Description

Technical Field

[0001] This utility model relates to the field of blast furnace gas purification technology, specifically to an adsorption desulfurization reactor for blast furnace gas purification. Background Technology

[0002] Blast furnace gas is an important byproduct of the iron and steel metallurgical process. As a "symbiotic resource" of the iron and steel industry, its utilization level directly affects the industry's energy efficiency and environmental performance. Through efficient purification and rational application, it can not only reduce the energy costs of enterprises, but also promote the development of the iron and steel industry towards low carbon and circularity. Most existing technologies treat the gas by spraying desulfurizing agents, which react with the sulfides in the gas to achieve efficient removal.

[0003] However, the following drawbacks still exist: when spraying desulfurizing agent into coal gas, the spraying range is often limited, making it difficult for the coal gas to react with the desulfurizing agent. Some coal gas is discharged from the reactor without contacting the desulfurizing agent, affecting the desulfurization effect of the coal gas. In addition, the coal gas is transported quickly in the reactor, and the reaction time with the desulfurizing agent is limited, resulting in the inability to effectively separate sulfides in the coal gas. Utility Model Content

[0004] The purpose of this invention is to provide an adsorption desulfurization reactor for blast furnace gas purification, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adsorption desulfurization reactor for blast furnace gas purification, comprising a shell, an inlet pipe fixedly connected to the bottom of the shell, a plurality of outlets equally spaced on the outer wall of the inlet pipe, an outlet pipe fixedly connected to the top of the shell, two blocks symmetrically fixedly connected to the inner wall of the shell, the top and bottom of the blocks being inclined surfaces, a groove formed on one side of the shell, two first rotating shafts symmetrically rotatably connected to the inner wall of the shell and located inside the groove, a bracket fixedly connected to the outer wall of the first rotating shaft, a nozzle fixedly connected to one end of the bracket, a water pump fixedly connected to the bottom of the blocks, a pumping pipe fixedly connected to the output end of the water pump, a hose fixedly connected to the top of the pumping pipe, one end of the hose connected to the nozzle, and an adjustment assembly provided on the outer wall of the shell.

[0006] Preferably, the adjustment assembly includes a motor, which is fixedly mounted on the outer wall of the housing. The output end of the motor extends into the interior of the housing and is fixedly connected to a second rotating shaft. One end of the second rotating shaft is rotatably connected to the housing. A U-shaped frame is fixedly connected to the outer wall of the second rotating shaft. A connecting shaft is rotatably connected to the outer wall of the U-shaped frame. A rack is slidably connected to the inner wall of the groove. A gear is fixedly connected to the outer wall of the first rotating shaft. The gear meshes with the rack. The bottom of the connecting shaft extends into the interior of the groove and is rotatably connected to the rack. A through groove for use with the connecting shaft is provided inside the stop block.

[0007] Preferably, the inner wall of the housing is symmetrically fixedly connected to two fixing plates, the fixing plates are located between two stops, the inner wall of the fixing plates is slidably connected to two sliding shafts, the outer walls of the two sliding shafts are slidably connected to a lower pressure plate, the lower pressure plate is arc-shaped, the top of the two sliding shafts is fixedly connected to a limit plate, the outer wall of the sliding shafts is sleeved with a spring, the bottom of the spring is fixedly connected to the fixing plate, the top of the spring is fixedly connected to the lower pressure plate, and the outer wall of the second rotating shaft is provided with a linkage unit.

[0008] Preferably, the linkage unit includes an eccentric wheel, which is fixedly installed on the outer wall of the second rotating shaft, and the eccentric wheel is used in conjunction with the lower pressure plate.

[0009] Preferably, the top and bottom of the groove are both sloped.

[0010] Preferably, a baffle is fixedly connected to the top of the air intake pipe, and the top and bottom of the baffle are both set as annular inclined surfaces.

[0011] Preferably, a collar is fixedly connected to the top of the baffle, and a plurality of drainage grooves are equidistantly provided inside the collar.

[0012] Preferably, a water inlet pipe is fixedly connected to the outer wall of the shell.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By setting two baffles, the flow range of the gas is narrowed, so that the gas is concentrated between the two baffles. The motor controls the rack to move up and down back and forth. In cooperation with the gear, the spray head swings up and down back and forth, thereby increasing the coverage of the spray desulfurizing agent and improving the reaction effect with the gas.

[0015] 2. By setting a lower pressure plate to block the upward flow of coal gas, the coal gas is made to stay in the recess of the lower pressure plate. The rotation of the eccentric wheel and the spring make the lower pressure plate move up and down back and forth. The intermittent downward slapping of the lower pressure plate makes the coal gas after spraying flow downward again. This performs a second spraying of the coal gas after spraying, which avoids that some coal gas does not come into contact with the desulfurizing agent and prolongs the reaction time between the coal gas and the desulfurizing agent.

[0016] 3. The desulfurizing agent sprayed onto the object is collected through the groove. The desulfurizing agent slides down the slope at the bottom of the groove, thereby forming a desulfurizing agent water curtain at the bottom of the baffle, which reacts with the gas entering between the two baffles, thereby improving the desulfurization effect on the gas.

[0017] 4. Guided by the inclined surface at the bottom of the baffle, the coal gas discharged from the outlet flows downward and impacts the desulfurizing agent accumulated at the bottom of the shell, thereby pre-desulfurizing the coal gas that has not been sprayed. Through the obstruction of the collar, the desulfurizing agent falling from the spray accumulates at the inner angle between the baffle and the collar. When the liquid level of the desulfurizing agent reaches the drainage trough, it is discharged from several drainage troughs and slides down the inclined surface at the top of the baffle, thus forming an entire annular water curtain below the baffle. The coal gas discharged from the outlet needs to pass through the annular water curtain, thereby improving the desulfurization effect on the coal gas. Attached Figure Description

[0034] Please see Figures 1-5As shown, an adsorption desulfurization reactor for blast furnace gas purification includes a shell 1. An inlet pipe 2 is fixedly connected to the bottom of the shell 1. Several outlet ports 24 are equidistantly arranged on the outer wall of the inlet pipe 2. An outlet pipe 3 is fixedly connected to the top of the shell 1. Two baffles 4 are symmetrically fixedly connected to the inner wall of the shell 1. The top and bottom of the baffles 4 are both sloped. A groove 23 is formed on one side of the shell 1. Two first rotating shafts 5 are symmetrically rotatably connected to the inner wall of the shell 1 and located inside the groove 23. A bracket 6 is fixedly connected to the outer wall of the first rotating shaft 5. A nozzle 7 is fixedly connected to one end of the bracket 6. A water pump 8 is fixedly connected to the bottom of the baffles 4. A pumping pipe 9 is fixedly connected to the output end of the water pump 8. A flexible hose 10 is fixedly connected to the top of the pumping pipe 9. One end of the flexible hose 10 is connected to... The nozzle 7 is connected, and an adjustment assembly is provided on the outer wall of the housing 1. The adjustment assembly includes a motor 15, which is fixedly installed on the outer wall of the housing 1. The output end of the motor 15 extends into the interior of the housing 1 and is fixedly connected to a second rotating shaft 16. One end of the second rotating shaft 16 is rotatably connected to the housing 1. A U-shaped frame 14 is fixedly connected to the outer wall of the second rotating shaft 16. A connecting shaft 13 is rotatably connected to the outer wall of the U-shaped frame 14. A rack 12 is slidably connected to the inner wall of the groove 23. A gear 11 is fixedly connected to the outer wall of the first rotating shaft 5. The gear 11 meshes with the rack 12. The bottom of the connecting shaft 13 extends into the interior of the groove 23 and is rotatably connected to the rack 12. A through groove for use with the connecting shaft 13 is provided inside the stop block 4. A water inlet pipe 28 is fixedly connected to the outer wall of the housing 1.

[0035] During operation, desulfurizing agent is introduced into the shell 1 through the water inlet pipe 28, with the liquid level of the desulfurizing agent below the gas outlet 24. Gas is introduced into the shell 1 through the gas inlet pipe 2. Two baffles 4 are used to narrow the gas flow range, concentrating the gas flow between the two baffles 4. The water pump 8 is started, drawing the desulfurizing agent along the water pumping pipe 9 and hose 10 to the nozzle 7. The nozzle 7 sprays the gas flowing between the two baffles 4. Simultaneously with the spraying, the motor 15 is started, driving the second rotating shaft 16 to rotate, causing the U-shaped frame 14 to rotate. When the end of the U-shaped frame 14 rotates to the lower position, it pushes the connecting shaft 13 to move downward, causing the rack 12 to move downward, making the gear 11 rotate, and causing the nozzle 7 to swing upward. When the end of the U-shaped frame 14 rotates to the upper position, it pulls the connecting shaft 13 to move upward, causing the rack 12 to move upward, making the gear 11 rotate, and causing the nozzle 7 to swing downward. This process repeats itself. As the motor 15 starts, it drives the nozzle 7 to swing up and down repeatedly, thereby increasing the coverage of the sprayed desulfurizing agent and improving the reaction effect with the coal gas. The sprayed coal gas is discharged from the casing 1 through the gas outlet pipe 3.

[0036] Furthermore, two fixing plates 17 are symmetrically fixedly connected to the inner wall of the housing 1. The fixing plates 17 are located between the two stops 4. Two sliding shafts 18 are slidably connected to the inner wall of the fixing plates 17. A lower pressure plate 21 is slidably connected to the outer wall of the two sliding shafts 18. The lower pressure plate 21 is arc-shaped. A limit plate 20 is fixedly connected to the top of the two sliding shafts 18. A spring 19 is sleeved on the outer wall of the sliding shafts 18. The bottom of the spring 19 is fixedly connected to the fixing plate 17, and the top of the spring 19 is fixedly connected to the lower pressure plate 21. A linkage unit is provided on the outer wall of the second rotating shaft 16. The linkage unit includes an eccentric wheel 22, which is fixedly installed on the outer wall of the second rotating shaft 16. The eccentric wheel 22 works in conjunction with the lower pressure plate 21.

[0037] During operation, the gas continues to flow upward after being sprayed. The upward-flowing gas is blocked by the lower pressure plate 21, causing the gas to stay in the recess of the lower pressure plate 21. As the second rotating shaft 16 rotates, it drives the eccentric wheel 22 to rotate. When the protruding end of the eccentric wheel 22 rotates to the lower position, it pushes the lower pressure plate 21 to move downward and compresses the spring 19. When the protruding end of the eccentric wheel 22 rotates to the upper position, it pushes the lower pressure plate 21 to move upward under the action of the spring 19. This process is repeated. As the eccentric wheel 22 rotates, it drives the lower pressure plate 21 to move up and down back and forth. Through the intermittent downward patting of the lower pressure plate 21, the gas after spraying is transmitted downward again. This performs a secondary spraying of the gas after spraying, preventing some gas from not contacting the desulfurizing agent and prolonging the reaction time between the gas and the desulfurizing agent.

[0038] Furthermore, both the top and bottom of the groove 23 are set as slopes;

[0039] During operation, the desulfurizing agent sprayed from nozzle 7 falls into the opposite groove 23 and slides down along the slope at the bottom of groove 23, thereby forming a desulfurizing agent water curtain at the bottom of baffle 4, which reacts with the gas entering between the two baffles 4, thereby improving the desulfurization effect on the gas.

[0040] Furthermore, a baffle 25 is fixedly connected to the top of the air intake pipe 2, and both the top and bottom of the baffle 25 are set as annular slopes;

[0041] During operation, when the gas is discharged into the shell 1 from the outlet 24, it is guided by the inclined surface at the bottom of the baffle 25, causing the gas to flow downward and impact the desulfurizing agent stored at the bottom of the shell 1, thereby pre-desulfurizing the gas that has not been sprayed.

[0042] Furthermore, a collar 26 is fixedly connected to the top of the baffle 25, and a number of drainage grooves 27 are equidistantly provided inside the collar 26.

[0043] During operation, some of the desulfurizing agent sprayed from the nozzle 7 falls onto the top of the baffle 25. Through the obstruction of the collar 26, the desulfurizing agent accumulates at the inner angle between the baffle 25 and the collar 26. When the liquid level of the desulfurizing agent reaches the drainage trough 27, it is discharged from several drainage troughs 27 and slides down the slope at the top of the baffle 25, thus forming an entire annular water curtain below the baffle 25. The gas discharged from the gas outlet 24 needs to pass through the annular water curtain, thereby improving the desulfurization effect on the gas.

[0044] Working principle: Desulfurizing agent is introduced into the shell 1 through the water inlet pipe 28. The liquid level of the desulfurizing agent is below the gas outlet 24. Coal gas is introduced into the shell 1 through the gas inlet pipe 2. When the coal gas is discharged into the shell 1 from the gas outlet 24, it is guided by the inclined surface at the bottom of the baffle 25, causing the coal gas to flow downward and impact the desulfurizing agent accumulated at the bottom of the shell 1. This pre-desulfurizes the coal gas that has not been sprayed. The two baffles 4 are set to narrow the flow range of the coal gas, so that the coal gas flows between the two baffles 4. The water pump 8 is started to draw the desulfurizing agent along the water pumping pipe 9 and the hose 10 to the nozzle 7. The nozzle 7 sprays the coal gas flowing between the two baffles 4. When the nozzle 7 sprays, the motor 15 is started. The motor 15 drives the second rotating shaft 16 to rotate, causing the U-shaped frame 14 to rotate. When the end of the U-shaped frame 14 rotates to the lower position, it pushes the connecting shaft 13 to move downward, causing the rack 12 to move downward, which in turn causes the gear 11 to rotate, causing the nozzle 7 to swing upward. When the end of the U-shaped frame 14 rotates to the upper position, it pulls the connecting shaft 13 to move upward, causing the rack 12 to move upward, which in turn causes the gear 11 to rotate, causing the nozzle 7 to swing downward. This process repeats itself. As the motor 15 starts, it drives the nozzle 7 to swing up and down repeatedly, thereby increasing the coverage of the sprayed desulfurizing agent and improving the reaction effect with the coal gas. The desulfurizing agent sprayed from the nozzle 7 falls into the opposite groove 23 and slides downward along the slope at the bottom of the groove 23, thus reaching the bottom of the stop block 4. A desulfurizing agent water curtain is formed, reacting with the gas entering between the two baffles 4, thereby improving the desulfurization effect on the gas. Part of the desulfurizing agent sprayed from the nozzles 7 falls onto the top of the baffle 25. Blocked by the collar 26, the desulfurizing agent accumulates at the inner angle between the baffle 25 and the collar 26. When the liquid level of the desulfurizing agent reaches the drainage troughs 27, it is discharged from several drainage troughs 27 and slides down the slope of the top of the baffle 25, thus forming a complete annular water curtain below the baffle 25. The gas discharged from the outlet 24 needs to pass through this annular water curtain, thereby improving the desulfurization effect on the gas. After being sprayed, the gas continues to flow upwards. The downward pressure plate 21 blocks the upward flow of gas, causing it to flow downwards... The pressure plate 21 stays in the recess. As the second rotating shaft 16 rotates, it drives the eccentric wheel 22 to rotate. When the protruding end of the eccentric wheel 22 rotates to the lower position, it pushes the lower pressure plate 21 to move downward and compresses the spring 19. When the protruding end of the eccentric wheel 22 rotates to the upper position, it pushes the lower pressure plate 21 to move upward under the action of the spring 19. This process is repeated. As the eccentric wheel 22 rotates, it drives the lower pressure plate 21 to move up and down back and forth. Through the intermittent downward patting of the lower pressure plate 21, the gas after spraying is transmitted downward again. This performs a second spraying on the gas after spraying, which avoids some gas not coming into contact with the desulfurizer and prolongs the reaction time between the gas and the desulfurizer. The gas after spraying is discharged from the gas outlet pipe 3 and discharged from the shell 1.
