In a wet gas scrubber which includes: a cleaning part (200) which has multiple water nozzles (210) installed in a space of a division plate (110) in a main body, and a filter part (500) for adsorbing a harmful element in an exhaust gas, an exhaust guide device of a wet gas scrubber includes: a venturi tube (320) in a housing (100H), a first pressure control part (300) for generating pressure according to flow velocity generated in an injection nozzle (310) which injects cleaning water to the internal diameter of the venturi tube (320), and a second pressure control part (400) formed under the first pressure control part (300), and which has a larger diameter compared to that of the venturi tube (320) and guides the drainage of the cleaning water to locally change a first pressure (P1) which is low and is generated in the venturi tube (320) into a second pressure (P2) on the outside of the injection hole of the venturi tube (320). |
