The upper end of the spray tower 2-1 is provided with the air inlet pipe 2-2, which is fixedly connected to the hole 1-2 of the fixing plate. The spray pipe 2-3 is fixed inside the spray tower 2-1 by a bracket. The spray pipe 2-3... Multiple spray pipe holes 2-4 are provided along its length. A spiral plate 2-5 is fixed on the air inlet pipe 2-2. The edge of the spiral plate 2-5 is fixedly connected to the inner wall of the spray tower 2-1. An air outlet 2-6 is provided at the lower end of the spray tower 2-1. A collection hood 2-7 is fixed inside the spray tower 2-1.

[0015] Furthermore, the spray pipe holes 2-4 and the spiral plate 2-5 are both made of graphite.

[0016] Furthermore, the drive motors 1-4 are model STP-58D320, which is existing technology and will not be described in detail here.

[0017] Furthermore, the models of liquid feed pump 1-2-9 and liquid feed pump 2-2 are CQ40-32-160, which is existing technology and will not be described further. Working principle: When using this device, the acid mist emission pipe is fixedly connected to the gas collection hood 1-5. This device is connected to an external power source to provide power to the liquid feed pump 1 2-9 and the liquid feed pump 2 3-2. Under normal conditions, the circular flap 1-3 is horizontally set in the hole 1-2 of the fixed plate. Acid mist enters through the gas collection hood 1-5. One of the drive motors 1-4 is energized, causing the circular flap 1-3 to rotate 90°. The acid mist enters the spray tower 2-1 through the inlet pipe 2-2 via the fixed plate hole 1-2. Inside the acid mist spray tower 2-1, it moves downwards along the spiral plate 2-5. The spray liquid is pre-filled into the storage tank 3-1. The liquid feed pump 3-2 is energized, and the three-way valve 3-3 is turned towards the side of the spray device 2 where acid mist has entered. The liquid feed pump 3-2 draws the spray liquid from the storage tank 3-1, sends it through the three-way valve 3-3 into the spray pipe 2-3, and then sprays it out through the spray pipe hole 2-4. The spray liquid treats the acid mist. The spray liquid falls onto the spiral plate 2-5 and moves downwards along it to the collection hood 2-7 for collection. By setting the spiral plate 2-5, the movement time of the acid mist within the spray tower 2-1 is increased, thus allowing the spray liquid to fully interact with the acid mist. The reaction process is carried out, and the treated gas is discharged through the outlet 2-6. The liquid feed pump 2-9 is powered on to extract the spray liquid from the collection hood 2-7 and send it back to the storage tank 3-1 through the return pipe 2-8 for collection. A partition can be installed in the storage tank 3-1 to separate the unused spray liquid from the used spray liquid. When the acid mist intake is large, another drive motor 1-4 is controlled to drive the circular flap 1-3 to rotate 90°. At this time, the acid mist enters the two spray devices 2 through the two fixed plate holes 1-2 for treatment. Then, the three-way valve 3-3 is turned to the two-end passage, and the liquid feed pump 3-2 can send the spray liquid into the two spray devices 2. The intake can be adjusted according to the acid mist intake in the above way. When the acid mist intake is small, one spray device 2 can operate to reduce energy consumption. When the intake is large, both spray devices 2 can operate at the same time to avoid the acid mist treatment speed being too slow.

[0018] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
