Title:
METHOD AND APPARATUS FOR TREATING EXHAUST GAS
Document Type and Number:
Japanese Patent JP3491141
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a stable exhaust gas treatment method for reducing dioxin in exhaust gas while considering the simplificity of fly ash treatment without using energy wastefully.
SOLUTION: An exhaust gas treatment method is adapted to the detoxifying treatment of exhaust gas containing a harmful component and comprises a first process for introducing exhaust gas into an electric precipitator 4 at 200-350°C to remove soot in the exhaust gas, a second process for introducing the exhaust gas from the first process into a denitrating tower 8 and/or a dioxin removing tower to remove nitrogen oxide and/or dioxins in the exhaust gas, a third process for introducing the exhaust gas from the second process into a temp. lowering tower to quench the exhaust gas by water spraying and a fourth process for introducing the exhaust gas from the third process into a reaction bag filter 3 to spray slaked lime into the exhaust gas to remove an acidic component in the exhaust gas.
