工業气体冷却时广泛地应用填料洗滌塔。不飽和的烟道气从塔底上来,与自塔頂噴淋下来的水逆流接触。在塔底一般發生气体冷却,同时由于水分蒸發增加了烟道气的湿含量,这样热傳遞与質量傳遞方向相反,直到烟道气中蒸汽分压增加到相当于这时气体的 Filler scrubbers are widely used when industrial gases cool down. Unsaturated flue gases come up from the bottom of the tower and come into countercurrent contact with the water sprayed from the top of the tower. Gas cooling generally occurs at the bottom of the column and the moisture content of the flue gas is increased by evaporation of water, so the heat transfer is in the opposite direction to the mass transfer until the vapor partial pressure in the flue gas is increased to a level corresponding to the gas
