[0002] Dust settling devices purify gases and prevent air pollution by allowing dust particles in exhaust gases to settle naturally under gravity. Traditional dust settling devices are only suitable for capturing dust particles larger than 50μm due to their low dust removal efficiency, while fine particles have a long settling time due to their slow settling speed.

Combined with an atomizing spray assembly, it achieves the effect of a fog cannon, ensuring thorough mixing and contact between the waste gas and atomized water. Simultaneously, the gas is blocked by a blocking assembly, causing the pressurized droplets to explode and splash upon contact with the blocking assembly, further increasing the adhesion of dust in the waste gas and thus increasing the settling rate of fine particles.

[0018] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0019] according to Figures 1-5As shown, this embodiment proposes a dust settling spray device for preventing air pollution, including a settling chamber 1, which is a tubular structure. The settling chamber 1 has a hemispherical input end 2 and an output end 3 at its two ends. An air inlet pipe 4 is provided on the input end 2, and an exhaust pipe 5 is provided on the output end 3. A collection chamber 6 supporting the settling chamber 1 is also provided at the bottom of the settling chamber 1. An air blowing mechanism is provided inside the settling chamber 1 near the input end 2. An atomizing spray assembly is provided at the output end 3 of the air blowing mechanism. A blocking component to increase gas residence time is provided on one side of the atomizing spray assembly, and a settling component for water mist settling is provided on one side of the blocking component. An air supply mechanism is also provided inside the settling chamber 1 near the output end 3.

[0020] The air blowing mechanism includes a pipe shell 7, a first support base 8, and a first fan 9. The first fan 9 is an axial flow fan, and a drive power supply is pre-embedded in the first support base 8. The first support base 8 is fixed by welding to the inner wall of the settling chamber 1, and the drive power supply is connected to an external power supply through the pipe wall of the settling chamber 1. The first support base 8 is installed at the input end 2 of the pipe shell 7, and the first fan 9 is installed on the first support base 8. The output end 3 of the first fan 9 faces the side of the blocking component.

[0021] Both ends of the tube shell 7 are funnel-shaped, and the middle section of the tube shell 7 is frustoconical. The end with the larger inner diameter of the middle section of the tube shell 7 faces the first fan 9.

[0022] During the settling process, the device inputs exhaust gas through the inlet pipe 4 and discharges the settled gas through the exhaust pipe 5. The blower mechanism draws in the incoming exhaust gas and then discharges it. In conjunction with the atomizing spray assembly, it achieves the effect of a fog cannon, ensuring that the exhaust gas and atomized water are fully mixed and in contact. At the same time, the device is blocked by the blocking assembly, causing the pressurized droplets to explode and splash upon contact with the blocking assembly, further increasing the adhesion of dust in the exhaust gas and thus increasing the settling rate of fine particles.

[0023] The atomizing spray assembly includes a first water supply ring 10, a second water supply ring 11, an atomizing nozzle 12, and a water supply pipe 13. The second water supply ring 11 is provided on the outer side of the first water supply ring 10. The first water supply ring 10 and the second water supply ring 11 are connected. Multiple sets of atomizing nozzles 12 are provided on both the first water supply ring 10 and the second water supply ring 11. The second water supply ring 11 is provided with a water supply pipe 13 that communicates with the outside.

[0024] The inner diameter of the second water conveying ring 11 is larger than the inner diameter of the first water conveying ring 10, and the water conveying pipe 13 penetrates the top wall of the settling chamber 1 and communicates with the outside.

[0025] The blocking assembly includes a first baffle 14, a second baffle 15, and a through hole 16. The first baffle 14 and the second baffle 15 are provided in multiple sets, and the multiple sets of the first baffle 14 and the second baffle 15 are designed to be staggered. The first baffle 14 and the second baffle 15 are provided with through holes 16.

[0026] The first baffle 14 and the second baffle 15 are both formed by three groups of arc-shaped blocks arranged in a circular array, and there is a gap between the first baffle 14 and the second baffle 15.

[0027] The design of multiple sets of first and second baffles repeatedly obstructs the driving force generated by the first fan 9, thereby appropriately reducing the flow speed of the exhaust gas. In each obstruction, the droplets are further explosively splashed, thereby increasing the adsorption of dust in the exhaust gas by the droplets and further enhancing the settling effect of the device.

[0028] The settling assembly includes a first settling plate 17 and a second settling plate 18. Multiple sets of the first settling plate 17 and the second settling plate 18 are provided. There is a gap between the first settling plate 17 and the second settling plate 18. An opening is provided at the bottom of the first settling plate 17 and an opening is provided at the top of the second settling plate 18. Vertically downward grooves 19 are provided on the surfaces of the first settling plate 17 and the second settling plate 18.

[0029] The design of multiple sets of first settling plates 17 and second settling plates 18 is to remove moisture from the exhaust gas after settling, so that dust and water vapor can settle fully, thereby reducing the dust content of the discharged air.

[0030] The air supply mechanism includes a second support base 20 and a second fan 21. The output end 3 of the pipe shell 7 is equipped with the second support base 20, and the second fan 21 is installed on the second support base 20. The output end 3 of the second fan 21 faces the exhaust pipe 5.

[0031] The second fan 21 is designed to appropriately increase the flow of gas during the exhaust phase, thereby increasing the exhaust speed of the gas.

[0032] The collection chamber 6 consists of a sedimentation tank 22, a water storage tank 23, a connecting seat 24, and a water outlet 25. The bottom of the settling chamber 1 is provided with multiple sets of water outlets 25 located below the blocking component and the settling component. The bottom of the settling chamber 1 is provided with a connecting seat 24. The sedimentation tank 22 is located below the connecting seat 24. The water storage tank 23 is located on one side of the sedimentation tank 22, and a sewage pipe 26 is located on the other side. A partition 27 is provided between the water storage tank 23 and the sedimentation tank 22. A water inlet pipe 28 is provided at the upper end of one side of the water storage tank 23, and a water pump connected to the water supply pipe 13 is provided at the lower end of one side of the water storage tank 23. Support plates 29 are provided at both ends of the collection chamber 6, and the top of the support plates 29 is connected to the outer wall of the settling chamber 1.

[0033] In the settling chamber 1, the dust in the exhaust gas is fully adsorbed by the droplets sprayed from the atomizing nozzle 12, making the droplets turbid. Then, the dust settles faster by gravity. At the same time, the settled turbid droplets enter the sedimentation tank 22 through the water outlet 25. After sedimentation, the clarified water can pass through the baffle 27 into the water storage tank 23 for recycling, while the dust settled at the bottom can be discharged through the sewage pipe 26.

[0034] The dust settling spray device for preventing air pollution sends exhaust gas into the air inlet pipe 4, and then through the first fan 9, the exhaust gas is blown into atomized droplets, thereby making the exhaust gas and droplets fully mixed, thus accelerating the settling of dust. The gas then passes through the first baffle plate 14, the second baffle plate 15, the first settling plate 17 and the second settling plate 18, and is then sent to the exhaust pipe 5 by the second fan 21 for discharge.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
