How to deal with desulfurizer

The common desulfurizer is calcium hydroxide, which is a strong alkali and corrosive to skin.


When the skin is stained with calcium hydroxide solution, it needs to be wiped with a cloth, and then coated with a certain concentration of boric acid solution.


Desulfurizer generally refers to the agent to remove 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 the exhaust gas. All kinds of basic compounds can be used as desulfurizer.


The most commonly used desulfurizers to remove sulfur dioxide in flue gas are cheap lime, limestone and alkaline solution prepared with lime. The desulfurizer can absorb most of the sulfur dioxide in the flue gas and fix it in the fuel slag. Chemical plants and smelters often use sodium carbonate, alkaline aluminum sulfate and other solutions as desulfurizer to treat tail gas containing sulfur dioxide, which can be desorbed and recycled.


This 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 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, the slurry circulating pump and oxidation fan can be reduced and stopped, the desulfurization efficiency can be improved, and the operation cost can be reduced. It 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.
