[0002] The post-treatment stage of waste incineration involves purifying the flue gas by passing it through a dust removal system, and then discharging the compliant gas through a chimney.

When in use, the structure releases ash into the degradation chamber through the ash hopper, and then the temperature controller is turned on to maintain a suitable temperature. The heavy metal pollutants in the ash are removed by biodegradation. However, the structure is not easy to filter flue gas during use, and the biodegradation process takes a long time, resulting in low flue gas treatment efficiency. Utility Model Content

At the same time, the high-temperature flue gas can also dissipate heat through the heat dissipation fin cylinder, reducing the heat when it is discharged. After the flue gas is cooled by the heat dissipation fin cylinder, it is transported to the protective shell. The first and second gathering bodies gather the flue gas, and it can also be filtered through the filter plate to remove impurities from the flue gas, making the flue gas discharge more environmentally friendly. Meanwhile, the high-pressure water tank delivers the desulfurization medium to the second collector body through the atomizing nozzle.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] As attached Figure 1 - Figure 6The waste incineration flue gas environmental protection treatment system shown in the figure uses a flow guiding component on the treatment cylinder 1. The flow distribution plate 3 diverts the flue gas through the heat dissipation fin cylinder 4 for filtration. At the same time, the high-temperature flue gas can also dissipate heat through the heat dissipation fin cylinder 4, reducing the heat during discharge. After the flue gas is cooled by the heat dissipation fin cylinder 4, it is transported into the protective shell 5. The flue gas is gathered by the first gathering body 6 and the second gathering body 8. At the same time, the flue gas can also be filtered by the filter plate 7 to remove impurities from the flue gas, making the flue gas discharge more environmentally friendly. Meanwhile, the high-pressure water tank 10 transports the desulfurization medium to the second gathering body 8 through the atomizing nozzle 9. The desulfurization medium comes into contact with the flue gas to desulfurize the flue gas, making the flue gas discharge more environmentally friendly. When the flue gas is transported to the first gathering body 6 and the second gathering body 8 after being filtered by the filter plate 7, the flue gas gathers at the top of the inner cavity of the second gathering body 8 so that the desulfurization medium can fully contact the flue gas. At the same time, the flue gas can also be filtered again by each diversion filter 13 before being discharged, making the flue gas discharge more environmentally friendly. The specific structural settings of the components are as follows. The flow guiding and processing assembly includes a protective cylinder 2 set at the top of the processing cylinder 1, a flow distribution plate 3 set at the bottom of the inner wall of the processing cylinder 1, a heat dissipation fin cylinder 4 for filtering set at the flow distribution plate 3, and a protective shell 5 installed at the top of the heat dissipation fin cylinder 4 by bolts. The top of the inner cavity of the protective shell 5 is provided with a first gathering body 6 for gathering flue gas, the bottom of the first gathering body 6 is provided with a filter plate 7 for filtering flue gas, the outside of the first gathering body 6 is covered with a second gathering body 8, and an atomizing nozzle 9 for guiding flow is fixedly provided on one side of the surface of the second gathering body 8. The atomizing nozzle 9 penetrates the protective cylinder 2 and extends to the outside of the protective cylinder 2. A high-pressure water tank 10 is provided on the atomizing nozzle 9. The top of the protective cylinder 2 is embedded with a limiting sleeve 11, and a reinforcing ring 12 is internally threaded to the limiting sleeve 11. A diversion filter element 13 is fixedly installed in the middle of the reinforcing ring 12. A column 14 is bolted to the middle of the protective shell 5. The top of the column 14 extends to the bottom of the filter element plate 7. A first conduit 15 is provided on the outside of the protective cylinder 2. The top of the first conduit 15 passes through the protective cylinder 2 and the protective shell 5 in sequence and extends into the protective shell 5 and communicates with the protective shell 5. The bottom of the first conduit 15 passes through the treatment cylinder 1 and extends to the diversion plate 3 and communicates with the diversion plate 3. A second conduit 16 for guiding the flue gas is provided at the bottom of the treatment cylinder 1.

[0017] When using the above structure, the staff will install the device at the designated location. When the flue gas from the waste incineration is being treated, the flue gas is transported to the treatment cylinder 1 through the second duct 16, and then diverted by the diverting plate 3 and filtered through the heat dissipation fin cylinder 4. At the same time, the high-temperature flue gas can also dissipate heat through the heat dissipation fin cylinder 4, reducing the heat when it is discharged. After the flue gas is cooled by the heat dissipation fin cylinder 4, it is transported to the protective shell 5, where the first gathering body 6 and the second gathering body 8 gather the flue gas. At the same time, the flue gas can also be filtered through the filter plate 7 to remove impurities from the flue gas, making the flue gas discharge more environmentally friendly. Meanwhile, the high-pressure water tank 10 delivers the desulfurization medium to the second gathering body 8 through the atomizing nozzle 9. The desulfurization medium comes into contact with the flue gas to desulfurize it, making the flue gas discharge more environmentally friendly. After the flue gas is filtered by the filter plate 7, it is delivered to the first gathering body 6 and the second gathering body 8. The flue gas gathers at the top of the inner cavity of the second gathering body 8 so that the desulfurization medium can fully contact the flue gas. At the same time, the flue gas can also be filtered again by each diversion filter element 13 before being discharged, making the flue gas discharge more environmentally friendly.

[0018] Unlike existing technologies, this application discloses a waste incineration flue gas environmental protection treatment system. The diversion plate 3 diverts the flue gas through a heat dissipation finned cylinder 4 for filtration. Simultaneously, the high-temperature flue gas can also dissipate heat through the heat dissipation finned cylinder 4, reducing heat during discharge. After cooling by the heat dissipation finned cylinder 4, the flue gas is transported to the protective shell 5, where it is gathered by the first gathering body 6 and the second gathering body 8. It also passes through a filter plate 7 to filter impurities, making the flue gas discharge more environmentally friendly. Meanwhile, a high-pressure water tank 10 delivers desulfurization medium through an atomizing nozzle 9 to the second gathering body 8. The desulfurization medium contacts the flue gas to desulfurize it, making the flue gas discharge more environmentally friendly. After being filtered by the filter plate 7, the flue gas is transported to the first gathering body 6 and the second gathering body 8, where it gathers at the top of the inner cavity of the second gathering body 8 to ensure sufficient contact between the desulfurization medium and the flue gas. Furthermore, the flue gas can be further filtered by each diversion filter element 13 before discharge, making the flue gas discharge more environmentally friendly.

[0019] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
