[0030] Further, the valve at the left end of the third pipeline 204 is opened, and the acid mist is pumped into the third pipeline 204 and the second frame 203 from outside through a ceramic pump, the acid mist is sprayed into the treatment solution through a plurality of second spray heads 10, then the external power supply of the first motor 101 is connected, the first motor 101 is started to drive the second frame 203 to rotate outside the outer wall of the second frame 203 and in the tower body 4 through a sealing bearing.

[0031] The second frame 203 drives the second spray head 10 to rotate to spray the acid mist into the treatment solution in a circumferential direction, at the same time, the first motor 101 can drive the cylinder 102 to rotate, the cylinder 102 drives the plurality of second bevel gears 104 and the stirring rod 9 to revolve, the second bevel gears 104 rotate to mesh with the first bevel gears 103 to produce rotation, wherein the first bevel gears 103 and the vertical rod 11 are fixed and do not rotate, and then the second bevel gears 103 drive the stirring rod 9 to rotate, the stirring rod 9 revolves and rotates to stir the treatment solution in two directions, at the same time, the first spray head 6 sprays the treatment solution into the acid mist, so that the acid mist and the treatment solution are fully contacted, and the treatment quality of the acid mist is increased.
