What is a desulfurization spray tower?
Dec 16,2024
The desulfurization spray tower is the main equipment for the absorption and purification of SO2, handling a considerable amount of SO2 flue gas and continuously purifying the flue gas in an instant. Due to the relatively fast reactions involving SO2, their internal membrane conversion coefficients are large, and the reactions occur within the membrane. Therefore, it is appropriate to use an absorption tower with a gas phase as the continuous phase, high turbulence, and a large phase interface as the desulfurization tower and desulfurization dust collector. Typically, spray towers, packed towers, spray towers, plate towers, and Venturi absorption towers can meet these requirements. Among them, the spray tower is one of the most widely used types of desulfurization towers, characterized by a simple structure and mature, reliable technology, and is widely applied in large power plants and medium and small low-sulfur flue gas treatment. For high-sulfur flue gas treatment, the non-ferrous industry mainly uses pneumatic emulsification desulfurization towers and multi-layer spray towers.
