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 desulfurization is capable of removing low concentrations of sulfur dioxide from the flue gas, columnar activated carbon adsorption of sulfur dioxide only when sulfur dioxide gas alone for iodine value of coconut shell activated carbon physical adsorption, columnar activated carbon dioxide in the form of physical adsorption is very small, mostly due to the catalytic oxidation of the surface columnar activated carbon shell activated carbon iodine value, generate sulfuric acid, sulfuric acid is present in the form of activated carbon within the pores. Trivalent phosphorus compounds, these substances usually phosphate present in sewage, and so can not be a large number of activated carbon adsorption. Advanced waste water treatment in the chemical refining stage, they can be effectively inorganic coagulant (alum, ferric, lime) becomes insoluble, and allowed to go out. Removal is generally greater than 90%. On nitrogen compounds for the activated carbon, has not been proposed a reliable method for removing nitrogen compounds in a variety of conditions suitable for. Mainly ammonia nitrogen and organic nitrogen present in raw sewage wastewater. Part of the organic nitrogen into ammonia when secondary treatment; part by chemical clarification removal; partially removed by activated carbon. Clarify whether chemical or activated carbon, can not remove ammonia. Effective economic regeneration of activated carbon for use in advanced wastewater treatment is indispensable. In a fraction of the cost of a new carbon-carbon successfully regenerated tablets, is the current regulatory method of operation. Recovery rate of 90-95%. Renewable carbon with water quality and water treatment was the same with the new carbon, the adsorption capacity is slightly lower, in other words, the use of renewable carbon-carbon cycle as good as the new chief.
