[0002] Acid mist refers to mist-like acidic substances that are highly corrosive and pose a great threat to both humans and the environment. Acid mist is mainly produced in the acid-using process in the chemical, electronics, metallurgical and other industries. Acid mist sedimentation separators are mainly used to treat acid mist in industrial waste gas, using the material's own gravity and inertia to perform separation operations.

[0003] Existing acid mist sedimentation separators are usually only equipped with a single-layer spray structure, with low spray efficiency. The gas is directly discharged after spray purification, which may sometimes have an incomplete purification effect, resulting in the presence of harmful gases in the discharged gas, poor separation effect, and insufficient environmental protection.

By setting up a double-layer spray purification structure, the purification efficiency can be improved, and by setting up a reaction tank with a stirring assembly, some of the residual harmful substances can be chemically reacted to convert them into non-toxic and harmless gases, which can make the purification and separation more thorough, the separation effect better, and the environmental protection better.

[0024] See also Figure 3 In this embodiment, the packing assembly includes a filter plate 301 and a packing layer 302. Two groups of filter plates 301 are evenly distributed from top to bottom along the inner wall of the separation tank 1. The upper ends of the two groups of filter plates 301 are provided with a packing layer 302 for increasing the purification efficiency. By setting two groups of packing layers 302 to filter the acid mist in sequence, the purification efficiency can be improved.

[0025] See also Figure 4 In this embodiment, the spray assembly includes a liquid storage tank 401, a liquid inlet pipe 402, a hydraulic controller 403, an annular spray plate 404, a nozzle 405, a first connecting pipe 406 and a second connecting pipe 407. The annular spray plate 404 is evenly arranged around the upper outer side of the separation tank 1. Eight groups of nozzles 405 for spraying neutralizer are evenly fixedly installed around the inner side of the annular spray plate 404. The nozzles 405 pass through the outer side of the separation tank 1 and extend to the inner side. By evenly arranging the nozzles 405 around the separation tank, the spraying can be more uniform. The two groups of nozzles 405 are connected through the first connecting pipe 406. The first connecting pipe 406 is connected to the liquid storage tank 401 through the second connecting pipe 407.

[0026] See also Figure 5 In this embodiment, the stirring assembly includes a drive motor 501, a rotating shaft 502 and a stirring rod 503. The stirring rods 503 for stirring the reaction liquid are evenly fixedly installed around the outer side of the rotating shaft 502. The drive motor 501 is provided with an output shaft. The output shaft of the drive motor 501 passes through the lower end of the support platform 11 and extends to the interior of the reaction tank 2 to drive the rotating shaft 502 to rotate. By setting the drive motor 501 to drive the stirring rod 503 to rotate and stir the reaction liquid, the reaction speed can be accelerated.

[0027] When working, first the support platform 11 is moved to the corresponding position so that the foot column 12 forms a stable support for the support platform 11;

[0028] Then open the control valve at the mist inlet pipe 6, use the fan 7 to suck an appropriate amount of acid mist into the separation tank 1 through the mist inlet pipe 6, and then close the control valve outside the mist inlet pipe 6;

[0029] The acid mist then passes through the seasoning assembly from bottom to top. During its rise, it is sprayed and purified by the spray assembly. The neutralizer is introduced into the liquid storage pipe through the water inlet pipe, and the hydraulic pressure is adjusted to an appropriate level by the hydraulic controller 403. The liquid reagent enters the two sets of annular spray plates 404 through the first connecting pipe 406 and the second connecting pipe 407, so that the nozzle 405 evenly sprays the liquid onto the acid mist to purify the acid mist.

[0030] During the treatment process, the liquid and some harmful substances enter the reaction tank 2, and an appropriate amount of reaction reagent is introduced through the feed hopper 9, so that the reaction reagent neutralizes and purifies the residual harmful substances;

[0031] During the reaction, the stirring assembly is used for stirring, and the driving motor 501 drives the rotating shaft 502 to drive the stirring rod 503 to rotate and stir the reaction liquid;

[0032] Finally, after the separation is completed, the purified gas is discharged to the outside by opening the control valve outside the exhaust pipe 8, and the reaction wastewater is led out to the corresponding location through the drain valve 10.

[0033] Through the above steps, by setting up a double-layer spray purification structure, the purification efficiency can be improved. By setting up a spray assembly with two sets of annular spray plates 404, the acid mist can be sprayed and purified step by step from bottom to top, and by setting up a packing assembly matched with the spray assembly, the acid mist can be filtered in sequence through the two sets of packing layers 302, thereby improving its purification efficiency. By setting up a reaction tank 2 with a stirring assembly, some residual harmful substances can be chemically reacted to convert them into non-toxic and harmless gases, which can make the purification and separation more thorough, the separation effect better, and the environmental protection better. By setting a drive motor 501 can drive the rotating shaft 502 to drive the stirring rod 503 to rotate and stir the reaction liquid, so that it is mixed with the harmful gas more evenly, thereby accelerating the reaction speed. Under the mutual cooperation of the filler component, the spray component and the stirring component, the separation and purification efficiency can be greatly improved, and the separation effect can be better, faster and more efficient, so as to solve the problem that the existing acid mist sedimentation separator is usually only provided with a single-layer spray structure, the spray efficiency is low, and the gas is directly discharged after the spray purification, which may sometimes not be a thorough purification effect, resulting in the presence of harmful gases in the discharged gas, poor separation effect, and insufficient environmental protection.
