A device for removing impurities from a water-containing gas, comprising: a filler material-containing cooler (50); a nozzle (63) provided in an upper section on the inside of a cooling space (51); a drainage recirculation device (68) that, by using a pump (66), supplies drainage (D) from a drainage outlet (64) provided in a drainage sink (62) in the inside floor section of the cooling space (51), to the nozzle (63) and sprays said drainage; and an alkali agent addition device (70) that adds an alkali agent (69) to the drainage (D). The filler material-containing cooler (50) has: a cooler main body (52) having the cooling space (51); a gas inlet (54) communicating with the lower side of the inside section of the cooling space (51); a gas outlet (55) communicating with the upper side of the inside section of the cooling space (51); a cooling pipe (59) arranged between the gas inlet (54) and the gas outlet (55) in the inside section of the cooling space (51), and configured so as to circulate cooling liquid (57) from a cooling liquid inlet (56) inside the cooling space (51) and guide same out from a cooling liquid outlet (58); and a filling material (61) arranged so as to vertically partition between the gas inlet (54) and the gas outlet (55) inside the cooling space (51). |
