PROBLEM TO BE SOLVED: To provide a gas-liquid contactor which recovers harmful substances by bringing a gas containing harmful substances into contact with a liquid for absorbing the harmful substances, and whose reduction of a recovery rate of the harmful substances can be suppressed by preventing a liquid component containing the harmful substances from being discharged to the outside with discharge of the separated gas component after separating the gas and the liquid brought into contact with each other.SOLUTION: A gas-liquid contactor 1 related to the present invention includes: a first gas-liquid contact part 10 having a gas introduction port 11 disposed at a tower top part and nozzles 12; a cylindrical second gas-liquid contact part 20 which is disposed in communication with the first gas-liquid contact part 10 and in which a contact part 20A with the first gas-liquid contact part 10 has a venturi structure; a gas-liquid separation part 30 for separating the gas and the liquid discharged from a lower end of the second gas-liquid contact part 20; and a gas discharge part 40 which is disposed around the second gas-liquid contact part 20 and discharges the gas separated by the gas-liquid separation part 30 from a gas discharge port 41 disposed at an upper part.SELECTED DRAWING: Figure 1 |
