PURPOSE:To miniaturize equipment by treating harmful substances such as soot, hydrogen chloride, NOx, SOx, dioxin or heavy metals in a short process. CONSTITUTION:Exhaust gas is passed through an electric precipitator 10 and subsequently mixed with ammonia to be passed through an adsorbing tower 14 packed with activated carbon to simultaneously treat and remove harmful substances. Activated carbon is discharged from the lower part of the adsorbing tower 14 while the exhaust gas is subjected to adsorbing treatment to be regenerated in a desorbing tower 16 and the regenerated activated carbon is again returned to the upper part of the adsorbing tower 14 and activated carbon is continuously supplied to perform continuous operation. |
