| 摘要 |
A gas sparger (30) is operative for supplying an oxidation gas containing oxygen to a tank (18) of a wet scrubber which is operative for removing sulphur dioxide from a process gas by means of a slurry (S). The gas sparger (30) is provided with at least a first liquid supply nozzle (38), which is located inside an oxidation gas supply duct (32) and is operative for spraying a liquid containing water towards a first oxidation gas supply nozzle (44). The oxidation gas supply duct (32) has a characteristic cross-sectional measure, such as a diameter (D), at said first oxidation gas supply nozzle (44). The first liquid supply nozzle (38) is located a distance (L1) of maximum 5 times said characteristic cross-sectional measure (D) from said first oxidation gas supply nozzle (44).
