    摘要： A gas-liquid contactor is obtained by including a header pipe (101) for supplying washing water (20a), a kind of liquid, in a direction perpendicular to a vertical axis direction, the header pipe being disposed above a packed bed contacting section (110) through which exhaust gas (11A), a kind of gas, moves upward and passes; and spray nozzles (102) for discharging spray water (105), the nozzles being disposed, in an upward orientation, with predetermined intervals on the header pipe (101). Next, the spray water (105) that has been discharged from the spray nozzles (102) is supplied at a low liquid flow rate. Also, the discharged spray water (105) becomes a liquid film (105a) and falls downward along the surface of the header pipe (101), and then falls and spreads in the packed bed contacting section (110), so that the liquid (washing water (20a)) is made to contact the gas (exhaust gas (11A)) moving upward through the packed bed contacting section (110). Accordingly, the washing water (20a) is used to clear and remove water-soluble substances contained in the exhaust gas (11A).
