Abstract

The present invention relates to a method for scrubbing gas in a cascade-type wet scrubber. In the method gas to be cleaned and containing dust and fine impurities is led into a gas distribution chamber (13) of the cascade scrubber (10) through an inlet channel (11). From the gas distribution chamber (13) the gas is led downward through vertical cascade tubes (16) to a water tank (14) from which the purified gas is led to a droplet separator. According to the invention pressurized washing liquid is sprayed through spray nozzles (20, 21, 22) to the gas to be cleaned before and/or after said gas is discharged from the cascade tubes (16). The present invention relates also to a cascade scrubber (10).
