Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1 Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0023] A flue gas purification mechanism for boilers that is convenient for sedimentation, including the first box body 1 and the second box body 2. The bottom end of the first box body 1 is fixedly provided with the first sewage discharge pipe 3. The lower part of one side of the first sewage discharge pipe 3 is fixedly provided with the second sewage discharge pipe 4. The lower part of one side of the first box body 1 is fixedly provided with the air inlet pipe 5. A plurality of baffle plates 6 are fixedly arranged in an array and staggered on the upper inner wall of the first box body 1. The bottom ends of the baffle plates 6 are all fixedly provided with a plurality of atomizing nozzles 7 in an array. The top end of the first box body 1 is fixedly provided with the first air outlet pipe 8. The other end of the first air outlet pipe 8 extends into the second box body 2. The upper part of one side of the second box body 2 is fixedly provided with the second air outlet pipe 9. The middle part of one side of the second box body 2 is fixedly provided with the feeding pipe 10.

[0024] Specifically, as Figures 1-4As shown, a cavity 11 is circumferentially formed inside the upper part of the first box body 1. The inner spaces of the baffle plates 6 communicate with the inner space of the cavity 11. A liquid inlet pipe 12 is fixedly arranged on the upper side of the first box body 1, and the liquid inlet pipe 12 communicates with the inner space of the cavity 11. The cross-section of the inner space of the upper part of the first box body 1 is a rectangular structure, and the cross-section of the inner space of the lower part of the first box body 1 is a circular structure. The water liquid is pumped by a pump body, enters the cavity 11 through the liquid inlet pipe 12, and then is sprayed downward through the baffle plates 6 and the atomizing nozzles 7, so that the particulate impurities in the flue gas can fall to the inner wall of the bottom end of the first box body 1 along with the water liquid, and then can be discharged through the first sewage discharge pipe 3 and the second sewage discharge pipe 4.

[0025] Specifically, as Figures 1-4 shown, a first motor 13 is fixedly embedded in the lower part of the first sewage discharge pipe 3. The output end of the first motor 13 is fixedly connected with a first rotating rod 14. The top end of the first rotating rod 14 extends into the first box body 1. A plurality of connecting rods 15 are fixedly arranged on the upper part of the first rotating rod 14. The other ends of the connecting rods 15 are fixedly connected with a scraping rod 16. The scraping rod 16 abuts against the inner wall of the lower part of the first box body 1. By driving the first rotating rod 14 to rotate by the first motor 13, the first rotating rod 14 drives the connecting rods 15 and the scraping rod 16 to rotate, so that the inner wall of the lower part of the first box body 1 can be cleaned by the scraping rod 16.

[0026] Specifically, as Figures 1-4 shown, a second motor 17 is fixedly arranged at the top end of the second box body 2. The output end of the second motor 17 is fixedly connected with a second rotating rod 18. The bottom end of the second rotating rod 18 extends into the second box body 2. A plurality of stirring rods 19 are symmetrically arranged in an array on the lower part of the second rotating rod 18. An observation window 20 is fixedly embedded through the front side of the second box body 2. By driving the second rotating rod 18 and the stirring rods 19 to rotate by the second motor 17, the flue gas and the reaction liquid can react fully, and the situation inside the second box body 2 can be observed through the observation window 20.

[0027] Example 2 Please refer to Figures 1-4 , the difference between this example and Example 1 is that the inner walls of the bottom ends of the first box body 1 and the second box body 2 are both funnel-shaped structures. By setting the funnel-shaped structures, it is convenient for the waste liquid to be discharged.

[0028] Working principle of the utility model: When in use, flue gas enters the first box body 1 through the air inlet pipe 5. At the same time, the water liquid is pumped by the pump body and enters the cavity 11 through the liquid inlet pipe 12, and then is sprayed downward through the baffle plate 6 and the atomizing nozzle 7. Thus, the particulate impurities in the flue gas can fall to the inner wall at the bottom end of the first box body 1 along with the water liquid, and then can be discharged through the first sewage pipe 3 and the second sewage pipe 4. During this process, a certain amount of water liquid is always maintained in the lower part of the first box body 1, so as to effectively prevent the flue gas from being discharged through the first sewage pipe 3 and the second sewage pipe 4. The first motor 13 drives the first rotating rod 14 to rotate, and the first rotating rod 14 drives the connecting rod 15 and the scraping rod 16 to rotate. Thus, the inner wall of the lower part of the first box body 1 can be cleaned by the scraping rod 16. The flue gas after spraying will enter the second box body 2 through the first air outlet pipe 8. At this time, the second motor 17 drives the second rotating rod 18 and the stirring rod 19 to rotate, so that the flue gas can fully react with the reaction liquid. The situation inside the second box body 2 can be observed through the observation window 20. The flue gas after the reaction will be discharged through the second air outlet pipe 9. The reaction liquid can be added into the second box body 2 through the feeding pipe 10. The used reaction liquid can be discharged through the pipeline at the bottom end of the second box body 2.

[0029] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
