PURPOSE:To treat continuously and efficiently exhaust gas containing dust, NOx and SOx such as boiler exhaust gas, diesel engine exhaust gas or the like. CONSTITUTION:Exhaust gas is penetrated through a moving layer 12 for desulfurization and denitration, or through a moving layer 40 for dust removal and with moving layer 42 for desulfurization and denitration, or through the moving layer 40 for dust removal, a moving layer 72 for denitration and a moving layer 74 for desulfurization, or through the moving layer 40 for dust removal, the moving layer 74 for desulfurization and the moving layer 72 for denitration, and a reducer is added to exhaust gas to remove SOx and NOx in the exhaust gas simultaneously. Dust containing particles are extracted continuously or intermittently to be separated into the particles and dust and a pulverized material. The separated particles are circulated to the moving layers and reused. In that case, particles for desulfurization and particles for denitration are regenerated and then circulated to the moving layers. |
