Technical field
The utility model belongs to desulfurating dust-removing equipment technical field, and in particular to a kind of wet flue gas desulfurization tower.
Background technology
Flue gas desulfurization refers to that oxysulfide (SO is removed from flue gas or other industrial waste gases2And SO3), the SO in flue gas2
Substantially acid, it can be by removing SO from flue gas with alkali substance reaction appropriate2.The most common alkali of flue gas desulfurization
Property substance is lime stone (calcium carbonate, CaCO3), quick lime (calcium oxide, CaO) and white lime (calcium hydroxide, Ca (OH)2).Lime
Stone abundance, thus it is relatively cheap, and quick lime and white lime are all produced by lime stone by heating.In wet flue gas
In desulphurization system, alkaline matter (being typically aqueous slkali, more situations are the slurries of alkali) meets with flue gas in spray tower.Cigarette
SO in gas2It is dissolved in water, forms a kind of dilute acid soln, neutralization reaction then occurs with the alkaline matter being dissolved in water.Instead
The sulphite and sulfate that should be generated are precipitated from aqueous solution, and situation is precipitated and depends on the opposite of different salt present in solution
Dissolubility.
