[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution:

[0022] Example 1

[0023] Regarding the aforementioned problems: some existing waste-to-energy flue gas treatment devices filter impurities in the flue gas using water in a water tank. However, these impurities accumulate at the bottom of the water tank and adhere to its inner walls, making it difficult for staff to clean the bottom and inner walls of the tank and hindering maintenance.

[0024] The solution is as follows: A flue gas treatment device for waste-to-energy generation includes a device body 1. The device body 1 includes a main flue gas treatment box 2, an auxiliary flue gas treatment device 3, a flue gas input pump 4, an impurity conveying pump 5, and an impurity removal device 6. The auxiliary flue gas treatment device 3 is located behind the main flue gas treatment box 2. The flue gas input pump 4 is located at the left end of the main flue gas treatment box 2. The impurity conveying pump 5 is located at the right side of the main flue gas treatment box 2. The impurity removal device 6 is installed inside the main flue gas treatment box 2. The main flue gas treatment box 2 has a cylindrical structure and a hollow interior. A filter block 7 is provided inside the main flue gas treatment box 2. The filter block 7 has a cylindrical structure and a filter groove 8 is formed at the top of the filter block 7. The filter groove 8 has a funnel-shaped structure and is filled with filtered water 9. The impurity removal device 6... The device 6 includes a heat-insulating mounting plate 24, a motor 25, a rotating rod 26, a horizontal block 27, a scraper mounting block 28, and a cleaning scraper 29. The heat-insulating mounting plate 24 is welded inside the main flue gas treatment box 2. The motor 25 is mounted on the top of the heat-insulating mounting plate 24. The rotating rod 26 is mounted on the drive end of the motor 25 and located below the heat-insulating mounting plate 24. A set of horizontal blocks 27 is provided, and a set of horizontal blocks 27 are respectively welded to the bottom side of the rotating rod 26. The scraper mounting block 28 is welded to the outer end of the horizontal block 27 in an inclined manner. The outer end of the scraper mounting block 28 has a mounting groove 30. The cleaning scraper 29 is fixed in the mounting groove 30 by screws. Both the cleaning scraper 29 and the scraper mounting block 28 have several sets of locking holes 31 on their surfaces. The outer end of the cleaning scraper 29 is located on the inner wall of the filter tank 8.

[0025] Analysis of the above: The flue gas input pump 4 delivers the waste-to-energy flue gas to the flue gas input pipe 12 inside the main flue gas treatment box 2. The bottom of the flue gas input pipe 12 extends into the filtered water 9 in the filter tank 8, allowing the flue gas to fully contact the filtered water and achieve preliminary impurity filtration. Simultaneously, the motor 25 of the impurity removal device 6 starts, driving the rotating rod 26, the horizontal block 27, and the scraper mounting block 28 to rotate, causing the cleaning scraper 29 to rotate along the inner wall of the funnel-shaped filter tank 8 and scrape off the attached impurities. The heat insulation mounting plate 24 isolates the flue gas treatment area from the heat transfer between the motor 25 and the filter tank 8. When impurities are attached to the inner wall of the filter tank 8, the motor 25 is started for cleaning. When the filtered water 9 is insufficient, filtered water is added through the water inlet pipe 13. The funnel-shaped filter tank 8 facilitates the collection of impurities to the bottom, and the cleaning scraper 29 can efficiently remove impurities attached to the inner wall, preventing impurity accumulation from affecting filtration. The heat insulation mounting plate 24 ensures that the motor 25 operates stably at a suitable temperature. The water inlet pipe 13 can replenish water in a timely manner to maintain the continuous filtration capacity of the main box.

[0026] Example 2:

[0027] Please see Figure 1-4 The present invention provides a technical solution based on Embodiment 1: an impurity discharge pipe 10 is installed at the bottom of the filter block 7, the impurity discharge pipe 10 and the filter tank 8 are in a through structure, the output end of the impurity discharge pipe 10 is connected to the input end of the impurity conveying pump 5, and a valve 11 is installed inside the impurity discharge pipe 10.

[0028] Analysis of the above content: After filtration, the impurities deposited at the bottom of the filter tank 8 are extracted by the impurity delivery pump 5 through the impurity discharge pipe 10, which is connected to the filter tank 8, and transported to an external collection device when the valve 11 is opened; periodically or when the impurities at the bottom of the filter tank 8 accumulate to a certain extent, the valve 11 is opened and the impurity delivery pump 5 is started to discharge the impurities; the impurity discharge pipe 10 and the impurity delivery pump 5 work together to discharge the bottom deposited impurities in a timely manner, prevent the filter tank from clogging, and greatly reduce the difficulty and workload of manual cleaning; the valve 11 can flexibly control the timing of impurity discharge, improving operational flexibility.

[0029] Example 3:

[0030] Please see Figure 1-4 This utility model provides a technical solution based on Embodiment 1: A flue gas inlet pipe 12 is installed on the left side inside the main flue gas treatment box 2. The bottom output end of the flue gas inlet pipe 12 is located in the filtered water 9. A water inlet pipe 13 and an outlet pipe 14 are respectively provided on the right side inside the main flue gas treatment box 2. The water inlet pipe 13 is located above the filter tank 8, and the outlet pipe 14 is located above the water inlet pipe 13. A collection cover 15 is provided at the output end of the outlet pipe 14, and the output end of the outlet pipe 14 is connected to the auxiliary flue gas treatment device 3.

[0031] Analysis of the above: Flue gas input pump 4 sends flue gas into flue gas input pipe 12. After preliminary purification in filtered water 9, the flue gas is collected by collection hood 15 to expand its range, and then transported to auxiliary flue gas treatment device 3 through extraction pipe 14. Water inlet pipe 13 is used to replenish filtered water 9 to maintain the filtration effect. When the flue gas emission volume is large, it ensures the stable operation of flue gas input pump 4 to meet the transportation requirements. When the filtered water decreases due to evaporation and consumption, filtered water is replenished through water inlet pipe 13. The bottom of flue gas input pipe 12 is deep into the filtered water, so that the flue gas and water are in full contact, and the preliminary filtration effect is more significant. Collection hood 15 expands the flue gas collection range to ensure the subsequent transportation efficiency to the auxiliary device. Water inlet pipe 13 can replenish water in time to ensure the continuous and stable operation of the main flue gas treatment box, and an air pump can also be added at extraction pipe 14 to improve the transportation effect.

[0032] Example 4:

[0033] Please see Figure 1-4 This utility model provides a technical solution based on Embodiment 1: The auxiliary flue gas treatment device 3 includes a filter box 16, a top cover 17, a gas collection hood 19, and an activated carbon filter plate 20. The top cover 17 is installed on the top of the filter box 16, and a discharge pump 21 is installed on the top of the top cover 17. The input end of the discharge pump 21 is located inside the filter box 16, and the output end of the discharge pump 21 is equipped with an exhaust pipe 22. A set of symmetrically distributed support blocks 18 is provided inside the filter box 16. The gas collection hood 19 is installed on the top of the set of support blocks 18, and the activated carbon filter plate 20 is installed on the top of the gas collection hood 19. An insertion port 23 is opened at the bottom left side of the filter box 16.

[0034] Analysis of the above: The flue gas, initially filtered by the main chamber, enters the filter box 16 through the inlet 23. After being collected by the gas collection hood 19, it passes through the activated carbon filter plate 20 for secondary adsorption and purification (removing residual odors, fine particles, and other harmful substances). Finally, the clean gas is discharged by the discharge pump 21 through the outlet pipe 22. When the adsorption capacity of the activated carbon filter plate 20 decreases (e.g., the purification effect weakens), the top cover 17 can be removed to replace the activated carbon filter plate. When it is necessary to accelerate the emission of clean flue gas, the power of the discharge pump 21 can be adjusted. The activated carbon filter plate 20 achieves secondary adsorption, which greatly improves the flue gas purification effect and makes the emitted gas cleaner. The top cover 17 is removable and, together with the support block 18, supports the gas collection hood and the activated carbon filter plate, facilitating the inspection and replacement of internal components. The discharge pump 21 actively discharges the gas to ensure the efficiency of flue gas emission and avoid the retention of purified gas.

[0035] Working principle: The flue gas generated by waste-to-energy is sent to the filter tank 8 of the main flue gas treatment box 2 through the flue gas input pump 4 and flue gas input pipe 12. It comes into full contact with the filtered water 9 to complete the preliminary filtration. At the same time, the motor 25 of the impurity removal device 6 drives the cleaning scraper 29 to rotate and scrape off the impurities attached to the inner wall of the filter tank 8. The flue gas after preliminary filtration enters the auxiliary flue gas treatment device 3 through the collection hood 15 and the extraction pipe 14. It is collected by the gas collection hood 19 in the filter box 16 and then purified by secondary adsorption through the activated carbon filter plate 20. Finally, the clean gas is discharged through the discharge pump 21 and the gas outlet pipe 22. The impurities deposited at the bottom of the filter tank 8 are discharged through the impurity discharge pipe 10 and the impurity conveying pump 5. The filtered water 9 can be replenished through the water inlet pipe 13 to ensure the continuous and stable operation of the device.

The structure and principle of the components, which are common standard parts or known to those skilled in the art, can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this utility model is that some existing waste-to-energy flue gas treatment devices filter impurities in the flue gas by using water in a water tank. However, the impurities are deposited at the bottom of the water tank and attached to the inner wall of the water tank, which makes it inconvenient for workers to clean the bottom and inner wall of the water tank and affects the maintenance of workers. This utility model, through the combination of the above-mentioned components, can use a rotating cleaning scraper to efficiently scrape off the impurities attached to the inner wall of the filter tank, and can also use the impurity discharge pipe and impurity conveying pump to timely discharge the impurities deposited at the bottom of the tank, which greatly improves the convenience of cleaning and maintenance.
