Oil immersion type sulfur hexafluoride degradation treatment device and treatment method based on medium discharging

Abstract

The invention discloses an oil immersion type sulfur hexafluoride degradation treatment device and treatment method based on medium discharging. The oil immersion type sulfur hexafluoride degradationtreatment device comprises a medium blocking discharging reactor (2), and a high frequency alternating-current voltage source (1) is connected with an outer electrode and an inner electrode of the medium blocking discharging reactor through a wire; one end of the medium blocking discharging reactor is connected with a gas inlet; the other end of the medium blocking discharging reactor is connectedwith an alkali liquor absorption pool (4); the medium blocking discharging reactor (2) is placed in a sealed oil tank (3), and the sealed oil tank (3) is filled with transformer oil. The technical problems in the prior art are solved that only sulfur hexafluoride gas is collected, purified and stored, and sulfur hexafluoride is not decomposed and safely exhausted.

Description

technical field [0001] The invention belongs to the sulfur hexafluoride degradation technology, in particular to an oil-immersed sulfur hexafluoride degradation treatment device and treatment method based on dielectric discharge. Background technique [0002] Sulfur hexafluoride (SF 6 ) Due to its good electrical properties and excellent arc extinguishing performance, it is widely used as an insulating dielectric material in various high-voltage electrical equipment. Furthermore, since SF 6 It is a colorless, odorless, non-toxic, non-flammable and non-corrosive inert gas. It is also widely used in metal smelting, semiconductor manufacturing, medical, chemical, atmospheric tracer and aerospace industries. But studies have shown that SF 6 The potential value of the greenhouse effect (Global Warming Potential, GWP) is 23900 times that of CO2, and SF 6 The degradation rate in the atmosphere is very slow, and it takes about 3200 years, so in the "Kyoto Protocol" signed in 199...
