[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figures 1 to 3The utility model provides an embodiment: a boiler out-of-stock circulation treatment device, comprising a reaction tank 11, a second motor 12 is fixedly connected to one side of the outer wall of the reaction tank 11, a rotating shaft 15 is fixedly connected to the output end of the second motor 12, an eccentric wheel 16 is fixedly connected to the outer wall of the rotating shaft 15, a dust collecting plate 17 is fixedly connected to the outer wall of the eccentric wheel 16, a fixed block 18 is fixedly connected to the outer wall of the dust collecting plate 17, a slide groove is provided inside the reaction tank 11, the outer wall of the fixed block 18 is slidably connected to the inner wall of the slide groove, a second spring 28 is fixedly connected to the outer wall of the fixed block 18, one end of the second spring 28 is fixedly connected to the inside of the reaction tank 11, a cleaning component is arranged inside the reaction tank 11, the cleaning component comprises a hydraulic rod 19, one side of the outer wall of the reaction tank 11 is fixedly connected to the inner wall of the hydraulic rod 19, a scraper 20 is fixedly connected to the output end of the hydraulic rod 19, and the outer wall of the scraper 20 is in contact with the inner wall of the reaction tank 11.

[0026] Specifically, when the second motor 12 is started, its output end drives the rotating shaft 15 to rotate. The eccentric wheel 16 fixed on the outer wall of the rotating shaft 15 rotates accordingly. Due to its eccentric design, it can convert the rotational power into reciprocating power. The dust collecting plate 17 driven by the eccentric wheel 16 reciprocates inside the reaction tank 11. The dust collecting plate absorbs the dust in the reaction tank and the particles in the flue gas through physical contact, effectively removing pollutants. The dust collecting plate 17 is connected to the slide groove in the reaction tank through the fixed block 18, and the outer wall of the fixed block 18 is installed with a second spring 28. This design enables the dust collecting plate to be adaptively adjusted under the drive of the eccentric wheel 16, maintaining close contact with the inner wall of the reaction tank 11, and maintaining high dust collection efficiency even when the internal conditions of the reaction tank 11 change, such as temperature changes that cause the inner wall to expand or contract. The cleaning assembly composed of the hydraulic rod 19 and the scraper 20 is used to remove the dust adsorbed by the dust collecting plate. The action of the hydraulic rod 19 causes the scraper to be pressed against the inner wall of the reaction tank, and the dust and flue gas residue adsorbed on the dust collecting plate 17 are thoroughly cleaned, so as to keep the inside of the device clean, thereby ensuring continuous and efficient desulfurization performance.

[0027] Reference Figures 3 to 5 A collecting tank 31 is provided inside the reaction tank 11, and a storage box 13 is fixedly connected to the lower surface of the reaction tank 11, and the storage box 13 is arranged directly below the collecting tank 31; a first connecting pipe 8 is fixedly connected to the inside of the reaction tank 11, and an adsorption tank 9 is fixedly connected to one end of the first connecting pipe 8, and a first motor 10 is fixedly connected to the upper surface of the adsorption tank 9, and a stirring rod 30 is fixedly connected to the output end of the first motor 10, and a second adsorption layer 14 is fixedly connected to the outer wall of the stirring rod 30; a processing tank 1 is provided on one side of the outer wall of the adsorption tank 9, a multi-layer filter screen 5 is fixedly connected to the inside of the processing tank 1, a first adsorption layer 6 is fixedly connected to the inside of the processing tank 1, an annular pipe 2 is fixedly connected to the inside of the processing tank 1, and a collecting box 4 is provided on one side of the outer wall of the processing tank 1.

[0028] Specifically, the collection tank 31 inside the reaction tank 11 is designed to capture and temporarily store dust and other solid pollutants removed from the flue gas. These pollutants are then collected by the storage box 13 located directly below the collection tank 31, which is convenient for subsequent processing and disposal. The first connecting pipe 8 leading from the reaction tank 11 transmits the flue gas to the adsorption tank 9, wherein the second adsorption layer 14 on the stirring rod 30 driven by the first motor 10 is used to further adsorb harmful substances in the flue gas, such as SOx and NOx. The second adsorption layer 14 is activated alumina, which has good adsorption performance and can also perform some catalytic reactions and catalytic oxidation on its surface to achieve more thorough desulfurization and purification. The treatment tank 1 is equipped with a multi-layer filter screen 5 and a first adsorption layer 6 inside the tank. The first adsorption layer 6 is activated carbon with a high specific surface area, which can effectively adsorb organic pollutants in the flue gas, such as chlorine and hydrogen sulfide, and the annular tube 2. These components work together to achieve deep filtration and adsorption of residual pollutants in the flue gas, ensuring that the flue gas discharged into the environment meets environmental protection standards. The collection box 4 next to the treatment tank 1 is used to collect solid or liquid pollutants that still need to be removed after multi-stage treatment, such as saturated adsorption materials or filter residues, to facilitate regular cleaning and replacement, ensuring the continued efficient operation of the system.

[0029] Reference Figure 1 to Figure 2 A water pipe is fixedly connected to the inside of the collecting box 4, one end of the water pipe is fixedly connected to the first water pump 3, and the output end of the first water pump 3 is fixedly connected to one end of the annular pipe 2; a second water pump 7 is arranged on one side of the outer wall of the processing tank 1, the input end of the second water pump 7 is fixedly connected to the inside of the collecting box 4, the output end of the second water pump 7 is fixedly connected to the circulation pipe 29, and one end of the circulation pipe 29 is fixedly connected to the inside of the processing tank 1.

[0030] Specifically, the inside of the collection box 4 is connected to the first water pump 3 through a water pipe. This design allows the water in the collection box to be pumped to the annular pipe 2, which is arranged inside the treatment tank 1 and can be used to further dilute or cool the flue gas or pollutants in the treatment tank, improve the treatment efficiency, and recycle the pollutants: the second water pump 7 draws water from the collection box 4 and transports it back to the inside of the treatment tank 1 through the circulation pipe 29. This cycle not only reduces the consumption of water resources, but also can reintroduce some of the pollutants that have not been completely treated into the treatment process through recycling, thereby improving the thoroughness of the treatment.

[0031] Reference Figure 4A bracket 22 is fixedly connected to one side of the outer wall of the adsorption tank 9, a feed plate 21 is fixedly connected to the upper surface of the bracket 22, a second connecting pipe 23 is fixedly connected to the inside of the feed plate 21, a connecting plate 26 is fixedly connected to one side of the outer wall of the adsorption tank 9, a push plate 24 is slidably connected to the inside of the connecting plate 26, a first spring 25 is fixedly connected to the inside of the connecting plate 26, one end of the first spring 25 is fixedly connected to one side of the outer wall of the push plate 24, a guide tube 27 is fixedly connected to the inside of the connecting plate 26, and one end of the guide tube 27 is fixedly connected to the inside of the adsorption tank 9.

[0032] Specifically, the feed plate 21 on the bracket 22 is designed to store the catalyst, wherein the catalyst is: an iron-based catalyst is used to promote the oxidation reaction of sulfide in the flue gas, and convert it into sulfate or sulfuric acid that is easy to remove. At the same time, the iron-based catalyst is relatively low in cost and has a high catalytic activity, and the second connecting pipe 23 is responsible for transporting the catalyst from the feed plate to the adsorption tank 9. This design allows the catalyst to be added automatically and continuously or intermittently, and the frequency and amount of addition are adjusted according to the processing requirements. The push plate 24 and the first spring 25 of the device inside the connecting plate 26 achieve a reciprocating effect to achieve a quantitative effect of the catalyst. When the catalyst is fed in through the second connecting pipe 23, the push plate 24 is subjected to the pressure of the catalyst and moves forward or backward with the help of the elastic force of the first spring 25, thereby controlling the flow and dispersion of the catalyst. The setting of the guide pipe 27 ensures that the catalyst can be effectively guided to a specific position of the adsorption tank 9. This precise guiding and dispersion mechanism ensures that the catalyst can be evenly distributed in the adsorption tank 9, maximizing the use efficiency and desulfurization effect of the catalyst.

[0033] Working principle: First, the flue gas enters the interior of the treatment tank 1, and then undergoes preliminary adsorption through the first adsorption layer 6 (the first adsorption layer 6 is activated carbon, which has a high specific surface area and can effectively adsorb organic pollutants in the flue gas, such as chlorine and hydrogen sulfide) arranged inside the treatment tank 1. The water in the collection box 4 is extracted through the first water pump 3, and the flue gas in the treatment tank 1 is subjected to dust reduction and cooling treatment through the annular pipe 2. At this time, the sewage after dust reduction treatment is subjected to multi-layer filtration through the filter net 5 (the filter net 5 is: activated carbon fiber cloth, which has an adsorption effect in addition to the physical filtration effect and can effectively remove harmful chemicals in the gas), thereby treating the sewage, and then the filtered sewage is extracted to the collection box 4 through the second water pump 7. The inside of the adsorption tank 9 forms a closed loop, which achieves the effect of water circulation, reduces the demand for external water resources, and realizes the reprocessing of pollutants generated in the flue gas treatment process, thereby improving the treatment efficiency and environmental protection. At this time, the flue gas enters the inside of the adsorption tank 9 through the first connecting pipe 8. When it is necessary to add a catalyst to destock the flue gas, the catalyst is first released from the inside of the feed plate 21, and then the first spring 25 is squeezed by pushing 24, so that the perforation inside 24 corresponds to the second connecting pipe 23, thereby realizing the precise control of the amount of catalyst added. At this time, the second adsorption layer 14 is rotated by rotating the output end of the first motor 10 (the second adsorption layer 14 is activated alumina, which has good adsorption performance). , and some catalytic reactions can also be carried out on its surface), increasing the contact surface with the flue gas, thereby achieving the effect of denitrification of the flue gas. The first motor 10 drives the stirring rod 30 and the second adsorption layer 14 to disperse the catalyst, so that the iron-based catalyst and the flue gas undergo chemical adsorption reaction, and further remove the SOx and NOx harmful gases in the flue gas. The flue gas that has undergone multiple denitrification treatments enters the interior of the reaction tank 11, and the output end of the second motor 12 is started to drive the rotating shaft 15 and the eccentric wheel 16 thereon to rotate, so that the dust collecting plate 17 is reciprocated in the interior of the reaction tank 11 through the fixed block 18. (The dust collecting plate 17 is made of polytetrafluoroethylene (PTFE), which has excellent high temperature resistance and chemical corrosion resistance, and is not easy to adhere to substances on the surface, which is conducive to removing adhered dust and The particles can provide a larger surface area, which helps to capture more dust and particles, while maintaining good air circulation performance and adsorbing dust and other solid particles in the flue gas through physical contact). When the pollutants collected on the dust collecting plate 17 are stretched by the reciprocating motion and the second spring 28 to the dust collecting plate 17, a small vibration is generated, so that the dust on the dust collecting plate 17 can be cleaned. Finally, the dust is collected on the inner wall of the reaction tank 11, and the scraper 20 is pushed and retracted at the output end of the hydraulic rod 19, thereby interfering with the dust falling through the collection groove 31 into the storage box 13 below, which is convenient for subsequent processing and cleaning. The above design ensures the cleanliness of the inner wall of the reaction tank 11 and maintains the dust collection efficiency.
