<p>PROBLEM TO BE SOLVED: To effectively remove a harmful gas by heating air to be purified and humidifying the air in the heated state to sufficiently exhibit gas adsorption action based on the principal of nucleus condensation. SOLUTION: The temp. of outside air to be purified flowing through an air passage F is increased by a heater 1 at first to make such a state that absolute humidity can be increased by adding a lot of steam component. Air in a supersaturated state is obtained by atomizing hot water by a humidifier 2 provided in the succeeding flow side of the heater 1. The steam molecule in the air in the supersaturated state is condensed and grown by the nucleus condensation action and the harmful gas is adsorbed by the condensed steam molecule. Next, the outside air from which the harmful gas is removed by the discharge of the condensed water with two stages of cooling action by a washer 3 and a cooler 4 and the succeeding discharge of the condensed water with an eliminator 5 is passed through a re-heater 6 to be re-heated and supplied to a clean room.</p> |
