outlet end of the second water pump, and the outer end of the second connecting pipe is connected to the upper part of the filter tank; a stirring mechanism is provided inside the other side of the stirring tank.

[0004] The above device transports the sewage to be treated to the sedimentation tank through the water inlet pipe. Under the action of the grid plate, the larger impurities that are difficult to dissolve in water are blocked on the water inlet side. The first water pump is started to discharge the sewage after preliminary filtration from the sedimentation tank to the stirring tank. After adding thallium removal agent to the sewage, the thallium removal agent reacts with thallium in the sewage to produce precipitates that are difficult to dissolve in water. After a period of precipitation, the second water pump is started to transport the clean water to the filter tank. Under the action of the filter membrane, the impurities containing thallium in the water are further removed. Finally, the clean water is discharged through the discharge valve pipe. In the above device, When sewage passes through the S-shaped spoiler, the speed of sewage passing through the grid plate will be reduced due to the disturbing effect of the S-shaped spoiler. When sewage passes through the S-shaped spoiler, some impurities will be blocked by the S-shaped spoiler, resulting in residual impurities on the S-shaped spoiler, which will cause the disturbing effect of the S-shaped spoiler to weaken. Therefore, the S-shaped spoiler needs to be cleaned frequently, and the equipment needs to be shut down before cleaning, which leads to a decrease in work efficiency and is very time-consuming and labor-intensive. Therefore, a regenerated copper flue gas desulfurization wastewater thallium removal device that can automatically clean the guide plate is designed. Summary of the invention

[0045] If people need to remove thallium from the desulfurization wastewater of regenerated copper flue gas, they can use this device to operate. First, people push the baffle 101 forward so that the baffle 101 blocks the bottom of the first reaction box 1 to prevent the sewage from flowing out from the lower side of the first reaction box 1 when the first reaction box 1 is working. Then people inject a certain amount of desulfurization wastewater that needs to be treated for thallium removal into the first reaction box 1 through the feed pipe 13. After the desulfurization wastewater passes through the guide plate 12, the speed of the desulfurization wastewater will decrease, so that the speed of the desulfurization wastewater passing through the first screening element 14 will be slowed down. At the same time, the guide plate 12 can preliminarily block the impurities in the desulfurization wastewater. Then the desulfurization wastewater passes through the first screening element 14, so that the impurities in the desulfurization wastewater are further blocked. Impurities will remain on the left side of the first screening element 14, and the desulfurized wastewater that passes through will pass through the first screening element 14. Then people turn on the middle water pump 17 through the control console 11, and the filtered desulfurized wastewater will be pumped in by the middle water pump 17. When all the desulfurized wastewater enters the second reaction box 111, people turn off the middle water pump 17 through the control console 11, and put the thallium removal agent into the second reaction box 111, and then start the first motor 15. The output shaft of the first motor 15 drives the stirring element 16 to rotate, so that the desulfurized wastewater and the thallium removal agent are fully mixed and reacted, and the thallium element in the desulfurized wastewater reacts with the thallium removal agent to produce precipitation, thereby achieving the effect of removing thallium from the desulfurized wastewater. Under the screening action of the second screening element 110, the thallium-containing precipitate will The desulfurized wastewater 100 will remain on the left side of the second screening element 110, while the desulfurized wastewater after thallium removal will pass through. When the desulfurized wastewater in the second reaction box 111 has completely reacted, people will then control the water pump 17 on the right to start through the console 11 to discharge the desulfurized wastewater after thallium removal. When the desulfurized wastewater has been completely desulfurized, people will move the baffle 101 backward to make the impurities in the first reaction box 1 fall into the receiving box 2. At the same time, the electric push rod 21 will be started through the console 11 to make the telescopic end of the electric push rod 21 extend to the lower left, and the electric push rod 21 will drive the push frame 22 to move toward the lower left. The push frame 22 will first contact and squeeze the first extrusion member 25, and the first extrusion member 25 will be squeezed to move to the right, and the first extrusion member 25 will drive the first blocking member 24 to move to the lower left. The push rod 23 moves to the lower left, and the first spring 27 is stretched, so that the first blocking member 24 no longer blocks the push rod 23. The push rod 23 moves to the lower left due to its own gravity. Then people control the telescopic end of the electric push rod 21 to retract through the console 11. The electric push rod 21 drives the pushing frame 22 to move to the upper right and reset. When the first extrusion members 25 are separated from the pushing frame 22, the first spring 27 is reset and drives the first blocking member 24 to move to the left and reset. The first blocking member 24 drives the first extrusion member 25 to move to the left and reset. The push rod 23 drives the first blocking member 24 to move to the lower left. The push rod 23 pushes the impurities attached to the guide plate 12 to the lower left, so that the impurities attached to the guide plate 12 fall into the receiving box 2. When the cleaning is completed,Then people manually drive the push rod 23 to move to the upper right to reset, and pull the first blocking member 24 to the right, and the first spring 27 is stretched. When the push rod 23 is reset, people release the first blocking member 24, and the first spring 27 is reset to drive the first blocking member 24 to move to the left to reset, so that the first blocking member 24 blocks the push rod 23. Then people open the door of the receiving box 2, and then clean up the impurities and sediments in the receiving box 2 and the second reaction box 111, and finally close the door of the receiving box 2. In the above operation, people control the electric push rod 21 through the console 11 to drive the push frame 22 to move toward the lower left, and the push frame 22 squeezes the first extrusion member 25, so that the first extrusion member 25 drives the first blocking member 24 to move to the right, and the first blocking member 24 no longer resists the push rod 23. The push rod 23 moves toward the lower left due to its own gravity, so that the push rod 23 removes the impurities attached to the guide plate 12, thereby avoiding the problem of poor turbulence effect of the guide plate 12 due to the residual impurities on the guide plate 12.

[0046] Example 2: Based on Example 1, please refer to Figure 8-Figure 11 , and also includes a scraping mechanism capable of cleaning the gaps between the guide plates 12, the scraping mechanism includes three squeezing plates 34, the squeezing plates 34 are fixedly connected to the portion of the push rod 23 located inside the first reaction box 1, the squeezing plates 34 and the guide plates 12 are squeezed together, three holes are opened on the squeezing plates 34, a third screening member 33 is fixed on the left side of the squeezing plates 34, a one-way valve 31 is fixed on the right side of the hole position on the squeezing plates 34, so that sewage can pass through in one direction, and a rotating component that allows the push rod 23 to rotate is connected to the push rod 23.

[0047] See also Figure 8 and Fig. 9 The rotating assembly includes three first gears 3, which are respectively fixedly connected to the front parts of different push rods 23, and three first racks 32 are fixed to the lower side of the pushing frame 22, and the first racks 32 are meshed with the corresponding first gears 3.

[0048] When cleaning the guide plate 12, impurities may remain in the gaps between the guide plates 12 and cannot be removed, so a scraping mechanism is provided, and its working principle is as follows: when removing impurities from the guide plate 12, the control console 11 controls the electric push rod 21 to drive the pushing frame 22 to move to the lower left, and the pushing frame 22 drives the first rack 32 to move to the lower left, and the first rack 32 and the corresponding first gear 3 are meshed with each other, so that the first gear 3 starts to rotate counterclockwise, and the first gear 3 drives the pushing rod 23 to start rotating counterclockwise, and the pushing rod 23 drives the extrusion plate 34 and then drives the third screening member 33 to rotate counterclockwise, so that the extrusion plate 34 drives the third screening member 33 to rotate counterclockwise to a horizontal state, and at this time the extrusion plate 34 is located on the upper side of the guide plate 12. The first blocking member 24 is pushed to the left and the first blocking member 24 is pushed to the right and the first blocking member 24 is pushed to the right and the first blocking member 24 is pushed to the left and the first spring 27 is stretched, and the pushing frame 22 continues to move toward the lower left, and the pushing rod 23 drives the pushing rod 23 to move toward the lower left. When the pushing frame 22 is disengaged from the first extruding member 25, the first spring 27 is reset to drive the first blocking member 24 to move to the left and reset, and the first blocking member 24 drives the first extruding member 25 to move to the left and reset, and the pushing rod 23 drives the extrusion plate 34 and then drives the third screening member 33 to move toward the lower left. At this time, the third screening member 33 is located in the gap between the guide plates 12, and the third screening member 33 moves to the lower left, so that the third screening member 33 The sieve 33 squeezes the impurities in the gap and drives the impurities to move to the lower left. At the same time, under the filtering effect of the third sieve 33 and the one-way valve 31, the water contained in the impurities is squeezed out, so as to reduce the consumption of desulfurization wastewater. When the water is squeezed out, people pull the baffle 101 backwards, and at the same time, the squeezing plate 34 drives the third sieve 33 to continue to move to the lower left, so that all the impurities are pushed into the receiving box 2. When all the impurities are cleared, people control the telescopic end of the electric push rod 21 to retract through the console 11, and the electric push rod 21 drives the push frame 22 and then drives the first rack 32 to move to the upper right and reset. At this time, the third sieve 33 is located in the gap between the guide plates 12. Because the guide plates 12 are all inclined, the squeezing plate 34 will be on the left The guide plate 12 is blocked, so that the extrusion plate 34 cannot rotate clockwise, thereby making the first rack 32 drive the first gear 3 and then drive the pushing rod 23 to move to the upper right and reset, the pushing rod 23 drives the extrusion plate 34 and then drives the third screening member 33 to move to the upper right and reset, when the pushing rod 23 moves to the uppermost side of the slide slot, the pushing frame 22 first contacts and squeezes the first extrusion member 25, so that the first extrusion member 25 drives the first blocking member 24 to move to the right, the first spring 27 is stretched, the pushing frame 22 drives the first rack 32 and then drives the first gear 3 to move to the upper right, the first gear 3 drives the pushing rod 23 and then drives the extrusion plate 34 to continue to move to the upper right, when the pushing frame 22 and the first extrusion member 25 are disengaged,The first spring 27 is reset to drive the first blocking member 24 to move to the left and reset, and the first blocking member 24 drives the first extruding member 25 to move to the left and reset, so that the first extruding member 25 continues to resist the push rod 23. When the extrusion plate 34 moves to the upper edge of the guide plate 12, the guide plate 12 no longer blocks and restricts the extrusion plate 34. The first rack 32 is meshed with the first gear 3, so that when the first rack 32 moves to the upper right, it drives the first gear 3 to rotate clockwise. The first gear 3 drives the push rod 23 and then drives the extrusion plate 34 to rotate clockwise and reset. Finally, people put the material receiving box 2 in The impurities are cleaned up. The above operation drives the first rack 32 to move to the lower left through the push frame 22. The first rack 32 meshes with the first gear 3, so that the first gear 3 rotates counterclockwise. The first gear 3 drives the push rod 23 and then drives the extrusion plate 34 to rotate counterclockwise.
