The absorption tower deatomizer consists mainly of fixed devices such as wavy blades, plates and strips. In the process of wet desulphurization, the absorption tower is easy to produce a "fog" with a particle size of 10--60 micron. The fog not only contains water, but it also dissolves sulphuric acid, sulphate, sulfur dioxide and so on. It also causes fan, heat exchanger and heat exchanger. The defiling and serious corrosion of the flue, therefore, the requirement for the absorption equipment to remove the mist in the wet process desulfurization process, and the purified gas should be fogged before leaving the absorption tower.
