These harmful substances may include particulate matter, sulfur dioxide, nitrogen oxides, and volatile organic compounds. In order to capture and remove particulate matter from flue gas while reducing energy consumption, improving energy efficiency, and lowering production costs, high-efficiency demisting devices are required for flue gas treatment.

[0003] During the use of high-efficiency demisting devices for traditional flue gas treatment, a certain amount of acid mist is entrained in the flue gas, which needs to be absorbed by ionic liquid to form heat-stable salt. A high-efficiency electric demisting device is added after the washing tower to effectively control the acid mist in the flue gas from entering the ionic liquid. However, the electric demisting device is not easy to clean after being used for too long, and the operator needs to enter the pipeline to clean it manually, which is inconvenient.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 1 - Figure 3 , the utility model provides an embodiment: a high-efficiency demisting device for flue gas treatment, comprising a shell 1, a smoke inlet pipe 2 is fixedly connected to the inside of the shell 1, a smoke outlet pipe 3 is fixedly connected to the inside of the shell 1, a motor 4 is fixedly connected to the top of the shell 1, a threaded rod 5 is fixedly connected to the output end of the motor 4, the outer wall of the threaded rod 5 is threadedly connected to a sleeve 8, the outer wall of the sleeve 8 is fixedly connected to a support rod 10, one end of the support rod 10 is fixedly connected to a sleeve 2 9, a limiting component is provided inside the shell 1, an electric demisting device 7 is provided inside the shell 1, a support plate 11 is provided on one side of the support rod 10, a scraper 12 is fixedly connected to one side of the support plate 11, and one side of the scraper 12 is attached to the outer wall of the electric demisting device 7, the limiting component comprises a limiting rod 6, both ends of the limiting rod 6 are fixedly connected to the inside of the shell 1, and the inside of the sleeve 2 9 is slidably connected to the outer wall of the limiting rod 6;

[0031] Specifically, when the electrostatic demister 7 needs to be cleaned, the output end of the motor 4 starts operating, driving the threaded rod 5 to rotate. The threaded rod 5 is tightly coupled to the sleeve 1 8, so as it rotates, the sleeve 1 8 moves up and down along the axis of the threaded rod 5. During this process, the support rod 10 is connected to the sleeve 1 8, and therefore the support rod 10 also descends. The other end of the support rod 10 is connected to the limit rod 6 via the sleeve 2 9. The limit rod 6 serves as a guide and limiter, ensuring that the support rod 10 remains stable during movement and does not deviate from the predetermined trajectory. When the support rod 10 descends, the sleeve 2 9 slides smoothly and smoothly on the outer wall of the limit rod 6, ensuring the stability and accuracy of the entire cleaning process. As the support rod 10 descends, the scraper 12 connected to it also moves into the interior of the electrostatic demister 7. The material and shape of the scraper 12 have been carefully designed and selected to effectively remove dust and dirt accumulated inside the electrostatic demister 7. When the scraper 12 contacts the inner wall of the electric demisting device 7, it moves along the inner wall to scrape off and clean the dirt attached to it.

[0032] Reference Figure 3 and Figure 4 , one side of the support rod 10 is fixedly connected to a connecting column 13, and the connecting column 13 is internally slidably connected to a limit plate 15, and one side of the limit plate 15 is fixedly connected to a connecting column 2 14, and one end of the connecting column 2 14 is fixedly connected to the other side of the support plate 11, and a telescopic rod 17 is provided inside the connecting column 13, and one end of the telescopic rod 17 is fixedly connected to the inside of the connecting column 13, and the other end of the telescopic rod 17 is fixedly connected to the other side of the limit plate 15, and a spring 18 is sleeved on the outer wall of the telescopic rod 17, and one end of the spring 18 is fixedly connected to the other end of the limit plate 15, and the other end of the spring 18 is fixedly connected to the inside of the connecting column 13, and a sealing ring 16 is fixedly connected to the inside of the connecting column 13, and the inner wall of the sealing ring 16 is fitted to the outer wall of the connecting column 2 14, and a cleaning door 19 is rotatably connected to the inside of the shell 1;

[0033] Specifically, in order to ensure that the scraper 12 can still fit tightly on the defogging device 7 after aging, the tension of the spring 18 is used to support the limit plate 15. This design not only ensures the stability and durability of the scraper 12, but also through the elastic adjustment of the spring 18, the scraper 12 can maintain a tight fit with the defogging device 7 under different circumstances. This fit not only improves the defogging effect, but also helps to reduce equipment wear and failure. The limit plate 15 is limited inside the connecting column 13 through the connecting column 2 14. This design cleverly realizes the positioning and fixation of the scraper 12. At the same time, the connecting column 2 14 generates pressure on the scraper 12 through the support plate 11, so that the scraper 12 always fits tightly on the defogging device 7. This pressure distribution is uniform, which avoids deformation and loosening of the scraper 12 during operation. In addition, in order to ensure the cleanliness of the inside of the connecting column 13 and the safety of parts, a sealing ring 16 is provided between the connecting column 2 14 and the connecting column 13. This design can effectively prevent dust from entering the interior of the connecting column 13, thereby avoiding damage and wear of internal parts. At the same time, the sealing ring 16 also has good sealing performance, ensuring that the fit between the scraper 12 and the electrostatic demisting device 7 is not affected by the external environment. In terms of cleaning, when the dust generated by the scraper 12 during the cleaning process falls to the bottom of the shell 1, a convenient cleaning method is designed. Simply manually open the cleaning door 19 to easily clean the dust inside the shell 1. This design not only simplifies the cleaning process, but also improves work efficiency.

[0034] Working principle: When using the high-efficiency demisting device for flue gas treatment, first of all, it is necessary to clean the electric demisting device 7. The output end of the motor 4 drives the threaded rod 5 to rotate. The threaded rod 5 drives the support rod 10 to descend through the sleeve 1 8. The other end of the support rod 10 is limited on the outer wall of the limit rod 6 through the sleeve 2 9. The support rod 10 cleans the electric demisting device 7 through the scraper 12. In order to prevent the scraper 12 from being unable to fit on the electric demisting device 7 after aging, the scraper 12 is tightened to the limit plate 1 through the tension of the spring 18. 5 is supported, the limit plate 15 is limited inside the connecting column 13 through the connecting column 2 14, and the connecting column 2 14 generates pressure on the scraper 12 through the support plate 11, so that the scraper 12 can always fit tightly on the electric demisting device 7, and the connecting column 2 14 and the connecting column 1 13 are sealed by the sealing ring 16, which can prevent dust from entering the interior of the connecting column 13 and causing damage to the internal parts. The dust cleaned then falls to the bottom of the shell 1, and it only needs to manually open the cleaning door 19 for unified cleaning.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
