Description

Technical Field

[0001] The present invention relates to the technical field of flue gas desulfurization, and particularly to a sintering flue gas desulfurization device. Background Art

[0002] In the steel production process, a large amount of flue gas containing sulfur dioxide is generated in the sintering process. The sintering flue gas desulfurization device aims to remove sulfur dioxide from such flue gas, reduce its pollution to the atmosphere, help steel enterprises achieve green and sustainable development, and strictly meet the national environmental protection standards.

[0003] Common sintering flue gas desulfurization devices are composed of an absorption tower, a desulfurizing agent supply system, a flue gas reheater, a demister and a control system, etc. When working, the sulfur-containing flue gas enters from the bottom of the absorption tower and comes into full contact with the desulfurizing agent (such as lime slurry) sprayed down from the top of the tower. Sulfur dioxide reacts chemically with the desulfurizing agent to form sulfite, which is partially oxidized to form sulfate. The desulfurized flue gas is dehumidified by the demister, heated up by the flue gas reheater, and then discharged into the atmosphere through the chimney.

[0004] However, in the actual use process of the above equipment, the existing spray system and flue gas of the desulfurization device result in a small contact area and short contact time between the limestone slurry and the flue gas, and the sulfur in the flue gas cannot react fully with the limestone, so that the desulfurized flue gas still contains a high concentration of sulfur, which is difficult to meet the increasingly strict environmental protection standards. This not only reduces the desulfurization efficiency, but also increases the energy consumption and operating cost of the equipment. In view of this, we have proposed a sintering flue gas desulfurization device. Summary of the Invention

[0020] Compared with the prior art, the present invention provides a sintering flue gas desulfurization device, which has the following beneficial effects:

[0021] 1. For this sintering flue gas desulfurization device, in order to improve the desulfurization efficiency of the desulfurization device, a purification component is provided. This component cooperates with the limestone slurry pipe on the desulfurization tower to convey the slurry to the slurry conveying pipe. Multiple groups of spray pipes increase the spraying area of the limestone slurry. The flue gas introduced through the inlet flue pipe generates a swirling upward airflow under the action of the spiral spoiler, prolonging the contact time between the flue gas and the limestone slurry, increasing the contact area between the two, enhancing the desulfurization reaction effect. The demister is arranged below the outlet flue pipe to effectively remove the water mist in the desulfurized flue gas and ensure that the discharged flue gas meets the standards.

[0022] 2. In order to reduce equipment failures caused by blockages in this sintering flue gas desulfurization device, a protective component is provided. This component, in cooperation with the sliding grooves and cylindrical grooves on the desulfurization tower, provides sliding tracks for the round rod and slider. The long spring pushes the round rod, causing the slider to drive the funnel plate to slide stably. The arc-shaped round block on the square tube fixes the dredging spikes. As the square tube rotates, multiple groups of dredging spikes are always located directly below the conical holes and conical grooves. When a blockage occurs, the liquid flow in the filter cartridge becomes unsmooth, which drives the round plate to descend, enabling the dredging spikes to pierce into the conical holes and conical grooves, thereby timely cleaning the blockages in the conical holes and conical grooves.

[0023] 3. In order to further improve the performance of this sintering flue gas desulfurization device, an auxiliary component is provided. This component, in cooperation with the motor on the chamfered round block, drives the large gear to rotate. The large gear meshes with multiple groups of small gears, causing multiple groups of thin rods and stirring turbines to rotate. Multiple groups of stirring turbines stir the slurry at the bottom of the desulfurization tower, preventing the slurry from settling, promoting the full reaction of limestone with sulfur in the flue gas, improving the desulfurization efficiency. The top of the thin rod fits against the bottom of the arc-shaped round block, and while stirring, it assists to a certain extent in the cleaning work of the dredging spikes on the conical holes and conical grooves.

[0024] 4. In order to ensure the stable operation of this sintering flue gas desulfurization device, a cleaning component is provided. This component, in cooperation with the round-headed vertical rod, fixes the cylinder. The short spring pushes the straight rod, causing the straight scraper to fit against the inner surface of the filter cartridge and the inclined scraper to fit against the inner surface of the funnel plate. As the round plate rotates, multiple groups of straight scrapers and inclined scrapers can timely remove the impurities attached to the inner surfaces of the filter cartridge and the funnel plate, preventing the accumulation of impurities from affecting the filtration effect.

For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to specific circumstances.

[0040] Please refer to Figure 1 - Figure 12 , the present invention provides a technical solution:

[0041] A sintering flue gas desulfurization device, comprising a desulfurization tower 1, a smoke inlet pipe 2 is fixedly installed on the desulfurization tower 1, a smoke outlet pipe 3 is fixedly installed above the desulfurization tower 1, and a base 4 is fixedly installed at the bottom of the desulfurization tower 1. Before the device is started, the desulfurization tower 1 is firmly fixed by relying on the base 4 to ensure the overall stability of the device.

[0042] In an embodiment of the present invention, a purification component 5 is provided on the desulfurization tower 1. The purification component 5 includes a limestone slurry pipe 51. One end of the limestone slurry pipe 51 is fixedly installed on the desulfurization tower 1. The other end of the limestone slurry pipe 51 is fixedly installed with one end of a slurry conveying pipe 52. The other end of the slurry conveying pipe 52 is fixedly installed with a spray pipe 53. A spiral flow deflector 54 is fixedly installed inside the desulfurization tower 1. A demister 55 is fixedly installed inside the desulfurization tower 1. One end of a funnel plate 56 is slidably installed inside the desulfurization tower 1. The other end of the funnel plate 56 is fixedly installed with one end of a filter cartridge 57. The other end of the filter cartridge 57 is fixedly installed with a circular plate 58. A conical hole 59 is formed in the circular plate 58. A conical groove 510 is formed in the circular plate 58. A chamfered circular block 511 is fixedly installed at the bottom inside the desulfurization tower 1. A motor 512 is fixedly installed inside the chamfered circular block 511. One end of a square rod 513 is fixedly installed at the output end of the motor 512. The other end of the square rod 513 is fixedly installed with a square tube 514. One end of a spiral spring 515 is fixedly installed inside the square tube 514. The other end of the spiral spring 515 is fixedly installed with one end of a square mounting rod 516. The other end of the square mounting rod 516 is fixedly installed at the bottom of the circular plate 58. A circular ring tube 517 is fixedly installed at the bottom inside the desulfurization tower 1. A square hole 518 is formed in the circular ring tube 517. One end of a square connecting pipe 519 is fixedly installed on the circular ring tube 517. A slurry suction pipe 520 is fixedly installed on the desulfurization tower 1. Multiple groups of spray pipes 53, conical holes 59, conical grooves 510 and square holes 518 are provided. The multiple groups of conical holes 59 are spatially connected to the conical grooves 510. The large hole direction of the conical groove 510 is arranged above the circular plate 58. The multiple groups of spray pipes 53 increase the spraying area of the limestone slurry and improve the desulfurization efficiency. The upward design of the large hole of the conical groove 510 facilitates the collection and guidance of the desulfurized liquid. The demister 55 is arranged below the smoke outlet pipe 3. The slurry conveying pipe 52 and the multiple groups of spray pipes 53 are arranged below the demister 55. The spiral flow deflector 54 is arranged below the slurry conveying pipe 52 and the multiple groups of spray pipes 53. The smoke inlet pipe 2 is arranged below the spiral flow deflector 54. The funnel plate 56 is arranged below the smoke inlet pipe 2. The bottom open end of the spiral flow deflector 54 is far from the smoke inlet pipe 2. The internal spaces of the circular ring tube 517 and the square connecting pipe 519 are connected. The other end of the square connecting pipe 519 is connected to the internal space of the slurry suction pipe 520. The spiral flow deflector 54 is made of stainless steel. Through a special spiral structure, a swirling upward air flow is generated in the desulfurization tower 1 for the flue gas, increasing the contact time and area between the flue gas and the limestone slurry.

[0043] During the use of this embodiment, after the device is started, the sintering flue gas surges into the desulfurization tower 1 from the flue gas inlet pipe 2. At the same time, the purification component 5 starts to operate. The limestone slurry flows into the slurry delivery pipe 52 through the limestone slurry pipe 51 and is then distributed to multiple groups of spray pipes 53. The multiple groups of spray pipes 53 greatly expand the spraying area of the limestone slurry, making the limestone slurry evenly dispersed in the desulfurization tower 1. Under the action of the spiral turbulence plate 54, the flue gas introduced by the flue gas inlet pipe 2 forms a rotating upward airflow in the desulfurization tower 1. Its unique spiral structure greatly extends the contact time between the flue gas and the limestone slurry and significantly increases the contact area between the two. During this process, sulfur in the flue gas fully reacts with the sprayed limestone slurry to achieve desulfurization, effectively reducing the sulfur content in the flue gas. The flue gas after the desulfurization reaction continues to rise and reaches the demister 55 below the flue gas outlet pipe 3. The demister 55 can efficiently remove the water mist in the desulfurized flue gas, ensuring that the finally discharged flue gas meets the environmental protection standards and is discharged through the flue gas outlet pipe 3. The desulfurized liquid then flows downward. The funnel plate 56 plays a preliminary guiding role for the liquid. Subsequently, the liquid enters the filter cartridge 57. The filter cartridge 57 and the circular plate 58 finely filter the desulfurized liquid. The multiple groups of conical holes 59 and conical grooves 510 on the circular plate 58 guide the liquid to flow orderly, enabling the liquid to smoothly flow to the bottom of the desulfurization tower 1. At the bottom of the desulfurization tower 1, the desulfurized liquid flows into the square connecting pipe 519 through the square hole 518 on the circular tube 517. The square connecting pipe 519 is connected to the internal space of the slurry suction pipe 520. The slurry suction pipe 520 is connected to an external slurry suction pump. The liquid is then discharged from the desulfurization tower 1 through the external slurry suction pump by the slurry suction pipe 520, completing the collection and treatment of the desulfurized slurry.

[0044] In an embodiment of the present invention, a protection component 6 is provided on the desulfurization tower 1. The protection component 6 includes a sliding groove 61. A sliding groove 61 is formed on the desulfurization tower 1. A cylindrical groove 62 is formed on the desulfurization tower 1. One end of a long spring 63 is fixedly installed inside the desulfurization tower 1. The other end of the long spring 63 is fixedly installed with one end of a round rod 64. The other end of the round rod 64 is fixedly installed with one end of a slider 65. The other end of the slider 65 is fixedly installed on the outer surface of the funnel plate 56. An arc-shaped round block 66 is fixedly installed on the square tube 514. A dredging thorn 67 is fixedly installed on the arc-shaped round block 66. Multiple groups of the sliding groove 61, cylindrical groove 62, long spring 63, round rod 64, slider 65 and dredging thorn 67 are provided. The arc-shaped round block 66 and the dredging thorn 67 are arranged below the circular plate 58. Multiple groups of dredging thorns 67 are arranged directly below the conical holes 59 and conical grooves 510, so as to facilitate the cleaning of the blockages in the conical holes 59 and conical grooves 510. The long spring 63 is arranged inside the cylindrical groove 62. The round rod 64 slides inside the cylindrical groove 62. The slider 65 slides inside the sliding groove 61, thus ensuring the stable sliding of the funnel plate 56, being convenient for installation and maintenance, and providing a limit.

[0045] During the use of this embodiment, the protection component 6 and the purification component 5 work synchronously. The sliding groove 61 and the cylindrical groove 62 on the desulfurization tower 1 construct a sliding track for the round rod 64 and the slider 65, and restrict the funnel plate 56. The long spring 63 inside the cylindrical groove 62 continuously exerts force to push the round rod 64, and then the slider 65 drives the funnel plate 56 to slide stably, ensuring that the funnel plate 56 is always in a suitable working position. The arc-shaped round block 66 and the dredging thorn 67 fixed on the square tube 514, the motor 512 drives the square rod 513 and the square tube 514 to rotate slowly continuously, so that multiple groups of dredging thorns 67 are always located directly below the conical hole 59 and the conical groove 510. When the filter cartridge 57 is blocked and the liquid flow is obstructed, the round plate 58 will move downward under the action of the liquid pressure, driving the dredging thorn 67 to accurately pierce into the conical hole 59 and the conical groove 510, and timely cleaning the blockage therein, avoiding the influence of blockage on the discharge and filtration of the desulfurized liquid, and effectively reducing equipment failures caused by blockage.

[0046] In an embodiment of the present invention, an auxiliary component 7 is provided on the chamfered round block 511. The auxiliary component 7 includes an installation groove 71. The installation groove 71 is opened on the chamfered round block 511. The output end of the motor 512 is fixedly installed with a large gear 72. A thin rod 73 is rotatably installed on the chamfered round block 511. A small gear 74 is fixedly installed on the thin rod 73. A stirring turbine 75 is fixedly installed on the thin rod 73. Multiple groups of the thin rod 73, the small gear 74 and the stirring turbine 75 are provided. Multiple groups of small gears 74 are engaged with the large gear 72. The large gear 72 and multiple groups of small gears 74 are arranged inside the installation groove 71. The top end of the thin rod 73 abuts against the bottom of the arc-shaped round block 66. Multiple groups of stirring turbines 75 further enhance the stirring effect.

[0047] During the use of this embodiment, during the operation of the device, the auxiliary component 7 starts to play a role. The motor 512 on the chamfered round block 511 drives the large gear 72 to rotate. The large gear 72 meshes with multiple groups of small gears 74. The small gears 74 are fixed on the thin rod 73, and then drive multiple groups of thin rods 73 and stirring turbines 75 to rotate at an accelerated speed. Multiple groups of stirring turbines 75 fully stir the slurry at the bottom of the desulfurization tower 1, effectively preventing the slurry from precipitating, promoting the more sufficient reaction between limestone and sulfur in the flue gas, and further improving the desulfurization efficiency. The top end of the thin rod 73 abuts against the bottom of the arc-shaped round block 66. During the stirring process, it provides certain assistance for the cleaning work of the dredging thorn 67 on the conical hole 59 and the conical groove 510, ensuring the high efficiency and stability of the entire desulfurization process, and further improving the performance of the desulfurization device.

[0048] In an embodiment of the present invention, a cleaning assembly 8 is provided on the circular plate 58. The cleaning assembly 8 includes a round-headed vertical rod 81. A cylinder 82 is fixedly installed on the round-headed vertical rod 81. One end of a short spring 83 is fixedly installed inside the cylinder 82. The other end of the short spring 83 is fixedly installed with a straight rod 84. The other end of the straight rod 84 is fixedly installed with a straight scraper 85. An inclined scraper 86 is fixedly installed above the straight scraper 85. There are multiple groups of the round-headed vertical rod 81, the cylinder 82, the short spring 83, the straight rod 84, the straight scraper 85, and the inclined scraper 86. The straight rod 84 slides inside the cylinder 82. The straight scraper 85 fits against the inner surface of the filter cylinder 57. The inclined scraper 86 fits against the inner surface of the funnel plate 56. The round-headed vertical rod 81 and the straight scraper 85 are not provided with dredging thorns 67. The fitting design of multiple groups of straight scrapers 85 and inclined scrapers 86 can effectively remove the attached impurities and avoid interference with the dredging thorns 67.

[0049] When this embodiment is in use, the cleaning assembly 8 works synchronously during the operation of the device. Inside the cylinder 82 fixed to the round-headed vertical rod 81, the short spring 83 pushes the straight rod 84, so that the straight scraper 85 closely fits against the inner surface of the filter cylinder 57, and the inclined scraper 86 closely fits against the inner surface of the funnel plate 56. As the circular plate 58 rotates, multiple groups of straight scrapers 85 and inclined scrapers 86 rotate synchronously, which can timely remove the impurities attached inside the filter cylinder 57 and the funnel plate 56, preventing the accumulation of impurities from affecting the filtration effect. The fitting design of the straight scraper 85 and the inclined scraper 86 can effectively remove impurities while avoiding interference with the dredging thorns 67, ensuring the stable operation of the desulfurization device.
