DUST ATTACHMENT PREVENTING DEVICE FOR EXHAUST GAS COOLING TOWER

PROBLEM TO BE SOLVED: To dispense with use of a large-scaled machine or dust removing work causing a heavy load on workers, by effectively preventing attachment of dust in gas circulation pipes. SOLUTION: In an exhaust gas cooling tower in which the plurality of gas circulation pipes 2 for circulating an exhaust gas, are disposed in parallel with each other, and a refrigerant is circulated in an outer periphery of the gas circulation pipes 2, nozzles 56 are disposed to blow the compressed air toward inflow ports 21 of the gas circulation pipes 2. The gas circulation pipes 2 are concentrically disposed, the plurality of nozzles 56 are disposed on a cylindrical manifold 55 extending in the radial direction of the concentric circle at intervals equal to those of the concentric circle, and a cyclone decelerator 57 is disposed to swivel the manifold 55 around a center of the concentric circle.
