Description

Technical Field

[0001] This invention relates to the field of flue gas desulfurization technology, specifically to a flue gas desulfurization device for an all-oxygen combustion glass melting furnace. Background Technology

[0002] The glass industry is a key sector for air pollution control, with its main pollutant emissions coming from glass melting furnace flue gas. This flue gas contains high concentrations of sulfur dioxide and a large amount of highly viscous dust. If these pollutants are emitted directly without treatment, they will cause serious air pollution. To meet increasingly stringent environmental regulations and reduce sulfur dioxide emissions from glass melting furnace flue gas, flue gas desulfurization technology is particularly important. Flue gas desulfurization technology can effectively convert sulfur dioxide in flue gas into easily treatable compounds, thereby reducing its environmental pollution.

[0003] Currently, the main method for flue gas desulfurization is to pass flue gas into a desulfurization tower, and then spray calcium hydroxide solution into the tower. The calcium hydroxide solvent reacts chemically with the sulfur dioxide in the flue gas to generate easily treatable and pollution-free salts, thereby desulfurizing the sulfur dioxide in the flue gas. However, in the current desulfurization process, it is not possible to achieve sufficient contact and reaction between the sulfur dioxide in the flue gas and the calcium hydroxide solvent. As a result, some sulfur dioxide is not treated, leading to poor treatment effect and causing environmental pollution problems. Summary of the Invention

[0015] The beneficial effects of this invention are:

[0016] (1) Flue gas is supplied into the purification chamber, and then atomized calcium hydroxide solution is sprayed into the purification chamber to ensure that sulfur dioxide in the flue gas and calcium hydroxide solvent are fully contacted and reacted. At the same time, the drive shaft drives the drive screw to rotate, disturbing the airflow in the purification chamber, further promoting the full mixing and contact of flue gas and calcium hydroxide solvent. During the spraying process, the electric telescopic rod drives the extrusion plate to squeeze the gas in the purification chamber towards the center, increasing the pressure in the purification chamber, accelerating the flow of calcium hydroxide solvent and oxygen, and promoting a more complete reaction, thereby achieving efficient purification and removal of sulfur dioxide in the flue gas.

[0017] (2) A metering pump is used to pump water from the outside into the pulping tank. Combined with the feed screw driven by the drive motor, the amount of calcium hydroxide powder added can be precisely controlled according to the concentration of sulfur dioxide in the flue gas, so as to achieve precise automatic pulping. The second rotating shaft uses a stirring rod and a stirring plate to fully stir and mix the calcium hydroxide powder and water in the pulping tank, so as to ensure that a uniform and high-quality calcium hydroxide solvent is obtained, which provides a good foundation for the subsequent desulfurization process. Because the ratio of calcium hydroxide solvent can be precisely controlled, it can also flexibly adapt to flue gas with different sulfur concentrations to achieve full desulfurization and purification. At the same time, the entire pulping and desulfurization process is highly automated. From pulping and mixing to feeding, no manual intervention is required, which greatly improves work efficiency and operation convenience.

[0018] (3) The first extrusion plate is moved by the first electric telescopic rod. The first extrusion plate scrapes the reacted salts and settled dust adhering to the inner wall of the purification chamber, pushing them to the discharge trough. Then, the second drive shaft is rotated by the second drive motor. The second drive shaft rotates the air inlet pipe through the first drive gear and the second drive gear. The air inlet pipe rotates the scraper. The scraper scrapes the waste scraped off the first extrusion plate. Then, the scraper block is moved upward by the second electric telescopic rod. Then, the scraper block is rotated so that the scraper block is perpendicular to the ground and adheres to the scraper block. Then, the scraper block is moved downward by the second electric telescopic rod. The scraper block scrapes the waste on the scraper block, thereby realizing the automatic cleaning and removal of the reacted salts and settled dust in the purification chamber without manual cleaning, further improving the efficiency of flue gas desulfurization.

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.

[0027] Example 1

[0028] Please see Figures 1-5 As shown, the present invention is a desulfurization device for flue gas from an all-oxygen combustion glass melting furnace, including an installation plate 1. Multiple purification boxes 2 are fixedly connected to the top of the installation plate 1. A first extrusion plate 3 is slidably connected inside the purification box 2. An air inlet mechanism is provided on the first extrusion plate 3. The air inlet mechanism is used to purify the sulfides in the flue gas by slidably connecting a second extrusion plate 4 inside the purification box 2. The second extrusion plate 4 is provided with a desulfurization and purification mechanism. The desulfurization and purification mechanism is used to purify the sulfides in the flue gas. A transmission column 5 is fixedly connected to the side of the first extrusion plate 3 and the second extrusion plate 4 that are far apart from each other. One end of the transmission column 5 is fixedly connected to a first electric telescopic rod 6 that is fixedly connected to the purification box 2 through a connecting block.

[0029] A slurry preparation device is fixedly connected to the top of the mounting plate 1. The slurry preparation device is used to supply desulfurization slurry to the desulfurization purification device.

[0030] By connecting the flue gas to the air intake mechanism on each purification box 2 through a pipeline, the flue gas enters the purification box 2 through the air intake mechanism. Then, the desulfurization and purification device on the second extrusion plate 4 sprays atomized calcium hydroxide solution into the purification box 2, so that the atomized calcium hydroxide solution is fully mixed with the sulfides in the flue gas. At the same time, the first electric telescopic rod 6 drives the transmission column 5 to move, and the transmission column 5 drives the first extrusion plate 3 and the second extrusion plate 4 to move in the purification box 2, applying extrusion to the purification box 2, thereby further promoting the full mixing and contact of sulfur dioxide in the flue gas with calcium hydroxide, so that calcium hydroxide dissolves and reacts fully with the sulfides, removing sulfur dioxide from the flue gas, greatly improving the removal effect of sulfur dioxide in the flue gas.

[0031] Example 2

[0032] Based on Example 1, please refer to Figure 1 , Figure 3 and Figure 4As shown, the air intake mechanism includes an air intake pipe 11 rotatably connected to the first extrusion plate 3. One end of the air intake pipe 11 is rotatably connected to a first connecting pipe 12 fixedly connected to the first extrusion plate 3. An electromagnetic valve 13 is provided on the first connecting pipe 12. Multiple elastic airbags 14 are fixedly connected to the first connecting pipe 12. A one-way air valve 15 is provided on the first connecting pipe 12. A discharge mechanism connected to the purification box 2 is provided on the air intake pipe 11.

[0033] The desulfurization and purification mechanism includes multiple transmission pipes 21 rotatably connected to the second extrusion plate 4. One end of the transmission pipe 21 is fixedly connected to an atomizing nozzle 22. A transmission shaft 23 is rotatably connected to the second extrusion plate 4. A first gear 24 is fixedly sleeved on the outer surface of the transmission shaft 23. A second gear 25, which is fixedly sleeved on the outer surface of the first gear 24, is meshed with the transmission pipe 21. A transmission screw rod 26 is fixedly connected to one end of the transmission shaft 23. A first drive mechanism connected to the first extrusion plate 3 is driven to one end of the transmission shaft 23. The first drive mechanism is used to drive the transmission shaft 23 to rotate. A connecting ring pipe 27 connected to the second extrusion plate 4 is rotatably connected to one end of the transmission pipe 21. One end of the connecting ring pipe 27 is connected to the pulping device on the mounting plate 1 through a hose.

[0034] The first drive mechanism includes a first drive motor 31 fixedly connected to the second extrusion plate 4. The first drive motor 31 is controlled by a PLC programming program, which can control the first drive motor 31 to rotate forward and backward and rotate at different angles. The output end of the first drive motor 31 is fixedly connected to a first drive shaft 32 fixedly connected to the transmission shaft 23 via a coupling.

[0035] The first drive motor 31 drives the first drive shaft 32 to rotate, and the first drive shaft 32 drives the transmission shaft 23 to rotate.

[0036] Flue gas is supplied into the first connecting pipe 12, and then enters the inlet pipe 11 through the first connecting pipe 12. After a period of time, the solenoid valve 13 on the first connecting pipe 12 closes, and the purification box 2 is completely sealed. At this time, due to continuous external exhaust, gas is supplied to the first connecting pipe 12. The gas then enters the elastic air bladder 14 on the first connecting pipe 12 through the one-way air valve 15 for gas storage, so that the external flue gas can be continuously exhausted. At this time, the pulping device supplies pulp to the hose, and the hose transmits power through the connecting coil 27. Calcium hydroxide slurry is supplied through pipe 21, and then the atomized calcium hydroxide solution is sprayed out through the atomizing nozzle 22. Simultaneously, the first drive mechanism drives the drive shaft 23 to rotate. The drive shaft 23, through the first gear 24 and the second gear 25, drives the drive pipe 21 to rotate, which in turn drives the atomizing nozzle 22 to rotate, ensuring that the atomizing nozzle 22 thoroughly sprays the atomized calcium hydroxide solvent into the purification chamber 2. At the same time, the drive shaft 23 drives the drive screw 26 to rotate, disturbing the airflow within the purification chamber 2, thereby promoting the purification chamber 2... The flue gas inside the purification chamber 2 comes into full contact with the calcium hydroxide solvent. Simultaneously, during the spraying process, the first electric telescopic rod 6 moves the transmission column 5, thereby causing the first extrusion plate 3 and the second extrusion plate 4 to compress the gas inside the purification chamber 2 towards the center, increasing the pressure inside the purification chamber 2. This accelerates the flow of the atomized calcium hydroxide solvent and oxygen within the purification chamber 2, promoting a complete reaction between the calcium hydroxide solvent and sulfur dioxide in the flue gas. After the reaction is complete, the first electric telescopic rod 6 moves the transmission column 5, which in turn moves the second extrusion plate 4, opening it. The discharge mechanism discharges the purified flue gas and simultaneously moves the first extrusion plate 3 to discharge the salts formed after the reaction and the atomized dust, achieving automatic discharge. Then, it moves the first extrusion plate 3 and the second extrusion plate 4 back to their initial positions. At this time, the solenoid valve 13 is opened, and the flue gas in the elastic airbag 14 enters the purification chamber 2 under pressure. Then, the solenoid valve 13 is closed, and the purification chamber 2 undergoes a purification reaction. This process is repeated to achieve thorough purification and removal of sulfur dioxide in the flue gas, greatly improving the desulfurization effect of the flue gas.

[0037] Example 3

[0038] Based on Example 2, please refer to Figure 2 and Figure 5As shown, the pulping device includes a pulping tank 41 fixedly connected to the mounting plate 1. A drive motor 42 is fixedly connected to one side of the pulping tank 41. The drive motor 42 is controlled by a PLC programming program, which can control the forward and reverse rotation and rotation angle of the drive motor 42. The output end of the drive motor 42 is fixedly connected to a first rotating shaft 43 through a coupling. The outer surface of the first rotating shaft 43 is driven by a drive wheel and a drive belt to a second rotating shaft 44 rotatably connected to the pulping tank 41. One end of the second rotating shaft 44 is fixedly connected to a stirring rod 45 rotatably connected to the pulping tank 41. Multiple stirring plates 46 are fixedly connected to the outer surface of the stirring rod 45. A metering pump 47 is fixedly connected to the mounting plate 1. The output end of the metering pump 47 is fixedly connected to a water supply pipe 48. A feed pump 49 is fixedly connected to one side of the pulping tank 41 through a pipe. The output end of the feed pump 49 is fixedly connected to a second connecting pipe 490 fixedly connected to a hose through a pipe. A feeding mechanism connected to the pulping tank 41 is driven by the outer surface of the first rotating shaft 43.

[0039] The feeding mechanism includes a feeding box 51 fixedly connected to the pulping box 41, a feeding pipe 52 fixedly connected to the bottom of the feeding box 51, and a feeding screw 53 fixedly connected to the first rotating shaft 43 rotatably connected inside the feeding pipe 52.

[0040] A metering pump 47 pumps a measured amount of external water into the pulping tank 41. Then, a drive motor 42 drives a first rotating shaft 43 to rotate, which in turn drives a feeding screw 53. Simultaneously, the amount of calcium hydroxide powder added is precisely controlled according to the concentration of sulfur dioxide in the flue gas. The number of rotations of the feeding screw 53 is precisely controlled to precisely control the amount of calcium hydroxide powder added to the pulping tank 41, ensuring a measured amount is fed. After feeding is complete, the drive motor 42 reverses its rotation, and the feeding screw 53 stops feeding. At this point, the first rotating shaft 43 drives a second rotating shaft 41 via a drive belt and a drive wheel. The rotating shaft 44 rotates, and the second rotating shaft 44 thoroughly mixes the calcium hydroxide powder and water in the slurry tank 41 through the stirring rod 45 and the stirring plate 46 to obtain calcium hydroxide solvent. Then, the calcium hydroxide solvent is pumped into the second connecting pipe 490 through the feed pump 49 and the pipeline. Subsequently, the second connecting pipe 490 feeds the connecting coil pipe 27 through the hose, thereby realizing precise automatic slurry preparation of desulfurization calcium hydroxide solvent. This allows the slurry to fully desulfurize and purify flue gas with different sulfur concentrations, while also improving the automation level of desulfurization and further improving the efficiency of flue gas desulfurization.

[0041] Example 4

[0042] Based on Example 2, please refer to Figure 3 and Figure 4As shown, the discharge mechanism includes a scraper 61 fixedly connected to the air inlet pipe 11, a second drive motor 62 fixedly connected to one side of the first extrusion plate 3, a second drive shaft 63 fixedly connected to the output end of the second drive motor 62 via a coupling, a first drive gear 64 fixedly sleeved on the outer surface of the second drive shaft 63, a second drive gear 65 fixedly sleeved on the outer surface of the first drive gear 64, and a discharge trough 68 opened on the purification box 2. A scraping mechanism slidably connected to the scraper 61 is provided on the top of the mounting plate 1.

[0043] The scraping mechanism includes a second electric telescopic rod 66 fixedly connected to the mounting plate 1, and a scraper block 67 slidably connected to the scraper 61 is fixedly connected to one end of the second electric telescopic rod 66.

[0044] After the flue gas is purified, the first electric telescopic rod 6 drives the first extrusion plate 3 to move. The first extrusion plate 3 scrapes the reacted salts and settled dust adhering to the inner wall of the purification chamber 2, pushing them to the discharge trough 68. Then, the second drive motor 62 drives the second drive shaft 63 to rotate. The second drive shaft 63 drives the air inlet pipe 11 to rotate through the first drive gear 64 and the second drive gear 65. The air inlet pipe 11 drives the scraper 61 to rotate. The scraper 61 scrapes the waste scraped off the first extrusion plate 3. Then, the second electric telescopic rod 66 drives the scraper block 67 to move upward, which in turn drives the scraper 61 to rotate, making the scraper 61 perpendicular to the ground and in contact with the scraper block 67. Then, the second electric telescopic rod 66 drives the scraper block 67 to move downward, and the scraper block 67 scrapes the waste off the scraper 61. This achieves automatic cleaning and removal of the reacted salts and settled dust in the purification chamber 2 without manual cleaning, further improving the efficiency of flue gas desulfurization.

[0045] The working principle of this invention is as follows: Flue gas is supplied into the first connecting pipe 12, and then the flue gas enters the air inlet pipe 11 through the first connecting pipe 12. After a period of air intake, the solenoid valve 13 on the first connecting pipe 12 closes, and the purification box 2 is completely sealed. At this time, due to continuous external exhaust, air is supplied to the first connecting pipe 12. The gas then enters the elastic air bladder 14 on the first connecting pipe 12 through the one-way air valve 15 for storage, allowing the external flue gas to be continuously exhausted. At this time, the pulping device supplies pulp to the hose, and the hose is connected to the connecting ring. Pipe 27 supplies calcium hydroxide slurry to transmission pipe 21, which then sprays atomized calcium hydroxide solution through atomizing nozzle 22. Simultaneously, the first drive mechanism drives the transmission shaft 23 to rotate. The transmission shaft 23, through the first gear 24 and the second gear 25, drives the transmission pipe 21 to rotate, which in turn drives the atomizing nozzle 22 to rotate, ensuring that the atomizing nozzle 22 thoroughly sprays atomized calcium hydroxide solvent into the purification chamber 2. Simultaneously, the transmission shaft 23 drives the transmission screw 26 to rotate, disturbing the airflow within the purification chamber 2, thereby promoting… The flue gas inside the purification chamber 2 comes into full contact with the calcium hydroxide solvent. Simultaneously, during the spraying process, the first electric telescopic rod 6 moves the transmission column 5, thereby causing the first extrusion plate 3 and the second extrusion plate 4 to compress the gas inside the purification chamber 2 towards the center, increasing the pressure inside the purification chamber 2. This accelerates the flow of the atomized calcium hydroxide solvent and oxygen within the purification chamber 2, promoting a complete reaction between the calcium hydroxide solvent and sulfur dioxide in the flue gas. After the reaction is complete, the first electric telescopic rod 6 moves the transmission column 5, which in turn moves the second extrusion plate 4, causing... When the discharge mechanism is opened, the purified flue gas is discharged, which simultaneously moves the first extrusion plate 3 to discharge the salts formed after the reaction and the atomized dust, thus achieving automatic discharge. Then, the first extrusion plate 3 and the second extrusion plate 4 are moved back to their initial positions. At this time, the solenoid valve 13 is opened, and the flue gas in the elastic airbag 14 enters the purification chamber 2 under pressure. Then, the solenoid valve 13 is closed, and the purification chamber 2 undergoes a purification reaction. This process is repeated to achieve thorough purification and removal of sulfur dioxide in the flue gas, greatly improving the desulfurization effect of the flue gas.

[0046] A metering pump 47 pumps a measured amount of external water into the pulping tank 41. Then, a drive motor 42 drives a first rotating shaft 43 to rotate, which in turn drives a feeding screw 53. Simultaneously, the amount of calcium hydroxide powder added is precisely controlled according to the concentration of sulfur dioxide in the flue gas. The number of rotations of the feeding screw 53 is precisely controlled to precisely control the amount of calcium hydroxide powder added to the pulping tank 41, ensuring a measured amount is fed. After feeding is complete, the drive motor 42 reverses its rotation, and the feeding screw 53 stops feeding. At this point, the first rotating shaft 43 drives a second rotating shaft 41 via a drive belt and a drive wheel. The rotating shaft 44 rotates, and the second rotating shaft 44 thoroughly mixes the calcium hydroxide powder and water in the slurry tank 41 through the stirring rod 45 and the stirring plate 46 to obtain calcium hydroxide solvent. Then, the calcium hydroxide solvent is pumped into the second connecting pipe 490 through the feed pump 49 and the pipeline. Subsequently, the second connecting pipe 490 feeds the connecting coil pipe 27 through the hose, thereby realizing precise automatic slurry preparation of desulfurization calcium hydroxide solvent. This allows the slurry to fully desulfurize and purify flue gas with different sulfur concentrations, while also improving the automation level of desulfurization and further improving the efficiency of flue gas desulfurization.
