Description

Technical Field

[0001] This invention relates to the field of liquid sulfur dioxide dehydration technology, specifically to a dehydration device for processing liquid sulfur dioxide. Background Technology

[0002] Sulfur dioxide, the most common and simplest sulfur oxide with the chemical formula SO2, is a colorless, transparent gas with a pungent odor. It is soluble in water, ethanol, and ether. Sulfur dioxide is one of the major air pollutants. It is emitted during volcanic eruptions and produced in many industrial processes. Since coal and petroleum typically contain sulfur, they generate sulfur dioxide upon combustion. When sulfur dioxide dissolves in water, it forms sulfurous acid. Further oxidation of sulfurous acid in the presence of PM2.5 rapidly and efficiently produces sulfuric acid.

[0003] Currently, when removing water from liquid sulfur dioxide, it is first irradiated with ultraviolet lamps or heated at high temperatures to convert the liquid sulfur dioxide into gas and water vapor. Then, a high-concentration drying acid is sprayed from the top of the drying tower, allowing the drying acid to fully contact the sulfur dioxide gas. After contact, the drying acid absorbs the water vapor from the sulfur dioxide gas, resulting in dried sulfur dioxide gas. This gas is then compressed using a compressor to liquefy it, and then stored.

[0004] Because the water vapor was not pre-treated during the drying of sulfur dioxide gas, a large amount of drying acid was required. However, the drying acid became saturated after absorbing the water vapor in the sulfur dioxide gas, and could no longer absorb sulfur dioxide water vapor. Therefore, the drying acid needed to be replaced frequently, resulting in a waste of resources and a reduction in the drying effect. Summary of the Invention

[0016] This invention provides a dehydration device for processing liquid sulfur dioxide. Compared with the prior art, it has the following advantages:

[0017] Beneficial effects:

[0018] 1. By starting the heating equipment and drive motor, the hot air heated by the heating equipment enters the hollow column and insulation layer through the heating pipe and hot air pipe respectively. The hot air entering the hollow column will then enter the stirring pipe and be dissipated through the heat sink to start heating the sulfur dioxide aqueous solution in the dewatering tank. At this time, internal and external heating can be achieved. When the drive motor works, it will drive the hollow pipe, stirring pipe and hollow cylinder to rotate, so that the sulfur dioxide aqueous solution can be heated evenly during heating.

[0019] 2. The rotation of the hollow cylinder drives the rotation of the drive shaft. The rotation of the drive shaft drives the rotation of the drive gear, which in turn drives the rotation of the self-rotating gear. The rotation of the self-rotating gear drives the self-rotating rod, the first drive disc, the main body, the cooling pipe, and the collecting plate to rotate. When the collecting plate rotates, it begins to adsorb water vapor on its surface, while sulfur dioxide gas passes through the air inlet. At this time, the external cooling equipment delivers cold air through the air supply ring and rectangular channel into the hollow cross, then through the hollow cross into the cooling pipe, and finally through the cooling pipe to the mist collecting plate, cooling the hot water vapor on the surface of the mist collecting plate into water droplets, thus separating the sulfur dioxide gas from the water vapor.

[0020] 3. When the drive shaft rotates, it will also drive the rotating disk to rotate. When the rotating disk rotates, sulfur dioxide gas will be discharged upward through the exhaust port, while water vapor will be blocked by the rotating disk. When the rotating disk rotates, the water vapor adsorbed at its bottom will also be scraped off by the scraper.

[0021] 4. When sulfur dioxide gas flows upward from the vent, it enters the gas flow cylinder 65 and is then discharged from the drying hole on the gas flow cylinder. The discharged sulfur dioxide gas will come into contact with the dry sulfuric acid flowing on the inner wall of the liquid flow cylinder. After contact, the water vapor in the sulfur dioxide gas can be dried.

[0022] 5. Sulfur dioxide gas flows upward through the vent hole, and then flows upward in the middle of the isolation ring. At this time, the sulfur dioxide gas will come into contact with the top surface of the cap. After contact, the sulfur dioxide gas will flow out from the gap between the isolation ring and the cap. The outflowing sulfur dioxide gas will come into contact with the dry sulfuric acid on the isolation plate, and the dry sulfuric acid will remove the moisture.

[0023] 6. Using a liquid pump in conjunction with the liquid outlet and liquid inlet pipes, the dry sulfuric acid on the isolation plate is drawn into the spray ring. Then, the dry sulfuric acid is sprayed onto the surface of the vent hood through the nozzle. When the sulfur dioxide gas enters from the air inlet on the vent hood, it will come into full contact with the dry sulfuric acid to remove moisture. After the moisture enters, it will reach the compressor. At this time, the compressor will start to compress the sulfur dioxide gas. The compressed sulfur dioxide gas is liquid and is stored in a storage tank. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, 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.

[0037] Example 1

[0038] To address the technical problems in the background section, the following dehydration device for processing liquid sulfur dioxide is provided:

[0039] Combination Figures 1-10As shown, the dehydration device for processing liquid sulfur dioxide provided by the present invention includes a mounting plate 1; a dehydration tank 2 is fixedly connected to the top surface of the mounting plate 1; a heating component 3 is installed in the lower part of the inner cavity of the dehydration tank 2; a demisting component 4 is installed in the inner cavity of the dehydration tank 2 and above the heating component 3; an isolation component 5 is installed in the inner cavity of the dehydration tank 2 and above the demisting component 4; a dehydration component 6 is installed in the inner cavity of the dehydration tank 2 and above the isolation component 5; an exhaust compression component 7 is connected to the top surface of the inner cavity of the dehydration tank 2; a spraying component 8 is installed on the top surface of the inner cavity of the dehydration tank 2 and on the outer surface of the exhaust compression component 7; a heat insulation layer 9 is fixedly connected to the lower part of the outer surface of the dehydration tank 2; the air inlet end of the heat insulation layer 9 communicates with the inner cavity of the heating device 11 through a heating pipe 10; and an exhaust fan is fixedly connected to the bottom surface of the dehydration tank 2. Water pipe 12, drain pipe 12 has valves installed inside its cavity, and flange 13 is fixedly connected to the lower part of the outer surface of water tank 2; heating component 3 includes drive motor 31, drive motor 31 is fixedly connected to the bottom surface of water tank 2, the output shaft end of drive motor 31 is rotatably connected to hollow tube 32 through worm gear and worm wheel, one end of hollow tube 32 passes through water tank 2 and is rotatably connected to water tank 2, the inlet and outlet ends of hollow tube 32 are connected to the inner cavity of heating equipment 11 through hot air pipe 33, hollow cylinder 34 is fixedly connected to the top surface of hollow tube 32 and is connected to the inner cavity of hollow tube 32, stirring tube 35 is fixedly connected at equal intervals to the outer surface of hollow cylinder 34 and is connected to the inner cavity of hollow cylinder 34, heat sink 36 is symmetrically fixedly connected to the outer surface of stirring tube 35.

[0040] By starting the heating device 11 and the drive motor 31, the hot air heated by the heating device 11 enters the hollow column 34 and the insulation layer 9 through the heating pipe 10 and the hot air pipe 33, respectively. The hot air entering the hollow column 34 will then enter the stirring pipe 35 and be dissipated through the heat sink 36, thus starting to heat the sulfur dioxide aqueous solution in the dewatering tank 2. At this time, internal and external heating can be achieved. When the drive motor 31 is working, it will drive the hollow pipe 32, the stirring pipe 35 and the hollow column 34 to rotate, so that the sulfur dioxide aqueous solution can be uniformly heated during heating.

[0041] In order to enable the demister assembly 4 to remove the gas-liquid mixture generated during heating of sulfur dioxide liquid and to achieve better separation of gas and liquid gas, this embodiment provides the following technical solution:

[0042] In this embodiment, the defogging assembly 4 includes a hollow cross 41 and a drive shaft 42. The hollow cross 41 is fixedly connected to the upper part of the inner cavity of the water tank 2. The drive shaft 42 is fixedly connected to the top surface of the hollow cylinder 34. The top surface of the drive shaft 42 passes through the middle of the hollow cross 41 and is rotatably connected to the hollow cross 41. A cooling component 45 is rotatably connected to the outer surface of the drive shaft 42 through a transmission gear 44. A blocking component 46 is installed on the top surface of the drive shaft 42. The cooling component 45 includes a first transmission disk 451, which is rotatably connected to the inner cavity of the hollow cross 41. A rotating rod 453 is fixedly connected to the top surface of the first transmission disk 451. One end of the rotating rod 453 passes through the hollow cross 41 and is fixedly connected to a rotating gear 454. The rotating gear 454 meshes with a transmission gear 44. A column 455 is rotatably connected to the bottom surface of the first transmission disk 451 at equal intervals. A cooling pipe 456 is fixedly connected to the bottom surface of the column 455. The bottom surface of the cooling pipe 456 passes through the hollow cross 41 and is fixedly connected to a mist collecting plate 457. Air vents 458 are provided at equal intervals on one side of the mist collecting plate 457. The inner cavity of the mist collecting plate 457 communicates with the inner cavity of the hollow cross 41 through the cooling pipe 456. The cooling component 45 also includes an air supply ring 452. The air supply ring 452 is installed on the outer surface of the water tank 2. The inner surface of the air supply ring 452 communicates with the inner cavity of the hollow cross 41 through a rectangular channel 459. The air inlet end of the air supply ring 452 communicates with the inner cavity of the cooling device 4511 through a cold air delivery pipe 4510. The blocking component 46 includes a sealing ring 461. The sealing ring 461 is fixedly connected to the inner wall of the water tank 2 and above the hollow cross 41. Scrapers 462 are symmetrically fixedly connected to the inner wall of the sealing ring 461. A rotating disk 463 is fixedly connected to the top surface of the drive shaft 42. Exhaust holes 464 are arranged in a circumferential array on the top surface of the rotating disk 463. The top surface of the scraper 462 contacts the bottom surface of the rotating disk 463, and the bottom surface of the rotating disk 463 contacts the top surface of the sealing ring 461.

[0043] The rotation of the hollow cylinder 34 drives the rotation of the transmission shaft 42. The rotation of the transmission shaft 42 drives the transmission gear 44 to rotate, which in turn drives the rotation of the self-rotating gear 454. The rotation of the self-rotating gear 454 drives the self-rotating rod 455, the first transmission disc 451, the main body 455, the cooling pipe 456, and the collecting plate 457 to rotate. When the collecting plate 457 rotates, it begins to adsorb water vapor on its surface, while sulfur dioxide gas passes through the air vent 458. At this time, the external cooling device 4511 delivers cold air through the air supply ring 452 and the rectangular channel 459 into the hollow cross 41. Then, it is delivered through the hollow cross 41 into the cooling pipe 456. Finally, it is delivered through the cooling pipe 456 to the mist collecting plate 457, cooling the hot water vapor on the surface of the mist collecting plate 457 into water droplets, thus separating the sulfur dioxide gas from the water vapor.

[0044] When the drive shaft 42 rotates, it will also drive the rotating disk 463 to rotate. When the rotating disk 463 rotates, sulfur dioxide gas will be discharged upward through the exhaust port 464, while water vapor will be blocked by the rotating disk 463. When the rotating disk 463 rotates, the water vapor adsorbed at its bottom will also be scraped off by the scraper 462.

[0049] Sulfur dioxide gas flows upward through the vent 52, and then flows upward in the middle of the isolation ring 53. At this time, the sulfur dioxide gas will come into contact with the top surface of the cap 56. After contact, the sulfur dioxide gas will flow out from the gap between the isolation ring 53 and the cap 56. The outflowing sulfur dioxide gas will come into contact with the dry sulfuric acid on the isolation plate 51 and the dry sulfuric acid will remove the water vapor.

[0050] When sulfur dioxide gas flows upward from the vent 64, it enters the gas outlet 65 and is then discharged from the drying hole 67 on the gas outlet 65. The discharged sulfur dioxide gas will come into contact with the dry sulfuric acid flowing on the inner wall of the liquid outlet 63. After contact, the water vapor in the sulfur dioxide gas can be dried, and the dry sulfuric acid will be discharged from the liquid outlet 67.

[0055] The dry sulfuric acid on the isolation plate 51 is drawn into the spray ring 81 by the pump 82 in conjunction with the outlet pipe 84 and the inlet pipe 83. Then, the dry sulfuric acid is sprayed onto the surface of the vent 71 through the nozzle 85. When the sulfur dioxide gas enters from the air inlet 73 on the vent 71, it will come into full contact with the dry sulfuric acid to remove moisture. After the moisture enters, it will reach the compressor 72. At this time, the compressor 72 will start to compress the sulfur dioxide gas.
