PROBLEM TO BE SOLVED: To return the recovered evaporated water into a cooling tower, to lower the concentration of the impurity such as additives and silica in the dispersion water, and to prevent the deterioration of water quality. SOLUTION: The air discharged from an exhaust cylinder 13 is moisturized in a saturated condition. The moisturized air in the saturated condition is sprayed in a state of being guided by a current transformation plate 17, toward an inner face of a mist collecting duct 14 connected to the exhaust cylinder 13, and indirectly cooled by the cooling water as one kind of refrigerant flowing along an outer face of the collecting duct 14 to be the supersaturated air, and the dew condensation is generated on the inner face of the collecting duct 14. The generated dew condensation water is temporarily collected by a ring-shaped water receiver 17 formed on a bottom part of the collecting duct 14, and then guided outside of the collecting duct 14 to be recovered and supplied in an upper water tank 11 as a part of spray water.
