Description

Technical Field

[0001] This invention relates to the field of coal gas purification equipment technology, specifically a blast furnace gas desulfurization device. Background Technology

[0002] As is well known, coal gas, as a clean fuel, is widely used in the ceramics, chemical, metallurgical, and alumina industries. Analysis of blast furnace gas from some steel enterprises reveals that it contains small amounts of chlorides and sulfides. Chlorides, when dissolved in water, are acidic and can corrode gas equipment and pipelines. Sulfides can be classified into two categories based on their chemical state: inorganic sulfides and organic sulfides. Organic sulfides, upon combustion, produce a large amount of SO2 as the final product, leading to excessive emissions from end-users such as hot blast stoves and heat treatment furnaces, worsening ambient air quality and endangering public health. Therefore, coal gas desulfurization devices are typically required when discharging coal gas.

[0003] A search revealed a Chinese patent with authorization number CN215560097U, which discloses a blast furnace gas desulfurization device. The device includes a desulfurization unit body, comprising a spray tower and a base. A solvent cylinder is connected to the spray tower via multiple support rods. A water tank is installed on the solvent cylinder, and a water pump is installed on the water tank. The output end of the water pump is connected to a water pipe. A spray pump is installed on the spray tower, and a spray pipe is connected to the spray pump.

Multiple branch pipes are connected to the diversion pipes, and baffles are connected to the branch pipes. Multiple nozzles are installed on the branch pipes. Multiple connecting rods are connected inside the spray tower, and demisters are installed on the connecting rods. A cleaning pump is installed on the spray tower, and a cleaning pipe is connected to the output end of the cleaning pump. Cleaning nozzles are installed on the cleaning pipe.

[0017] Compared with the prior art, the present invention provides a blast furnace gas desulfurization device, which has the following beneficial effects:

[0018] 1. This blast furnace gas desulfurization device, through the installation of cylinders, chutes, and sliding rods, allows for the pressure increase inside the blast furnace gas desulfurization tank and the top tank when maintenance or repair is required. This pressure is achieved by activating the cylinders, which in turn pressurize the sealing cavity and the chutes. The sliding rods, via the support columns, drive the top connecting plate and the top tank of the blast furnace gas desulfurization device upwards, raising the top tank from the top of the blast furnace gas desulfurization tank. This facilitates access for workers to the blast furnace gas desulfurization tank and the top tank through the gap between them, improving maintenance efficiency.

[0019] 2. This blast furnace gas desulfurization device, by installing a pressurizing device and a sliding block, can limit the sliding position of the slide bar, avoiding the trouble of the top tank of the blast furnace gas desulfurization device automatically sliding down when the cylinder is damaged or the internal pressure of the slide groove is released, thus enhancing safety.

[0020] 3. The blast furnace gas desulfurization device, by installing a venting device, allows the air pressure at the bottom of the sealing groove to be discharged through the venting groove when the sealing ring is inserted into the sealing groove. This avoids the problem of air being generated at the connection between the sealing ring and the sealing groove, which would lead to a decrease in the sealing performance of the sealing ring, and thus enhances the sealing performance.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below. 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.

[0031] Please see Figure 1-8A blast furnace gas desulfurization device includes a blast furnace gas desulfurization tank 1. A bottom connecting plate 2 is fixedly connected to the top of the blast furnace gas desulfurization tank 1. A top connecting plate 3 is attached to the top of the bottom connecting plate 2. A top blast furnace gas desulfurization tank 4 is fixedly connected to the top of the top connecting plate 3. Connecting columns 5 are fixedly connected at equal intervals to the outer surface of the blast furnace gas desulfurization tank 1. Support columns 6 are fixedly connected at equal intervals to the outer surface of the top connecting plate 3. A base 7 is fixedly connected to the bottom of the connecting columns 5. A sealing cavity 8 is opened inside the base 7. A cylinder 9 is fixedly installed inside the base 7. A sealing plate 10 is fixedly connected to the output end of the cylinder 9. Both the sealing cavity 8 and the sealing plate 10 are circular. A sealing ring is fixedly installed on the outer surface of the sealing plate 10, and the outer surface of the sealing plate 10 is slidably connected to the inside of the sealing cavity 8. The bottom of the base 7 has a venting groove 11 that communicates with the inside of the sealing cavity 8. The inside of the connecting column 5 has equidistant sliding grooves 12 that communicate with the inside of the sealing cavity 8. A sliding plate 13 is slidably connected to the inside of the sliding groove 12, and a sliding rod 14 is fixedly connected to the top of the sliding plate 13. A pressure boosting device 15 is fixedly installed on the outer surface of the connecting column 5. A limiting groove 16 is opened inside the connecting column 5, and a spring 161 is movably installed inside the limiting groove 16. The internal sealing sliding connection includes a sliding block 17, and a sealing gasket is fixedly installed on the outer surface of the sliding block 17. A toothed plate 18 is fixedly connected to the surface of the sliding block 17 away from the spring 161. The toothed plate 18 is a helical gear, and one end of the toothed plate 18 away from the sliding block 17 extends to the outer surface of the connecting post 5. A square sealing ring is fixedly installed on the outer surface of the sliding block 17. The surface of the slide bar 14 is provided with toothed grooves 141 that match the toothed plate 18 at equal intervals. The surface of the toothed plate 18 is meshed with the inside of the toothed grooves 141. A connecting pipe 19 that communicates with the inside of the limiting groove 16 is fixedly connected inside the connecting post 5. The cylinder 9, the slide groove 12, and the slide bar are installed. 14. When it is necessary to inspect or maintain the inside of the blast furnace gas desulfurization tank 1 and the blast furnace gas desulfurization top tank 4, the cylinder 9 can be activated to pressurize the sealing cavity 8 and the slide groove 12. This causes the slide bar 14 to slide upward through the support column 6, driving the top connecting plate 3 and the blast furnace gas desulfurization top tank 4 to rise from the top of the blast furnace gas desulfurization tank 1. This allows workers to enter the blast furnace gas desulfurization tank 1 and the blast furnace gas desulfurization top tank 4 through the gap between them for inspection and maintenance, thus improving maintenance efficiency.

[0032] The pressurization device 15 includes an outer cylinder 151 fixedly connected to the outer surface of the connecting column 5. An adjusting block 152 is slidably connected inside the outer cylinder 151. A servo motor 153 is fixedly installed inside the outer cylinder 151. A threaded rod 154 is fixedly connected to the output end of the servo motor 153. An annular sealing ring is fixedly installed on the outer surface of the adjusting block 152. A threaded hole matching the threaded rod 154 is opened at the center of the adjusting block 152. The outer surface of the threaded rod 154 is threadedly connected to the center of the adjusting block 152. Long grooves 155 are equidistantly opened inside the adjusting block 152. A long rod 156 is slidably connected inside the long grooves 155. An air passage groove 1561 is provided inside the 156. One end of the air passage groove 1561 extends to the outer surface of the long rod 156. The end of the long rod 156 away from the adjusting block 152 is fixedly connected to the inside of the outer cylinder 151. An air vent 157 communicating with the inside of the outer cylinder 151 is provided on the outer surface of the outer cylinder 151. The end of the connecting pipe 19 away from the limiting groove 16 is connected to the inside of the outer cylinder 151. By installing a pressurizing device 15 and a sliding block 17, the sliding position of the slide bar 14 can be limited, avoiding the trouble of the blast furnace gas desulfurization top tank 4 automatically sliding down when the cylinder 9 is damaged or the inside of the slide groove 12 is depressurized, thus enhancing safety.

[0033] The bottom connecting plate 2 has a sealing groove 21 at its top, and a sealing ring 31 matching the sealing groove 21 is fixedly connected to the bottom of the top connecting plate 3. The bottom of the bottom connecting plate 2 has an exhaust groove 22, the top of which is connected to the interior of the sealing groove 21. An air venting device 23 is installed inside the exhaust groove 22. The air venting device 23 includes a fixed panel 231 fixedly connected to the inner wall of the exhaust groove 22. A limiting cavity 232 is formed at the center of the fixed panel 231. A limiting block 233 is slidably connected inside the limiting cavity 232. A connecting rod 234 is fixedly connected to the bottom of the limiting block 233. An elastic plate 235 is movably sleeved on the outer surface of the connecting rod 234. The elastic plate 235 is a silicone plate. A sliding panel 236 is fixedly connected to the end of the connecting rod 234 away from the limiting block 233, which rests against the surface of the limiting block 233. The outer surface of the sliding panel 236 is slidably connected to the inside of the exhaust groove 22. A sealing plate is fixedly connected to the surface of the sliding panel 236 near the fixed panel 231. Exhaust holes 237 are equidistantly opened on the surface of the sliding panel 236, and vent holes 238 are equidistantly opened on the surface of the fixed panel 231. By installing the venting device 23, when the sealing ring 31 is inserted into the sealing groove 21, the air pressure at the bottom of the sealing groove 21 can be discharged through the exhaust groove 22, which can avoid the problem of air being generated at the connection between the sealing ring 31 and the sealing groove 21, which would lead to a decrease in the sealing performance of the sealing ring 31, and thus enhance the sealing performance.

[0034] In summary, when the internal maintenance of this blast furnace gas desulfurization device is required, the cylinder 9 is activated, which drives the sealing plate 10 to slide to the left. At this time, the air pressure inside the sealing cavity 8 increases, which in turn increases the air pressure inside the slide groove 12. This, in turn, drives the slide bar 14 to slide upward through the slide plate 13. The slide bar 14, through the support column 6, drives the top connecting plate 3 and the top tank 4 of the blast furnace gas desulfurization device to slide upward, thereby raising the top tank 4 of the blast furnace gas desulfurization device from the top of the blast furnace gas desulfurization tank body 1. This makes it easier for workers to enter the blast furnace gas desulfurization tank body 1 and the top tank 4 of the blast furnace gas desulfurization device through the gap between them for maintenance, thus improving maintenance efficiency.

[0035] When the top tank 4 of the blast furnace gas desulfurization system is raised to the appropriate position, the elasticity of the spring 161 and the air pressure inside the limiting groove 16 cause the sliding block 17 to drive the toothed plate 18 to slide, so that the surface of the toothed plate 18 is tightly engaged with the inside of the toothed groove 141. At this time, the position of the sliding rod 14 is positioned, which avoids the trouble of the top tank 4 of the blast furnace gas desulfurization system automatically sliding down when the cylinder 9 is damaged or the inside of the sliding groove 12 is depressurized, thus enhancing safety.

[0036] After maintenance is completed, the servo motor 153 is started first, which drives the threaded rod 154 to rotate, causing the adjusting block 152 to slide downwards. At this time, the top of the outer cylinder 151 is under negative pressure, and the limiting groove 16 is also under negative pressure through the connecting pipe 19. At this time, the sliding block 17 drives the toothed plate 18 to slide away from the sliding rod 14. At this time, the surface of the toothed plate 18 does not mesh with the inside of the toothed groove 141. Then, the cylinder 9 is started, which drives the sealing cavity 8 to slide in the opposite direction. At this time, the inside of the slide groove 12 slowly decreases. Due to the weight of the top tank 4 of the blast furnace gas desulfurization tank... Force is applied through the support column 6 and the slide bar 14 to drive the slide plate 13 to slide down slowly. When the bottom of the top connecting plate 3 is close to the top of the bottom connecting plate 2, the sealing ring 31 is inserted into the sealing groove 21. As the top connecting plate 3 continues to slide down, the air pressure at the bottom of the sealing groove 21 gradually increases, and the sliding panel 236 slides down through the exhaust groove 22 and the air passage 238. When the sliding panel 236 is not in contact with the surface of the fixed panel 231, the air pressure is discharged through the sliding panel 236, so that the surface of the sealing ring 31 can be sealed and adhered to the inner wall of the sealing groove 21.
