<p>PROBLEM TO BE SOLVED: To provide desulfurization equipment capable of being miniaturized and capable of reducing the use amount of a carbonaceous adsorbing material without damaging the function of the carbonaceous adsorbing material and reduced in cost. SOLUTION: A part of the desulfurized gas discharged from the gas outlet 3d of the desulfurization equipment 3 is supplied into a hopper 3Z through a desulfurized gas supply line L9 to raise the pressure in the hopper 3Z and exhaust gas is prevented from flowing into the hopper 3Z from a gas treatment part 3X, which has the carbonaceous adsorbing material arranged therein and permits the exhaust gas to pass, through a discharge part 3Y. Since the desulfurized gas is desulfurized and cleaned in the gas treatment part 3X, the warm desulfurized gas is utilized to prevent the desulfurized gas from draining without exerting adverse effect on the carbonaceous adsorbing material by the desulfurized gas.</p> |
