It should be noted that: the circulation box 200 is disposed below the purification tower main body 100, and is used for storing and recovering the liquid medicine, and has a certain supporting function on the purification tower main body 100; the purification system 300 will extract the liquid medicine in the circulation box 200 and spray the liquid medicine in the purification tower main body 100 in sequence, and at the same time, the purification system 300 can also effectively reduce the rising rate of the acid gas entering the purification tower main body 100; the inner side wall of the purification tower main body 100 is coated with corrosion-resistant materials, so that the inner side wall of the purification tower main body 100 is prevented from being corroded by acid mist, and the service life of the acid mist purification tower 10 is prolonged.
In this way, the acidic gas entering the purification space 130 in the purification tower body 100 will slow down the rising speed under the action of the purification system 300, and will also reduce the acidity of the gas under the action of the purification system 300, and finally, the acidity of the gas discharged to the outside of the purification tower body 100 through the air outlet 120 will be significantly reduced compared to the acidity of the gas entering the purification tower body 100 through the air inlet 110.
Referring to fig. 1 again, the purification system 300 includes a circulation unit 310 and at least one purification unit 320, an input end of the circulation unit 310 is connected to the circulation space 210, each purification unit 320 is disposed in the purification space 130, each purification unit 320 includes a packing layer 321, a spraying coil 322 and a plurality of sprayers 323, the spraying coil 322 and each sprayer 323 are connected to an output end of the circulation unit 310 and are disposed at an upper end of the packing layer 321, and a plurality of spraying holes (not shown) are disposed on a side wall of the spraying coil 322.

Thus, in the practical application process, the liquid medicine that the circulation unit 310 is taken out from the circulation box 200 has filtered most of the particles, and the spraying holes are effectively prevented from being blocked by the particles while the particles are prevented from wearing the circulation unit 310, the wearing of the circulation unit 310 can cause insufficient spraying pressure of the sprayer 323 and the spraying coil 322, and the blockage of the spraying holes can cause the sprayer 323 and the spraying coil 322 to be incapable of covering the acid gas at different heights. Therefore, by providing the filter 201 in the circulation box 200, the durability and the acid mist purification efficiency of the acid mist purification tower 10 can be improved to some extent.
Specifically, the filter screen 201 has a first isolation layer 2110, an activated carbon layer 2120 and a second isolation layer 2130, which are sequentially disposed, wherein the first isolation layer 2110 has a plurality of first filtering holes 2111, and the second isolation layer 2130 has a plurality of second filtering holes 2131.

The purification efficiency of the acid mist purification tower 10 is greatly improved.
Preferably, the water circulation pump 311 is a corrosion resistant pump. Thus, the corrosive substance remaining in the chemical liquid can be effectively prevented from corroding the circulating water pump 311, and the service life of the whole acid mist purification tower 10 can be prolonged.
