Description

Technical Field

[0001] This invention relates to the field of energy-saving technology, and in particular to an energy-saving device for smelting anode copper. Background Technology

[0002] In the process of copper anode smelting, the industry often recovers and utilizes the waste heat from the flue gas generated during the smelting process to achieve energy-saving goals. However, in actual recovery operations, the temperature of the flue gas just discharged is relatively high. If it is directly introduced into the waste heat recovery equipment, it is very easy to cause damage to the equipment due to overheating.

[0003] Currently, the cooling process is typically located between coarse and fine dust removal. A common industry practice is to extend the length of the flue gas duct, allowing the flue gas temperature to gradually decrease. However, this method results in a larger overall flue gas duct size, which increases equipment manufacturing costs and occupies more factory space, thus limiting site layout.

[0004] Another common method is water spraying for cooling. While this can shorten the flue length, the humidity of the flue gas increases significantly after it comes into contact with water vapor. Subsequent electrostatic precipitators or bag filters have specific requirements for flue gas humidity; if the humidity exceeds the standard, the dust removal efficiency will be affected. Therefore, an additional drying process is required, which not only extends the production process but may also incur additional costs and does not meet energy-saving goals. Summary of the Invention

Several embodiments of the invention are illustrated in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] Please see Figures 1 to 9 The image shows an energy-saving device for smelting anode copper according to an embodiment of the present invention, including a main pipe 10 for conveying high-temperature flue gas. The main pipe 10 includes a cooling pipe 11 and a high-temperature pipe 12 arranged in parallel. One end of the cooling pipe 11 and the high-temperature pipe 12 converges and connects to the air inlet pipe 13, and the other end converges and connects to the confluence pipe 14. A liquid spraying assembly 20 is disposed inside the cooling pipe 11 for spraying coolant to wet and cool the flue gas inside the cooling pipe 11. A liquid draining assembly 30 is disposed inside the cooling pipe 11 and located below the liquid spraying assembly 20 for draining the cooled coolant from the cooling pipe 11. The high-temperature flue gas flows in through the inlet pipe 13, then flows into the cooling pipe 11 and the high-temperature pipe 12 respectively, and finally converges into the confluence pipe 14 and flows out of the main pipe 10.

[0022] Understandably, by setting up a main pipe 10 to transport high-temperature flue gas, the flue gas enters the main pipe 10 through the inlet pipe 13. Part of the flue gas is diverted to the cooling pipe 11, where it is cooled by the coolant sprayed by the spray assembly 20, resulting in a decrease in temperature and an increase in humidity. Another part of the flue gas is diverted to the high-temperature pipe 12 without any treatment. Finally, the diverted flue gas merges in the confluence pipe 14, allowing the temperature and humidity of the two flue gas streams to neutralize and complement each other. Furthermore, the high-temperature gas discharged from the high-temperature pipe 12 further reduces the humidity of the neutralized gas, thus ensuring that the mixed flue gas meets the required temperature and humidity requirements, thereby reducing the impact on subsequent processes. Therefore, by reasonably controlling the temperature and humidity of the gas in both pipes, the merged flue gas meets the requirements without the need for additional pipe length or drying processes. This achieves low-cost pretreatment before flue gas energy-saving recovery, reducing costs and ensuring effectiveness for the overall flue gas energy-saving process. Therefore, the present invention solves the problem in the prior art of lacking an energy-saving device for anode copper smelting with a short flue length and suitable temperature and humidity of the cooled flue gas.

[0023] Specifically, the cooling pipe 11 has a first vent 111 at its outlet end, which is connected to the confluence pipe 14. A first control valve 15 is installed inside the first vent 111. Two parallel baffles 16 are installed at the bottom of the confluence pipe 14. The height of the baffles 16 is smaller than that of the first vent 111. A second vent 161 is installed on each of the two baffles 16, which is connected to the high-temperature pipe 12. A second control valve 17 is installed inside the second vent 161. The two baffles 16 and the confluence pipe 14 enclose a certain space 18. A first sensor is installed at the quantitative space 18 to detect the temperature inside the quantitative space 18. In practical implementation, to ensure the temperature and humidity of the mixed high-temperature gas and the cooled humid gas, accurate parameter control of the two gases is required. A quantitative space 18 is set to determine the volume of the mixed high-temperature gas and the volume determined by the first sensor. The flow rate and volume of the humid gas are determined by the first control valve 15 at the first air inlet, and the humidity of the humid gas is controlled by the drainage assembly 30. During execution, the first control valve 15 allows the humid gas to continuously flow into the confluence pipe 14, while the high-temperature gas accumulates and stores in the quantitative space 18. Once the quantitative space 18 is full, the volume and temperature parameters of the high-temperature gas are determined. This allows the required volume and flow rate of the humid gas to be determined in reverse. At this point, the quantitative space 18 is opened, allowing the high-temperature gas to flow into the confluence pipe 14. The first valve controls the inflow rate and volume of the subsequent humid gas, ensuring proper mixing of the two gases. Furthermore, due to the temperature of the humid gas and its high water density, its movement speed is relatively slow. This means that even if the humid gas flows into the confluence pipe 14 first, it can still be superimposed on the initially entering humid gas and mix with it when the high-temperature gas enters.

[0024] Additionally, a movable plate assembly 40 is provided both above and within the metering space 18. The movable plate assembly 40 includes a sealing frame 41, a hollow movable plate 42 mounted on the sealing frame 41, and a sliding plate 43 disposed within the movable plate 42. The movable plate 42 and the sliding plate 43 are respectively provided with mutually compatible first exhaust grooves 421 and second exhaust grooves 431. An impeller 44 is provided within the second exhaust groove 431. An electric push rod 45 is provided on one side of the movable plate 42 to push the sliding plate 43 to move within the movable plate 42. A second sensor is provided within the movable plate assembly 40 above the metering space 18 to detect the height of the movable plate assembly 40. Furthermore, in practical implementation, the temperature of the discharged high-temperature flue gas is usually not constant but fluctuates, resulting in uneven temperature distribution of the high-temperature gas within the metering space 18, making it difficult to accurately obtain temperature information and affecting the subsequent gas mixing effect. Furthermore, by setting up the movable plate assembly 40, initially, under the action of the electric actuator 45, the sliding plate 43 is moved relative to the movable plate 42, causing the first exhaust groove 421 and the second exhaust groove 431 to be misaligned, thus sealing the movable plate assembly 40. Under the push of the gas, the movable plate assembly 40 continues to move upward until it abuts against the upper baffle 16. Then, under the action of the electric actuator 45, the sliding plate 43 returns to its original position, the first exhaust groove 421 and the second exhaust groove 431 are aligned, and the movable plate assembly 40 moves downward. At this time, the impeller 44 inside the second exhaust rod rotates, stirring and mixing the gas in the metering space 18, ensuring a uniform temperature distribution within the metering space 18 and guaranteeing the accuracy of the temperature data. In addition, although the flow rate of the humidified air can be controlled by the first control valve 15 to adjust the volume of the humidified air, due to its continuous movement, it is still difficult to guarantee that the humidified air will not flow directly to the next process or travel too far, affecting the mixing effect. Furthermore, a movable plate assembly 40 is also installed here, allowing the humidified air to move the sealed movable plate assembly 40 upwards. The movable plate assembly 40 restricts the movement of the humidified air conditioner, preventing it from moving too far or escaping. A second sensor on the movable plate assembly 40 detects its height, accurately determining the volume of the humidified air in the mixing pipe, thus controlling and adjusting the subsequent inflow of humidified air. This ensures effective mixing of the two gases. During mixing, the movable plate assembly 40 changes to a non-sealed state, causing the impeller 44 to agitate the mixed gas, further improving and ensuring the mixing effect.

[0025] Specifically, a support frame 46 is provided inside the second exhaust trough 431. The impeller 44 is connected to the support frame 46 via a rotating shaft 441. A push plate 47 and a friction plate 48 are sequentially provided on the side of the sliding plate 43 away from the electric push rod 45. The push plate 47 and the friction plate 48 are connected by a first spring 49. An avoidance groove 432 is provided on the side of the sliding plate 43 near the friction plate 48 to allow the friction plate 48 to contact the main pipe 10. An interconnected movable space 433 is provided on the side of the sliding plate 43 near the friction plate 48 and in the support frame 46 near the friction plate 48. A connecting plate 434 is provided in the movable space 433. One end of the connecting plate 434 is connected to the push plate 47, and the other end is provided with a rack 435 that is adapted to the gear teeth 442 on the rotating shaft 441. In specific implementation, when the moving plate assembly 40 moves downward in an unsealed state and mixes and stirs the gas through the impeller 44, the moving speed of the moving plate assembly 40 will increase under the action of gravity. However, excessively fast moving speed will affect the stirring effect in the corresponding area. Therefore, by using the gear teeth 442 on the impeller shaft 441, the rotation of the impeller 44 will drive the gear teeth 442 to push the rack 435 to move, thereby pushing the connecting plate 434 to move towards the push plate 47. This pushes the push plate 47 to compress the first spring 49, and the first spring 49 then applies a spring force to the friction plate 48, causing the friction plate 48 to contact the inner wall of the main pipe 10. This increases the moving resistance of the moving plate 42, enabling the moving plate assembly 40 to move at a relatively uniform speed, thereby ensuring the gas mixing effect.

[0026] Furthermore, the rotating shaft 441 has a tooth 442 or multiple teeth 442 spaced at a preset distance. The rack 435 includes a first rack portion 4351 and a second rack portion 4352. The first rack portion 4351 and the second rack portion 4352 are spaced at a preset distance. The distance between the first rack portion 4351 and the friction plate 48 is smaller than that between the first rack portion 4352 and the second rack portion 4352. The bottom of the push plate 47 near the friction plate 48 is provided with a locking component 50. When the tooth 442 meshes with the second rack portion 4352, the locking component 50 is used to restrict the movement tendency of the push plate 47. In practical implementation, when the downward movement speed of the moving plate assembly 40 is slow, there is no need to apply resistance to the moving plate assembly 40 or apply a large amount of resistance. This will instead have a reverse effect on the moving speed of the moving plate assembly 40 and the rotation speed of the impeller 44, having the opposite effect on the mixing effect. That is, it is only necessary to apply greater resistance when the impeller 44 rotates very fast, that is, when the moving plate assembly 40 moves quickly. Then, by setting the first rack part 4351 and the second rack part 4352, when the impeller 44 rotates slowly, after a single tooth 442 or part of the teeth 442 applies action to the first rack part 4351, when the teeth 442 rotate back, the first rack part 4351 is also reset under the restoring force of the first spring 49. When the impeller 44 rotates... At a faster speed, when the gear tooth 442 rotates back, the first rack portion 4351 has not yet reset. At this time, the gear tooth 442 and the second rack portion 4352 drive the push plate 47 to move a greater distance, the friction plate 48 experiences greater pressure, and thus the resistance applied to the moving plate assembly 40 is greater. At this time, the push plate 47 is restricted by the locking member, thereby ensuring appropriate resistance to offset the acceleration trend of the moving plate assembly 40, so as to achieve a more uniform downward movement of the moving plate assembly 40. This avoids the push plate 47 moving back and forth, which would cause large fluctuations in the applied resistance. Consequently, when the moving plate assembly 40 moves at high speed, the speed fluctuations would also be large, resulting in significant differences in the residence time and mixing effect in different areas.

[0027] Furthermore, the locking assembly 50 includes a support base 51, a gear seat 52 mounted on the support base 51, and a vertical plate 53 mounted on one side of the gear seat 52. The gear seat 52 is slidably connected to the support base 51, and a second spring 54 is provided between the gear seat 52 and the support base 51. A one-way transmission rod 55 is provided on the vertical plate 53. The gear 56 on the gear seat 52 is rotatably connected to the gear seat 52 via connecting rods 561 on both sides. A rectangular block 562 is provided on the connecting rod 561 near the vertical plate 53. The bottom of the rectangular block 562 is slidably connected to the connecting rod 561 and is provided with a third spring 563. The end face of the one-way transmission rod 55 is provided with a rectangular groove 551 that is adapted to the rectangular block 562. The bottom of the connecting plate 434 near the push plate 47 is provided with a third rack 435 part 57 and a fourth rack 435 part 58 provided on the side of the third rack 435 part 57 away from the push plate 47. The height of the third rack 435 part 57 is higher than that of the fourth rack 435 part 58, and it is transitionally connected to the fourth rack 435 part 58. In practical implementation, when the gear tooth 442 meshes with the second rack portion 4352, the push gear 56 meshes with the third rack portion 57 and then with the fourth rack portion 58. Due to the height difference between the third rack portion 57 and the fourth rack portion 58, the gear seat 52 is pressed downwards, compressing the second spring 54. This causes the rectangular block 562 to embed into the rectangular groove 551 and compress the third spring 563. Consequently, under the action of the one-way transmission rod 55, the push plate 47 can only move towards the side closer to the friction plate 48, thus achieving a locking effect. Furthermore, this ensures that the friction force increases further when the speed of the moving plate assembly 40 changes rapidly. This further guarantees the uniform speed movement of the moving plate assembly 40.

[0028] Additionally, the activity space 433 is provided with a limiting groove 436 that passes through the sliding plate 43. The support base 51 is placed in the limiting groove 436 and is slidably connected to the limiting groove 436. The first exhaust groove 421 near the friction plate 48 is provided with an inclined surface 422. The inclined surface 422 is located on the side wall of the first exhaust groove 421 near the friction plate 48 and is inclined downward. After mixing, the moving plate assembly 40 moves to the bottom and stops. The sliding plate 43 moves under the action of the electric push rod 45, causing the first exhaust groove 421 and the second exhaust groove 431 to misalign. This causes the support base 51 to move away from the friction plate 48. At this time, the impeller 44 stops rotating, and the connecting plate 434 resets under the action of the first spring 49. When the support base 51 moves to the inclined plane 422, there is a space 433 below the support base 51. The first spring 49 then causes the connecting plate 434 to reset, allowing the fourth rack 435 58 to squeeze the wobbling gear 56 when it moves. The second spring 54 is compressed less due to the space below the support base 51 and cannot apply sufficient reverse squeezing force. This causes the fourth rack 435 58 to... The moving gear seat 52 is moved up and down, that is, the rectangular block 562 is pushed to slide out or in relative to the rectangular groove 551 repeatedly. It should be noted that, in specific implementation, due to the size of the fourth rack 435 part 58, it is not possible to apply enough displacement to make the rectangular block 562 slide out completely. After the fourth rack 435 part 58 has completely moved and reset, the third rack 435 part 57 is located above the gear 56 and is not engaged with the gear 56. Then, when the sliding plate 43 moves again and the first exhaust groove 421 and the second exhaust groove 431 are aligned, there is no longer an inclined surface 422 under the sliding seat. The compression of the second spring 54 increases, and enough force is applied to make the rectangular block 562 slide upward out of the rectangular groove 551, so that the gear 56 engages with the third rack 435 part 57, and the reset of the locking assembly 50 is completed.

[0029] Specifically, a limiting block 59 is provided on the outer side of the support base 51, and the outer diameter of the limiting block 59 is larger than that of the limiting groove 436. In a specific implementation, to prevent the support base 51 from falling off the inclined plane 422, the limiting block 59 is provided on the outer side of the support base 51.

[0030] Additionally, the liquid spraying assembly 20 includes multiple equidistantly distributed wetting grilles arranged from top to bottom. These wetting grilles are connected to an external liquid supply device and spray coolant into the cooling pipe 11. In practice, by setting multiple wetting grilles, coolant is applied to the flue gas in stages to improve the controllability of the cooling and wetting effect.

[0031] Specifically, the drain assembly 30 includes a conical guide shroud 31 and a drain pipe 32 at the bottom of the spray assembly 20. The cross-sectional area of ​​the guide shroud gradually increases from one side near the spray assembly 20 to the other. The drain pipe 32 is located on the side of the cooling pipe 11 at the bottom of the guide shroud and is used to drain the cooled coolant from the cooling pipe 11. In practical implementation, since the flue gas itself contains toxic components, the conical guide shroud 31 and drain pipe 32 are used to discharge the coolant containing the toxic components from the main pipe 10 for collection and harmless treatment. This also prevents the coolant from flowing into the intake pipe 13 and the high-temperature flue gas exhaust point. In addition, in practical implementation, an anti-corrosion layer needs to be installed on the inner part of the cooling pipe 11 to prevent corrosion from the coolant that has absorbed toxic substances.

[0032] In summary, this invention uses a main pipe 10 to transport high-temperature flue gas. The flue gas enters the main pipe 10 through the inlet pipe 13. Part of the flue gas is diverted to the cooling pipe 11, where it is cooled by the cooling liquid sprayed by the spraying component 20, resulting in a decrease in temperature and an increase in humidity. Another part of the flue gas is diverted to the high-temperature pipe 12 without any treatment. Finally, the diverted flue gas merges in the confluence pipe 14, allowing the temperature and humidity of the two flue gas streams to neutralize and complement each other. Furthermore, the high-temperature gas discharged from the high-temperature pipe 12 further reduces the humidity of the neutralized gas, thus ensuring that the mixed flue gas meets the required temperature and humidity requirements, thereby reducing the impact on subsequent processes. By rationally controlling the temperature and humidity of the gas in both pipes, the merged flue gas meets the requirements without the need for additional pipe length or drying processes. This achieves low-cost pretreatment before flue gas energy-saving recovery, reducing costs and ensuring effectiveness for the overall flue gas energy-saving process. Therefore, the present invention solves the problem in the prior art of lacking an energy-saving device for anode copper smelting with a short flue length and suitable temperature and humidity of the cooled flue gas.
