[0022] Embodiment 1:

[0023] See also Figures 1 to 3 As shown, the structure of the utility model is: a salt spray filtering device, including a box body 1, wherein the box body 1 is provided with three layers of filter screens 5, namely, upper, middle and lower layers; a nozzle 6 is provided between two adjacent layers of filter screens 5 on the side wall of the box body 1; an air inlet 3 is provided below the filter screen 5 on the side wall of the box body 1, and an exhaust port 4 is provided above the filter screen 5 on the upper layer at the top of the box body 1; a water tank 2 is provided at the lower part of the box body 1, a water inlet 9 is provided at the upper end of the water tank 2, a water outlet 8 is provided at the lower end of the water tank 2, a circulating pump 7 is installed on one side of the water tank 2, the water inlet end of the circulating pump 7 is connected to the water outlet 8, and the circulating pump 7 is provided with a circulating pump 7. The water outlet is connected to the nozzle 6 through a pipeline. Specifically, the mist exhaust pipe of the salt water spray test machine is connected to the air inlet 3. The salt mist generated by the salt water spray test machine during the spraying process is discharged through the mist exhaust pipe and enters the interior of the box body 1. Then, the circulation pump 7 is started to pressurize the water in the water tank 2, and then sprayed on the top of the filter screen 5 through the nozzle 6, forming a thin water film on the surface of the filter screen 5. The salt mist passes through the filter screen 5 and the water film to filter the salt-containing mist and is discharged from the top exhaust port 4, thereby achieving the purpose of demisting and desalination; the sprayed water flows back into the water tank 2 for circulation, effectively saving water resources.

[0024] like Figure 1 , Figure 2 As shown, a float valve 10 is installed on the water inlet 9. Specifically, the water supply pipe is connected to the water inlet 9. When the liquid level in the water tank 2 is too low, the float valve 10 automatically opens the water inlet 9 to replenish the water tank 2. When the liquid level in the water tank 2 reaches a set value, the float valve 10 automatically closes the water inlet 9.

[0025] like Figure 1 , Figure 2 As shown, a drain valve 11 is provided at the lower end of the water tank 2. Specifically, when the salinity of the water in the water tank 2 reaches a saturated state, the drain valve 11 is opened to discharge the salt water in the water tank 2.

[0026] like Figure 1 , Figure 2 As shown, the nozzles 6 are distributed in a ring shape on the side wall of the box body 1 . Specifically, the nozzles 6 distributed in a ring shape can make the water sprayed by the nozzles 6 fall evenly on the filter screen 5 .

[0027] like Figure 1 , Figure 2The box body 1 is rotatably provided with casters 12 at the bottom. Specifically, the casters 12 are convenient for movement and positioning.

[0028] like Figure 1 , Figure 2 The water inlet end of the circulation pump 7 is provided with a filter 13 . Specifically, the filter 13 is used to filter impurities in the water to prevent the nozzle 6 from being blocked.

[0029] During specific use, the mist exhaust port of the salt spray test machine is connected to the air inlet 3, and the exhaust gas generated by the salt spray test machine during the spraying process is discharged through the mist exhaust pipe and enters the interior of the box body 1. Then, the circulating pump 7 is started to pressurize the water in the water tank 2, and then sprayed on the top of the filter screen 5 through the nozzle 6. The water sprayed by the nozzle 6 falls evenly on the filter screen 5, forming a thin water film on the surface of the filter screen 5. After the salt mist passes through the filter screen 5 and the water film, the salt in the salt mist dissolves in the water film and then flows back to the water tank 2, while the exhaust gas is discharged from the exhaust port 4, thereby achieving the purpose of demisting and desalination; the sprayed water flows back to the water tank 2 for circulation, effectively saving water resources.

[0030] Embodiment 2:

[0031] In this embodiment, sodium hydroxide solution is added to the water tank 2, the upper filter 5 is replaced with an activated carbon filter, and the sodium hydroxide solution is sprayed on the filter 5 through the nozzle 6 to form a water film of the sodium hydroxide solution on the surface of the filter 5. After the acidic corrosive gas passes through the filter 5 and the water film formed by the sodium hydroxide solution, the acidic corrosive substances in the acidic corrosive gas are neutralized with the sodium hydroxide solution, and then the remaining toxic substances are filtered out through the activated carbon filter, thereby filtering the acidic corrosive gas.

[0032] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
