Description
Technical Field
[0001] This utility model relates to the technical field of carbon dioxide production equipment, specifically a desulfurization device for purifying carbon dioxide. Background Technology
[0002] In industrial production processes, many processes generate mixed gases containing carbon dioxide. These mixed gases often contain impurities such as sulfur dioxide. The presence of sulfur dioxide not only interferes with subsequent carbon dioxide purification but also causes equipment corrosion during use. Therefore, efficient desulfurization is a crucial step in carbon dioxide purification processes. The most common type of desulfurization device is the spray desulfurization unit, which removes sulfur through contact between the desulfurizing agent and the gas.
[0003] In traditional spray desulfurization devices, the contact time between gas and desulfurization liquid in the spray tower is relatively short. Due to the high gas flow rate in the tower, the contact with the liquid spray droplets is often only a brief moment. This prevents sulfur dioxide from fully reacting with the desulfurizing agent, resulting in poor desulfurization effect. Therefore, a desulfurization device that purifies carbon dioxide is needed to solve the above technical problems. Utility Model Content
[0004] The purpose of this invention is to provide a desulfurization device for purifying carbon dioxide, aiming to solve the problems in the prior art.
[0005] To achieve the above objectives, one embodiment of the present invention provides a desulfurization device for purifying carbon dioxide, comprising:
[0006] Spray tower;
[0007] Two guide rails are symmetrically installed on the inner wall of the spray tower. The length direction of the guide rails is parallel to the height direction of the spray tower. Multiple baffles are slidably connected to the outer surface of one guide rail and multiple baffles are slidably connected to the outer surface of the other guide rail. The baffles are spaced apart. Multiple fixing holes are provided on each guide rail. Each baffle and each baffle is provided with a baffle fixing assembly. The baffle fixing assembly is used to fix the baffles in a suitable position on the guide rail.
[0008] Multiple spraying components are installed on spoiler one and spoiler two. Each spraying component corresponds to one spoiler one and one spoiler two. The spraying components are used to spray desulfurizing agent.
[0009] Preferably, the spoiler fixing assembly includes a mounting groove, a guide rod, a fixing spring, a movable plate, and a fixing rod. Each of the spoilers, first and second, has a mounting groove. The guide rod and the fixing spring are connected to the inner wall of the mounting groove. The movable plate is slidably connected to the outer surface of the guide rod and is connected to the end of the fixing spring. The fixing rod is installed on the side of the movable plate away from the fixing spring and is inserted into the interior of the fixing hole.
[0010] Preferably, the spray assembly includes a connecting pipe, a branch pipe, a spray head, and a delivery hose. Each of the first and second baffles is connected to a connecting pipe. The branch pipe is connected to the connecting pipe. There are multiple spray heads, each of which is connected to a branch pipe. The delivery hose is connected to the end of the connecting pipe.
[0011] Preferably, a recycling bin is provided below the spray tower, and a partition and a filter screen are fixedly installed inside the recycling bin. The filter screen is inclined, and a conveying structure is provided on one side of the recycling bin.
[0012] Preferably, the conveying structure includes a conveying pump, a T-junction, and conveying branch pipes. The conveying pump is connected to the recovery box via a pipe. The T-junction is located inside the spray tower and is connected to the conveying pump via a pipe. There are two conveying branch pipes, each connected to a port of the T-junction. One conveying branch pipe is connected to the spray assembly connected to the uppermost baffle plate 1, and the other conveying branch pipe is connected to the spray assembly connected to the uppermost baffle plate 2.

[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. The gas flow path is enlarged by multiple spaced baffles (first and second), which prolongs the gas flow time. Each baffle (first and second) is equipped with a spray assembly.

[0027] The present invention will now be further described with reference to the accompanying drawings.
[0028] like Figures 1 to 8As shown, a desulfurization device for purifying carbon dioxide includes a spray tower 10. Two guide rails 11 are symmetrically installed on the inner wall of the spray tower 10. The length direction of the guide rails 11 is parallel to the height direction of the spray tower 10. Multiple baffles 20 are slidably connected to the outer surface of one guide rail 11, and multiple baffles 30 are slidably connected to the outer surface of the other guide rail 11. The baffles 20 and baffles 30 are spaced apart. Each baffle 20 and each baffle 30 is provided with a spray assembly for spraying desulfurizing agent. Multiple fixing holes 111 are opened on each guide rail 11. Each baffle 20 and each baffle 30 is provided with a baffle fixing assembly 40 for fixing the baffles 20 and baffles 30 at appropriate positions on the guide rail 11.
[0029] During the desulfurization and purification of carbon dioxide gas, multiple spaced-apart baffles 20 and 30 are used to move the gas between them, increasing the gas flow path and extending the flow time. Each baffle 20 and 30 is equipped with a spray assembly, which sprays the gas for desulfurization, resulting in a more effective desulfurization process.
[0030] It should be noted that the ends of both the first baffle plate 20 and the second baffle plate 30 are in contact with the inner wall of the spray tower 10, and the first baffle plate 20 and the second baffle plate 30 are slidably connected to the spray tower 10 to ensure the smooth movement of the first baffle plate 20 and the second baffle plate 30.
[0031] The spoiler fixing assembly 40 includes a mounting groove 41 formed on the first spoiler 20 and the second spoiler 30. A guide rod 42 and a fixing spring 43 are fixedly connected to the inner wall of the mounting groove 41. A movable plate 44 connected to the end of the fixing spring 43 is slidably connected to the outer surface of the guide rod 42. A fixing rod 45 is fixedly connected to the side of the movable plate 44 away from the fixing spring 43. The fixing rod 45 is inserted into the interior of the fixing hole 111. The movable plate 44 is slidably connected to the mounting groove 41.
[0032] When fixing spoiler 20 or spoiler 30, firstly, the moving plate 44 moves the fixing rod 45 and retracts it into the mounting groove 41. At this time, the fixing spring 43 is compressed. Then, the spoiler 20 or spoiler 30 is slidably connected to the guide rail 11, and the spoiler 20 or spoiler 30 is adjusted to a suitable position so that the fixing rod 45 corresponds to the position of the fixing hole 111. Then, the moving plate 44 can be slowly released. The reaction force of the fixed spring 43 causes the fixed insert rod 45 to be inserted into the fixed insert hole 111, thereby completing the installation of the first spoiler 20 or the second spoiler 30. This makes it easier to install, remove, and adjust the position of the first spoiler 20 or the second spoiler 30. Furthermore, an appropriate number of first spoilers 20 or second spoilers 30 can be selected and connected to the guide rail 11. The distance between two adjacent first spoilers 20 and two adjacent second spoilers 30 can be adjusted, thereby controlling the gas flow time.
[0033] The spray assembly includes a connecting pipe 50 connected to spoiler 1 20 and spoiler 2 30. Two branch pipes 51 are connected to the connecting pipe 50. Multiple spray heads 52 are installed on each branch pipe 51. A delivery hose 53 is connected to the end of the connecting pipe 50.
[0034] During the spraying operation, the desulfurizing agent is delivered to the inside of the two branch pipes 51 by the delivery hose 53 and the connecting pipe 50, and then sprayed out through multiple spray heads 52 to perform spraying desulfurization on the gas.
[0035] It should be noted that the spray components located on the multiple baffles 20 are interconnected through the delivery hose 53 and the connecting pipe 50, and the spray components located on the multiple baffles 30 are interconnected through the delivery hose 53 and the connecting pipe 50, so that the desulfurizing agent can enter the interior of the multiple spray components. The end of the connecting pipe 50 at the bottom is in a closed state, which prevents the liquid from being discharged directly from the connecting pipe 50 to the bottom of the spray tower 10.
[0036] A recycling bin 60 is installed below the spray tower 10. Inside the recycling bin 60, a partition 61 and a filter screen 62 are fixedly installed. The filter screen 62 is inclined and its bottom end is connected to the top side of the partition 61. The partition 61 and the filter screen 62 divide the inside of the recycling bin 60 into a filtration chamber and a clean water chamber. The bottom of the spray tower 10 is connected to the filtration chamber through a pipe. A conveying structure is provided on one side of the recycling bin 60.
[0037] After spraying, the desulfurizing agent is transported through pipelines to the interior of the filter chamber. The desulfurizing agent is filtered through filter screen 62, thereby removing impurities in the desulfurizing agent. The filtered desulfurizing agent enters the interior of the clean water chamber and is then transported through a conveying structure to the interior of the spray tower 10 for spraying, thus realizing the recycling of the desulfurizing agent.
[0038] The conveying structure includes a conveying pump 63. The inlet of the conveying pump 63 is connected to the clean water chamber through a pipe. The outlet of the conveying pump 63 is connected to a tee pipe 64 through a pipe. The other two connection ports of the tee pipe 64 are fixedly connected to conveying branch pipes 65. One conveying branch pipe 65 is connected to the spray assembly connected to the uppermost baffle plate 20, and the other conveying branch pipe 65 is connected to the spray assembly connected to the uppermost baffle plate 30.
[0039] Start the delivery pump 63, and the desulfurizing agent is delivered through the pipeline and the tee pipe 64 to the inside of the two delivery branch pipes 65. The desulfurizing agent is then delivered to the inside of the spray assembly through the delivery branch pipes 65, thereby spraying out the desulfurizing agent for desulfurization operation.
[0040] Both spoiler 1 20 and spoiler 2 30 are connected to two limiting sliders 70. Each guide rail 11 has two limiting grooves 112 on one side. The limiting sliders 70 are located inside the limiting grooves 112 and are slidably connected to the limiting grooves 112. The limiting sliders 70 and the limiting grooves 112 correspond one-to-one.
[0041] When connecting spoiler 20 to guide rail 11 or spoiler 30 to guide rail 11, the limiting slider 70 enters the interior of the limiting groove 112, and the limiting slider 70 moves with the movement of spoiler 20 and spoiler 30. The limiting slider 70 and the limiting groove 112 can prevent spoiler 20 and spoiler 30 from separating from guide rail 11 during movement.
[0042] Each spoiler 20 and spoiler 30 has a sealing groove 80 on one side. The sealing groove 80 is connected to the mounting groove 41, and the size of the sealing groove 80 is larger than the size of the mounting groove 41. Each sealing groove 80 has a sealing cover plate 81 inside it. The sealing cover plate 81 is provided with a snap-fit groove, which makes it easy to remove the sealing cover plate 81 from the inside of the sealing groove 80.
[0043] The sealing cover plate 81 and the sealing groove 80 can cover and seal the mounting groove 41, thereby better preventing the desulfurizer from entering the mounting groove 41 and thus avoiding the impact of the desulfurizer on the fixed spring 43, ensuring the service life of the fixed spring 43.
