EXHAUST GAS TREATMENT APPARATUS |
摘要 |
<p>An object of the present invention is to easily reduce dust having large particle diameter that affects blocking and abrasion to prevent deposition thereof in a reactor. An exhaust gas NOx removal apparatus comprises a NOx removal rector having a catalyst layer for removing nitrogen oxides in a combustion exhaust gas; a duct structure having a stab-up point at which a flow of the exhaust gas changes from a horizontal direction to a vertical direction in an exhaust gas duct on the upstream side of the NOx removal reactor; a tilt thin plate slit in which a number of thin plates are disposed in the duct of the horizontal direction of an inlet of the stub-up point or/and in an inlet of the catalyst layer in the NOx removal reactor in a vertical direction with a slit width smaller than an opening width of the catalyst layer at a predetermined inclination angle relative to the cross-section of an exhaust gas flow path; and a dust collecting/discharging portion attached to the lower end of a tilt thin plate slit.</p> |
