SPRAY TYPE FLUE GAS DESULFURIZATION EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a spray type flue gas desulfurization equipment capable of making a spray nozzle into a high density structure and capable of improving desulfurizing/dedusting performance without reducing the amount of an absorbing soln. being in contact with waste gas and the area capable of passing the waste gas. SOLUTION: In this equipment, a spray effective range L2 is reduced by lowering a spreading angleα2 of the absorbing soln. 1 sprayed from a spray port 10 of the spray nozzle 6 and also a floor distance H2 between the spray nozzles 6 is equalized with the spray effective range L2 and also the equipment is constituted so that the absorbing soln. 1 sprayed from the spray nozzle 6 does not collide to the inner wall surface of an absorption column 4 at a high speed spray range A.
