Technical Field
[0001] This utility model relates to the field of flue gas purification technology, specifically a multi-stage flue gas purification and waste heat recovery device. Background Technology
[0002] The flue gas generated during industrial production often carries a large amount of heat energy. If this heat energy is directly released into the atmosphere, it will cause a huge waste of energy.
[0003] Most existing multi-stage flue gas purification and waste heat recovery devices use filter plates for preliminary purification. However, due to prolonged use, a large amount of dust from the flue gas adheres to the filter plates, which may result in poor filtration efficiency. In addition, multi-stage flue gas purification and waste heat recovery devices utilize the heat exchange between overheated flue gas and water to achieve waste heat recovery. However, most devices use curved pipes for waste heat recovery, which causes localized overheating inside the water storage chamber, resulting in low waste heat recovery efficiency.

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.
[0018] Example: Figure 1-5 As shown, this utility model provides a multi-stage flue gas purification and waste heat recovery device, including a filter chamber 1, a purification chamber 2, and a water storage chamber 3. A flue gas inlet 20 is fixedly connected to the outer surface of the filter chamber 1, and the interior of the filter chamber 1 is fixedly connected to the interior of the purification chamber 2. A sliding cleaning assembly is installed inside the filter chamber 1, and a rotating heat dissipation assembly is installed on the outer surface of the water storage chamber 3. The sliding cleaning assembly includes a scraper 10. A filter plate 11 is slidably connected inside the filter chamber 1. An electric telescopic mechanism 4 is fixedly connected to the top of the filter chamber 1. One end of the output shaft of the electric telescopic mechanism 4 is fixedly connected to the outer surface of the scraper 10. A sliding groove 13 is opened inside the filter chamber 1. Multiple evenly distributed springs 12 are fixedly connected to the inner side of the sliding groove 13. A sliding plate 19 is fixedly connected to the end of each spring 12 away from the sliding groove 13. The outer surface of the sliding plate 19 is slidably connected to the interior of the sliding groove 13, and the top end of the sliding plate 19 is fixedly connected to the bottom end of the filter plate 11. By setting the filter chamber 1, the purification chamber 2, and the water storage chamber 3, a multi-stage flue gas purification and waste heat recovery device is provided. The multi-stage flue gas purification and waste heat recovery device consists of a purification chamber 2, a water storage chamber 3, an electric telescopic mechanism 4, a trigger alarm 5, a flue pipe 6, a recovery chamber 7, a motor 8, a water valve 17, and a flue outlet 20. A scraper 10 is installed so that the clogged filter plate 11 can be cleaned under the action of the electric telescopic mechanism 4 and the trigger alarm 5, preventing damage to the filter plate 11 due to prolonged use. A trigger alarm 5 is fixedly connected to the top of the filter chamber 1, with its switch located at the top inside the filter chamber 1, allowing it to detect and warn of filter plate 11 blockage. Multiple springs 12 are evenly distributed in a rectangular array on the inner side of the slide groove 13, allowing the filter plate 11 to reset after cleaning. A recovery chamber 7 is fixedly connected to the bottom of the filter chamber 1, with its opening corresponding to the outer surface of the scraper 10, allowing impurities cleaned by the scraper 10 to enter the recovery chamber 7.
[0019] The rotating heat dissipation assembly includes a flue pipe 6, the outer end of which is rotatably connected to the outer surface of the purification chamber 2. The outer surface of the flue pipe 6 is rotatably inserted into the outer surface of the water storage chamber 3. A placement plate 9 is fixedly connected to the outer surface of the water storage chamber 3, and a motor 8 is fixedly connected to the outer surface of the placement plate 9. A gear 14 is fixedly connected to one end of the output shaft of the motor 8. A ring rack 16 is fixedly connected to the outer surface of the flue pipe 6, and a diversion pipe 15 is fixedly connected to the outer surface of the flue pipe 6. By setting the flue pipe 6, the diversion pipe 15 and the motor... The machine 8 can stir the water inside the water storage chamber 3, so that the water inside the water storage chamber 3 is heated evenly. The water supply pipe 18 is fixedly connected to the outer surface of the water storage chamber 3, and the water valve 17 is fixedly connected to the outer surface of the water storage chamber 3, so that the water storage chamber 3 can be filled and drained. The inside of the flue pipe 6 is connected to the inside of the purification chamber 2, so that the purified flue gas can enter the inside of the flue pipe 6. The outer surface of the gear 14 meshes with the outer surface of the ring rack 16, so that the rotation of the gear 14 can drive the ring rack 16 to rotate.
[0020] Working principle: When the filter plate 11 becomes clogged due to prolonged flue gas filtration, the flue gas entering the filter chamber 1 through the flue gas inlet 20 will compress the filter plate 11. Under pressure, the filter plate 11 drives the sliding plate 19 to move inside the slide groove 13 and compress the spring 12. The spring 12 contracts under force, thereby moving the filter plate 11 toward the trigger alarm 5 and activating the trigger alarm 5. At the same time, the sliding plate 19 slides in the slide groove 13 to open the recovery chamber 7. The trigger alarm 5 is activated to sound an alarm. The operator can then start the electric telescopic machine 4. The output shaft of the electric telescopic machine 4 extends and retracts, driving the scraper 10 to scrape the filter plate 11 and push the impurities into the recovery chamber 7, thereby quickly cleaning the filter plate 11. Then, the flue gas passing through the filter plate 11 enters the purification chamber 2 for purification.
[0021] After purification, the flue gas inside the purification chamber 2 enters the flue pipe 6. The purified flue gas then enters the water storage chamber 3 along the flue pipe 6 and is then diverted into the diversion pipe 15. At the same time, the operator can start the motor 8. The output shaft of the motor 8 rotates, which drives the gear 14 to rotate. The rotation of the gear 14 drives the ring rack 16 to rotate, which in turn causes the flue pipe 6 to rotate. The rotation of the flue pipe 6 drives the diversion pipe 15 inside the water storage chamber 3 to rotate. Thus, the water inside the water storage chamber 3 is stirred by the rotation of the diversion pipe 15, so that the water inside the water storage chamber 3 is heated evenly, thereby improving the waste heat recovery efficiency.
[0022] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
