Here, the housing contains fine salt, and the ice maker outputs ice blocks at regular intervals. After the output ice blocks hit the receiving plate, the receiving plate causes the housing to shake, and then the fine salt in the housing is intermittently poured into the water box, increasing the specific heat capacity of the cold water in the water box, and then the ice blocks further cool the cold water, effectively improving the cooling effect on the acid mist.

[0008] In a preferred example, the water box can be further configured with an opening on the top, and the water sprayers are vertical and penetrate the opening.

Here, the shell is filled with fine salt, and then the ice block machine outputs ice blocks at regular intervals. After the output ice blocks hit the receiving plate, the receiving plate drives the shell to shake, and then the fine salt in the shell is intermittently sprinkled into the water box, increasing the specific heat capacity of the cold water in the water box, and then the ice block further cools the cold water, effectively improving the cooling effect on the acid mist.

[0015] 2. In the utility model, the acid mist is injected into the acid mist absorption tower through the smoke inlet pipe. The acid mist is absorbed by countercurrent contact with the absorption liquid sprayed from the top in the filler area of the acid mist absorption tower.
