[0002] Waste gas refers to the gas discharged into the atmosphere during industrial or living processes, which may contain various harmful substances, such as sulfur dioxide, nitrogen oxides, particulate matter, etc. These substances will have a serious impact on the environment and human health, so effective treatment and control are required. Desulfurization is a common waste gas treatment method, mainly used to remove sulfur dioxide in waste gas. Sulfur dioxide is a gas with a strong pungent smell, which will not only cause harm to human health, but also lead to environmental problems such as acid rain. Through desulfurization technology, sulfur dioxide in waste gas can be converted into harmless substances, thereby reducing environmental pollution.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0033] Refer to Figure 1 - Figure 3 As an embodiment provided by the present utility model: An exhaust gas desulfurization and purification device includes a purification tower 1. The purification tower 1 is the core part of the entire device and is used to accommodate and process exhaust gas. A conical ring 2 is fixedly connected to the top of the purification tower 1. A first limiting ring 3 is rotatably connected to the top of the conical ring 2. The first limiting ring 3 not only plays a fixing role but also allows the fixing frame 4 to rotate within the conical ring 2. A fixing frame 4 is fixedly connected to the inside of the first limiting ring 3. The outside of the fixing frame 4 is rotatably connected to the inside of the conical ring 2. The design of the fixing frame 4 enables the lime water to be evenly distributed. A water inlet pipe 5 is rotatably connected to the top of the fixing frame 4. The water inlet pipe 5 is responsible for transporting lime water into the purification tower 1. A second limiting ring 6 is fixedly connected to the bottom side of the outside of the water inlet pipe 5. The outside of the second limiting ring 6 is rotatably connected to the inside of the fixing frame 4. A fixing column 7 is fixedly connected to the inside of the fixing frame 4. A connecting frame 8 is fixedly connected to the outside of the fixing column 7. A conical block 9 is fixedly connected to the top of the fixing column 7. The conical block 9 is designed to guide the lime water to impact around, improving the atomization efficiency. A fan blade 10 is fixedly connected to the outside of the fixing column 7. A plurality of atomizing nozzles 11 are fixedly connected to the bottom side of the outside of the fixing frame 4. The atomizing nozzles 11 are responsible for atomizing the lime water and spraying it evenly, increasing the contact area with the exhaust gas and improving the desulfurization efficiency. When the lime water impacts, the fan blade 10 rotates, driving the fixing frame 4 to rotate, realizing the circular motion of the atomizing nozzles 11. An air inlet pipe 12 is fixedly connected to the right side of the outside of the purification tower 1. A filter frame 14 is arranged inside the air inlet pipe 12 for introducing the exhaust gas to be purified. An air outlet pipe 13 is fixedly connected to the left side of the outside of the purification tower 1. A replacement component for quick disassembly is arranged inside the air inlet pipe 12.

[0034] Refer to Figure 3 - Figure 5, the replacement component includes a filter box 14. The outside of the filter box 14 is slidably connected inside the intake pipe 12. A carbon plate 15 is fixedly connected to the left side of the filter box 14. The filter box 14 and the carbon plate 15 are used to initially filter large particulate impurities in the waste gas. The outside of the carbon plate 15 is slidably connected inside the intake pipe 12. A connecting block 16 is fixedly connected to the top of the filter box 14. A connecting frame 17 is fixedly connected to the top side of the outside of the intake pipe 12. The outside of the filter box 14 is slidably connected inside the connecting frame 17. A pull rod 18 is fixedly connected to the top of the connecting block 16. The pull rod 18 is used by the operator to lift or press down the filter box 14 and the carbon plate 15. Slide grooves 19 are formed in the front and rear sides inside the connecting block 16. Circular grooves 20 are formed in the front and rear sides inside the connecting block 16. When the filter box 14 needs to be disassembled, the limiting plate 22 can slide in the slide groove 19 and rotate in the circular groove 20 to help lock and unlock the filter box 14, thereby allowing the filter box 14 and the carbon plate 15 to be pulled out. Two sliding rods 21 are slidably connected inside the connecting block 16. Limiting plates 22 are fixedly connected to the adjacent sides of the two sliding rods 21. The outside of the limiting plate 22 is slidably connected inside the connecting block 16, slidably connected inside the slide groove 19, and rotatably connected inside the circular groove 20. Springs 23 are sleeved on the outside of the two sliding rods 21. The inward and outward movement of the sliding rods is controlled by the springs 23 to realize the fixing and disassembly of the filter box 14. The function of the spring 23 is to provide the necessary pressure for the filter box 14 to maintain its stability in the working state and provide a restoring force during disassembly;

[0035] Refer to Figure 4 - Figure 6, on the outside of both sliding rods 21, there is a first fixed ring 24 in sliding connection. On the outside of both first fixed rings 24, there is a first rotating ring 25 in rotational connection. The first rotating ring 25 plays a role in transmitting tensile force and compressing the spring 23 during the disassembly process of the filter frame 14. The first fixed ring 24 serves as the support structure for the first rotating ring 25. The side of the first fixed ring 24 away from the first rotating ring 25 is fixedly connected to the outside of the connection frame 17. On the outside of both sliding rods 21, there is a second rotating ring 26 in rotational connection. The second rotating ring 26 cooperates with the first rotating ring 25 to jointly control the compression and extension of the spring 23, thereby controlling the fixation and disassembly of the filter frame 14. On the adjacent sides of both second rotating rings 26, there is a second fixed ring 27 in rotational connection. The second fixed ring 27 serves as the support structure for the second rotating ring 26. One end of the spring 23 is fixedly connected to the side of the first rotating ring 25 away from the first fixed ring 24, and the other end of the spring 23 is fixedly connected to the side of the second rotating ring 26 away from the second fixed ring 27. On the opposite sides of both sliding rods 21, there is a pull plate 28 fixedly connected. On the bottom side inside the purification tower 1, there is a collection box 29 in sliding connection. The collection box 29 is used to collect the solid waste generated during the purification process, which is convenient for cleaning and maintenance. On the front side of the collection box 29, there is a fixed semi-ring 30 fixedly connected. On the front side of the fixed semi-ring 30, there is a handle 31 fixedly connected.

[0036] Working principle: First, inject lime water into the inside of the purification tower 1 through the water inlet pipe 5. At the same time, it is necessary to inject the waste gas to be purified into the inside of the air inlet pipe 12. At this time, the lime water can enter the inside of the fixed frame 4. Subsequently, the lime water impacts the outside of the conical block 9 and impacts in all directions. Then it can impact the outside of the fan blades 10. At this time, the fan blades 10 will rotate. At this time, it can drive the fixed frame 4 to rotate, and then the atomizing nozzle 11 can make a circular motion. At this time, the lime water can be atomized and sprayed out through the atomizing nozzle 11. Then the lime water can be sprayed out evenly over a larger area. At this time, the waste gas can be fully contacted with the lime water, and then the desulfurization efficiency can be greatly improved. When it is necessary to disassemble the filter frame 14 and the activated carbon plate 15, first rotate the pull plate 28 at this time. Then the pull plate 28 will drive the 21, the second fixed ring 27 and the first fixed ring 24 to rotate. Then the limiting plate 22 will rotate. At this time, the limiting plate 22 will be aligned with the sliding groove 19. Then pull the pull plate 28 outward. At this time, the limiting plate 22 can slide out of the sliding groove 19, and the first rotating ring 25 will be displaced, and then the spring 23 will be compressed. At this time, the sliding rod 21 and the limiting plate 22 will both be disengaged from the inside of the connection block 16. At this time, pull the pull rod 18 upward, and then the filter frame 14 and the activated carbon plate 15 can be taken out. At this time, the disassembly is completed.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
