[0021] Please see Figure 1-3 This utility model provides a technical solution: a flue gas environmental protection dust removal and desulfurization device, comprising:

[0022] Dust removal and desulfurization frame 1;

[0023] The dust removal and desulfurization structure is located inside the dust removal and desulfurization frame 1;

[0024] The dust removal and desulfurization structure includes multiple smoke pipes 2, fixed smoke pipes 3, and fixed water pipes 5. One end of each smoke pipe 2 is connected to the dust removal and desulfurization frame 1 at equal intervals along the circumference surface. The other end of each smoke pipe 2 is connected to the fixed smoke pipe 3 at equal intervals along the circumference surface. The outer walls of the smoke pipes 2 are fixedly embedded in the dust removal and desulfurization frame 1. The upper surface of the outer wall of the fixed smoke pipe 3 is fixedly embedded in the dust removal and desulfurization frame 1. The lower surface of the outer wall of the fixed water pipe 5 is fixedly embedded in the fixed smoke pipe 3. Multiple connecting pipes 6 are connected at equal intervals along the circumference surface at the top of the outer wall of the fixed water pipe 5. Spraying rings 7 are connected to the ends of the multiple connecting pipes 6 that are far apart from each other. The inner wall of the spraying rings 7 is fixedly sleeved on the fixed smoke pipe 3.

[0025] In this implementation plan: the coal smoke in the dust removal and desulfurization frame 1 is dispersed and absorbed through multiple smoke pipes 2, the lime slurry is transported to the top by fixed water pipes 5, and then transported to the spray ring 7 by multiple connecting pipes 6. The spray ring 7 atomizes the lime slurry under pressure. When the coal smoke in the dust removal and desulfurization frame 1 flows into the multiple smoke pipes 2, it is chemically reacted.

[0026] Specifically, a collection frame 8 is fixedly embedded in the inner wall of the dust removal and desulfurization frame 1, and multiple outflow holes 9 are opened at equal intervals along the circumferential surface.

[0027] In this embodiment: the chemical liquid reacted in the dust removal and desulfurization frame 1 can be collected by the collection frame 8 and flowed out through multiple outflow holes 9.

[0028] Specifically, an auxiliary frame 10 is fixedly fitted on the outer wall of the dust removal and desulfurization frame 1, and multiple extension frames 11 are provided at equal intervals along the circumferential surface of the bottom of the outer wall of the auxiliary frame 10.

[0029] In this embodiment, the auxiliary frame 10 allows the outflowing chemical liquid to flow further along multiple extension frames 11 for processing.

[0030] Specifically, a filter cotton body 4 is fixedly embedded in the inner wall of the fixed flue 3, and the inner wall of the filter cotton body 4 is fixedly sleeved on the fixed flue 3.

[0031] In this embodiment, the gas inside the multiple smoking tubes 2 is further filtered by the filter cotton body 4.

[0032] Specifically, a fan frame 12 is fixedly embedded in the top of the inner wall of the fixed flue 3, and a fan motor 15 is installed on the inner wall of the fan frame 12.

[0033] In this embodiment, the fan motor 15 can be fixed by the fan frame 12. When the fan motor 15 is powered on, the output end drives the blades to rotate, thereby causing the air in the fixed flue 3 to flow outward.

[0034] Specifically, multiple support rods 13 are fixed at equal intervals along the circumferential surface of the top of the fixed flue 3, and a protective cover 14 is fixedly installed at the top of the multiple support rods 13.

[0035] In this embodiment, the protective cover 14 can be fixed above the fan motor 15 by multiple support rods 13 to protect the fan motor 15.

[0036] In operation, multiple smoke pipes 2 disperse and absorb the coal smoke within the dust removal and desulfurization frame 1. A fixed water pipe 5 transports lime slurry to the top, where it is then conveyed to the spray ring 7 via multiple connecting pipes 6. The spray ring 7 atomizes the lime slurry under pressure, causing the coal smoke within the dust removal and desulfurization frame 1 to undergo a chemical reaction as it flows into the multiple smoke pipes 2. A collection frame 8 collects the reacted chemical liquid within the dust removal and desulfurization frame 1 and allows it to flow out through multiple outlet holes 9. An auxiliary frame 10 further allows the outflowing chemical liquid to flow along multiple extension frames 11 for further processing. A filter cotton body 4 further filters the multiple smoke pipes. The gas inside the flue pipe 2 is fixed by the fan frame 12, which can fix the fan motor 15. When the fan motor 15 is powered on, the output end drives the blades to rotate, thereby causing the air inside the fixed flue pipe 3 to flow outward. Multiple support rods 13 can fix the protective cover 14 above the fan motor 15 to protect the fan motor 15. The spray can be used to adsorb sulfur dioxide and dust particles in the coal smoke. The spray atomizes the lime slurry into fine droplets, which fully contact and react with sulfur dioxide and dust in the flue gas to achieve efficient desulfurization and dust removal. The structure is relatively simple, occupies a small area, operates stably, and has low maintenance costs.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
