Our wet limestone-gypsum method flue gas desulfurization systems (FGD) has adopted a spray tower for absorber having a lot of advantages as described below and provides a economy and high reliability. In addition, a large amount of know-how we have supplied for 30 years is used for our FGD systems. Advantages of Spray Tower Ideal structure with a few internal structures Its simple structure with a few internal structures eliminates scaling into the absorption tower, providing a high degree of reliability. Efficient dust removal performance In addition to high desulfurizing performance, dust removal performance is required in the absorber of the FGD that is installed at the final stage of the flue gas treatment. Since slurry sprayed in the spray tower removes fine dusts, there is no need to install a wet electric precipitator at the downstream of the SOx removal system. Low pressure losses Efficient liquid-vapor contact of particulate slurry and flue gas provides high desulfurizing performance with low pressure losses. High efficiency oxidization by the propeller atomizer The oxidation agitator which was developed by ourselves efficiently oxidizes absorbed SO2 to high-purity gypsum. The oxidation agitator uses a small amount of power to create tiny air bubbles from oxidized air, realizing efficient oxidization using a small amount of oxidized air. Less installation space Its low pressure losses allow designing of high speed gas flow in the absorber, requiring less installation space.
