Description

[0001] The present invention relates to a method of exhaust gas treatment,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an exhaust gas treatment method, and more particularly to an exhaust gas treatment method capable of effectively removing a vapor or an organic compound contained in an exhaust gas.

Generally, wastes are mainly used for incineration. Incineration treatment of these wastes is the most effective treatment method in terms of volume reduction and recovery of energy, and is the most widely used treatment method in regions where landfill is insufficient due to high population density such as Korea.

Recently, the necessity of preservation of the atmospheric environment has been emphasized, and it is essential to remove dioxins and nitrogen oxides generated in the combustion process of flue gas and waste. Here, dioxin is an organic compound in which two benzene rings are connected by oxygen, and is composed of 75 isomers of polychlorinated dibenzo-p-dioxins (PCDDs) and 135 isomers of polychlorinated dibenzofuran (Polychlorinated dibenzofurans, PCDFs). These substances are not only acute toxic but also have various chronic toxicity and are known as harmful substances which show immunotoxicity, reproductive toxicity, carcinogenicity and the like. These sources of dioxin are the industrial incineration facilities of the city, steel mills, industrial processes such as refining of metals, pulp mills, automobile exhaust gases, and factories that manufacture and handle chemical products such as agricultural chemicals and chlorophenols. In the case of an incinerator as a typical representative place for generating dioxins, when complete combustion of waste is performed in a state where oxygen is sufficiently present in the incinerator, carbon dioxide and water are generated and dioxins are not produced. However, when the combustion time is short and the oxygen is insufficient, incomplete combustion occurs, and dioxin precursor is formed. When this reacts with chlorine, dioxin is produced.

However, the above conventional exhaust gas treatment facility has a problem that the efficiency of removing exhaust gas is low due to poor efficiency of removing vapor or organic compounds contained in the gas.
