<p>PROBLEM TO BE SOLVED: To effectively reduce gas passing resistance while obtaining high gas purifying performance. SOLUTION: A water spraying means 6 for spraying washing water W to the subject passing gas A to be purified is provided, and many heat-transfer members 4a and 4b for cooling and dehumidifying the passing gas A by subjecting the passing gas A and a refrigeration medium R to heat-exchange are arranged in dispersed state at the water spraying area of the water spraying means 6. Preferably, the device constitution in which a heat-transfer pipe 4a of the cooling coil 4 for subjecting the passing gas A and the refrigeration medium R to the heat exchange or a fin 4b incidental to the heat-transfer pipe 4a is used as the heat-transfer member and the gas passing area of a cooling coil 4 is used as the water spraying area of the water spraying means 6.</p> |
