Introduction Of Desulfurizer
Edit: Topchase Metallurgical Materials Co.,Ltd    Date: Jun 19, 2017

    Removal of sulfur dioxide from the flue gas desulfurization agent, using the most is cheap lime, limestone and alkaline solution prepared with calcareous agents. Desulfurization agent can absorb most of the sulfur dioxide in the flue gas fixed in the fuel slag. Chemical plants, smelters and other often used sodium carbonate, alkaline aluminum sulfate solution as a desulfurizer treatment of sulfur dioxide containing exhaust gas, and desorption recovery.Desulfurizer  Desulfurization agent generally refers to the removal of fuel, raw materials or other materials in the free sulfur or sulfur compounds in the control and treatment of pollutants mainly refers to the removal of sulfur oxides in waste gas (including SO2 and SO3) used in the pharmaceutical. A variety of basic compounds can be used as a desulfurizer.

    Removal of sulfur dioxide from the flue gas desulfurization agent, using the most is cheap lime, limestone and alkaline solution prepared with calcareous agents. Desulfurization agent can absorb most of the sulfur dioxide in the flue gas fixed in the fuel slag. Chemical plants, smelters and other often used sodium carbonate, alkaline aluminum sulfate solution as a desulfurizer treatment of sulfur dioxide containing exhaust gas, and desorption recovery.Desulfurizer  The mixed solution desulfurizer has surface activity, catalytic oxidation, can promote the direct reaction of SO2, accelerate the dissolution of CaCO3, promote the rapid oxidation of CaSO3 into CaSO4, strengthen the precipitation of CaSO4, reduce the liquid to gas ratio, reduce the ratio of calcium to sulfur, Of the evaporation. When the concentration of SO2 in the flue gas inlet increases, higher than the design value, the pH value of the absorption tower reaction tank decreases, and when the Ca / S ratio is needed, CaCO3 can dissolve rapidly when the capacity of the absorption tower does not need to be expanded, Increase the calcium ion concentration, keep the PH value of the slurry in the normal range, the PH value of a certain buffer effect. Extend the running time of the working section slurry, reduce the number of times with the slurry, can significantly reduce the equipment fouling, scale thinning, after washing with water rinse, dirt layer easy to fall off. The desulfurization system fouling from the dispersion and activity to reduce the deposition of fouling to reduce the slurry of chloride ions in the desulfurization equipment in a variety of materials corrosion, scaling rate are reduced to varying degrees, including carbon steel reduction Up to 74% and 79%, respectively, and PVC can be reduced by 48% and 55%, respectively. The addition of desulfurization agent can play the role of anti-corrosion and corrosion inhibition, reduce the plugging, scaling, corrosion and wear of the desulfurization nozzle, reduce the scaling, corrosion and wear of the slurry circulation pump and impeller, reduce the spare parts in the desulfurization system And replace. Broaden the choice of desulfurization materials, improve the reliability of the system. Under different conditions can reduce and disable the slurry circulating pump and oxidation fan, improve the desulfurization efficiency, reduce operating costs, suitable for coal sulfur content changes, and for high sulfur coal. In flue gas desulfurization applications, has a broad marketing advantages, can produce considerable economic and social benefits.Desulfurizer
