These tail gases contain carbon dioxide, carbon disulfide, hydrogen sulfide, fluorides, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid, lead, mercury, beryllium compounds, soot, and productive dust. Therefore, after being discharged into the atmosphere, they will pollute the air. At the same time, these substances enter the human body through different channels. Some substances directly cause harm and will more seriously endanger human health. During the chemical production process, acidic tail gases such as acetic acid and hydrochloric acid are often generated. If these acidic tail gases are directly discharged into the air, it will also cause environmental pollution. Therefore, it is necessary to absorb and treat the acidic tail gases before discharge. During the treatment process of acidic tail gases, in order to improve the absorption effect of acidic tail gases, a special absorption treatment device for acidic tail gases is required to reduce environmental pollution.
