[0002] Desulfurization equipment generally refers to a series of equipment used in the production of the power industry to remove sulfur elements in coal and prevent the generation of SO2 during combustion. Sulfur causes relatively large pollution to the environment. The pollution of sulfur oxides and hydrogen sulfide to the atmosphere, and the pollution of sulfates and hydrogen sulfide to water bodies are the key points of environmental protection work.

Through the desulfurization waste gas purification device of the utility model, not only can sulfides in the waste gas be removed by the treatment liquid, but also the mud adhered to the inner wall of the treatment device can be cleaned cleanly and thoroughly, conveniently keeping the device clean.

[0004] Although the above scheme can remove sulfides in the waste gas through the treatment liquid and can also clean the mud adhered to the inner wall of the treatment device cleanly and thoroughly, the desulfurization and purification device in the above patent is difficult to reduce dust emissions. Generally, a large amount of dust is mixed in the flue gas, affecting the smooth progress of desulfurization and purification work. For this reason, we provide a desulfurization and purification device for reducing dust emissions to solve the above problems. Content of the Utility Model

The material of the inner surface of the inlet flue bottom plate of the desulfurization equipment body 1 is Q235B + C276 alloy composite plate. The platform, ladder railing grille is made of Q235B + hot dip galvanized. The material of the demister cleaning water pipe is PP, the material of the demister cleaning nozzle is PP, the material of the oxidation air pipe is 1.4529, the material of the demister is flame - retardant PP, and the material of the internal filter screen is 1.4529.

[0027] Please refer to Figure 1 , on both sides of the dust absorption housing 2, L - shaped support plates 19 are fixedly arranged respectively. There are two groups of L - shaped support plates 19 in total. The bottoms of the two groups of L - shaped support plates 19 are fixedly connected to the upper surface of the external installation bottom plate 20. The purpose of setting multiple groups of L - shaped support plates 19 is to effectively support the dust absorption housing 2 and ensure its stability during operation.

[0028] Please refer to Figure 1 , the external installation bottom plate 20 is provided with expansion screw holes 21. There are ten groups of expansion screw holes 21 in total. The ten groups of expansion screw holes 21 are evenly distributed on the external installation bottom plate 20. The cooperation between the external installation bottom plate 20 and the expansion screw holes 21 can install this desulfurization and purification equipment through expansion screws and ensure its stability after installation.

[0029] Please refer to Figure 1 and Figure 4 , the upper surface of the external installation bottom plate 20 is fixedly connected to the bottom of the desulfurization equipment body 1. A heating protection housing 16 is connected and arranged between the desulfurization equipment body 1 and the dust absorption housing 2. The setting of the heating protection housing 16 can effectively ensure the temperature of the flue gas in its inner space. A copper heating pipe 17 is fixedly arranged inside the heating protection housing 16. The setting of the copper heating pipe 17, using the characteristic of copper's heat conduction, can effectively heat the liquid inside it. The special design shape extends the path of the liquid flow and can enhance the heating effect.

[0030] Please refer to Figure 1 and Figure 4 , both ends of the copper heating pipe 17 are connected and provided with second external pipelines 18. There are two groups of second external pipelines 18 in total. The two groups of second external pipelines 18 are respectively fixed on both sides of the heating protection housing 16. The setting of the two groups of second external pipelines 18 facilitates the connection with the external water pipe and keeps the liquid in the copper heating pipe 17 in a flowing state all the time.

[0031] Please refer to Figure 2 and Figure 3, the outer circumferential surface of the dust absorption housing 2 is connected to one end of the smoke passage pipe 8. A support and positioning module 11 is fixedly arranged at the top of the smoke passage pipe 8. A linkage limiting rod 12 is rotatably arranged inside the support and positioning module 11. The arrangement of the support and positioning module 11 can effectively support the linkage limiting rod 12 and ensure the fixed-point rotation of the linkage limiting rod 12.

[0032] Please refer to Figure 3 , the linkage limiting rod 12 contacts the support and restriction module 14. A restricted moving plate 15 is rotatably arranged inside the support and restriction module 14. The restricted moving plate 15 contacts the linkage limiting rod 12. The close cooperation among the support and restriction module 14, the restricted moving plate 15, and the linkage limiting rod 12 can effectively ensure the stability of the linkage limiting rod 12, making it not easy for the linkage limiting rod 12 to separate from other components.

[0033] Please refer to Figure 3 , a rigid rubber pad 13 is fixedly arranged at the bottom of the linkage limiting rod 12. The bottom of the rigid rubber pad 13 contacts the top of the filter carbon plate 10. The arrangement of the rigid rubber pad 13 can effectively press the filter carbon plate 10 under the action of external pressure and, through the reaction force, cause a certain degree of deformation of the rigid rubber pad 13 itself, thereby ensuring the stability of the filter carbon plate 10.

[0034] Please refer to Figure 2 , the filter carbon plate 10 is inserted into the inside of the smoke passage pipe 8. The arrangement of the filter carbon plate 10 can initially filter the flue gas, filter most of the dust, and ensure that the dust doped in the flue gas is greatly reduced.

[0035] Please refer to Figure 2 , the other end of the smoke passage pipe 8 is connected to a first external pipe 9. An inlet valve 3 and an outlet valve 4 are connected to the outer circumferential surface of the dust absorption housing 2. The arrangement of the inlet valve 3 and the outlet valve 4 can effectively ensure the free entry and exit of water into and out of the dust absorption housing 2, and a certain amount of water will be stored at the bottom of the dust absorption housing 2.

[0036] Please refer to Figure 1 and Figure 2 , a unidirectional DC motor 5 is fixedly arranged on one side of the dust absorption housing 2. The unidirectional DC motor 5 is a prior art and will not be elaborated too much. The arrangement of the unidirectional DC motor 5 can effectively provide sufficient power support for the rotation of other components. The output rotating shaft of the unidirectional DC motor 5 is fixedly connected to one end of a linkage bearing 6. A rain shower plate 7 is fixedly arranged on the outer circumferential surface of the linkage bearing 6. The arrangement of the rain shower plate 7 can effectively stir the water stored at the bottom of the dust absorption housing 2, keep the rain shower plate 7 always wet, and thus adsorb the dust in the flue gas again, thereby ensuring the cleanliness of the flue gas.

[0037] Working principle: The external flue gas enters the flue gas pipeline 8 through the first external pipeline 9. First, the flue gas passes through the filter carbon plate 10. Under the action of the filter carbon plate 10, a large amount of dust in the flue gas is filtered. Subsequently, the flue gas enters the dust absorption housing 2. At this time, the unidirectional DC motor 5 is started to work, driving the rain plate 7 on the linkage bearing 6 to rotate in place. The rotation of the rain plate 7 is intermittent and continuously stirs the water stored at the bottom of the dust absorption housing 2, using the water body to adsorb the dust mixed in the flue gas again, so as to ensure the cleanliness of the flue gas. The flue gas enters the heating protection housing 16. At this time, the heating protection housing 16 is in a relatively closed space, enabling the flue gas to be discharged only at the designated position, making the temperature in the heating protection housing 16 relatively high, and continuously heating the water body in the copper heating pipe 17, thus achieving the effect of energy reuse. Finally, the flue gas enters the desulfurization equipment body 1 to complete the desulfurization and purification operation, which can effectively reduce the dust emission and ensure that the dust will not accumulate in the desulfurization equipment body 1, enhancing the flue gas purification rate.
