Effect of water on sulfur dioxide (SO{sub 2}) and nitrogen oxides (NO{sub x}) removal from flue gas in a direct current corona discharge reactor
- Harbin University of Science and Technology, Harbin, 150040 (China)
A direct current (dc) corona discharge reactor composed of needle-plate electrodes in a glass container filled with flue gas was designed. To clarify the influence of water on discharge characteristics, water was introduced in the plasma reactor as electrode where plate electrode is immersed, under the application of dc voltage. Experiment results show that (1) corona wind forming between high-voltage needle electrode and water by corona discharge enhances the cleaning efficiency of flue gas due to the existence of water and the cleaning efficiency will increase with the increase of applied dc voltage within definite range and (2) both removal efficiencies of NO{sub x} and SO{sub 2} increased in the presence of water, which reach up to 98% for SO{sub 2}, and about 85% for NO{sub x} under suitable conditions. These results play an important role in flue gas cleanup research.
