Abstract
PURPOSE: To enhance the reduction and removal efficiency of unreacted ammonia by a mechanism wherein an exhausting gas introducing portion of a direct and an alternating current type moving layer reactor is divided into two or more upper and lower sections and NH3 gas is introduced so as to establish a gradient of an NH3 concentration which becomes higher at a lower portion of a reactor.
CONSTITUTION: An exhaust gas is controlled below about 250°C by a temperature regulator 3 and supplied to a direct and an alternating current type moving layer reactor 5, thereafter is passed through a carbonaceous catalyst filled layer 6 moving downwardly. In this point, NH3 gas 7 is introduced into an exhaust gas supplied to a reactor 5. This exhaust gas supply pipe 4 is branched to an upper and a lower direction to form a branched pipe 4', 4" 4'" and the said NH3 gas is introduced so as to increase NH3 concentration in proportion to a downward direction. The exhaust gas from a reactor 5 is discharged at a point 9, on the other hand, a catalyst is lowered within a reactor 5 while adsorbing and absorbing, thereafter taken out from a reactor bottom to a regenerator 10 and regenerated. A gas 12 containing SO2 at a high concentration is supplied to a sulfur producing apparatus or the like. Because a predetermined reaction is carried out in a reactor and a contact time of activated charcoal and exhaust gas at an upper portion is short, the consumption of NH3 is reduced at an upper portion and NH3 is consumed largely at a lower portion. So as to correspond to this condition, above described constitution is established.
