Aiming at the effective treatment of SO₂ gas with wide range, large displacement, and heavy pollution, the traditional desulfurization technology has economic and technical limitations, while non-thermal plasma technology has the advantages of high removal efficiency, and wide applicability for purifying polluted gases, and has received extensive attention and research.. The article introduces the research progress of three non-thermal plasma technologies removal of SO₂ by electron beam, corona discharge, and dielectric barrier discharge. The technical mechanism and influencing factors are reviewed, and possible research trends of non-thermal plasma desulfurization technology are analyzed.
