Description

technical field [0001] The invention relates to the field of flue gas desulfurization and denitrification, in particular to an integrated tower for dust removal, desulfurization and denitrification. Background technique [0002] my country's coal resources contain a lot of high-sulfur coal. According to incomplete statistics, about 13% of the resource coal in the country has a sulfur content higher than 2%, and the coal contains a large amount of C, H, S, N and other elements. Therefore, the coal directly Combustion and emission of a large amount of pollutants has caused serious soot-type pollution in my country's atmospheric environment, which has caused great harm to natural ecology and human beings. Among them, sulfide and nitrogen compounds are the most serious, which are harmful to the natural environment and human life. The loss and harm caused are the most serious. The boiler flue gas needs to be desulfurized and denitrified before being discharged. The flue gas desulfu...
