Abstract
PURPOSE: To improve the efficiency of denitrification, prevent white smoke generation and remove dioxin and mercury by a method wherein the high temperature exhaust gas discharged from a refuse incinerator is cooled down, passes through a reactor and a bag filter and is heated by a heat exchanger provided between the bag filter and a denitrofication apparatus.
CONSTITUTION: The exhaust gas discharged from a refuse incinerator 1 is sent to a reactor after cooled, and alkaline absorbing agent is sprayed into the exhaust gas to neutralize hydrogen chloride and sulfur oxides. The exhaust gas is cooled down to a target temperature (120-180°C) in the course of this process so that mercury compounds are removed when it passes through a bag filter 6, and dioxine generation control and removal take place. Before led to a denitrification apparatus 8, the exhaust gas is given heat from white smoke prevention heated air at an exhaust gas heating heat exchanger 7 and its temperature is raised. Then, the white smoke prevention air heated at the exhaust gas heating heat exchanger 7 and the exhaust gas after passing through the exhaust gas heating heat exchanger 7 are mixed together by a mixing device 10 and the exhaust gas (D point) is discharged into the atmosphere.
