Description

Technical Field

[0001] This utility model relates to the field of flue gas purification technology, specifically a deep purification device for flue gas from coal-based kaolin. Background Technology

[0002] Flue gas purification is a technical system for treating pollutant-containing flue gas generated during industrial production and energy utilization. Its core objective is to remove harmful substances such as particulate matter, sulfur dioxide, nitrogen oxides, heavy metals, and dioxins from flue gas through physical, chemical, or biological methods, thereby reducing pollution to the atmospheric environment and harm to human health. However, the inability to reduce the energy consumption of the equipment during use leads to a significant increase in operating costs and accelerates wear and tear, reducing the service life of the equipment.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application number 201920904053.4, application date 2019-06-14) provides a water-saving and energy-saving flue gas purification device, including a scrubbing tower, a scrubbing pump, a condensate pump, a condensate clarification tank, and an air-cooled grid; it recovers heat from the scrubbing slurry and high-temperature flue gas through indirect condensation, reducing the amount of water evaporation during the scrubbing process; it recovers heat and gaseous moisture in the flue gas through direct spray condensation, and uses the recovered heat to increase the inlet air temperature of the coal-fired boiler furnace; this water-saving and energy-saving flue gas purification device can fully utilize the waste heat of the flue gas while significantly reducing the water consumption of the flue gas purification device, and can also reduce the coal consumption per unit power generation of the generator set.

[0004] The flue gas produced during the production of coal-based kaolin typically contains a large amount of dust. These dust particles vary in size, and large dust particles may accumulate on the surface of the filter plate, while small dust particles easily enter the pores of the filter plate. Over time, these particles gradually accumulate and cause blockage. During the use of the aforementioned device, filter plate blockage cannot be avoided, resulting in a significant decrease in filtration capacity. A large amount of dust, particulate matter, and some gaseous pollutants that have not been fully adsorbed cannot be effectively intercepted, which will exacerbate environmental pollution and affect the surrounding ecological environment and residents' health.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the deep purification device for coal-series kaolin flue gas adopts a novel structural design, the specific details of which are as follows:

[0014] This coal-series kaolin flue gas deep purification device, through the setting of filter plates and buffer springs, can effectively shake off the particles accumulated on the surface of the filter plates, prevent them from clogging the filter holes, maintain the air permeability of the filter plates, ensure that the filtration process is continuously and efficiently carried out, make the flue gas more evenly distributed on the entire filter surface, improve the overall filtration effect, and ensure the consistency of the quality of the purified flue gas.

[0016] This coal-series kaolin flue gas deep purification device, through the setting of activated carbon plates and support frames, enables pollutants in the flue gas to diffuse more quickly to the surface of the activated carbon plates and be adsorbed, accelerating the transfer of pollutants from the main body of flue gas to the surface of the activated carbon plates, increasing the adsorption reaction rate, and enabling the activated carbon plates to adsorb more pollutants in a shorter time.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: The purification box 1, limit rod 8, and sliding rod 14 improve the stability of the device during operation and prevent shaking. Figures 1-2 As shown: It includes a purification box 1, a fan 3 is fixedly connected to the upper surface of the purification box 1, a control console 2 is fixedly connected to the lower front end of the purification box 1, and a water tank 22 is fixedly connected to the upper rear end of the purification box 1. At the same time, a spray assembly 23 is fixedly connected to the inner wall of the purification box 1 near the fan 3. A fixing plate 7 is fixedly connected to the inner wall of the purification box 1, and a limit rod 8 is fixedly connected to the lower end of the fixing plate 7. The limit rod 8 is slidably connected to a filter plate 9, and the filter plate 9 is slidably disposed inside the purification box 1. A fixing block 13 is fixedly connected to the inner wall of the purification box 1 near the spray assembly 23, and a sliding rod 14 is fixedly connected to the surface of the fixing block 13. The sliding rod 14 is slidably connected to an activated carbon plate 15, and the activated carbon plate 15 is slidably disposed inside the purification box 1.

[0029] The staff placed the purification box 1 in the designated position, ensuring that the suction port of the purification box 1 was aligned with the source of the smoke. The staff then activated the fan 3 via the control panel 2. The fan 3 generated suction, drawing the pollutant-laden flue gas produced during the coal-based kaolin production process into the purification box 1. Figure 1 As shown, when the polluted flue gas flows through the purification box 1 to the activated carbon plate 15, it can adsorb the harmful gases in the flue gas, further reducing the pollutant content in the flue gas. Figure 2As shown, the adsorbed flue gas flows to the filter plate 9 inside the purification chamber 1. The filter plate 9 performs secondary interception of residual particulate pollutants in the flue gas, further removing dust and other solid impurities and improving the cleanliness of the flue gas. At the same time, the water source inside the water tank 22 flows into the purification chamber 1 from the nozzles on the surface of the spray assembly 23. Figure 2 As shown, this achieves deep purification of flue gas, which not only improves the purification efficiency of the device and can more effectively reduce the pollutant content in the flue gas, but also makes the purified flue gas cleaner.

[0030] Example 2: In this example, unlike Example 1, the rotating shaft 5, buffer spring 12, and connecting rod 6 are used to prevent the filtration effect from being affected by a large amount of dust accumulating instantaneously, thus enhancing the device's adaptability to flue gas fluctuations. Figures 3-4 As shown: A motor 4 is fixedly connected to the upper right side of the purification box 1, and a rotating shaft 5 is fixedly connected to the output end of the motor 4. The rotating shaft 5 is rotatably located inside the purification box 1. A connecting rod 6 is fixedly connected to the surface of the rotating shaft 5. The connecting rod 6 is rotatably located inside the purification box 1, and the end of the connecting rod 6 is arc-shaped. A connecting column 10 is fixedly connected to the surface of the filter plate 9, and a connecting plate 11 is fixedly connected to the end of the connecting column 10. One end of a buffer spring 12 is fixedly connected to the lower surface of the connecting plate 11, and the other end of the buffer spring 12 is fixedly connected to the purification box 1.

[0031] When the motor 4 is working, it drives the output shaft 5 to rotate inside the purification chamber 1, and also drives the connecting rod 6 on the surface of the shaft 5 to rotate inside the purification chamber 1. Figure 3 As shown, when the connecting rod 6 contacts the connecting column 10, the connecting rod 6 pushes the connecting column 10 to slide on the surface of the limiting rod 8, causing the filter plate 9 on the surface of the connecting column 10 to rotate inside the purification box 1. At the same time, the buffer spring 12 at the lower end of the connecting plate 11 retracts towards the purification box 1. Figure 4 As shown, this allows the filter plate 9 to slide inside the purification chamber 1, effectively shaking off the particles accumulated on the surface of the filter plate 9, preventing them from clogging the filter holes, maintaining the air permeability of the filter plate 9, ensuring that the filtration process continues to be efficient, making the flue gas more evenly distributed on the entire filter surface, improving the overall filtration effect, and ensuring the consistency of the quality of the purified flue gas.

[0032] In Example 3, unlike Example 2, the activated carbon plate 15, support frame 18, and protrusions 16 ensure that the pores of the activated carbon remain open, guaranteeing that the activated carbon plate 15 maintains high adsorption activity. Figures 5-7As shown: A connecting block 21 is fixedly connected to the inner wall of the purification box 1, and a sliding plate 20 is slidably connected inside the connecting block 21. A support frame 18 is fixedly connected to the surface of the sliding plate 20. The support frame 18 is slidably disposed inside the purification box 1. A first gear 17 is fixedly connected to one end of the rotating shaft 5 near the connecting block 21. The first gear 17 is half-gear shaped. A toothed block 19 is fixedly connected to the inner wall of the support frame 18. The toothed blocks 19 are evenly distributed on the inner wall of the support frame 18. The toothed blocks 19 are meshed with the first gear 17. The first gear 17 is rotatably disposed inside the purification box 1. A protrusion 16 is fixedly connected to one end of the surface of the water tank 22 near the activated carbon plate 15. The surface of the protrusion 16 is arc-shaped. The activated carbon plate 15 is fixedly connected to the surface of the sliding plate 20.

[0033] As the rotating shaft 5 rotates inside the purification chamber 1, it drives the first gear 17 on the surface to rotate inside the purification chamber 1, causing the first gear 17 to mesh with the toothed block 19 on the inner wall of the support frame 18. Figure 5 As shown, when the rotating shaft 5 rotates, it causes the sliding plate 20 on the surface of the support frame 18 to slide inside the connecting block 21, and the surface of the sliding plate 20 is connected to the activated carbon plate 15, so that the activated carbon plate 15 slides on the surface of the sliding rod 14 as shown. Figure 6 As shown, this allows pollutants in the flue gas to diffuse more quickly to the surface of the activated carbon plate 15 and be adsorbed, accelerating the transfer of pollutants from the main body of the flue gas to the surface of the activated carbon plate 15, increasing the adsorption reaction rate, and enabling the activated carbon plate 15 to adsorb more pollutants in a shorter time. When the activated carbon plate 15 comes into contact with the protrusions 16 on the surface of the water tank 22, the activated carbon plate 15 squeezes the protrusions 16 against the water tank 22. Figure 7 As shown, the internal space of the water tank 22 is compressed, so that the water in the water tank 22 flows out from the nozzle of the spray assembly 23 to form a spraying effect, which can change the physicochemical properties of the adsorbent surface and enhance the adsorbent's ability to adsorb gaseous pollutants.

[0034] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
