How to deal with desulfurizer

The common desulfurizer is calcium hydroxide, which is a strong base and has certain corrosiveness to skin. When the skin is stained with calcium hydroxide solution, it needs to be wiped with a rag and then coated with boric acid solution with a certain concentration. Desulfurizer generally refers to the agent that removes free sulfur or sulfur compounds from fuel, raw materials or other materials; In the control and treatment of pollutants, it mainly refers to the chemicals used to remove sulfur oxides (including SO2 and SO3) in waste gas. Various basic compounds can be used as desulfurizers. Cheap lime, limestone and alkaline solution prepared with calcareous agent are the most widely used desulfurizers for removing sulfur dioxide from flue gas. Desulfurizer can absorb most of sulfur dioxide in flue gas and fix it in fuel slag. Chemical plants and smelters often use solutions such as sodium carbonate and alkaline aluminum sulfate as desulfurizers to treat tail gas containing sulfur dioxide, which can be desorbed and recycled. The mixed solution desulfurizer has surface activity and catalytic oxidation, which can promote the direct reaction of SO2, accelerate the dissolution of CaCO3, promote the rapid oxidation of CaSO4 to CaSO4, strengthen the precipitation of CaSO4, reduce the liquid-gas ratio, reduce the calcium-sulfur ratio and reduce the evaporation of water. Broaden the selection range of desulfurization materials and improve the reliability of the system. Under different working conditions, slurry circulating pump and oxidation fan can be reduced and stopped, so as to improve desulfurization efficiency and reduce operation cost, which is suitable for the change of sulfur content in coal and high-sulfur coal. In the application of flue gas desulfurization, it has broad market promotion advantages and can produce considerable economic and social benefits.
