<p>PROBLEM TO BE SOLVED: To provide a swirling system exhaust gas desuperheating tower which can previously prevent sticking of water particles on a wall surface due to unbalance between a swirling speed (angular velocity) of exhaust gas in an evaporation space and a diameter of the water particle and trouble caused thereby without using a mechanical device. SOLUTION: An evaporation section 2 of the upper part, a gas introducing section 3 of a lower part and a taper-shaped hopper section 4 of a bottom part are provided at an outer tower 1 being a tower main body. Further an inner tower 5 communicating with the evaporation section 2 is concentrically provided inside the gas introducing section 3, a lower end opening of the inner tower 5 is arranged at a prescribed height of the gas introducing section 3, a water spraying nozzle 6 is disposed inside the inner tower 5, an entrance duct section 8 joined to a side part of the gas introducing section 3 is arranged parallel to a tangential direction of the gas introducing section 3 so that a part of the inner tower 5 faces an opening of the entrance duct section 8, an exit duct section 9 is arranged at a top part of the evaporation section 2 and a dust exhaust port 10 is formed at a tower bottom surface of the hopper section 4.</p> |
