According to the gradual implementation of environmental law, industrial exhaust substances such as sulfur dioxide and nitrogen oxides also need to increase control, industrial exhaust gas desulfurization is indispensable coal columnar activated carbon, industrial exhaust gas desulfurization is an efficient resource smoke gas desulfurization process, it can not only eliminate the SO2 in the flue gas pollution, recycling and the use of activated carbon had experienced deep-processing of waste can be able to achieve the purpose of recycling. Currently, the worldwide application of industrial exhaust gas desulfurization and denitrification technology no less than 60 species, some of these technologies have been industrialized gold charcoal, activated carbon which is considered as one way to have practical value. Columnar activated carbon coal desulfurization capable of simultaneous desulfurization and denitrification treatment coal columnar activated carbon, denitrification rate can reach 50% -80%. Coal columnar activated carbon adsorption desulfurization device has two kinds of dry and wet equipment, dry method for handling larger occasions, when dealing with a large amount to 50-60 million standard cubic meters per hour, with a dry method works best deal . The wet applied to less than 10 million standard cubic meters per hour occasions. Columnar activated carbon coal flue gas desulfurization role in the development of our industry, the production process gases into the atmosphere increasing number of atmospheric lead pollution is worsening, various dyes home burning fumes into the atmosphere in harmful sulfur dioxide is the main ingredient, which is why in some places appear prominent problem of acid rain, sulfur dioxide worldwide each year, according to statistics released into the atmosphere to a million tons of super-human health, metal corrosion, growth and nature of crop caused great harm. The method to remove sulfur dioxide smoke a lot, columnar activated carbon adsorption is one of them, columnar activated carbon adsorption from the flue gas desulfurization is capable of removing low concentrations of sulfur dioxide Nutshell granular activated carbon, activated carbon adsorption of sulfur dioxide columnar Only in sulfur dioxide gas for the presence of a separate physical adsorption of activated carbon, columnar activated carbon adsorption capacity of sulfur dioxide to the physical form of very small, mostly due to the catalytic surface columnar activated carbon is oxidized to form sulfuric acid, in the form of sulfuric acid present within the pores of the activated carbon.
