Description

Technical Field

[0001] This invention relates to the field of sintering machine technology, specifically to a device for purifying flue gas from a sintering machine. Background Technology

[0002] Sintering machines are key pieces of equipment in the metallurgical industry used for sintering ores (such as iron ore). They are mainly used to heat powdery or fine-grained raw materials (such as mineral powder, recycled ore, flux, fuel, etc.) at high temperatures to produce sinter with a certain strength and particle size for use in blast furnace ironmaking. When sintering limestone, a sintering machine is used for the sintering operation. The flue gas discharged from the sintering machine's exhaust pipe needs to be purified by a purification device to avoid causing external air pollution.

[0003] A search revealed a Chinese patent with application number "CN202411540730.0", which specifically describes a device for purifying flue gas from a sintering machine. The device includes a desulfurization tower body, an installation frame fixedly connected to the inner side of the tower body, a hollow rotating column rotatably connected to the top of the installation frame, a rotating disk fixedly connected to the top of the hollow rotating column, a connecting rod fixedly connected to the outer side of the rotating disk, an outlet pipe fixedly connected to the top of both the connecting rod and the rotating disk, a blocking component fixedly connected to the top of both the connecting rod and the rotating disk, and a flue gas inlet pipe fixedly connected to the bottom of the installation frame.

[0004] In the original patented technology, the purification of sintering machine flue gas was carried out by spraying alkaline solutions (such as NaOH or Ca(OH)2 solutions). When high-concentration flue gas directly enters the purification device, due to the lack of effective flow equalization measures, the flue gas velocity and concentration are unevenly distributed in the tower, resulting in insufficient residence time of flue gas in some areas, which affects the desulfurization and deacidification efficiency. Due to the turbulent flue gas flow field, some high-temperature flue gas fails to fully contact the spray liquid, resulting in excessively high local temperatures, which affects the chemical reaction efficiency. Summary of the Invention

The flue gas is discharged through the upper opening of the branch cylinder 710 and further dispersed by dispersing plate 714 to make the flue gas distribution uniform. Rotating rod 10 drives stirring plate 711 to rotate. Stirring plate 711 further disperses the flue gas discharged from branch cylinder 710 to facilitate uniform distribution of flue gas.

The coolant is then discharged into the purification cylinder 1 through the third annular pipe 755 and the outlet pipe 756, which facilitates the cooling of the high-temperature flue gas by the multiple cooling pipes 754.

[0039] Example 2

[0040] Based on Example 1, such as Figures 7-9As shown, an activated carbon plate 8 is fixedly connected to the outer side of the fixed cylinder 73. The uniform assembly 74 includes a fixing ring 741, which is fixedly connected to the outer side of the fixed cylinder 73 and located above the activated carbon plate 8. A sliding groove 742 is provided on the outer side of the fixing ring 741. Multiple guide blocks 743 are slidably connected to the inner side of the sliding groove 742. A fixing block 744 is fixedly connected to the outer side of each of the multiple guide blocks 743. An inclined plate 745 is rotatably connected to the outer side of the fixing block 744. The upper side of the inclined plate 745 is fixed. A fixed block 746 is connected to the outside of the fixed block 746, and a control plate 747 is rotatably connected to the outside of the rotating rod 10. A guide plate 7410 is fixedly connected to the outside of the guide plate 7410, and a lifting block 7411 is slidably connected to the outside of the guide plate 7410. A connecting block 7412 is fixedly connected to the outside of the lifting block 7411, and a lifting ring 749 is fixedly connected to the outside of the connecting block 7412. Multiple fixed blocks 748 are fixedly connected to the outside of the lifting ring 749, and the fixed blocks 748 are rotatably connected to the control plate 747. A mounting plate 7414 is fixedly connected to the outer side of the fixed plate 10. A spring 7413 is fixedly connected between the mounting plate 7414 and the connecting block 7412. A stop rod 7415 is fixedly connected to the upper side of the lifting ring 749. Multiple protrusions 17 are fixedly connected to the lower side of the fixed plate 11. The stop rod 7415 abuts against the protrusions 17. When treating the flue gas, the rotating rod 10 drives the lifting ring 749 to rotate. The lifting ring 749 drives the inclined plate 745 on the control plate 747. At the same time, the lifting ring 749 drives the stop rod 7415. When the nozzle 15 rotates, the push rod 7415 moves up and down repeatedly under the action of the protrusion 17. The push rod 7415 drives the lifting ring 749 to move up and down repeatedly. The lifting ring 749 drives the control plate 747 to swing. The control plate 747 drives the inclined plate 745 to swing, so that multiple inclined plates 745 can rotate and swing at the same time, so that the inclined plates 745 can disperse the liquid discharged from the nozzle 15, so that the impurities when the liquid and flue gas are mixed are evenly distributed on the activated carbon plate 8, which facilitates the treatment of impurities in the flue gas.

[0041] Working principle: In operation, the operator first connects the air inlet pipe 2 to the flue gas outlet of the sintering machine. The flue gas is then introduced into multiple branch cylinders 710 through multiple branch pipes 79. The motor 5 is started, which drives the rotating rod 10 to rotate. Under the action of the base frame 712, gear ring 713, gear 717, and rotating shaft 716, the dispersing plate 718 is controlled to rotate, facilitating the initial dispersion of the flue gas by the dispersing plate 718 and dispersing holes 719. Then, the flue gas is further dispersed through the second dispersing plate 714. The rotating rod 10 drives the stirring plate 711 to rotate, which disperses the discharged flue gas. The flue gas is then discharged through the top pipe 76. At the same time, the water pump 6 is started, causing the nozzle 15 to spray out. An alkaline solution facilitates the treatment of flue gas. Simultaneously, the rotating rod 10 drives the lifting ring 749 to rotate, which in turn drives the abutment rod 7415 to rotate. Under the action of the protrusion 17, spring 7413, lifting block 7411, and control plate 747, multiple inclined plates 745 are controlled to rotate and swing simultaneously, making it convenient for the inclined plates 745 to disperse the falling liquid, so that impurities in the flue gas are evenly distributed on the activated carbon plate 8, increasing the purification effect. During treatment, water pump 2 751 is started, and the installation pipe 752, annular pipe 2 753, cooling pipe 754, and water outlet pipe 756 are connected to facilitate the cooling pipe 754 to cool the high-temperature flue gas, preventing the exhaust flue gas temperature from being too high and polluting the surrounding environment.
