[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a flue gas treatment device with dust reduction function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A flue gas treatment device with dust reduction function includes a housing, an air inlet pipe welded to one outer wall of the housing, an installation plate fixed to the top inner wall of the housing, a T-shaped rod fixed to one outer wall of the installation plate, a filter screen movably connected to the outer wall of the T-shaped rod, the filter screen and an impact assembly working together, a spring installed between one outer wall of the filter screen and one inner wall of the T-shaped rod, a collection groove opened at the bottom of the housing, and a sealing plate fixed to the side wall of the housing.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] A flue gas treatment device with dust reduction function, designed to facilitate the filtration of particulate matter, such as... Figures 1 to 6As shown, the device includes a second housing 5. An air inlet pipe 4 is welded to one outer wall of the second housing 5. An installation plate 17 is fixed to the top inner wall of the second housing 5 by bolts. A T-shaped rod 9 is fixed to one outer wall of the installation plate 17 by screws. A filter screen 8 is slidably connected to the outer wall of the T-shaped rod 9. The filter screen 8 is used in conjunction with the impact assembly. A spring 12 is installed between one outer wall of the filter screen 8 and one inner wall of the T-shaped rod 9. A collection groove 10 is opened at the bottom of the second housing 5. A sealing plate 11 is fixed to the side wall of the second housing 5 by bolts.

[0030] The flue gas to be treated can be input into the second chamber 5 through the air inlet pipe 4. The filter screen 8 is used to filter particulate matter. The impact component can impact the surface of the filter screen 8. After being impacted, the particulate matter trapped on the surface of the filter screen 8 is vibrated and falls into the collection tank 10 for collection. The bottom of the collection tank 10 has a sloping structure, so the particulate matter can slide down the bottom of the collection tank 10. When it is necessary to clean the particulate matter, the sealing plate 11 is removed from the second chamber 5, so that the particulate matter is discharged along the collection tank 10.

[0031] One end of the second box 5 is fixed to the first box 1 by bolts, and an exhaust pipe 6 is welded to the outer wall of one side of the first box 1. A dust suppression component is installed inside the first box 1. The dust suppression component includes a drive motor 2 and a turntable 22. The drive motor 2 is fixed to the top outer wall of the first box 1 by bolts, and the turntable 22 is fixed to the output end of the drive motor 2 by pins. A swing arm 21 is rotatably connected to the bottom of the turntable 22, and a pad 15 is rotatably connected to the bottom of the swing arm 21. An intermediate pipe 23 is fixed to the inner wall of the pad 15 by screws, and a spraying mechanism is installed on the outer wall of the intermediate pipe 23. A hose 3 is installed at one end of the intermediate pipe 23 through a connector.

[0032] After the flue gas is filtered by the filter screen 8, in order to further improve the treatment effect of the flue gas, the hose 3 and the water pump (not shown) are connected. The water pump pressurizes the water and then inputs it into the intermediate pipe 23 through the hose 3. After the spraying mechanism diverts the water, the water is sprayed out through the spraying mechanism to reduce dust in the flue gas.

[0033] The spraying mechanism includes a dust-falling pipe 13, an atomizing nozzle 14, and a rotary joint 16. The rotary joint 16 is installed on the outer wall of the intermediate pipe 23, and the dust-falling pipe 13 is rotatably connected to one end of the rotary joint 16. The atomizing nozzle 14 is connected to the outer wall of the dust-falling pipe 13 through a joint. The inner walls on both sides of the housing 1 are fixed with racks 19 by bolts, and the outer circumference of the dust-falling pipe 13 is fixed with a gear 20 that meshes with the racks 19 by pins.

[0034] The drive motor 2 can drive the turntable 22 to rotate. The swing arm 21 converts the circular motion of the turntable 22 into the linear reciprocating motion of the pad 15 and the intermediate tube 23. During the movement of the intermediate tube 23, the dust-suppressing tube 13 and the atomizing nozzle 14 reciprocate synchronously. At the same time, the rack 19 and the gear 20 enable the dust-suppressing tube 13 to rotate while moving linearly, and the atomizing nozzle 14 to rotate while moving laterally. This can increase the spray range of the atomizing nozzle 14 and improve the dust suppression effect.

[0035] The impact assembly includes an impact plate 18 welded to one end of the intermediate tube 23, and the impact plate 18 and the filter screen 8 are used together.

[0036] The reciprocating motion of the impact plate 18 can reciprocate to impact the filter screen 8. When the impact plate 18 impacts the filter screen 8, the spring 12 is compressed and the filter screen 8 slides along the T-shaped rod 9. When the impact plate 18 and the filter screen 8 separate from each other, the filter screen 8 is reset under the action of the spring 12. Therefore, the filter screen 8 uses vibration to accelerate the falling rate of the particles attached to its surface during the reciprocating motion.

[0037] A drain valve 7 is fixed to one side of the outer wall of the box 1 by bolts;

[0038] The waste liquid after dust removal can be discharged by setting up a drain valve 7.

[0039] Working principle: The flue gas to be treated is input into the second chamber 5 through the intake pipe 4. When the flue gas passes through the filter screen 8, the filter screen 8 filters the particulate matter in the flue gas. When the impact plate 18 reciprocates under the drive of the intermediate pipe 23, it impacts the surface of the filter screen 8. After the filter screen 8 is impacted, the spring 12 is compressed, and the filter screen 8 slides along the T-shaped rod 9, causing the particulate matter filtered and trapped on its surface to fall into the collection tank 10 for collection. The bottom of the collection tank 10 has a sloping structure, and the particulate matter slides down the bottom of the collection tank 10. When it is necessary to clean the particulate matter, the sealing plate 11 is removed from the second chamber 5, and the particulate matter is discharged along the collection tank 10. The flue gas filtered by the filter screen 8 enters the first chamber 1. The hose 3 and the water pump are connected. The system connects to a central pipe 23, where water is pressurized by a water pump and fed through a hose 3. The water is then sprayed out after being diverted by a spraying mechanism to reduce dust in the flue gas. A drive motor 2 drives a turntable 22 to rotate, and a swing arm 21 converts the circular motion of the turntable 22 into the linear reciprocating motion of the pad 15 and the central pipe 23. During the movement of the central pipe 23, the dust-reducing pipe 13 and the atomizing nozzle 14 reciprocate synchronously. Simultaneously, the meshing of the rack 19 and the gear 20 allows the dust-reducing pipe 13 to rotate while moving linearly, and the atomizing nozzle 14 to rotate while moving laterally. This increases the spraying range of the atomizing nozzle 14 and enhances the dust-reducing effect. The waste liquid after dust reduction is discharged through a drain valve 7.

[0040] 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.
